Mobile communication network relay device

Abstract

The invention provides a mobile communication network relay device, including a near-end unit and a remote unit; the near-end unit includes: a first main controller, a first local maintenance interface, an Ethernet transmission module, and a first high-speed data transmission module. The radio and the first power module, the first local maintenance interface, the Ethernet transmission module and the first high-speed data transmission radio are all connected to the first main controller, the near-end unit is connected to the concentrator through the Ethernet transmission module, and the near-end unit is connected to the concentrator through the The first local maintenance interface is connected to an external user terminal, and the first power supply module supplies power for the first main controller, the first local maintenance interface, the Ethernet transmission module and the first high-speed data transmission radio. The beneficial effect of the invention is that the signal transmission distance between the Ethernet transmission device and the concentrator is extended by enhancing the signal.

Description

technical field [0001] The present invention relates to a communication device, in particular to a mobile communication network relay device. Background technique [0002] Signal relay device, specifically refers to a device used to relay and transmit mobile communication network signals through wired channels and other wireless channel resources in the signal blind area or signal instability area of ​​the mobile communication network, so that the devices in the area can communicate using the mobile communication network normally. A relay device belongs to the field of electric power operation and maintenance on-site detection. With the rapid development and application of smart grid technology in China, the electricity consumption information collection system for power users is becoming more and more mature, but its terminal equipment is installed in various complex environments, and there are 2G, 3G or 4G signals in some areas that are not covered or signal. In the unsta...

Problems solved by technology

Although this device has realized the normal communication function of the concentrator in the signal blind area of ​​the mobile communication network, the shortcoming that this device still exists is: 1) for the general first RJ45 Ethernet data access unit and, it is only used for Short-distance signal transmission, if the signal is far away, the quality of the signal it transmits is just poor, so it cannot be used for long-distance transmission signal; 2) when the chip of the first RJ45 Ethernet data access unit is in use, its chip The terminal is not isolated from the outside, so in the process of transmitting or receiving signals, the transmitted signal will be interfered, so the chip will be damaged due to lightning strikes and other reasons
