FIELD OF THE INVENTION
Embodiments of the present invention generally relates to
technologies involving maintenance of lighting systems and more
particularly to an unmanned aerial vehicle (UAV) and a system for
5 monitoring and maintaining luminaires using the UAV.
BACKGROUND OF THE INVENTION
Electronic devices such as luminaires etc. often need to be assessed
for performance, serviced for effective working, repaired or replaced. This
becomes a bit problematic and time taking when it comes to luminaires
10 mounted on long/high poles. The presently available solution is totally man
operated and is very risky for the service personnel to work at such a unsafe
height. When it comes to replacement of the complete luminaire the
currently adopted procedure of lifting the personnel up to the height of the
faulty luminaire seems to be effective but in case of assessing and finding
15 the problematic area or parts, one needs to spend time up there and that is
really dangerous. Unmanned Aerial Vehicles (UAV) have emerged as one
of the most exciting prospects for futuristic innovations. New applications
using the UAVs are gaining popularity rapidly. Some of the applications
utilize hovering capabilities of UAVs to reach places where it is difficult for a
20 human to be present, be it for monitoring or service and maintenance work.
Recently, the UAVs have been utilized for servicing work of electronic
devices such as luminaires. This has proved beneficial for humans who do
not have to risk their life for replacing luminaires. Though the existing
methods/systems strive to provide solutions to the problem discussed
25 above, however, most or all of them come with a number of limitations or
shortcomings. The replacement work only requires removal of the faulty
luminaire and placement of the new one. But presently none of the available
solutions accomplish the performance test as well as repair work. In case
the failure isn’t related to the installed luminaire, the UAVs replacing the
3
luminaire won’t solve the problem. Problem may be in the electronic setup
around the luminaire and problems such as over voltage, under voltage,
burn-out of feeder supply wires etc. require testing first. But existing systems
and UAVs are not able to solve the problem and for such problems, human
5 worker is required to risk his life.
Therefore, there remains a need in the art for an unmanned aerial
vehicle (UAV) and a system for monitoring and maintaining luminaires using
the UAV, that does not suffer from above mentioned deficiencies or at least
provides a viable and effective solution.

of the one or more luminaires (190n) based on the respective plurality of
first values received, thereby providing an information about the working
25 condition of the one or more luminaire (190n).
In this regard, the light module (1901) is envisaged to include
processing capabilities. The light module (1901) is envisaged to include prestored ideal values of the one or more parameters. The pre-stored values
may be compared with the measured values of the one or more parameters
10
to determine the working condition of the one or more luminaires (190n).
For example: if pre-stored ideal value of the voltage is 220V and the
measured value is 250V, then the light module (1901) would determine the
luminaire to be in the faulty condition (overvoltage).
5 The system (100) further comprises a computing device (140). The
computing device (140) is placed in a control room (110) (at a central
location) and is connected with the one or more luminaires (190n) using a

25 signals from the remote controller (170) and transmitting them to the flight
controller (1605), a battery and battery charger (1610) to power the UAV
(160).
The UAV (160) shown in figure 2, further comprises a second
plurality of sensors (1608), one or more robotic arms (1604), an image
12
capturing device (1609) and testing module (1611). These are used to
detect and identify one or more issues with the one or more luminaires
(190n) indicative of a working condition of the one or more luminaires
(190n). The working condition may be a normal working condition or a faulty
5 condition caused by the one or more issues. The one or more issues may
be, but not limited to, luminaire malfunction/replacement, undervoltage
condition, overvoltage condition, leakage of current, high/low energy
consumption, scheduled maintenance and circuit malfunction etc. The
second plurality of sensors (1608) may include, but not limited to, 3 axis
10 accelerometer, 3-axis gyroscope, Magnetometer, Barometer, GPS Sensor,
Distance Sensor, Infrared sensor, permanent magnets and magnetic field
sensor. The one or more robotic arms (1604) are capable of the carrying

holding means such as a claw (not shown in figure 2) at a free end of the
15 one or more arms. The testing module (1611) may include one or more of,
but not limited to, ammeter, voltmeter, multi-meter, clamp-meter, power
meter, oscilloscope, function generator or other instrument capable of

20 the parameters (such as a weight, a discharge rate, a voltage of the UAV
(160)), a tracking module (1602), a storage module and an information
module. The communication module (1603) is configured to act as a honey
pot, comprising one or more transmitters to provide open Wi-Fi network for
a user. The tracking module (1602) may include, but not limited to, wireless

further comprise artificial intelligence and machine learning based
30 technologies, but not limited to, for data analysis, collating data,
13
presentation of data in real-time.
Figure 3A illustrates an information flow diagram of the system (100)
for monitoring luminaires (190), using UAV (160), in accordance with an
embodiment of the present invention. As shown in figure 3, the first plurality
5 sensors (1902) of a luminaire (190) of the one or more luminaires (190n),
generate a respective plurality of first values, indicative of a first one or more
parameters of the luminaire (190). The light module (1901) is configured to
receive the plurality of first values and determine the first one or more
parameters of the luminaire (190n). After comparison with pre-stored ideal
10 parameters, the light module (1901) generates an information about the
working condition of the one or more luminaires. For example, the light
module (1901) may determine the luminaire (190) to be in faulty condition
(over voltage, under voltage, overheat etc.) or normal condition (working
fine).
15 In system (100), the one or more luminaires (190n) are in
communication with the computing device (140). So, the respective light
modules of each of the one or more luminaires (190n) communicate the
working condition of each of the one or more luminaires (190n) to the
computing device (140). The processor (130) receives the information about
20 the working condition of the one or more luminaires (190n) being normal or
faulty. According to the information received, the processor (130) identifies
the location/locations of one or more faulty luminaires. For the sake of
explanation, it is envisaged that only one luminaire (190) is determined to
be faulty.
25 Accordingly, the processor (130) is configured to generate a
command or direct a UAV (160) of one or more UAVs (160n) to reach a
location of the faulty luminaire (190) by using tracking module (1602). The
UAV (160) is then instructed to diagnose and identify the issue with faulty
luminaire (190). In one embodiment, the UAV may directly connect with the
14
light module upon reaching the location of the faulty UAV (190) to know the
determined one or more issues. In another embodiment, the UAV (160) may
itself diagnose and identify the one or more issues by accessing the
electronic circuit and components of the faulty luminaire (190) using the
5 second plurality of sensors and the robotic arms and claws.
For example: the testing module (1611) is used to test electrical
connection/parameters of the luminaire (190), the image capturing device
(1609) (such as a camera) may capture the visual environmental condition
around the luminaire (190), the second plurality of sensors (1608) may be
10 used to determined the second one or more parameters of faulty luminaire
(190) and transmit details of a sensed and tested parameters to processing
module (1601) of the UAV (160). The second one or more parameters may
include, but not limited, temperature, voltage, current, moisture, luminaire
malfunction. According to the sensed and tested parameters, the
15 processing module (1601) used to identify the one or more issues of the
faulty luminaire (190).
After identifying one or more issue in the faulty luminaire (190). The
processing unit (1601) provides the command to rectify the identified the
one or more issues in the faulty luminaire (190) using the one or more
20 robotic arms. For example: In case there is a circuit malfunction, then the
UAV (160) may be directed to test and repair the electronic circuit. In case,
there is a damage caused to the luminaire due to over-voltage, over-heating
etc., then the UAV (160) may be directed to find the problematic
components causing the fault, rectify the problem and replace the
25 luminaire/problematic components (if required). In case, if the issues are
caused by the accumulation of dust, then the UAV (160) is envisaged to
clean the circuitry and surroundings of the faulty luminaire (190).
Figure 4 illustrates a pictorial representation of the implementation
Unmanned Aerial Vehicle (UAV) (160) being used for monitoring and testing
15
a luminaire, in accordance with an embodiment of the present invention. As
shown in figure 4, the luminaire (190) is mounted on a Pole (510). The
luminaire (190) may be solar powered and one or more solar panels (540)
may be connected with the luminaire (190) and mounted on the Pole (510).
5 In one embodiment, the UAV (160) may also assist in cleaning and/or
replacing the solar panels from time to time or when required. Additionally,
the artificial intelligence and the machine learning technologies enable the
UAV (160) to learn several new electronic lighting systems/circuits, the
assemblies and the overhauling methods.
10 In another embodiment, the UAV (160) further comprises one or
more attachment pads for easy attachment and detachment of the luminaire
sensors (1902). Using a small control board with blue tooth radio to power
attachment pads on the UAV(190) and operate in conjunction with the UAV
(160) that is delivering or retrieving the sensor from the luminaire (190). The
15 attachment pad would be an electro-magnetic surface that is always
powered. When a drone delivers a sensor for the first time it would
automatically attach without communication between the UAV (160) and the
luminaire 190’s light module (1901). If the sensor needs to be retrieved, the
UAV 160 would issue a blue tooth command to the light module (1901) to
20 turn off the power for a predetermined time, say 3 mins, long enough for the
UAV 160 to grab the sensor and fly away.
In another embodiment, the communication module of the UAV (160)
also comprises one or more transmitters (550) creating an open Wi-Fi
network for users to connect and act as a honey pot. In general, a honey
25 pot is set up to act as a decoy to lure cyber attackers, and to detect, deflect
or study attempts to gain unauthorized access to information systems. It is
well known that open access networks are preferred for cyber-attacks. This
will provide an advantage of monitoring cyber activity of potential hackers
and prevent cyber crimes as the network coverage of drone will be much
16
more than the conventional honey pots. In case of detection of any illegal
activity over the Wi-Fi network, the computer system may easily trap the
cyber attacker and also inform the law enforcement authorities.
In yet another embodiment, the computer device (140) may be
5 configured to receive the notification as soon as a luminaire (190) and the
automatically the coordinates of the location of the luminaire (190) are sent
to the UAV (160) nearest to the location, thereby automating the whole
process.
The present invention offers a number of advantages. Firstly, the
10 present invention widens the scope of the UAVs to the luminaire testing and
servicing. Unlike presently available systems and devices the present
invention can be used to find/identify the problem in a luminaire set up or
perform a simple testing check to ensure all the components of the
electronic set up around the luminaire are working fine. It is advantageous
15 as testing and servicing is time consuming and requires human workers to
reach the luminaire and stay high up there risking their life, to test and repair
the circuitry around the luminaire.
In general, the word “module,” as used herein, refers to logic
embodied in hardware or firmware, or to a collection of software instructions,
20 written in a programming language, such as, for example, Java, C, Python
or assembly. One or more software instructions in the modules may be

computer-readable medium or other computer storage device.
Further, one would appreciate that a communication network may
also be used in the system. The communication network can be a short-
17
range communication network and/or a long-range communication network,
wire or wireless communication network. The communication interface
includes, but not limited to, a serial communication interface, a parallel
communication interface or a combination thereof. The communication is
5 established over may be, but not limited to, wired network or wireless
network such as GSM, GPRS, CDMA, Bluetooth, Wi-fi, Zigbee, Internet,
