Broadband power local side network bridge

Abstract

The invention relates to the technical field of network transmission devices, in particular to a broadband power local side network bridge. The broadband power local side network bridge is easy to maintain, stable in signal and high in adaptability. The broadband power local side network bridge comprises a box body, a working cavity is formed inside the box body, a power module and a main board are arranged in the working cavity of the box body, and external network equipment interfaces, a plurality of PLC carrier wave modules, upper PCI slots, lower PCI slots and coupling signal interfaces are arranged on the main board. The power module is electrically connected with the external network equipment interfaces, the PLC carrier wave modules, the upper PCI slots, the lower PCI slots and the coupling signal interfaces. The input ends of the external network equipment interfaces are electrically connected with external network equipment, the output ends of the external network equipment interfaces are electrically connected with the upper PCI slots, the output ends of the upper PCI slots are electrically connected with the PLC carrier wave modules, the output ends of the PLC carrier wave modules are electrically connected with the lower PCI slots, and the output ends of the lower PCI slots are electrically connected with the coupling signal interfaces.

Description

technical field [0001] The invention relates to the technical field of network transmission devices, in particular to a broadband power local end network bridge. Background technique [0002] As we all know, the local end power network bridge is a power line communication technology, referred to as PLC technology. Mode, high transmission quality, fast speed, stable bandwidth and other remarkable features, it is widely used in residential areas, hotels, office areas, monitoring security and other fields, especially for broadband reconstruction of existing buildings, PLC bridge is used in power line communication It is a network access device for small and medium-sized local area networks. One end of it is connected to the external Ethernet, and the other end bridges the Ethernet information to the user's power grid through a signal coupling line. Each PLC bridge can carry multiple PLC local ends (modems); but now In the use of some local power network bridges, it is found th...

[0002] As we all know, the local end power network bridge is a power line communication technology, referred to as PLC technology. Mode, high transmission quality, fast speed, stable bandwidth and other remarkable features, it is widely used in residential areas, hotels, office areas, monitoring security and other fields, especially for broadband reconstruction of existing buildings, PLC bridge is used in power line communication It is a network access device for small and medium-sized local area networks. One end of it is connected to the external Ethernet, and the other end bridges the Ethernet information to the user's power grid through a signal coupling line. Each PLC bridge can carry multiple PLC local ends (modems); but now In the use of some local power network bridges, it is found that its transmission speed is low, the signal is unstable, there are noises, maintenance and upgrade are complicated, and the power supply location is controversial.
