High-safety transport vehicle with automatic positioning system

Abstract

The invention discloses a high-safety transport vehicle with an automatic positioning system. The high-safety transport vehicle comprises a power supply unit and a driving system, wherein the driving system at least comprises a controller and a driving unit and a hydraulic unit which are controlled by the controller. The high-safety transport vehicle further comprises a safety protection system.The safety protection system comprises a front sensor arranged at the front side of a lifting portal frame, a rear sensor arranged at the rear side of the driving system, lateral sensors symmetrically arranged at the two sides of the rear sensor, and an inclined scanner arranged at the rear side of the lifting portal frame. The high-safety transport vehicle provided by the technical scheme mainly has the following advantages: by use of a laser automatic positioning mode, the precision advantage is high, and the cost advantage is greater; the travel line of the transport vehicle can be changed randomly; and besides, the transport vehicle employs a special sensor arrangement structure, can eliminate sensing blind angles to the maximum degree and ensures safety of the transport vehicle.

Description

technical field [0001] The invention relates to the technical field of industrial equipment, in particular to a high-safety transport vehicle with an automatic positioning system. Background technique [0002] AGV is the abbreviation of (Automated Guided Vehicle), which means "automatically guided transport vehicle", which generally refers to the automatic guidance device equipped with electromagnetic or optical, etc., which can drive along the prescribed guiding path, with safety protection and various The transport vehicle with transfer function, AGV belongs to the category of wheeled mobile robot (WMR—Wheeled Mobile Robot), also known as transfer robot. The most frequently used occasions of AGV are mostly in factories with a high degree of automation. [0003] The most common navigation and positioning methods in AGV are: magnetic strip navigation and RFID positioning. The way of magnetic strip navigation is: laying a landmark magnetic strip on the bottom surface, and a ...

AI Technical Summary

Problems solved by technology

[0004] Commonly used navigation and positioning modes mainly have the following disadvantages: affecting the flatness of the ground, low positioning accuracy, and high layout costs

The magnetic strip has a certain thickness. When the magnetic strip guide rail is laid, the magnetic strip will be higher than the ground. When the AGV forms to the fork, the driving wheel needs to cross the magnetic strip, which will cause the ground flatness problem

At the same time, in general, the accuracy of magnetic navigation sensors is not high

On the other hand, the price of magnetic strips and RFID radio frequency tags is relatively high, which increases the cost of the overall layout to a certain extent

At the same time, the current "Automatic Guided Transport Vehicle" is not safe enough, and collision accidents often occur, affecting production
