Embodiment 1

[0029] figure 1 It shows the flow of the data association method used for aircraft digital maintenance application according to the first embodiment of the present invention. In this embodiment, the association method is performed according to the following steps:

[0030] S101: Acquire the digital model of the first object;

[0031] S102: Store the digital model of the first object;

[0032] S103: Identify at least a part of the digital model of the first object as a hot zone;

[0033] S104: Establish a data table including a correspondence relationship between the hot zone and the determined digital model of the second object corresponding to the hot zone.

[0034] For example, in the JavaEE environment, the content including text and two-dimensional images is extracted from the electronic documents related to aircraft maintenance, the original electronic documents are reconstructed in XML format, and they are saved in a hierarchical structure to obtain the manual structu...

Embodiment 2

[0037] figure 2 shows a second embodiment according to the present invention for use in figure 1 The associated method in implements the flow of the method that exposes the digital model of the second object. In this embodiment, the display method is carried out according to the following steps:

[0038] S201: Obtain the hot zone of the selected digital model of the first object;

[0039] S202: Find the corresponding second object digital model based on the selected hot zone of the first object digital model according to the data table;

[0040] S203: Display the second object digital model corresponding to the selected hot zone of the first object digital model.

[0041] For example, in the JavaEE environment, after the 2D model and the 3D model in the aircraft maintenance manual are associated according to the method in Embodiment 1, the user clicks on the hot spot on the 2D model in the foreground, and the user can obtain the 3D model selected by the user in the backgro...

Embodiment 3

[0044] image 3 A data association device for aircraft digital maintenance application according to a third embodiment of the present invention is shown. In this embodiment, the data association device is realized under the JavaEE environment. First, the first obtaining device 310 obtains the digital model of the first object such as 2D diagram or text from the manual related to aircraft maintenance, and then uses the storage device 320 to store The above-mentioned 2D diagrams or texts, etc. are preferably stored in a hierarchical structure, and then use the identification device 330 to identify at least a part of these 2D diagrams or texts, etc., as hot spots based on the information represented by the above-mentioned 2D diagrams or texts, preferably using the JQuery framework definition hot zone, finally use the corresponding means 340 to determine the corresponding second object digital model such as 3D model or resource file or HTML according to the information represented...

Abstract

The invention relates to a data association method used for airplane digitalization maintenance and application. The association method includes: a first object digital model of information is obtained, wherein the first object digital model of the information is related to the first object digitalization maintenance and application; the first object digital model is stored; based on the information shown by the first object digital model, at least one part of the first object digital model is marked to be a hot area; and according to the information shown in the hot area, a corresponding second object digital model is confirmed, a data list is formed and contains corresponding relation between the confirmed hot area and the second object digital model which corresponds to the hot area, and the second object digital model contains information related to the airplane digitalization maintenance and application. By utilization of the data association method used for the airplane digitalization maintenance and application and a data association device used for the data association method used for the airplane digitalization maintenance and application, relevance and dynamic application between a maintenance manual and a three-dimensional digital model can be established, intuition of a maintenance process is strengthened, and the efficiency and quality of maintenance are improved.

Description

technical field [0001] The invention relates to a data association method and its device, in particular to a data association method and its device for the application of aircraft digital maintenance. Background technique [0002] With the increasing emphasis on comprehensive logistics support for large and complex equipment, digital maintenance technology and related information systems have been greatly developed and applied. For example, in the field of aircraft integrated logistics support, Boeing and Airbus, two major civil aviation giants, have gradually carried out research on digital maintenance systems and developed related systems, mainly composed of failure prediction and status management systems (PHM, Prognostics and Health Management) ), Portable Maintenance Aid (PMA, Portable Maintenance Aid), Interactive Electronic Technical Manual (IETM, Interactive Electronic Technical Manual), remote maintenance system and other key technologies. In practical applications,...
