Heating household valve adjusting method, system and equipment based on GBDT

Abstract

The invention discloses a heating household valve adjusting method and system based on GBDT. The method comprises the following steps of 1, obtaining historical heating data and historical meteorological data, carrying out the data integration of the above data with the time as the benchmark, forming synthetic data, and building a GBDT model through the synthetic data; 2, adjusting model parameters of the GBDT model to obtain an optimal prediction model; 3, processing the meteorological data of the to-be-predicted day and the heating data except the heat supply flow, inputting the processed data into the optimal prediction model, and obtaining the predicted heat supply flow of the to-be-predicted day; and 4, serving the predicted heat supply flow as a set value of a PID control algorithm,and controlling the opening degree needed by a heat supply household valve. According to the method, through the combination of GBDT and PID algorithms, the heat supply amount of a user is accuratelycontrolled.

Description

technical field [0001] The invention relates to the heating field, in particular to a GBDT-based heating household valve adjustment method, system and equipment. Background technique [0002] With the development of the national economy and the advancement of urbanization, the construction area of ​​cities and towns in northern my country continues to increase, and the area of ​​central heating also increases rapidly. [0003] Most of the heating systems in my country still adopt the backward and extensive control method, that is, the water supply temperature of the heat exchange station is determined only based on the outdoor temperature or based on experience, and the feedback adjustment is performed according to the return water temperature or not at all. [0004] Most of the heating household valves in the prior art do not have the flow regulating function. [0005] In the more advanced existing technology, the opening of the heating household valve is mainly adjusted b...

AI Technical Summary

Problems solved by technology

[0005] In the more advanced existing technology, the opening of the heating household valve is mainly adjusted by the PID control algorithm, and it is necessary to set the tracking flow value for the PID control algorithm; but the tracking flow value can only be manually set according to experience, resulting in this The tracking flow value is inaccurate, and it cannot be dynamically adjusted according to meteorological data and heating data, nor can it consider the impact of the user's heat usage habits on the tracking flow value
