    一、 什么是AGV

    AGV ( Automatic Guided Vehicle)即自動導引小車,它是一種以電池為動力,裝有非接觸導向裝置和獨立尋址系統的無人駕駛自動化搬運車輛。它的主要特征表現為具有小車編程、停車選擇裝置、安全保護以及各種移載功能,并能在計算機的監控下,按指令自主駕駛,自動沿著規定的導引路徑行駛,到達指定地點,完成一系列作業任務。其系統技術和產品已經成為柔性生產線、柔性裝配線、倉儲物流自動化系統的重要設備和技術。


    通常多臺AGV與控制計算機(控制臺),導航設備,充電設備以及周邊附屬設備組成AGV系統,其主要工作原理表現為在控制計算機的監控及任務調度下,AGV可以準確的按照規定的路徑行走,到達任務指定位置后,完成一系列的作業任務,控制計算機可根據AGV自身電量決定是否到充電區進行自動充電。


    AGV自動導引車是融合了電子技術和機械技術的典型機電一體化產品。隨著各種AGV新產品不斷開發,AGV自動導引車技術不斷發展,先進的傳感器、電子電力器件、光電器件、計算機、控制技術、電池技術、機構學等高新技術成果逐漸地集成到AGV新產品及其系統技術中去,使它的技術附加值越來越大。

    1. What is AGV

    AGV (Automatic Guided Vehicle) is an automatic guided vehicle, which is an unmanned automated handling vehicle powered by a battery, equipped with a non-contact guiding device and an independent addressing system. Its main features are that it has car programming, parking selection device, safety protection and various transfer functions, and can drive autonomously according to instructions under the monitoring of the computer, automatically drive along the specified guide path, and reach the designated place. Complete a series of homework tasks. Its system technology and products have become important equipment and technologies for flexible production lines, flexible assembly lines, and warehousing and logistics automation systems.

    Usually multiple AGVs and control computers (console), navigation equipment, charging equipment and peripheral auxiliary equipment form an AGV system. Its main working principle is that under the monitoring and task scheduling of the control computer, the AGV can accurately follow the specified path. , After reaching the designated position of the task, a series of tasks are completed, and the control computer can decide whether to go to the charging area for automatic charging according to the power of the AGV itself.

    二、AGV的基本結構及典型部件

    2. The Basic Structure and Typical Components of AGV

    AGV的基本結構   The Basic Structure of AGV

    1) 車體:由車架和相應的機械裝置所組成,是AGV的基礎部分,是其他總成部件的安裝基礎。

    2) 蓄電和充電裝置:AGV常采用24V和48V直流蓄電池為動力。蓄電池供電一般應保持連續工作8小時以上的需要。

    3) 驅動裝置:由車輪、減速器、制動器、驅動電機及速度控制器等部分組成,是控制AGV正常運行的裝置。其運行指令由計算機或人工控制齊發出,運行速度、方向、制動的調節分別由計算機控制。為了安全,在斷電時制動裝置能靠機械實現制動。

    4) 導向裝置:接受導引系統的方向信息,通過轉向裝置來實現轉向動作。

    5) 車上控制器:接受控制中心的指令并執行相應的指令,同時將本身的狀態(如位置、速度等)及時反饋給控制中心。

    6) 通信裝置:實現AGV與地面控制站及地面監控設備之間的信息交換。

    7) 安全保護裝置:包括對AGV本身的保護、對人或其他設備的保護等方面。

    8) 移載裝置:與所搬運貨物直接接觸,實現貨物轉載的裝置。

    9) 信息傳輸與處理裝置:對AGV進行監控,監控AGV所處的地面狀態,并與地面控制站實時進行信息傳遞。

    1) Car body: It is composed of the frame and the corresponding mechanical devices. It is the basic part of the AGV and the installation basis of other assembly components.

    2) Power storage and charging device: AGVs often use 24V and 48V DC batteries as power. The battery power supply should generally be maintained for more than 8 hours of continuous work.

    3) Driving device: It is composed of wheels, reducer, brake, driving motor and speed controller. It is the device that controls the normal operation of AGV. Its running instructions are issued by computer or manual control, and the adjustment of running speed, direction and braking is controlled by computer respectively. For safety, the braking device can be mechanically braked in the event of a power failure.

    4) Guiding device: receive the direction information of the guiding system, and realize the steering action through the steering device.

    5) On-board controller: accepts the instructions of the control center and executes the corresponding instructions, and at the same time feeds back its own status (such as position, speed, etc.) to the control center in time.

    6) Communication device: realize information exchange between AGV and ground control station and ground monitoring equipment.

    7) Safety protection device: including the protection of the AGV itself, the protection of people or other equipment, etc.

    8) Transfer device: a device that directly contacts with the goods to be carried to realize the transfer of goods.

    9) Information transmission and processing device: monitor the AGV, monitor the ground state where the AGV is located, and transmit information in real time with the ground control station.
