<p>PROBLEM TO BE SOLVED: To provide an electric apparatus management device capable of easily recovering a built-in microcontroller into a normal state if the microcontroller abnormally operates.SOLUTION: In an electric apparatus management device 70, a power supply line 16 is provided between a first connection part 12 to which power is supplied from the outside, and a second connection part 14 for connecting with a power supply line of a corresponding electric apparatus. A current detection section 34 detects a magnitude of a current flowing in the power supply line 16. A microcontroller 36 periodically transmits information relating to a detection result of the current detection section 34 by means of a radio transmitter 38. The microcontroller 36 is operated by an external supply power source or a secondary battery. On the basis of a change in a voltage of the power supply line 16, a power supply detection section 40 detects start or end of power supply from the outside through the first connection part 12 and outputs a reset signal to the microcontroller 36 in the timing of at least either the start or the end of power supply from the outside.</p> |
