ELECTRIC APPARATUS MANAGEMENT SYSTEM, POWER RECEPTACLE, AND POWER PLUG

摘要

PROBLEM TO BE SOLVED: To make it possible to manage a state of an electric apparatus with a simple configuration without requiring an external power source.SOLUTION: First and second piezoelectric elements 25, 26 are successively provided along a depth direction of a receptacle insertion port 21 inside a power receptacle 20. At a periphery of an insertion blade 12 of a power plug 10, a protrusion 15 which presses a pressing surface when being inserted/extracted to/from a power receptacle 20 is formed and a radio IC tag 14 in which a plug ID is stored is provided. The power receptacle 20 includes: a reader 27, operated with generated power of a piezoelectric element 26, for reading the plug ID from the radio IC tag 14; and a radio device 28, operated with the generated power of the piezoelectric element 25, 16, transmitting a radio signal including the plug ID read by the reader 27 and a receptacle ID of the power receptacle 20. A management device 50 manages information concerning an electric apparatus 3 on the basis of the receive plug ID and the receptacle ID.SELECTED DRAWING: Figure 4
