Title:
NETWORK NEURAL CABLE-BASED MUNICIPAL BURIED CABLE BREAKAGE DETECTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/213608
Kind Code:
A1
Abstract:
A network neural cable-based municipal buried cable breakage detection system and method. The detection system comprises a seismic source generation apparatus and a breakage detection apparatus. The seismic source generation apparatus is used for applying a seismic power to the road surface of a line to be tested. The breakage detection apparatus is connected to a connection device in a municipal cable well, and is used for determining a specific breakage segment of a cable breakage area. The detection method comprises the following steps: determining the cable breakage area (S1); selecting a detection starting point according to the cable breakage area (S2); a cable detection step: performing power-on detection on the detection starting point, and determining a detection route according to the connection condition of a municipal electrical appliance (S3); an optical cable detection step: sequentially applying a seismic power to the road surface of the detection route using the seismic source generation device, and simultaneously performing optical cable vibration detection on the detection route to determine actual breakage points (S4); and determining actual breakage segments according to the actual breakage points (S5). The detection system and method improve the detection effect and repair efficiency, and reduce the cost required for detection and repair.
