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.
