본 발명은 정보전달을 위한 통신이 요구될 경우에만 전기에너지를 전력선통신장치에 공급하여 전력선통신장치가 동작하도록 하고, 통신이 요구되지 않거나 통신을 하지 않을 경우에는 전력선통신장치에 전기에너지 공급을 중단하여 절전이 가능하도록 하며, 또한 전기에너지 공급이 중단된 시기인 턴오프 상태에서도 전력선통신장치에 통신요구가 요청될 경우 다시 턴온되는 동작을 동시에 수행하도록 한 절전형 양방향 전력선 통신장치에 관한 것이다.According to the present invention, the power line communication device operates by supplying electrical energy to the power line communication device only when communication for information transmission is required, and stops supplying electric energy to the power line communication device when communication is not required or communication is not required. The present invention relates to a power-saving two-way power line communication device that performs power-saving operation and simultaneously turns on again when a communication request is requested to a power line communication device even in a turn-off state when electric energy supply is stopped.
최근 홈네트워크 구성과 관련하여 홈네트워크 연결가능한 정보통신 제품들이 많이 출시되고 있는 가운데, 이 제품들이 홈네트워크 연결을 위한 수단으로서 주로 유선통신네트워크와 무선통신네트워크 기술을 활용하고 있다. Recently, a lot of information communication products capable of connecting to home networks have been released in connection with the construction of home networks, and these products mainly use wired communication networks and wireless communication network technologies as a means for connecting home networks.
일반적으로 전력선통신은 전기선을 통해 통신이 구현되는 기술이며, 전력선 통신기반의 정보통신 제품은 반드시 전력선통신장치가 내장 또는 외장 형태로 제품과 연결되어 있다. 정보통신제품은 정보전달을 위해 주요한 기능이 통신이며, 통신을 위해 상시적으로 동작가능한 상태를 유지하고 있어야 하며, 그 유지를 위해서 전력선통신장치가 턴온상태로 유지되도록 전기에너지를 계속 공급하여야 한다.In general, power line communication is a technology in which communication is implemented through an electric line, and an information communication product based on power line communication is necessarily connected to the product in a form of an internal or external power line communication device. Telecommunications products must have a main function for communication, and maintain a state of constant operation for communication, and to maintain electric power to keep the power line communication device turned on.
따라서, 종래에는 정보통신을 위해서 통신상태이거나 아니거나 관계없이 전력선통신장치에 항상 전기에너지를 공급하므로 불필요한 전력이 소모되는 문제점이 있었는바 도 1을 참조하여 개략적으로 설명한다.Therefore, in the related art, since the electric energy is always supplied to the power line communication apparatus regardless of whether the communication is in a communication state or not, there is a problem in that unnecessary power is consumed.
도 1에는 종래의 전력선통신장치의 일반적 회로구성이 도시되어 있는바, AC전원에서 DC전원으로의 변환을 하는 전원부와 전력선통신을 위한 전력선통신모뎀과 주변회로로 구성되어 있다. FIG. 1 shows a general circuit configuration of a conventional power line communication device, and includes a power supply unit for converting AC power to DC power, a power line communication modem for power line communication, and a peripheral circuit.
종래의 전력선통신장치의 경우 동작순서 및 원리는 도 1에서와 같이 전기선 또는 전력선(이하 전력선 표기)으로부터 AC전원을 공급받아서 일정회로를 통해 DC저압전원으로 변환하고, 이 DC전압을 전력선통신모뎀에 제공함으로서 전력선통신모뎀이 동작이 가능하며, 이 때의 전력선통신모뎀동작에 의해서 전력선에서부터 전송되어 오는 정보데이터를 전력선통신모뎀에서 수신받고, 해당명령(Dmd, Command)을 수행하거나, 해당명령에 대한 응답정보(Information)을 전력선으로 다시 송신하도록 구성되어 있다. 따라서, 도 1에 도시된 종래의 전력선통신장치는 통신을 할 경우에는 물론 통신이 요구되지 않거나 통신을 하지 않을 경우에도 항상 통신을 위해 턴온상태를 유지하여야 하므로 불필요한 전력이 소모되는 문제점이 있었다.In the case of the conventional power line communication device, the operation sequence and principle are as shown in FIG. 1, and the AC power is supplied from an electric line or a power line (hereinafter referred to as power line) to convert to a DC low voltage power supply through a predetermined circuit, and the DC voltage is converted into a power line communication modem. By providing the power line communication modem can be operated, by receiving the information data transmitted from the power line by the power line communication modem operation at the power line communication modem, and performs a corresponding command (Dmd, Command), or And transmit the response information back to the power line. Therefore, the conventional power line communication apparatus shown in FIG. 1 has a problem in that unnecessary power is consumed because communication must be always turned on for communication even when communication is not required or communication is not required.
본 발명은 상기와 같은 문제점을 해소하기 위해 창출된 것으로서, 본 발명의 목적은 정보전달을 위한 통신이 요구될 경우에만 전기에너지를 전력선통신장치에 공급하여 전력선통신장치가 동작하도록 하고, 통신이 요구되지 않거나 통신을 하지 않을 경우에는 전력선통신장치에 전기에너지 공급을 중단하여 절전이 가능하도록 하며, 전기에너지 공급이 중단된 시기인 턴오프 상태에서도 전력선통신장치에 통신요구가 요청될 경우 다시 턴온되는 동작을 동시에 수행하도록 한 절전형 양방향 전력선통신장치를 제공함에 있다. The present invention has been made to solve the above problems, and an object of the present invention is to supply electric energy to a power line communication device only when communication for information transmission is required so that the power line communication device operates, and communication is required. If it does not communicate or does not communicate, the power line communication device stops supplying electric energy to enable power saving. When the communication request is requested to the power line communication device even when it is turned off, the operation is turned on again. It is to provide a power-saving bidirectional power line communication device to perform simultaneously.
상기와 같은 목적을 달성하기 위한 본 발명에 따른 절전형 양방향 전력선통신장치는, AC전원을 DC전원으로 변환하는 전원부와; 전력선통신이 가능한 전력선통신모뎀과; 전력선통신모뎀의 통신데이터의 해석 및 대응처리를 수행하는 소형 마이크로컨트롤러와; 전력선통신을 감지할 수 있는 센서; 및 상기 전원부와 전력선통신모뎀사이에 통전 및 차단용 스위치로 구성됨을 특징으로 한다.According to an aspect of the present invention, there is provided a power saving type bidirectional power line communication apparatus including: a power supply unit for converting AC power into DC power; A power line communication modem capable of power line communication; A small microcontroller for analyzing and corresponding processing of communication data of the power line communication modem; A sensor capable of sensing power line communication; And a switch for energizing and cutting off between the power supply unit and the power line communication modem.
본 발명에 이용되는 센서는 전력선으로부터 전력선통신데이터가 수신되고 있는지 감지기능을 갖는 것이 바람직하고, 소형 마이크로컨트롤러는 센서의 신호에 따라서 스위치를 제어하여 전원부와 전력선통신모뎀간의 DC전원공급선을 온/오프시키도록 하는 것이 바람직하다.Preferably, the sensor used in the present invention has a function of detecting whether power line communication data is being received from the power line, and the small microcontroller controls the switch according to the signal of the sensor to turn on / off the DC power supply line between the power supply unit and the power line communication modem. It is desirable to make it.
이하 본 발명의 실시예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은, 임의의 짧은 시간동안에 발생할 통신을 위해서, 통신상태이거나 아니거나 상기 언급한 전력선통신장치에 항상 전기에너지를 공급하는 기존방식에서, 정보전달을 위한 통신이 요구될 경우에만 전기에너지를 전력선통신장치에 공급하여 전력선통신장치가 동작하도록 하고, 통신이 요구되지 않거나 통신을 하지 않을 경우에는 전력선통신장치에 전기에너지 공급을 중단하여 절전이 가능하도록 한 장치이다. The present invention, in the existing scheme of always supplying electrical energy to the above-mentioned power line communication apparatus for the communication to occur during any short time, the electrical energy to the power line only when communication for information transmission is required. The power line communication device operates by supplying the communication device, and when the communication is not required or the communication is not performed, the power line communication device stops supplying electric energy to enable power saving.
또한, 전기에너지 공급이 중단된 시기인 턴오프 상태에서도, 전력선통신장치에 통신요구가 요청될 경우 다시 턴온되는 동작을 동시에 포함한다.In addition, even in the turn-off state when the electric energy supply is stopped, the operation of turning on again when the communication line is requested to the power line communication device is included.
본 발명은 도 1에 도시된 기존의 전력선통신회로에 소형 마이크로컨트롤러와 전력선통신을 감지할 수 있는 센서를 추가한 것을 특징으로 하며, 이러한 추가장치를 이용하여 절전이 가능한 전력선통신장치를 실현한다. The present invention is characterized by the addition of a sensor capable of detecting a small microcontroller and power line communication to the existing power line communication circuit shown in Figure 1, and realizes a power line communication device capable of saving power using such an additional device.
본 발명에 따른 절전형 전력선통신장치를 실현하기 위한 기술적 과제로서는, 도2와 같이 소형 마이크로컨트롤러와 전력선통신을 감지할 수 있는 센서를 추가하고, 전원부와 전력선통신모뎀간의 DC전원공급선을 단속할 수 있도록 전자스위치를 삽입하여 초기상태에서는 전원부에서 전력선통신모뎀에 전원이 공급되지 않도록 DC전원 차단상태를 유지하도록 하였다.As a technical problem for realizing a power-saving power line communication apparatus according to the present invention, a sensor capable of detecting power line communication with a small microcontroller as shown in FIG. 2 is added, and a DC power supply line between the power supply unit and the power line communication modem can be interrupted. In the initial state, the electronic switch was inserted to keep the DC power off so that the power line communication modem was not supplied with power.
이러한 전원단속제어는 마이크로컨트롤러에서 제어할 수 있도록 구성하였으며, 이때 마이크로컨트롤러는 수신센서로부터 신호를 입력받도록 하였으며, 센서는 전력선으로부터 통신요청을 위한 데이터가 수신되고 있는지 감지하는 기능으로서, 전력선통신데이터가 전력선에 실려 수신될 경우 센서는 마이크로컨트롤러에 신호를 발생한다.The power interruption control is configured to be controlled by a microcontroller. At this time, the microcontroller receives a signal from a receiving sensor. The sensor detects whether data for a communication request is being received from the power line. When received on a power line, the sensor generates a signal to the microcontroller.
이상의 구성을 기초로 센서에서 전력선통신 신호가 발생되면 마이크로컨트롤러가 이 신호를 인지하고, 전원부에서 전력선통신모뎀으로 전원공급이 가능하도록 전자스위치를 턴온시켜 전력선통신모뎀이 정상동작이 가능하도록 한다. Based on the above configuration, when the power line communication signal is generated from the sensor, the microcontroller recognizes the signal and turns on the electronic switch to supply power to the power line communication modem from the power supply unit so that the power line communication modem can operate normally.
전력선통신모뎀이 정상동작할 경우, 전력선통신모뎀은 전력선으로부터 오는 통신데이터 또는 수행명령내용을 마이크로컨트롤러에 전달하고, 마이크로컨트롤러는 이러한 내용을 판단하여 해당동작이 이루어지도록 한다. When the power line communication modem operates normally, the power line communication modem transmits the communication data or the execution command from the power line to the microcontroller, and the microcontroller determines the content so that the corresponding operation is performed.
따라서, 통신이 요구되는 시간에만 전력선통신모뎀을 턴온하고, 전력선으로부터 통신완료의 정보가 전송되면, 이러한 명령을 전력선통신모뎀을 통해 마이크로컨트롤러가 해석하고 이를 바탕으로 전자스위치를 턴오프시킴으로서, 통신종료직후 턴오프하는 동작을 수행함으로서 기존 전력선통신장치에 비해 획기적으로 절전할 수 있다.Therefore, when the power line communication modem is turned on only at the time when communication is required, and the communication completion information is transmitted from the power line, the microcontroller interprets the command through the power line communication modem and turns off the electronic switch based on the command. By performing the operation of turning off immediately, it is possible to save power significantly compared to the existing power line communication device.
이상 설명한 바와 같이 본 발명은 사용자에 의해 가전기기가 사용되지 않고 있거나 통신대기상태에 있을 경우 전기소비를 1W와트이하로 낮추는 절전효과를 지닌 매우 유용한 발명이다. As described above, the present invention is a very useful invention having a power saving effect of lowering the electricity consumption to 1W or less when the home appliance is not used by the user or in a communication standby state.
