[0002] In modern industrial automation systems, accurate displacement signal transmission is particularly important for mobile devices running along tracks, especially position feedback at critical stopping positions or acceleration and deceleration positions, which is one of the key technologies to ensure the safe and efficient operation of mobile devices.

[0003] At present, in order to achieve precise positioning and signal transmission of mobile devices at key positions, traditional displacement signal detection methods mainly rely on photoelectric sensors and magnetic switches; when photoelectric sensors are used for position detection, several gratings or reflectors are set on the track. When the mobile device passes these positions, the sensor detects the change in light and triggers the corresponding signal; when magnetic switches are used for position detection, magnets are installed at key positions of the track, and the mobile device is equipped with a magnetic sensitive element. When the two are close, a magnetic field change will occur, thereby triggering a signal.

[0004] However, traditional photoelectric sensors and magnetic switches may be affected by environmental factors (such as dust and electromagnetic interference) and cause misjudgment or failure, which often results in the mobile device not sending or sending displacement signals in time after moving to the corresponding position, causing problems in the subsequent control process. Therefore, how to improve the reliability and accuracy of displacement signal detection has become a technical problem that needs to be solved urgently. Summary of the invention
