Design and application of infrared receiving system
Abstract:This paper mainly discusses the infrared receiving system used in daily life, the main purpose is to realize the remote control of a remote infrared operation, the application of the infrared technology widely and remote control together, mainly the use of HOT51 development board PC838 infrared receiving head based on STC90C51 chip, and 6122 the remote control to complete a transmitted signal, the received signal, and finally shows the process of the digital signal. Using 6122 remote controller emitting infrared signal, receiving head through the PC838 infrared receiving the optical signal and through the STC90C51 chip is to amplify the signal, decoding and so on a series of operations, the infrared signal into digital signal and send the digital imaging digital models to send into tube, to press one of the number keys on the remote controller, digital tube displays the corresponding digital effect.
This paper achieved the idea, design and implementation of the hardware circuit of the system, the design of system software and debugging are completed. The display function can realize.
