Step 303: store the data that step 302 collects to memory module;
Management control method of the present invention can be divided into following two management modes, one of them:
Step 304: the data computation processing module is carried out the average power consumption values that analyzing and processing draws unit output in certain monitoring time to the data of 202 collections;
Draw the electric energy consumption in the monitoring time T, the electric energy consumption of formula (2) unit of drawing output by formula (1).Wherein
W TElectric energy consumption in the-monitoring time T
N-Output total amount in the monitoring time
W SingleUnit output average power consumption in the-monitoring time;
Step 305-1: result and the unit output criteria power consumption values with same external conditional parameter by step 304 compare, and according to difference allowed band δ %, judge whether the duty of energy load equipment and energy consumption be unusual;
Step 306 if unit output actual consumption and unit output criteria energy consumption difference exceed allowed band δ %, is then sent corresponding warning information by alarm module by 305 judged result, and is higher in this time period like unit output energy consumption;
