摘要
论文对包装箱振动信号采集与监控进行了研究,提出了在LabWindows/CVI环境下开发基于虚拟仪器的航天器包装箱振动测试系统,用软件编程替代传统测量仪器的硬件电路,降低了测试成本。LabWindows/CVI集成了大量可视化控件以及数据采集和分析函数库,为系统提供了形象友好的操作界面,同时提高了开发效率。
本系统主要包括数据采集、文件管理、数据分析及其他功能四个模块,实现了快速、稳定、长时间的数据采集和基于Quinn频率估计法的高精度频谱分析,为包装箱的减振效果提供了实验依据,保障航天器的运输安全。
本系统已投入使用,经实际测试,证明该系统测试准确、稳定可靠、抗干扰能力强。该系统所需设备少,自动化程度高,它改变了原来测试系统中各台仪器独立使用、手动操作、人工记录数据、自动化程度较低的状态。
In this paper, we developed a spacecraft packing chest vibration measurement system based on virtual instrument in LabWindows/CVI development environment, after studied the packing chest vibration signal acquisition and control. Due to software programming instead of the traditional hardware circuits of measuring instruments, reduced the cost of test. LabWindows/CVI integrates a large number of visualization controls, as well as data acquisition and analysis functions, provides a friendly and easy used user interface for the system, and improving development efficiency.
In this system there are four modules, such as data acquisition, file management, data analysis, and other functions. Achieving a rapid, stable and long period of data acquisition and high-precision frequency spectrum analysis based on the method of Quinn estimating frequency. Provided experimental basis for the damping effect of the packing chest, and protected the spacecraft's transport safety.
The system has been put into use, the actual tests to demonstrate that the system testing accurate, stable and reliable, and with strong anti-jamming capability. It changes the past measurement system with instrument independent, hand-operation, hand record data, low automatization operation into measurement system with few instrument, high automatization.
