Insert the second buckle 6.3 on the front cover 6 into the corresponding slot 2.2 of the panel body 2, and then move it downward so that the third limiting rib 7.2 of the rear cover 7 is engaged with the third buckle 2.3 of the panel body 2, and then use screws to fasten the limiting hole 7.3 of the rear cover with the limiting column hole 2.4 of the panel body 2 to complete the installation of the control panel assembly.

[0042] The gesture recognition sensor 4 includes a sensor 9 , a recognition module 10 and a control module 12 . The sensor 9 , the recognition module 10 and the control module 12 are electrically connected to each other.

[0043] The sensor 9 is the core part of the gesture recognition system, and is usually a photoelectric sensor, an inertial sensor, a depth sensor, etc. These sensors 9 can capture the user's hand movements and transmit the captured data to the recognition module 10;

[0044] Among them: Optical sensors are a common type of sensor, which can identify the user's intention by capturing the light from the user's hand and analyzing the light intensity, color and other information; Common optical sensors include infrared sensors, cameras, etc.

[0045] Inertial sensors capture the acceleration, angular velocity and other information of the user's hand, analyze the movement of the user's hand, and thus identify the user's intention. Common inertial sensors include gyroscopes, accelerometers, etc.

[0046] Depth sensors capture the depth information of the user's hand and analyze the position information of the user's hand to identify the user's intention. Common depth sensors include lidar, cameras, etc.

[0047] The recognition module 10 is a key part of the gesture recognition system, responsible for converting the data captured by the sensor 9 into digital signals, and then identifying the user's intention; common recognition modules 10 include single-chip microcomputers, embedded processors, etc.

[0048] The control module 12 is responsible for controlling the operation of the sensor 9, including initialization, data acquisition, data processing, etc. The control module 12 usually cooperates with the recognition module 10 to enable the gesture recognition system to work normally.

[0049] As a new type of sensor technology, gesture recognition sensor 4 has a very high application prospect. By exploring the principle of gesture recognition sensor 4, we can better understand the working principle of gesture recognition technology and provide theoretical support for the development of gesture recognition system. At the same time, with the continuous advancement of technology, gesture recognition sensor 4 will be further improved in terms of accuracy, speed, stability, etc., bringing more convenience to people's lives.
