AGV(auTOmated Guided Vehicle)即自動導引車,是具備一定自主能力的運輸設備,在自動化物流系統和工廠自動化系統中具有重要的應用價值。 AGV是一種高度自動化產品,它所涉及的技術包括針對特定用途的車體結構、貨物移送機構、路徑導引技術、貨位檢測技術、防碰撞技術、驅動技術和控制技術。更深入的研究還包括多車協調與優化調度技術、智能控制技術等。 本文首先對AGV的發展及關鍵技術進行了總結與歸納,并分析了現有技術的特點與不足,在此基礎上設計了一個模擬貨物分揀的小型AGV系統。車體采用二輪驅動和前后萬向輪支承的結構,可以實現靈活的轉向和快速移動。導引方式采用光電傳感器路徑導引,以計數方式實現貨位識別檢測。ARM是一種高性能的嵌入式微處理器,AGV控制系統采用了基于ARM7核的微控制器LPC2210,其豐富的片上資源可以很方便地實現AGV的所有檢測、信息處理及控制功能。利用LPC2210的串行通信功能,再配合無線通信模塊建立與PC機的通信聯系,通過PC機實現對AGV小車的控制與調度。 制作完成后的AGV樣機在實驗室模擬環境下進行了性能測試,其性能指標均滿足設計要求。

Abstract: A laser module designer can use a fixed resistor, mechanical pot, digital pot, or a digital-to-analogconverter (DAC) to control the laser driver's modulation and bias currents. The advantages of a programmablemethod (POT or DAC) are that the manufacturing process can be auTOmated and digital control can be applied(e.g., to compensate for temperature). Using POTs can be a more simple approach than a DAC. There can be aslight cost advantage to using a POT, but this is usually not significant relative to other pieces of the design.Using a DAC can offer advantages, including improved linearity (translating to ease of software implementationand ability to hit the required accuracy), increased board density, a wider range of resolutions, a betteroptimization range, ease of use with a negative voltage laser driver, and unit-to-unit consistency

This application note describes a Linear Technology "Half-Flash" A/D converter, the LTC1099, being connected to a 256 element line scan photodiode array. This technology adapts itself to handheld (i.e., low power) bar code readers, as well as high resolution auTOmated machine inspection applications..

本課題選用光電傳感器作為導向傳感器,以設計出使用方便、價格低廉、引導精確、響應速度快的AGV工廠自動運貨車為研究目的。 AGV是自動導引運輸車(auTOmated Guided Vehicle)的英文縮寫,是當今柔性制造系統(FMS)和自動化倉儲系統中物流運輸的有效手段。自動導引運輸車系統的核心設備是自動導引運輸車,作為一種無人駕駛工業搬運車輛,一般用蓄電池作為動力,載重量從幾公斤到上百噸,工作場地可以是辦公室、車間,也可以是港口、碼頭。 現代的AGV都是由計算機控制的,車上裝有微處理器。多數的AGVS配有系統集中控制與管理計算機,用于對AGV的作業過程進行優化,發出搬運指令,跟蹤傳送中的構件。裝備有電磁或光學等自動導引裝置,能夠沿規定的導引路徑行駛,具有安全保護以及各種移載功能的運輸車,工業應用中不需駕駛員的搬運車,以可充電之蓄電池為其動力來源。一般可透過電腦來控制其行進路線以及行為,或利用電磁軌道(electromagnetic path-following system)來設立其行進路線,電磁軌道黏貼於地板上,自動導引運輸車則依循電磁軌道所帶來的訊息進行移動與動作。 AGV以輪式移動為特征,較之步行、爬行或其它非輪式的移動機器人具有行動快捷、工作效率高、結構簡單、可控性強、安全性好等優勢。與物料輸送中常用的其他設備相比,AGV的活動區域無需鋪設軌道、支座架等固定裝置,不受場地、道路和空間的限制。因此,在自動化物流系統中,最能充分地體現其自動性和柔性,實現高效、經濟、靈活的無人化生產。 AGV的常用引導方式有電磁感應式引導,激光引導,電磁陀螺式引導等,通過對這種引導方式的比較,我們選用光電傳感器作為導向傳感器,因為光電檢測方法具有精度高、反應快、非接觸等優點,而且可測參數多,傳感器的結構簡單,形式靈活多樣。選用紅外傳感器作為蔽障傳感器,因為紅外線對外界環境光線的適應能力比較強。用直流測速發電機作為速度傳感器。設計出使用方便、價格低廉、引導精確、響應速度快的AGV。
