Relay Device Design of Bridge Detecting System Based on Wireless Communication Network

针对现有桥梁应变多点检测中存在的问题引入无线通信、嵌入式、低功耗等技术,使用C8051微控制器和nRF905无线芯片实现无线组网中转,增加组网能力及测量距离。设计完善的特定无线网络通信协议和基于该协议之上的网络调试接口,使有限的信道得到最大利用,无线数据传输速率得到提高,并增强调试安装测试的灵活性、适应性。该系统不仅能完成传统的静态测试,而且能完成动态测试和单路实时显示。

The system solves many difficult problems in current bridge detecting systems by using wireless communication technology, embedded technology and low power design technology. This paper designs a relay device with C8051 micro-controller and nRF905 wireless chips to increase more terminal nodes and enlarge the scope. It designs a wireless net communication protocol and net debugging interface for the system to make full use of the communication channels, increase the speed of communication data and make it agile and easy to debug and equip. This system can also do static detection, dynamic detection and real time data display for one channel.
