论文中文摘要:
基于虚拟仪器矿山固定设备测试系统的研究对保障矿山安全生产,实现固定设备性能综合测试,降低测试成本,简化测试工作具有重要的意义。 论文在分析提升设备和往复式压缩机工作原理的基础上,构建了提升设备和压缩机虚拟仪器性能测试系统。通过对测试系统基本组成环节进行分析,并将各环节联接后,对离散系统连续化,得出系统数学模型,分析测试系统在时域和频域内的动态特性及分析过程中应注意的问题和解决途径。 文中对测试系统的组成环节进行了讨论选择,根据需要测试的物理量,分析确定每种物理量的测试方法。按照测点布置原则和采样原则,完成传感器的类型选择,并确定测点位置。 应用信号分析理论编制算法,实现了对噪声信号的抑止和有用信号的提取。根据性能测试要求,设计实现了各种性能测试模块,并直接显示出如提升机运动特性、提升机动力特性和压缩机示功图等性能曲线,完成了矿山设备虚拟仪器性能测试系统的设计。 对整个测试系统的主要测试功能进行了实验验证,将系统的测试结果与实际值进行比较,得到最大相对偏差为±1%,说明该虚拟仪器测试系统满足测试精度的要求,可以用于提升设备和压缩机的性能测试。 对该系统的幅频响应数据,应用系统辨识的方法,通过实验确定系统模型参数,并对系统进行时域和频域内的特性分析,得到系统的频率响应、阶跃响应和稳定性情况,在理论上说明了该系统可以用于现场测试。
论文外文摘要:
It is important to ensure mine production, actualize mine fixing synthesis testing, decrease the test cost, and predigest test work of test system based on virtual instrument. After the introduction of the principle of mine winder and compressor, the test system has been constructed in the paper. Link the system element, continue the system, and the system model has been gained after analyzing the essential composed elements. This paper discusses the essential composed elements of the test system, analyses and fixes the test methods of every parameter’s according to need. Furthermore, the type of sensors and the location of the test points are fixed in the light of principle of test point disposal and sampling. The noise is suppressed and the available signal is picked-up according to the principle of signal analysis. The article has designed several test modules basing on test requirement, and the kinematics characteristics charts and dynamic characteristics charts of mine winder, the indicated diagram of compressor have been showed. Finally,the design of mine fixing test system based on Virtual Instrument has been achieved basically. Make the experiment validate to the whole test system for main test function, comparing the test result with real value, the maximum relative warp gained is ±1%, which less than the maximum warp allowed±3%, which illuminate the virtual instrument test system content the test precision requirement and can be applied in the performance test of mine winder and compressor. By adopting the model identification algorithm to system amplitude response, the model parameters are fixed after experiments. Make the system analysis in time-domain and frequency domain, gain the frequency response, step response and stability analyses, which show that the test system can be applied in actual test.
