摘要
为保证惯导组件测试系统安全、可靠的运行,该文基于实际工程项目设计了一种应用于惯组测试系统中的自检自校系统。采用基于FPGA实现的惯导组件模拟信号发生器、数据采集与数据传输作为硬件测试平台,以Windows平台下的图形化可编程语言LabVIEW作为软件测试平台。该系统可以模拟仿真在不同测试状态下惯导组件的工作情况,以实现在没有转台,没有被测产品的条件下测试系统能够进行自检自校,并指示系统可能存在的缺陷和故障,提高系统检测智能化和自动化程度。现已应用到实际工作中,测试结果表明该系统的正确性和稳定性,具有重要的实际工程应用价值。
In order to ensure that the IMUTS（inertial measurement units test system）can work safely and reliably op- eration,based on the actual project,a kind of self-test and self correction system was designed and realized. The system＇s hardware test platform consists of IMU analog signal generator,data acquisition and data transmission,which were designed by using FPGA. LabVIEW,which was a programmable and graphical language under Windows plat- form,was used in the system as software test platform. The system can not only simulate the performance of IMUTS under different test conditions,but also can find out the possible defects and faults of the system without turntable or products. In this way,it can enhance the intelligence and automation. Test results indicate that the system can work with accuracy and stability and has important engineering application value.
