摘要

所开发的人体-座椅表面压力测量系统合理可行，能够动态实时地测量人体和压力分布。人体座椅表面压力分布测量系统主要包括FSR压力传感器阵列和STC15F2K60S2单片机。首先，用标准砝码对FSR传感器进行标定，并绘制出不同压力输入下的输出电压曲线。STC15F2K60S2微控制器具有8个10位AD转换器。系统采用RS232串行接口与PC机进行串行通信。采用matlab进行数据处理和分析，采用带通滤波器进行噪声抑制。预处理阶段对数据进行滤波后，利用傅里叶变换对有效数据进行分析，然后利用SP Tool工具进行仿真。

Design and Analysis of Static Pressure Distribution and Measurement on Contact Interface

The developed human body-seat surface pressure measurement system is rational and feasible, and can measure the human body and the pressure distribution dynamically and in real time. The human body seat surface pressure distribution measurement system mainly includes FSR pressure sensor array and STC15F2K60S2 microcontroller. First, the standard weight scale is used to calibrate the FSR sensor and draw the output voltage curve under different pressure inputs. STC15F2K60S2 microcontroller has eight 10-bits AD converters. System adopts RS232 serial interface with the PC for serial communication. The MATLB is employed to conduct data processing and analysis, while the band pass filter is applied for noise suppression. After filtering data in the pre-processing stage, Fourier transform is used to analyze the valid data, then use SP Tool tools for simulation.
