摘要
依据隧道环境监测需求及特点,提出了一种环境参数无线监测系统设计方案,实现了ZigBee短距离无线通信技术与GPRS远程通信技术的有效结合,完成了传感器网络中数据采集节点以及网络协调节点的硬件和软件开发,并设计了适合于数据实时传输的通信协议.测试表明,该系统测量误差小,可靠性高,适合应用于铁路隧道环境监测.
According to the demand and characteristics of tunnel environmental monitoring,a de-sign scheme of remote wireless monitoring system has been put forward to monitor tunnel envi-ronment parameters,which realizes the combination of ZigBee short distance wireless communica-tion technology and GPRS,completes the hardware and software design of sensor network data collection node and network coordinator node,and designs the communication protocol suitable for the real-time data transmission based on the platform.The test shows that the system has small measurement error and high reliability,and it is suitable for the environmental monitoring of rail-way tunnel.
