Design of Real-time Data Acquisition System for Physical Education in Elementary and Secondary School

摘要

At present, the physical education in elementary and secondary school lacks real-time data acquisition system, which resulted in obstacles to relevant researches. In this paper, a real-time sports data acquisition system for multiple students is proposed. Combined with wireless communication technology, the paper designs and develops a sports data collector and wireless base station for receiving data. The process of data communication utilizes MINA frame. Also, a complete set of Socket-based data transfer protocols is defined. The system not only provides researchers with reliable data, but also enables PE teachers to monitor students' physical exercise in real time. Through the computer stimulation test and field test, both the performance and the availability of the system are verified.
