The Design And Implementation Of Switch Based On Moving Target Charge Induction

As one of the three foundations of modern information technology,sensors are widely used in intelligent control systems,among which intelligent lamp control system and camera assistant system are its important application fields.In order to save energy,reduce pollution and improve the environment,the research of intelligent lamp control system is developing rapidly all over the world.With the development of economy and society,the camera assistant monitoring system in the field of security has developed rapidly to protect the life and property of the people.Because of the existing shortcomings of the intelligent lamp control system,such as insufficient sensing distance,high equipment cost,difficult maintenance and so on,as well as the shortcomings of the camera assistant monitoring system,such as insufficient inductive distance and large power consumption,and so on,a new intelligent lamp control system and camera assistant monitoring system are presented in the paper.The main contents of this paper are as follows,the principle of charge induction is studied,including the theoretical analysis,the establishment of the induction charge model on the metal surface and the derivation of the calculation formula.The charge sensing detection model of moving target is established,including the establishment of the model and the derivation of the relevant formulas and the correctness of the model is verified by the suitcase experiment.The detection of the motion human body charge sensing is realized,including the design of the circuit and the experimental results in different seasons.The intelligent lamp control system is realized,including the design of the circuits,the code design of MCU,the construction and performance test of the system and the comparison between the intelligent lamp control system and infrared intelligent lamp control system in terms of detection distance,detection angle and masking ability.The camera assistant monitoring system is realized,including circuit design,system construction and test.Based on the principle of charge induction,a new type of sensor is designed in this paper.Through the design of the circuit and the design of MCU,the performance of the intelligent lamp control system and the camera assistant monitoring system demonstrates that the proposed method can detect the moving target at any orientation whatever with or without occlusion and the detection distance can reach more than 3 m for the moving target.
