With the national government successively issuing documents on the intelligent construction of coal mines, the construction of smart mines is imminent.
With the national government successively issuing documents on the intelligent construction of coal mines, the construction of smart mines is imminent. Monitoring and monitoring, personnel positioning, pressure wind self-rescue, water supply rescue, communication, emergency avoidance of six systems, these are like the pulse of life, beating the
heartbeat of underground safety. Behind these six systems, more and more products and systems are integrated, and the requirements for downhole data transmission systems are getting higher and higher. In response to the integration reform of the six systems, Ymay Group and customers jointly launched the construction and upgrading project of the underground ten gigabit ring network, which carried out the network transmission upgrade on the basis of the original gigabit ring network and laid a good foundation for the integration and upgrading of the six systems.
In view of the construction goals and needs of coal mines, from the perspective of system safety and stability, Maiwei Communication draws on its rich experience in information construction and operation and maintenance, and creates a set of coal mine 10000 ring network communication solutions for customers, which fully covers the surface and
underground communication needs of coal mines.
System characteristics① The system adopts 10-gigabit optical fiber transmission, and the larger bandwidth carries the larger data amount;
② The Ring network protocol adopts the MWE-Ring V2 protocol ring network, which has more advanced algorithm, more stable network and shorter convergence time (≤20ms);
(3) According to the requirements of special industries, the downhole ten Gigabit ring network switch and expansion switch are optimized for power consumption, heat control and
starting current to meet the requirements of flameproof and coal safety;
④ For the switch management in the network, the MaxView network management has the functions of one-machine deployment, multi-machine access, rapid generation of network topology, historical alarm query, other manufacturers' switch integration management, etc., which truly realizes the unity of the network communication system in the mine and the integration management system.
Construction content
In this scheme, two Layer 3 network management ten Gigabit switches are configured in the ground information room as the core switches of the entire ring network. Install a Ten Gigabit ring network switch in the ground ventilation room and the main shaft room respectively, and form a ten Gigabit Ethernet network through the ten Gigabit optical port and the ten Gigabit optical port of the core switch. In the underground substation, we installed three underground ring network switches to form the downhole 10G Ethernet network through the 10G port and the surface core switch, and the underground 10G ring network switch is expanded through
the gigabit optical port cascade Gigabit switch.
Ten Gigabit industrial Ethernet ring topology
Among them, the ten gigabit ring network switch has the same configuration and different power supply versions in the well. The model of the ten Gigabit ring network switch in the well is MISCOM8028G-4XGF-8GC-16GT-2AD220. The model of the underground ten Gigabit ring network switch is MISCOM8028G-4XGF-8GC-16GT-2DC48. According to the requirements of special industries, the power supply and power consumption are optimized to meet the requirements of coal safety and flameproof. Downhole switch installations are designed to match the customer's flameproof box design, and we also offer extension switches (Model: MES7110-3GF-4F-2D485-2CAN) to
meet more customer needs.
It is understood that compared with the previous use of the system transmission switch, the mining ten gigabit ring network can not only meet the underground a large number of monitoring point data, high-definition video surveillance data access and transmission, but also through the mobile intelligent terminal, the real-time data of the underground system to the relevant responsible units, laying a solid foundation for the
construction of intelligent mines.
