The scraper chain breakage early warning system mainly consists of components such as a control box, signal collector, DC regulated power supply, and magnetic sensor.Adopting online non-destructive magnetic inspection technology based on the metal magnetic memory effect, it can monitor the early damage status of the scraper chain in real time, including cracks, wear, gnawing, and deformation, and accurately mark and locate damage risk points.The system continuously tracks the deterioration and evolution trend of risk points, realizing online evaluation, early warning, and precise positioning of the scraper chain.It effectively avoids production shutdowns and safety accidents caused by chain breakage faults, providing safety support for intelligent coal mining.
