Problems solved by technology

At present, the scheduled inspection plan of domestic airlines is still in the stage of manual planning. With the continuous expansion of the fleet size, manual preparation of the scheduled inspection plan is not only cumbersome but also easy to ignore certain constraints, which is not conducive to reasonable arrangement of parking time and determination Maintenance decision making with suitable maintenance bases and high labor costs

Embodiment 1

[0022] figure 1 A flow chart of a method for preparing a regular inspection plan provided by an embodiment of the present invention, specifically including the following steps:

[0023] S110. Collect data of the regular inspection plan, wherein the data of the regular inspection plan at least includes fleet information, time window data of the regular inspection plan, executable bases of the regular inspection task, and available parking time.

[0024] Regular inspection is the regular maintenance work carried out by airlines on aircraft. After a period of flight, aircraft engines and on-board equipment will become loose and corroded due to wear and tear. The quality of hydraulic oil and lubricating oil in aircraft systems will deteriorate. Deterioration and the number will decrease, and it needs to be replaced or replenished. Therefore, after the aircraft has been flying for a period of time, the maintenance personnel must carry out relevant inspections and repairs, find and ...

Embodiment 2

[0033] The embodiment of the present invention also provides a flow chart of preprocessing the data of the regular inspection plan, as a further description of the first embodiment, as shown in figure 2 As shown, step S120 includes:

[0034] S121. Read and collect the scheduled inspection plan data;

[0035] S122. Perform fault data identification on the regular inspection plan data, wherein the fault data identification includes an expectation maximization algorithm and an outlier detection algorithm;

[0036] After collecting the scheduled inspection plan data, carry out fault data identification. Fault data identification is to identify the information in the data that is obviously inconsistent with the actual situation through various logic algorithms. This logic algorithm can be an expectation maximization algorithm or an outlier detection algorithm.

[0037] S123. Repairing the fault data of the regular inspection plan data to obtain repaired regular inspection plan d...

Embodiment 3

[0042] The embodiment of the present invention also provides a flow chart of data mining and analysis of regular inspection plan data, as a further description of the above embodiment, as shown in image 3 As shown, step S130 includes:

[0043] S131. Read high-quality regular inspection plan data.

[0044] S132. Initialize high-quality regular inspection plan data, and convert the high-quality regular inspection plan data into regular inspection plan data in a unified data format.

[0045] The purpose of initialization is to convert different types of data in the data into a unified data format. The regular inspection plan data includes different themes and different data types. Through initialization processing, all data are converted into a unified data format to facilitate data mining. analyze.

[0046] S133. Analyze the regular inspection plan data in a unified data format through data mining to obtain a regular inspection plan information table. Among them, the data mi...

Abstract

The invention discloses an aircraft regular inspection plan making method and device. The aircraft regular inspection plan making method comprises the steps that the regular inspection plan data are acquired, wherein the regular inspection plan data at least include the fleet information, the regular inspection plan time window data, the regular inspection task executable base and the stoppable time; the regular inspection plan data are preprocessed so that the high-quality regular inspection plan data can be obtained; and data mining analysis is performed on the high-quality regular inspection plan data so that a regular inspection plan information table can be obtained. The regular inspection plan information table can be obtained by analyzing various types of regular inspection plan data and data preprocessing and data mining analysis so that the defect of unreliable regular inspection plan information caused by inadequate consideration factors of manually making the regular inspection plan can be overcome and the problem of labor cost caused by manual making can be solved, and thus the pricing plane information table guided maintenance decision can be more efficiently obtained.

Description

technical field [0001] The embodiments of the present invention relate to the field of data processing, in particular to a method and device for preparing and processing an aircraft regular inspection plan. Background technique [0002] The aviation maintenance production plan is a plan formulated by the aviation production management department for how to arrange maintenance tasks. A reasonable maintenance plan can not only ensure that the company completes the maintenance work according to the fixed inspection time limit at all levels stipulated in the maintenance plan, but also ensures the timely completion of various airworthiness instructions, ensures the continuous airworthiness of each aircraft, and scientifically and rationally arranges the echelon use of aircraft. In order to save costs to a greater extent and improve the economic benefits of airlines. [0003] Aircraft inspection plan is subject to maintenance integrity constraints, maintenance inspection interval...
