    摘要:

    航空發(fā)動(dòng)機HMU是發(fā)動(dòng)機燃油控制系統中的一個(gè)關(guān)鍵單元,主要作用是根據發(fā)動(dòng)機電子控制器的輸入要求對燃油增壓、計量以及伺服作動(dòng),為發(fā)動(dòng)機提供燃油,確保發(fā)動(dòng)機發(fā)揮其最佳性能,為保證其產(chǎn)品在生產(chǎn)過(guò)程中更高效率、更高精度的試驗及交付過(guò)程,需要進(jìn)行智能化試驗系統交付平臺的設計,從而消除因人工主觀(guān)因素對產(chǎn)品的影響,針對整個(gè)系統進(jìn)行網(wǎng)絡(luò )部署和技術(shù)架構進(jìn)行研究,分別采用硬件和軟件兩方面進(jìn)行升級配置,基于LabVIEW軟件進(jìn)行算法程序編輯,并創(chuàng )新性地將程序與SCADA系統進(jìn)行通訊連接,實(shí)現自動(dòng)化試驗的功能,同時(shí)采用二分法自動(dòng)找點(diǎn)的方式進(jìn)行自動(dòng)交付報告的生成,經(jīng)實(shí)際產(chǎn)品應用已驗證其系統設計的科學(xué)可行性,滿(mǎn)足集中控制自動(dòng)化試驗及交付的目標,具有非常重大的工程意義。

    Abstract:

    The aircraft engine HMU is a key unit in the engine fuel control system. Its main function is to pressurize, meter and servo the fuel according to the input requirements of the engine electronic controller to provide fuel to the engine and ensure that the engine can achieve its best performance. In order to ensure higher efficiency and higher precision testing and delivery of its products during the production process, it is necessary to design an intelligent test system delivery platform to eliminate the impact of human subjective factors on the product. Conducted research on network deployment and technical architecture of the entire system, used hardware and software upgrades and configurations, edited algorithm programs based on LabVIEW software, and innovatively communicated with the SCADA system to realize automated test functions. At the same time, the automatic point-finding method of dichotomy is used to generate automatic delivery reports. The scientific feasibility of the system design has been verified by actual product applications, and it meets the goals of centralized control of automated testing and delivery, which has very significant engineering significance.
