[0005] The second one is track geometry measurement vehicle monitoring: a special track geometry measurement vehicle is used to detect the geometric state of the track by high-precision sensors, including height, level, gauge and other parameters. It can quickly and accurately detect the position and degree of track bed heave.

[0006] The third one is automatic monitoring, which installs fixed sensors (such as displacement sensors and strain gauges) at key positions of the track bed to monitor the changes of the track bed in real time. For example, Chinese patent CN 109343548 A transmits data to the monitoring center through wireless transmission to realize remote real-time monitoring and early warning.
