Design And Application Of Heating Monitoring System Of Daqing Oilfield

The central heating system is a complicated large variable control system. With the improvement of people's demand of material life, this system will become more and more complicated. So it seems particularly important to regulate and control the hot network on the basis of accurate model building.In this way, study the simulation regulation method on computer of heating network and emulation system. The simulation regulation model of the waterpower stare and the identification model of the thermal condition for heating network were set up, get the equation for the change of temperature for the pipe that have heat source and cool source. Based on these models after summarizing domestic and international hot networks regulating experience, I raised the controlling policy based on the stepped models regulations. Both the primary regulation and the run regulating use the method of based model. And give the regulation method of the primary regulation and the run regulation in detail. Compare with regulation method on traditions, this method is more accurate, more convenient and more quickly.After doing a research about the hard wares and soft wares which are parts of computer monitoring system for heating networks, the hardware is used the SCADA distributed control system. The form of communication is used wire, and checking points distributing which will conduct the construction applying for heating network was given.
