KJ785 impact ground pressure monitoring system

The impact ground pressure monitoring system is a monitoring system developed by our company based on the development needs of coal mines to monitor the dynamic change trend of tunnel top pressure and transmit current separation layer data in real time. This system solves the problem that current top-board monitors cannot achieve real-time transmission, and the system uses bus transmission mode to enable multiple substations and multiple extensions to work simultaneously. The on-hole monitoring software can save monitoring extension data in real time, form reports and draw curves, and perform software analysis on roof displacement changes, allowing staff to grasp the dynamic changes in roof displacement in a timely manner and make timely predictions and processing
