ELECTRICITY SUPPLY DEVICE AND ELECTRICIY SUPPLY SYSTEM

摘要

[Problem] To provide an electricity supply device with which it is possible to prevent the illegitimate use of an identification code without assigning an identification code to the load to which power is to be supplied. [Solution] An electricity supply device (10) is equipped with: an electricity supply-side connection unit (1) electrically connected to an electricity reception-side connection unit of a load; a switch unit (2) that opens/closes an electrical circuit between a power line (300) and the electricity supply-side connection unit (1); a first IP network connection unit (4) for connecting to an IP network (400); an IP address storage unit (5) that stores a first IP address of this device; a first storage unit (6) that stores first identification information for a mobile communication terminal; a display unit (7) that displays on a video screen identifiers specifying the resources of the IP network (400) as identification codes; and a first control unit (8) that turns on the switch unit (2) on the basis of the first identification information, and that changes the identification code displayed on the display unit (7) to another identification code with a prescribed timing.
