Embodiment Construction
[0018] figure 1 It is a schematic structural diagram of the power access network system in the embodiment of the present invention. The access network system is mainly based on power line access, which is mainly connected to the power line with the function of transmitting signals through network equipment. The network equipment only Through the access of a power line, the power signal and network signal are received, the network signal is separated, and sent to the modem module for modulation and demodulation processing, thus realizing the communication between the network device body and the power line communication purposes. At the same time, the network device also receives the network signal in the network device body, and multiplexes the network signal on the power line for transmission, thereby realizing information exchange between various network devices. The power supply module in the network equipment body can not only realize the separation and multiplexing of net...

The embodiments of the invention disclose a communication method based on power line access. The method comprises: receiving power signals and network signals through the power module in a network device body; and separating the network signals, and sending the separated network signals to a modem module for modem processing. The embodiments of the invention also disclose a network device. The network device comprises a power module and a modem module, wherein the power module is used for receiving power signals and network signals, separating the network signals and sending the separated signals to the model module; and the modem module is used for performing modem processing on the network signals separated by the power module such that the communication between network device bodies based on electric line devices is realized. By implementing the method and the network device provided by the invention, the network convenience, security and reliability of users are improved.
Description
technical field [0001] The invention relates to the technical field of power line communication, in particular to a power line communication method and network equipment. Background technique [0002] With the rapid development of broadband network technology, it has begun to play a huge role in people's work and life. Online distance education, online publishing, printing, online communication, and online TV have shrunk the world and shortened time and distance. [0003] At present, a new broadband access technology, that is, power line access, is emerging. Power line communication (PLC, Power Line Communication) refers to a communication method that uses power lines to transmit high-frequency data and voice signals. The modem of power line communication is referred to as "power cat" for short. One end of it is plugged into the user's computer, and the other end is plugged into any power outlet in the home to achieve a transmission rate of up to 14Mbps or 45Mbps, thereby r...
