      Onboard High Precision Pressure Data Acquisition System Based on FPGA

      摘要:
      以FPGA为核心,设计了一种由传感器、信号调理电路、数据采集控制以及存储器组成的小型弹载数据采集系统;采用8515C-50型压力传感器和AD7606芯片采集压力数据,而后通过FPGA进行数据处理与存储,并且提供上位机接口便于数据导出;对主要模块进行测试与仿真,结果表明:采集精度与速度满足设计要求,FPGA各模块设计功能完整,验证了该方案的可行性;为新型智能弹药的测控系统设计奠定了技术基础,具有重要的工程实用价值.
      Abstract:
      Aiming at the high speed and high precision requirements of adaptive-ammunition's flight data acquisition,but the problem of traditional MUC system's slowly speed,measurement accuracy is not enough,anti-interference ability is poor,we designed a small onboard data acquisition system consists of sensors,signal conditioning circuit,data acquisition controller and memory.Using pressure sensor 8515C-50 and AD7606 acquire pressure data,and then using the FPGA to data processing and storage,and it can export data through host computer interface.The main modules are tested and simulated,and the results show that the acquisition accuracy and speed meet the design requirements,each module of the FPGA designed function is complete,and finally we verify the feasibility of the design.For the measurement and control system design of the new intelligent ammunition,it lids the technical foundation and has important engineering practical value.
