[0002] At present, in the central heating system and the heating of buildings and households, most of the heating charges are collected according to the user's heating area.

[0021] Embodiment 1:

[0022] like Figure 1 As shown, this embodiment provides a schematic diagram of a heating system control device for heating control, including: an electric control valve, a flow sensor, a temperature acquisition module, a single-chip microcomputer, a memory, a power supply, a display, a keyboard and a communication module, wherein the keyboard is electrically connected to the display, the power supply and the display are electrically connected to the single-chip microcomputer, and the power supply provides power for the control device system. The temperature acquisition module includes a plurality of temperature sensors, which are respectively fixedly installed at preset positions, the temperature acquisition module, the electric control valve, the communication module, the memory, and the flow sensor are respectively connected to the single-chip microcomputer for communication, and the single-chip microcomputer receives temperature data and flow data collected by the plurality of temperature sensors and flow sensors at preset positions through the communication module, controls the electric control valve to switch the water supply pipeline or the return pipeline according to the collected temperature data and flow data, and stores the collected data in the memory.

[0023] The temperature acquisition module includes a return water temperature sensor, a water supply temperature sensor, an indoor temperature sensor and an outdoor temperature sensor. The return water temperature sensor and the water supply temperature sensor are connected to the single chip microcomputer through a communication module. The water supply temperature sensor is fixedly installed on the inner wall of the water supply pipeline, and the return water temperature sensor is fixedly installed on the inner wall of the return water pipeline. The indoor temperature sensor is installed at a preset position indoors, and the outdoor temperature sensor is installed at a preset position outdoors. The indoor temperature sensor and the outdoor temperature sensor are connected to the single chip microcomputer through a communication module.

[0024] When in use, various data are collected in real time (including data obtained from the electric control valve, flow sensor and temperature acquisition module), and the real-time data and set data are transmitted to the single-chip microcomputer through the communication module. The single-chip microcomputer calculates the control strategy with the real-time data and the set data, and sends it to the local or remote display for real-time display after the control processing.

[0025] Specifically, the flow data signal, supply and return water temperature data signal, and indoor and outdoor temperature signals collected by the flow sensor, return water temperature sensor, supply water temperature sensor, indoor temperature sensor, and outdoor temperature sensor are sent to the single-chip microcomputer for processing. The single-chip microcomputer calculates the supply and return water temperature difference, indoor and outdoor temperature difference, and flow rate used by the user based on the flow data signal and each temperature data signal. When the room temperature and calorific value used by the user reach the preset value, the single-chip microcomputer drives the electric control valve to work. This application automatically adjusts the user's heating amount based on the heating curve corresponding to the supply and return water temperature difference, indoor and outdoor temperature difference, and the average value of outdoor temperature and indoor temperature. The calculation formula for regulation is:

[0029]

[0030]

[0031]

[0032] Where, t p Indicates the average temperature of supply and return water, t g Indicates the water supply temperature, t' g Indicates the preset water supply temperature, t' h Indicates the return water temperature, t' h Indicates the preset return water temperature, △t indicates the supply and return water temperature difference, △'t indicates the preset supply and return water temperature difference, t n represents room temperature, t' n Indicates the preset room temperature, t w represents the external temperature, t' w represents the preset external temperature, f represents the actual flow rate, f' represents the preset flow index B = 0.35 (can be found in the appendix of the heating project), It indicates the ratio of actual flow rate to design flow rate. The angle code “′” is the design parameter.

[0033] For the system that needs to be regulated, the supply and return water temperatures of the heating network under different outdoor ambient temperatures can be obtained from the above to obtain the corresponding relationship between tg and th at several different temperature differences (Δt), and the heating curve can be obtained. The corresponding relationship between the water supply temperature and the outdoor temperature can be obtained based on the obtained curve. The slope characteristic (0.2-3.2 slope) in the classic characteristic curve can be changed by changing the slope and intercept parameters to make the heating characteristic curve suitable for different application scenarios.

[0034] As an embodiment of the present application, for business places, schools, and government offices, the instructions for heating in different time periods and regions can be input remotely locally, and the thermal inertia of the building can be used to schedule the heating control system of the present application in advance or in a delayed manner. During the heating period, the regulating electric control valve (electric control valve) is automatically opened in advance to make the heating supply reach the room temperature set value. During the time period when heating is not required, the electric control valve is closed, and the electric control valve is automatically reduced or closed in advance to reduce or stop the heating supply. The system automatically and intelligently controls and uses heat reasonably. The heating system is regulated according to the outdoor temperature, the return water temperature, and the indoor temperature to achieve the purpose of automatic operation and energy saving.

[0035] It should be noted that the calculation formula for regulation is existing technology, and its source is "Planning Textbook for Architectural Environment and Equipment Engineering Major in Colleges and Universities, Heating Engineering (Fourth Edition)".

[0036] Compared with the existing heating system, the advantages thereof are that the heating system of the present application can realize the control of the end of the heat demand side and the autonomous operation when the remote master control system fails.
