Looped network router used in wireless MESH network

Abstract

The invention discloses a looped network router used in a wireless MESH network. The looped network router comprises a core processing module, a WIFI module, an Ethernet data exchange module, an SD card slot, a DDR2 memorizer module, a flash memory module, a USB module, a 25MHz crystal oscillator and a power supply module; wherein the core processing module is respectively in double-way connection with the Ethernet data exchange module and the 25MHz crystal oscillator; the WIFI module is respectively in double-way connection with the SD card slot, the DDR2 memorizer module, the flash memory module and the USB module; each kilomega serial port of the core processing module is connected with a kilomega optical fiber communication port so as to add access ways of the router; the WIFI module detects and accesses in a wireless network of other neighbouring router so as to provide wireless connection for the user; the core processing module and the WIFI module are interconnected via an MII port. The looped network router used in the wireless MESH network of the invention can be used for forming an optical fiber loop network, an electric loop network and a photoelectric loop network, and the looped network manner is flexible. The looped network router used in the wireless MESH network of the invention could remove the dead space of the network and solve the problem that the wiring is difficult.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a ring network router, which can be used in a wireless MESH network. Background technique [0002] Wireless MESH network is a new type of multi-hop wireless network with no center self-organization. This kind of network has high flexibility, reliability, and supports expansion, so it has a good application prospect. In this kind of network, the backbone network routers can be connected into a ring network. Each router provides WIFI connection to users in its coverage area. User nodes choose the most suitable wireless network access according to their location. Information transmission in the network adopts multi-hop The way. [0003] Wireless MESH networks require routers to be able to connect to form a ring network. The existing routers have a single network interface and the ring network mode is not flexible. For example, the Chinese patent application number...
