自动导航物流AGV设计 PAGE I 摘要 AGV自动引导小车（英文名Automated Guided Vehicle）是一种工作过程中根据系统指令自己运作的自动化物流运输小车，它装备了包括光电类，电磁类和声学类的机械设备，能够根据控制系统发出的命令进行货物的移载和装卸。本设计采用AT89C51单片机作为小车的控制系统硬件，通过搭配各类传感器实现循迹设计，避障设计，装卸设计。循迹设计本设计采用了市场上应用较多的电磁感应来实现，避障设计本设计用过采用超声波传感器来实现，装卸设备本设计通过步进电机来带动传送带运输货物，通过对这几个模块的设计，AGV小车的自动导航就能够实现，同时也能完成自动导航物流AGV小车这一设计。 关键词 AT89C51单片机；AGV物流小车；自动导航；传感器 全套图纸加扣 3346389411或3012250582 Abstact AGV Automated Guided Vehicle (English name Automated Guided Vehicle) is an automated logistics transportation vehicle that operates according to system instructions during work. It is equipped with mechanical equipment including optoelectronics, electromagnetics and acoustics, which can be issued according to the control system. Order the transfer and loading and unloading of goods. This design uses AT89C51 single-chip microcomputer as the control system hardware of the car, and realizes tracking design, obstacle avoidance design and loading and unloading design by matching various sensors. The tracking design is designed using electromagnetic induction that is widely used in the market. The obstacle avoidance design has been implemented using ultrasonic sensors. The loading and unloading equipment design uses a stepper motor to drive the conveyor belt to transport goods. The design of the module, the automatic navigation of the AGV car can be realized, and the design of the AGV car of the automatic navigation logistics can also be completed.
