The Remote Image Data Acquisition and Storage System Based on High-Speed FIFO

In view of the high data capacity and high-speed features of image signal,the remote image data acquisition and storage system is designed. The hardware system is composed of a FPGA for central controller and a IDT72V285 for high-speed FIFO. The data acquisition and storage system is used for acquisition,encoding,transmission and storage of two channels of image data. Subsequently,the data is read back and reconditioned in the analysis computer. The design of high-speed FIFO,writing data to FLASH and remote data reading are key parts in the overall system. On the basis of the practical tests,it is proved that the data acquisition and storage system is stable and reliable,which can satisfy the practical requirements.
