Mining safety monitoring

The coal mining safety monitoring system applies computer technology, sensor technology, communication technology and control technology to coal mine production, and ensures safe production by monitoring the underground environment and equipment. With the digital upgrade of sensors and equipment, Zhiyuan Electronics can provide users with highly reliable RS-485 isolation communication and other solutions.

RS-485 isolated communication

The wired sensor uploads the data to the monitoring substation through RS-485 bus, and the monitoring substation uploads the data to the monitoring platform through Ethernet so as to monitor the internal environment of the mine in real time.

Features of Isolated RS-485 transceiver

  • Up to 110 nodes;
  • High isolation voltage, up to 5000VDC;
  • Ultra-wide temperature range, operating temperature -40℃~+105℃;
  • Level 3 surge protect with SP00S12.
