Embodiment Construction

[0021] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0022] Such as figure 1 As shown, the embodiment of the present invention includes: abnormal state data flow direction control unit, two-way hybrid VDSL2 long-line access unit, VDSL2 main control unit, switching unit, network data exchange unit, WiFi base station, WiFi antenna, intrinsically safe power supply unit, in

[0023] Abnormal state data flow direction control unit is used to realize the function of automatic fault removal of the machine. When performing multi-level cascade connection of twisted pair, it can automatically disconnect the connection of the current level when the machine fails or is powered off. The effective connection of the latter stage ensures the normal data exchange of the entire network system;

[0024] The two-way hybrid VDSL2 long-line access unit is two independent VDSL2 access ports that can be connected to the CO or ...

Abstract

The invention relates to a base station, especially a long-line WiFi base station based on VDSL2 technology and multi-level cascading technology, including an abnormal state data flow direction control unit, a two-way hybrid VDSL2 long-line access unit, a VDSL2 main control unit, a switching unit, and a network Data exchange unit, WiFi base station, WiFi antenna, intrinsically safe power supply unit. Realized the seamless integration of Ethernet, WiFi, and VDSL2 long-line access technologies, and created a new long-line network access mode. It has the advantages of long transmission distance, intrinsic safety, high bandwidth, saving wiring, and easy management. It can be widely used in the fields of ground and mine data communication.

Description

technical field [0001] The invention relates to a base station and multi-stage cascading technology, in particular to a long-line WiFi base station and multi-stage cascading technology based on VDSL2 technology. Background technique [0002] With the development of communication technology and economy, more and more network devices are used underground in coal mines, and most mines have their own underground Gigabit Ethernet ring network, which promotes the development of wireless broadband WiFi base stations in underground mines. The coverage of each base station exceeds 200m, but the traditional Ethernet electrical signal cable can only transmit up to 100m, so the WiFi base station is required to be close to the downhole switch, which limits the scope and quantity of WiFi base stations. Then if you choose optical signal, although the optical signal can transmit a long distance, it is difficult to move the optical cable, the mobility of the optical fiber equipment is poor, ...
