Abstract: The paper designs a kind of wireless communication system applied in strong interference environment of mine,analyzes the influence of the best wireless communication principle and interference on system,using the methods of channel identification,setting signal delay identification code,tag code, radix-minus-one complement comparison,error retransmission method, the paper designs communication protocol software.The design of physical layer hardware interface definition can be flexible to change.Using A/D interface and communication interface weighted circuit of the host,the design of software communication protocol layer uses interrupt and count delay to solve matching problem.The design of application layer can be integrated into I2C network application products for the users.
