Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for analyzing data related to a transport device such as an aircraft, and in particular, an analysis apparatus for integrating and analyzing aircraft flight data, failure data (failure data), and external image / audio data. About.
[0002]
[Prior art]
In general, in transportation equipment such as airplanes, the operation status data and / or failure data are recorded as record data, and the operation status and failure status of the transport equipment are analyzed based on the record data. .
[0003]
For example, an aircraft is equipped with a so-called flight data recorder (CSFDR), and flight status data (aircraft altitude, speed, direction, engine data, etc.) as flight status data is stored in the flight data recorder. ) Is recorded. Furthermore, the aircraft is provided with a failure status recording device (Data Transfer Equipment: DTE) that records failures (failure status) of various devices provided in the aircraft as failure data. In addition, the aircraft has an audio image recording device (Airband Video Tape Recorder / Cockpit Television Sensor: AVTR) that records the out-of-flight scenery viewed from the pilot's viewpoint during operation (in flight) as audio image data together with the voice of the pilot or the like. / CTVS) may be installed, and the flight image recording apparatus may also record various flight information along with the outside scenery. And the above-mentioned voice image data is used as a part of operation data.
[0004]
Depending on the aircraft, two flight recorders may be installed. One flight recorder is used, for example, when investigating the cause of an accident (this flight recorder is called CSMU), and the other flight recorder is used as an operation history. (This flight recorder is called SAU). These flight recorders record flight information and obtain flight status data at predetermined time intervals for each flight information (e.g., aircraft altitude, speed, direction, engine data) (for convenience of explanation below, flight information). The recorder shall record flight status data at the first time interval).
[0005]
On the other hand, the DTE is provided with a cassette (DTC) and a recorder unit (DTU), and records a failure state given from various aircraft devices at a predetermined second time interval. In addition, the audio image recording apparatus includes a camera and a recorder, and the recorder records the outside scene captured by the camera as image data and also records the voice of the pilot or the like as audio data.
[0006]
The flight status data, failure data, and sound image data recorded as described above are analyzed as necessary after the flight of the aircraft. Then, the flight status of the aircraft in flight is confirmed based on the flight status data (particularly, the flight status when a malfunction occurs), and the content of the malfunction is confirmed based on the failure data. Furthermore, the out-of-flight situation at the time of trouble occurrence is confirmed based on the voice image data and the trouble of the communication system during flight is confirmed.
[0007]
[Problems to be solved by the invention]
By the way, when analyzing the above-described flight status data, failure data, and sound image data, different analysis devices are used. That is, when analyzing flight status data, an analysis device (CSFDR analysis device) for a flight recorder is used, and similarly, when analyzing failure data, a DTC analysis device is used. Furthermore, an AVTR analysis device is used when analyzing audio image data. In other words, it is necessary to analyze the above three data separately because the analysis method differs depending on the data.
[0008]
However, in order to accurately analyze and confirm the flight state of the aircraft, it is necessary to associate three pieces of data. However, since each of the flight recorder, DTE, and audio / video recording apparatus is analyzed separately as described above because of different recording conditions and recording time intervals, it is possible to collate each data. There is a problem that it is difficult.
[0009]
In particular, when a problem occurs in an aircraft during flight, in order to investigate the cause, it is necessary to analyze the above three data in association with each other. As a result, there is also a problem that it takes time to investigate the cause.
[0010]
Furthermore, the results analyzed as described above are accumulated in a database for each data. When using a database, it is necessary to collate three data, and the database cannot be used effectively. There is a problem. In particular, it is not possible to record a countermeasure against a defect by associating three pieces of data. For this reason, when a similar defect occurs, there is a problem that the countermeasure cannot be quickly performed.
[0011]
An object of the present invention is to provide a data analysis apparatus that can analyze operation conditions data, failure data, and outside scenery data in association with each other.
[0012]
Another object of the present invention is to provide a data analysis apparatus capable of easily investigating the cause when a problem occurs.
[0013]
Still another object of the present invention is to provide a data analysis apparatus capable of quickly dealing with a problem.
[0014]
[Means for Solving the Problems]

Status information is included, and the fault data includes a plurality of fault information, and the operation status after interpolation is performed by interpolating the operation status data and the fault data with the sampling interval being a predetermined sampling interval. Conversion means for converting data and post-interpolation fault data; and control means for displaying and controlling the post-interpolation operation status data and the post-interpolation fault data in a time-synchronized manner based on a predetermined reference time. It is possible to obtain a transport equipment data analysis apparatus characterized by having
[0015]
As described above, in the present invention, after the operation status data and failure data sampling intervals having different sampling intervals are substantially unified to a predetermined interval, the operation status data and failure data are synchronized with respect to time on the display. Since the screen is divided and displayed, operation status data and failure data can be comprehensively related and analyzed.
[0016]
Furthermore, image data obtained by photographing a scenery outside the transport device is provided, and the control means displays the image data as an image on the display in synchronization with the post-interpolation operation status data starting from the reference time. Accordingly, image data (for example, an outside scenery image) can be displayed in synchronization with the operation status data and the failure data, and the operation status data, the failure data, and the image data can be comprehensively associated and analyzed.
[0017]
The control means divides the display screen into at least first to third divided screens, and the post-interpolation operation status data, the post-interpolation failure data, and the image are divided into the first to third divided screens, respectively. In addition, the operation status data includes a plurality of items, and the control means determines the post-interpolation operation status data displayed on the first divided screen according to the selection of the item. To change. When the button for adding, correcting, or deleting the failure data is clicked, the control means permits addition, correction, or deletion of the failure data.
[0018]
When a failure event is selected from the failure data, the control means displays related data (for example, flight status data, image data). Since this data is synchronized with the failure data in time, the failure event can be easily analyzed.
[0019]
For example, the transportation device is an aircraft, the operation status data is flight status data indicating the flight status of the aircraft, and the predetermined reference time is a take-off time. Moreover, the shortest sampling interval is used as a reference | standard as the said predetermined sampling interval among the sampling intervals of the said operation status data and the said failure data. The operation status data, the failure data, and the image data may be collected via a wireless line.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments. In the following description, an aircraft is used as an example of transportation equipment, but other transportation equipment such as ships, high-speed trains, automobiles, etc., need to grasp the operation status and failure status. The present invention can also be applied to transportation equipment. In addition, dimensions, shapes, materials, relative arrangements, and the like in the following description are not intended to limit the scope of the present invention, but are merely illustrative examples, unless otherwise specified.
[0021]
First, referring to FIG. 1, the illustrated analysis apparatus includes a data processing device 10, which includes, for example, first to third data reading devices 11 to 13, a storage device 14, and the like. An input device (keyboard and mouse) 15 and a display device (display) 16 are connected. The above-described flight status data, failure data, and sound image data are input from the first to third data readers 11 to 13, respectively.
[0022]
Specifically, the first data reader 11 reads flight status data (CSFDR data) from the flight recorder (CSFDR) 21 and gives the flight status data to the data processing device 10 (flight status data is a plurality of flight information). (E.g., data on aircraft altitude, speed, heading, and engine). The aforementioned DTC 22 is inserted into the second data reader 12, and the second data reader 12 reads the failure data (DTC data) from the DTC 22, and provides the failure data to the data processor 10 (the failure data is the aircraft data). It has failure information about each device). The third data reading device 13 reads the audio image data (AVTR data) from the AVTR 23 and gives the audio image data to the data processing device 10. The data processing device 10 temporarily stores the audio image data in the storage device 14. To do.
[0023]
As described above, the flight recorder 21 collects and records flight status data at a predetermined first time interval, while the DTE collects failure data at a predetermined second time interval. And recorded in the DTC 22 (generally, the first time interval> the second time interval). The flight status data includes, for example, the aircraft altitude, speed, heading, engine status (engine data), and the like, but the data collection time interval may differ for each of these data. That is, the sampling interval differs for each type of data.
[0024]
The data processing device 10 includes a data conversion unit 10a. The data conversion unit 10a resamples each data with reference to data having the shortest sampling interval among flight status data and failure data. That is, each data is interpolated on the basis of the sampling interval of the data with the shortest sampling interval.
[0025]
For example, if there is data sampled (collected) at sampling periods (intervals) of 2 Hz, 4 Hz, 8 Hz, and 12 Hz (this data is referred to as first to fourth data), sampling of the first data The second to fourth data are sampled again with the period of 2 Hz as a reference to perform data conversion. In other words, in the aircraft, when the first data is sampled twice, the second data is only sampled once. Therefore, in the data conversion unit 10a, the same state as when the second data is sampled twice. (In other words, the second data is set so that the same data continues twice). Similarly, the third and fourth data are set so that the same data continues three times and four times, respectively.
[0026]
In this way, the data conversion unit 10a sets the flight status data and the failure data to the same sampling number with respect to the time axis (hereinafter, the data interpolated in this way is referred to as the interpolation flight status data and the interpolation failure data). The interpolated flight status data and the interpolated fault data are temporarily stored in the storage device 14.
[0027]
Referring also to FIG. 2, the data processing device 10 includes a data integration processing unit 10 b. The data integration processing unit 10 b transmits the above-described interpolation flight status data, interpolation failure data, and audio image from the storage device 14. Data is read and displayed on the display 16. At this time, as shown in FIG. 2, the data integration processing unit 10b integrates the interpolated flight status data, the interpolated failure data, and the image data in the audio image data and displays them on the display 16 as an integrated screen. In the illustrated example, the integrated screen is divided into four (hereinafter referred to as the first to fourth divided screens 161 to 164), and the first to third divided screens 161 to 163 have interpolation flight status data, Interpolation failure data and image data in audio image data are displayed. Note that a comment field for inputting a comment is displayed on the fourth divided screen 164 as described later. In the present embodiment, the first divided screen 161 is also called a CSFDR screen, the second divided screen 162 is also called a DTC screen, and the third divided screen 163 is also called an AVTR screen.
[0028]
On the first divided screen 161, the interpolated flight status data is displayed in a graph with the horizontal axis as the time axis. On the second divided screen 162, the failure data is displayed for each device / event (subsystem). The number of occurrences and the time are displayed.
[0029]
Now, in order to synchronize the flight status data and the failure data (DTC data) with respect to time, a reference event is selected in the aircraft. For example, when take-off (TAKEOFF) is selected as a reference (in this case, for example, the cursor is clicked according to “TAKEOFF” on the second divided screen 162), the data integration processing unit 10b uses the storage device 14 is detected and DTC data “TAKEOFF” is detected, and “TAKEOFF” of flight status data (CSFDR data) is detected. ("TAKEOFF" is detected based on load state data (W-O-W signal)).
[0030]
In this way, DTC data and CSFDR data are synchronized with “TAKEOFF” as the reference time (reference time). At this time, the data integration processing unit 10 b displays a “DTC-CSFDR synchronization screen” on the display 16.
[0031]
On this synchronization screen, a “TAKEOFF” number is displayed as “DTC data No.”, the time is displayed, and the CSFDR time is further displayed. When this synchronization screen is confirmed and the “OK” button is clicked, the data integration processing unit 10b synchronizes the DTC data and the CSFDR data with TAKEOFF ”as the reference time (reference time) and displays the data on the display 16. .
[0032]
Next, referring to FIG. 3, as described above, DTC data and CSFDR data are synchronized and displayed on the display 16 using TAKEOFF "as a reference time (reference time), and then CSFDR data and image data (AVTR) are displayed. Data).
[0033]
When synchronization between CSFDR data and image data (AVTR data) is performed, a message (AVTR data synchronization command) indicating that synchronization between CSFDR data and image data (AVTR data) is to be performed is input from the input device 15. The integrated processing unit 10b displays a CSFDR-AVTR synchronization screen as shown in FIG. On the other hand, on the third divided screen 163, AVTR data is displayed as an image, and on the third divided screen 163, the time (display time) after the display of AVTR data is displayed as the system time. On the other hand, the time of the video itself (the time added to the video at the time of shooting) is displayed.
[0034]
The input device 15 is operated to display an image of “TAKEOFF” in the AVTR data on the third divided screen 163. When the third divided screen 163 is monitored, the screen is switched when “TAKEOFF”, that is, “TAKEOFF” is known when the screen is observed. Enter the system time when "TAKEOFF" is entered in the "System time" field of the "AVTR screen".
[0035]
As described above, since the “TAKEOFF” time in the CSFDR data has already been detected, the data integration processing unit 10b synchronizes the “TAKEOFF” time in the CSFDR data with the system time described above, and performs the third division. The video display time on the screen 163 is reset.
[0036]
In this way, the data integration processing unit 10b synchronizes the CSFDR data, the CTC data, and the AVTR data with respect to time. Then, when the CSFDR data, CTC data, and AVTR data are synchronized as described above, for example, the screen shown in FIG. 4 is displayed on the display 16.
[0037]
In the fourth divided screen 164, a comment (T / S result) column is displayed, and various comments regarding a failure event are input to the T / S result column. That is, the determination results determined from the first to third divided screens 161 to 163 are input as comments. Then, in the data integration processing unit 10b, the comment input as described above is stored in the storage device 14. Further, the data integration processing unit 10b stores the CSFDR data, CTC data, and AVTR data synchronized as described above in the storage device 14 as integrated synchronization data. At this time, the comment described in the comment field is added to the integrated synchronization data.
[0038]
In the above description, various flight information is collectively described as flight status data, but actually, flight information is selected and displayed on the first divided screen 161. That is, the display item of CSFDR can be set / changed by operating the input device 15.
[0039]
When the display device setting / change is selected by operating the input device 15, the data integration processing unit 10b displays a display item change screen on the display as shown in FIG. The display item change screen is provided with a left column and a right column for selecting the left axis and the right axis of the first divided screen 161. In each column, the display item, display color, line thickness, Set the maximum and minimum values. When necessary items are entered in the left column and right column and the “OK” button is clicked, the data integration processing unit 10b searches for the corresponding data in the flight status data and displays it on the first divided screen 161. . At this time, the flight status data or the interpolated flight status data is selected according to the input from the display item change screen. That is, if you want to see the data before changing the sampling rate, you can select the flight status data, and if you want to see the data after changing the sampling rate, you can select the interpolated flight status data. .
[0040]
The synchronization after changing the display item is performed in the same manner as described above.
[0041]
Further, referring to FIG. 6, DTC data editing can be performed by operating input device 15. When the input device 15 is operated to select DTC data editing, the data integration processing unit 10b displays a DCT editing screen on the display as shown in FIG. The DCT edit screen includes a subsystem name input field, an occurrence frequency input field, a test number. An input field and a time field are provided, and necessary items are input to the DCT editing screen with reference to the DTC data displayed on the second divided screen 162. Click “Add” to move to the add screen. Similarly, if you click “Modify”, you will be redirected to the modification screen. Then, when “Delete” is clicked, the data related to the subsystem name is deleted.
[0042]
As mentioned above, when you click "Add", the add screen is displayed. Then, if there is an additional matter for the subsystem name, it is added. For example, in actual flight, so-called sukuk / pilot comments have many items that are regarded as malfunctions in the sense of pilots (alarm sounds, aircraft malfunctions, etc.). If there is such a problem, enter it on the add screen as an additional item. In the data integration processing unit 10b, when an additional item is input, the additional item is stored in the storage device 14 in association with the failure data. That is, it is added as an MFL (maintenance fault list) (in other words, it is databased as a defective item). If the database is formed in this way, it becomes easy to search for a failure event.
[0043]
On the other hand, when “Modify” is clicked, an add screen is displayed. If there is a correction item for the subsystem name, correction is performed. For example, the matters that are analyzed and confirmed from actual flight status data and failure data may differ from the pilot feeling described above. In such a case, the DTC data is corrected as necessary. That is, the DTC data can be corrected in consideration of the pilot feeling.
[0044]
As can be easily understood from the above description, in the illustrated example, the flight status data with different sampling intervals and the sampling interval of the fault data are substantially unified to a predetermined interval, and then the flight status data with respect to time. Since the failure data and the image data (out-of-flight scenery data) are synchronized and displayed on the display, the flight status data, the failure data, and the image data can be comprehensively correlated and analyzed.
[0045]
Further, when a failure event (subsystem name) is selected from the failure data, related data (for example, flight status data, image data) is called from the storage device, and this data is synchronized in time with the failure data. This makes it easier to analyze failure events.
[0046]
Furthermore, regarding CSFDR data, if the CSFDR display item is changed, all items can be displayed, and since the sampling rate is unified as described above, a plurality of items are displayed on the same screen. be able to.
[0047]
In addition, as for DTC data, it is possible to search for a failure event or the like for the subsystem just by inputting the MFL test number, and it is also possible to add a pilot comment or the like.
[0048]
By the way, in the above description, it has been described that the flight status data, the failure data, and the voice image data are collected after the aircraft has landed. However, these data may be collected from the aircraft in real time via the wireless line. Good. For example, if these data are collected from an aircraft in real time using a satellite communication line and analyzed by the above-described data analysis device (that is, if data analysis is performed on the ground), the failure event is immediately detected. Can be dealt with.
[0049]
【The invention's effect】
As described above, in the present invention, after the operation data (flight status data) and failure data sampling intervals having different sampling intervals are substantially unified to a predetermined sampling interval, the operation data and failure data with respect to time are obtained. Since the screen is divided and displayed on the display in synchronization with the image data (outside scenery data), the operation data, the failure data, and the image data can be comprehensively related and analyzed.
[0050]
Furthermore, when a failure event is selected from the failure data, related data (for example, operation data, image data) is recalled from the storage device, and this data is synchronized in time with the failure data. There is also an effect that it becomes easy.
[0051]
As for operation data, all items can be displayed by changing the display items of operation data, and since the sampling rate is unified as described above, multiple items are displayed on the same screen. There is an effect that can be done.
