Problems solved by technology

[0003] The existing heating system control unit cannot automatically adjust the time required for the system to start in advance according to the heating system control unit and the indoor and outdoor temperature of the building. If the time setting is too large, the system will run at high speed prematurely, wasting energy; time setting is too small, the indoor temperature cannot reach the set value within the specified time

Abstract

The invention relates to a heat supply energy saving control method and system based on neural network prediction. The heat supply energy saving control method comprises the following steps that (S1) a neural network prediction model is built; and (S2) a heat supply system control unit is controlled through the neural network prediction model to enable a building to reach an anticipant room temperature at set time. Through a remote communication unit and a task control unit, users can set the temperature demands of the building locally or through remote equipment, that is, the indoor temperature reaches the set temperature at the appointed time. The control method and system, provided by the invention, can predict optimal advance starting time of a heat supply system according to the operation history data of the heat supply system and the hot water flow, the hot water temperature, the indoor temperature and the outdoor temperature at the present time, finishes the starting of the heat supply system through a heat supply system control unit to realize reduction of the energy consumption under the precondition of satisfying the heat supply demands, and is excellent in economic benefit and social benefit.

Description

technical field [0001] The invention relates to a heating energy-saving control method and system based on neural network prediction, which can realize the prediction of the time required for a building from the start of heating to the indoor temperature heating to a set value during the heating process, and through the heating The control of a system control unit realizes model predictive control of building heating, and belongs to the technical field of heating energy saving research. Background technique [0002] With the improvement of people's living environment requirements, heating system control units are used in a large number of buildings in cold winter cities. For commercial office buildings, government office buildings, schools and other buildings, the heating time and heat load vary greatly with time, and the continuous operation of the heating system consumes a lot of energy. Therefore, intermittent heating is required for different buildings. Optimize control...
