Remote maintenance decision system of engineering machinery and method thereof

Abstract

The invention relates to a remote maintenance decision system of engineering machinery and a method thereof. The system comprises an information acquisition terminal, a client and a maintenance decision center. The information acquisition terminal acquires characteristic parameter information of a part of the engineering machinery in real time. The maintenance decision center comprises a life cycle phase determination module, a part residual life prediction module and a fault diagnosis and maintenance decision function module. The life cycle phase determination module receives the real-time characteristic parameter information and determines a present life cycle phase of the part. The part residual life prediction module carries out residual life prediction on the part at a normal phase or a performance decline phase. The fault diagnosis and maintenance decision function module carries out fault reason diagnosis on the part at a failure phase and provides a maintenance scheme. The client displays a residual life, or a fault reason and the maintenance scheme of the part. According to the system and the method of the invention, the life prediction or the fault diagnosis can be carried out on the part, and remote maintenance is carried out on the engineering machinery.

Description

technical field [0001] The invention relates to the technical field of construction machinery maintenance and fault diagnosis, in particular to a remote maintenance decision-making system and method for construction machinery. Background technique [0002] Construction machinery is the necessary mechanical equipment for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and loading and unloading operations, and various construction projects. Remote maintenance of construction machinery can play an early warning role and reduce maintenance costs. [0003] The existing remote maintenance system of construction machinery is only a data transmission management platform, which only realizes functions such as remote positioning, status monitoring, and maintenance management, and lacks effective analysis and processing of data, especially the lack of real-time information prediction ...

AI Technical Summary

Problems solved by technology

[0003] The existing remote maintenance system of construction machinery is only a data transmission management platform, which only realizes functions such as remote positioning, status monitoring, and maintenance management, and lacks effective analysis and processing of data, especially the lack of real-time information prediction components. Data processing functions such as remaining life, diagnosing component failures, and providing maintenance decisions are difficult to effectively realize the early warning function, determine the timing of maintenance, and provide reasonable maintenance methods, which cannot meet market demand
