ELECTRIC ENERGY MONITORING APPARATUS, AN ELECTRIC ENERGY MONITORING SYSTEM, AN ELECTRIC ENERGY MONITORING METHOD, A CONTROL PROGRAM AND A RECORDING MEDIUM, CAPABLE OF JUDGING EXCESS OF USED ELECTRIC ENERGY OF A PLURALITY OF ELECTRIC DEVICES

摘要

PURPOSE: An electric energy monitoring apparatus, an electric energy monitoring system, an electric energy monitoring method, a control program and a recording medium are provided to inform judged alarm content to a user with high accuracy.;CONSTITUTION: An electric energy monitoring apparatus (1) includes an alarm level difference calculation unit (23), an alarm judgment value calculation unit (24), a judgment unit (25) and an output unit (27). The alarm level difference calculation unit calculates alarm level difference which is difference between used electric energy collected by a counting unit (22) per collection unit and a predetermined alarm level value per collection unit. The alarm judgment value calculation unit calculates an alarm judgment value on the ground of the alarm level difference of each counting unit calculated by the alarm level difference calculation unit. The judgment unit judges whether the alarm judgment value calculated by the alarm judgment value calculation unit exceeds a predetermined alarm threshold. The output unit outputs alarm information indicating that the used electric energy within the monitoring range is exceeded, when the judgment unit judges that the alarm judgment value exceeds the alarm threshold.;COPYRIGHT KIPO 2013;[Reference numerals] (1) Electric energy monitoring apparatus; (11) Control unit; (12) Memory unit; (13) Data input unit; (14) Operation unit; (15) Communication unit; (21) Data obtaining unit; (22) Data counting unit; (23) Alarm level difference calculation unit; (24) Alarm judgment value calculation unit; (25) Judgment unit; (26) Contribution calculation unit; (27) Alarm transmission unit; (28) Data setting unit; (31) Count unit information; (32) Alarm level value information; (33) Influence information; (34) Alarm threshold information; (35) Time coefficient information
