Distributed electric control system of heat exchange station

The invention provides a distributed electric control system of a heat exchange station and relates to electric control systems of the heat exchange station. The distributed electric control system aims at solving the problems that according to an electric control system of an existing heat exchange station, a centralized control structure is adopted, the application range is narrow, the working manner is not flexible, and partial modification can not be conducted. The distributed electric control system comprises an upper system, an intelligent control unit, a communication bus, a water replenishing unit, a circulating unit and a thermotechnical unit, wherein the output end of the intelligent control unit is connected with an electrically operated valve and a pressure pump; the output end of the water replenishing unit is connected with a water replenishing pump and an electromagnetic pressure release valve, and the output end of the circulating unit is connected with a circulating pump; the output end of the thermotechnical unit is connected with a thermodynamic instrument and a regulating valve, and the upper system establishes connection with the intelligent unit through a GPRS network or an industrial ethernet network; and the intelligent control unit is connected with the water replenishing unit, the circulating unit and the thermotechnical unit through the communication bus. The distributed electric control system is wide in application range and flexible in working manner.
