基于ZigBee的污水监测系统节点软件设计

Sewage monitoring system node software design based on ZigBee

针对现有污水监测手段偏远、分散、缺乏稳定性等不足,将ZigBee技术应用于污水监测系统中,并提出一种基于ZigBee的传感器节点和无线网关节点的软件设计方案。主要利用ZigBee 2007协议栈的API函数完成下端ZigBee网络的组建和数据传输,并通过编写传感器节点数据采集程序完成pH值数据的采集,以及通过AT指令控制GPRS模块实现采集数据的远程传输。实验测试表明,节点能够顺利完成污水pH值的采集、传输和处理的目标,软件能够满足在实际应用中的要求,设计合理、运行稳定可靠。

For existing sewage monitoring method, remote, dispersed, lack of inadequate stability, the ZigBee technology in sewage monitoring system and software design solutions proposed wireless sensor node and a gateway node based on ZigBee. The main advantage of ZigBee 2007 stack API function to complete the formation of the lower end of the ZigBee network and data transmission, and complete the pH value of the data collected through the preparation of a sensor node data collection procedures, as well as through AT commands to control GPRS module for long-range transmission and data collection. Experimental tests have shown that the node can successfully complete the target of collecting sewage pH value, transmission and processing software to meet the requirements in practical applications, reasonable design, stable and reliable operation.
