In the process of ground test and flight test,the aircraft widely uses pulse code modulation (PCM) technology to realize high-speed acquisition and stable transmission of telemetry data.Aiming at the requirements of high transmission speed,high capacity and strong real-time of telemetry data,a PCM data test system based on Zynq7020 is designed.The system takes Zynq7020 as the main control center,communicates with the upper computer through the CPCI bus,simulates the missile equipment sending LVDS data to the telemetry acquisition and coding transmission device,and realizes real-time high-speed acquisition and storage of two way PCM data.Through repeated tests,it is verified that PCM data does not have any frame loss,which can meet the needs of aircraft ground test.
