摘　　要：针对目前广泛应用的滚珠丝杠螺旋线误差检测系统的不足,对传统测量仪器进行了改造,以长光栅作为长度测量基准,圆光栅作为角度基准,设计以现场可编程门阵列(FPGA)为核心电路的计算机测量系统方案。FPGA完成测量信号的逻辑转换和数据测量,数据的处理、显示和通讯等由51单片机完成。测量过程中螺旋线误差和测量位置可在屏幕实时显示,系统稳定性好、测量效率高。Owing to the defects of detecting system of ball screw which widely applied at present, an improved computer controlled method on dynamic measurement is presented which based on the field programmable gate array （FPGA）. This method employs long raster as length benchmark and round raster as angle benchmark. The FPGA fulfills logistic conversation and data measuring. Disposal, display and communication of the data are completed by using 51 single chip. The system can display helical line error and displacement on screen, which has well stability and high measuring efficiency.
