Abstract

The invention, which belongs to the intersection field of data mining and engineering application, provides a data-mining-based engineering vehicle fault prediction system and prediction method. The fault prediction system comprises a mining fault-related frequent item set module, a decision-making forest establishment module, and a fault prediction module that are connected successively. The mining fault-related frequent item set module preprocesses basic data of an engineering vehicle to obtain a faulty vehicle attribute and acquires a frequent item set through the faulty vehicle attribute;the decision-making forest establishment module carries out data reprocessing, constructs a training set, and forms a decision-making tree and a corresponding decision-making forest and the fault prediction module carries out classification prediction on a fault risk of the engineering vehicle and outputs a result. Therefore, a rule relates to a fault is obtained from lots of irregular engineeringvehicle working condition information; a possible fault is predicted by using the existing engineering vehicle working condition information effectively; and the prediction method is one with fast operation and high efficiency.

Description

technical field [0001] The invention belongs to the intersecting field of data mining and engineering application, and relates to a data mining-based engineering vehicle failure prediction system and a prediction method thereof. Background technique [0002] In real life, a large number of engineering vehicles are needed in various mines and construction sites. Due to long-time work and other reasons, these engineering vehicles are prone to breakdowns, and once a breakdown occurs, factors such as consignment, maintenance, and work delays will also have a greater impact on the entire project. In order to reduce the failure rate of engineering vehicles and thereby reduce engineering losses, there is a great demand to dig out the hidden relationship between the working conditions and faults of engineering vehicles through data mining algorithms, so as to make correct predictions for the state of engineering vehicles. [0003] There are two main requirements for engineering veh...
