为满足对城市空气质量的实时监测,设计了基于GPRS通信的远程空气质量监测系统.系统终端节点利用电化学空气传感器和MSP430F149单片机分别完成对气体浓度的检测和数据处理,然后将数据经GPRS通信模块送至中心服务器.中心服务器建立了数据库存储数据,并配置了专用软件完成查询、统计和绘图等操作.系统采用模块化设计,使用方便灵活.%To realize the real-time monitoring of city air quality, a remote monitoring system has been designed based on GPRS communications. The terminal node of this system using electrochemical sensors and MSP430F149 microprocessor to realize detection of gas saturation and data processing. Then the processed data was sent to a server central by adopting GPRS wireless module and stored in a database and complete the query,statistics and mapping and other operations by a specially designed software. This system that constituted with independent modules can be used flexibly.
