一种集中监控系统的设计

Design of a center supervisory control system

主要介绍了机房集中监控系统的功能和组成。该监控系统主要完成对门禁系统、空调系统、UPS系统、配电柜系统和漏水报警系统的实时监测与控制,可动态显示每台设各的运行状况,对异常情况具有语音报警功能,可记录所有设备的实时信息。该系统使用 Visual++语言开发,采用多线程、多任务的方式对每个串口都能实现有效地监控,实现了微机对信号的采集、处理、历史数据的存储和查询。对系统的相关硬件、协议、通讯控制和软件设计进行了介绍。

This paper presents the composition and function of a center supervisory control system for computers house. Five kinds of monitored objects are PG2750(Gate Controller). Direct Expansion Room Units (center air- condition),Power Supplies(UPS), Power Measurement Meter and monitor of water leakage, the host computer can not only collect and save all objects real-time data, but also control parts of them. The alarm box will display on the computer screen when an object works wrongly and all alarm information would be saved. The supervisory con- trol system is developed with Visual C + + by using multithread and multitasks. It can finish remote date acquuisi- tion and process monitoring. The correlative hardware, protoocl, communication control and software are described in detail.
