【摘要】：液壓系統(tǒng)作為發(fā)射車不可或缺的組成部分，其液壓元件試驗(yàn)數(shù)據(jù)的有效管理是面臨的一大挑戰(zhàn)。一直以來我國車載液壓系統(tǒng)試驗(yàn)技術(shù)相對較落后，這主要表現(xiàn)在對零部件、組件和系統(tǒng)在加工、檢測、試驗(yàn)和系統(tǒng)調(diào)試過程中各階段的定量監(jiān)控和評價(jià)，更缺乏全過程監(jiān)控和定量、全面、綜合的監(jiān)測與控制。如何有序、安全、智能地管理這些花費(fèi)了大量時(shí)間和精力得來的試驗(yàn)數(shù)據(jù)，并通過可視化手段實(shí)現(xiàn)數(shù)據(jù)的使用和挖掘，同時(shí)不斷積累形成歷史試驗(yàn)數(shù)據(jù)庫，已成為支撐液壓試驗(yàn)系統(tǒng)研究的一項(xiàng)迫切需求。隨著液壓系統(tǒng)的復(fù)雜化和集成化，其故障診斷也變得十分困難，傳統(tǒng)的檢修模式已不能滿足需要，液壓系統(tǒng)智能故障診斷技術(shù)也由此變得更加重要。 在液壓系統(tǒng)性能試驗(yàn)領(lǐng)域，實(shí)現(xiàn)數(shù)據(jù)高速采集和試驗(yàn)數(shù)據(jù)有效管理，形成歷史支撐數(shù)據(jù)庫，，設(shè)計(jì)合理的故障診斷系統(tǒng)，從而使數(shù)據(jù)記錄為實(shí)驗(yàn)、設(shè)計(jì)、工藝改進(jìn)等提供重要的參考價(jià)值并且能夠快速高效監(jiān)測故障，已成為一種主流方式。本文以液壓缸為測控對象，將虛擬儀器技術(shù)、數(shù)據(jù)采集技術(shù)、數(shù)據(jù)庫技術(shù)、數(shù)據(jù)傳輸技術(shù)和故障診斷技術(shù)相結(jié)合，開發(fā)了具有多路數(shù)據(jù)采集和分析、分布式網(wǎng)絡(luò)化數(shù)據(jù)傳輸和管理、遠(yuǎn)程控制與數(shù)據(jù)查詢以及故障診斷功能為一體的液壓實(shí)驗(yàn)綜合數(shù)據(jù)管理系統(tǒng)，提出了一種分布式液壓系統(tǒng)的可視化數(shù)據(jù)處理方法。 本文的主要工作包括液壓元件性能試驗(yàn)綜合數(shù)據(jù)管理系統(tǒng)總體方案研究和關(guān)鍵技術(shù)研究以及系統(tǒng)軟件設(shè)計(jì)和性能測試。采用軟硬件相結(jié)合的方式，將傳感器采集到的模擬信號(hào)經(jīng)過調(diào)理模塊濾波、降噪等處理后，傳輸?shù)紸/D轉(zhuǎn)換器轉(zhuǎn)換，通過數(shù)據(jù)采集卡傳輸?shù)杰浖到y(tǒng)中進(jìn)行分析、存儲(chǔ)、監(jiān)控等處理。軟件系統(tǒng)分為三個(gè)子系統(tǒng)，實(shí)時(shí)數(shù)據(jù)管理子系統(tǒng)、歷史數(shù)據(jù)管理子系統(tǒng)和故障診斷專家子系統(tǒng)。該系統(tǒng)基于LabVIEW平臺(tái)設(shè)計(jì)實(shí)現(xiàn)了數(shù)據(jù)的高速采集和存儲(chǔ)，數(shù)據(jù)的時(shí)域和頻域分析，遠(yuǎn)程監(jiān)控和查詢以及故障診斷。采用模塊化理念，提高了系統(tǒng)的開發(fā)和管理效率。通過實(shí)驗(yàn)和測試，證明了系統(tǒng)是有效和可靠的。
[Abstract]:As an integral part of the launching vehicle, the hydraulic system is an integral part of the launching vehicle, and the effective management of the test data of its hydraulic components is a major challenge. The test technology of the on-board hydraulic system has been relatively backward for the long time, which is mainly manifested in the quantitative monitoring and evaluation of components, components and systems in the process of processing, testing, testing and system debugging, and the whole process of monitoring and quantitative and comprehensive, Comprehensive monitoring and control. It is an urgent need to support the research of the hydraulic test system. With the complication and integration of the hydraulic system, the fault diagnosis of the hydraulic system becomes very difficult, and the traditional maintenance mode is not sufficient, and the intelligent fault diagnosis technology of the hydraulic system becomes more important. in that field of the performance test of the hydraulic system, the effective management of data high-speed acquisition and test data is realized, a history support database is formed, a reasonable fault diagnosis system is design, The meter, process improvement, etc. provide important reference value and can quickly and efficiently monitor the fault, has become a mainstream party By combining virtual instrument technology, data acquisition technology, database technology, data transmission technology and fault diagnosis technology, a multi-channel data acquisition and analysis, distributed network data transmission and tube are developed by combining virtual instrument technology, data acquisition technology, database technology, data transmission technology and fault diagnosis technology. The hydraulic experimental comprehensive data management system, which is integrated with the data query and the fault diagnosis function, presents a visual data-processing party of the distributed hydraulic system. Method. The main work of this paper includes the general scheme research and key technology research of the comprehensive data management system for the performance test of the hydraulic components and the design and performance of the system software. It can be tested. After the analog signal collected by the sensor is processed by conditioning module filtering and noise reduction, the analog signal collected by the sensor is transmitted to the A/ D converter for conversion after being processed by the conditioning module filtering, noise reduction and the like, and the data acquisition card is transmitted to the software system for analysis, storage and monitoring. The software system is divided into three subsystems, real-time data management subsystem, historical data management subsystem and fault diagnosis expert The system based on LabVIEW platform is designed to realize the high-speed acquisition and storage of data, time-domain and frequency-domain analysis of data, remote monitoring and query, and so on. Obstacle diagnosis. The modular concept is used to improve the development and management of the system. The efficiency of the system is proved by the experiment and the test.
