When the walking stick 1 is viewed from the side, the forward diameter from the connecting portion (50) with the shaft (20) to the front end of the first ground contact portion (31) and the rear diameter from the connecting portion (50) with the shaft (20) to the rear end of the second ground contact portion (32) are different.

The invention discloses a passenger unsafe behavior recognition device and method for a special equipment scene, and relates to the technical field of special equipment safety monitoring. The device comprises a sensing unit, a data transmission unit, a data processing unit and a man-machine interaction unit. Passenger videos and equipment data are collected through the sensing unit, key points of passengers are extracted through a YOLOv11 posture estimation model in the data processing unit, and five unsafe behaviors including falling, squatting, backward walking, border crossing and overcrowding are accurately recognized in combination with behavior judgment logic customized for special equipment scenes. An identification result is displayed in real time through the man-machine interaction unit and is fed back to the special equipment control system through the data transmission unit, and closed-loop safety control of perception-analysis-decision-execution is formed. According to the invention, the problems of low identification precision, poor scene adaptability and lack of real-time linkage capability in the prior art are solved, and the safety and intelligent level of operation of the special equipment are remarkably improved.

This utility model discloses a backward walking rearview alarm sports waist pack to solve the problems of untimely and inaccurate collection of road condition information within one step behind during backward walking. The utility model includes a waist pack body, with a camera and radar probe at the front. Inside the waist pack body is a main unit and an adjustment column connected to the rear of the camera, with the rear end of the adjustment column tilted. The radar probe is connected to the main unit, and both the camera and the main unit are connected to a mobile terminal. This utility model centrally installs the components inside the sports waist pack. When walking backward, the user wears the waist pack and uses the camera and radar probe to accurately detect the road conditions behind them, especially providing precise visualization of the road conditions within one step behind, voice prompts for obstacle distances within 2.5 meters, and a buzzer alarm when obstacles approach. The user can directly observe the road behind them and hear the obstacle voice alarm without turning around via a handheld display screen or smartphone, providing safety assurance for backward walking.
