基于MODEM网络的自动远程监控系统

Auto-remote Watching and Control System Based on MODEM Network

本文研发了一种利用公共市话网作为传输媒介的远程监控系统。系统采用PC机作为监控主机、PC机或者单片机作为采集单元、利用电话线作为二者数据交换与传输媒介、采用VB作为监控平台,来实现市区范围内几十个至上百个采集点的数据集中监控与应急处理。由于电话线网络通讯稳定、受干扰小、覆盖区域广且能实现无人化管理的特点,因此该系统有很大的应用前景。

An auto- remote watching and control system using public telephone net- work as transfer media is researched and designed in this paper. The system takes PC as monitor, takes PC or single chip microprocessor as sampling unit, uses telephone wire as transfer media of data exchange and takes VB as monitoring platform. This system aims at realizing center monitoring of data from tens or hundreds of sampling point and also aims at taking immediate agency. Because of its stable communication, low affection, wide...
