| 摘 要： | 介绍了一种基于有限状态机(FSM)的高精度角度测量系统。该系统采用Renishaw高精度增量式光电编码器作为位置传感器来测量角度,在FPGA上用VHDL语言描述与仿真有限状态机,实现信号滤波与去抖,从而保证了计数器计数的正确性。在ARM9处理器上实现角度的实时计算,并控制转台旋转。在激光跟踪测量系统的工程应用中验证了该系统的正确性和有效性。

| Abstract: | This paper describes a high-precision angle measurement system based on finite state machine(FSM).The system uses Renishaw precision incremental optical encoder as a position sensor to measure the angle,using VHDL language in the FPGA to describe and simulation finite state machine,to achieve signal filtering and the shaking,thus ensuring the correctness of the counter.The ARM9 processor achieves real-time calculation of the angle,and controls the turntable rotation.In the engineering application of the laser tracking measurement system verify the correctness and effectiveness. |
