Abstract: According to the policies on the manufacturing of national energy equipment, coal mine robots and intelligent development of coal mines as well as the trend of intelligent development of coal equipment, a remote monitoring system of automatic drilling rigs for coal mines is developed to monitor the automatic drilling rig remotely on the ground by using sensor measurement, software development, virtual reality, network communication, video monitoring and other technologies. The problems of incomplete parameter display, insufficient effective monitoring and inconvenient maintenance of the existing underground coal mine drilling rig are solved. The remote monitoring system includes the main rig, onboard equipment, network communication part and remote monitoring server. The main body of the drill is the ZDY4500LFK coal mine drill. The onboard equipment includes controllers and sensor arrays for rig parameter acquisition. The network communication part includes switches, gateways, etc. to realize communication between the underground and surface. The remote monitoring server realizes the monitoring of rig parameters and working conditions. The system was tested in Tangjiahui Coal Mine of Huaxing Energy Co. LTD in Ordos. The results show that the system has accurate data transmission, by which the ground monitoring function of automatic drilling rig is realized. It provides a guarantee for the intelligent development of coal mine drilling rigs.
