The automatic evaluation system based on open source hardware of endurance running in senior high school entrance physical examination

Based on open-source hardware, a set of automatic evaluation system of endurance running items was designed, which aims at the problem that the hand timing of endurance running items is not accurate enough. The system can be applied to the daily physical education training as well as the test every school year and Senior High School Entrance Physical Examination. The system is divided into basic version and test version. The basic version is mainly composed of UNO, LCD screen, voice module, clock module, rotary potentiometer, infrared beam module, etc. The test version is mainly composed of ESP32-CAM and human body infrared sensor. In Arduino IDE, C language program is written to achieve the design and development of the whole system. The system uses variable and array flexibly to record various rating tables and marking patterns, and the system test data is better than manual timing. The whole system is simple and practical. The future improvement direction of the system is to further optimize the system and add the function of automatic circle recording.
