An Automatic Guidance Vehicle Based on UWB Technology

Abstract

The invention discloses an ultra-wideband technology based automated guided vehicle. The ultra-wideband technology based automated guided vehicle comprises a transport vehicle, a label arranged on thetransport vehicle, and a plurality of detecting base stations, wherein the detecting base stations are arranged at the periphery of a warehouse, and the detecting range covers the whole warehouse; the detecting base stations are in coupling connection with a positioning server; the transport vehicle comprises a vehicle body, front wheels and rear wheels which are arranged below the vehicle body as well as a controller, a steering gear box and a drive device, which are arranged on the vehicle body; and the steering gear box is arranged on a position, opposite to the front wheels, of the vehicle body. According to the ultra-wideband technology based automated guided vehicle disclosed by the invention, the detecting base stations and the label are arranged, so that the ultra-wideband technology can be effectively utilized to effectively position the position, in the warehouse, of the guided vehicle, automated guided driving of the vehicle is realized by positioning, and transportation, in the warehouse, of goods is realized through automation of the vehicle, and therefore, labour investment cost is effectively reduced, and transportation efficiency is greatly improved.

Description

technical field [0001] The present invention relates to a navigation vehicle, more particularly to an automatic navigation vehicle based on ultra-wideband technology. Background technique [0002] In the warehousing system, the shelf and the transport trolley are the two most important components in the warehousing system. The shelf is used to store the goods, and then the goods on the shelf are effectively transferred through the transport trolley to achieve the effect of sorting the goods. [0003] However, the transport trolley in the prior art is used by human driving, so a driver needs to be set up, which increases the usage cost of the storage system. At the same time, in the process of the larger storage system in the prior art, due to The shelves are high and the number of shelves is very large. Therefore, if the driver is not familiar with the distribution of the shelves, it is easy to get lost in the process of transferring the goods. Electronic records can be use...

Problems solved by technology

[0003] However, the transport trolley in the prior art is used by human driving, so it is necessary to set up a driver, which increases the use cost of the storage system. At the same time, in the process of the larger storage system in the prior art, due The shelves are high and there are a lot of shelves, so if the driver is not familiar with the distribution of the shelves, it is easy to get lost in the process of transferring the goods. At the same time, the electronic management of the goods has been realized in the existing technology. Electronic records can be used for the position of each cargo shelf. Therefore, if a positioning module is installed on the transport trolley, it is very feasible to navigate the transport trolley through the positioning module to avoid the problem of getting lost. However, the existing The distance between the larger warehouse shelves is generally not too large, basically about 1 meter, and some are even narrower, and the positioning error of the existing GPS positioning module is almost 1 meter, so if GPS positioning is used If the positioning of the transport trolley is carried out in a certain way, the positioning will be inaccurate due to the large error, so that the transport trolley cannot reach the designated position well.
