AGV operation optimization system and method based on double-layer space-time network structure

Abstract

The invention discloses an AGV operation optimization method based on a double-layer space-time network structure, and belongs to the technical field of AGV operation scheduling, and the method comprises the steps: firstly, enabling a production execution master control machine to import a production task, and enabling the production execution master control machine to select a to-be-processed task; the AGV dispatching equipment judges whether available idle AGVs exist at the current moment or not, dispatches the idle AGVs to reach the station area to take goods, and sends the goods to the warehouse-out area; and after the AGV sends the cargoes to the warehouse-out area, the AGV returns to the station area on the original road to put the trays and the remaining cargoes back, and the station master control machine updates the state of the AGV and waits for a next cycle task instruction. According to the invention, by adopting the scheme of statically scheduling the AGV and planning the path, the execution time of each task and the shortest time consumed for task conversion are ensured, so that the automatic stereoscopic warehouse is ensured to efficiently and orderly complete the specified carrying task without conflicts, the task assignment and operation sequence problems of the AGV in the automatic stereoscopic warehouse work are solved, and the working efficiency of the automatic stereoscopic warehouse is improved. Therefore, AGV scheduling and path optimization in the automatic stereoscopic warehouse are realized.

Description

technical field [0001] The invention belongs to the technical field of AGV operation scheduling, and in particular relates to an AGV operation optimization system and method based on a double-layer space-time network structure. Background technique [0002] The AGV system is a system composed of several independently operating AGVs. As an important part of intelligent manufacturing, it is more and more widely used in the logistics industry. It performs the work of porters in the warehouses of major companies and the terminals of various ports. . At present, the demand for AGV robots in China is increasingly strong, and they are mainly used in production, logistics, inspection and other industries. The production and manufacturing fields such as the automobile industry and home appliance manufacturing are still the main demand markets for AGVs in China. The two major industries have stable demand for AGVs, but there are some deficiencies in the management and application of ...

Problems solved by technology

[0004] In order to overcome the problems in the prior art that the AGV system has many short-distance storage operations, many AGV conflicts, and many shelf structural corners, it is difficult to obtain a conflict-free AGV path planning solution in a short period of time, etc., the present invention Provides an AGV operation optimization system and method based on a two-layer space-time network structure. By adopting static scheduling of AGVs and planning path schemes, adjusting the connection schemes of each task, reasonably assigning tasks to each AGV, and ensuring the execution of each task Time-consuming and time-consuming conversion between tasks is the shortest, reducing unnecessary time-consuming due to AGV path conflicts, so as to achieve the shortest overall completion time, to ensure that the automated three-dimensional warehouse can complete the designated handling tasks efficiently and orderly without conflicts, and solve the problem of AGV in Task assignment and job sequence in automatic three-dimensional warehouse work, so as to realize AGV scheduling and path optimization in automatic three-dimensional warehouse
