本项目在国家自然科学基金面上项目“柔性人体动力学建模分析与仿真研究”(No.61673369)的支持下，设计一款能够检测不同力度、频率及作用时间的力学刺激，并以图像的形式实时显示的压力检测系统。该压力检测系统使用FSR薄膜压力传感检测外力信息，利用STC12C5A60S2单片机实现数据的处理和发送，并在上位机进行显示。系统模块包括压力检测模块、信号调理模块、信号处理模块，以及图像显示模块。通过信号采集、滤波、放大及AD转换等，最终在PC机上以图表的方式对所测力进行实时显示，具有较高的实用价值。(Under the support of the surface project "Modeling analysis and simulation study of flexible human dynamics"(No.61673369) of the National Natural Science Foundation, this subject designs a system which can detect the different mechanical strength, frequency, and action time of the mechanical stimulation, and this system can display the date in real time in the form of images. The pressure detection system uses the FSR thin film pressure sensor to detect external force information, and this system uses STC12C5A60S2 single-chip microcomputer to process and send data which will be displayed on the upper computer immediately. The system contains the pressure detection module, the signal conditioning module, the signal processing module, and the image display module. Through signal acquisition, filtering, amplification and AD conversion, the measured force is finally displayed on the PC in a graphical way. The system is of high practical value.)
