【摘要】：隨著醫(yī)療信息技術(shù)的高速發(fā)展和國(guó)內(nèi)醫(yī)學(xué)影像的快速進(jìn)步,極大地推動(dòng)了醫(yī)療設(shè)備的運(yùn)動(dòng)控制技術(shù)的發(fā)展。嵌入式運(yùn)動(dòng)控制技術(shù)對(duì)實(shí)現(xiàn)醫(yī)療影像設(shè)備網(wǎng)絡(luò)化、系統(tǒng)化、精確化、實(shí)時(shí)化起著至關(guān)重要作用。通過(guò)通訊協(xié)議進(jìn)行數(shù)據(jù)傳輸,實(shí)現(xiàn)電機(jī)各種運(yùn)動(dòng)功能己經(jīng)成為主要的控制方式。因此本文設(shè)計(jì)了基于uC/OS操作系統(tǒng)的運(yùn)動(dòng)控制子系統(tǒng)。首先,本文對(duì)運(yùn)動(dòng)控制系統(tǒng)發(fā)展現(xiàn)狀進(jìn)行了介紹,同時(shí)對(duì)其實(shí)現(xiàn)的意義作了說(shuō)明。然后比較詳細(xì)地對(duì)運(yùn)動(dòng)控制子系統(tǒng)組成原理和主要解決的問(wèn)題進(jìn)行了闡述。其次,介紹了運(yùn)動(dòng)控制子系統(tǒng)的硬件信號(hào)處理部分和軟件通訊部分。此次設(shè)計(jì)主要包括:一方面,基于uC/OS-Ⅱ軟件系統(tǒng)的X射線診斷設(shè)備運(yùn)動(dòng)控制子系統(tǒng)控制板的設(shè)計(jì)與實(shí)現(xiàn)。運(yùn)動(dòng)控制板以C8051F121單片機(jī)為核心控制中心,CPLD作為I/O接口的擴(kuò)展,通過(guò)單片機(jī)內(nèi)部嵌入uC/OS-Ⅱ系統(tǒng),借助外圍電路搭建,對(duì)輸入信息進(jìn)行處理計(jì)算得到輸出結(jié)果,實(shí)現(xiàn)與上位機(jī)進(jìn)行I/O通訊傳輸;同時(shí)通過(guò)控制臺(tái)給出的運(yùn)動(dòng)控制信號(hào),控制X射線診斷設(shè)備床面板電機(jī)橫向與縱向的運(yùn)動(dòng),壓迫器電機(jī)的壓力選擇運(yùn)動(dòng),床體傾斜運(yùn)動(dòng),實(shí)時(shí)采集各運(yùn)動(dòng)位置。另一方面,通過(guò)X射線診斷設(shè)備的限位開(kāi)關(guān)、編碼器等反饋器件,判斷當(dāng)前床體的位置。這里,電機(jī)運(yùn)動(dòng)控制采用變頻器和伺服器通訊協(xié)議方式進(jìn)行控制,實(shí)現(xiàn)上位控制器對(duì)多臺(tái)變頻器、伺服器參數(shù)控制。大大簡(jiǎn)化了硬件設(shè)計(jì)的復(fù)雜程度,降低了電路板板卡的成本并提高了系統(tǒng)的可靠性。由于X射線診斷設(shè)備采用變頻器和伺服器的自身RS485、RS422通訊方式,顯著減少了系統(tǒng)間的連線且具有較高的抗干擾能力。單片機(jī)將采集到的電機(jī)運(yùn)動(dòng)數(shù)據(jù)傳入到上位機(jī)中,完成對(duì)各種運(yùn)動(dòng)控制功能的監(jiān)控,保護(hù)患者的安全,實(shí)現(xiàn)基本的床體運(yùn)動(dòng)故障診斷,并從軟件層面上實(shí)現(xiàn)對(duì)床體運(yùn)動(dòng)的保護(hù)。最后,本文通X射線診斷設(shè)備上對(duì)運(yùn)動(dòng)控制子系統(tǒng)控制板進(jìn)行了實(shí)際調(diào)試,通過(guò)系統(tǒng)EMC測(cè)試后,驗(yàn)證了本文所涉及的運(yùn)動(dòng)控制子系統(tǒng)控制板的可靠性。本文對(duì)完成的實(shí)際工作以及未來(lái)的發(fā)展方向進(jìn)行了概括和總結(jié),同時(shí)也提出了目前系統(tǒng)存在的不足之處以及需要改進(jìn)的方面。
[Abstract]:With the rapid development of medical information technology and the rapid progress of domestic medical image, the movement control technology of medical equipment has been greatly promoted. Embedded motion control technology plays an important role in the realization of medical imaging equipment networking, systematization, accuracy and real-time. Data transmission through communication protocol has become the main control mode to realize all kinds of motor motion functions. Therefore, a motion control subsystem based on UC / OS operating system is designed in this paper. Firstly, this paper introduces the development of motion control system, and explains the significance of its implementation. Then, the principle of motion control subsystem and the main problems are discussed in detail. Secondly, the hardware signal processing part and software communication part of motion control subsystem are introduced. This design mainly includes: on the one hand, the design and implementation of motion control subsystem of X-ray diagnostic equipment based on UC / OS- 鈪，
