    • A detection apparatus (102) connected to a device in a residence and an electricity meter (100) indicating an amount of electric power consumed by the device in the residence, the detection apparatus (102) including: a reception unit (1021) which receives the amount of electric power from the electricity meter (100); a collection unit (1024) which collects usage status of the device; a device information holding unit (1027) which holds device information including the usage status of the device and electric power consumption of the device corresponding to the usage status; and a determination unit (1025) which determines whether or not the electricity meter (100) is tampered, by comparing an estimated electric power consumption amount with the amount of electric power received by the reception unit (1021), the estimated electric power consumption amount being estimated from the usage status of the device by using the device information, in which the determination unit (1025) determines that the electricity meter (100) is tampered, when a difference between the estimated electric power consumption amount and the amount of electric power received by the reception unit (1021) is equal to or more than a predetermined threshold.
    • 一种连接到住宅内的装置的检测装置(102)和表示该住宅内的装置消耗的电力量的电表(100),检测装置(102)包括:接收部(1021),其接收 来自电表(100)的电力量; 收集单元(1024),其收集所述设备的使用状态; 装置信息保持单元,其保存包括与所述使用状态对应的所述装置的使用状态和所述装置的电力消耗的装置信息; 以及确定单元(1025),其通过将估计的电力消耗量与由所述接收单元(1021)接收的电力量进行比较来确定所述电表(100)是否被篡改,所述估计电力消耗量 通过使用其中确定单元(1025)确定电表(100)被篡改的设备信息,根据估计的电力消耗量和电力量之间的差异来估计设备的使用状态 由接收单元(1021)接收的信号等于或大于预定阈值。
