Abstract:This paper takes 315MHz transmitting and receiving module as the core,combines with PT2262/PT2272 encoding and decoding chip,mechanical driving part,etc.,to form a complete wireless control system. Using the radio control principle,the remote control terminal transmits signals,which can make the receiving terminal receive and correctly drive the circuit action of the mechanical part,so as to realize the forward,backward,left and right turning work of the remote control toy car. This paper introduces in detail the modules of wireless control system of remote control vehicle,basic application,invention and development of radio,wireless remote control technology,basic knowledge and system type of wireless communication system,various chips and components used in the design:315MHz transmitting and receiving module’s technical specifications,working principle and cooperation mode. Based on wireless communication and radio remote control,this paper focuses on the practical application of wireless communication in life to design remote control toy car.
Keywords:315MHz wireless transmission and reception;PT2262/PT2272;wireless communication system;wireless remote control
