一种可穿戴人体运动轨迹测评装置的液晶显示设计

基于TMS320F28335设计了一种人体运动识别与测评装置。利用运动传感器MPU6050获取人体运动姿态数据,并与标准数据相比较,能够实时提醒使用者动作的规范程度。独特的可编程教练模式,能够现场采集和处理标准数据,适用于体育训练和患者康复。该装置使用串口LCD作为显示模块,能够显示所测人体运动的加速度、角度和人体运动轨迹的测评与分析结果。给出了系统液晶显示电路的硬件设计和软件流程图。实验结果表明,所设计的显示电路模块接口简单,使用方便,体积适中,能够满足可穿戴人体运动轨迹测评的显示要求。

LCD display design in wearable motion track device

A wearable motion recognition and evaluation device were designed base on TMS320F28335. The device can remind the user action whether it was correct by compared standard data with human motion and attitude data obtained by motion sensors MPU6050. Equipped with unique programmable coach mode which enable the collection and production of standard motion data, the device is suitable for physical training and rehabilitation of patients. The serial interface LCD is used as a display panel, which can display the acceleration, angle of the human motion and evaluation and analysis results of human motion posture. The hardware design and software flow chart of the liquid crystal display circuit are given. The experimental results show that the LCD display circuit interface is simple, easy to use, moderate size, to meet the requirements of wearable human motion trajectory evaluation.
