Ring network system for middle sections of underground mines and method for constructing ring network system

Abstract

The invention discloses a ring network system for middle sections of underground mines and a method for constructing the ring network system. The ring network system comprises a first type base station network switch installed on the ground and a plurality of second type base station network switches respectively installed in the middle sections of the underground mines, wherein the plurality of second type base station network switches are respectively connected in series to the first type base station network switch through communication connection lines to form the ring network on the ground. Therefore, regardless of the occurrence of a disconnection at any point in the ring network system, that all the switches in the entire ring network are still connected is ensured, a substantial ring network structure is achieved, and the reliability and security of the ring network are ensured.

Description

Technical field [0001] The invention relates to the field of comprehensive network communication for mines, in particular to a ring network system used in the middle section of an underground mine and a method for constructing the ring network system. Background technique [0002] At present, the method of constructing a ring network in the same middle section of an underground mine is usually realized by means of jumpers, that is to say, using jumpers to connect switches to construct a mining industrial ring network system. For example, jumper switches in a certain direction in the same lane, and when the switch is at the end, return to jumper switches that are not wired, and finally connect to the first switch to form a ring network. For example, such as figure 1 As shown, there are 1#~5# switches in the order of physical location in the same middle section of the roadway, 1# switch is connected to 3#, 3# is connected to 5#, and 5# switch is returned to 4# switch , And then co...

Problems solved by technology

[0003] However, the current problem is that although a ring network in the same middle section is formed in the topological structure, in actual construction, the ring is formed in the same roadway. For example, at point A, both K1 optical cable and K2 optical cable pass through point A. , at point A, the two optical fibers are in the same roadway or even in the same cable, once an accident occurs at point A and cuts off the roadway or the optical cable, two bad points will go out in the ring network system at the same time, at this time 1#~3# No. switch is disconnected from No. 4# and No. 5# switches, causing the ring network system to become a "false ring network", which cannot give full play to the security of the ring network, and also reduces the reliability of the ring network
