摘　　要：为了医生能够准确获取被测者的平衡能力的健康信息,本文设计了一套人体平衡能力测试系统.根据力矩平衡原理计算人体重心坐标,提出了利用包络面积算法计算人体重心坐标包络面积的方法.本系统含嵌入式测试系统、客户端人机交互系统和医师监控系统.嵌入式测试系统对人体重心坐标移动范围及人体躯干数据进行采集并判定其平衡能力;Android客户端人机交互系统实现信息展示并上传数据至医师监控系统;医师监控系统将得到的病人的平衡测试数据上传至数据库进行持久保存.经过多次静物及人体对比测试表明:随着被测物体质量的增加,测量误差逐渐趋于零,验证了测试系统的准确性与稳定性,并且人机交互良好,可以辅助医生判断分析被测者的平衡能力.In order to accurately obtain the health information of the balance ability of the testees,a set of human body balance test system was designed.According to the principle of moment balance,the calculation of human body weight center coordinates was proposed.The method of calculating the envelope area of human body weight center coordinates by using the envelope area algorithm was proposed.The system included an embedded test system,a client human-computer interaction system,and a physician monitoring system.The embedded test system collected and determined the balance ability of the human body weight coordinate movement range and the human torso data;the Android client human-computer interaction system realized information display and uploaded data to the physician monitoring system;the patient monitoring system would obtain the patient's balance test data.The data was uploaded to the database for persistence.After many times of still life and human body contrast test,the measurement error gradually approaches zero with the increase of the mass of the measured object,which verifies the accuracy and stability of the test system,and the human-computer interaction is good,which can provides an auxiliary role for the doctor in judging and analyzing the balance ability of testees.
