Aiming at the problem of performance testing about high-precision and high-speed optical shaft encoder in the field of aerospace,the function of display in rapid detection system based on aero-space photoelectric encoder was designed.The system could simultaneously complete acquisition,pro-cessing,communication and display of multiple optical encoders.DSP + CPLD was core processing module.CPLD controlled the high-speed A/D to complete photoelectric encoder signal acquisition and data latches coarse code.DSP was responsible for the completion of processing crude code and precise code encoder signal,data communication and display.The data information of processed was trans-mitted by the dual port RAM in the customize communication interfaces.Each of the encoder reading from RAM about the angular position in binary and degrees,minutes,seconds form were displayed in the LCD screen by external buttons controlling.The results show that the system can handle data sig-nal of multiple encoders,data transmission and display.The system is good real-time and strong visi-bility.Display function of system can be further expanded.
