Abstract

The invention discloses an engineering machinery life-cycle information tracing system. The system comprises an information tracing database used for storing information uploaded from an information system of each phase of a life cycle and performing corresponding storage; an information tracing service system used for receiving and executing information tracing or uploading requests of each phase in the life cycle; a service phase information system based on a mobile hand-held terminal for identifying product individuals of engineering machinery and obtaining and uploading information of a service phase; and a recovery-phase information system based on the mobile hand-held terminal for identifying the product individuals of the engineering machinery and obtaining and uploading recovery evaluation and logistics information. The tracing system and method have the following advantages: product key information from the information system of each phase of the life cycle is stored in the information tracing database in a logic association form; the information tracing database is taken as the only data source, the information tracing service system performs unified management on information tracing service so that information consistency and completeness can be guaranteed, and information redundancy is avoided.

Description

technical field [0001] The invention belongs to the field of construction machinery life cycle information management and the application of the Internet of Things, and in particular relates to a construction machinery life cycle information traceability system and a traceability method. Background technique [0002] A large amount of information related to products, business processes and participants is generated in the whole process of construction machinery products from product design, manufacturing, inspection, sales to user use, maintenance, repair, recycling, remanufacturing, reservice, and scrapping. During the long-term service of the product, the service environment of the product is varied, and there are randomness and uncertainty in maintenance and repair, so the generated information also has dynamic uncertainty. The design information, manufacturing information, service information and user information of construction machinery products are of great significan...
