自動化是一門涉及學科較多、應用廣泛的綜合性科學技術。作為一個系統(tǒng)工程,它由5個單元組成:
- 程序單元
- 作用單元
- 傳感單元
- 制定單元
- 控制單元
過程自動化:石油煉制和化工等工業(yè)中流體或粉體的化學處理自動化。一般采用由檢測儀表、調(diào)節(jié)器和計算機等組成的過程控制系統(tǒng),對加熱爐、精餾塔等設備或整個工廠進行優(yōu)控制。采用的主要控制方式有反饋控制、前饋控制和優(yōu)控制等。
圖4.自動化設備機械制造自動化:這是機械化、電氣化與自動控制相結合的結果,處理的對象是離散工件。早期的機械制造自動化是采用機械或電氣部件的單機自動化或是簡單的自動生產(chǎn)線。20世紀60年代以后,由于電子計算機的應用,出現(xiàn)了數(shù)控機床、加工中心、機器人、計算機輔助設計、計算機輔助制造、自動化倉庫等。研制出適應多品種、小批量生產(chǎn)型式的柔性制造系統(tǒng)(FMS)。以柔性制造系統(tǒng)為基礎的自動化車間,加上信息管理、生產(chǎn)管理自動化,出現(xiàn)了采用計算機集成制造系統(tǒng)(CIMS)的工廠自動化。
管理自動化:工廠或事業(yè)單位的人、財、物、生產(chǎn)、辦公等業(yè)務管理自動化,是以信息處理為核心的綜合性技術,涉及電子計算機、通信系統(tǒng)與控制等學科。一般采用由多臺具有高速處理大量信息能力的計算機和各種終端組成的局部網(wǎng)絡?,F(xiàn)代已在管理信息系統(tǒng)的基礎上研制出決策支持系統(tǒng)(DSS),為高層管理人員決策提供備選的方案。
對社會的影響自動化是新的技術革命的一個重要方面。自動化技術的研究、應用和推廣,對人類的生產(chǎn)、生活等方式將產(chǎn)生深遠影響。生產(chǎn)過程自動化和辦公室自動化可*地提高社會生產(chǎn)率和工作效率,節(jié)約能源和原材料消耗,保證產(chǎn)品質(zhì)量,改善勞動條件,改進生產(chǎn)工藝和管理體制,加速社會的產(chǎn)業(yè)結構的變革和社會信息化的進程。
