Problems solved by technology

However, the existing mutual exclusion sets between routes are mostly configured manually or semi-automatically, which is difficult and requires a lot of work. In addition, the configuration results are prone to deadlocks, and it is difficult to find configuration errors.

Embodiment Construction

[0021] Multiple mobile robots walk on their own routes and perform their tasks independently. A single mobile robot cannot perceive the position and operating status of other mobile robots. How to avoid collisions between mobile robots and ensure efficient logistics is what the traffic control system needs to solve important question.

[0022] Mobile robot A moves from 1→2→3→4, and mobile robot B moves from 5→6→7→8. If the size of the mobile robot is not considered, that is, the mobile robot is regarded as a particle, then mobile robot A and mobile robot B do not perform traffic control, such as figure 1 shown.

[0023] But mobile robots are not possible regardless of their physical size, so regulation is required in this case. Traffic control is based on the mutual exclusion relationship between routes to approve and reject routes. Such as figure 2 Shown: route 1→2, mutually exclusive with routes 6→7, 7→8, 8→9, in other words, when mobile robot A applies for passing thro...

Abstract

The invention discloses a traffic control method for a mobile robot system. The method comprises steps that 1, a physical dimension of a mobile robot and the position of points on operation lines are defined; 2, for each point on the operation lines, the profile information of the mobile robot on the point is acquired in combination with the physical dimension of the mobile robot, and the profile information of the mobile robot on each operation line is acquired; 3, for a first line, whether profiles of the mobile robot on the first line and a second line intersect is determined through calculation, if yes, the first line and the second line are exclusive; and 4, whether profiles of the mobile robot on the first line and other lines intersect is determined through calculation, and a set of all the exclusive lines is acquired. The method is advantaged in that complete automation of the exclusive set of the lines is realized, dead lock of a configuration result does not easily occur, and problems of easily-generated errors and large workload because of the artificially-configured exclusive set are solved.

Description

technical field [0001] The invention relates to a method for transporting inventory materials in an inventory system, in particular to a traffic control method for a mobile robot system. Background technique [0002] Modern inventory systems, such as e-commerce warehouses, place extremely high demands on fast and accurate stock material sorting during order fulfillment. In the development in recent years, the speed, efficiency and automation of inventory storage and retrieval have been greatly improved through mobile robot cargo storage sorting and other related technologies. The operating efficiency of the mobile robot with huge data in the inventory environment will directly affect the efficiency of the entire inventory system, and the traffic control system in the inventory system controls the movement of all mobile robots, and its efficiency directly affects the time for the mobile robot to complete the handling task. [0003] Multiple mobile robots walk on their own ro...
