摘要
针对目前采用电话拨号方式进行数据通信的空气质量自动监测系统所存在的实时性差等问题,通过分析比较目前环境监控系统常用的几种通信方式的优缺点,提出了一种基于GPRS技术的空气质量监测数据通信系统,此系统主要由监测子站、传输网络和监控中心等部分组成,采用GPRS无线网络和Internet网络为通道来实现监测数据的远程传输和状态监控,以达到实时监控的目的。采用GPRS进行数据通信具有经济适用、永远在线、实时性好等优点。
At present, there are many problems such as poor real - time in ambient air quality monitoring system which attains data transfer using dial - up. In this case, this paper analyzed and compared several communication manners in environmental monitoring systems. And it proposed an air quality monitoring data communication system based on GPRS technology. The system mainly consisted of three parts ： the monitoring sub - stations, data transmission networks and control center, and it achieved the connection of GPRS network and Intemet to realize data transmission and status monitoring. It can attain real - time monitoring. Using GPRS for data communication manner has virtues of economy, online forever and real - time.
