Simulation and Design of Distance Measurement Based on GP2Y0A02

为了实现非接触距离测量,利用多个仿真与设计软件设计了采用GP2Y0A02模块的距离光学测试系统。在PROTEUS中测量GP2Y0A02电压值,并在Matlab中采用多元线性回归建立GP2Y0A02电压与距离的拟合曲线,最后在开发的测量程序中利用拟合曲线求解得到距离量。测试结果表明,对于非线性位置测量采用适当数据处理方法能得到满意的测量精度。

To realize the non-contact distance measurement, the distance optical test system based on GP2Y0A02 is designed us-ing multiple simulation and design software. The voltage value of GP2Y0A02 is measured in PROTEUS, and the fitting curve of GP2Y0A02 voltage and distance is established using multiple linear regressions in Matlab;finally distance is measured by the fitting curve with procedure. The test results show that satisfied measurement accuracy can be attained using appropriate data processing methods for the nonlinear position measurement.
