Example two
As shown in fig. 3, a mining 5G bearer network networking method adopts the mining 5G bearer network networking system of the first embodiment. The mining 5G bearer network networking method comprises the following steps:
s1: the PTP clock server 2 sends a time synchronization message to the Ethernet 1, and the Ethernet 1 sends the time synchronization message to the optical fiber direct connection network 3, the mining ten-thousand-million industrial ring network 4 and the F5G optical transmission network 5, so that clocks of all devices in the system can be accurately synchronized.
S2: the underground 5G far-end gathering station 6 sends the received underground information to a 5G miniaturized core network 8 through the light direct-connection network 3, and the 5G miniaturized core network 8 sends the underground information to the Ethernet 1; the underground 5G base station controller 7 sends the received underground information to the Ethernet 1 through the mining ten-million industrial ring network 4; the downhole 5G base station controller 7 sends the received downhole information to the ethernet 1 via the F5G optical transmission network 5.
S3: the ethernet 1 retransmits the received downhole information to the surface control room.
It should be noted that accurate time control is required for switching and roaming of the communication base station, and sufficient stability is also required for high synchronization accuracy. If the time between the communication devices is not synchronized, the time slot and the frame will be affected, and the normal operation of the service will be affected, for example, the uplink and downlink time slot interference is generated, the base station location service based on the time difference of arrival (TDOA) cannot be realized, and the like. Meanwhile, the three networks of the optical fiber direct connection network 3, the mining gigabit industrial ring network 4 and the F5G optical transmission network 5 also need time synchronization, if the time is not synchronized, the network transmission delay is increased, the network transmission rate is reduced, even the access and the switching of equipment are affected, so that information cannot be timely acquired by a ground control room, and the work is affected.
In this embodiment, the ethernet 1, the PTP clock servers 2, 5G miniaturized core network 31, the baseband control unit 32, the ground ring network switch 41, and the F5G optical line terminal 51 are ground devices, and the optical fiber 33, the mining ring network access device 42, the mining optical cable 43, the mining intrinsically safe optical splitter 52, the mining F5G optical network unit 53, and the mining intrinsically safe F5G optical network unit 54 are downhole devices.
In this embodiment, the downhole 5G base station controller 7 includes a convergence station and a downhole base band control unit. In the optical fiber direct connection network 3, the baseband control unit 31 is a ground device, and because the optical fiber direct connection network 3 is suitable for connecting devices which are close to the ground in a downhole manner, the baseband control unit 31 does not have a delay problem when being placed on the ground. The mining ten-thousand-million industrial ring network 4 and the F5G optical transmission network 5 are suitable for positions far away from the ground under a mine, so that the underground 5G base station controller 7 integrates the convergence station with the underground base band control unit, the underground base band control unit can process data transmitted by the 5G base station nearby, the delay problem is reduced, and the data error is reduced.
In summary, the mining 5G bearer network networking system of the present invention can be applied to a special roadway environment in a coal mine, for example, the roadway has a long total length, many branches, flammable, explosive and corrosive gases, and the like, and can meet the requirements of a mine communication system on a large throughput (up to 20Gbps), a low time delay (the time delay can be within 10 ms), and high transmission reliability of the bearer network. One bearing network is provided with various transmission networks, so that the selectivity is high, the adaptability is good, and the diversified environment of the underground coal mine can be met.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention.
