Research on the development, design and marketing of infrared ranging seated forward bending equipment

In recent years, along with the continuous improvement of China’s national living and economic standards, the physical quality of the people has been generally improved, and the Chinese Government has carried out a comprehensive and systematic strategic plan centered on the promotion of the construction of a strong sports nation. As an important part of the national population, the physical quality and physical and mental health of college students are extremely important. In order to implement the accuracy and efficiency of the data of college students’ physical fitness test, this paper takes the seated forward bending program as the starting point of the physical test process, combines the infrared ranging technology with the posture fixation mechanism, avoids the inaccuracy of the data due to the inertia and posture bending, and ensures the accuracy of the data of the physical test, improves the efficiency of the test, and reduces the workload of the teachers. At the same time, the potential market and development prospects of this device are evaluated by analyzing the data of the audience groups that this device is aimed at [1].
