摘要

针对工作空间测量定位系统( wMPS)等基于光电扫描的测量网络对光平面信息检测的要求,提出了一种基于可编程器件的光平面信息检测与区分的系统.该设计使用Xilinx公司的Zynq芯片,在FPGA中设计逻辑电路实现对光平面的电脉冲信息捕获与锁存,并设计符合AXI总线通信协议的IP核增加通信速度.通过仿真表明,该设计具有时间开销小、实时性强等优点,提高了系统效率,同时可应用于其他光学定位设备中,提高定位精度.%Aiming at the requirement for detecting and processing the information of laser pulse in the optical scanning measurement network such as workspace measuring and positioning system, a system based on programmable logic device that can detect and discriminate the laser pulse information has been proposed. Using the Zynq chip produced by Xilinx, the system designs logic circuit in the FPGA to capture and latch the laser pulse information, and it also has the IP module based on AXI bus protocol to accelerate the communication speed. The simulation shows that this design has little time overhead and can operate in real-time system, therefore increases the efficiency of the measuring system. It can also be used in other optical equipments for the use of navigation orientation system, to increase the positioning accuracy.
