AI Technical Summary
Existing coupler status detection devices have limited functionality and an unreasonable sensor unit layout, making them susceptible to mechanical interference during coupler movement. This results in unstable detection signals, poor accuracy, and an inability to provide timely and reliable status information, thus affecting train safety.
A coupler status detection device is designed. Multiple sensing units are set up to detect the deflection or contact status of the coupler at different positions. The coupling status of the coupler is judged by combining the feedback signals of multiple sensing units. A combination of a first sensing unit, a second sensing unit and a controller is adopted to form a coupling mechanism detection loop and a coupling surface detection loop, thereby improving the detection accuracy.
It effectively improves the accuracy and reliability of coupler condition detection, reduces the failure rate of detection devices, reduces the cumbersome process and human error of manual inspection, and improves the safety and efficiency of train operation.
