Electric energy monitoring device, electric energy monitoring system, electric energy monitoring method, control program, and recording medium

摘要

The present invention, to reflect, for example, use conditions or characteristics of the plurality of electric devices included in the monitoring range, and is used to determine the presence or absence of the excess power amount used of the plurality of electric devices included in the monitoring range. Electric power of the present invention, monitoring apparatus includes a plurality of electric devices included in the monitoring range by classification into a plurality of aggregated unit, and each of its aggregation unit, data collection unit 22 for counting the use of electric power of the electric device, respectively, aggregate use amount of power, and the warning level car alarm level difference calculating section 23 for calculating a difference between the warning level value, based on the alert level difference of each aggregation unit calculates alarm determination value for calculating the alarm determination value unit 24 , alarm determination value for transmitting alarm information indicating that the year when the over whether determination section 25, more than the alarm threshold value and determines that whether or not a predetermined alarm threshold value, used in the monitoring range power is greater than the notification device equip the alarm transmitter (27). ;
