Wireless signal arbitration system based on microcontroller

Signal arbitration requests system to determine multi-signal´s priority based on their input time. Controlled by microcontroller, the wireless signal arbitration system is composed of encoder and decoder chip, wireless transmitter and wireless receiver circuits. Compared with the traditional all-hardware circuits (priority encoder, decoder and the trigger) that constitute the control system, wireless technology makes this system stable and convenient. The thoughts of the whole system design are given. The structure and design of transmission unit are described. The usage and problems of the encoder and the radio frequency transmitter module that should be paid attention to when using are introduced. Receiving cell which is composed of decoder and the radio frequency receiver module is presented. The single chip processing unit is referred to and the program flow chart of the microcontroller, as well as the control procedure is given. Experiments show that the system is easy to be realized and is flexible to be expanded according to actual needs.
