摘　　要：针对导弹捷联惯性测量组合的输出特点,基于嵌入式PC/104总线和可编程定时/计数器82C54芯片,设计了一个惯性测量组合数据采集系统,并利用复杂可编程逻辑器件(complexprogrammablelogicdevice,CPLD)设计了数据采集的接口电路,实现了对捷联惯性测量系统输出数据的动态、实时采集。实验证明,该采集系统方案是可行的,达到了设计要求。According to the characteristic of SIMU (strap-down inertial measurement unit), a data acquisition system of IMU (inertial measurement unit) based on PC/104 bus and programmable timer 82C54 chip is designed. The electric interface of the system is also designed with CPLD (complex programmable logic device) technique. Dynamic and real-time collection of the output data of SIMU are realized. The test of the data acquisition system shows that the project and design of the system are feasible and can meet the practical demands.
