Magnetic navigation AGV (Automated Guided Vehicle) control system and method

Abstract

The invention relates to a magnetic navigation AGV (Automated Guided Vehicle) control system and method. Two driving wheels on the bottom surface of a vehicle body are fixed to the left side and the right side of the middle part respectively, and are called left driving wheel and right driving wheel; four universal wheels are fixed to four corners; an RFID (Radio Frequency Identification Device) sensor is fixed to the center; two magnetic sensors are fixed in front of and behind the RFID sensor respectively; a driving system and a control unit are fixed in the vehicle body; the driving system comprises a motor driver and a motor; an ultrasonic sensor is arranged at the front end of the vehicle body; in a circuit connection, the ultrasonic sensor, the magnetic sensors and the RFID sensor are connected with the control unit in a one-way form through an RS232 serial port; the control unit is connected with the motor driver in a one-way form through a 485 bus; the motor driver is connected with the motor in a one-way form to control the left driving wheel and the right driving wheel to run. The magnetic navigation AGV control system has the technical effects of stable and reliable data transmission, high efficiency, capability of realizing bidirectional movement and reversing of the AGV vehicle body, easiness and convenience in magnetic bar guide line pavement, and easiness in route change.

Description

technical field [0001] The invention relates to logistics handling equipment, in particular to a magnetic navigation AGV control system and control method. Background technique [0002] AGV (Automated Guided Vehicle, referred to as AGV) is an unmanned conveying equipment that automatically drives and completes material transfer and loading and unloading according to a set route or a set map under the control of a dispatch system or manual instructions. At present, the industry The AGV navigation methods that have appeared mainly include geomagnetic navigation, optocoupler navigation, laser reflection navigation, visual navigation, inertial navigation, ultrasonic navigation, etc. The reliability of these navigation methods is greatly affected by the outside world, and the requirements for the environment are too high. Poor, low precision, high manufacturing cost, relatively harsh environmental requirements, and the car can not achieve two-way movement and reverse, which is no...

Problems solved by technology

At present, the AGV navigation methods that have appeared in the industry mainly include geomagnetic navigation, optocoupler navigation, laser reflection navigation, visual navigation, inertial navigation, ultrasonic navigation, etc. The reliability of these navigation methods is greatly affected by the outside world, and the environmental requirements are too high. The reliability of the lead is poor, the precision is low, the manufacturing cost is high, and the environmental requirements are relatively harsh, and the trolley cannot realize two-way movement and reverse, which is not conducive to control
