Heating user valve adjusting method and system based on artificial intelligence and equipment

The invention discloses a heating user valve adjusting method and system based on artificial intelligence. The adjusting method comprises the following steps that whether historical data of a specificuser exist in a database or not is judged, the data scale is judged; if the historical data of the user are large data, the optimal prediction model based on the LSTM time sequence is used for obtaining the heat supply flow to be predicted; if the historical data of the user are small data, an optimal prediction model based on GBDT or a gray time sequence is used for obtaining predicted heat supply flow; if the historical data of the user do not exist, the historical data of other users closest to the user from the database are found out in a feature clustering mode, the corresponding optimalprediction model is selected according to the scales of the historical data of the other users to obtain the predicted heat supply flow; and the predicted heat supply flow serves as a tracing flow value of a PID control algor
