Embodiment approach 1

[0028] refer to Figure 1 to Figure 11 Embodiment 1 of the electric energy metering device concerning this invention is demonstrated. In addition to the original function of the energy metering device, that is, the function of measuring and measuring the power supply and power consumption to installed users (households, factories, etc.), the energy metering device of this embodiment also has a wireless The communication function can form a wireless mesh network through the wireless communication function. In addition, information such as the measured electric power is sent to the data acquisition device via the wireless mesh network. When receiving / transmitting various information with other devices having a communication function (data collection devices, other energy metering devices, etc.), it is also performed via a wireless mesh network.

Embodiment approach 2

[0071] An electric energy metering device according to Embodiment 2 will be described. In addition, the structure of the communication network formed by the electric energy metering device, the wireless mesh system, the data acquisition device, and the electric energy metering device is the same as that of Embodiment 1 (refer to Figure 1 ~ Figure 4 ).

[0072] use Figure 12 The theft detection operation performed by the electric energy metering device 5 of the present embodiment will be described. Figure 12 It is a figure which shows an example of the theft detection procedure by the electric energy metering apparatus 5 of Embodiment 2. For the theft detection operation described in Embodiment 1 ( Figure 5 ) for general processing, labeling and Figure 5 Same step number, and omit description.

[0073] The theft detection operation performed by the electric energy metering device 5 of the present embodiment is performed by inserting step S31 between steps S12 and S13 ...

Embodiment approach 3

[0085] An electric energy metering device according to Embodiment 3 will be described. In addition, the structure of the communication network formed by the electric energy metering device, the wireless mesh system, the data acquisition device, and the electric energy metering device is the same as that of Embodiment 1 (refer to Figure 1 ~ Figure 4 ).

[0086] use Figure 16 The theft detection operation performed by the electric energy metering device 5 of the present embodiment will be described. Figure 16 It is a figure which shows an example of the theft detection procedure by the electric energy metering apparatus 5 of Embodiment 3. For the theft detection action described in Embodiments 1 and 2 ( Figure 5 , Figure 12 ) for general processing, labeling and Figure 5 , Figure 12 Same step number, and omit description.

Abstract

The present invention is an electricity meter that forms, with one or more data collection devices for collecting electrical energy consumption data, a wireless mesh network, the electricity meter being provided with: a wireless communication means (wireless unit (51), data relay processing unit (53)) for transmitting the amount of electricity consumed by a customer to the data collection device selected as a data transmission destination, the transmission being performed directly or via another adjacent electricity meter; a wireless communication controller (57) for determining whether or not the home device has moved on the basis of the presence or absence of a variation in the number of adjacent electricity meters and in the reception level of a signal transmitted from each of the adjacent electricity meters; and a switch (62) for discontinuing the operation of the circuit supplying power to the customer if it is determined that the home device has moved.

Description

technical field [0001] The invention relates to an electric energy metering device for metering electric energy and the like. Background technique [0002] Electric energy metering devices are installed by electric power companies in consumers' homes and factories to measure and measure used electric energy, current, and other electric power. In view of the occasional electricity theft, the existing electric energy metering device detects the current on the upstream side and the downstream side of the distribution line connected to the electric energy metering device, and uses the difference to detect the electricity theft. Among them, the so-called theft Electricity refers to an act of disguising already used electric energy and reducing requested electricity bills by performing improper wiring on the electric energy measuring apparatus after installing the electric energy measuring apparatus (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese P...
