Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a flowchart illustrating a first step of a first embodiment of a key triggering method of the present invention is shown, which may specifically include the following steps:

step 101, emitting a plurality of laser beams, wherein the laser beams form a laser plane;

in the embodiment of the present invention, a laser emitter may be used to emit laser beams, and the laser beams are parallel to each other to form a laser plane. The laser plane is covered on the plane of the original entity key in parallel.

It should be noted that, the distance between the laser plane and the physical key is not too small, so as to prevent the user from touching the physical key by mistake when no touch operation is performed, and the distance between the laser plane and the physical key is also not too large, so that the user can observe the position of the physical key conveniently.

In addition, the number of the laser emitters is as large as possible, so that the laser beams are dense enough to form a more tight laser plane, and the situation that the laser beams cannot be irradiated when the fingers of the user pass through the laser plane is prevented.

Step 102, monitoring the laser plane, and acquiring a click coordinate of a reflection light spot when the reflection light spot appears on the laser plane;

and after the construction of a laser plane is completed by a plurality of emitted laser beams, the laser plane is monitored in real time to obtain a real-time monitoring image. Specifically, the monitoring function may be realized by providing a monitoring camera having a laser receiving device, such as a CCD camera or a CMOS camera. Among them, a CCD (Charge coupled Device) is a semiconductor Device that can convert an optical image into a digital signal. The tiny photosensitive substances implanted on the CCD are called pixels. The larger the number of pixels contained in a CCD, the higher the resolution of the picture it provides. The function of a CCD is to convert the image pixels into digital signals. The CCD has many capacitors arranged in order to sense light and convert the image into digital signal. It should be noted that a plurality of cameras can be arranged at different angles to prevent the finger from being blocked by a body or other objects and thus the reflected light spot cannot be detected.

When a user needs to trigger a certain entity key by a finger in a non-contact manner, the finger penetrates through the laser plane above the entity key without actually contacting the entity key, a laser beam irradiates the finger to be reflected, a reflection light spot is formed on the laser plane, when the reflection light spot is detected in a real-time monitoring image, the click coordinate of the reflection light spot is obtained, and the click coordinate of the reflection light spot is a plane two-dimensional coordinate.

Specifically, a two-dimensional coordinate system may be established in the monitoring image, and then the coordinates of the reflection light spot in the two-dimensional coordinate system are calculated to obtain the click coordinates.

103, determining key information by adopting the click coordinates;

after the click coordinate is obtained through calculation, the click coordinate can be adopted to determine the key information of the entity key clicked by the user in a non-contact manner. The key information has a coordinate identification range of the key, and a corresponding relation between the key number and the key.

In the embodiment of the invention, each key has a coordinate identification range, when the click coordinate of the non-contact click is located in the coordinate identification range, the click is determined to be an effective click, and when the click coordinate of the non-contact click is located outside the coordinate identification range, the click is determined to be an invalid click, so that the user can be reminded to click again.

The coordinate identification range can be a circular identification range taking the center of the entity key as the circle center, and the radius of the circular identification range can be adaptively adjusted according to the actual distance between each key and the key. It should be noted that if the coordinate recognition range set by each key is too small, the success rate of effective clicking is reduced, and if the coordinate recognition range set by each key is too large, the coordinate recognition ranges between the keys may overlap, resulting in a situation where one click occurs and multiple keys are triggered.

In addition, each key also has its own key number, for example, the key number corresponding to the elevator first-floor key may be 01, and the key number corresponding to the elevator second-floor key may be 02.

Specifically, the step of determining the key information by using the click coordinate includes:

a substep 1031, judging whether the click coordinate is located in the coordinate identification range;

sub-step 1032, if yes, determining the key number corresponding to the coordinate identification range;

and a substep 1033, if not, generating a re-click reminding message.

For example, the key number 03 corresponds to a coordinate identification range having an abscissa of 2, an ordinate of 3 as a center, and a radius of 1, and when a click coordinate having an abscissa of 2.5 and an ordinate of 3.5 is detected, it is determined that the click coordinate is located within the coordinate identification range, and then the corresponding key number 03 is determined.

And 104, triggering the key corresponding to the key information.

When the clicking operation of the user is effective clicking and the key number is determined, the key corresponding to the key number can be triggered.

In an optional embodiment of the present invention, the key is connected to a corresponding switch circuit, and the step of triggering the key corresponding to the key information includes:

generating a protocol signal by adopting the key number; the protocol signals are used for indicating the on and off of a switch circuit connected with the keys, and the protocol signals corresponding to the keys are different.

Specifically, the protocol signal may be converted into an analog signal to indicate the conduction of a switch circuit connected to the key, so as to trigger the key.

In the embodiment of the invention, a plurality of laser beams are emitted, the laser beams form a laser plane, the laser plane is monitored, when a reflection light spot appears on the laser plane, a click coordinate of the reflection light spot is obtained, the click coordinate is adopted to determine key information, and a key corresponding to the key information is triggered, so that the non-contact triggering of the key is realized, the persistence and the propagation of bacteria and viruses are avoided, meanwhile, the solid key does not need to be replaced, the installation efficiency is improved, and the hardware cost is greatly reduced.
