| 摘 要： | 加速度计是捷联惯导系统的核心部件,由于捷联惯导系统恶劣的工作环境,通常以I/F转换或A/D采样方案设计的加速度计数据采集系统在测试中均有局限性,因此基于PCI04总线提出I/F和A/D相结合的方法,设计了高精度加速度计数据采集系统,该系统同时具有I/F和A/D方案的优点.从参数标定中可以看出,无论是精度、实时性、可靠性,还是动态测试范围都得到了极大的改善,其中测量精度远高于10-5g.

| Abstract: | Because of harsh environment that strapdown inertial guidance system works in,the conventional accelerator data acquisition systems(ADAS) such as I/F converter and A/D acquisition have limitations in testing.Therefore,a new method which combing I/F and A/D based on PC104 bus was proposed,and an ADAS module with the advantages of I/F and A/D schemes was designed.It can be found from the parameter calibration that the dynamic measurement range,accuracy,reliability and real-time are improved greatly.The accura... |
