Description

Altitude touch measuring device based on infrared detection

Technical Field

The application relates to the field of sports measurement characterized by an optical method, in particular to a measuring device for measuring the touch height based on infrared detection.

Background

At present, most of domestic measuring devices for measuring the touch height adopt touch sensors, generally adopting a resistance type or capacitance type or adopting an infrared laser mode for detection. Resistive touch sensors suffer from the disadvantage that the process of converting a change in pressure caused by a touch to a change in voltage by the sensor is relatively slow. In addition, when a person jumps to the highest point and feels high, the touch force which can be responded by the sensor cannot be achieved. These two effects can lead to reduced accuracy of the high-reach measurement. Also the lifetime of the sensor is affected by frequent tapping of the measurement area. Although the capacitive touch sensor is sensitive, due to the characteristics of the capacitive sensor, when a measurement area is wet or covered with liquid, touch sensing may malfunction or malfunction, and the accuracy of touch-up measurement may be reduced. The infrared laser mode belongs to a non-contact sensing mode, and the touch position is measured by transmitting and receiving a plurality of infrared lasers, so that some negative effects caused by resistance or capacitance are eliminated. However, the infrared laser tube emits light, so that the emitting tube and the receiving tube are difficult to align, and once the design, the manufacturing process and the precision of the external structure of the fixed lamp tube or the assembly have deviation, the emitting and receiving tubes are always misaligned, and the normal altitude touch recognition is influenced. In addition, the existing height measuring device generally utilizes the self structure to realize the use height, and has the conditions of large volume and heavy weight.
