摘要
同其他发达国家相比我国的环境质量监测起步较晚,但近几年环保力度逐渐加大。作为环境质量监测的重要组成部分,空气质量监测也越来越受到人们的重视。
     AQMS(空气质量监测系统)是一个对空气质量进行连续监测的自动化系统。在对AQMS功能和特点分析的基础上,本文提出了三级结构模型的AQMS。第一级为调度级,中心站服务器负责汇总和处理所有数据,控制所有站级工控机和现地级仪器;第二级站级工控机,通过公共电信网与中心站进行通信,响应中心站服务器,从各仪器采集数据、控制本站仪器。现地级监测仪器处于三级系统的最底层,完成对空气中各种污染物的数据采集。我们在通信双方各接入一个调制解调器(MODEM)并借助公共电信网络来实现计算机之间的远程通信。文章着重说明了在AQMS中子站系统中数据采集和数据处理的过程和方法,克服了数据采集中响应缓慢的问题,实现了在数据处理中的报警功能,强化了报告输出的功能,改善了图表的实时显示功能。
The monitoring of the environment started recently but develops rapidly in our country. As an important component of environment monitoring, air quality monitoring has been paid more attentions on now.
    AQMS (Air Quality Monitoring System) can monitor air quality automatically and continuously. It includes three levels in function. In first level, the central server can collects data from substation and control all the relevant computers and instruments. The substation computers is the second level, they can communicate with central server through PSTN ( Public Switched Telephone Network), they also collect data from instruments of its own and control them. The last level is composed of monitoring instruments that collect data from outer air. It is the base of the whole system. We set a Modem via RS-232 interface on two computers to realize the telecommunication. This article emphasizes on the processes and methods of collecting and processing data, resolves the questions of response and data alarm, and strengthens the functions of reports and diagrams.
