| Abstract: | A method of PCI bus data acquisition based on the RTOS VxWorks is proposed to improve the frequency of data acquisition in the laser gyro inertial measurement system,to achieve higher measuring accuracy,and to get better results of navigation.The hardware diagram of the system is introduced,and the VxWorks program of controlling PCI bus is analyzed.Hardware design and software solution are described in details.The experimental result indicates that this method can meet the high speed,real-time and reliable requirements of the system and has a higher data transmission speed than ISA bus. |
