基于GPRS的空气质量综合监测系统

为了提高空气质量综合监测水平，设计了一套基于GPRS的无线综合监测系统。该系统以AT89C51单片机为核心，主要包括大气参数监测模块、GPRS无线传输模块、A/D转换模块和LCD显示模块等。大气参数监测模块通过终端节点对大气参数进行实时采集，并将数据通过GPRS传输模块发送给主控端，实现对测量参数的实时显示、报警等功能。该系统为空气质量监测、空气污染预报等提供依据，具有重要的现实意义。

Comprehensive Monitoring System of Air Quality Based on GPRS

In order to improve the monitoring level of air quality,the wireless monitoring system based on the GPRS was designed. The system used AT89C51 microcontroller as the core,mainly including air parameters monitoring module,GPRS wireless transmission module,A/D conversion module,and LCD display module. The air parameters monitoring module collected the real-time date of air quality through the terminal node,and then sent the date through the GPRS transmission module to the main control end. At the same time,the system could implement the functions like real-time display and alarm lights of the measurement parameters. The sys-tem provided the reference for air quality monitoring and air pollution forecasting,which had important practical significance.
