Real-time monitoring and timely warning of illegal intrusion of drilling rigs above the subway line are significant for subway safety management. Distributed optical fiber sensing technology is an effective measure to meet the needs of long-distance, remote real-time monitoring. To detect and locate the illegal intrusion of drilling rigs above the subway line in time, the ultra-weak fiber optic Bragg grating sensing array is used to collect the distributed vibration response caused by the drilling rig intrusion incident. Based on the vibration signal characteristics of the engine of the drilling rig, a method to identify and locate the illegal intrusion of the drilling rig in real time including drilling rig engine identification and effective information statistical analysis is proposed. The purpose of effective information statistical is to improve the anti-noise ability of identification. Field test results show that the method can resist ground and underground traffic load interference, and achieves recognition deviation within 10m to identify and locate simulated drilling rig intrusion scenarios.
