System fo-r monitoring access to a restricted area, comprising a module housed
below or above the gate
The present invention relates to a system for monitoring access to a restricted
area, of the type comprising at least one monitoring device for monitoring the entrance
5 andlor the exit in the restricted area of users using a pedestrian gate, specific to the
monitoring device, of the entrance andlor of the exit of the restricted area, the monitoring
device comprising:
- a system for authorizing circulation, comprising a central unit and at least one
document reader, said or each document reader being adapted so as to
communicate with an access document of a user, and the central unit being
adapted for determining whether the user owner of the access document is
authorized to use the gate, and
- a signing system adapted for showing the user whether helshe is either
authorized or not to use the gate, said signing system comprising at least
one peripheral adapted for changing state and a module for controlling said
or each peripheral, the control module being adapted for controlling the
change of state of said or each peripheral when the central unit of the
circulation authorization system has determined that the user owner of the
displacement document is authorized to use the gate.
20 Such access control systems are known, notably from WO 20051015507. They
generally control the access to an inside of a building or to a common transportation
network. Most often, a peripheral of the signing system is a device for obstructing the gate
which comprises a mobile member forming an obstacle and an actuator for controlling the
displacement of said obstacle so as to selectively obstruct or clear the gate. The obstacle
25 is commonly formed by a barrier or a gate.
On a current basis, the circulation authorization system and the signing system,
except for the obstacle, are housed in a box delimiting a lateral edge of the pedestrian
gate.
Ordinarily, the access control system comprises a plurality of access control
30 devices juxtaposed to each other and which will together close a corridor for accessing
the restricted area, said corridor typically extending between two walls of the building to
which access should be controlled. The boxes of the different access control devices
delimit together the pedestrian gates. For a predetermined corridor width, the number of
gates which it is possible to form in said corridor therefore depends on the width of each
35 gate and on the size of each box.
2
A constant requirement of the access control systems is to maximize the
pedestrian flow. For this purpose, it is for example possible to increase the number of
monitoring devices placed in a same corridor by reducing the size of each monitoring
device. However, this possibility is limited by the fact that the width of the pedestrian gates
5 should remain sufficient for allowing easy crossing of the pedestrians and that the boxes
should have a minimum size in order to efficiently protect the equipment which they
contain.
An object of the invention is to reduce the size of the monitoring devices of an
access control system to a restricted area.

The access control system 10, illustrated in Figs. 1 to 3, is intended to control the
entry of users into a restricted area 12. Alternatively, the access control system 10 is
intended to exclusively control the exit, or the entry and exit of users in the restricted area
30 12.
For this purpose, the access control system 10 comprises a plurality of monitoring
devices 20 juxtaposed to each other so as to isolate the restricted area 12 from a free
area 14, any user passing from the restricted area 12 to the free area 14 having to
necessarily use a pedestrian gate 22 specific to one of the monitoring devices 20.
7
The restricted area 12 is typically an interior space of a building, a network of
common transportation, or an amusement park. It is resewed for the possessors of a valid
access document.
Each monitoring device 20 is adapted for controlling the entrance into the
5 restricted area 12 of users using the pedestrian gate 22 specific to the monitoring device
20. Alternatively, each monitoring device 20 is adapted for exclusively monitoring the exit,
or the entry and the exit of users passing through the pedestrian gate 22.
By (( pedestrian )) gate, is meant that each gate 22 is adapted for the crossing of a
pedestrian, preferably a pedestrian in a Rollator, and of hislher luggage, but not of an
10 automobile. For this purpose, each gate 22 typically has a width comprised between 40
cm and 80 cm.
Each monitoring device 20 comprises a power supply module 24, a control module
26, a device 28 for obstruction of the gate 22 specific to the monitoring device 20, two
members 36 for delimiting the lateral edges of the gate 22, a sensor 34, and a device for
15 interacting with the user comprising a display device on the ground 30, a document reader
32 and a member for emission of sound 38 (Fig. 5).
The power supply module 24 is adapted so as to shape an electric current for
supplying power to the monitoring device 20, so as to provide a stable electric power
supply and without any cutting of to the remainder of the monitoring device 20. This type
20 of power supply module is known and is generally designated under the name of
uninterruptible power supply or UPS.
The power supply module 24 is housed in a first compartment 40 positioned in a
cavity 42 extending under the gate 22 specific to the monitoring device 20. In the
illustrated example, the cavity 42 is common to all the monitoring devices 20 and extends
25 under all the gates 22.
With reference to Fig. 4, the compartment 40 contains, in addition to the power
supply module 24, a outlet 44 for connecting to an electricity network for powering the
access control system 10, a outlet 46 for outputting the shaped electric current, and a
maintenance outlet 48, the power supply module 24 being electrically connected to each
30 of the outlets 44, 46, 48.
Referring back to Figs. 1 and 2, the control module 26 is a computer, for example
an industrial computer adapted so as to powered with a voltage of 12 V. It has
communication means (not shown) with the obstruction device 28, the display device 30,
the document reader 32, the sensor 34 and the sound emission member 38.
35 The control module 26 is housed in a second compartment 50 positioned in the
cavity 42.
8
With reference to Fig. 5, said compartment 50 contains, in addition to the control
module 26, a power supply socket 52 electrically connected to the output outlet 42 of the
compartment 40, a maintenance socket 54, a transformer 56 for adapting the current
provided to the power supply outlet 52 at the power supply voltage of the control module
5 26, a keyboard 58, for programing the control module 26, and the sound emission
member 38.
Each delimitation member 36 is common to the monitoring device 20 and to one of
the monitoring devices 20 which is adjacent to it, except in the case when the monitoring
device 20 is only juxtaposed to a single other monitoring device 20, in which case only
10 one of the delimitation members 36 is common to the monitoring device 20 and to a
monitoring device 20 which is adjacent to it.
Each delimitation member 36 comprises a post 90 and optionally a stringer 91.
The post 90 is substantially oriented vertically. The stringer 91 is oriented substantially
horizontally, parallel to the axis of the gate 22. The stringer 91 is at a distance from the
15 floor 93 of the gate 22, and is borne by the post 90.
Each post 90 preferably has, as illustrated in Fig. 14, a horizontal section
elongated parallel to the axis of the gate 22.
Each post 90 is preferably in steel.
With reference to Figs. 14 and 15, each post 90 is held on the ground by two
20 attachment devices 98. These attachment devices 98 are positioned on each side of the
post 90 along the axis of the gate 22. Each attachment device 98 is secured to a lower
end of the post 90.
Each attachment device 98 is preferably in steel.
Each attachment device 98 comprises two flanges 100 forming together an angle
25 comprised between 90" and 16O0, and a plate 102 connecting the flanges 100 to each
other.
Each flask 100 is substantially oriented vertically, and the plate 102 is substantially
oriented horizontally. The flanges 100 converge towards the post 90. This configuration of
the attachment device 98 allows good transmission of the forces exerted on the post 90,
30 along the axis of the gate 22, towards the ground. The resistance of the post 90 to
detachment is thus increased.
The plate 102 has a plurality of orifices 104 for letting through attachment
members (not shown), for example screws, for attaching the plate 102 to the ground.
The attachment devices 98 are positioned in the cavity 42.
35 Returning to Figs. 1 to 3, the obstruction device 28 comprises an obstacle
positioning device 60, adapted for positioning an obstacle 62 across the gate 22 specific
9
to the monitoring device 20. This obstacle positioning device 60 is housed in a third
compartment 64 positioned in the cavity 42.
With reference to Fig. 6, the compartment 64 contains, in addition to the obstacle
positioning device 60, a power supply outlet 65 electrically connected to the output socket
5 42 of the compartment 40, a maintenance socket 66, and an electric converter 68 for
converting the current provided at the power supply outlet 65 into a current adapted for
supplying power to the obstacle positioning device 60.
According to a first exemplary embodiment of the first embodiment of the
invention, illustrated in Figs. 6 to 16, the obstacle 62 comprises at least one movable
10 member 70 between a deployed configuration, in which it extends through the passage
22, and a retracted configuration, in which it is cleared from said gate 22, and the obstacle
positioning device 60 is formed by an actuator mechanically connected to said or each
movable member 70 for driving it between its deployed configuration and its retracted
configuration.
15 In the illustrated example, the obstacle 62 is formed with two movable members
70, said movable members 70 being barriers. Alternatively, the movable members 70 are
gates.
Each barrier 70 is adapted so as to be oriented horizontally and perpendicularly to
the axis of the gate 20 when it is in a deployed configuration, and:
20 - according to a first alternative, illustrated in Figs. 11 to 13, in order to be
oriented parallel to the axis of the gate 20 when it is in a retracted position, or
- according to a second alternative, illustrated in Fig. 16, for being oriented
vertically when it is in a retracted configuration.
The actuator 60 is an electric motor, for example a servomotor with variable speed.
25 It preferably has as many output shafts 80 as there are movable members 70. In the
illustrated example, the actuator 60 thus has two output shafts 80. Alternatively, the
obstacle 62 is formed with a single movable member 70, for example a gate, and the
actuator 60 then has a single output shaft 80.
With reference to Fig. 7, the mechanical connection between the actuator 60 and
30 each movable member 70 comprises an intermediate shaft 72, substantially oriented
horizontally and perpendicularly to the axis of the gate 22, an obstacle shaft 74,
substantially oriented vertically, a first device 76 for coupling the obstacle shaft 74 with the
intermediate shaft 72, and a second device 78 for coupling the obstacle shaft 74 with the
movable member 70.
35 The intermediate shaft 72 rotatably around its axis is secured to an output shaft 80
of the actuator 60. In the illustrated example, the output shaft 80 defines a cavity 82 for
10
receiving the intermediate shaft 72, and the coupling of the output shaft 80 with the
intermediate shaft 72 is achieved by cooperation of a rib 84 (Fig. 10) radially protruding
from a wall of the cavity 82 with an axial groove 86 (Fig. 9) made in the intermediate shaft
72. Returning to Fig. 7, a compression spring 88 is positioned in the cavity 82 and presses
5 against a bottom (not shown) of the cavity 82 and against an end 89 of the intermediate
shaft 72 so as to urge the shaft 72 outwards from the cavity 82. This gives the possibility
of facilitating the installation of the obstruction device 28
The obstacle shaft 74 runs along the post 90 of one of the delimitation members
36 of the monitoring device 20.
10 The first coupling device 76 is adapted so that the rotation of one of the shafts 72,
74 around its axis drives into rotation the other shaft 72, 74 around its axis. For this
purpose, the first coupling device 76 is for example an angled gearbox such as the
gearbox ~ l i d e - ~ ifrtoem~ T~olo matic.
According to the alternative of Figs. 11 to 13, the second coupling device 78 is a
15 clamping ring, secured to the movable member 70 and tightened around the obstacle
shaft 74. The movable member 70 and the obstacle shaft 74 are thus rotatably secured
around the axis of the obstacle shafl74.
In order to stiffen the obstacle shaft 74, the post 90 bordered by said shaft 74 then
bears, at its upper end, a cap 92 defining an orifice 94 (Fig. 13) for receiving an upper end
20 96 of said obstacle shafl 74. Thus, the obstacle shaft 74 is held at its lower and upper
ends, which avoids its flexing.
According to the alternative of Fig. 16, the second coupling device 78 is adapted
so that the rotation of the obstacle shafl 74 around its axis drives the mobile member 70
into rotation around an axis substantially parallel to the axis of the gate 22. For this
25 purpose, the second coupling device 78 is for example an angled gearbox such as the
gearbox s l i d e - ~ i t fero~m Tolomatic.
In order to stiffen the obstacle shaft 74, the second coupling device 78 is secured
to the post 90 bordered by said shafl 74. Thus, the obstacle shaft 74 is held at its lower
and upper ends, which avoids its flexing.
30 The intermediate shafls 72 are aligned transversely with each other. In other
words, the axes of the intermediate shafts 72 are comprised in a same vertical plane.
The obstacle shafts 74 are transversely aligned with each other. In other words,
the axes of the obstacle shafls 74 are comprised in a same plane perpendicular to the
axis of the gate 22.
11
According to a second exemplary embodiment of the first embodiment of the
invention, illustrated in Figs. 17 to 20, the obstacle 62 is a hologram, and the obstacle
positioning device 60 is a hologram generator.
The hologram generator 60 is adapted for generating the hologram 62 so that it
5 extends across the gate 22. For this purpose, the hologram generator 60 has on its top a
window (not shown) for projecting a hologram, and said window is covered with a
transparent plate 106 forming a portion of the floor 93 of the gate 22.
The hologram generator 60 is adapted for giving different aspects to the hologram
62, depending on whether the user is prompted to show an access document (Fig. 17),
10 whether the crossing of the gate 22 is forbidden (Fig. 18)' whether the user has shown an
invalid access document (Fig. 19) or whether the user has shown a valid access
document (Fig. 20).
The compartments 40,50,64 are positioned under the gate 22 and are juxtaposed
to each other along the axis of the gate 22. The compartment 64 is at right angles to the
15 obstacle 62. The compartments 40, 50 are positioned on either side of the obstacle 62.
Each compartment 40, 50, 64 may be handled independently of the two other
compartments 40, 50, 64. It is thus possible to withdraw one of the compartments 40, 50,
64 from the cavity 42 while leaving the other compartments 40, 50, 64 in the cavity 42.
This gives the possibility of easily replacing the power supply module 24, the control
20 module 26 or the obstacle positioning device 28 without touching the other portions of the
monitoring device 20, or even suppressing the obstacle positioning device 28. The
monitoring device 20 thus has great modularity.
Alternatively (not shown), the power supply module 24, the control module 26 and
the obstacle positioning device 60 are housed in a same compartment, said compartment
25 for example being formed by the cavity 42.
Referring back to Figs. 1 to 3, the display device 30 comprises a plurality of
displays 110 positioned under the gate 22. In particular, each display 110 is positioned
above a respective compartment 40,50,64.
Each display 110 is positioned under the gate 93, which is transparent at right
30 angles to the display 110. Alternatively, each display 110 forms a portion of the flooring
93.
Each display 110 is for example a display of light-emitting diodes.
The display device 30 also comprises a module (not shown) for controlling the
displays 110. The controlling module is programmed so as to control the display, with the
35 displays 110, of information related to the availability of the gate 22, to the authorization or
to the prohibition of crossing the crossing 22, or to the signaling of an unauthorized
12
maneuver, such as a fraudulent attempt. Optionally, the controlling module is programmed
for controlling the display, with the displays 110, of messages of an informing nature, or of
advertising information, such as advertising videos.
With reference to Fig. 21, the information related to the availability of the gate 22 is
5 for example shown as a pictogram 112 illustrating a user showing an access document,
when the gate 22 is available, or a "no entry" panel 114 when the gate 22 is unavailable.
The information related to the authorization of passing through the gate 22 are for
example shown as green arrows 116 oriented in the direction of displacement of the user
having shown hislher access document. The information related to the signaling of an
10 unauthorized maneuver is for example shown as blinking 118 in an alarming color, such
as orange or red, of the whole of the display surface area of the displays 110.
Referring back to Figs. 1 to 3, the document reader 32 is positioned at one end,
along the axis of the gate 22, of the stringer 91 of one of the delimitation members 36, and
is oriented so as to face a user appearing at the entry of the gate 22. Alternatively, the
15 document reader 32 is oriented so as to show its profile to a user appearing at the entry of
the gate 22 (Fig. 22), or its tack (Fig. 23). Both of these last alternatives give the possibility
of limiting access to the document reader 32 only to the users already engaged into the
gate 22. This avoids that, in the case when two users appear subsequent to each other at
the entry of the gate 22, the second user does not show hislher access document before
20 the first user, which would has a consequence, an usurpation of the access document of
the second user by the first user and a blocking of the second user in the gate 22. The
flow of users through the gate 22 is thereby increased.
The document reader 32 is adapted for communicating with a contactless access
document. For this purpose, it comprises, with reference to Figs. 24 and 25, an antenna
25 122 and an electronic card 126. It further comprises a casing 120, a screen 124, a selfclamping
lock 127, a ferrite layer 128 and optionally a loudspeaker (not shown).
The casing 120 contains the antenna 122, the screen 124, the electronic card 126,
the loudspeaker, the self-clamping lock 127 and the ferrite layer 128. It has a window 130
at right angles to the screen 124, on one side of the casing 120 and, opposite to the
30 window 130, it bears a first hook 132 protruding from the casing 120 opposite to the
window 130. A foam layer 134 is preferably stuck, as illustrated, on the face of the casing
120 opposite to the window 130.
The antenna 122 is etched on a transparent and flexible substrate. It completes
one turn of the screen 124. By this positioning of the antenna 122, it is possible to show
35 the access document facing the screen 124.
13
The screen 124 is preferably flexible. For this purpose, the screen 124 is a screen
made in organic light-emitting diodes.
The electronic card 126 is electrically connected to the antenna 122. It is adapted
for reading and optionally writing data into the memory of a contactless media, for
5 example of the type CSC (Contactless Smart Card) or of the type NFC (Near Field
Communication), via the antenna 122. The electronic card 126 is also adapted for
communicating with the control module 26.
The ferrite layer 128 is interposed between the antenna 122 and any metal mass
which may interfere with the magnetic field generated by the antenna 122, for example the
10 stringer 91 or the electronic card 126. It is positioned behind the screen 124 in order not to
conceal it.
The loudspeaker is for example a flat and flexible loudspeaker, better known under
the acronym of FFL (Flat Flexible Loudspeaker).
The lock 127 comprises a return member, typically a torsional spring, adapted for
15 returning the lock 127 into a locking configuration. It is connected to a second hook 136
protruding form the same face of the casing 120 as the first hook 132, in the same
direction, so that the first and second hooks 132, 136 are curved towards each other. The
lock 127 is adapted for moving the second hook 136 away from the first hook 132 when it
is in an unlocking configuration, and for bringing the hooks 132, 136 closer when it is in a
20 locking configuration.
The document reader 32 is mounted on a support 138 secured to the stringer 91
so that the hooks 132, 136 clamp between them said support 138, the foam layer 134
being compressed between the casing 120 and the support 138.
Referring back to Figs. 1 to 3, the sensor 34 is positioned vertically above the gate
25 22. It is adapted for counting the number of users present in a detection area 140 of the
sensor 34, said area 140 being comprised in the gate 22. For this purpose, the sensor 34
for example comprises a TOF (Time Of Flight) camera observing the detection area 140.
The sensor 34 is adapted so as to communicate with the control module 26.
The sound emission member 38 is for example a loudspeaker. It is adapted for
30 communicating with the control module 26.
The control module 26 is programmed so as to infer, from the data read by the
document reader 32 into the memory of an access document, whether the user owner of
the access document is authorized to use the gate 22 or not. The control module 26 thus
forms, with the document reader 32, a system for authorizing circulation.
35 The control module 26 is also programmed for controlling the change in state of
the obstacle 62 and of the display device 30 depending on whether it was determined that
14
the user owner of the access document is authorized to use the gate 22 or not. In
particular, the control module 26 is programmed so as to control the displacement of the
movable members 70 in a retracted position and the display of information related to the
authorization of passing through the gate 22 by the displays 110 and by the screen 124
5 when it has been determined that the user owner of the access document is authorized to
use the gate 22, and for controlling the deployment of the movable members 70 and the
display of information related to the prohibition of passing through the gate 22 by the
displays 110 when it was determined that the user owner of the access document is not
allowed to use the gate 22. The control module 26 thus forms with the device for
10 obstruction of the gate 28, the display device on the ground 30 and the screen 124, a
signing system adapted for showing the user whether helshe is either authorized or not to
use the gate 22.
Moreover, the control module 26 is programmed so as to compare the data read
by the document reader 32 with the number of users detected by the sensor 34 and to
15 infer therefrom if required, a fraudulent attempt. In particular, the control module 26 is
programmed for counting a number of presentations, in a predetermined time interval, of
valid access documents to the document reader 32, in order to compare this number of
presentations with the number of users present in the area 140, and for inferring:
- absence of fraud when the number of presentations is greater than or equal to
20 the number of users, and
- a fraudulent attempt when the number of presentations is less than the number
of users.
The control module 26 thus forms, with the sensor 34, a fraud detection system.
Finally, the control module 26 is programmed for controlling the display of
25 information related to the signaling of an unauthorized maneuver by the displays 110, as
well as the emission of a sound alarm by the sound emission member 38, when it is
inferred that a fraudulent attempt is being accomplished. The control module 26 thus
forms, with the display device 32 and the sound emission member 38, an alarm system.
Always with reference to Fig. 1, the access control system 10 also comprises a
30 system 150 for ventilation of the cavity 42, a power supply cable 152 for electric
connection of each monitoring device 20 to an electricity network, and' a cable for
transferring data 154 for exchanging data between each monitoring device 20 and a
central data collection system (not shown).
The ventilation system 150 comprises an air suction system 160, positioned on the
35 outside of the cavity 42, and a ventilation conduit 162 fluidically connecting the air suction
15
system 160 to the cavity 42. The ventilation system 150 also comprises a plurality of air
intakes 164 for entering air into the cavity 42.
The suction system 160 is a conventional air suction system and will not be
described here.
5 The ventilation conduit 162 extends through one of the fixed obstacles 16. It forms
a grommet for the power supply cables 152 and the data transfer cables 154.
Each air intake 164 is formed with an air intake orifice formed in one of the
delimitation members 36 of each monitoring device 20 and which is in fluidic
communication with the cavity 42. Thus, the air entering the cavity 42 is taken in height,
10 which allows better renewal of the air inside the cavity 42. For this purpose, the post 90 of
said delimitation member 36 is preferably hollow.
The power supply cable 152 is electrically connected to the socket 44 of the
compartment 40 of each monitoring device 20.
The access control system 1000, illustrated in Figs. 26 to 29, is intended to control
15 the entry of users into a restricted area 1012. Alternatively, the access control system
1000 is intended to exclusively control the exit, or the entry and the exit of users in the
restricted area 101 2.
For this purpose, the access control system 1000 comprises a plurality of
monitoring devices 1020 juxtaposed to each other so as to isolate the restricted area 1012
20 of a free area 1014, any user passing from the restricted area 1012 to the free area 1014
necessarily having to use a pedestrian gate 1022 specific to one of the monitoring devices
1020.
The restricted area 1012 is typically an inside space of a building, a common
transportation network, or an amusement park. It is reserved for the possessors of a valid
25 access document.
Each monitoring device 1020 is adapted for monitoring the entry into the restricted
area 1012 of users using the pedestrian gate 1022 specific to the monitoring device 1020.
Alternatively, each monitoring device 1020 is adapted for exclusively controlling the exit,
or the entry and exit of users passing through the pedestrian gate 1022.
30 By "pedestrian" gate, it is understood that each gate 1022 is adapted for the
passing of a pedestrian, preferably an armchair pedestrian, and of hislher luggage, but not
of an automobile. For this purpose, each gate 1022 typically has a width comprised
between 40 cm and 80 cm.
Each monitoring device 1020 comprises a power supply module 1024, a control
35 module 1026, a passage 1022 obstruction device 1028 specific to the monitoring device
1020, two members 1036 for delimiting lateral edges of the gate 1022, a sensor 1034, and
16
a device for interacting with the user comprising a display device 1030, a document
reader 1032 and a sound emission member 1038 (Fig. 31).
The power supply module 1024 is adapted for shaping an electric current for
powering the monitoring device 1020, so as to provide a stable electrical power supply
5 without any cutoffs with the remainder of the monitoring device 1020. This type of power
supply module is known and is generally designated under the name of interruption-free
power supply, or UPS (Uninterruptible Power Supply).
The power supply module 1024 is housed in a first compartment 1040 positioned
in a cavity 1042 extending above the gate 1022 specific to the monitoring device 1020. In
10 the illustrated example, the cavity 1042 is common to all the monitoring devices 1020 and
extends above all the gates 1022.
The cavity 1042 is in particular formed by the inside of a hollow beam 1043
positioned above the gate 1022 and oriented transversely to said gate 1022. In the
illustrated example, this hollow beam 1043 has a substantially trapezoidal section with
15 rounded angles.
With reference to Fig. 30, the compartment 1040 contains, in addition to the power
supply module 1024, an outlet 1044 for connecting to an electricity network powering the
access control system 1000, an exit socket 1046 for the shaped electric current, and a
maintenance socket 1048, the power supply module 1024 being electrically connected to
20 each of the sockets 1044, 1046, 1048.
Referring back to Figs. 26 to 29, the control module 1026 is a computer, for
example an industrial computer adapted so as to be powered with a 12 V voltage. It has
means (not shown) for communicating with the obstruction device 1028, the display
device 1030, the document reader 1032, the sensor 1034 and the sound emission
25 member 1038.
The control module 1026 is housed in a second compartment 1050 positioned in
the cavity 1042.
With reference to Fig. 31, said compartment 1050 contains, in addition to the
control module 1026, a power supply socket 1052 electrically connected to the output
30 socket 1042 of the compartment 1040, a maintenance socket 1054, a transformer 1056
for adapting the provided current to the power supply socket 1052 to the power supply
voltage of the control module 1026, a keyboard 1058, for programing the control module
1026, and the sound emission member 1038.
Each delimitation member 1036 is common to the monitoring device 1020 and to
35 one of the monitoring devices 1020 which is adjacent to it, except in the cases when the
monitoring device 1020 is only juxtaposed to a single other monitoring device 1020, in
17
which case only one of the delimitation members 1036 is common to the monitoring
device 1020 and to a monitoring device 1020 which is adjacent to it.
Each delimitation member 1036 comprises a post 1090 and optionally, a stringer
1091. The post 1090 is oriented substantially vertically. The stringer 1091 is oriented
5 substantially horizontally, parallel to the axis of the gate 1022. The stringer 1091 is at a
distance from the floor 1093 of the gate 1022, and is borne by the post 1090.
Each post 1090 preferably has, as illustrated in Fig. 39, an elongated horizontal
section parallel to the axis of the gate 1022.
Each post 1090 supports the hollow beam 1043.
10 Each post 1090 is preferably in steel.
With reference to Figs. 40 and 41, each post 1090 is held on the ground by two
attachment devices 1098. These attachment devices 1098 are positioned on either side of
the post 1090 along the axis of the gate 1022. Each attachment device 1098 is secured to
a lower end of the post 1090.
15 Each attachment device 1098 is preferably in steel.
Each attachment device 1098 comprises two flanges 1100 forming between them
an angle comprised between 90" and 160°, and a plate 1102 connecting the flanges 1100
to each other.
Each flange 1100 is oriented substantially vertically, and the plate 1102 is oriented
20 substantially horizontally. The flanges 1100 converge towards the post 1090. This
configuration of the attachment device 1098 allows good transmission of the forces
exerted on the post 1090, along the axis of the gate 22, towards the ground. The
resistance of the post 1090 to detachment is thus increased.
The plate 1102 has a plurality of orifices 1104 for letting through attachment
25 members (not shown), for example screws, for attaching the plate 1102 to the ground.
The attachment devices 1098 are positioned on the ground.
Referring back to Figs. 26 to 29, the obstruction device 1028 comprises an
obstacle positioning device 1060, suitable for positioning an obstacle 1062 across the
gate 1022 specific to the monitoring device 1020. This obstacle positioning device 1060 is
30 housed in a third compartment 1064 positioned in the cavity 1042.
With reference to Fig. 32, the compartment 1064 contains, in addition to the
obstacle positioning device 1060, a power supply socket 1065 electrically connected to
the output socket 1042 of the compartment 1040, a maintenance socket 1066, and an
electric converter 1068 for converting the current provided to the power supply socket
35 1065 into a current suitable for powering the obstacle positioning device 1060.
18
According to a first exemplary embodiment of the second embodiment of the
invention, illustrated in Figs. 32 to 41, the obstacle 1062 comprises at least one movable
member 1070 between a deployed position, in which it extends through the gate 1022,
and a retracted configuration, in which it is disengaged from said gate 1022, and the
5 obstacle positioning device 1060 is formed by an actuator mechanically connected to said
or each movable member 1070 for driving it between its deployed configuration and its
retracted configuration.
In the illustrated example, the obstacle 1062 is formed with two movable members
1070, said movable members 1070 being barriers. Alternatively, the movable members
10 1070 are gates.
Each barrier 1070 is adapted so as to be oriented horizontally and perpendicularly
to the axis of the gate 1020 when it is in a deployed configuration, and:
- according to a first alternative, illustrated in Figs. 37 to 40, in order to be
oriented parallel to the axis of the gate 1020 when it is in a retracted
15 configuration, or
- according to a second alternative, illustrated in Fig. 41, in order to be oriented
vertically when it is in a retracted configuration.
The actuator 1060 is an electric motor, for example a servomotor with variable
speed. Preferably it has as many output shafts 1080 as there are movable members
20 1070. In the illustrated example, the actuator 1060 thus has two output shafls 1080.
Alternatively, the obstacle 1062 is formed with a single movable member 1070, for
example a gate, and the actuator 1060 then has a single output shafl 1080.
With reference to Fig. 33, the mechanical connection between the actuator 1060
and each movable member 1070 comprises an intermediate shaft 1072, substantially
25 oriented horizontally and perpendicularly to the axis of the gate 1022, an obstacle shaft
1074, oriented substantially vertically, a first device 1076 for coupling the obstacle shaft
1074 to the intermediate shaft 1072, and a second device 1078 for coupling the obstacle
shaft 1074 to the movable member 1070.
The intermediate shafl 1072 is secured in rotation around its axis of an output shaft
30 1080 of the actuator 1060. In the illustrated example, the output shaft 1080 defines a
cavity 1082 for receiving the intermediate shaft 1072, and the coupling of the output shaft
1080 with the intermediate shaft 1072 is achieved by cooperation of a rib 1084 (Fig. 36)
protruding radially from a wall of the cavity 1082 with an axial groove 1086 (Fig. 35) made
in the intermediate shaft 1072. Referring back to Fig. 33, a compression spring 1088 is
35 positioned in the cavity 1082 and presses against a bottom (not shown) of the cavity ,082
and against an end 1089 of the intermediate shaft 1072 so as to push the shaft 1072
19
outside the cavity 1082. This gives the possibility of facilitating the installation of the
obstruction device 1028
The obstacle shaft 1074 borders the post 1090 of one of the delimitation members
1036 of the monitoring device 1020.
5 The first coupling device 1076 is adapted so that the rotation of one of the shafts
1072, 1074 around its axis causes rotation of the other shaft 1072, 1074 around its axis.
For this purpose, the first coupling device 1076 is for example an angled gearbox such as
the gearbox slide-RiteTMfr om Tolomatic.
According to the alternative of Figs. 37 to 40, the second coupling device 1078 is a
10 clamping ring, secured to the movable member 1070 and clamped around the obstacle
shaft 1074. The movable member 1070 and the obstacle shaft 1074 are thus secured in
rotation around the axis of the obstacle shaft 1074.
In order to rigidify the obstacle shaft 1074, the post 1090 bordered by said shaft
1074 then bears, at its lower end, a shoe 1092 (Fig. 40) defining an orifice 1094 for
15 receiving an upper end 1096 of said obstacle shaft 1074. Thus, the obstacle shaft 1074 is
held at its lower and upper ends, which avoids its flexing.
The shoe 1092 is in particular interposed between the devices 1098 for attaching
the beam 1090, as illustrated in Fig. 40.
According to the alternative of Fig. 41, the second coupling device 1078 is adapted
20 so that the rotation of the obstacle shaft 1074 around its axis causes rotation of the
movable member 1070 around an axis substantially parallel to the axis of the gate 1022.
For this purpose, the second coupling device 1078 is for example an angled gearbox like
the gearbox slide-RiteTMfr om Tolomatic.
In order to rigidify the obstacle shaft 1074, the second coupling device 1078 is
25 secured to the post 1090 bordered by said shaft 1074. Thus, the obstacle shaft 1074 is
held at its lower and upper ends which avoids its flexing.
The intermediate shafts 1072 are transversely aligned with each other. In other
words, the axes of the intermediate shafts 1072 are comprised in a same vertical plane.
The obstacle shafts 1074 are transversely aligned with each other. In other words,
30 the axes of the obstacle shafts 1074 are comprised in a same plane perpendicular to the
axis of the gate 1022.
According to a second exemplary embodiment of the second embodiment of the
invention, illustrated in Figs. 42 to 45, the obstacle 1062 is a hologram, and the obstacle
positioning device 1060 is a hologram generator.
35 The hologram generator 1060 is adapted so as to generate the hologram 1062 so
that it extends across the gate 1022. For this purpose, the hologram generator 1060 has
20
on its unders~dea window (not shown) for projecting a hologram, and the hollow beam
1043 comprises a transparent portion 1106 extending facing said window.
The hologram generator 1060 is adapted so as to give various aspects to the
hologram 1062, according to whether the user is prompted to show an access document
5 (Fig. 42), whether the crossing of the gate 1022 is forbidden (Fig. 43), whether the user
has shown an invalid access document (Fig. 44) or whether the user has presented aa
valid access document (Fig. 45).
The compartments 1040, 1050, 1064 are positioned above the gate 1022 and are
juxtaposed to each other along the axis of the gate 1022. The compartment 1064 is at
10 right angles to the obstacle 1062. The compartments 1040, 1050 are positioned on either
side of the obstacle 1062.
Each compartment 1040, 1050, 1064 may be handled independently of the two
other compartments 1040, 1050, 1064. It is thus possible to withdraw one of the
compartments 1040, 1050, 1064 of the cavity 1042 while leaving the other compartments
15 1040, 1050, 1064 in the cavity 1042. It is also possible to switch the compartments 1040
and 1050, either upwards or downwards, thus allowing access to them without
disassembling the beam 1043 for carrying out maintenance, this switching thus also
releasing an access without disassembling to the compartment 1064, on either side of the
latter. This allows easy replacement of the power supply module 1024, the control module
20 1026 or the obstacle positioning device 1028 without touching the other portions of the
monitoring device 1020, or even suppressing the obstacle positioning device 1028. The
monitoring device 1020 thus has great modularity.
Alternatively (not shown), the power supply module 1024, the control module 1026
and the obstacle positioning device 1060 are housed in a same compartment, said
25 compartment for example being formed with the cavity 1042.
Referring back to Figs. 26 to 29, the display device 1030 comprises a plurality of
displays 11 10 positioned above the gate 1022. In particular, each display 11 10 is affixed
on an external face of the hollow beam 1043.
Each display 1110 is for example a display with light-emitting diodes or backlit
30 liquid crystals.
In the illustrated example, the display device 1030 also comprises a projector 11 11
(Fig. 32) for projecting an image on a projection surface formed by the flooring of the gate
1022 or by a surface of a delimitation member 1036. This projector 1111 is preferably
housed in the compartment 1064, as illustrated in Fig. 32. The hollow beam 1043 then
35 comprises a transparent portion 1106 extending below the compartment 1064.
21
The display device 1030 also comprises a module (not shown) for controlling the
displays 11 10 and the projector 1111. The controlling module is programed so as to
control the display, with the displays 1110 and/or with the projector 11 11, of information
related to the availability of the gate 1022, to the authorization or to the prohibition of
5 passing through the gate 1022, or to the signaling of an unauthorized maneuver, such as
a fraudulent attempt. Optionally, the controlling module is programed for controlling the
display, with the displays 1110 and/or with the projector 1111, of messages of an
informative nature, or advertising information, such as advertising videos or information on
the traffic.
10 With reference to Fig. 46, the information related to the availability of the gate 1022
is for example shown as a pictogram 1112 illustrating a user showing an access
document, when the gate 1022 is available, or a "no entry" panel 1114 when the gate
1022 is unavailable. The information related to the authorization of passing through the
gate 1022 are for example shown as green arrows 1116 oriented in the direction of
15 displacement of the user having shown hislher access document. The information related
to the signaling of an unauthorized maneuver are for example shown as a blinking 11 18 in
an alarming color, such as orange or red, of the entirety of the display surface area of the
displays 11 10 and/or of the projection surface of the projector 11 11.
Referring back to Figs. 26 to 29, the document reader 1032 is positioned at one
20 end, along the axis of the gate 1022, of the stringer 1091 of one of the delimitation
members 1036, and is oriented so as to face a user appearing at the entry of the gate
1022. Alternatively, the document reader 1032 is oriented so as to show its profile to a
user appearing at the entry of the gate 1022 (Fig. 47), or its back (Fig. 48). Both of these
last alternatives give the possibility of limiting access to the document reader 1032 to the
25 sole users already engaged in the gate 1022. This avoids that, in the case when two users
appear subsequently to each other at the entry of the gate 1022, the second user does
not show hislher access document before the first user, which would have the
consequence of usurpation of the access document of the second user by the first user
and blocking of the second user in the gate 1022. The flow of users through the gate 1022
30 is thereby increased.
The document reader 1032 is adapted for communicating with a contactless
access document. For this purpose, the document reader 1032 is identical with the
document reader 32.
The sensor 1034 is positioned vertically above the gate 1022. It is adapted for
35 counting the number of users present in a detection area 1140 of the sensor 1034, said
area 1140 being comprised in the gate 1022. For this purpose, the sensor 1034 for
22
example comprises a Time Of Flight camera (TOF camera) observing the detection area
1140.
The sensor 1034 is adapted for communicating with the control module 1026.
The sound emission member 1038 is for example a loudspeaker. It is adapted for
5 communicating with the control module 1026.
The control module 1026 is programed for inferring, from the data read by the
document reader 1032 into the memory of an access document, whether the user owner
of the access document is authorized to use the gate 1022 or not. The control module
1026 thus forms, with the document reader 1032, a system for authorization of circulation.
10 The control module 1026 is also programmed for controlling the change of state of
the obstacle 1062 and of the display device 1030 according to whether it was determined
that the user owner of the access document is authorized to use the gate 1022 or not. In
particular, the control module 1026 is programmed for controlling the displacement of the
movable members 1070 in a retracted position and the display of information related to
15 the authorization of passing through the gate 1022 by the displays 1110, by the projector
11 11 and by the screen 124 when it was determined that the user owner of the access
document is authorized to use the gate 1022, and for controlling the deployment of the
movable members 1070 and the display of information related to the prohibition of passing
through the gate 1022 by the displays 11 10 and by the projector 111 1 when it was
20 determined that the user owner of the access document is not authorized to use the gate
1022. The control module 1026 thus forms, with the device for obstruction of the gate
1028, the display device on the ground 1030 and the screen 124, an adapted signing
system for informing the user whether helshe is either authorized or not to use the gate
1022.
25 Moreover, the control module 1026 is programmed for comparing the data read by
the document reader 1032 with the number of users detected by the sensor 1034 and for
inferring therefrom, if necessary, a fraudulent attempt. In particular, the control module
1026 is programmed for counting a number of presentations, within a predetermined time
interval, of valid access documents to the document reader 1032, in order to compare this
30 number of presentations with the number of users present in the area 1140, and for
reducing:
- an absence of fraud when the number of presentations is greater than or equal
to the number of users, and
- a fraudulent attempt when the number of presentations is less than the number
of users.
23
The control module 1026 thus forms, with the sensor 1034, a fraud detection
system.
Finally, the control module 1026 is programmed for controlling the display of
information related to the signaling of an unauthorized maneuver by the displays 11 10 and
5 by the projector 11 11, as well as the emission of a sound alarm by the sound emission
member 1038, when it is inferred that a fraudulent attempt is being carried out. The
control module 1026 is also programmed for controlling the illumination of the fraudster by
the projector 1026 when it is inferred that a fraudulent attempt is being carried out. The
control module 1026 thus forms, with the display device 1032 and the sound emission
10 member 1038, an alarm system.
Always with reference to Fig. 27, the access control system 1000 also comprises a
system 1150 for ventilation of the cavity 1042, a power supply cable 1152 for electrically
connecting each monitoring device 1020 to an electricity network, and a data transfer
cable 1154 for exchanging data between each monitoring device 1020 and a central data
15 collection system (not shown).
The ventilation system 1150 comprises an air suction or injection system 1160,
positioned on the outside or inside the cavity 1042, in fluidic communication with the cavity
1042. The ventilation system 1150 also comprises a plurality of air intakes 1164 for the
entry or exit of air in the cavity 1042. Each air intake 1164 is preferably provided with a
' 20 removable filter (not shown) intended to avoid accumulation of dust in the cavity 1042.
The suction or injection system 1160 is a standard air injection or suction system
and will not be described here.
Each air intake 1164 is formed by an air intake orifice formed in a wall of the hollow
beam 1043. Thus, the air entering the cavity 1042 is taken in height, which allows better
25 renewal of the air inside the cavity 1042.
The power supply cable 1152 is electrically connected to the socket 1044 of the
compartment 1040 of each monitoring device 1020.
By means of the invention described above, the size of each of the monitoring
devices 20, 1020 is reduced. A larger number of monitoring devices 20, 1020 is thus
30 juxtaposed in a same space, and thus the pedestrian flow who may pass through said
space is thereby increased.
Further, each access control system 10, 1000 has great modularity in so far that it
is easy to replace a compartment 40, 50, 64, 1040, 1050, 1064 of one of the monitoring
devices 20, 1020 independently of the other compartments 40, 50, 64, 1040, 1050, 1064
35 of said monitoring device 20, 1020.

Finally, a s the shape o f the delimitation members 36, 1036 is no longer
constrained by the requirement of protecting the equipment present inside, it is possible to
produce delimitation members of various shapes and adapted to the environment in which
the access control system 10, 1000 is used. It is also possible to use for these delimitation
5 members non-conventional materials.
It will be noted that, although the invention has been described as two
embodiments distinct from each other, the invention also extends to any combination of
these two embodiments. Thus, the object of the invention is also any access control
system mixing the features of both embodiments described earlier, according to any
10 technically possible combination of features. Thus, the object of the invention is notably an
access control system in which only a portion of the power supply modules, control
module and obstacle positioning device will be housed under the gate, the remainder of
said power supply module, control module and obstacle positioning device being housed
above the gate.
