Mine safety monitoring

Coal mine safety monitoring system is to apply computer technology, sensor technology, communication technology and control technology to coal mine production and ensure safe production by monitoring the subsurface environment and equipment. With the digital upgrading of sensors and equipment, Zhiyuan Electronics can provide users with highly reliable RS-485 isolated communication and other solutions.

RS-485 isolated communication scheme

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 RS-485 module

  • Domestic guarantee, 100% domestic components;
  • Multiple nodes, up to 256 nodes for connection;
  • High isolation and withstand voltage, up to 5000VDC;
  • Ultra-wide temperature range, operating temperature -40℃~+105℃;
  • High protection, SP00S12, level-3 surge.
