基于运动状态的学生体测监测系统设计

Design of Student Body Measurement Monitoring System Based on Motion State Detection

针对各高校学生体测时常发生的危险状况,研究了基于运动状态的学生体测监测系统。系统通过刷卡匹配学生身份,从机佩戴在学生手腕处,监测学生的心率、血氧饱和度以及运动加速度,并通过LORA将数据发送给主机。主机汇总多个从机的数据并通过串口将数据发送给上位机。采用C#编写上位机软件,调用MATLAB对接收到的数据进行卡尔曼滤波处理,判断数据范围,获得学生运动状态,并显示学生的运动数据,如果出现异常数据则进行报警。大量实验证明,该系统可在操场范围之内监测20~40名学生的运动状况,能有效预防学生体测时可能发生的危险。

In view of the dangerous situation of college students’physical test,this paper studies the student physical test monitoring system based on the state of movement.Students can swipe their cards to match their identities.The slave machine is worn on students’wrists to detect their heart rate,oxygen saturation and acceleration,and send the data to the host through LORA.The host computer collects the data of several slaves and sends the data to the host computer through the serial port.The upper computer software was writen by C#,MATLAB was used to process the received data by Kalman filter,judge the data range,obtain the students’movement state,and display the students’movement data,if there is abnormal data,alarm.A large number of experiments show that the system can monitor the movement status of 20~40 students in the playground,and can effectively prevent the possible danger of students’body measurement.
