【摘要】：液壓扳手泵是液壓扳手緊固螺栓的動(dòng)力源，其輸出壓力的精度直接影響螺栓的聯(lián)接質(zhì)量。目前市場上的液壓板手泵對壓力的控制主要采用溢流閥控制，壓力測量上采用機(jī)械壓力表，誤差較大，控制精度低。為了提高液壓扳手對預(yù)緊及預(yù)緊力的精確控制，本文設(shè)計(jì)了一種基于ARM和Linux操作系統(tǒng)下的液壓扳手泵控制器，并詳細(xì)論述了其設(shè)計(jì)開發(fā)過程。 該控制器采用S3C2440微處理器和Linux嵌入式實(shí)時(shí)操作系統(tǒng)為相應(yīng)的硬件和軟件開發(fā)平臺(tái)，在對某公司一款特定型號(hào)液壓扳手深入研究的基礎(chǔ)上，總結(jié)其在使用過程中出現(xiàn)的問題，并結(jié)合國內(nèi)外發(fā)展現(xiàn)狀設(shè)計(jì)開發(fā)而成。硬件上綜合考慮系統(tǒng)需求、可靠性、接口方便性等因素，為控制器選擇了具體的電子元器件；軟件上針對S3C2440處理器對BootLoader和Linux內(nèi)核做了較為詳細(xì)的分析和移植，，編寫各模塊驅(qū)動(dòng)程序和系統(tǒng)應(yīng)用程序。該控制器系統(tǒng)具有實(shí)時(shí)性強(qiáng)，功能擴(kuò)展容易，系統(tǒng)穩(wěn)定，適應(yīng)環(huán)境能力強(qiáng)等特點(diǎn)。與原有控制器相比，該控制器實(shí)現(xiàn)了液壓扳手的自動(dòng)緊固和拆卸螺栓的功能，采用LCD觸摸屏及圖形用戶界面方便了人機(jī)交互。另外針對壓力控制系統(tǒng)進(jìn)行了詳細(xì)分析，建立了液壓泵系統(tǒng)數(shù)學(xué)模型，確定了PID控制器控制調(diào)節(jié)方法，并設(shè)計(jì)了相應(yīng)的控制程序，確保壓力的精確輸出。 實(shí)驗(yàn)測試表明，該液壓扳手泵控制器達(dá)到了設(shè)計(jì)要求，能夠?qū)崿F(xiàn)自動(dòng)松緊螺栓動(dòng)作及壓力的精確控制。
[Abstract]:The hydraulic wrench pump is the power source of the hydraulic wrench fastening bolt. The precision of the output pressure directly affects the connection quality of the bolt. At present, the pressure control of the hydraulic plate hand pump is mainly controlled by relief valve, and the mechanical pressure gauge is used in the pressure measurement. The error is large and the control precision is low. In order to improve the precise control of preload and preload of hydraulic wrench, a kind of hydraulic wrench pump controller based on ARM and Linux operating system is designed in this paper, and its design and development process is discussed in detail. The controller adopts S3C2440 microprocessor and Linux embedded real-time operating system as the corresponding hardware and software development platform. On the basis of deep research on a specific type of hydraulic wrench in a company, the problems in the process of use are summarized. And combined with the development of domestic and foreign design and development. Considering the system requirement, reliability, interface convenience and other factors in hardware, the specific electronic components are selected for the controller, and the BootLoader and Linux cores are analyzed and transplanted in detail in software for S3C2440 processor. Write each module driver and system application program. The controller system has the characteristics of real-time, easy function expansion, stable system and strong ability to adapt to the environment. Compared with the original controller, the controller can automatically fasten the hydraulic wrench and remove the bolt. The LCD touch screen and the graphical user interface are used to facilitate the man-machine interaction. In addition, the pressure control system is analyzed in detail, the mathematical model of hydraulic pump system is established, the control and regulation method of PID controller is determined, and the corresponding control program is designed to ensure the accurate output of pressure. The experimental results show that the controller of the hydraulic wrench pump meets the design requirements and can realize the precise control of the movement and pressure of the automatic loosening bolt.
