基于FPGA的片上多通道采集模块设计

Design of FPGA-based on-chip multi-channel acquisition module

为进一步缩小某型号火炮弹底数据采存设备的体积、提高火炮的射程、威力、打击精度以及采存设备的采集和处理性能,在单片FPGA芯片内设计实现多通道数据采集模块。以Xilinx公司Artix-7系列FPGA为设计平台,利用其内嵌的XADC硬核,采集转换8路外部模拟电压信号并实现FPGA芯片内部温度、关键电压监控。设计在Vivado平台进行综合实现与仿真,仿真结果表明,该模块功能参数满足设计要求且后续可定制性强,具有一定的工程应用价值,可为弹底采存设备的优化设计提供参考。

In order to further reduce the volume of the data acquisition and storage equipment at the bottom of a certain type of gun,improve the range,power,strike precision of the gun,and the acquisition and processing performance of the acquisition and storage equipment,a multi-channel data acquisition module is designed and implemented in a single FPGA chip.Taking Xilinx′s Artix-7 series FPGA as the design platform,using its embedded XADC hard core,it collects and converts 8 external analog voltage signals and realizes the internal temperature and key voltage monitoring of the FPGA chip.The design is comprehensively implemented and simulated on the Vivado platform.The simulation results show that the functional parameters of the module meet the design requirements and the subsequent customization is strong.It has certain engineering application value and can provide a reference for the optimization design of the bottom of the bomb.
