摘　　要：设计了一种可以测试2min原地高抬腿和30s坐站动作的可穿戴集成系统。检测方法采用改进的自适应峰值计次算法,该算法根据测试者做高抬腿和坐站动作时的周期性加速度,确定加速度阈值,再结合计次频率实现不同动作下的自适应计数。测试结果表明:该算法能够自动识别并去除不标准动作,计次准确率基本满足体质检测的要求。A wearable integrated system is designed to test in-place legs uplifting of two minutes and sitting&standing of 30 seconds.The detection method uses an improved adaptive peak metering algorithm.The algorithm determines the acceleration threshold according to the periodic acceleration when the tester doing the actions of in-place legs uplifting,sitting and standing,and then combined with metering frequency,realize the adaptive metering under different actions.The test results show that the algorithm can automatically identify and remove the nonstandard actions,and the accuracy of metering basically meets the requirements of physique detection.
