The Design Of The Heating Network Long-distanc Monitoring System And The Application Of Anneng Urban Heating Network

Central heating long-distance monitoring system of Hefei Thermo Electron Corporation is regarded as the study object in this article. The design background and thoughts, the system constitution are introduced and the realization of long-distance communication and the database constitution are analyzed.The article introduces the industrial control system is developed from DCS to FCS gradually. DCS and FCS are integrated with each other in structure. When the technique of Ethernet and Internet is applied in the industrial control area, the distributed control system will have wider opening and development space.1.The article analyzes the structure and design thoughts of SCADA and discusses the technique about the realization long-distance monitoring system, especially about GPRS.2.The distributed control system is applied in the monitoring system. Intelligent instrument is formed the control station of the base system and IPC is formed the monitoring operator station so that the functions such as data acquisition, control, display will be implemented. On that basis, long-distance monitoring system based on Web will be established through Internet and Intranet.3.Considering the need of industrial field, the writer designs configuration software, builds the frame of the software, completes the function design of the module such as graphics interfaces, real time database system, trend chart, report forms and so on.The whole system has good flexibility, brief MMI and applicability. It is worth popularizing.
