Human body intelligent identification and gesture operation control system

Abstract

The invention discloses a human body intelligent identification and gesture operation control system. The system comprises a microcontroller, an operator connected with the microcontroller, and a human body induction identification apparatus and an action identification apparatus mounted on the operator, wherein the human body induction identification apparatus is a pyroelectric infrared sensor; the microcontroller judges entering and leaving of a human body according to a signal fed back by the pyroelectric infrared sensor; action identification sensors are at least two groups of infrared transceiver sensors; and the microcontroller judges whether the direction of a gesture action is leftward or rightward according to a time difference of signal changes of different groups of the infrared transceiver sensors, thereby changing a working state of a controlled electric appliance. According to the system, the pyroelectric infrared sensor is used for judging entering and leaving of the human body; the at least two groups of the infrared transceiver sensors are used for judging the gesture action of the human body; and the working state of the controlled electric appliance is changed according to the gesture action, so that the operation process is simplified, intelligent automatic startup and shutdown of the controlled electric appliance are realized, the control is convenient and intelligent, and the identification accuracy is high.

Description

technical field [0001] The invention relates to the technical field of intelligent control of household appliances, in particular to a human body intelligent recognition and gesture operation control system. Background technique [0002] At present, the wake-up and operation of the interactive panels of household appliances (such as gas water heaters and range hoods) on the market mainly use buttons and touches. Its application mainly has the following deficiencies: [0003] 1) The panel without switch button light is not easy to find the corresponding button to operate when the light is dark, which increases the difficulty of operation. For gas water heaters with on / off button power indicator function, the power LED light is always on, the LED indicator light works for a long time, the brightness and life are gradually reduced, and it is easy to be damaged [0004] 2) Many household appliances need to touch different buttons when they are turned on and used, which is cumb...

AI Technical Summary

Problems solved by technology

[0003] 1) The panel without switch button light is not easy to find the corresponding button to operate when the light is dark, which increases the difficulty of operation

For gas water heaters with on / off button power indicator function, the power LED light is always on, and the LED indicator light works for a long time, and the brightness and life are gradually reduced, which is very easy to damage

[0004] 2) Many household appliances need to touch different buttons when they are turned on, which is cumbersome to control

[0005] 3) The response of the buttons is not easy to control. Due to the influence of structural size changes, failures such as stuck or virtual keys are prone to occur, and the life of the buttons is limited, and the operating experience is poor

[0006] 4) Although the touch buttons are relatively mature and easy to use, they still need to be operated by touch, and the convenience is not high

Especially for the range hood, after long-term use of the hood, the surface of the panel is covered with oil stains, and the sensitivity of the touch operation is low
