“无人值守”热力站计算机监控系统

Computerized Supervisory System of "Unmanned On Duty" Heating Power Station

在对典型的集中供热系统进行描述的基础上 ,具体介绍了监控系统的构成 ,软、硬件及通信的设计。方案采用上、下位机结构组成计算机监控系统自动监控供热系统的运行状况 ,下位机测量和调节热力站的运行参数 ,并通过Modem和电话网向上位机传送数据和报警信号 ;上位机管理和分析数据 。

On the basis of describing typical centralized heat supply system the composition of supervisory system, hardware and software as well as design of communication are introduced concretely. The strategy adopts structure of host computer and slave computer, the computerized supervisory system automatically monitoring the operation status of heat supply system. Measurement and regulation of the operational parameters are implemented by the slave computer; data and alarm signals are sent to host computer modem to telephone network; data are managed and analyzed and control commands are issued by host computer.
