【正文】 ntages of cheap prices bined controller hardware is standard and overall. According to the practical application of target software in order to control the content of the user procedures memory controller, the controller and connecting the accused convenient target. In the mid1970s, the Plc has been widely used as a central processing unit microprocessor, import export module and the external circuits are used, largescale integrated circuits even when the Plc is no longer the only logical (IC) judgment functions also have data processing, PID conditioning and data munications functions. International Electro technical Commission (IEC) standards promulgated programmable controller for programmable controller draft made the following definition: programmable controller is a digital electronic puters operating system, specifically for applications in the industrial design environment. It used programmable memory, used to implement logic in their internal storage operations, sequence control, timing, counting and arithmetic operations, such as operating instructions, and through digital and analog input and output, the control of various types of machinery or production processes. Programmable controller and related peripherals, and industrial control systems easily linked to form a whole, to expand its functional design. Programmable controller for the user, is a noncontact equipment, the procedures can be changed to change production processes. The programmable controller has bee a powerful tool for factory automation, widely popular replication. Programmable controller is useroriented industries dedicated control puter, with many distinctive features. First, high reliability, antiinterference capability。 Second programming visual, simple。 Third, adaptability good。 functional improvements, strong functional interface.It is new type industry control equipment which is developed based on microprocessor and integrated with puter technology, automation technology and munication technology. This paper studied the specific application thoroughly of PLC in Automation Three Dimensional Warehouse Control System based on the execution of Tianjin Harvest Automation Three Dimensional Warehouse Control System 2003.With the development of puter information technology, increasingly expanding of modern enterprise production scale and more and more fierce market petition, new requirements of enterprise logistics by market are emerging, and automated highrise warehouses gains more attention and have been used widely, SRM is the most important conveying and lifting equipment in automated highrise warehouse.This paper introduced the application of S7200 PLC produced by SIEMENS pany in stackers used for automatic stereoscopic warehouse. All the new technologies such as data in put by BCD dialing board, light and electricity checking, variable frequency and variable speed, step driving are incorporated in a proportionally reduced model for stereoscopic warehouse. The model can simulate real stereoscopic warehouse well..It has a lot of merits .Such as strong holding capacity、highly reliability、assignment flexibility、piling program easily、used expediently and expansion easily .At present ,PLC bees the most important in industrialization realm and the most application control device .It is the first place in the three supports of the industrial automated production (PLC、Industrial robot、Computeraided design and manufacture ). It is trend of the times of the world to use PLC and PLC will be used speedily overall in our country.With the produce scale of modernization business is more and more expander and deeper, warehouse is more important and indispensable in producing procedure system. Stereoscopic warehouse which takes smallest are and the best utilization ratio in space instead of plane warehouse. this can improve the level of the warehouse procedure. It needs to use Solid Automated Warehouse (SAW) which is made of puter control technology to be full of modernization produce and circulate .SAW is the main equipment in the modern circulate system and not only one of CIMS integrated link but also strong status in FMS and FAS .附 錄B 中英文對(duì)照自動(dòng)化立體倉(cāng)庫(kù)簡(jiǎn)介　　自動(dòng)化立體倉(cāng)庫(kù)是現(xiàn)代物流系統(tǒng)中迅速發(fā)展的一個(gè)重要組成部分，它具有節(jié)約用地、減輕勞動(dòng)強(qiáng)度、消除差錯(cuò)、提高倉(cāng)儲(chǔ)自動(dòng)化水平及管理水平、提高管理和操作人員素質(zhì)、降低儲(chǔ)運(yùn)損耗、有效地減少流動(dòng)資金的積壓、提高物流效率等諸多優(yōu)點(diǎn)。與廠級(jí)計(jì)算機(jī)管理信息系統(tǒng)聯(lián)網(wǎng)以及與生產(chǎn)線(xiàn)緊密相連的自動(dòng)化立體倉(cāng)庫(kù)更是當(dāng)今CIMS(計(jì)算機(jī)集成制造系統(tǒng))及FMS(柔性制造系統(tǒng))必不可少的關(guān)鍵環(huán)節(jié)。　　自動(dòng)化所圍繞自動(dòng)化倉(cāng)儲(chǔ)系統(tǒng)開(kāi)發(fā)了多種自動(dòng)化系統(tǒng)硬件設(shè)備及軟件產(chǎn)品， 如: 不同類(lèi)型的庫(kù)存管理軟件、系統(tǒng)仿真軟件、圖形監(jiān)控及調(diào)度軟件、堆垛機(jī)輸送機(jī)控制軟件、條形碼識(shí)別跟蹤系統(tǒng)、搬運(yùn)機(jī)器人、碼垛機(jī)械手、自動(dòng)運(yùn)行小車(chē)、貨物分選系統(tǒng)、堆垛機(jī)認(rèn)址檢測(cè)系統(tǒng)、堆垛機(jī)控制系統(tǒng)、貨位探測(cè)器、高度檢測(cè)器、輸送系統(tǒng)、碼垛系統(tǒng)、自動(dòng)輸送小車(chē)等產(chǎn)品。 主要技術(shù)性能(1) 控制系統(tǒng)：　　技術(shù)先進(jìn)，采用現(xiàn)場(chǎng)控制總線(xiàn)直接通訊的方式，真正做到計(jì)算機(jī)只監(jiān)不控，所有的決策、作業(yè)調(diào)度和現(xiàn)場(chǎng)信息等均由堆垛機(jī)、出入庫(kù)輸送機(jī)等現(xiàn)場(chǎng)設(shè)備通過(guò)相互間的通訊來(lái)協(xié)調(diào)完成?！　?每個(gè)貨位的托盤(pán)號(hào)分別記錄在堆垛機(jī)和計(jì)算機(jī)的數(shù)據(jù)庫(kù)里，管理員可利用對(duì)比功能來(lái)比較計(jì)算機(jī)的記錄和堆垛機(jī)里的記錄，并進(jìn)行修改，修改可自動(dòng)完成和手動(dòng)完成?！　?系統(tǒng)軟、硬件功能齊全，用戶(hù)界面清晰，便于操作維護(hù)?！　?堆垛機(jī)有自動(dòng)召回原點(diǎn)的功能，即無(wú)論任何情況，只要貨叉居中且水平運(yùn)行正常時(shí)，可按照下達(dá)的命令自動(dòng)返回原點(diǎn)。這意味著操作人員和維護(hù)人員可以盡量不進(jìn)入巷道?！　?智能的控制系統(tǒng)，可以實(shí)現(xiàn)真正的自動(dòng)盤(pán)庫(kù)功能，避免了以往繁重的人工盤(pán)庫(kù)工作，減輕了倉(cāng)庫(kù)管理人員的工作強(qiáng)度，同時(shí)保證了出庫(kù)作業(yè)的出錯(cuò)率為零。(2) 監(jiān)控管理系統(tǒng)包括數(shù)據(jù)管理、入庫(kù)管理、出庫(kù)管理、查詢(xún)、報(bào)表、單據(jù)與盤(pán)庫(kù)、報(bào)警、監(jiān)控與動(dòng)畫(huà)等模塊。 可編程控制器是60年代末在美國(guó)首先出現(xiàn)的，當(dāng)時(shí)叫可編程邏輯控制器PLC（Programmable Logic Controller），目的是用來(lái)取代繼電器。以執(zhí)行邏輯判斷、計(jì)時(shí)、計(jì)數(shù)等順序控制功能。提出PLC概念的是美國(guó)通用汽車(chē)公司。PLC的基本設(shè)計(jì)思想是把計(jì)算機(jī)功能完善、靈活、通用等優(yōu)點(diǎn)和繼電器控制系統(tǒng)的簡(jiǎn)單易懂、操作方便、價(jià)格便宜等優(yōu)點(diǎn)結(jié)合起來(lái)，控制器的硬件是標(biāo)準(zhǔn)的、通用的。根據(jù)實(shí)際應(yīng)用對(duì)象，將控制內(nèi)容編成軟件寫(xiě)入控制器的用戶(hù)程序存儲(chǔ)器內(nèi)，使控制器和被控對(duì)象連接方便。 70年代中期以后，PLC已廣泛地使用微處理器作為中央處理器，輸入輸出模塊和外圍電路也都采用了中、大規(guī)模甚至超大規(guī)模的集成電路，這時(shí)的PLC已不再是僅有邏輯(Logic)判斷功能，還同時(shí)具有數(shù)據(jù)處理、PID調(diào)節(jié)和數(shù)據(jù)通信功能。國(guó)際電工委員會(huì)(IEC)頒布的可編程控制器標(biāo)準(zhǔn)草案中對(duì)可編程控制器作了如下的定義：可編程控制器是一種數(shù)字運(yùn)算操作的電子系統(tǒng)，專(zhuān)為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)。它采用了可編程序的存儲(chǔ)器，用來(lái)在其內(nèi)部存儲(chǔ)執(zhí)行邏輯運(yùn)算，順序控制、定時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算等操作的指令，并通過(guò)數(shù)字式和模擬式的輸入和輸出，控制各種類(lèi)型的機(jī)械或生產(chǎn)過(guò)程。可編程控制器及其有關(guān)外圍設(shè)備，易于與工業(yè)控制系統(tǒng)聯(lián)成一個(gè)整體，易于擴(kuò)充其功能的設(shè)計(jì)。 可編程控制器對(duì)用戶(hù)來(lái)說(shuō)，是一種無(wú)觸點(diǎn)設(shè)備，改變程序即可改變生產(chǎn)工藝。目前，可編程控制器已成為工廠自動(dòng)化的強(qiáng)有力工具，得到了廣泛的普及推廣應(yīng)用。 可編程控制器是面向用戶(hù)的專(zhuān)用工業(yè)控制計(jì)算機(jī)，具有許多明顯的特點(diǎn)。 ①可靠性高，抗干擾能力強(qiáng)； ②編程直觀、簡(jiǎn)單； ③適應(yīng)性好； ④功能完善，接口功能強(qiáng)。 它是以微處理器為基礎(chǔ)，綜合了計(jì)算機(jī)技術(shù)、自動(dòng)控制技術(shù)和通訊技術(shù)而發(fā)展起來(lái)的一種新型工業(yè)控制裝置。根據(jù)2003年天津華維斯特自動(dòng)化立體倉(cāng)庫(kù)系統(tǒng)的實(shí)施，深入探討了PLC在自動(dòng)化立體倉(cāng)庫(kù)控制系統(tǒng)中的具體應(yīng)用。隨著計(jì)算機(jī)信息技術(shù)的發(fā)展 ，現(xiàn)代企業(yè)生產(chǎn)規(guī)模的不斷擴(kuò)大和競(jìng)爭(zhēng)的日益加劇 ，市場(chǎng)對(duì)企業(yè)物流系統(tǒng)提出了新的要求 ，自動(dòng)化立體倉(cāng)庫(kù)越來(lái)越受到關(guān)注并得到廣泛應(yīng)用。論文介紹西門(mén)子公司生產(chǎn)的S7200 PLC在自動(dòng)立體倉(cāng)庫(kù)的堆貨機(jī)用于自動(dòng)立體倉(cāng)庫(kù)的堆貨機(jī)的西門(mén)子公司導(dǎo)致的S7200 PLC的應(yīng)用。所有
