Description

  The present invention relates to an aircraft maintenance support system that supports aircraft maintenance work, and in particular, a maintenance worker carries an information terminal and receives information necessary for maintenance at the information terminal, or a maintenance result from the information terminal. The present invention relates to an aircraft maintenance support system capable of transmitting information on a server to a server.

  In order to operate an aircraft safely, the state of the aircraft must be maintained appropriately and its airworthiness must be ensured. Therefore, the maintenance performed on the aircraft is necessarily thorough. Here, in the maintenance of aircraft, in addition to the relatively large number of parts compared to other transport machines, the types of on-board equipment are increasing and diversifying, so a complicated system has been made. ing. Therefore, although the contents of aircraft maintenance are relatively complicated compared to other transportation equipment, in addition to this, (1) different aircraft models, parts and mounted equipment differ. Therefore, the items to be maintained (maintenance execution items) are different, and (2) the maintenance date and items are different depending on the flight time even for the same model.

  Such specialities may significantly affect the maintenance of small aircraft (small aircraft, small helicopters, etc.). For example, a small aircraft may be maintained by accommodating a plurality of aircraft in the same hangar. However, even if all of the accommodated aircraft are of the same model, the special characteristics of (2) above are necessary for maintenance. If the model is different, the special feature (1) must also be considered.

  Therefore, in aircraft maintenance, various types of manuals with maintenance details (maintenance dates, items, procedures, etc.) corresponding to each aircraft model and flight time are prepared in advance. An appropriate manual is selected from many types of manuals. In the first place, the number of parts and the number of items that need to be maintained has increased due to the increase in the number of components and equipment, which increases the burden of maintenance for maintenance personnel and makes it cumbersome just to select a specific manual. become. In addition, if a different manual is selected each time and maintenance is performed with different contents each time, the skill level of the maintenance worker cannot be effectively utilized. Therefore, conventionally, there has been a problem that the efficiency of maintenance work is greatly reduced.

  As a technique for dealing with such a problem, for example, Patent Document 1 discloses an aircraft maintenance information support system that generates a maintenance manual that covers work necessary for maintenance.

  Specifically, when a maintenance execution item is notified to an information-related device from a maintenance information device such as a laptop computer, PDA, or wearable PC that is individually carried by a maintenance worker, To scan aircraft maintenance histories and manuals stored in the maintenance information system, collect data required for maintenance, generate maintenance manuals covering the necessary work according to maintenance execution items, Send to maintenance information device.

  According to Patent Document 1, the above-described configuration avoids a maintenance method (represented as “shotgun maintenance” in Patent Document 1) in which related equipment is replaced as needed, and reduces the time and cost required for maintenance. It is disclosed that it can be greatly reduced, and further, it is possible to feed back maintenance status data and to obtain an effect such as being able to cope with a similar problem.

  In addition, for example, Patent Document 2 is not limited to aircraft maintenance, but information necessary for work is acquired when necessary regardless of the storage location of the information, and records of work and inspection are effectively used. A field support system is disclosed that can be used to input work and inspection records on site.

  Specifically, at the time of inspection, the work management server is accessed from a wearable computer (WPC), and the WPC acquires support for the inspection content from the work management server. The worker performs an inspection work while referring to the inspection items displayed on the WPC, and when an abnormality is found during the inspection, the work is transmitted to the work management server. When all the inspection items are inspected, the work report is created on the spot by WPC and transmitted to the work management server as the inspection ends.

  According to Patent Document 2, with the above configuration, various information such as drawings, tables, and design data of the upstream system can be referred to in real time on the site, and conversely, on-site information and maintenance inspection records can be referred to in real time. It is disclosed that since it can be digitized and sent to an upstream system, a great effect can be obtained in improving work quality, reducing the number of workers, shortening the construction period, and reducing costs.

  By the way, in a support system in which a maintenance worker carries an information terminal device and transmits / receives (communications) information between the information terminal device and an information management device (such as a server) to support maintenance work, a plurality of types of data If information in which formats are mixed or information having a large amount of data is communicated, the operability or convenience of the information terminal device may be lowered for the maintenance worker.

  For example, the information terminal device is basically configured to display information using a web browser (Internet browser). Here, since various manuals referred to during maintenance work often cover multiple pages, these manuals are data formats that allow multiple pages to be combined into a single file, such as PDF (Portable Document Format). It is often a file (hereinafter referred to as “multi-page format” for convenience of explanation).

  Such a multi-page format file cannot be displayed by a general web browser, and a specific viewer must be activated. However, if the software is frequently switched to refer to the manual during maintenance work, the convenience and operability of the information terminal device will be reduced for the maintenance worker.

  Further, when referring to a multi-page format file, all the files consisting of a plurality of pages are downloaded from the information management device to the information terminal device. Therefore, even if it is desired to refer to only a part of the manual, the entire manual is downloaded, so that the information terminal apparatus receives all information other than the information that is originally required. Therefore, there is a possibility that the reception time (download time) becomes relatively long, or the amount of data to be received becomes relatively large and the memory capacity of the information terminal device becomes insufficient. As a result, the convenience and operability of the information terminal device are lowered for the maintenance worker.

  Furthermore, the data format when the maintenance result is transmitted to the information management device also affects the convenience and operability of the information terminal device.

  For example, the maintenance result usually needs to be processed into a report in a predetermined format, but such a report is often created by general application software (spreadsheet software, word processor, etc.). . If the application software is installed in the information terminal device, software other than the web browser is activated at the time of input, and a large memory capacity is used. Further, since the file created by the application software has a larger data amount than a file of a highly versatile data format such as text format or CSV format, the transmission time from the information terminal device to the information management device is also long. Relatively long.

  Here, since the technique disclosed in Patent Document 1 is configured such that a necessary maintenance manual is appropriately generated and transmitted to the maintenance information device, unnecessary information is theoretically included in the maintenance manual transmitted and received. It is determined that the amount of data does not increase. However, for example, in the case of maintenance information devices as hardware, if the storage capacity is limited, the minimum necessary data is acquired, and when the maintenance manual to be referred to changes, a continuous maintenance manual is updated. Although acquisition is mentioned, there is almost no mention about the data format, data amount, etc. of the maintenance manual.

  Further, the technology disclosed in Patent Document 2 only discloses a configuration for simply reading data from the work management server. Similar to Patent Document 1, the data format, data amount, and the like of data acquired as an inspection item are disclosed. Has not been studied at all.

  As described above, for example, in a situation where a plurality of small aircraft are stored in the same hangar, there is a possibility that individual maintenance is required for each aircraft. Therefore, it is extremely inefficient for maintenance workers to create a report by referring to the manual for each aircraft.

  In addition, even when the maintenance worker supports the maintenance work by carrying the information terminal device and communicating with the information management device, if the data format and the amount of data transmitted and received are not sufficiently examined, the above-mentioned As described above, the convenience and operability of the information terminal device are reduced. Therefore, it is impossible to avoid complications such as receiving manuals with different data formats each time a maintenance work for each machine and starting up a specific viewer, and the maintenance work cannot be made sufficiently efficient.

  The present invention has been made to solve such a problem, and includes an information terminal device carried by a maintenance worker and an information management device capable of transmitting and receiving between the information terminal device. An object of the maintenance support system is to improve the convenience and operability of the information terminal device and further improve the maintenance efficiency.

In order to solve the above-described problem, an aircraft maintenance support system according to the present invention is provided between an information terminal device that is carried by an operator who performs aircraft maintenance work and includes an input unit and a display unit, and the information terminal device. A maintenance data storage area for storing a plurality of maintenance data including maintenance execution items, which is data used for maintenance of the aircraft, and the aircraft A maintenance data storage unit having a reference data storage area for storing reference data associated with specific maintenance data, and a data group stored in the maintenance data storage unit, the information terminal Specific that collects specific maintenance data that matches the maintenance conditions input from the device and specific reference data associated with the specific maintenance data A display data generation unit that generates display data in a format that can be displayed on the information terminal device from the collected specific maintenance data and the specific reference data. The generation unit has a configuration in which the single maintenance execution item and the specific reference data included in the specific maintenance data are collectively displayed on the information terminal device as a page screen that is a display screen for one page. As described above, when the display data is generated and the specific maintenance data and the specific reference data have different data formats, the display data generation unit includes a link to the specific reference data, and The display data is generated so that at least one of the specific reference data incorporated on the screen is displayed on the page screen .

  According to the above configuration, the information management device generates display data using maintenance data used for aircraft maintenance and reference data referred to for maintenance work, and the information terminal device The display data stored in the shared storage unit is displayed. The display data is configured such that one page screen is displayed for each maintenance execution item.

  Thereby, the information terminal device can appropriately read data generated for display (display data) for each maintenance execution item from the information management device. Therefore, the maintenance operator can read and browse necessary information from the information management device when necessary according to the contents of the maintenance, and even if the maintenance data and the reference data are in different data formats, Since it is displayed as a single page screen, it can be browsed without switching a plurality of software on the information terminal device.

  As a result, for example, even if multiple aircraft are stored in the same hangar, and the models of each aircraft are different or the flight time is different, the maintenance operator needs the necessary maintenance data and references for each aircraft. The data can be easily acquired from the information management device as needed, and the acquired maintenance data and reference data can be browsed by the information terminal device in a state that does not require complicated operations. Therefore, the convenience and operability of the information terminal device can be further improved than before, and the maintenance efficiency can be further improved.

Furthermore, according to the said structure, display data are produced | generated so that reference data may be incorporated in the screen comprised on the basis of the data format of maintenance data, or it may be referred with another screen. Therefore, in the information terminal device, it is not necessary to switch a plurality of software and browse the page screen, and the convenience and operability can be further improved.

And an image data conversion unit that inputs a command to the effect that the file image data has been generated to the display data generation unit, wherein the display data generation unit includes the specific reference data If it is a multi-page file, a link to the file image data is displayed on the page screen so that More preferably, it is a configuration that generates display data, and the image data converter assigns page identification data to each page obtained by dividing the multi-page file, converts it into the file image data, and displays the display data. It is more preferable that the data generating unit is configured to generate the display data so that the link is displayed only for the page corresponding to the specific maintenance data in the file image data.

  In the aircraft maintenance support system, communication is performed only when a maintenance worker operates the information terminal device, and communication is blocked when no operation is performed. Thereby, inadvertent electromagnetic influence on aircraft equipment can be prevented.

  In addition, according to the above-described configuration, not only can the multi-page file be converted to be viewable on the page screen, but page identification data may be assigned to each page, so that the multi-page file is included in the multi-page file. Display data can be generated so that only pages necessary for maintenance are referred to. Thereby, the convenience and operability of the information terminal device can be further improved.

  In the aircraft maintenance support system, the reference data stored in the maintenance data storage unit includes raster-format graphic image data, and the display data generation unit includes the specific reference data as the graphic image data. If so, it is preferable that the display data is generated so that the graphic image data is incorporated on the screen, and the graphic image data includes an aircraft that highlights a location corresponding to the maintenance execution item. An overall view, an enlarged photograph of a location corresponding to the maintenance execution item, or both can be given.

  According to the above-described configuration, necessary image data (for example, the overall view of the aircraft or the enlarged photograph) can be displayed on the page screen, so that the maintenance worker can simultaneously check the image data together with the maintenance data. Therefore, the convenience and operability of the information terminal device can be further improved.

  In the aircraft maintenance support system, a moving image file is included in the reference data stored in the maintenance data storage unit, and the display data generation unit, if the specific reference data is the moving image file, The display data is preferably generated so that a link to a moving image file is displayed on the page screen.

  According to the above configuration, it is difficult to display the moving image file at the same time as the maintenance execution item on the page screen. By configuring the video file so that it can be referred to by a link, the convenience and operability of the information terminal device can be improved it can.

  In the aircraft maintenance support system, the display data generation unit further generates link display data that is a screen dedicated to the link to the specific reference data, and the page screen includes a link to the link dedicated screen. It is more preferable if the display data is generated so that is displayed.

  According to the above configuration, when there is a lot of specific reference data that is preferably referred to by a link, the specific reference data is configured to be linked together on the link dedicated screen, and the link dedicated screen can be linked from each page screen. It will be configured as follows. Therefore, only information necessary for maintenance can be appropriately displayed on each page screen, so that the convenience and operability of the information terminal device can be further improved.

  In the aircraft maintenance support system, in addition to the configuration, the information management device generates a maintenance result transmitted from the information terminal device as maintenance result data in the same format as the maintenance data, and stores the maintenance data. It is preferable that the apparatus further includes a maintenance result generation unit to be stored in the storage unit, and the maintenance data storage unit further includes a maintenance result data storage area for storing the maintenance result data.

  According to the said structure, a maintenance result can be transmitted to an information management apparatus from an information terminal device, and maintenance result data can be produced | generated and memorize | stored in an information management apparatus. Therefore, not only maintenance support but also management of maintenance results can be supported.

  Although the specific configuration of the information terminal device used in the aircraft maintenance support system is not particularly limited, for example, as the information terminal device, a wearable portable information terminal device can be suitably used.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following description, the same or corresponding elements are denoted by the same reference symbols throughout the drawings, and redundant description thereof is omitted.

[Configuration of aircraft maintenance support system]
First, the configuration of the aircraft maintenance support system according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing an example of the configuration of an aircraft maintenance support system according to an embodiment of the present invention. FIG. 2 is a schematic diagram showing an example of a state in which a maintenance operator is equipped with a wearable portable information terminal device, which is a preferred example of an information terminal device included in the aircraft maintenance support system shown in FIG.

  As shown in FIG. 1, an aircraft maintenance support system 10 (hereinafter, abbreviated as “support system” as appropriate) according to the present embodiment includes at least an information management device 20 and an information terminal device 40. The support system 10 according to the present embodiment has a plurality of information terminal devices 40 (three information terminal devices 40 are schematically shown in FIG. 1), but may be one. That is, the support system 10 according to the present embodiment only needs to include one or more information terminal devices 40. In addition, the information management device 20 and the information terminal device 40 can communicate with each other wirelessly as indicated by a dotted line in the figure. This point will be described later.

  The information management device 20 includes an input / output unit 21, a maintenance data storage unit 22, a calculation unit 31, a calculation storage unit 32, a specific data collection unit 33, a display data generation unit 34, an image data conversion unit 35, a shared storage unit 23, A maintenance result generation unit 36 and a management-side wireless communication unit 24 are provided.

  The input / output unit 21 includes a known input unit that inputs various information to the information management apparatus 20 and a known output unit that outputs various information from the information management apparatus 20. In FIG. 1, for convenience of explanation, a single block is shown. However, in actuality, it is composed of at least one input unit and output unit, and furthermore, the same or different types of input units or output units are provided. A plurality may be included.

  The specific input unit is not particularly limited. For example, various input devices or input devices known in the field of personal computers (PCs) such as a keyboard, a mouse, and a tablet are used. In this embodiment, a USB port or the like is used. The external connection terminal can also be regarded as an input section. As a result, various types of information can be input directly from the external information processing apparatus to the information management apparatus 20.

  Similarly, the specific output unit is not particularly limited. For example, various display devices that output a soft copy of information, such as a liquid crystal panel display, and various image formations that output a hard copy of information, such as an ink jet printer or a laser printer. A device is used. Similarly to the input unit, it can be regarded as an external connection terminal output unit such as a USB port. As a result, various information can be directly output from the information management apparatus 20 to the external information processing apparatus.

  The maintenance data storage unit 22 is a storage device that stores various types of information used or referenced for aircraft maintenance as data (electronic information). In this embodiment, the maintenance data storage area 22a and the reference data storage area are stored. 22b and a maintenance result data storage area 22c. The specific configuration of the maintenance data storage unit 22 is not particularly limited, and a known storage device such as a hard disk is preferably used. Further, the maintenance data storage unit 22 does not have to be a single unit, and may include a plurality of storage devices.

  The maintenance data stored in the maintenance data storage area 22a is data including maintenance execution items that are the most basic information used for aircraft maintenance. The maintenance execution items differ depending on the specific contents of the maintenance to be performed, and are not particularly limited. The maintenance data is stored as a CSV file in the present embodiment, but may be a text file. Aircraft maintenance includes daily or periodic inspections, overhaul, various inspections, parts replacement, wear or repair of damaged parts, etc. In this embodiment, various inspections during periodic inspections are exemplified. The configuration of the support system 10 will be described.

  The reference data stored in the reference data storage area 22b is defined as data associated with specific maintenance data. For example, if the aircraft to be serviced is a small rotary wing aircraft (for example, a small helicopter) and the aircraft is to be regularly inspected or inspected, the inspection or inspection manual for the aircraft, the specifications of the aircraft, etc. are described. If it is a manual, past inspection results, or a complicated inspection, a moving picture material specifically showing the procedure of the inspection may be mentioned. Of these, inspection or inspection manuals, manuals, etc. are stored as PDF files, and past inspection results are stored as PDF files if they are in report format, and JPEG files, BMP files, etc., if they are photographs. It is stored as raster format or vector format image data such as a DXF file or SVG file, and in the case of moving image material, it is stored as moving image data such as an MPEG file (for example, an MP4 file).

  The maintenance data and reference data are used by the display data generation unit 34 to generate display data, as will be described later. Further, if the reference data is a PDF file or the like, it is converted into an image data format such as JPEG by the image data conversion unit 35 and used as display data if necessary.

  The maintenance result data stored in the maintenance result data storage area 22c is the maintenance result transmitted from the information terminal device 40, and is stored in the same format as the maintenance data (in the present embodiment, a CSV file). As will be described later, the maintenance result data is compiled in a predetermined format by comparing maintenance results appropriately transmitted from the information terminal device 40 with individual maintenance execution items, and is generated by the maintenance result generation unit 36. The

  The calculation unit 31 performs calculations related to the overall operation of the information management apparatus 20, and the calculation storage unit 32 stores various programs for calculations executed by the calculation unit 31. The calculation unit 31 and the calculation storage unit 32 are configured by, for example, a microcomputer CPU and an internal memory, respectively.

  The specific data collection unit 33 has a configuration for collecting data that meets the maintenance conditions input from the information terminal device 40 from the data group stored in the maintenance data storage unit 22. Specifically, for example, if a specific model and flight time of an aircraft are input from the information terminal device 40, maintenance data including maintenance execution items corresponding to the model and flight time, and the maintenance data are associated with the maintenance data. Collect reference data. For convenience of explanation, maintenance data that meets the input maintenance conditions is referred to as “specific maintenance data”, and reference data associated with the “specific maintenance data” is referred to as “specific reference data”.

  The specific data collection unit 33 also has a configuration in which the data format of the specific reference data included in the collected data group is determined and input to the display data generation unit 34. This point will be described later. Further, the specific data collection unit 33 is configured to input the collected specific maintenance data to the maintenance result generation unit 36. This is because the maintenance result generator 36 uses the specific maintenance data to generate maintenance result data in a predetermined format, as will be described later.

  The display data generation unit 34 generates display data in a format that can be displayed by the information terminal device 40 from the specific maintenance data and the specific reference data collected by the specific data collection unit 33. Specifically, in the present embodiment, since the information terminal device 40 is configured to display information by a web browser, the display data generation unit 34 generates specific maintenance data, which is a CSV file, as HTML or the like. To an HTML document file created in the markup language. In addition, the specific reference data is incorporated into an HTML document file according to the data format, or link data to the specific reference data is added to the HTML document.

  Here, as will be described later, the display data generation unit 34 displays the display data so that the single maintenance execution item included in the specific maintenance data is displayed on the information terminal device 40 as a single page screen. It has a configuration to generate. In addition, in the state where the display data is displayed as a single page screen, specific reference data can also be displayed. The “page screen” defined in the present embodiment is a minimum unit screen displayed as a display screen for one page on the information terminal device 40. The “page screen” includes a plurality of maintenance execution items. Only one is displayed, and reference data related to this is also displayed.

  Further, as described above, the display data generation unit 34 receives the determination result of the data format of the specific reference data from the specific data collection unit 33, and assigns various identifiers to the display data based on the determination result. It has a configuration. Specifically, when the specific maintenance data and the specific reference data have the same data format in the specific data collection unit 33, there is no particular influence on the generation of the display data. Is a CSV file and the specific reference data is a JPEG file such as a photograph, the display data generation unit 34 gives a tag (identifier) for incorporating the JEPG file into the screen to the HTML document file.

  Note that raster format graphic image data including the JPEG format can be incorporated on the screen by tags in HTML document files, and thus the tag serves as an identifier of specific reference data. Also, if the specific reference data is a PDF file or a moving image file, the HTML document file cannot be incorporated on the screen like graphic image data, so the display data generation unit 34 creates a link. Become. Therefore, this link tag becomes the identifier of the specific reference data.

  In the present embodiment, the image data conversion unit 35 is configured to convert the specific reference data into a data format that can be displayed by a web browser if the specific reference data is a data format that cannot be directly displayed by a web browser. Specifically, as described above, a manual or a manual is stored in the reference data storage area 22b as a PDF file. This PDF file cannot be browsed directly by a web browser, and a specific viewer must be activated. Therefore, the image data conversion unit 35 divides the PDF file into pages and converts them into JPEG files.

  In the present embodiment, a data format file that can be configured as a single file with a plurality of pages, such as a PDF file, is referred to as a “multi-page file” for convenience of explanation. Data formats corresponding to multi-page files include TIFF (Tagged Image File Format) files, DocuWorks (registered trademark) data files, and the like in addition to the PDF. If the above-mentioned various multi-page files are included in the specific reference data, the image data conversion unit 35 divides the files into pages and converts them into a data format that can be viewed with a web browser.

  Here, the data format that can be browsed by the web browser is not limited to the JPEG file, but may be another raster format that can be displayed by the web browser, such as a BMP file or a GIF file. That is, if the data of each divided page is converted into image data in a compressed image format, it can be viewed with a web browser in most cases. For convenience of explanation, image data generated by dividing and converting a multi-page file is referred to as “file image data” and is distinguished from “image data” as a general noun.

  Further, when the image data conversion unit 35 generates the file image data by dividing and converting the multi-page file, the image data conversion unit 35 inputs an instruction to the effect that the file image data has been generated to the display data generation unit 34. . Based on the input command, the display data generation unit 34 assigns link data to the HTML document file so that a link to the file image data is displayed on the page screen.

  Here, if the multi-page file is only one page, only one file image data is generated. However, since the multi-page file is usually composed of a plurality of pages, in this embodiment, the image data conversion unit 35 preferably has a configuration in which page identification data is given to each divided page and then converted into file image data. In addition, when the display data generating unit 34 generates display data, the display data generating unit 34 is configured to add link data so that only the file image data of the page corresponding to the specific maintenance data is displayed. It is preferable.

  For example, if the reference image data is a description explaining the specifications of the entire aircraft, and the maintenance content is an operation for inspecting only the cockpit of the aircraft, what should be referred to in the above description usually relates to the cockpit There are only places. Therefore, the display data generation unit 34 generates display data so that a link is displayed only for file image data corresponding to a page related to a cockpit. In this case, if an identifier is included in the file data of the manual according to the described contents, when the image data conversion unit 35 generates file image data for each page, the identifier is identified by page identification. What is necessary is just to give as data. As a result, the display data generation unit 34 can create link data of the corresponding page from the identifier and assign it to the HTML document file.

  The shared storage unit 23 is a storage device that stores the display data generated by the display data generation unit 34 as a shared state that can be displayed on the information terminal device 40. That is, if the display data is an HTML document file as described above, the display data is uploaded to the shared storage unit 23 in the same manner as a method of publishing a so-called home page on the Internet. Thereby, the information terminal device 40 reads necessary maintenance data and reference data from the shared storage unit 23 by transmitting the maintenance conditions to the information management device 20 so as to browse the homepage by inputting the URL. it can.

  If a plurality of specific maintenance data is collected by the specific data collection unit 33 from the maintenance conditions transmitted from the information terminal device 40, a plurality of display data are also generated by the display data generation unit 34. That is, the display data generation unit 34 is configured to generate one display data from one specific maintenance data. Therefore, a plurality of display data is also stored in the shared storage unit 23, and the information terminal device 40 displays each of the plurality of display data as a single page screen. Here, as described above, if the page identification data is given by the image data conversion unit 35, the plurality of display data constitute a continuous display data group in the order corresponding to the maintenance order. Become. When the information terminal device 40 reads the display data page by page from one display data group, a plurality of page screens are displayed successively in the order of predetermined maintenance execution items. Therefore, these continuous plural page screens constitute a single “maintenance manual”.

  The shared storage unit 23 may be configured to store not only display data but also file image data generated by the image data conversion unit 35. With this configuration, since the display data and the file image data are stored in the same hierarchy, when displaying the linked reference data on the page screen displayed on the information terminal device 40, The speed of display can be secured.

  Here, the storage of the display data and the file image data in the shared storage unit 23 may be stored from the display data generation unit 34 and the image data conversion unit 35, respectively, as shown in FIG. The file image data generated by the image data conversion unit 35 is input to the display data generation unit 34. The display data generation unit 34 collects the display data and the file image data into one folder, and then stores them in a shared storage. The structure stored in the part 23 may be sufficient, and the structure stored by the calculating part 31 may be sufficient.

  The specific configuration of the shared storage unit 23 is not particularly limited, and a known storage device such as a hard disk is preferably used. Similarly to the maintenance data storage unit 22, the storage data storage unit 22 does not have to be a single storage device, and may be configured by a plurality of storage devices.

[Operation of aircraft maintenance support system]
Next, operation | movement of the assistance system 10 which concerns on this Embodiment is demonstrated with reference to FIG. 3 thru | or FIG. FIG. 3 is a schematic diagram schematically showing an example of a specific configuration when the support system 10 according to the embodiment is used for maintenance of a small rotary wing aircraft. FIG. 4 is a flowchart showing an example of the operation of the support system 10 according to the present embodiment. FIGS. 5A to 5C are diagrams illustrating an example of the configuration of each page screen that is displayed from when the information terminal device 40 included in the support system 10 is started until maintenance content is selected. FIG. 6 is a diagram illustrating an example of a configuration of a page screen on which maintenance data is displayed when maintenance work is performed using the information terminal device 40. FIGS. 7A and 7B are diagrams illustrating an example of a configuration of a page screen on which reference data is displayed, which is switched from a page screen on which maintenance data is displayed.

  Although the support system 10 according to the present embodiment can be widely used in the field of aircraft maintenance, for example, as shown in FIG. 3, a situation where a plurality of small aircraft 80 are stored in a single hangar 70. Are particularly preferably used. In the example shown in FIG. 3, a small rotary wing aircraft 80 (specifically, a small helicopter) is illustrated as an example of a small aircraft, but of course, the present invention is not limited to this, and other types of small aircraft may be used. .

  Most of the hangar 70 schematically shown in FIG. 3 is a parking area 71. In addition, a maintenance office 72 is located at the lower right portion in the figure, and the left side in the figure. The work area 73 is located at this point. The work area 73 is composed of a work space 74 surrounded by a dotted line in the figure and a plurality of parts shelves 75 installed.

  In the parking area 71, small rotary wing aircraft 80 are parked (10 in the example shown in FIG. 3), and a plurality of maintenance workers 91 (4 in the example shown in FIG. 3) perform maintenance work. Yes. Further, the maintenance worker 91 moves between the parking area 71 and the work area 73 as necessary (in the example shown in FIG. 3, one maintenance worker 91 is located in the work area 73). . The maintenance worker 91 wears the information terminal device 40 that is composed of a wearable PC. In FIG. 3, the information terminal device 40 is schematically illustrated by painting a part of the arm of the icon indicating the maintenance worker 91 in black.

  In the maintenance office 72, the information management device 20 constituting the support system 10 is installed, and the maintenance manager 92 manages the information management device 20. Bidirectional wireless communication is performed between the management-side wireless communication unit 24 (shown as an icon of a wireless LAN router in FIG. 3) and the information terminal device 40 provided in the information management device 20. Note that in FIG. 3, the two-way wireless communication is indicated by arrows written in the vicinity of the information terminal device 40.

  An example of a specific operation of the support system 10 according to the present embodiment in the hangar 70 shown in FIG. 3 will be described with reference to the screen display of the information terminal device 40 based on the flowchart shown in FIG.

  First, in the information management device 20, the maintenance manager 92 or the maintenance worker 91 creates maintenance data including maintenance execution items in advance as a CSV file and stores it in the maintenance data storage unit 22 (step S201). On the other hand, since the information terminal device 40 is activated when the maintenance worker 91 turns on the power, for example, as shown in FIG. 5A, in the touch panel unit 41, the initial stage where the maintenance worker 91 is registered. A screen 401 is displayed.

  In the example shown in FIG. 5A, three maintenance workers 91 “Sato”, “Suzuki”, and “Takahashi” have been registered, and a face photograph 411 of each maintenance worker 91 (a person painted black) An icon) is also displayed. These face photographs 411 also function as screen switching keys on the touch panel unit 41. By operating this, the screen is switched to the menu screen 402 shown in FIG. In addition, on the initial screen 401, a guest image 412 (illustrated by a white person icon) using an icon image or the like is displayed so that an unregistered maintenance worker 91 can use the information terminal device 40. .

  For example, if the maintenance worker 91 is “Sato”, the menu screen 402 shown in FIG. 5B is displayed by operating the face photo 411 of Mr. Sato. Any one of the screen switching keys displayed on the menu screen 402 is operated. In the configuration shown in FIG. 5B, a maintenance execution key 413 described as “Perform maintenance” and a material reference key 414 described as “Material list” are displayed, and a menu screen 402 is displayed. A back key 415 that displays “Back” is displayed at the upper left portion of FIG.

  When the maintenance execution key 413 is operated, a maintenance manual screen 403 shown in FIG. Further, if the material reference key 414 is operated, the material screen is displayed although not shown. If the back key 415 is operated, the screen returns to the initial screen 401 shown in FIG.

  The maintenance manual screen 403 is a maintenance manual that can be used by each of the maintenance workers 91 (as described above, a plurality of page screen groups that can be displayed continuously for each maintenance execution item). File names 421a and 421b are displayed. In the example shown in FIG. 5 (c), “ABC type rotary wing aircraft maintenance guidelines.csv” (file name 421a) and “DEF small aircraft maintenance guidelines.csv” (file name 421b) are displayed. . These file names 421a and 421b are maintenance manual display keys, respectively, and by operating either one, the corresponding maintenance manual is displayed.

  In the flowchart shown in FIG. 4, after the initial screen 401 shown in FIG. 5A is displayed, the maintenance manual screen 403 shown in FIG. 5C is displayed, and the file names 421a and 421b are operated. Is displayed as a single predefined processing step “maintenance worker / menu / maintenance manual selection” (step S401). Since this processing step is the same as the normal screen switching control, the description of the specific processing is omitted.

  In the present embodiment, since the small aircraft to be serviced is the small rotary wing aircraft 80, when the maintenance worker 91 operates the file name 421a shown in FIG. 5C, the information terminal device 40 changes to the information management device 20. On the other hand, display data is required. Therefore, in the information management apparatus 20, the specific data collection unit 33 collects specific maintenance data and specific reference data from the maintenance data storage unit 22 (step S202). Specifically, since the maintenance target is an ABC type rotary wing aircraft, this model corresponds to the maintenance conditions. Therefore, the specific data collecting unit 33 collects maintenance data including maintenance execution items related to the model as “specific maintenance data” from the maintenance data storage area 22a, and also refers to the reference data associated with the specific maintenance data as “specific reference data”. Is collected from the reference data storage area 22b.

  Here, the specific data collection unit 33 determines whether or not the collected specific reference data includes a file in a data format that cannot be directly displayed by the web browser (described as “browser non-displayable file” in FIG. 4). Is determined (step S203). If the corresponding file is included (YES in step S203), it is determined whether the multi-page file is included in the corresponding file (step S204). If a multi-page file is included, the corresponding file is input to the image data conversion unit 35. The image data conversion unit 35 divides the multi-page file into pages and converts it into file image data such as a JPEG file. Conversion is performed (step S205).

  Here, regardless of whether or not the file is a multi-page file, if the specific reference data includes a file in a data format that cannot be directly displayed by the web browser, the specific data collection unit 33 displays the determination result to that effect. The data is input to the data generation unit 34, and the display data generation unit 34 creates link data to the corresponding specific reference data (step S206).

  On the other hand, if any specific reference data can be displayed by the web browser (NO in step S203), the specific data collection unit 33 inputs the collected data group to the display data generation unit 34 and displays it. The data generation unit 34 generates display data for each maintenance execution item included in the maintenance data and stores it in the shared storage unit 23 (step S207). If a file that is in a data format that cannot be directly displayed on the web browser but is not a multi-page file is included (NO in step S204), the specific data collection unit 33 displays the determination result to that effect as the display data generation unit 34. The display data generation unit 34 creates link data to the corresponding specific reference data (step S206).

  As described above, when the display data is stored in the shared storage unit 23 of the information management device 20, the information terminal device 40 reads the display data and displays a page screen for each maintenance execution item (step S402). . For example, as shown in FIG. 6, on the page screen for each maintenance execution item, that is, the maintenance work screen 404, the maintenance execution item 430 is displayed on the right side toward the center of the screen, and the lower right side toward the screen. Result input keys 422a to 422d and screen switching keys 418a and 418b are displayed at the locations. In addition, an aircraft maintenance map 431 that schematically shows the entire small rotary wing aircraft 80 that is a maintenance target is displayed at a lower left side of the screen. Further, an enlarged photograph (maintenance part enlarged photograph) 432 of a part corresponding to the maintenance execution item 430 is displayed beside the maintenance execution item 430, that is, at a position closer to the left in the center of the screen. Further, the name of the maintenance worker 91 (“Sato”) and the material link key 416 are displayed on the left side toward the upper side of the screen, and the end key 417 is displayed on the right side.

  The screen switching key 418a is a key for switching to the previous page screen (previous maintenance execution item) in the maintenance manual, and has substantially the same function as the back key 415. The screen switching key 418b is a key for switching to the next page screen (next maintenance execution item) in the maintenance manual.

The result input keys 422a to 422d are keys for inputting the result of maintenance performed by the maintenance worker and transmitting the result to the information management apparatus 20 as maintenance result data in a narrow sense. The result input key 422a is a key for inputting a result that the displayed maintenance execution item 430 is normal and OK, and the result input key 422b is a result that the maintenance execution item 430 is confirmed to be abnormal and is NG. The result input key 422c is a key for clearing the erroneously input result, and the result input key 422d is switched to a memo input screen (not shown) by operating this key. The memo input screen has a configuration in which memos such as caution points, observation points, special notes, etc. can be entered regarding the result of the maintenance performed on the displayed maintenance execution item 430.

  The aircraft maintenance map 431 highlights not only the overall view but also the portion corresponding to the maintenance execution item displayed on the page screen in the small rotary wing aircraft 80 to be maintained. Thus, the graphic image data makes it easier for the maintenance worker 91 to perform the maintenance work. The aircraft maintenance map 431 corresponds to specific reference data, and is displayed by being incorporated in the display data with an identifier (an HTML tag that incorporates an image file on the screen).

  The maintenance location enlarged photograph 432 enlarges and displays a photograph actually taken at a location corresponding to the maintenance execution item displayed on the page screen so that the maintenance worker 91 can easily perform maintenance work. Graphic image data for This maintenance location enlarged photograph 432 also corresponds to the specific reference data, and is displayed by being incorporated in the display data by an identifier (an HTML tag that incorporates an image file on the screen).

  The document link key 416 is a key for switching to a “link dedicated screen” for linking to specific reference data that is a file in a data format that cannot be directly displayed by a web browser, and it can be said that the key itself is a link. . The “link dedicated screen” will be described later.

  The end key 417 is a key for ending the display of the displayed series of maintenance manuals. Although not shown, operating this key displays a screen for shutting down the information terminal device 40. . In this screen, for example, a list of maintenance results may be displayed.

  The maintenance work screen 404 displayed in FIG. 6 displays the third item in the maintenance manual having five maintenance execution items. Therefore, “inspection (3/5)” is displayed in the upper center of the maintenance work screen 404.

  When the material link key 416 is operated from the maintenance work screen 404, as shown in FIG. 7A, a material list screen 405, which is a dedicated link screen, is displayed. In this example, a list of materials referred to in the maintenance manual, that is, specific reference data is displayed as a link. In the example shown in FIG. 7A, three file names 423a to 423c are displayed, and each of the file names 423a to 423c is a material display key (reference data link). By operating 423a, as shown in FIG. 7 (b), the material “ABC type rotary wing aircraft inspection procedure” is displayed.

  Here, in the file name 423a, it is displayed that the material is a PDF file, but the material shown in FIG. 7B is not displayed as a PDF file, but is displayed as, for example, a JPEG file. ing. That is, in this embodiment, as described above, a multi-page file such as a PDF file is converted into file image data such as a JPEG file for each page. Therefore, the display of the material shown in FIG. 7B is not displayed after the PDF viewer is started, but the JPEG file is displayed while the web browser is started. This screen is returned to the material list screen 405 shown in FIG. 7A by operating a return key 419 displayed at the upper left portion of the screen shown in FIG. 7B.

  Furthermore, in the present embodiment, as described above, when the image data conversion unit 35 generates a JPEG file for each page from the PDF file, page identification data is added to the JPEG file. Therefore, for example, if the number of pages of the material of the file name 423a is large and the pages that can be referred to in the corresponding maintenance execution item are specified as several pages, it is shown in FIG. The file name 423a may be linked to only the above-mentioned several pages. As a result, the maintenance worker 91 can browse only necessary portions of the material, and therefore the efficiency of the maintenance work can be further improved.

  Further, in the material list screen 405 shown in FIG. 7A, “50 hours inspection NG spot photo.jpg” (file name 423b) and “inspection device operation procedure (specific reference data)” (Moving image) .mp4 "(file name 423c). None of these are multi-page files, but they are not necessarily displayed on the maintenance work screen 404 (photo file with the file name 423b) or cannot be directly displayed in the same data format (moving image file with the file name 423c). Therefore, it is linked on the material list screen 405.

  The screens shown in FIGS. 7A and 7B are displayed as a single defined processing step “reference data display” (step S403) in the flowchart shown in FIG. In this processing step, as shown in FIG. 4, reference data is requested from the information terminal device 40 to the information management device 20 in the same manner as the processing for displaying the page screen for each maintenance execution item (shown in FIG. 7A). On the other hand, since control is performed so that the reference data is read from the information management device 20 to the information terminal device 40, description of the specific processing is omitted.

  Then, on the maintenance work screen 404 shown in FIG. 6, the maintenance worker 91 checks a part corresponding to the maintenance execution item, determines whether it is OK or NG, operates the result input keys 422a to 422d, and performs maintenance. The result is input to the information terminal device 40 (step S404). As a result, the data is transmitted from the information terminal device 40 to the information management device 20 together with the data accompanying the maintenance result data in a narrow sense, so in the information management device 20, the maintenance result is stored in the CVS file by the maintenance result generation unit 36 (step S208). ).

  Here, the accompanying data transmitted from the information terminal device 40 to the information management device 20 includes the identification information and time information of the maintenance worker 91, as described above. These accompanying data can be used when generating maintenance result data in a broad sense from maintenance result data in a narrow sense and creating a report from the maintenance result data in a broad sense. Therefore, the maintenance worker 91 can create a maintenance report only by performing the maintenance work.

  Thereafter, the information management device 20 determines whether or not the end key 417 shown in FIG. 6 has been operated, that is, whether or not the maintenance is finished (step S405). If not finished (NO in step S405), the next The processing until the maintenance work screen 404 of the maintenance execution item is displayed and the maintenance result is input is repeated (steps S402 to S404). On the other hand, if completed (YES in step S405), a maintenance end command is transmitted from the information terminal device 40 to the information management device 20, so that in the information management device 20, the maintenance result generating unit 36 is a CSV file. Maintenance result data is generated and stored in the maintenance data storage unit 22. Thus, the control of the support system 10 ends.

  Here, in the present embodiment, maintenance data and maintenance result data in a broad sense are created as CSV files. Therefore, these data can be easily processed into a report in a predetermined format using general spreadsheet software. Therefore, for example, in the flowchart shown in FIG. 4, after the maintenance result data in the broad sense is stored in the maintenance data storage unit 22, the maintenance result data in the broad sense is appropriately processed by spreadsheet software and printed as a report. Or a processing step for converting the file into a PDF file.

  As described above, according to the present embodiment, the information terminal device 40 can appropriately read out a necessary maintenance manual from the information management device 20 and use it for maintenance, so that the maintenance efficiency can be improved. The information transmitted and received between the information management device 20 and the information terminal device 40 is processed and converted so as to be data that can be displayed on a single page screen by a web browser. Therefore, the maintenance worker 91 can browse all the maintenance related information with only the web browser activated without switching the software according to the data format of the information. 40 convenience and operability can be improved.

  Furthermore, in the present embodiment, as is apparent from the flowchart shown in FIG. 4, the maintenance manual and the maintenance result data in a broad sense are stored in the information management device 20, and the data hardly remains in the information terminal device 40. It has become. Therefore, even if the information terminal device 40 is stolen, the outflow of information can be prevented.

  In the present embodiment, the information management device 20 does not make an inquiry to the information terminal device 40, and is always configured to call the information management device 20 from the information terminal device 40. Therefore, the information terminal device 40 Can be configured not to wait for wireless communication, the information terminal device 40 can suppress power consumption due to communication and can extend the continuous use time.
