Energy management control method and system based on energy consumption historical data analysis

The invention provides an energy management control method and system based on energy consumption historical data analysis. The method comprises steps of: A, acquiring current energy consumption information and historical energy consumption data of a specific monitoring point; B, generating a corresponding energy use plan according to the historical energy consumption data of the monitoring point; giving an early warning signal when the current energy consumption information of the monitoring point satisfies an early warning condition, wherein the early warning condition is that an computed energy use curve cannot complete the energy use plan according to the current energy consumption information; and D, sending an alarm signal when the current energy consumption information of the monitoring point reaches a limit value of the energy use plan. The method may effectively analyze energy consumption by acquiring the historical energy consumption data and the current energy consumption information, sets the corresponding energy use plan, and timely adjusts the energy consumption case of equipment by sending the early warning signal.
