Embodiment Construction

[0048] Principle of the present invention is specifically described as follows:

[0049] (1) The first part of the technical solution: the fixing device of the system mainly includes a loading platform, an unloading platform, multiple workbenches, multiple AGV waiting areas, and electromagnetic tracks connecting these fixing devices. In addition, the system also includes multiple movable AGVs. The data that needs to be obtained to measure the system includes the following categories:

[0050] First, the length of the electromagnetic track between two fixed devices such as loading platforms, unloading platforms, workbenches, and AGV waiting areas.

[0051] Second, the time required for AGV to load and unload work on the loading platform, unloading platform, and workbench and the processing time of each workbench.

[0052] Third, the running speed of the AGV and the reaction time to avoid obstacles when encountering obstacles.

[0053] (2) The second part of the technical pla...

Abstract

The invention relates to an AGV quantity and work task matching method in an AGV production scheduling system. The multi-track interactive AGV production scheduling system comprises multiple work stations, multiple AGVs and multiple operation tracks, various types of information in a production process are interacted, a present work task and an operation line are selected by each AGV in the operation process according to an instant system state, and system complexity and AGV decision instantaneity make the AGV quantity and the work tasks be difficult to pre-match reasonably. Through the method, a system operation state can be pre-simulated, required AGV quantity can be pre-determined under the condition of certain work tasks, bearable largest work tasks can be determined under the condition of certain AGV quantity, required work time can be pre-determined under the condition of the certain AGV quantity and the certain work tasks, and thereby the work tasks and the AGV quantity can be reasonably matched.

Description

technical field [0001] The invention relates to a method for simulating a multi-track and interactive AGV production dispatching system by adopting a multi-Agent method so as to make the working tasks and the number of AGVs match each other. The invention belongs to the technical field of AGV production scheduling. Background technique [0002] Automated Guided Vehicle (AGV for short) is a transportation vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of traveling along a prescribed guiding path, with safety protection and various transfer functions. AGV does not require a driver in industrial applications. It uses a rechargeable battery as its power source, and controls its route and behavior through a computer system. Electromagnetic tracks are usually used to set up the travel route of the AGV. The electromagnetic track is attached to the floor, and the AGV moves and moves according to the information brought by the electroma...
