基于GPRS短消息的水质参数无线监测系统设计

Design of Wireless Monitoring System for Parameter of Water Quality Based on GPRS Short Message

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的通讯原理,以S3C2440微处理器为核心器件,利用传感器进行水质各参数的实时数据采集,测得数据以GPRS短消息的方式发送到手机或远程监控中心.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.

A designing scheme of remote monitoring system for parameters of water quality based on GPRS is put forward, which mainly tries to improve the existing problems in traditional method such as low monitor frequency, more errors in sampling, much dispersion in data. By studing the communication principle of GPRS carefully with the use of the S3 C2440 microprocessor as the core device and the sensor to sample data in real-time, the da- ta can be sent to cell phone or remote monitoring center in the form of GPRS short message. 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 T＆C system.
