区域远程排污实时监测网络系统

随着我国经济的快速发展，环境污染和保护越来越受到各界人士的关注。在区域内实施实时在线监测企业排污情况，是一种掌握排污实情，防止自报数据失真的有效方法。就区域范围内的远程排污监测系统进行了探讨，提出了一种切实可行的实时监测网络系统，由现场微机系统、主控计算机、软件系统及通讯层等组成，现场采用RS485／RS422工业通讯网络和智能仪表进行信号采集和汇总，远程采用现有通讯手段汇总至区域主控计算机，并对远程通讯的几种方法进行了对比和选择。该系统可用于远程排污实时监测亦可用于区域环境监测等领域。

Monitoring network system in remote unloading

With the rapid development of the economy, more and more attention is paid to the environment pollution and protection. To inspect on line the contamination blown off from companies is an effective way to master pollution facts and avoid distorted data. The system of monitoring unloading among long\|distance areas has been studied, and a scheme of real\|time monitoring is put forward which consists of microcomputers, a main computer, and software etc. The RS485 and RS422 of industrial communication network and intelligent meters are used in locale to transmit information to the main\|computer, and the Internet or telephone lines are used to transmit information for long distances. The comparison and selection of several communication methods are done at the same time. This monitoring network system can be applied to real\|time remote environmental unloading monitoring and to other areas.
