Abstract: There are a large number of information islands in the process of cross whole life cycle management of coal mechanical equipment, which leads to the inability to deepen the data application. To solve the above problems, the classification and coding system of coal mechanical equipment information for full life cycle management is designed. The system is based on the operation mode of the product chain, asset chain and value chain of the coal mechanical equipment full life cycle business process, combines the existing international, national, coal industry and related fields information classification and coding standards, and uses Unified Modeling Language (UML) and Object Oriented Analysis Method (OOA). Firstly, a hybrid classification method combining line classification method and surface classification method is used to classify coal mechanical equipment information. Secondly, the GTIN of the GS1 coding system is used to realize the unique mark of coal mechanical equipment category, and the additional attribute method is used to associate MJLBM-1 code of coal mechanical equipment. Thirdly, the SGTIN-96 code of EPC coding system is used for the unique identification of single coal mechanical equipment to achieve the conversion between SGTIN and GTIN. Application examples have verified the feasibility of the classification and coding system. To a certain extent, the system solves the problems of confusion classification and coding of coal mechanical equipment information, poor standardization and difficulty in information sharing. Furthermore, the system achieves system compatibility with the global GS1 system, which broadens the circulation of relevant products and technologies in the coal industry.
