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 rail deviation correction device and automatic rail deviation correction method for an AGV trolley. The automatic rail deviation correction device is composed of an infrared sensor, an ultrasonic sensor, a binocular vision sensor, left and right electromagnetic sensors, an alarm device, a printed circuit board, a microcontroller, a wireless information transmission module, a power source module, a motor driver, a memory, and an AGV automatic control system. The microcontroller is configured to identify a magnetic track landmark based on an image acquired bythe binocular vision sensor, analyze the magnetic track direction based on the magnetic track landmark, and send a corresponding instruction to the motor driver to carry out trolley deviation correction. According to the invention, the automatic people avoidance and alarming as well as automatic rail deviation correction function of the SGV trolley is realized; the human-machine friendly workingenvironment is created; the staff is protected from being injured; and the production efficiency of the AGV trolley is improved.

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 ...
