The Design of 12-Channels Acquisition and Storage System Based on FPGA and AD7492

This paper introduces the principle and realization process of multi-channel data acquisition and storage system based on FPGA, A/D converter, FLASH and USB microcontroller. The system’s controlling core is FPGA. FPGA finished the switch of the multi-channel analog switch、A/D conversion、data compilation and storaging in the FLASH and uploading the data to PC by USB microcontroller. Test result can indicate that the system is simply and practical .The system can finish the real-time acquisition and processing for 12 input signals, sampling rate up to 1MSPS.

The high-altitude missile and other special application occasions have requirements on image storage system, such as small size, high storage speed, low temperature resistance, etc. Commonly used image storage system in the market cannot meet such requirement. In the paper, real-time image storage system solutions on missile based on FPGA should be proposed. The system mainly consists of acquisition module and memory reading module. The whole system adopts FPGA as main control chip for mainly completing real-time decoding and acquisition on one path of PAL format video images, reading and writing of NandFlash chipset, erasure, bad block management and so on. The solution has passed various environmental tests with stable performance, large data storage capacity and easy expansion, which has been used in engineering practice.
