Embodiment Construction

[0018] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] The present invention installs an automatic off-track correction device on the AGV trolley to ensure personal safety and improve production efficiency. It is equipped with a binocular vision sensor, which automatically captures images and compares them with existing images in the memory, so that it can track accurately and automatically. In addition, infrared sensors and ultrasonic sensors are installed. When someone appears in front of the AGV car, an alarm will be issued and the brakes will be applied to ensure personal safety. When the safety is determined, the AGV car will run again. This can be used to ensure personal safety and the safety of factory logistics and transportation. ...

Abstract

The invention discloses an automatic off-track correction device and an automatic off-track correction method for an AGV trolley. The device includes: an infrared sensor, an ultrasonic sensor, a binocular vision sensor, left and right electromagnetic sensors, an alarm, and a printed circuit board. It also includes a microcontroller, a wireless information transmission module, a power supply module, a motor driver, a memory, and an AGV automatic control system, wherein the microcontroller is used to identify the landmarks of the magnetic track according to the image collected by the binocular vision sensor, and according to the magnetic The track landmark image analyzes the direction of the magnetic track, and then sends the corresponding command to the motor driver to correct the deviation of the trolley. The invention realizes the functions of automatic avoidance alarm and automatic track deviation correction of the AGV trolley, creates a man-machine friendly working environment, avoids the injury of the staff, and can improve the production efficiency of the AGV trolley.

Description

technical field [0001] The invention relates to an automatic off-track correction device and an automatic off-track correction method for an AGV trolley. When the AGV trolley deviates from the track or derails, it can automatically find the original path and then correct it. Background technique [0002] AGV (Automated Guided Vehicle, unmanned guided vehicle) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guidance path, with safety protection and various transfer functions. [0003] Most of the AGV cars are used on the factory logistics transportation line, and it is inevitable that they will be touched by people who are working during normal driving or other accidents will cause them to deviate from the original track. When the position of the existing magnetic track AGV trolley deflects, an alarm will be issued remotely, and the remote staff will then adjust the on-site staff ...
