Description

一种网关侧电力线通信PLC子***、网关及耦合解耦器Gateway side power line communication PLC subsystem, gateway and coupling decoupler 技术领域Technical field
本发明涉及电通信技术领域，特别涉及一种网关侧电力线通信(Power Line Communication，PLC)子***、网关及耦合解耦器。The present invention relates to the field of electrical communication technologies, and in particular, to a gateway side power line communication (PLC) subsystem, a gateway, and a coupling decoupler.
背景技术Background technique
PLC技术是利用电力线作为传输媒介进行数据传输的一种通信技术，任意一个电源接口通过PLC调制解调器都可以转化为一个网口。PLC technology is a communication technology that uses power lines as a transmission medium for data transmission. Any power interface can be converted into a network port through a PLC modem.
一种PLC***组网如图1所示，包括网关侧PLC子***和终端侧PLC子***，网关侧PLC子***包括传统网关和PLC调制解调器，终端侧PLC子***包括终端和PLC调制解调器。终端向传统网关传输数据时，终端侧PLC调制解调器对终端输入的待传输数据进行调制得到高频信号，将该高频信号耦合于电力线传输的电源信号上，利用该电力线传输该高频信号；网关侧PLC调制解调器通过该电力线接收到该高频信号和该电源信号的耦合信号后，解耦出该高频信号，并对该高频信号进行解调得到待传输数据输出至传统网关，即实现了终端向传统网关传输数据；同理，也可以实现传统网关向终端传输数据。A PLC system networking is shown in Figure 1. It includes a gateway-side PLC subsystem and a terminal-side PLC subsystem. The gateway-side PLC subsystem includes a legacy gateway and a PLC modem. The terminal-side PLC subsystem includes a terminal and a PLC modem. When the terminal transmits data to the traditional gateway, the terminal side PLC modem modulates the data to be transmitted input by the terminal to obtain a high frequency signal, and couples the high frequency signal to the power signal transmitted by the power line, and transmits the high frequency signal by using the power line; After receiving the coupled signal of the high frequency signal and the power signal through the power line, the side PLC modem decouples the high frequency signal, and demodulates the high frequency signal to obtain output data to be transmitted to the traditional gateway, that is, The terminal transmits data to the traditional gateway; similarly, the traditional gateway can also transmit data to the terminal.
由于网关侧PLC调制解调器需要占用一个电源接口，传统网关供电也需要占用一个电源接口，为了节省电源接口，减小布线复杂度，现有技术中，通常会把传统网关和网关侧PLC调制解调器集成于一个设备中，如图2所示，然而，这样必然会使得传统网关和网关侧PLC调制解调器的集成设备的功耗较大、温度较高，从而导致设备可靠性较低。Since the gateway side PLC modem needs to occupy a power interface, the traditional gateway power supply also needs to occupy a power interface. In order to save the power interface and reduce the wiring complexity, in the prior art, the traditional gateway and the gateway side PLC modem are usually integrated into one. In the device, as shown in FIG. 2, however, this inevitably causes the integrated device of the traditional gateway and the gateway side PLC modem to have higher power consumption and higher temperature, resulting in lower device reliability.
