Design of Incremental Encoder Signal Acquisition System Based on FPGA

针对电磁测量和伺服控制系统中使用增量式编码器实现位移和速度测量的应用场景,设计基于FPGA的增量式编码器信号采集系统,实现增量式编码器信号倍频鉴向、脉冲计数、UART串口数据传输功能,使用QuartusⅡ和ModelSim软件进行联合仿真,验证了基于FPGA的增量式编码器信号采集系统的功能。

This article is mainly aimed at the application scenarios of using incremental encoders to achieve displacement and speed measurement in electromagnetic measurement and servo control systems.An incremental encoder signal acquisition system based on FP-GA is designed to realize incremental encoder signals.Frequency multiplication direction discriminating,pulse counting,UARTF serial port data transmission function,and using QunrusⅡand Mode Iim software for joint simulation to verify the function of the FPGA-based incremental encoder signal acquisition system.
