Mine safety monitoring and control plays an extremely important role in coal mine safety production, improving productivity and equipment utilization rate. Mine modern safety monitoring and monitoring system mainly includes gas extraction (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 position monitoring system, etc. In the transmission, the ground and underground subsystems are connected through a mature and reliable Ethernet fiber redundant ring network.
MAIWE has specially developed a series of low-power industrial Ethernet switch systems for mining safety monitoring and monitoring systems. The backbone Ethernet network uses MW-ring fast ring network technology for redundancy, ensuring the safety monitoring and monitoring network when the optical cable fails. It can also run normally. MIEN5108 is used to form a 100M fiber redundant ring network underground, and the ground and underground ring network are connected together by coupling between rings.MIEN2105A low-power switch can provide Ethernet fiber ports or copper ports for video surveillance systems, personnel positioning systems, etc. in the underground branch, and cascade the video data or positioning information to the core ring network. The core module switch can meet the flexible configuration of the fiber and copper interface for various applications and the needs of embedded applications. MIGE7110 and MIEN5108 Ethernet switches provide RS-485 bus interface and CAN bus interface, which provides a strong guarantee for customers' highly integrated applications in Ethernet transmission.
