Claim 7:
8. A multipurpose smart switchboard system comprising:
a multipurpose smart switchboard device including a camera device connected to a lead-in wire, a main breaker connected to the camera device, a first relay device connected between the main breaker and a first load which uses a constant power source, a second relay device which is connected to the first relay device and controls all breakers except for a breaker for the constant power source, a third relay device which is connected to the second relay device and controls all the breakers except for the breaker for the constant power source, a fourth relay device which is connected between the third relay device and a second load including a general power consumption device and controls all the breakers except for the breaker for the constant power source and a breaker for a temperature regulation device, and a fifth relay device which is connected between the third relay device and a third load including a temperature regulation device and controls the breaker for a temperature regulation device; and
a power system operating institution from which power is supplied to the multipurpose smart switchboard device through the lead-in wire,
wherein the power system operating institution communicates with the multipurpose smart switchboard device through a power line communication circuit and controls a power operation of an energy management system (EMS) for power demand management or blackout prevention by controlling the second relay device.
