Abstract


The detecting system of infrared remote control is mainly used to test the function of controller and the corresponding between the controller and Set-top box. It can check whether the controller can output normal code to control its corresponding equipment.This paper describes the design process of a detecting system of infrared remote control which has better capability such as universal,compatible and good man-machine conversation interface. First of all, the hardware circuit and software of Micro Control Unit (MCU) to realize incepting of infrared code according to various data are designed. And the infrared code to the host computer via USB serial port is transmitted. Next,host computer decode the received infrared code using some related algorithm. Finally it realizes the detection through comparing the received infrared remote controller button codes with the existing correct code using good man—machine conversation interface. Besides, it can realize the corresponding between the controller and Set-top box through simulating infrared remote signal. Specifically, the design of the whole system was finished based on the analysis of coding method,the structure of code type,single-chip applications and single-chip serial data communications.Experiments show the system works well. It can realize the decoding and detection in parts of Infrared remote Controller. Thus it provides a new kind of detect system of infrared remote controller in product lines.
