Along with the rapid development of information technology, in the town of central heating in the field of power station, flow rate, pressure and temperature measurement and control parameters such as high precision requirements are also according to the needs of the development of the cities in the heating load, heating allowed also increases the new pipelines and heating users. With the expanding of network, heat how to scientifically and effectively control and management of network, improve the network of economic benefits and social benefits, become heating enterprise urgent important topic. Using the embedded computer remote monitoring system can effectively solve the problem of the network control and management.Based on thermodynamic company central heating power station for research object, by heating engineering basic theory, combined with the current embedded computer application technology of central heating heating microcomputer monitoring system is analyzed and studied, according to the characteristics of central heating systems, using the embedded computer remote monitoring principle and design method based on embedded technology, computer monitoring system of heating. Examples are given to STM32 embedded chip as the main body of the hardware and software design of the modular design.Heating network operation control, uncertain,nonlinear and strong coupling, etc. Conventional PID control to meet heating water temperature control requirements. Therefore, this paper adopts the fuzzy PID algorithm for heat exchanger, the simulation model by using fuzzy inference control of PID parameters, and online. MATLAB software to control algorithm is studied and the simulation, the simulation results show that the controller is small overshoots and better stability.This paper mainly expounds the embedded system of heating data acquisition controller design of hardware and software design, and using the method of modular design, Discuss the guarantee system is stable and reliable operation, and the key technology of heat adjustment; Understand the GPRS networks communication principle, Studied how to realize and DTU - GPRS data communications between center. This subject has been successfully used for heating enterprise, for urban heating network monitoring operation opened a new research direction, this subject adopts control theory and method for urban water supply, gas pipeline and petroleum, chemical, intelligent network and other long-range industrial control field.
