Embodiment approach
[0063] Embodiment: An operating handle for automatically following a suitcase, which includes a handle, a distance sensor, a front-end signal processing circuit, and a controller. When the user holds the handle, the distance sensor outputs an induction signal; the front-end signal processing circuit is responsible for amplifying, calibrating, filtering and other signal processing work on the signal output by the distance sensor, and outputs the RS232 signal to the automatic luggage tracking system in the controller . The distance sensor is installed at the front and rear ends of the handle parallel to the box body, and the distance sensor is embedded in the surface of the handle and integrated with the surface of the handle. The distance sensor has a sensing distance of 5-10mm. When the user holds the operating handle or the hand is within the sensing distance, the sensor outputs a continuous high-level signal. The front-end signal processing circuit is located inside the han...
