when the metering equipment is any one of a water meter, a gas meter and a heat meter, the daily energy intensity period statistical maximum value of the metering equipment is calculated according to the maximum value of all current flow rates acquired in the current day period, the monthly energy intensity period statistical maximum value is calculated according to the maximum value of all current flow rates acquired in the current month period of the water meter, and the user standard energy value per second is calculated according to the maximum flow rate;
the event judging unit is used for generating an event that the statistical maximum value of the energy consumption intensity period of the metering equipment exceeds a limit value when the statistical maximum value of the energy consumption intensity period exceeds the limit value at the end of each month of continuous 2 months; the level of the event is the ratio of the statistical maximum value of the monthly energy intensity period of the metering equipment to the standard energy value per second of the user;
the metering equipment comprises an electric energy meter, a water meter, a gas meter and a heat meter; the event judging unit counts the event that the maximum value of the energy consumption intensity period exceeds the limit value aiming at one or more metering devices of the same user; the level of the event corresponding to the user is the sum of the maximum level of the event with the maximum value of the statistics of the energy consumption intensity period exceeding the limit value in each type of metering equipment and the product of the type weight of the metering equipment;
the weight of the electric energy meter is 1.6, the weight of the water meter is 1.2, the weight of the gas meter is 1.2, and the weight of the heat meter is 1.
