Navigation control method, intelligent warehousing system and automated guided vehicle

Abstract

The invention discloses a navigation control method, an intelligent warehousing system and an automated guided vehicle. The invention discloses a navigation control method for an automatic guided vehicle in a warehouse, and the method comprises the steps that an upper computer receives a moving instruction, wherein a global map is stored in the upper computer, and information of a positioning codeis stored in the global map; information of the positioning code of a moving path corresponding to the moving instruction is generated based on the global map according to the moving instruction, andthe information of the positioning code is sent; and a lower computer receives the information of the positioning code of the moving path and stores the information as a local map. According to the embodiment of the invention, the global map is stored in the upper computer, and the lower computer dynamically updates the current local map. The method has the advantages that the size of the local map is small, the processing speed of the lower computer is high, and therefore the response speed and real-time performance of the system can be improved.

Description

technical field [0001] The invention relates to the field of intelligent storage, in particular to a navigation control method for an automatic guided vehicle, an intelligent storage system and an automatic guided vehicle. Background technique [0002] With the rapid development of my country's e-commerce industry, diversified demands have emerged in various aspects of logistics. A package sorting system composed of sorting robots has emerged as the times require. This system not only ensures efficient package sorting, but also has real-time Responsive and distributed flexibility. In the current field of logistics and warehousing, more and more automatic guided vehicles (AGV) have been used to replace or supplement manual labor. The automatic guided vehicle can automatically receive the item handling task. Under the control of the program, it reaches the first position, gets the item, then walks to the second position, unloads the item, and continues to perform other tasks. ...

AI Technical Summary

Problems solved by technology

However, some special working conditions require the car to be parked at non-standard spacing, or there are multiple code spacings coexisting in the map

The above working conditions lead to a reduction in the flexibility of the AGV movement in the single-code-spacing mode, and the AGV needs to switch the code-spacing when it is stopped

[0004] By means of floating-point codes (decoding includes physical coordinates), physical coordinates can replace logical coordinates to realize unequal-spaced code maps. However, AGV needs to do decoding calculations for each code, which takes too much time, which affects the output frame rate and thus affects Speed ​​and stability of trolley movement
