Smart electric distributing system and method using home hub device

The present invention relates to a smart electric distribution system using a home hub device and an operation method thereof. The smart electric distribution system using a home hub device comprises: a home appliance including a wireless communication unit for transmitting an operation signal; a distribution board configured to detect a current amount of at least one line to which the home appliance is connected and generate and transmit power consumption information according to the current amount; and a home hub device including a control unit, a wireless communication unit configured to form a communication link with the home appliance and the distribution board through a short-range wireless communication network, a memory connected to the control unit, a speak configured to output voice information, and a unique function unit configured to implement unique functions of the home appliance. The memory of the home hub device stores instructions. The instructions, when executed, allow the control unit to: store the power consumption information received from the distribution board in the memory; calculate estimated power consumption according to the operation signal received from the home appliance; determine whether the estimated power consumption is equal to or greater than a predetermined threshold power consumption; transmit an operation acceptation signal which allows operation of the home appliance to the home appliance via the wireless communication unit when the estimated power consumption is lower than the predetermined threshold power consumption; transmit a no-operation signal which disallows operation of the home appliance to the home appliance via the wireless communication unit when the estimated power consumption is equal to or greater than the predetermined threshold power consumption; and output the no-operation information in a voice form through the speaker. According to the present invention, it is possible to prevent blackout caused by short-circuit current or overcurrent. 본 발명은, 작동 신호를 전송하는 무선통신부를 포함하는 가전 기기; 상기 가전 기기가 연결된 적어도 하나의 배선에 대한 전류량을 감지하고, 상기 전류량에 따른 소비 전력 정보를 생성하여 전송하는 분전반; 및 제어부와, 상기 가전 기기 및 상기 분전반과 근거리 무선 통신망을 통해 통신 링크를 형성하는 무선통신부와, 상기 제어부와 연결된 메모리와, 음성 정보를 출력하는 스피커와, 고유한 자체의 가전 기능을 수행하는 고유기능부를 포함하는 홈 허브 디바이스를 포함하여 구성되고, 상기 홈 허브 디바이스의 메모리는 인스트럭션들을 저장하고, 상기 인스트럭션들은, 실행될 경우, 상기 제어부가: 상기 분전반으로부터 수신된 소비 전력 정보를 상기 메모리에 저장하도록 제어하고; 상기 가전 기기로부터 수신되는 작동 신호에 따라 예상 소비 전력을 계산하고; 상기 예상 소비 전력이 미리 설정된 임계 소비 전력 이상인지 판단하고; 만약 상기 예상 소비 전
