Design and Simulation of Multichannel Dynamic Measurement Control System

The circuit system designed in this paper uses FPGA and single-chip microcomputer as the main chips. It VHDL language programming performs functional simulation verification of core control program through ModelSim software, finally, a storage-type dynamic measurement with one-to-multiple channels, adjustable trigger modes, optional sampling frequency is realized. At same time, further optimized terms power consumption volume. storage can successfully record eight-channel voltage signals, relative error experimental results less than 2% experiment Hopkinson bar loading.
