All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The infrared receiver 22 receives the infrared beam output from the infrared transmitter 21 and outputs an electrical signal when the infrared beam is blocked.

The carriage assembly 10 is configured as a rigid structure for mounting and supporting the elevation plate 30 and the sensing assembly 20 to stabilize the operating position of the sensing assembly 20. The carriage assembly 10 is positioned in a reference plane such that the elevation plate 30 is in an upright position relative to the reference plane in which the carriage assembly 10 is positioned. The reference plane may be a ground of a sports field, a ground of a building, a takeoff plane of a target person, or the like.

The infrared transmitter 21 is used for outputting infrared light, and the infrared receiver 22 is used for sensing the infrared light output by the infrared transmitter 21 to form an infrared beam. The height-touching space is located between the infrared receiver 22 and the infrared emitter 21, and forms a U-shaped space with the height-touching board 30. An infrared beam is output from infrared transmitter 21 and received by infrared receiver 22 to spatially separate the heights and form successive measurement zones to represent different heights of the heights. Optionally, the infrared beam is parallel to the reference plane to constitute a nominal height relative to the reference plane. When the target person is performing the altitude touch test, the finger blocks the infrared light, so that the infrared receiver 22 cannot receive the infrared light, and the altitude touch of the target person can be determined to correspond to the calibration height corresponding to the infrared light. Of course, the sensing assembly 20 outputs an infrared beam, which can be used to test whether the reach height of the target person is qualified. When the sensing assembly 20 outputs two or more infrared beams, it can be used to test different heights of the target person.
