Embodiment Construction

[0038] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0039] The flowchart of an embodiment of the AGV motion control method of the present invention is as figure 1 shown.

[0040] In step 101, the travel plan of the AGV is determined according to the path length and the predetermined deceleration. In one embodiment, the planning can be carried out according to the path length and the deceleration of the vehicle, and the travel speed and deceleration distance conforming to the travel length can be set to generate a travel plan. In one embodiment, the maximum travel speed and the deceleration point can be included in the travel plan, so as to ensure that the AGV reaches the destination accurately, while minimizing the time and improving efficiency.

[0041] In step 102, the AGV is driven to move according to the travel plan. In one embodiment, an instruction can be issu...

Abstract

An automated guided vehicle (AGV), and a motion control method and device. The control method comprises: (101) determining a route plan of the AGV according to a path length, a predetermined acceleration and a predetermined deceleration, wherein the route plan includes a maximum driving speed and a deceleration point; and (102) driving the AGV to move according to the route plan, such that a highest driving speed of the AGV does not exceed the maximum driving speed and the AGV decelerates at the deceleration point. The method and the device of the present invention are capable of determining a route plan according to the path length the AGV is required to drive and the deceleration of the AGV, enabling the AGV to drive itself according to the route plan, achieving optimal customization of the route of the AGV, ensuring that the AGV is capable of more precisely stopping at a destination and enhancing parking accuracy, and at the same time reducing time wastage and enhancing operational efficiency so as to meet high-speed operational requirements.

Description

technical field [0001] The invention relates to the technical field of logistics, in particular to an AGV (Automated Guided Vehicle, automatic guided transport vehicle) and a motion control method and device. Background technique [0002] In the field of warehousing and logistics, the degree of automation is generally low. Existing logistics automation equipment often slows down and stops after detecting the landmarks to be parked, or slows down to crawling speed after detecting the landmarks to be parked. , realize that the AGV stops at the target location after moving along the path. [0003] However, it is difficult to achieve the stability and accuracy of parking accuracy under different AGV load inertia conditions by using the method of slowing down and parking after detecting the landmark points to be stopped; and the method of slowing down to crawling speed will waste a lot of working time As a result, the tact is low and it is difficult to meet the high-speed operat...
