機電一體化技術及其應用研究
1 機電一體化技術發(fā)展
機電一體化是機械、微、控制、機、信息處理等多學科的交叉融合，其發(fā)展和進步有賴于相關技術的進步與發(fā)展，其主要發(fā)展方向有數(shù)字化、智能化、模塊化、化、人性化、微型化、集成化、帶源化和綠色化。
1.1 數(shù)字化
微控制器及其發(fā)展奠定了機電產品數(shù)字化的基礎，如不斷發(fā)展的數(shù)控機床和機器人；而計算機網(wǎng)絡的迅速崛起，為數(shù)字化設計與制造鋪平了道路，如虛擬設計、計算機集成制造等。數(shù)字化要求機電一體化產品的軟件具有高可靠性、易操作性、可維護性、自診斷能力以及友好人機界面。數(shù)字化的實現(xiàn)將便于遠程操作、診斷和修復。
1.2 智能化
即要求機電產品有一定的智能,使它具有類似人的邏輯思考、判斷推理、自主決策等能力。例如在CNC數(shù)控機床上增加人機對話功能，設置智能I/O接口和智能工藝數(shù)據(jù)庫，會給使用、操作和維護帶來極大的方便。隨著模糊控制、神經網(wǎng)絡、灰色、小波理論、混沌與分岔等人工智能技術的進步與發(fā)展，為機電一體化技術發(fā)展開辟了廣闊天地。
1.3 模塊化
由于機電一體化產品種類和生產廠家繁多，研制和開發(fā)具有標準機械接口、動力接口、環(huán)境接口的機電一體化產品單元模塊是一項復雜而有前途的工作。如研制具有集減速、變頻調速電機一體的動力驅動單元；具有視覺、圖像處理、識別和測距等功能的電機一體控制單元等。這樣，在產品開發(fā)設計時，可以利用這些標準模塊化單元迅速開發(fā)出新的產品。
1.4 網(wǎng)絡化
由于網(wǎng)絡的普及，基于網(wǎng)絡的各種遠程控制和監(jiān)視技術方興未艾。而遠程控制的終端設備本身就是機電一體化產品，現(xiàn)場總線和局域網(wǎng)技術使家用電器網(wǎng)絡化成為可能，利用家庭網(wǎng)絡把各種家用電器連接成以計算機為中心的計算機集成家用電器系統(tǒng)，使人們在家里可充分享受各種高技術帶來的好處，因此，機電一體化產品無疑應朝網(wǎng)絡化方向發(fā)展。
1.5 人性化
機電一體化產品的最終使用對象是人，如何給機電一體化產品賦予人的智能、情感和人性顯得愈來愈重要，機電一體化產品除了完善的性能外，還要求在色彩、造型等方面與環(huán)境相協(xié)調，使用這些產品，對人來說還是一種享受，如家用機器人的最高境界就是人機一體化。
1.6 微型化
微型化是精細加工技術發(fā)展的必然，也是提高效率的需要。微機電系統(tǒng)(Micro Electronic Mechanical Systems，簡稱MEMS)是指可批量制作的，集微型機構、微型傳感器、微型執(zhí)行器以及信號處理和控制電路，直至接口、通信和電源等于一體的微型器件或系統(tǒng)。自1986年美國斯坦福大學研制出第一個醫(yī)用微探針，1988年美國加州大學Berkeley分校研制出第一個微電機以來，國內外在MEMS工藝、材料以及微觀機理方面取得了很大進展，開發(fā)出各種MEMS器件和系統(tǒng)，如各種微型傳感器（壓力傳感器、微加速度計、微觸覺傳感器），各種微構件（微膜、微粱、微探針、微連桿、微齒輪、微軸承、微泵、微彈簧以及微機器人等）。
1.7 集成化
集成化既包含各種技術的相互滲透、相互融合和各種產品不同結構的優(yōu)化與復合，又包含在生產過程中同時處理加工、裝配、檢測、管理等多種工序。為了實現(xiàn)多品種、小批量生產的自動化與高效率，應使系統(tǒng)具有更廣泛的柔性。首先可將系統(tǒng)分解為若干層次，使系統(tǒng)功能分散，并使各部分協(xié)調而又安全地運轉，然后再通過軟、硬件將各個層次有機地聯(lián)系起來，使其性能最優(yōu)、功能最強。
1.8 帶源化
是指機電一體化產品自身帶有能源，如太陽能電池、燃料電池和大容量電池。由于在許多場合無法使用電能，因而對于運動的機電一體化產品，自帶動力源具有獨特的好處。帶源化是機電一體化產品的發(fā)展方向之一。
1.9 綠色化
技術的發(fā)展給人們的生活帶來巨大變化，在物質豐富的同時也帶來資源減少、生態(tài)環(huán)境惡化的后果。所以，人們呼喚保護環(huán)境，回歸，實現(xiàn)可持續(xù)發(fā)展，綠色產品概念在這種呼聲中應運而生。綠色產品是指低能耗、低材耗、低污染、舒適、協(xié)調而可再生利用的產品。在其設計、制造、使用和銷毀時應符合環(huán)保和人類健康的要求，機電一體化產品的綠色化主要是指在其使用時不污染生態(tài)環(huán)境，產品壽命結束時，產品可分解和再生利用。
2 機電一體化技術在鋼鐵中應用
在鋼鐵企業(yè)中，機電一體化系統(tǒng)是以微處理機為核心，把微機、工控機、數(shù)據(jù)通訊、顯示裝置、儀表等技術有機的結合起來，采用組裝合并方式，為實現(xiàn)工程大系統(tǒng)的綜合一體化創(chuàng)造有力條件，增強系統(tǒng)控制精度、質量和可靠性。機電一體化技術在鋼鐵企業(yè)中主要應用于以下幾個方面：
2.1 智能化控制技術(IC)
由于鋼鐵具有大型化、高速化和連續(xù)化的特點，傳統(tǒng)的控制技術遇到了難以克服的困難，因此非常有必要采用智能控制技術。智能控制技術主要包括專家系統(tǒng)、模糊控制和神經等，智能控制技術廣泛于鋼鐵的產品設計、生產、控制、設備與產品質量診斷等各個方面，如高爐控制系統(tǒng)、電爐和連鑄車間、軋鋼系統(tǒng)、煉鋼———連鑄———軋鋼綜合調度系統(tǒng)、冷連軋等。
2.2 分布式控制系統(tǒng)(ＤCS)
分布式控制系統(tǒng)采用一臺中央機指揮若干臺面向控制的現(xiàn)場測控計算機和智能控制單元。分布式控制系統(tǒng)可以是兩級的、三級的或更多級的。利用計算機對生產過程進行集中監(jiān)視、操作、管理和分散控制。隨著測控技術的，分布式控制系統(tǒng)的功能越來越多。不僅可以實現(xiàn)生產過程控制，而且還可以實現(xiàn)在線最優(yōu)化、生產過程實時調度、生產計劃統(tǒng)計管理功能，成為一種測、控、管一體化的綜合系統(tǒng)。ＤCS具有特點控制功能多樣化、操作簡便、系統(tǒng)可以擴展、維護方便、可靠性高等特點。ＤCS是監(jiān)視集中控制分散，故障面小，而且系統(tǒng)具有連鎖保護功能，采用了系統(tǒng)故障人工手動控制操作措施，使系統(tǒng)可靠性高。分布式控制系統(tǒng)與集中型控制系統(tǒng)相比，其功能更強，具有更高的安全性。是當前大型機電一體化系統(tǒng)的主要潮流。
2.3 開放式控制系統(tǒng)(OCS)
開放控制系統(tǒng)(Open Control System)是計算機技術發(fā)展所引出的新的結構體系概念?！伴_放”意味著對一種標準的信息交換規(guī)程的共識和支持，按此標準設計的系統(tǒng)，可以實現(xiàn)不同廠家產品的兼容和互換，且資源共享。開放控制系統(tǒng)通過工業(yè)通信網(wǎng)絡使各種控制設備、管理計算機互聯(lián)，實現(xiàn)控制與經營、管理、決策的集成，通過現(xiàn)場總線使現(xiàn)場儀表與控制室的控制設備互聯(lián)，實現(xiàn)測量與控制一體化。
2.4 計算機集成制造系統(tǒng)(CIMS)
鋼鐵企業(yè)的CIMS是將人與生產經營、生產管理以及過程控制連成一體，用以實現(xiàn)從原料進廠，生產加工到產品發(fā)貨的整個生產過程全局和過程一體化控制。目前鋼鐵企業(yè)已基本實現(xiàn)了過程自動化，但這種“自動化孤島”式的單機自動化缺乏信息資源的共享和生產過程的統(tǒng)一管理，難以適應鋼鐵生產的要求。未來鋼鐵企業(yè)競爭的焦點是多品種、小批量生產，質優(yōu)價廉，及時交貨。為了提高生產率、節(jié)能降耗、減少人員及現(xiàn)有庫存，加速資金周轉，實現(xiàn)生產、經營、管理整體優(yōu)化，關鍵就是加強管理，獲取必須的效益，提高了企業(yè)的競爭力。美國、日本等一些大型鋼鐵企業(yè)在20世紀80年代已廣泛實現(xiàn)CIMS化。
2.5 現(xiàn)場總線技術(ＦBT)
現(xiàn)場總線技術(Ｆieｄ Bus Technology)是連接設置在現(xiàn)場的儀表與設置在控制室內的控制設備之間的數(shù)字式、雙向、多站通信鏈路。采用現(xiàn)場總線技術取代現(xiàn)行的信號傳輸技術(如4～20mA，ＤC直流傳輸)就能使更多的信息在智能化現(xiàn)場儀表裝置與更高一級的控制系統(tǒng)之間在共同的通信媒體上進行雙向傳送。通過現(xiàn)場總線連接可省去66%或更多的現(xiàn)場信號連接導線。現(xiàn)場總線的引入導致ＤCS的變革和新一代圍繞開放自動化系統(tǒng)的現(xiàn)場總線化儀表，如智能變送器、智能執(zhí)行器、現(xiàn)場總線化檢測儀表、現(xiàn)場總線化PLC(Programmable Logic Controller)和現(xiàn)場就地控制站等的發(fā)展。
2.6 交流傳動技術
傳動技術在鋼鐵工業(yè)中起作至關重要的作用。隨著電力技術和微電子技術的發(fā)展，交流調速技術的發(fā)展非常迅速。由于交流傳動的優(yōu)越性，電氣傳動技術在不久的將來由交流傳動全面取代直流傳動，數(shù)字技術的發(fā)展，使復雜的矢量控制技術實用化得以實現(xiàn)，交流調速系統(tǒng)的調速性能已達到和超過直流調速水平?，F(xiàn)在無論大容量電機或中小容量電機都可以使用同步電機或異步電機實現(xiàn)可逆平滑調速。交流傳動系統(tǒng)在軋鋼生產中一出現(xiàn)就受到用戶的歡迎，應用不斷擴大。
