A Multi-parameter Joint Warning Mechanism for Physical Condition Monitoring System in Physical Education

摘要

Background: In recent years, sudden deaths of primary and secondary school studentscaused by sports activities have drawn great attention in education and medical circles. It isnecessary for schools to monitor the physical condition of the students in order to reasonably set theduration of their physical activity. At present, the physical condition monitoring instruments used invarious hospitals are expensive, bulky, and difficult to operate, and the detection process is complicated.Therefore, existing approaches cannot meet the needs of physical education teachers oncampus for detecting the physical condition of students.Methods: This study designs a portable human-physiological-state monitoring and analysis system.Real-time communication between a wearable measurement device and a monitoring device can beensured by real-time detection of the environment and power control of the transmitted signal.Results: From a theoretical point of view, the larger the number of segments M, the more significantlythe reduction of false alarm probability. The simulation results also show this fact. Comparedwith the conventional early warning mechanism, the probability of a false alarm for the proposedsystem is lower, and the greater the number of segments, the faster its reaction speed.Conclusion: The portable monitoring system of student physical condition for use in physicaleducation of primary and middle school students proposed in this paper ensures real-time monitoringof the members within the system in an open environment, and further proposes an early warningmechanism for combining multiple vital sign parameters. In addition, the proposed system functionsfaster; the average early warning time required is only one-quarter of that of the conventional system.
