BACKGROUND
[0002] Background description includes information that may be useful in understanding the
present invention. It is not an admission that any of the information provided herein is prior art or
relevant to the presently claimed invention, or that any publication specifically or implicitly
referenced is prior art.
[0003] Elevators installed in the malls, hospitals and educational institutes and other
organizations reduces a lot of human effort. However, elevators have certain protocols of
working, and accordingly they function. Generally, they have operational panels with switches
bearing numbers and some other switches for opening and closinggate of the elevator voluntarily
as requested by humans.Sometimes there can arise a situation, when human is there on
stretcheroutside elevator on a floor to be shifted urgently to some other floor for immediate
treatment. However, elevator arrives at that floor as per its protocol of working. That is if
elevatoris currently going up at a requested level by human and situation of emergency arises at
an another level, the elevator will go at requested level and then it will come at another level
with emergency situation.
[0004] In such cases, there are chances of risk related to life of humans or danger. Also in
some situation, two humans standing at different levels with different designation request for
elevator, however according to working protocols of conventional elevator, the elevator goes to
level who requests it first. This further causes time wastage of human with high designation and
delay in their work. In certain conditions, humans with facial expression showing urgency for
elevator dispatch is seen, however again conventional elevator follows working protocols and
elevator is dispatched at requested level irrelevant of needs and urgency of humans. Difficulties
and inconvenience caused due to conventional elevators need to be resolved by bringing
elevators which handles situations described above intelligently.
3
[0005] There is a need to overcome the above mentioned problems by providing a solution,
which can identify emergency situationsmartly and automatically during elevator dispatching
and accordingly operates for the humans with emergency situation and is very easily managed
and installed.

102-2, 102-3 can be configured to capture array of images, wherethe array of images can be
transferred to the central controller. The central controller can include machine learning
algorithms that facilitates in identifying the situation of emergency.
[0077] In an illustrative embodiment, the image acquisition unit 102-1, 102-2, and 102-3
configured at the first level 302-1, second level 302-2, and the third level 302-3 can facilitate in
capturing the array of images from the first level 302-1, second level 302-2, and the third level
302-3. In another illustrative embodiment, an entity with medical emergency can wait on the first
16
level 302-1, for the elevator dispatch, and an another entity without medical emergency can wait
on the second level 302-2. The image acquisition unit 102-1 positioned at the first level 302-1
can be configured to capture the image pertaining to medical emergency and the image
acquisition unit 102-2 positioned at the second level 302-2 can be configured to capture the
image pertaining to no medical emergency. The image acquisition unit 102-1 and 102-2 can
transfer the image pertaining to medical emergency associated with the entity, where the image
pertaining to the medical emergency can be predefined priority stored in a database 210 of the
system 100, and the image pertaining to no medical emergency to the raspberry –pi. The
raspberry -pi can facilitate in identifying the image pertaining to the medical emergency and can
enable control unit 104 in dispatching the elevator at first level 302-1 with medical emergency.
[0078] In an illustrative embodiment, the predefined priority can be configured to be updated
based on the priority of the each of the detected one or more entities.In another illustrative
embodiment, the raspberry - pi can be configured to generate a set of alarm signals, when the
control unit 104 enables the movement of the elevator at a level other than the requested level.
The set of alarm signals can be provided using a siren, speaker, and illuminated light emitting
diode (led).
[0079] In an illustrative embodiment, the device can include a power source configured to
supply electric power to the device. In another illustrative embodiment, the power source can
includeany or a combination of battery, inverters, generators, power lines, and electric lines.
[0080] Thus, it will be appreciated by those of ordinary skill in the art that the diagrams,
schematics, illustrations, and the like represent conceptual views or processes illustrating
systems and methods embodying this invention. The functions of the various elements shown in
the figures may be provided through the use of dedicated hardware as well as hardware capable
of executing associated software. Similarly, any switches shown in the figures are conceptual
only. Their function may be carried out through the operation of program logic, through
dedicated logic, through the interaction of program control and dedicated logic, or even
manually, the particular technique being selectable by the entity implementing this invention.
Those of ordinary skill in the art further understand that the exemplary hardware, software,
processes, methods, and/or operating systems described herein are for illustrative purposes and,
thus, are not intended to be limited to any particular named.
17
[0081] While embodiments of the present invention have been illustrated and described, it
will be clear that the invention is not limited to these embodiments only. Numerous
modifications, changes, variations, substitutions, and equivalents will be apparent to those skilled
in the art, without departing from the spirit and scope of the invention, as described in the claim.
[0082] In the foregoing description, numerous details are set forth. It will be apparent,
however, to one of ordinary skill in the art having the benefit of this disclosure, that the present
invention may be practiced without these specific details. In some instances, well-known
structures and devices are shown in block diagram form, rather than in detail, to avoid obscuring
the present invention.
[0083] As used herein, and unless the context dictates otherwise, the term "coupled to" is
intended to include both direct coupling (in which two elements that are coupled to each other
contact each other) and indirect coupling (in which at least one additional element is located
between the two elements). Therefore, the terms "coupled to" and "coupled with" are used
synonymously. Within the context of this document terms "coupled to" and "coupled with" are
also used euphemistically to mean “communicatively coupled with” over a network, where two
or more devices are able to exchange data with each other over the network, possibly via one or
more intermediary device.
[0084] It should be apparent to those skilled in the art that many more modifications besides
those already described are possible without departing from the inventive concepts herein. The
inventive subject matter, therefore, is not to be restricted except in the spirit of the appended
claims. Moreover, in interpreting both the specification and the claims, all terms should be
interpreted in the broadest possible manner consistent with the context. In particular, the terms
“comprises” and “comprising” should be interpreted as referring to elements, components, or
steps in a non-exclusive manner, indicating that the referenced elements, components, or steps
may be present, or utilized, or combined with other elements, ` components, or steps that are not
expressly referenced.
[0085] While the foregoing describes various embodiments of the invention, other and
further embodiments of the invention may be devised without departing from the basic scope
thereof. The scope of the invention is determined by the claims that follow. The invention is not
limited to the described embodiments, versions or examples, which are included to enable a
