【摘要】：電磁攪拌技術(shù)是對金屬凝固過程進(jìn)行精確控制的一種有效手段，是獲得高品質(zhì)金屬材料的重要環(huán)節(jié)。隨著計算機(jī)和互聯(lián)網(wǎng)的發(fā)展，用于電磁攪拌器的控制系統(tǒng)也迅速發(fā)展起來。利用現(xiàn)代微電子技術(shù)，電力電子技術(shù)和計算機(jī)技術(shù)的新成果，電磁攪拌器控制系統(tǒng)進(jìn)一步提高鋼材質(zhì)量。但是，傳統(tǒng)的電磁攪拌器控制系統(tǒng)一般運行在Linux系統(tǒng)或Windows系統(tǒng)之上，不僅需要昂貴的工控機(jī)，還需要額外的數(shù)據(jù)采集電路支持，成本高，通用性、靈活性差。因此，需要一種創(chuàng)新的控制系統(tǒng)來解決電磁攪拌器控制系統(tǒng)成本高、通用性和靈活性差的缺點。 把傳統(tǒng)的電磁攪拌器控制系統(tǒng)移植到基于ARM芯片的嵌入式板卡中，不僅能夠降低硬件成本，，而且可以擺脫對外圍數(shù)據(jù)采集電路的依賴，使用ARM自帶的GPIO端口完成數(shù)據(jù)采集工作，大大減少了硬件布置的復(fù)雜性。同時，采用UI與邏輯分離的設(shè)計方案，降低界面與控制邏輯的耦合度，使用戶可以按照自己的需求定制界面，同時不需要對底層邏輯進(jìn)行修改，大大提高了系統(tǒng)的通用性。在對已有的電磁攪拌器控制系統(tǒng)進(jìn)行進(jìn)一步的需求分析后，對嵌入式電磁攪拌器控制系統(tǒng)軟件的設(shè)計進(jìn)行了重構(gòu)，在開發(fā)板的基礎(chǔ)上你自行設(shè)計了專用的嵌入式電磁攪拌器控制板，并通過硬件調(diào)試，最終完成了整個系統(tǒng)的開發(fā)和測試工作，已交付用戶使用。 通過該項目的開發(fā)，證明了把電磁攪拌器控制系統(tǒng)移植到基于ARM的嵌入式板卡中的可能性。同時，作為國內(nèi)首個嵌入式電磁攪拌器控制系統(tǒng)，該系統(tǒng)的出現(xiàn)必將對國內(nèi)電磁攪拌器控制系統(tǒng)的發(fā)展產(chǎn)生深遠(yuǎn)影響。
[Abstract]:Electromagnetic stirring technology is an effective means to accurately control the solidification process of metals and an important link to obtain high quality metal materials. With the development of computer and Internet, the control system for electromagnetic agitator has developed rapidly. Taking advantage of the new achievements of modern microelectronic technology, power electronics technology and computer technology, the control system of electromagnetic stirrer can further improve the quality of steel. However, the traditional electromagnetic agitator control system generally runs on the Linux system or the Windows system. It not only needs expensive industrial control computer, but also needs additional data acquisition circuit support, high cost, universal and poor flexibility. Therefore, an innovative control system is needed to solve the disadvantages of high cost, low versatility and flexibility of electromagnetic stirrer control system. Transplanting the traditional electromagnetic agitator control system to the embedded board based on ARM chip can not only reduce the cost of hardware, but also get rid of the dependence on peripheral data acquisition circuit, and complete the data acquisition by using the GPIO port of ARM. The complexity of hardware layout is greatly reduced. At the same time, using the design scheme of separating UI and logic, the coupling degree between interface and control logic is reduced, and the user can customize the interface according to his own needs, and at the same time, the underlying logic is not modified, which greatly improves the generality of the system. After the further requirement analysis of the existing electromagnetic stirrer control system, the software design of the embedded electromagnetic stirrer control system is reconstructed. On the basis of the development board, you have designed a special embedded electromagnetic stirrer control board, and through hardware debugging, you have finally completed the development and testing of the whole system, which has been delivered to the user. Through the development of this project, the possibility of transplanting the electromagnetic agitator control system to the embedded board based on ARM is proved. At the same time, as the first embedded electromagnetic stirrer control system in China, the emergence of the system will have a profound impact on the development of domestic electromagnetic stirrer control system.
