| Abstract: | Aiming at the lack of I/O numbers of the controller in laser screen coordinates measurement,the parallel acquisition and control of high speed and intensive multi-channel optical signals are implemented,by combining field programmable gate array(FPGA) devices with MCU(Micro-Controller Unit).FPGA is used as acquisition and storage devices of a photoelectric switch signal data,MCU controls FPGA,processes and displays the data.After a test for the target coordinate of 7.62 mm projectile,the result proves that the system based on FPGA and MCU to implement parallel acquisition and control of high speed and intensive multi-channel optical signals solves the shortcomings of I/O shortages and low processing speed of traditional coordinates target.The system has the advantages of fast response,high sensitivity and split joint. |
