The Research Of Urban Heating Network Centralized Detecting System

With the rapid development of science and information technology, the growing demand for heating, the traditional low level of automation of the heating pipe network adjustment control operation mode has been unable to meet the needs of the system now. At the same time, the heating system lack of centralized testing and optimization of control, making the network failure rate is higher, low operation efficiency. In order to further improve urban heating quality, improving the efficiency of the heating system, The research of urban heating network centralized detecting System has become the inevitable development trend.The urban district heating system as the research object in the paper, firstly, based on the ACX32 Controller, the completion of the frequency control of field devices and the design of the various parameters collection, designed the automatic monitoring of energy-saving control cabinet for the heating station. On this basis, researched the data collection and inspection and monitoring system, used the GPRS wireless telecommunications technology for data transmission, achieved the centralized detection control of heating network.Secondly, researched the optimal control of heating network, Design of fuzzy adaptive PID controller, to optimize control the secondary network side water temperature of the heat transfer stations, enhance the quality of heating network. Then, for optimal regulation of urban heating network control strategies were studied, proposed the optimization regulation control strategy.To sum up, researched the urban heating network centralized testing systems and optimal control in the paper, constituting an integral function of each subsystem, achieved the heating pipe network to achieve centralized testing, by integrating and sharing information, providing a favorable platform for managers, making the heating network to reach a state of dynamic equilibrium, to create a comfortable living environment for people.
