[Abstract]:The research of this subject is based on Siemens S7-1200 controller, combined with HVAC engineering, computer technology, automation technology and communication technology to complete the remote monitoring of heat exchange station of water water system.Using Siemens WinCC OA platform software to collect, file and analyze the data of all the heat exchange stations that implement the automatic control system.At the same time of single heat exchange station data remote transmission, station control, realize the real-time monitoring of the whole heat network hydraulic condition, and then complete accurate data transmission and heat distribution from the station to the waterline, in order to achieve manpower, resources, energy saving,Get the maximum economic benefit.This paper chooses the heat exchange station of the Civil Affairs Bureau to design and implement the automatic control system in the station. After the implementation of the system, the remote monitoring of the temperature, pressure, flow, heat and other data of the primary network and the secondary network in the station will be realized.Because of the large number of stations, the large amount of data communication in the control system and the large number of control loops, the stability, reliability and efficiency of the remote communication network and the control system are required.In addition, the control system adopts Siemens Smart 700 touch screen as the field interactive interface. The two systems constitute a field independent monitoring system, which can be operated in place and save the operation parameters without remote monitoring system.This paper focuses on the design of automatic control system architecture and scheme, the realization of automatic control function.Finally, the operation data of a heating station in the heating season collected by the automatic control system are analyzed, and the energy saving effect of the automatic control system can be seen by the magnitude of the heat consumption of the heating system.
