摘要
研究基于Labwindows/CVI的捷联惯导测试软件应用于激光陀螺(光纤陀螺)和石英加速度计组成的捷联惯性导航系统。对满足系统功能的CVI程序的关键编写要点作了详细介绍,主要包括多串口硬件实现及其初始化、超时等待处理,定时器使用,数据发送、接收和统计特性计算,数据实时显示更新,图形界面的生成、属性页切换实现、曲线图的绘制和纵坐标轴的动态处理,以及事后试验数据回显等。该软件已成功应用于某项目光学陀螺惯导的静态测试和环境考核等多项试验中。经多次试验验证,软件可以作为惯导产品精度考核的辅助工具。
What this paper researched is programming with Labwindows/CVI software, which is based on strap-down inertial navigation system of laser gyro or fiber gyro. There are a lot of key points of the program introduced in this paper, including the hardware of multi-serial ports, initialization of the serial ports, process of overtime, usage of the timer, sending and receiving of the data, calculation of the statistic, update of data display, use of the graphics and switch of attribute page, plotting, dynamic process of Y axis and redisplay of the data. The software has already been used in experiments of INS, and this software can be applied as an aided instrument for INS testing.
