Method and system of heat network energy consumption index analysis and early warning based on BP neural network

The invention relates to the field of energy consumption analysis and prediction of a heat supply system, and particularly relates to a method and system of heat network energy consumption index analysis and early warning based on a BP neural network. The method of the heat network energy consumption index analysis and early warning based on the BP neural network comprises the following steps thatthe working condition data is collected; the working condition data is processed; energy consumption indexes in real time are calculated according to the processed working condition data, and the energy supply situation of the heat network is analyzed; the energy consumption indexes are predicted according to a prediction model; and early warning is carried out on the operation energy consumptionof the heat supply system according to the real-time energy consumption indexes and the predicted energy consumption indexes, and online analysis and comparison are performed on the energy consumption indexes, the energy cons
