A Design of Long Jumping Device Based on Infrared Scanning and Data Collecting Technology

摘要

A standing long jump device based on infrared scanning technology was proposed for the aim of detecting and analysing the sports achievement of a group of people. The equipment is make of a standing long jump range finder, an infrared scanning range device, and a cloud platform for data management. The output of the measurement data is achieved through converting electrical signal produced by the instrument into a digital signal. The triangular formula and the minimum value algorithm were applied to deal with the distance data measured by the infrared light device. The function model of instantaneous data acquisition can effectively solve the measurement errors caused by the slight movement of tester’s toes or heels. In addition, the device also has intelligent cross-line alarm function. Compared with the previous rangefinder equipment, this device can achieve a high level of measurement accuracy and upload real-time data to the cloud platform for analysis.
