1、2009機(jī)電工程技術(shù)年第38卷第08期物流車輛智能調(diào)度管理系統(tǒng)賴順橋，肖熠琳(廣州市光機(jī)電技術(shù)研究院廣東省現(xiàn)代控制與光機(jī)電技術(shù)公共實驗室，廣東廣州510663山.可以彌補(bǔ)企業(yè)a避 山。可以彌林企能依期,產(chǎn)方式的要求.提滯企 .產(chǎn)方式的翌求.提湍他收稿日期:2009-04-15，探討了系統(tǒng)的工作原理，更好地滿足企業(yè)JIT (Just In Time工廠智能系統(tǒng)文獻(xiàn) 標(biāo)識碼:B文章編號:1009-9492(200908-0019-031引言現(xiàn)代物流不僅要考慮從生產(chǎn)者到消費(fèi)者的貨物配送問題，還要考慮從供應(yīng)商到 生產(chǎn)者對原材料的采購，以及生產(chǎn)者本身在產(chǎn)品制造過程中的運(yùn)輸、保管和信息等 各個方面,從而全

2、面地、綜合性地提高經(jīng)濟(jì)效益和效率。中國加入 WTO后,經(jīng)濟(jì)發(fā) 展正面臨著全球經(jīng)濟(jì)大融合的嚴(yán)峻考驗，在激烈的競爭環(huán)境下，各企業(yè)紛紛實行供應(yīng) 商管理庫存(VMI、JIT (Just in time即時采購等先進(jìn)的供應(yīng)鏈管理，在生產(chǎn)方式上紛紛采用先進(jìn)的生產(chǎn)管理方式一一準(zhǔn)時生產(chǎn)方式(JIT生產(chǎn)。這些先進(jìn)管理方式的主要 目的都是為企業(yè)能夠?qū)崿F(xiàn) 零庫存”。然而，絕大部分的企業(yè)和工廠都忽視了一個重 要環(huán)節(jié) 材料裝卸貨環(huán)節(jié)(當(dāng)材料從供應(yīng)商出廠送到企業(yè)生產(chǎn)線上，必須經(jīng)過裝卸 貨，仍舊采用人工調(diào)度呼叫的管理方式。人工調(diào)度的方式大致如下：(1運(yùn)貨車輛到調(diào)度室用登記表登記；(2調(diào)度員通過對講機(jī)詢問在卸貨區(qū)的工作人員是

3、否可以調(diào)度該車輛進(jìn)入卸貨 區(qū)，如果不可以，則叫該車到 待車區(qū)”等工作人員通知；(3得到卸貨許可后，調(diào)度員要去 待車區(qū)”尋找該車輛進(jìn)入卸貨區(qū)卸貨。這種方式存在著出錯概率大、 效率低、易出現(xiàn)堵車、用工成本高等缺陷。本文介紹一套滿足現(xiàn)代化生產(chǎn)需求的物流車輛智能調(diào)度管理系統(tǒng) 徹底解決人 工調(diào)度方式存在的種種不足，實現(xiàn)貨車全自動、智能調(diào)度呼叫的管理方式，大大提高 貨場車位的使用周轉(zhuǎn)速度，減輕了人的勞動強(qiáng)度，提高了卸貨效率，確保工廠外圍送貨 車輛順暢有序運(yùn)作，從而大大地提高當(dāng)前工廠物流的效率，對企業(yè)的增產(chǎn)和增收起著積極的作用。2系統(tǒng)組成與工作原理2.1 系統(tǒng)組成系統(tǒng)組成如圖1所示。硬件系統(tǒng)主要包括計算機(jī)系

4、統(tǒng)、傳感器及信號采集系 統(tǒng)、通訊系統(tǒng)、LED顯示系統(tǒng)、語音廣播系統(tǒng)、電源系統(tǒng)等；軟件系統(tǒng)主要包括數(shù) 據(jù)采集模塊、無線通訊模塊、數(shù)據(jù)庫模塊、調(diào)度算法模塊、指揮室車輛登記模塊、 參數(shù)設(shè)置模塊、查詢統(tǒng)計模塊、打印模塊、LED顯示模塊、語音播放模塊、待車超時提示模塊、卸貨超時報警模塊及上位機(jī)界面設(shè)計模塊等。2.2 工作原理首先，每一個車位對應(yīng)一個車位狀態(tài)控制箱，即感應(yīng)式IC車位卡控制箱，能夠?qū)?時監(jiān)控該車位的使用情況。所有的車位狀態(tài)控制箱都通過無線網(wǎng)絡(luò)連接到服務(wù)器 ， 服務(wù)器中的數(shù)據(jù)庫系統(tǒng)同步記錄了車位的當(dāng)前狀態(tài)。當(dāng)貨車到達(dá)廠區(qū)請求進(jìn)入時，由指揮室將車牌號碼等信息錄入前臺計算機(jī)。計 算機(jī)通過網(wǎng)絡(luò)系統(tǒng)發(fā)

5、送登記信息并訪問服務(wù)器數(shù)據(jù)庫自動查詢和檢索，獲得該車對應(yīng)卸貨的區(qū)域和可卸貨的車位、相關(guān)車位狀態(tài)等信息。計算機(jī)系統(tǒng)根據(jù)這些信息，按預(yù)設(shè)的調(diào)度規(guī)則給出指令，提示該車能否立即進(jìn)入相關(guān)的卸貨區(qū)域卸貨，如果不能， 該車暫時在待車區(qū)等候。在待車區(qū)設(shè)有高亮度LED顯示屏和高音喇叭。當(dāng)卸貨車位空閑時，服務(wù)器根據(jù) 系統(tǒng)調(diào)度策略，自動選中待車區(qū)制造業(yè)信息化2009機(jī)電工程技術(shù)年第38卷第08期圖1系統(tǒng)組成示意圖的某貨車，負(fù)責(zé)調(diào)度呼叫的計算機(jī)通過無線網(wǎng)絡(luò)將調(diào)度信息發(fā)送到待車區(qū)的室 外高亮度LED顯示屏，同時通過高音喇叭同步呼叫提示該貨車進(jìn)入相應(yīng)車位卸貨。當(dāng)貨車進(jìn)入卸貨車位進(jìn)行卸貨時，車位上的傳感器感應(yīng)到有車，對應(yīng)的

6、車位狀態(tài) 控制箱上紅色指示燈亮，表示該車位忙。在規(guī)定的時間內(nèi)司機(jī)必須先將IC卡插入該車位對應(yīng)的車位狀態(tài)控制箱的IC卡插卡槽內(nèi)，如果插入的IC卡未得到驗證（IC卡內(nèi) 的信息與控制箱上顯示的信息不同或者超出了規(guī)定的時間未插卡，系統(tǒng)會認(rèn)為有異 常情況發(fā)生（該車停錯車位等，從而發(fā)出警報聲提示工作人員干預(yù)；如果插入卡槽的 IC卡通過驗證，服務(wù)器立即采集到該信息并更新數(shù)據(jù)庫。當(dāng)卸貨時間超出預(yù)設(shè)時間 時，車位狀態(tài)控制箱上該車位紅色超時報警指示燈閃亮，蜂鳴器鳴響直至卸貨完畢離 開或手動按鍵停止鳴響。當(dāng)卸貨完畢后，將IC卡從IC卡插卡槽內(nèi)拔出，司機(jī)把車開 走，車位上的傳感器感應(yīng)到已沒車，則控制箱上對應(yīng)綠色指示燈

7、亮，紅色指示燈滅，表示 該車位空閑，同時服務(wù)器立即采集到該信息并更新數(shù)據(jù)庫。如果IC卡拔出后，規(guī)定時 間內(nèi)司機(jī)沒把車開走，系統(tǒng)同樣會認(rèn)為有異常情況發(fā)生，從而發(fā)出警報聲提示工作人 員干預(yù)。貨車離開廠區(qū)前將IC卡交給保安或其他工作人員。對于以上發(fā)生的警報 , 指揮室計算機(jī)均能及時作出相應(yīng)的提示，提醒調(diào)度員通過電話等手段進(jìn)行管理。3軟件設(shè)計設(shè)計的物流車輛智能調(diào)度系統(tǒng)軟件模塊流程圖如圖2所示。下面對系統(tǒng)的各個模塊作簡要的說明：(1車位狀態(tài)采集模塊，本模塊主要負(fù)責(zé)監(jiān)控和采集車位狀態(tài)(有車或無車，并將此 車位狀態(tài)信息發(fā)送到上位機(jī)服務(wù)器(PC機(jī)；(2無線通信模塊，本模塊主要負(fù)責(zé)發(fā)送車位狀態(tài)、車牌號碼、系統(tǒng)控

11、低全社會的交易成本、優(yōu)化資源配置的重要作用。本系統(tǒng)主要用于企 業(yè)生產(chǎn)的重要環(huán)節(jié)一材料裝卸貨環(huán)節(jié)，以提高企業(yè)物流管理水平，降低企業(yè)生產(chǎn)成本。通過長時間白運(yùn)行調(diào)試，目前該系統(tǒng)已經(jīng)在某企業(yè)得到了很好應(yīng)用，對企業(yè)的增 產(chǎn)和增收發(fā)揮了積極的作用。相信隨著市場競爭的日益激烈，自動化、信息化的日益發(fā)展及土地資源的日益緊缺等客觀因素影響，物流車輛智能調(diào)度管理系統(tǒng)將會得 到企業(yè)和工廠的廣泛應(yīng)用。參考文獻(xiàn)：1馮耕中.物流信息系統(tǒng)M.北京:機(jī)械工業(yè)出版社，2009.2曹衍龍.Visual Basic系統(tǒng)開發(fā)實例精粹M.北京:人民郵電出版社,2005.3王豐現(xiàn)代物流配送管理M.北京:首都經(jīng)濟(jì)貿(mào)易大學(xué)出版社,2008.
