Description:BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to a locking system and particularly to a locking system and a method for contactless locking using a photo coding technique.
Description of Related Art
[002] Security is a crucial aspect of our daily lives, whether it's at home, work, or out in public. It ensures safety and peace and is necessary for the smooth functioning of any business or domestic scenario. Security can be broadly categorized into physical security and asset security. Physical security refers to protecting physical spaces or objects from unauthorized access, while asset security involves safeguarding valuable assets like ideas and creations from being reused or stolen. One common way to ensure physical security is through locking systems, which come in various types, including mechanical, electronic, and biometric locks. However, each type has its own set of advantages and disadvantages. For example, mechanical locks are prone to failure, while electronic and biometric locks require an uninterrupted power supply to function.
[003] Despite the availability of these different types of locking systems, there are still several challenges associated with conventional locking systems. Keys can be lost, stolen, or duplicated, making it easy for unauthorized access. Electronic locking systems can also be vulnerable to hacking, while biometric locks may have issues with accuracy or reliability.
[004] Furthermore, the use of conventional locking systems often requires physical touch to operate, which can lead to the spread of microorganisms and communicable diseases. This is especially concerning when lockers are installed in public locations like gyms or banks.
[005] There is thus a need for an improved and advanced locking system for contactless locking that can administer the aforementioned limitations in a more efficient manner.

[0049] FIG. 1B illustrates a schematic circuit diagram of the locking system for contactless locking using the photo coding technique at a first instance of time, according to an embodiment of the present invention. In an embodiment of the present invention, the first instance of time, the locking system 100 may generate a first instance of the binary code (a first instance of the three-dimensional code).
[0050] In an exemplary embodiment of the present invention, the user may operate the locking system 100 by emitting light onto a first photodiode 110a. The position of light on the first photodiode 110a, the intensity of the light on the first photodiode 110a, and the time delay for changing the position of the light may be fed to the comparator 114, in an embodiment of the present invention. In an embodiment of the present invention, the comparator 114 may convert the light parameters into a first voltage.
[0051] In an embodiment of the present invention, the first voltage may further be fed to the A/D converter 116. The A/D converter 116 may convert the fed first voltage into the first instance of the binary code (the first instance of the three-dimensional code), in an embodiment of the present invention. In an embodiment of the present invention, the controller 118 may compare the three-dimensional code with the set code. Upon comparison, if the three-dimensional code matches with the set code, then the controller 118 may actuate the relay unit 124 to perform the unlocking mechanism, in an embodiment of the present invention.
[0052] In another embodiment of the present invention, the array of the photodiodes 110 may be utilized in the locking system 100. The locking system 100 may utilize 2 bits of value.

[0053] However, upon setup of the locking system 100 the user may be required to set a corresponding three-dimensional code. The corresponding three-dimensional code may be set by the user by programming corresponding light parameters into the locking system 100. The corresponding light parameters may be unique for every corresponding user.

[0054] FIG. 1C illustrates the schematic circuit diagram of the locking system for contactless locking using the photo coding technique at a second instance of time, according to an embodiment of the present invention. In an embodiment of the present invention, the second instance of the circuit of the locking system 100 may generate a second instance of the binary code (a second instance of the three-dimensional code).

The position of light on the nth photodiode 110n, the intensity of the light on the nth photodiodes 110n, and the time delay for changing the position of the light may be fed to the comparator 114, in an embodiment of the present invention. In an embodiment of the present invention, the comparator 114 may convert the light parameters into a second voltage.
[0056] In an embodiment of the present invention, the second voltage may further be fed to the A/D converter 116.

[0057] Referring to the FIG. 1B, and the FIG. 1C, the controller 118 may further compute the array, in an embodiment of the present invention. The array may be computed based upon the first instance of the three-dimensional code and the second instance of the three-dimensional code, in an embodiment of the present invention. Upon comparison, if the first instance of the three-dimensional code and the second instance of the three-dimensional code in the computed array match with the set code, then the controller 118 may actuate the relay unit 124 to perform the unlocking mechanism, in an embodiment of the present invention. The photo coding technique as disclosed in the present invention may ensures that each of the generated three-dimentional code is unique and difficult to duplicate, as the specific combination of light parameters required to generate the code would be difficult to replicate.

The controller 118 may comprise the programming instructions in the form of programming modules such as a data receiving module 200, a data comparison module 202, a signal generation module 204, and a relay actuation module 206.

Upon receipt of the three-dimensional code, the data comparison module 202 may be configured to compare the three-dimensional code with the set code stored in the memory 122 using the digital comparator 120, in an embodiment of the present invention.
[0061] In another embodiment of the present invention, the three-dimensional code may be in a form of an array. The three-dimensional code may be in the form of the array when the user may select various parameters for generation of the three-dimensional code, in an embodiment of the present invention.
[0062] In an exemplary scenario, if the user may have generated the three-dimensional code by selecting two positions (a first position and a second position) of light on the locking panel 108. The first position may be a top right position on the array of the photodiodes 110. The second position may be a bottom right position on the array of the photodiodes 110. Further, the user may expose the first position with the light for a first amount of time (for example 2 seconds), and the second position with the light for a second amount of time (for example 3 seconds).
[0063] Then the three-dimensional code may be in the form of the array, with entries in the array in a sequence of, firstly, the second position on the array of the photodiodes 110, and the second amount of time, and secondly, the first position on the array of the photodiodes 110, and the first amount of time.
[0064] Upon comparison, if the three-dimensional code and/or the array of the three-dimensional code matches with the set code, then the data comparison module 202 may transmit an actuation signal to the signal generation module 204. Else, the data comparison module 202 may be configured to activate the data receiving module 200 to continue receiving the generated three-dimensional code from the locking panel 108.
[0065] In an embodiment of the present invention, the signal generation module 204 may be configured to be activated upon receipt of the actuation signal from the data comparison module 202.

[0066] In an embodiment of the present invention, the relay actuation module 206 may be configured to be activated upon receipt of the actuation signal from the signal generation module 204. The relay actuation module 206 may be configured to actuate the relay unit 124 to perform the unlocking mechanism by transmitting the actuation signal to the relay unit 124, in an embodiment of the present invention.
[0067] FIG. 3 depicts a flowchart of a method 300 for generation of the three-dimensional code for the locking system 100, according to an embodiment of the present invention.
[0068] At step 302, the locking system 100 may enable the user to emit light from the LED torch 106.
[0069] At step 304, the locking system 100 may convert the light parameters of the detected light into the voltage.
[0070] At step 306, the locking system 100 may convert the voltage into the binary code.
[0071] At step 308, the locking system 100 may generate the three-dimensional code.
[0072] FIG. 4 depicts a flowchart of a method 400 of contactless locking using the photo coding technique by using the locking system 100, according to an embodiment of the present invention.
[0073] At step 402, the locking system 100 may generate the three-dimensional code using the locking panel 108 upon detecting the light by the photodiodes 110 of the locking panel 108.
[0074] At step 404, the locking system 100 may receive the generated three-dimensional code from the locking panel 108.
[0075] At step 406, the locking system 100 may compare the generated three-dimensional code with the set code stored in the memory 122 using the digital comparator 120. Upon comparison, if the generated three-dimensional code matches with the set code, then the method 400 may proceed to a step 408. Else, the method 300 may reverse back to the step 404.
[0076] At step 408, the locking system 100 may generate the actuation signal.
[0077] At step 410, the locking system 100 may actuate the relay unit 124 to perform the unlocking mechanism by transmitting the actuation signal to the relay unit 124.
