摘要
对集散二级集中供暖监控系统做了分析,第一级为微型机监控中心,负责选择全网的运行方式,通过ASDL MODEM方式读取各本地监控站数据,通过仿真系统对热网控制运行分析,使之达到最优化运行;第二级为本地监控站,负责测量各种所需的过程参数,通过GPRS网络无线向一级监控中心传输数据,并接收来自一级监控中心传来的控制参数,在监控中心的控制下运行。
The central heating supervisory control system is a two class distributed control system in this paper. The first is microcomputer supervisory control center. It takes charge of running way of the whole network. It get data from every field supervisory control station by ASDL MODEM and analyze the running way of the heating network by emulation system, to get optimal running status. The second is the field supervisory control station. It takes charge of measuring the process parameters. It transfers data to the supervisory control center by GPRS network and receive the control parameters, It runs under the control of supervisory control center.
