The mobile device of the embodiment does not need to be connected with the operated device in a bidirectional way, specifically, a specific operated mode is firstly given to each key on the operated device, the specific operated mode of each key is different, and then a corresponding optical signal is set for each specific operated mode. When the user controls the operated equipment, only a corresponding virtual key interface is generated on the operation interface of the mobile equipment of the user, the user presses the virtual key according to the requirement, the flash lamp of the mobile equipment sends out a light signal corresponding to the pressed virtual key, the light signal is received by the light sensing device of the operated equipment, the light sensing device transmits the received light signal to the controller of the operated equipment, then the controller of the operated equipment converts the received light signal into a specific operated mode corresponding to the key, and triggers an action command of the key, so that the operated equipment is controlled to generate corresponding action. That is to say, in this embodiment, the mobile device does not need to perform two-way communication with the operated device, but controls the operated device by generating an optical signal, and after the operated device receives the optical signal, the mobile device triggers an action command of the key, that is, in the prior art, the key of the operated device needs to be pressed to trigger the action command of the key, but in this embodiment, the action command of the key is triggered by the optical signal without touching the key of the operated device, so as to control the operated device to perform a corresponding action. The invention transmits the control signal through the optical signal without two-way communication, reduces the occurrence of the conditions of signal delay or error and the like, has simple and convenient control mode, low error rate of optical signal transmission and high real-time property, and can more accurately control the corresponding operated equipment. Preferably, the light sensing device of the present embodiment is a prior art. In addition, after receiving the optical signal, the operated device can convert the optical signal into an operable signal such as an electrical signal, a mechanical signal, etc., as long as the optical signal can be converted into a specific operated mode, which is not limited in this embodiment.
In the method for operating keys without contact provided by this embodiment, as shown in fig. 1, further, in step a of this embodiment, the specific operated mode assigned to each key is different operation digit codes; in step c, the mobile device generates an optical signal corresponding to the operation digit code of each key; in step d, after the light sensing device receives the light signal of the mobile device, the operated device converts the light signal into an operation digital code of a key of the operated device, and triggers an action command of the corresponding key, so that the operated device completes a corresponding action result.
Specifically, the operation digit codes can be set by the system, the operation digit codes corresponding to each key are different, that is, each key has its own code, such as a code with specificity, such as a digital code, an english code, and the like, different optical signals are designed for each different operation digit code, after the mobile device presses the virtual key, the flash lamp of the mobile device sends out an optical signal corresponding to the pressed virtual key, so that after the optical sensing device receives the optical signal, the controller of the operated device can convert the optical signal into the corresponding operation digit code, an action command of the corresponding key of the operated device is triggered, the operated device is controlled to act, and the purpose of contactless control is achieved. The embodiment realizes the non-contact control key by the cooperation of the optical signal and the operation digit code, avoids the control mode of two-way communication, contributes to improving the accuracy and the real-time performance of control, prevents the occurrence of the conditions of signal delay, incapability of connection or trouble connection which often occur in the two-way communication, and makes the embodiment have higher practicability.
As shown in fig. 1, as an implementation manner of this embodiment, in step b, a two-dimensional code is set, where the two-dimensional code can be set at any place that can be observed and scanned by a user, and the mobile device obtains key setting information corresponding to the operated device by scanning the two-dimensional code.
Specifically, in the existing bidirectional communication connection, taking bluetooth wireless connection as an example, a user needs to open bluetooth first and then searches for a bluetooth signal of a device to be connected, and then performs bidirectional connection, and the time waiting for connection often occurs in the middle, which is very troublesome, and since more than one user may be used at the same time, a conflict is likely to occur, in addition, the user connects a personal mobile device with a public device through a network or bluetooth, and information safety hazards such as information leakage also exist, which is not convenient for the user to use. The mobile device is capable of generating a specific optical signal, and the two-dimensional code is arranged on a display screen or a device housing of the operated device, so that the user can see the specific optical signal conveniently. For example, when the operated device is an elevator, a two-dimensional code and a light sensing device are arranged at a prominent part in the elevator, when a user takes the elevator, the two-dimensional code is firstly scanned to obtain floor key information of the elevator, a corresponding virtual key operation interface is formed on a mobile phone, when the user wants to ascend to a 9 th floor, the virtual key 9 is pressed on the mobile phone, a flash lamp of the mobile phone sends out an optical signal corresponding to the 9, the light sensing device of the elevator receives the optical signal, the optical signal is converted into a control command of the corresponding key 9 by a controller of the elevator, and the elevator is triggered to directly ascend to the 9 th floor, so that the user can control the ascending and descending of the elevator without touch, the process has no complicated two-way communication connection, and only needs to operate through mobile devices such as the mobile phone. That is to say, this embodiment uses through the cooperation of two-dimensional code, light signal and light sense device, makes the user need not to adopt bluetooth or network to equal to be connected by operating means, does not have the network delay, signal delay to lead to etc. and is difficult to connect the scheduling problem, does not have the problem of information potential safety hazard yet, and the user only needs to scan the two-dimensional code, and then realizes transmission control alright through light signal.

As another implementation manner of this embodiment, the two-dimensional code may be set on paper, and then pasted to other positions, such as a wall surface, other facilities, and the like, that can be scanned by the mobile device on the operated device, so that the user can scan the two-dimensional code conveniently; of course, the two-dimensional code may also be disposed on something other than paper, such as a photo, and the like, and this embodiment is not limited.
In the method for operating a key without contact provided by this embodiment, in step c, after different virtual keys on a virtual key interface of the mobile device are pressed, each optical signal generated by the mobile device corresponding to the different keys is a signal with different light intensity and different time length.
Specifically, as shown in fig. 1, the light signals may be arranged in various ways, for example, each light signal is distinguished by a continuous light duration, when the key a is pressed, a flash of the mobile device emits light for 0.2 seconds, when the key B is pressed, the flash of the mobile device emits light for 0.4 seconds, and the like, so that when the light sensing device senses different light durations, the light sensing device can convert the light durations into operation digit codes of different keys, and then the keys are controlled to sense. As another embodiment, each optical signal may include a plurality of short signals with different light durations, as shown in fig. 1, taking 5 short signals as an example, when the key a is pressed, the optical signal sent by the mobile device is: bright, go, bright, go and bright; when the key B is pressed, the optical signal sent by the mobile device is: go out, light, go out; by analogy, the on-off of 5 short signals are arranged, so that a plurality of different on-off combinations can be provided, and different keys can be corresponding to the short signals. And the number of short signals is set according to the number of actual keys. Furthermore, the lighting time of the plurality of short signals can be set, for example, the short signals are all arranged in a "lighting-on-off lighting-off" mode, wherein the lighting time of the key a is 0.2 second, and the lighting time of the key B is 0.4 second, so that two groups of different light signals are formed, and the light sensing device can sense and convert the light signals into the operation digit codes of the corresponding keys. Therefore, the optical signal of the present embodiment can have various different setting modes, and the setting can be performed according to actual requirements. Due to the arrangement modes of various optical signals, the method for operating the keys in a non-contact manner is more suitable for public equipment with a plurality of keys or needing to be pressed, and the situations of signal errors, delay and the like are not easy to occur.
In addition, the method for operating the key without contact in the embodiment is applicable to various public devices, such as elevators, vending machines, and the like, which need to be operated by the key, and is not limited herein.
