Problems solved by technology

[0004] However, no matter what positioning and guidance scheme is based on, positioning and guidance are usually performed in a large location area. In this environment, due to cost and efficiency considerations, the positioning accuracy is often low. In the case of high-precision positioning, it cannot meet the positioning requirements

Embodiment 1

[0036] Example 1, such as figure 1 Shown: The system includes an AGV trolley. The mechanical structure of the trolley is not much different from the existing technology. It has a walking structure and a driving device 2. Specifically, it includes two driving wheels, one on the left and one on the right. 1 on both sides. In this case, each driving wheel is controlled by a driving motor independently, and the posture of the vehicle body 1 can be adjusted according to the left and right differential speed.

[0037] The car body 1 is connected with a scanning device 4, in this embodiment, as figure 1 As shown, the scanning device 4 can be a laser head, which performs laser scanning within a range of 360° or 180° in front, and can initially set a value X0, which is the identified scanning radius for detecting the auxiliary positioning device 5 .

[0038] In this example, if figure 1 As shown, the auxiliary positioning device 5 is a reflector, and there are at least two, which ar...

Abstract

The invention relates to the field of logistics automation, and specifically relates to a control system and method for the secondary precise positioning of an AGV. The system is implemented through the following technical scheme that the system comprises an AGV and an auxiliary positioning device; the AGV comprises a vehicle body, a drive unit, a controller and a scanning device disposed on the vehicle body; the controller comprises a switching device for switching a positioning algorithm. The objective of the invention lies in providing the control system and method for the secondary precisepositioning of the AGV, and the system can trigger the secondary precise positioning in a large work occasion, and switches the positioning algorithm, and continues to work at high precision.

Description

technical field [0001] The invention relates to the field of logistics automation, in particular to a control system suitable for secondary precise positioning of an AGV and a control method thereof. Background technique [0002] AGV, or automatic guided vehicle, refers to a transport vehicle equipped with an automatic guidance device that can travel along a prescribed guidance path. AGV has a wide range of uses, and can replace manual tasks such as stacking, unstacking, and handling in the storage environment. [0003] In the actual work of AGV, the technical solution of positioning and navigation is particularly important. In the existing technology, electromagnetic navigation, magnetic navigation and laser navigation are common. Electromagnetic navigation is one of the more traditional navigation methods. It embeds metal wires on the driving path of the AGV, loads the guiding frequency on the metal wires, and realizes the navigation of the AGV by identifying the guiding ...
