设计了电场式时栅位移传感器信号处理电路的硬件平台，阐述了整个硬件平台的设计与研制过程。该平台以SOPC技术为基础，在单片FPGA上实现整个硬件平台系统的构建，将信号的采集、处理和传输集成在单片FPGA上，电路简单、稳定性好。将该信号处理电路用于电场式直线位移传感器实验系统，在数据未经修正的情况下，在200mm测量范围内传感器的误差峰峰值为0．8μm，表明该信号处理电路实现了对电场式时栅40kHz的信号的高性能处理，从而实现了电场式时栅位移传感器的高精度、实时测量。

A hardware platform design of the signal processing circuit for electrical field time grating sensors was proposed, and the design principles were introduced. This platform is based on the SOPC technology, and the single FPGA chip integrates the sig- nal acquisition function, signal processing function and signal transmission function. This hardware platform is applied to the linear displacement measurement experiment of the electrical field sensor. As a result, the original peak-peak error is 0.8 μm without any correction in 200 mm measurement range ,which proves the high performance of proposed signal processing circuit for the electrical field time grating sensor with the 40 kHz exciting signal.
