设计一个应用于矿井强干扰环境的无线通信系统。分析了最佳无线通信原理及干扰对系统的影响;采用通道识别,设置信号延时识别码、标记码,反码比较,错误重发的方法,设计了通信协议软件;物理层硬件接口定义设计可以灵活改变,使用主机的A/D接口和通信接口加权电路,软件通信协议层的设计以中断和计数延时相结合解决匹配问题,应用层的设计可为用户集成到I2C网络应用产品中。
Design a wireless communication system which is used in mine environment with strong interference. The principle of wireless communication and the influence of interference on the system are analyzed. The communication protocol software is designed by using channel identification, signal delay identification code, marking code, anti-code comparison and error retransmission. The physical layer hardware interface definition design Can be flexibly changed, using the host’s A / D interface and communication interface weighting circuit, the design of the software communication protocol layer to solve the matching problem by the combination of interrupt and count delay, the application layer design can be integrated into the I2C network application products for users.
