Description

Standby power individual control device of power line communication control system {APPARATUS FOR INDIVIDUAL CONTROLLING STANDBY POWER OF POWER LINE COMMUNICATION CONTROL SYSTEM}

The present invention relates to a standby power individual control device of the power line communication control system, and in detail, the power supplied to each office, such as public buildings, buildings, building factories, etc. within each office or wireless control or in the inter-layer controller The present invention relates to a stand-by power control device of a power line communication control system that prevents unnecessary standby power and makes it convenient to use a load device by easily and easily blocking and restoring standby power to a load in each office by wireless control.

In general, public buildings, buildings, and factory-type factories are installed in the distribution boxes of each floor in the building, that is, each office wiring or distribution box through a distribution box composed of a main switch, an earth leakage breaker that prevents fire from overload or short circuit. It will be supplied to a number of outlets embedded in the floor.

At this time, the power supplied to each office wiring or a plurality of outlets buried in the floor is constructed by using each power line, the number of power lines has a problem that the wiring work and construction is cumbersome and complicated.

In addition, most of the power used in each office where power lines are constructed is managed by a central management system installed in the building. In this case, a separate cable is constructed between the central management system and each office for management. As it is managed, the wiring in buildings has become more complicated.

At this time, the central management system that manages the power of each office manages the power used by each office, but does not manage the standby power generated by various load devices that are not used while plugged into the outlets in each office. I can't do it.

In other words, when the various load devices connected to the outlet are not used while being plugged into the outlet, power is charged from the outlet and the standby power is always generated, causing unnecessary power loss.

Therefore, each office has to pull out the power cord of the load device from the outlet when not using various load devices, but it is prudent to pull out all the power cords from the outlet when not actually using or when going out or going to work. If you do not pay attention to the situation is still difficult to waste unnecessary power.

Recently, in order to control the standby power, Patent Application No. 2008-0110208 (name: outlet having a standby power / constant power selection function and standby power control device using the outlet), the commercial AC power is applied At least one connection port consisting of a first terminal and a second terminal is provided with a receptacle installed in the wall of the room, and the standby power line and the regular power line is connected to the outlet separately, the standby according to the user's operation The selection switch and standby power line that selects the power line or the continuous power line to supply standby power or the continuous power to the connection port and the standby power control device that can cut off the standby power supplied to the outlet 1 by the user's operation. There is a thing to cut off the standby power when the load side is all off.

Further, according to Patent Application No. 2008-0089329 (name: standby power control system, standby power control device, and standby power control method), connected to the electronic device to measure the power consumption of the electronic device, A power line communication agent unit for connecting or disconnecting the supplied power; A Zigbee sensor unit for sensing environmental information and situation awareness information; And considering information provided from the Zigbee sensor unit, power consumption information of the electronic device provided from the power line communication agent unit, a standby power control mode (going out mode, home mode) and a power line communication agent unit that are currently locked and opened. There is a standby power control device for controlling the power line communication agent unit so that the power supplied to the electronic device is connected or disconnected to control the standby power to the electronic device on the load side.

However, in the case of the former, there is a difficult problem in complicated wiring and construction, in which a separate standby power line and a selection switch for selecting the standby power line must be provided at outlets connected to various devices, and the user selects them individually. It is troublesome to select the constant power or standby power by operating the switch, and the standby power control device also cuts the standby power according to the user's selection operation, so the user must always pay close attention to cut off the standby power. There is a troublesome problem.

In the latter case, a standby power control device for controlling standby power is provided with a Zigbee sensor and a power line communication agent unit in each electronic device, and the Zigbee sensor and a power line communication agent unit are configured by setting a standby power mode of the standby power control device. It is designed to control the standby power by detecting the surrounding devices and load devices, but does it still have the complexity of setting the standby power control device to standby power mode and controlling the power line communication agent unit to cut off standby power of the load device? In order to control the standby power, there is a problem in that a complicated configuration and wiring of the entire system, which must be provided with a Zigbee sensor and a power line communication agent for each load device, respectively.

As described above, the conventional standby power cut-off device selectively blocks standby power by the user, or detects and cuts off the load at the agent unit by setting the mode, so that if the user acts in a hurry, the standby power may not be blocked. If you do not have the problem often occurs.

An object of the present invention is to prevent unnecessary standby power consumption by shutting off the standby power to the load device in the office by individual wireless control in the office or through the floor controller when leaving the load device connected to the outlet of each office and going out for a long time There is.
