摘　　要：为进一步提高155 mm火炮的射程、威力和打击精度,设计一款微型多通道弹底数据采集模块。以现场可编程门阵列(field programmabk gate array,FPGA)为设计平台,利用其内置XADC硬核,设计8路模拟信号采集转换、数据缓存与数字防干扰,对火炮发射过程中弹底多点瞬态温度、压力数据进行测量,并通过Vivado平台进行仿真分析。仿真结果表明:该模块功能参数达到设计要求,运行稳定,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 improve the firing range,power and strike accuracy of the 155 mm gun,a miniature multi-channel bottom data acquisition module was designed.Taking field programmabk gate array(FPGA)as the design platform,use its embedded XADC hard core,design 8-channel analog signal acquisition and conversion,data buffering and digital anti-interference,measure the multi-point transient temperature and pressure data at the bottom of the gun during the launching process,and carry out the simulation analysis by Vivado platform.The simulation results show that the functional parameters of the module meet the design requirements,the operation is stable,and it has a certain engineering application value,which can provide reference for the optimal design of the storage equipment of bomb bottom.
