Today, automatic stereoscopic warehouse that links up the networks of factory information management system and production lines is the indispensable key link of puter integrate manufacture system (CIMS) and flexible manufacture system (FMS). Aiming at automatic storage system, has developed many kinds of hardware and software in the related fields, such as different kinds of inventory management software, system simulation software, figure monitoring and dispatching software, stacker and conveyor control software, bar code identification and tracking system, carrier robot, stacking manipulator, goods sorting system, stacker address recognition and detection system, stacker control system, cargo space detector, height detector, conveying system, stacking system and automatic guiding vehicle etc. Main Characteristics (1) out warehouse management, consulting and referring, reporting, documentation and inventory checking, alarming, monitoring and animation etc. Programmable Logic Controller is the first in the late 1960s in the United States, then called Plc programmable logic controller (Programmable Logic Controller) is used to replace relays. For the implementation of the logical judgment, timing, sequence number, and other control functions. The concept is presented Plc General Motors Corporation. Plc and the basic design is the puter functional improvements, flexible, generic and other advantages and relay control system simple and easy to operate, such as the advantages 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。 Third, adaptability good。與廠(chǎng)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)。 主要技術(shù)性能(1) 控制系統(tǒng)：　● 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?！　?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)。　●(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。以執(zhí)行邏輯判斷、計(jì)時(shí)、計(jì)數(shù)等順序控制功能。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。 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。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。 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)。 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。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。
