【正文】 攀枝花學(xué)院畢業(yè)設(shè)計（論文） 摘要 I 摘 要 自動布料控制系統(tǒng)主要包括礦倉料位檢測與控制；布料小車位置檢測與控制；以及對相關(guān)設(shè)備實施邏輯連鎖與保護控制，確保整個系統(tǒng)安全、穩(wěn)定、高效的運行。在焦化配料過程中，配煤倉出現(xiàn)混煤對產(chǎn)品質(zhì)量有著直接的影響。目前大多數(shù)焦化廠配煤布料系統(tǒng)中布料方式都是布料工人實現(xiàn)布料，極易造成混煤和堵料斗等質(zhì)量事故。針對傳統(tǒng)的布料形式的弊端，設(shè)計出高效穩(wěn)定的自動布料控制系統(tǒng)顯得尤為的重要。 本自動布料控制系統(tǒng)以煉焦廠煤的自動布料為主體工藝，采用 PLC 為核心處理器，結(jié)合電氣控制技術(shù)、檢測技術(shù)將現(xiàn)場所有控制設(shè)備構(gòu)建為分布式系 統(tǒng)，通過軟件編程和軟硬件組態(tài)技術(shù)實現(xiàn)自動布料的現(xiàn)代化監(jiān)控與管理。開發(fā)出性能優(yōu)良的、適用于各型焦爐的 PLC 控制系統(tǒng)；控制系統(tǒng)包括布料小車位置檢測系統(tǒng)、料倉料位檢測系統(tǒng)、信號的處理及傳輸和布料小車連鎖控制系統(tǒng)。 關(guān)鍵字 料位檢測，可逆皮帶， PLC，電氣控制 攀枝花學(xué)院畢業(yè)設(shè)計（論文） ABSTRACT II ABSTRACT Automatic distributing control system mainly includes the material level in ore bins detection and control。 Cloth car position detection and control。 And the related equipment implementation logic chain control and protection, to ensure the system safe, stable and efficient operation. Appeared in the process of coking ingredients, with coal blended coal has a direct affect the quality of product. Currently most coking plant blending cloth fabric information in the system are workers achieve cloth, cloth is easily mixed coal and quality accidents such as wall hopper. Aimed at the disadvantages of traditional forms of material, design of efficient and stable automatic distributing control system is particularly important. This automatic control system to coking plant coal automatic fabric cloth as the main body craft, USES the PLC as the core processor, bined with electric control technology, detection technology will build field all control equipment for the distributed system, through the software programming and hardware and software configuration technology to realize the modernization of the automatic cloth monitoring and management. Develop excellent performance, suitable for various types of coke oven of PLC control system。 Control system including cloth car position detection system, bin material level detection system, signal processing and transmission and cloth car chain control system. Keywords Material position detection, reversible belt, PLC, electric control 攀枝花學(xué)院畢業(yè)設(shè)計（論文） 目錄 1 目 錄 摘 要 .............................................................................................................................
