Ensure that these facilities operate safely on the national economy is of great significance. As peoples lives, public buildings, office and entertainment venues, is no exception. In this paper, Songyuan City, Jilin Province in the design of four unattended heat transfer stations, a savings of manpower, but also improve the management of high energy consumption and backward. In this paper, heat transfer control station and control center combination, the focus adjustment to achieve the heating of public buildings. Heat transfer station controller using ACX32 collection pipe network with a heating system, secondary supply and return water pipe network pressure, temperature, outdoor temperature and other parameters, the best obtained through the operation controller PID control scheme to regulate the solenoid valve to open a network degrees to achieve the water temperature control. Installed in all buildings by controlling the shut-off valves, to achieve a stage in the building without heating, by closing the throttle to return the excess heat water, return water temperature to improve the secondary network, reduce the heat supply to save energy. Design data is divided into two parts, one is the heat transfer station site collection of data transmission via Ethernet ring network to the monitoring center, on the other hand, the monitoring point spread, classrooms, libraries and other public buildings, the buildings of the shut-off valves real-time data and control data transmitted to the monitoring center through the GPRS. Aspects of the d
