The invention provides a secondary network valve opening degree control method and system. The method comprises the steps that a first collection control valve acquires the water delivery flow, the water delivery temperature, the water delivery pressure and a first valve opening degree value of a secondary network and sends the water delivery flow, the water delivery temperature, the water delivery pressure and the first valve opening degree value to a cloud server; a second collection control valve acquires the return water flow, the return water temperature and the return water pressure of the secondary network and sends the return water flow, the return water temperature and the return water pressure to the cloud server; the cloud server presets a return water constant temperature interval, calculates a return water temperature compensation value according to data uploaded by the first collection control valve and the second collection control valve, calculates a valve opening degree adjustment value according to the return water temperature compensation value, generates a valve opening degree adjustment instruction and sends the valve opening degree adjustment instruction to the first collection control valve; and the first collection control valve responds to the valve opening degree adjustment instruction, and the valve opening degree is adjusted to be the second valve opening degree value. In this way, the problem that heat supply of the secondary network is unbalanced can be solved, efficient and reasonable control over the valve of the secondary network is achieved, and the heat supply temperature of the secondary network reaches the standard and is balanced.
Description
technical field [0001] The present invention generally relates to the field of urban heating, and more specifically relates to a method and system for controlling the opening of a secondary network valve. Background technique [0002] The most important difference between urban smart heating and traditional heating is that it pays more attention to user needs and the quality of heating service; that is, it is changed from meeting the overall heating demand initiated by heat sources to meeting the heating needs of different individuals. a means of control; [0003] The heating system is composed of "source-network-end". Some original mature products and technologies, such as "heat source energy-saving operation monitoring", "multi-heat source linkage control", "primary network balance control", "heat exchange Station unattended", "full heating network simulation technology", etc., all meet the overall heating demand, but from the heat exchange station to the user's indoor pa...
