Online diagnosis and preventive maintenance system for container cranes based on big data

Abstract

The invention discloses a system for online diagnosis and preventive maintenance of a container crane based on big data. The system comprises a crane equipment layer, a sensor layer, a network layer and a data service layer, wherein the data service layer is further divided into a data analysis and model layer, a data application layer and a business system layer; the crane equipment layer receives operating parameters of the crane; the sensor layer receives sensor signals of key parts of the crane; the network layer transmits the operating parameters and the sensor signals to the data service layer; the data analysis and model layer presets a normal operating model and a fault model of the crane, and compares the operating parameters and the sensor signals with the model, so as to judge the operating state of the crane; the data application layer predicts the operating stable of the crane within a certain period of time in the future according to the operating parameters and the sensor signals, so as to generate a fault early warning; and the business system layer is provided with an external data interface, and outputs data of the data analysis and model layer as well as the data application layer to the outside world.

Description

technical field [0001] The present invention relates to a crane maintenance system, more specifically, to a container crane online diagnosis and preventive maintenance system based on big data. Background technique [0002] The container crane is the main working equipment of the container terminal, and its good condition and efficient work determine the production efficiency and economic benefits of the terminal. At the same time, this type of crane is a large-scale and technically complex handling and handling equipment that integrates mechanical, electrical, hydraulic and computer control technologies. The cost of purchasing a single machine is very high, and maintenance costs are also the main cost of the company's daily operations. Therefore, for the operation and maintenance department of the container terminal, it is the basic work requirement to do a good job in the daily maintenance and maintenance of the crane, to ensure that the crane can be operated at any time a...
