摘要
针对实现无人值守条件下污染源排放的远程监测,提出了基于GPRS网络的环境参数监测系统设计方案,设计并实现了LPC2200微控制器和GPRS通信模块为核心的数据采集传输仪,包括基于MAX1270的模/数转换电路、SD2405AP的时钟电路、SST39VF1601的数据存储电路等。根据通信的需要,设计并实现了传输仪与监测站之间的通信协议。经过实测,传输仪能够将现场采集到的监测数据准确、可靠地传输到监测站,并有效解决了监测点遗漏问题。
In order to achieve remote monitoring of pollution sources in the unattended condition,a scheme of monitoring system based on GPRS network was proposed.Data acquisition and transmission device was designed and implemented with the LPC2200 microcontroller and GPRS communication module as the core,including analog-digital conversion circuit based on the MAX1270 chip,clock circuit with SD2405AP chip and data storage circuit with the SST39VF1601 chip.According to communication needs,communication protocol between data transmission device and monitoring station was designed and implemented.Through practical application,it shows that the transmission device can able to transmit field data to monitoring station accurately and reliably and the problem of missing monitoring points was solved effectively.
