The invention relates to the field of intelligent control, and discloses a building heating valve centralized control system. The building heating valve centralized control system comprises a temperature detection module, at least one microprocessor, a monitor terminal and an execution module. The temperature detection module comprises a plurality of temperature sensors, and the temperature sensors are arranged heating water inlet pipes of dwelling units and used for detecting the temperature of a heating water inlet pipe; the microprocessors are connected with the temperature detection moduleand used for receiving data of the temperature detection module and judging the opening and closing of corresponding heating valves; the monitor terminal is connected with the microprocessors and used for displaying opening and closing situations of the heating valves of the dwelling units and sending control signals to the execution module according to requirements; and the execution module receives the control signals sent by the monitor terminal and controls the opening and closing of the heating valves connected with the execution module. According to the building heating valve centralized control system, operators on duty of the monitor terminal id only required to monitor the opening and closing of the heating valves of a whole building, manpower is greatly saved, and reduction of costs and improvement of the efficiency are facilitated.
