Design of wireless monitoring system for parameter of water quality based on GPRS

针对传统水质监测存在的监测频次低、采样误差大、监测数据分散等问题,提出基于GPRS的水质参数远程监测系统设计方案,研究了GPRS的通信原理,采用基于ARM的S3C2440A芯片为核心设计的硬件电路,利用传感器进行水质各参数的实时数据采集,通过公网无线数据通道为传输手段,构建了监控管理信息平台。测试表明,该系统可实现对水质参数的无线实时监测和数据分析,且对其他无线测控系统具有良好的可扩展性。

This paper puts forward a designing scheme of remote monitoring system for parameters of water quality based on GPRS, which is mainly try to improve the existing problems in traditional method such as low monitor frequency, more error in sampling, much dispersion in data. After carefully study the communication principle of GPRS, the monitoring information platform is constructed by adopting chip S3C2440A as key of hardware circuit, making use of sensor to sample data in real-time, and with public GPRS as data channel. The test turns out that the system works well in function of wireless data channel and data analysis, moreover, it has good property in expansibility for other wireless test ＆ control system.
