Design And Implementation Of Multiple Data Receiving And Storing Based On FPGA

The development purpose of multiple data receiving and storing based on FPGA is to obtain the flight parameters in the process of aerial aerocraft and to store the parameters. It is the comprehensive measurement which includs of data receiving, data processing, data storaging. The design of the system belong to the area of the storage measurement technology, and the research category of the solid-state storage in high-speed and high-capacity.Aiming at the present situation and development trend of the domestic and foreign high-speed, high-capacity data storage system, and combined with the system design requirements, and analysing the transmission parameters of the stored data which includes DYT image data, XMG image data, telemetry PCM data, the paper puts forward the design scheme of the system. The system uses modular approach to design. The system mainly consists of data receiving processing module and data storage module. Data receiving processing module complete DYT image data, XMG image data and telemetry PCM data real-time receiving, processing; Data storage module complete high-speed data storage, which is transmissed from data receiving and processing module.The paper introduces the interface circuit design of data receiving, including DYT image data, XMG image data and telemetry PCM data, and the realization of the data receiving in different transmission protocol and three data's timeshare storage; and introduces the hardware circuit design of data storage and the realization data storage of the high-speed data; and introduces the key technologies of the system design and analyse and validate in perspective of the theory; in the end, the paper introduce the debugging of the system design, verificate the function of the system, analyse the data and get the conclusions.The system successfully complete the data receiving, data handling and data storage in the flight of aerocraft; and get the storaged data from the storage after the aerocraft landing on the earth.
