Multipurpose smart switchboard device and system, and operation method thereof

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.

An operation method of 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, the operation method comprising:

• detecting whether at least one of heat, smoke, and gas having a value greater than or equal to a predetermined reference value is generated;
• when it is detected that the at least one of heat, smoke, and gas having the value greater than or equal to the predetermined reference value is generated, turning the first relay device off;
• and
• when the generated at least one of heat, smoke, and gas having the value greater than or equal to the predetermined reference value is eliminated, turning the first relay device on.
