摘　　要：对飞轮转子位移信息的采样检测是保证飞轮储能系统(FESS)高速、稳定运行的关键。利用数字信号处理器(DSP)的计算能力和现场可编程门阵列(FPGA)的并行处理能力,采用主从设计方式,提出了一种基于DSP和FPGA的多通道、高速采样系统的实现方法;阐述了系统的模块功能、硬件布局、软件设计以及对高速AD芯片THS1207的控制方式。实验证明了设计的系统能够实现多通道、高速采样的要求。The sampling examination of flywheel rotor displacement information is the key for ensuring high-speed and stable operation of fly wheel energy storage system（ FESS）. Based on the calculation ability of digital signal processor（ DSP） and the parallel processing ability of field programmable gate array（ FPGA）,adopting master/slave design mode,a multi-channel,high-speed sampling system realization method based on DSP and FPGA is proposed. Module function,hardware layout and software design of the system as well as control mode for highspeed AD chip THS1207 are elaborated. It is proved by experiment that the desiged system can achieve requirements of multi-channel and high-speed sampling.
