Material tracking method and system based on rail carrier

Abstract

The invention discloses a material tracking method and system based on a rail carrier, relates to the technical field of material tracking, and the system comprises a logistics automation system and aphysical entity tool for realizing material handling, the logistics automation system comprises a rail carrier, a lifting appliance, an automation control system, a displacement sensor, a weight sensor and network communication equipment; and the a logistics information model is a virtual logistics information system constructed by adopting an information technology, and the logistics informationmodel comprises a software tool, an information model and a hardware support. According to the method, the virtual identification code and logistics shell technology is adopted, the problem that logistics information is lost due to damage of a physical label is solved, and the method is suitable for severe environments such as whole-process material information tracking of a hot processing production scene; logistics information tracking and a production business process are combined and applied to lean production and accurate management and control, deep application of logistics data is achieved, and higher value is brought into play.

Description

technical field [0001] The invention relates to the technical field of material tracking, in particular to a material tracking method and system based on rail vehicles. Background technique [0002] In large-scale equipment and parts manufacturing enterprises, it has always been a difficult problem in the industry to realize automatic tracking of materials during the space transfer process of large items. On the one hand, due to the heavy weight of materials, components or products, manual handling or automatic transportation is not possible, and track-based load carriers such as rail flat cars, bridge cranes, and semi-gantry cranes are often used to achieve space transfer. On the other hand, due to the complex and harsh working environment, there are unfavorable factors such as high temperature, high dust, changing environment, iron interference, etc., paper or plastic labels, iron nameplates, RFID, etc. are easily damaged or cannot be identified, especially The heat proce...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing material tracking methods mainly use oil pen marks, paper or plastic labels, iron nameplates, RFID and other physical labels as the carriers of information transmission, which are easily damaged by thermal processing, oil dust, heat radiation, etc., causing Unrecognizable and lost logistics information between previous and subsequent processes; if secondary marking or relabeling is used, it will result in low work efficiency, increased costs, and the risk of repeated information entry errors

[0006] (2) In the process of material handling, logistics information such as handling tools, material names, pick / put location coordinates, operating time, and operation tasks are mostly recorded manually, or manual assisted operations are recorded in a single logistics automation system; The material handling scenario is multi-vehicle type, multiple transshipment, logistics and production business are closely related, resulting in logistics information cannot be automatically transmitted with the material, forming an island of logistics information

[0007] (3) Due to the lack of integrated application of logistics object modeling, virtual space layout and production business modeling, the existing material tracking scheme cannot closely serve production management and cannot meet the needs of lean production and precise control
