Embodiment
[0035] Establishment and Working Method for Semantic Web of Flexible Production Line AGV System See Figure 1 to 3 , figure 1 It is a factory-owned line plane arrangement and an independent operation of AGV. figure 2 It is a semantic Web flow chart, image 3 It is a semantic Web application flowchart provided by the present invention.
[0036] Wherein, the first part of the semantic WEB establishment method includes the following steps:
[0037] The first step is to semantically define the production line field information.
[0038] Based on both a flat design / arrangement map or intelligent AGV field scanning the plane environment map built, the gridization, the name of each of the working sites and related warehouses, and its docking position of the AGV docking position , Marked "Stone 1", "Stone 2", "Raw Material 1", "Raw Material 2", "Find Library 1", "Toolbase 1", "Waste Library 1" ... and other positions, each tag It also contains its positioning information on the map wit...

The invention discloses a method for establishing and working the semantic web of a flexible production line AGV system. The steps of establishing the semantic web are as follows: firstly, semantic marking being carried out on each working position of the production line and the position of a warehouse site according to a map; then marking the working content of the marking station according to the process flow of the production line; carrying on the goods and the location, the quantity, the operation word correlation analysis to the site demand information, wherein semantic Web applications include site request information collection, speech recognition, task resolution, AGV scheduling and control module. An application example is that a station sends out request information, a recognition module recognizes the request speech, a semantic analysis module performs semantic analysis and publishes complete task information, each autonomous navigation AGV decides whether to respond according to its own position and load, and a scheduling and control module designates one of the responding AGVs to execute the task with the fastest principle. The invention has the beneficial effects of improving and improving the working quality and efficiency of the AGV and the dispatching system.
Description
Technical field [0001] The present invention relates to the field of intelligent control, and more particularly to the establishment of a flexible production line AGV system semantic Web. Background technique [0002] Automatic boot transport vehicle (AGV) has high degree of automation, flexible application, long-term long distance high-intensity, safe and high reliability, low cost, easy maintenance, beauty, etc., as a contact and regulating discrete logistics management system automation Handling and unloading means, wide application in manufacturing companies. With the continuous development of flexible manufacturing systems, production line automated logistics technology and "smart plant" technology, research and development of various types of AGV, its technical level is getting higher and higher, and the application is increasingly expanding. For example, if there is a railroad, the wireless navigation AGV has developed a non-rail autonomous navigation AGV, which can genera...
