The present invention connects the distribution panel to the home network by using power line communication, measures current, voltage, and leakage current, and can alarm when overcurrent, leakage current, high temperature, door is opened, and alarms the user with a wired telephone when the set value is abnormal. It can be a system. In addition, by enabling the power amount calculation and the electricity bill calculation in real time, it is also possible to raise the alarm on the user's electricity consumption.

In general, a cabinet panel refers to a lead wire that is drawn through a power meter at the entrance of a house where the lead wire is drawn, and is composed of a main switch for all wiring in the indoor, a fuse, and a circuit breaker of each branch circuit branched therein. . Distribution boards are an essential part of the electrical installation and should be carefully placed in their position or height and installed so that wiring costs are low. In recent years, it is aesthetically desirable to avoid places where the distribution boards are prominent in residential houses such as entrances, lobbies and halls. An embedded distribution panel that selects a place where instruments or furniture are not placed and purchases the distribution panel into the wall is widely used.

However, in the conventional distribution board, the opening and closing operation of the circuit breaker (NFB) or the earth leakage breaker (ELB) is performed solely by manual operation of the electric facility manager or the electric user, so that the electric leakage state, load state, input power state, There was an inconvenience in that the user could not monitor the power failure and the constant monitoring of the circuit breaker in real time. In addition, there is no separate wired / wireless communication modem and dedicated controller in the electric distribution board, so when remote control or automatic control is required, an electronic switch or relay modem and accessories separately from the circuit breaker (NFC) or the circuit breaker (ELB) are required. After the installation, there was a way to control the opening and closing on / off. Most of the current distribution panel has a problem such that if a manual operation is not properly performed the operation of the earth leakage breaker installed in the distribution panel, a fire is caused by a short circuit, resulting in human injury and property loss.

The present invention relates to an intelligent distribution board that connects to a home server using power line communication, and can establish a digital distribution board and an intelligent home server network to manage the distribution board through a home network and a service that notifies alarms and telephone calls when an abnormality occurs.

Here, the external device includes a current transformer (CT), instrument transformer (PT), image transformer (ZCT), the temperature sensor for measuring the indoor temperature for measuring the electrical consumption; A door lock / open monitoring sensor is included, and the control unit analyzes and calculates data on voltage, current, leakage current, room temperature check, door lock check, and communication state for a predetermined time to generate a system error or fire risk. It includes a processing unit (MPU) for predicting the. Next, in order to enable system management and information exchange with the home server, the power line communication (PLC) modem installs the same modem in the home server to enable two-way communication, and prevents the carrier from passing to the neighboring house when using the power line communication. In order to achieve this, it is desirable to filter the signal below 40 dB using a B / F (Blocking Filter). The display unit of the system is composed of a display window and an operation button that displays the cause and state of the abnormality of the system transmitted from the control unit on the semiconductor light emitting device (LED) and informs, and the user can actively manage the distribution panel by checking it in real time.

It can be connected by using medium speed (9600bps) PLC communication and use a short-range wireless communication chip to check the remote control. At this time, it is preferable to filter the carrier below 40 dB (reference value) using a B / F (Blocking Filter) 170 to prevent the carrier from passing to the neighboring house when using power line communication.

On the other hand, when located outside the distribution panel, the remote control 40 can check and manage the communication status, real-time power amount display (voltage, current, leakage current, temperature), the door open / locked state, remote control By directly showing how much power is currently used in our house through the liquid crystal, we can raise the awareness of the power consumption and have the effect of practicing the power check by ourselves. In addition, there is a door opening and closing function, and if there is a door open outside the set time, the alarm for this also has a security effect.

In addition, by installing the telephone modem 152 in the distribution panel, if the measured room temperature exceeds the reference value or when the door is opened at the set time according to the door lock and opening confirmation function when going to bed for security, the user is notified of an abnormal condition. Emergency calls can be made, and in addition to distribution board management, you can also enjoy security effects.
