Mine safety monitoring and control plays an extremely important role in coal mine safety production, productivity improvement and equipment utilization. Mine modern safety monitoring and monitoring system mainly includes gas drainage (discharge) monitoring system, rail transportation monitoring system, belt transportation monitoring system, power supply monitoring system, drainage monitoring system, fire monitoring system, mine pressure monitoring system, coal and gas outburst monitoring, Personnel location monitoring system, etc. In terms of transmission, the ground and underground subsystems are connected through a mature and reliable Ethernet optical fiber redundant ring network.

 

A series of low-power industrial Ethernet switch systems for mines have been specially developed for mine safety monitoring and monitoring systems. The backbone optical fiber Ethernet network in the mine uses Mwring fast ring network technology for redundancy, ensuring that the safety monitoring and monitoring network can also be normal when the optical cable fails. run. MIEN5108 is used in the underground to form a 100M optical fiber redundant ring network, and the ring-to-ring coupling method is used to connect the ground and underground ring networks together.

 

Low-power switches can provide Ethernet optical ports or electrical ports for video surveillance systems, personnel positioning systems, etc. in underground branches, and converge video data or positioning information to the core ring network in a cascaded manner. The core module switch can meet the flexible configuration of the optical port of the interface in application, and meet the needs of embedded applications. The Ethernet switch provides RS-485 bus interface and CAN bus interface, which provides strong guarantee for customers in the highly integrated application of Ethernet transmission.
