Abstract: In order to solve the problems of poor stability, low data reliability, weak intelligence and complicated operation and maintenance of the existing safety monitoring system of the coal mine, Shendong Coal Group took the lead in upgrading the safety monitoring system, and then the KJ83X(A) safety monitoring. The system was successfully upgraded and upgraded in Daliuta Coal Mine. The system uses CAN bus mode to transmit data through the mine “four-in-one” network, realizing full digital transmission, long-distance power supply, grading alarm, logic alarm, emergency intelligent linkage, and more. System integration and other functions, to prevent data transmission interruptions and false alarms, improve the efficiency and accuracy of uploading data, effectively improve mine accident warning and emergency response capabilities, and ensure the safe production of mines.
