論機電一體化的發(fā)展
By integration of machinery development
現(xiàn)代科學(xué)技術(shù)的不斷發(fā)展,極大地推動了不同學(xué)科的交叉與滲透,導(dǎo)致了工程領(lǐng)域的技術(shù)革命與改造,在機械工程領(lǐng)域,由于微電子技術(shù)和計算機技術(shù)的迅速發(fā)展及其向機械工業(yè)的滲透所形成的機電一體化,使機械工業(yè)的技術(shù)結(jié)構(gòu)、產(chǎn)品機構(gòu)、功能與構(gòu)成、生產(chǎn)方式及管理體系發(fā)生了巨大變化,使工業(yè)生產(chǎn)由“機械電氣化”邁入了“機電一體化”為特征的發(fā)展階段。
The modern science and technology unceasing development, impelled different discipline intersecting enormously with the seepage, has caused the project domain technological revolution and the transformation, in mechanical engineering domain, because the microelectronic technology and the computer technology rapid development and forms to the mechanical industry seepage the integration of machinery, caused the mechanical industry the technical structure, the product organization, the function and the constitution, the production method and the management system has had the huge change, caused the industrial production to enter into “the integration of machinery” by “the machinery electrification” for the characteristic development phase.
一、 機電一體化概要
First, the integration of machinery outline
機電一體化是指在機構(gòu)得主功能、動力功能、信息處理功能和控制功能上引進(jìn)電子技術(shù),將機械裝置與電子化設(shè)計及軟件結(jié)合起來所構(gòu)成的系統(tǒng)的總稱。
Integration of machinery is refers in the organization new owner function, the power function, in the information processing function and the control function introduces the electronic technology, unifies the system the mechanism and the computerization design and the software which constitutes always to call.
機電一體化發(fā)展至今也已成為一門有著自身體系的新型學(xué)科,隨著科學(xué)技術(shù)的不但發(fā)展,還將被賦予新的內(nèi)容,但其基本特征可概括為:機電一體化是從系統(tǒng)的觀點出發(fā),綜合運用機械技術(shù)、微電子技術(shù)、自動控制技術(shù)、計算機技術(shù)、信息技術(shù)、傳感測控技術(shù)、電力電子技術(shù)、接口技術(shù)、信息變換技術(shù)以及軟件編程技術(shù)等群體技術(shù),根據(jù)系統(tǒng)功能目標(biāo)和優(yōu)化組織目標(biāo),合理配置與布局各功能單元,在多功能、高質(zhì)量、高可靠性、低能耗的意義上實現(xiàn)特定功能價值,并使整個系統(tǒng)最優(yōu)化的系統(tǒng)工程技術(shù),由此而產(chǎn)生的功能系統(tǒng),則成為一個機電一體化系統(tǒng)或機電一體化產(chǎn)品。
The integration of machinery development also has become one to have until now own system new discipline, not only develops along with the science and technology, but also entrusts with the new content, but its basic characteristic may summarize is: The integration of machinery is embarks from the system viewpoint, synthesis community technologies and so on utilization mechanical technology, microelectronic technology, automatic control technology, computer technology, information technology, sensing observation and control technology, electric power electronic technology, connection technology, information conversion technology as well as software programming technology, according to the system function goal and the optimized organization goal, reasonable disposition and the layout various functions unit, in multi-purpose, high grade, redundant reliable, in the low energy consumption significance realize the specific function value, and causes the overall system optimization the systems engineering technology, from this produces function system, then becomes an integration of machinery systematic or the integration of machinery product.
因此,“機電一體化”涵蓋“技術(shù)”和“產(chǎn)品”兩個方面,只是,機電一體化技術(shù)是基于上述群體技術(shù)有機融合的一種綜合技術(shù),而不是機械技術(shù)、微電子技術(shù)以及其它新技術(shù)的簡單組合、拼湊。這是機電一體化與機械加電氣所形成的機械電氣化在概念上的根本區(qū)別,機械工程技術(shù)有純技術(shù)發(fā)展到機械電氣化,仍屬傳統(tǒng)機械,其主要功能依然是代替和放大的體力,但是發(fā)展到機電一體化后,其中的微電子裝置除可取代某些機械部件的原有功能外,還能賦予許多新的功能,如自動檢測、自動處理信息、自動顯示記錄、自動調(diào)節(jié)與控制自動診斷與保護(hù)等,即機電一體化產(chǎn)品不僅是人的手與肢體的延伸,還是人的感官與頭腦的眼神,具
有智能化的特征是機電一體化與機械電氣化在功能上的本質(zhì)區(qū)別。
Therefore, “the integration of machinery” covering “the technology” and “the product” two aspects, only are, the integration of machinery technology is based on the above community technology organic fusion one kind of comprehensive technology, but is not mechanical technical, the microelectronic technology as well as other new technical simple combination, pieces together, this is the integration of machinery and the machinery adds the machinery electrification which the electricity forms in the concept basic difference, the mechanical engineering technology has the merely technical to develop the machinery electrification, still was the traditional machinery, its main function still was replaces with the enlargement physical strength, after but developed the integration of machinery, micro electron installment eliminated may substitute for certain mechanical parts original Outside function, but also can entrust with many new functions, like the automatic detection, the automatic reduction information, demonstrate the record, the automatic control and the control automatic diagnosis and the protection automatically and so on, not only namely the integration of machinery product is human's hand and body extending, human's sense organ and the brains look, has the intellectualized characteristic is the integration of machinery and the machinery electrification distinguishes in the function essence.
二、機電一體化的發(fā)展?fàn)顩r
Second, the integration of machinery development condition
機電一體化的發(fā)展大體可以分為3個階段,20世紀(jì)60年代以前為第一階段,這一階段稱為初級階段,在這一時期,人們自覺不自覺地利用電子技術(shù)的初步成果來完善機械產(chǎn)品的性能。特別是在第二次世界大戰(zhàn)期間,戰(zhàn)爭刺激了機械產(chǎn)品與電子技術(shù)的結(jié)合,這些機電結(jié)合的軍用技術(shù),戰(zhàn)后轉(zhuǎn)為民用,對戰(zhàn)后經(jīng)濟的恢復(fù)起了積極的作用,那時研制和開發(fā)從總體上看還處于自發(fā)狀態(tài),由于當(dāng)時電子技術(shù)的發(fā)展尚未達(dá)到一定水平,機械技術(shù)與電子技術(shù)的結(jié)合還不可能廣泛和深入發(fā)展,已經(jīng)開發(fā)的產(chǎn)品也無法大量推廣。
Integration of machinery development may divide into 3 stages roughly, 20th century 60's before for the first stage, this stage is called the initial stage, in this time, the people determination not on own initiative uses the electronic technology the preliminary achievement to consummate the mechanical product the performance, specially in Second World War period, the war has stimulated the mechanical product and the electronic technology union, these mechanical and electrical union military technology, postwar transfers civilly, to the postwar economical restoration positive function, has developed and the development at that time generally speaking also is at the spontaneous condition, because at that time the electronic technology development not yet achieved certainly Level. Mechanical technical and electronic technology union also not impossible widespread and thorough development, already developed the product was also unable to promote massively.
20世紀(jì)70~80年代為第二階段,可稱為蓬勃發(fā)展階段。這一時期,計算機技術(shù)、控制技術(shù)、通信技術(shù)的發(fā)展,為機電一體化的發(fā)展奠定了技術(shù)基礎(chǔ)。大規(guī)模、超大規(guī)模集成電路和微型計算機的迅猛發(fā)展,為機電一體化的發(fā)展提供了充分的物質(zhì)基礎(chǔ)。這個時期的特點是:①Mechatronics一詞首先在日本被普遍接受,大約到20世紀(jì)80年代末期在世界范圍內(nèi)得到比較廣泛的承認(rèn);②機電一體化技術(shù)和產(chǎn)品得到了極大發(fā)展;③各國均開始對機電一體化技術(shù)和產(chǎn)品給以很大的關(guān)注和支持。
The 20th century 70~80 ages for the second stage, may be called the vigorous development stage, this time, the computer technology, the control technology, the communication development, has laid the technology base for the integration of machinery development, large-scale, ultra large scale integrated circuit and microcomputer swift and violent development, has provided the full material base for the integration of machinery development, this time characteristic is:①A mechatronics word first generally is accepted in Japan, probably obtains the quite widespread acknowledgment to 1980s last stages in the worldwide scale;②The integration of machinery technology and the product obtained the enormous development;③The various countries start to the integration of machinery technology and the product give the very big attention and the support.
20世紀(jì)90年代后期,開始了機電一體化技術(shù)向智能化方向邁進(jìn)的新階段,機電一體化進(jìn)入深入發(fā)展時期。一方面,光學(xué)、通信技術(shù)等進(jìn)入了機電一體化,微細(xì)加工技術(shù)也在機電一體化中嶄露頭腳,出現(xiàn)了光機電一體化和微機電一體化等新分支;另一方面對機電一體化系統(tǒng)的建模設(shè)計、分析和集成方法,機電一體化的學(xué)科體系和發(fā)展趨勢都進(jìn)行了深入研究。同時,由于人工智能技術(shù)、神經(jīng)網(wǎng)絡(luò)技術(shù)及光纖技術(shù)等領(lǐng)域取得的巨大進(jìn)步,為機電一體化技術(shù)開辟了發(fā)展的廣闊天地。這些研究,將促使機電一體化進(jìn)一步建立完整的基礎(chǔ)和逐漸形成完整的科學(xué)體系。
1990s later periods, started the integration of machinery technology the new stage which makes great strides forward to the intellectualized direction, the integration of machinery enters the thorough development time, on the one hand, optics, the communication and so on entered the integration of machinery, processes the technology also zhan to appear tiny in the integration of machinery the foot, appeared the light integration of machinery and the micro integration of machinery and so on the new branch; On the other hand to the integration of machinery system modelling design, the analysis and the integrated method, the integration of machinery discipline system and the trend of development has all conducted the thorough research, simultaneously, because domains and so on artificial intelligence technology, neural network technology and optical fiber technology obtain the huge progress, opened the development vast world for the integration of machinery technology, these research, will urge the integration of machinery further to establish the integrity the foundation and forms the integrity gradually the scientific system.
三、機電一體化的發(fā)展趨勢
Third, the integration of machinery trend of development
機電一體化是集機械、電子、光學(xué)、控制、計算機、信息等多學(xué)科的交叉綜合,它的發(fā)展和進(jìn)步依賴并促進(jìn)相關(guān)技術(shù)的發(fā)展和進(jìn)步。因此,機電一體化的主要發(fā)展方向如下:
Integration of machinery is the collection machinery, the electron, optics, the control, the computer, the information and so on the multi-disciplinary overlapping syntheses, its development and the progress rely on and promote the correlation technology development and the progress, therefore, the integration of machinery main development direction is as follows:
3.1智能化
3.1Intellectualized
智能化是21世紀(jì)機電一體化技術(shù)發(fā)展的一個重要發(fā)展方向。人工智能在機電一體化建設(shè)者的研究日益得到重視,機器人與數(shù)控機床的智能化就是重要應(yīng)用。這里所說的“智能化”是對機器行為的描述,是在控制理論的基礎(chǔ)上,吸收人工智能、運籌學(xué)、計算機科學(xué)、模糊數(shù)學(xué)、心理學(xué)、生理學(xué)和混沌動力學(xué)等新思想、新方法,模擬人類智能,使它具有判斷推理、邏輯思維、自主決策等能力,以求得到更高的控制目標(biāo)。誠然,使機電一體化產(chǎn)品具有與人完全相同的智能,是不可能的,也是不必要的。但是,高性能、高速的微處理器使機電一體化產(chǎn)品賦有低級智能或人的部分智能,則是完全可能而又必要的。
Intellectualization is a 21st century integration of machinery technological development important development direction, the artificial intelligence obtains day by day in the integration of machinery constructor's research takes, the robot and the numerical control engine bed intellectualization is the important application, here said “the intellectualization” is to the machine behavior description, is in the control theory foundation, the absorption artificial intelligence, the operations research, the computer science, the fuzzy mathematics, the psychology, the physiology and the chaos dynamics and so on the new thought, the new method, simulate the human intelligence, enable it to have abilities and so on judgment inference, logical thinking, independent decision-making, obtains the higher control goal in order to, indeed, enable the integration of machinery product to have With the human identical intelligence, is not impossible, also is nonessential, but, the high performance, the high speed microprocessor enable the integration of machinery product to have preliminary intelligent or human's partial intelligences, then is completely possible and essential.
3.2模塊化
3.2 Modular
模塊化是一項重要而艱巨的工程。由于機電一體化產(chǎn)品種類和生產(chǎn)廠家繁多,研制和開發(fā)具有標(biāo)準(zhǔn)機械接口、電氣接口、動力接口、環(huán)境接口的機電一體化產(chǎn)品單元是一項十分復(fù)雜但又是非常重要的事。如研制集減速、智能調(diào)速、電機于一體的動力單元,具有視覺、圖像處理、識別和測距等功能的控制單元,以及各種能完成典型操作的機械裝置。這樣,可利用標(biāo)準(zhǔn)單元迅速開發(fā)出新產(chǎn)品,同時也可以擴大生產(chǎn)規(guī)模。這需要制定各項標(biāo)準(zhǔn),以便各部件、單元的匹配和接口。由于利益沖突,近期很難制定國際或國內(nèi)這方面的標(biāo)準(zhǔn),但可以通過組建一些大企業(yè)逐漸形成。顯然,從電氣產(chǎn)品的標(biāo)準(zhǔn)化、系列化帶來的好處可以肯定,無論是對生產(chǎn)標(biāo)準(zhǔn)機電一體化單元的企業(yè)還是對生產(chǎn)機電一體化產(chǎn)品的企業(yè),規(guī)?;瘜⒔o機電一體化企業(yè)帶來美好的前程。
Modulations are one item important and the arduous project, because the integration of machinery product type and the manufacturer are many, but the development and the development have standard mechanical connection, electrical connection, power connection, the environment connection integration of machinery product unit are an item extremely complex also are the extremely important matters, like the development collection deceleration, the intelligent velocity modulation, the electrical machinery in a body power unit, have function and so on vision, imagery processing, recognition and range finder control units, as well as each kind can complete the model operation the mechanism, like this, may use the standard unit to develop the new product rapidly, simultaneously also may expand the scale of production, this need formulation Each standard, in order to various parts, the unit match and the connection, as a result of the conflicts of interest, very will be difficult to formulate international or the domestic this aspect standard in the near future, but might through set up some big enterprises to form gradually, obviously, the advantage which from the electrical product standardization, the seriation will bring may affirm, regardless of will be to produces the standard integration of machinery unit the enterprise to produce the integration of machinery product the enterprise, the formalization will give the integration of machinery enterprise to bring the happy future.
3.3網(wǎng)絡(luò)化
3.3 Network
20世紀(jì)90年代,計算機技術(shù)等的突出成就是網(wǎng)絡(luò)技術(shù)。網(wǎng)絡(luò)技術(shù)的興起和飛速發(fā)展給科學(xué)技術(shù)、工業(yè)生產(chǎn)、政治、軍事、教育義舉人么日常生活都帶來了巨大的變革。各種網(wǎng)絡(luò)將全球經(jīng)濟、生產(chǎn)連成一片,企業(yè)間的競爭也將全球化。機電一體化新產(chǎn)品一旦研制出來,只要其功能獨到,質(zhì)量可靠,很快就會暢銷全球。由于網(wǎng)絡(luò)的普及,基于網(wǎng)絡(luò)的各種遠(yuǎn)程控制和監(jiān)視技術(shù)方興未艾,而遠(yuǎn)程控制的終端設(shè)備本身就是機電一體化產(chǎn)品。現(xiàn)場總線和局域網(wǎng)技術(shù)是家用電器網(wǎng)絡(luò)化已成大勢,利用家庭網(wǎng)絡(luò)將各種家用電器連接成以計算機為中心的計算機集成家電系統(tǒng),使人們在家里分享各種高技術(shù)帶來的便利與快樂。因此,機電一體化產(chǎn)品無疑朝著網(wǎng)絡(luò)化方向發(fā)展。
1990s, the computer technology and so on the prominent achievement was the networking, networking starting with the rapid development for the science and technology, the industrial production, political, the military, the education magnanimous act person daily life has all brought the huge transformation, each kind of network the global economy, the production linked up into a single stretch, enterprise's competition will also globalize, once the integration of machinery new product developed, so long as its function were original, the quality was reliable, very quick could the best-selling whole world, as a result of the network popularization, was on the rise based on network each kind of long-distance control and the surveillance technology, but long-distance control terminal device itself will be the integration of machinery product, the field busWas the domestic electric appliances network has become the situation with the local area network technology, connected using the family network each kind of domestic electric appliances take the computer as the central computer integration electrical appliances system, caused the people at home to share the inconvenience and the joy which each kind of high-tech brought, therefore, the integration of machinery product faced the network direction to develop without doubt.
3.4微型化
3.4 Microminiaturized
微型化興起于20世紀(jì)80年代末,指的是機電一體化向微型機器和微觀領(lǐng)域發(fā)展的趨勢。國外稱其為微電子機械系統(tǒng)(MEMS),泛指幾何尺寸不超過1cm3的機電一體化產(chǎn)品,并向微米、納米級發(fā)展。微機電一體化產(chǎn)品體積小 、耗能少、運動靈活,在生物醫(yī)療、軍事、信息等方面具有不可比擬的優(yōu)勢。微機電一體化發(fā)展的瓶頸在于微機械技術(shù),微機電一體化產(chǎn)品的加工采用精細(xì)加工技術(shù),即超精密技術(shù),它包括光刻技術(shù)和蝕刻技術(shù)兩類。
Microminiaturization emerge in the end of 1980s, refers is the integration of machinery to the miniature machine and the microscopic domain development tendency, overseas name it micro electron mechanical system (MEMS), makes a general reference the geometry size not to surpass 1cm3 the integration of machinery product, and to micron, the nanometer level development, the micro integration of machinery product volume small, consumes energy few, the movement is nimble, in aspects and so on biological medical service, military, information has the incomparable superiority, the micro integration of machinery development bottleneck lies in the micro mechanical technology, the micro integration of machinery product processing uses the fine processing technology, namely ultra precise technology, it including photoetching technology and etching technology two kinds.
3.5綠色化
3.5 Green
工業(yè)的發(fā)達(dá)給人們生活帶來了巨大變化。一方面,物質(zhì)豐富,生活舒適;另一方面,資源減少,生態(tài)環(huán)境受到嚴(yán)重污染。于是,人們呼吁保護(hù)環(huán)境資源,回歸自然。綠色產(chǎn)品概念在這種呼聲下應(yīng)運而生,綠色化是時代的趨勢。綠色產(chǎn)品在其設(shè)計、制造、使用和銷毀的生命過程中,符合特定的環(huán)境保護(hù)和人類健康的要求,對生態(tài)環(huán)境無害或危害極少,資源利用率極高。設(shè)計綠色的機電一體化產(chǎn)品,具有遠(yuǎn)大的發(fā)展前途。機電一體化產(chǎn)品的綠色化主要是指,使用時不污染生態(tài)環(huán)境,報廢后能回收利用。
Industries lived developed for the people have brought the huge change, on the one hand, the material was rich, the life was comfortable; On the other hand, the resources reduce, the ecological environment receives the serious pollution, therefore, the people appealed the protection environment resources, the return nature, the green product concept arises at the historic moment under this kind of call, the green is the time tendency, the green product in its design, the manufacture, the use and in the destruction life process, conforms to the specific environmental protection and the human health request, harmless or the harm are extremely few to the ecological environment, the resources use factor is extremely high, the design green integration of machinery product, has the broad development future, the integration of machinery product green mainly is refers, when use does not pollute the ecological environment, after the abandonment can recycle the use.
3.6系統(tǒng)化
3.6 systematizations
系統(tǒng)化的表現(xiàn)特征之一就是系統(tǒng)體系結(jié)構(gòu)進(jìn)一步采用開放式和模式化的總線結(jié)構(gòu)。系統(tǒng)可以靈活組態(tài),進(jìn)行任意剪裁和組合,同時尋求實現(xiàn)多子系統(tǒng)協(xié)調(diào)控制和綜合管理。表現(xiàn)之二是通信功能的大大加強,一般除RS232外,還有RS485、DCS人格化。未來的機電一體化更加注重產(chǎn)品與人的關(guān)系,機電一體化的人格化有兩層含義。一層是,機電一體化產(chǎn)品的最終使用對象是人,如何賦予機電一體化產(chǎn)品人的智能、情感、人性顯得越來越重要,特別是對家用機器人,其高層境界就是人機一體化。另一層是模仿生物機理,研制各種機電一體花產(chǎn)品。事實上,許多機電一體化產(chǎn)品都是受動物的啟發(fā)研制出來的
One of systematized performance characteristics is the system architecture further uses open style and the patternizing main line structure. the system may the nimble configuration, carries on tailors and the combination willfully, simultaneously seeks realizes the multi-subsystem coordination control and the synthesis management, second performance is the correspondence function big enhancement, generally besides RS232, but also will have RS485, the DCS personification, the future integration of machinery even more pays great attention to the product and human's relations, the integration of machinery personification will have two meanings, one will be, the integration of machinery product finally user will be a human, how will entrust with the integration of machinery product person's intelligence, the emotion, the human nature appears more and more importantly, specially the opposite partyWith the robot, its high-level boundary is the man-machine integration, another imitates the biological mechanism, develops each kind of mechanical and electrical body flower product, in fact, many integration of machinery products all are developed animal's inspiration.
四、典型的機電一體化產(chǎn)品
Fourth, the model integration of machinery product
機電一體化產(chǎn)品分系統(tǒng)(整機)和基礎(chǔ)元、部件兩大類。典型的機電一體化系統(tǒng)有:數(shù)控機床、機器人、汽車電子化產(chǎn)品、智能化儀器儀表、電子排版印刷系統(tǒng)、CAD/CAM系統(tǒng)等。典型的機電一體化元、部件有:電力電子器件及裝置、可編程序控制器、模糊控制器、微型電機、傳感器、專用集成電路、伺服機構(gòu)等。這些典型的機電一體化產(chǎn)品的技術(shù)現(xiàn)狀、發(fā)展趨勢、市場前景分析從略。

五、我國發(fā)展“機電一體化”面臨的形勢和任務(wù)
Fifth, our country develops the situation and the duty integration of machinery work which “
機電一體化工作主要包括兩個層次:一是用微電子技術(shù)改造傳統(tǒng)產(chǎn)業(yè),其目的是節(jié)能、節(jié)材,提高工效,提高產(chǎn)品質(zhì)量,把傳統(tǒng)工業(yè)的技術(shù)進(jìn)步提高一步;二是開發(fā)自動化、數(shù)字化、智能化機電產(chǎn)品,促進(jìn)產(chǎn)品的更新?lián)Q代。
The integration of machinery” faces mainly includes two levels: One, with the microelectronic technology transformation tradition industry, its goal is the energy conservation, the nodal wood, enhances the work efficiency, improves the product quality, enhances the traditional industry technology advancement one step; Two, development automation, digitization, intellectualized mechanical and electrical products, promotion product renewal.
(一)我國“機電一體化”工作面臨的形勢
(1) our country “the integration of machinery” the work faces situation
1. 我國用微電子技術(shù)改造傳統(tǒng)工業(yè)的工作量大而廣,有難度
1. Our country is big with the microelectronic technology transformation tradition industry work load and is broad, has difficulty
2. 我國用機電一體化技術(shù)加速產(chǎn)品更新?lián)Q代,提高市場占有率的呼聲高,有壓力。
2. Our country with the integration of machinery technology acceleration product renewal, enhances the market share the call to be high, has the pressure.
3. 我國用機電一體化產(chǎn)品取代技術(shù)含量和附加值低,耗能、耗水、耗材高,污染、擾民產(chǎn)品的責(zé)任重,有意義。在我國工業(yè)系統(tǒng)中,能耗、耗水大戶,對環(huán)境污染嚴(yán)重的企業(yè)還占相當(dāng)大的比重。近年來我國的工業(yè)結(jié)構(gòu)、產(chǎn)品結(jié)構(gòu)雖然幾經(jīng)調(diào)整,但由于多種原因,成效一直不夠明顯。這里面固然有上級領(lǐng)導(dǎo)部門的政出多門問題,有企業(yè)的“故土難離”“死守故業(yè)”問題,但不可否認(rèn)也有優(yōu)化不出理想的產(chǎn)業(yè),優(yōu)選不出中意的產(chǎn)品問題。上佳的答案早就擺在了這些企業(yè)的面前,這就是發(fā)展機電一體化,開發(fā)和生產(chǎn)有
