站立和步行状态下足底压力监测系统设计

Design of plantar pressure monitoring system under standing andwalking conditions

为了监测站立和步行状态足底压力变化,实现数据可视化,设计了一种足底压力监测系统。该系统由数据采集系统和数据显示系统组成。采集系统包括左右脚的采集设备,硬件电路由STM32微型计算机模块、薄膜压力传感器、蓝牙通信模块等部件构成,将硬件电路整体嵌入到鞋中组成采集设备。利用Android Studio开发显示系统的移动端软件,采集设备的数据通过蓝牙方式发送到显示系统,实现足底压力的可视化。系统测试结果表明,移动端软件配合左右脚足底压力采集设备,能够直观展现站立和步行状态足底不同位置的压力变化情况,从而为基于足底压力的分析提供数据支持。

In order to monitor the changes of plantar pressure data in standing and walking conditions and realize the visualization of data changes,a plantar pressure monitoring system was designed.The system consists of a data acquisition system and display system.The acquisition system includes the acquisition equipment for the left and right feet.The hardware circuit consists of STM32 microcomputer module,membrane pressure sensor,Bluetooth communication module and other components.The hardware circuit is embedded into the shoe as a whole to form the acquisition equipment.Mobile software of the plantar pressure display system was developed with Android Studio.The data of the acquisition system was sent to the display system through Bluetooth to realize the visualization of plantar pressure.The system test results show that the mobile software combined with the left and right foot plantar pressure acquisition equipment can intuitively show the pressure changes at different positions of the plantar under the standing and walking conditions,thus providing data support for the analysis based on the plantar pressure.
