Embodiment Construction

[0029] The technical solutions of the present invention will be further specifically described below through the embodiments of the present invention and in conjunction with the accompanying drawings.

[0030] figure 1 It is a schematic flowchart of an embodiment of a method for controlling multiple mobile robots to run concurrently proposed by the present invention, which specifically includes the following steps:

[0031] 1) The control terminal assigns the carrying task to the mobile robot; the carrying task in this embodiment is converted according to the inventory operation order;

[0032] 2) The control end plans a driving path according to the starting point and end point specified by the carrying task assigned to the mobile robot and the driving state of other mobile robots; walking section) or path planning based on the principle of the shortest path;

[0033] 3) The control end compares the travel path of the assigned mobile robot obtained in step 2) with the trave...

Abstract

The invention discloses a method and system for controlling a plurality of mobile robots to operate in a parallel manner and belongs to the technical field of automation and intelligentization of a warehousing system. The control method comprise the following steps: carrying tasks are distributed via a control end, path planning operation is performed for the mobile robots to which the tasks are distributed, path planning results are sent to the mobile robots, real time position state information is reported by the mobile robots, the position state information reported by all the mobile robotsis processed comprehensively via the control end, possible conflict conditions are determined, conflict evasion information is generated in real time and sent to the mobile robot, and the mobile robots evade each other in real time during operation according to the evasion information till terminal points are reached. The control system comprises a task assigning module, a path planning module, aconflict coordination module, a message communication module, a processor and a storage device. Via the method and system disclosed in the invention, stateful interaction between the mobile robots and the control system is prevented as much as possible, message communication traffic is effectively reduced, and overall operation efficiency of the system is improved.

Description

technical field [0001] The invention relates to the technical field of automation and intelligence of storage systems, in particular to a method and system for controlling multiple mobile robots to run concurrently. Background technique [0002] With the rapid development of modern e-commerce, the volume of customer orders is increasing day by day, and the operation frequency of commodity inventory is extremely high, with various categories and huge quantities. Under the traditional operation mode, problems such as imperfect data management, unreasonable warehouse location planning, and low manual operation efficiency have seriously restricted the development of related enterprises. How to use modern and advanced supply chain management, logistics business optimization and mobile robot control technology to realize the visualization, automation and intelligence of the whole process of warehouse management, improve the efficiency of in-store and out-of-warehouse operations, a...
