Therefore, in today's energy-short society, building heating energy conservation has become a very urgent issue.

Heat meter 1 adopts a heat meter with an automatic totalizer.

The electric regulating valve 3 is used to realize the continuous regulation of the flow. Two kinds of control can be realized: one is simple control, which only controls the opening and closing of the two-way valve; the other is complex control, which controls the opening, closing, opening direction and opening degree of the two-way valve, and the flow rate can be controlled by itself.

Intelligent thermostat 9 adopts central air-conditioning liquid crystal intelligent thermostat.

The working principle of the utility model is as follows:

Two temperature sensors 2 connected with the heat meter 1 measure the temperature of the supply and return water respectively. According to the temperature difference between its supply and return water and the flow of hot water flowing through the heat meter 1, the heat meter 1 calculates the heat dissipation of the radiator 4, that is, the heat supply at the end. The temperature sensor 2 placed in the room 6 measures the room temperature, and transmits it to the single-chip microcomputer 5 together with the temperature set by the intelligent thermostat 9 or the wireless communication module 10. The intelligent thermostat 9 can be set by buttons or by wireless communication. Remote setting of the device (within the service scope), as shown in Figure 1, the smart thermostat 9 is connected to the wireless communication module 10 to realize wireless and intelligent control of the room temperature. The single-chip microcomputer 5 controls the electric valve 3 to change the opening degree and direction of the valve through processing the information, so as to realize the continuous control of the flow.

According to the general schematic diagram and partial structural diagram, the terminal controller of the heating system of the utility model is divided into three units: one is the control unit, which is composed of a single-chip microcomputer 5 and an intelligent temperature controller 9 . The measured temperature of the temperature sensor 2 and the set temperature of the thermostat 9 and the module 10 are converted by the signal converter, read by the single-chip microcomputer 5 and processed by its internal central processing unit, and drive the two-way electric valve 3 to change the opening degree and direction; the second is the actuator unit, including the two-way electric valve 3, whose function is to receive the driving information from the single-chip microcomputer to complete the operation of adjusting the heating flow. The third is the controlled object unit, that is, the actual indoor temperature, wherein the wireless setting of the indoor temperature is realized through the intelligent temperature controller 9 or the wireless communication module 10 .

Referring to Fig. 2, send a signal to the wireless communication module 10 or manually press the button to set the temperature of the intelligent thermostat 9 through the wireless communication device, set a lower temperature when there is no one in the room, and set a higher temperature when there is someone. The terminal temperature actually measured by the temperature sensor 2 and the temperature set by the intelligent thermostat 9 or the wireless communication module 10 are input to the single chip microcomputer 5 after being passed through the signal converter. The central processing unit of the single-chip microcomputer 5 runs the program of the utility model to complete data storage, transmit real-time status information to the color display screen, and drive the two-way electric valve to change the opening and direction. The stored data can be uploaded to the heating control center to provide data basis for household heat metering.

In Fig. 3, the control system of the present invention is composed of a single-chip microcomputer input and output module, an automatic regulating valve, a controlled room and a temperature sensor. Each component forms a closed-loop transmission system, and the measured temperature of the temperature sensor is fed back to the comparison point, and is sent to the input module of the single-chip microcomputer together with the temperature set by the intelligent thermostat and the wireless communication module. It is known from classical control theory that the system can achieve good stability.

In FIG. 4 , the mode selection is "wireless control", and the wireless communication module 10 sets the indoor temperature of the room 6 through wireless communication signals. If the actual temperature measured by the temperature sensor 2 in room 6 is equal to the set temperature, the opening of the two-way electric valve remains unchanged, the heating flow remains unchanged, and the program ends; if the actual temperature measured by the temperature sensor is not equal to the set temperature, the two-way The electric valve opening changes continuously, and the heating flow changes accordingly. After a certain time step, check again whether the measured temperature reaches the set temperature. If not, the valve opening continues to change continuously until the two temperatures are equal, and the program ends.
