| Abstract: | The data collection system based on the technology of the field programmable gate array(FPGA) is introduced.The FPGA is utilized as the core controller for the angular measurement system,in which there is a counter with six independent channels and each channel has a counting capacity of 2~(24).This system overcomes the drawbacks of the measurement systems which are based on common integrate circuits,such as complex circuits and larger PCB area.The composing principle of the counter,the real-time counting of each channel,the communication with the host computer using the MCU,and the hardware and software of the data collection system are described. |
