A signal sampling and wireless transmitting system for high speed piezoelectric shape meter based on FPGA was de-signed in this paper.An analog multiplexer and a high speed A/D converter were used to realize real time multi-channel analog sig-nal sampling.The FPGA system was responsible for the multiplexer and A/D converter control,data cache and processing.Then, the results were transmitted to the industrial computer with wireless system.The experimental results show that the FPGA system can satisfy the sampling and transmitting demands of a high speed piezoelectric shape meter with 10 channel piezoelectric sensors, which works at 2400 r/min.And the FPGA signal sampling and processing system has debugged in a particular shape meter,pro-ving the operation effect.
