[0002] In outdoor sports, the Myanmar bridge is a commonly used project. In this project, there are 3 main steel cables arranged in parallel, one of which is at the bottom for walking, and the other two are at the top for students to grasp with both hands. live; this project can exercise the students' courage, physical coordination ability, and it is exciting, thrilling and interesting; for the sake of safety, a safe steel cable is set up at high altitude, and the safety belt hangs from the steel cable and is tied to the waist of the students. However, this safety belt is heavy, and the friction between the safety belt and the steel cable at the top is relatively large, so this safety protection device brings great burden and inconvenience to the students

The invention discloses a light intensity detection-based automatic following method. The light intensity detection-based automatic following method comprises the following steps: step 1, light intensity detection: polling and detecting light intensity signals obtained by each light intensity sensor by an MCU (Micro Controller Unit) through a one-out-multiple switching switch and an A / D (Analog to Digital) converter; finding out a light intensity sensor i corresponding to a strongest light intensity signal; step 2, calculating an angle of a target object relative to a walking vehicle, wherein the angle is as follows: a=(i-1)*A / (N-1), N is the total number of the light intensity sensors, the angle unit is degree, A is the angle of an arc surface, and the horizontal direction is used as 0 degree; step 3, calculating the distance S which is required to walk, wherein S=L*tan(a), tan(.) is a tangent function, and L is the vertical distance from a guide rail to the target object; step 4, driving the walking vehicle move at S by the MCU; then returning to step 1, and carrying out control in a next round. The light intensity detection-based automatic following method disclosed by the invention is ingenious in structure, is capable of automatically following and is high in automation degree.
