DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The aforementioned illustrations and following detailed descriptions are exemplary for the purpose of further explaining the scope of the present disclosure. Other objectives and advantages related to the present disclosure will be illustrated in the subsequent descriptions and appended drawings.

[0017] Referring to FIG. 1, the present disclosure provides a monitoring system 1 for an aircraft guiding process, and for monitoring a docking process of an aircraft F guided by a guiding information display 80 of a VDGS (Visual Docking Guidance System) along a J-line J at an apron. The monitoring system for an aircraft guiding process of the present disclosure may be applied at a single apron of a small-size airport, or at multiple aprons of a large-size airport. The VDGS, in addition to the guiding information display 80, also includes a laser scanning device and a computer, in which the laser scanning device is for emitting laser beams used for detection and distant measurement. Relevant details thereof may be referred to in U.S. Pat. No. 9,177,483 B2, “Guiding method for aircraft docking process,” and U.S. Pat. No. 9,459,119 B2, “Aircraft guidance system having reviewing and video synchronization abilities, and reviewing and video synchronization device of the same” under the same applicant.

[0018] Taking one single apron as an example, the monitoring system 1 for an aircraft guiding process includes an image capturing module 10, an image integrating unit 23, a monitoring display 22 and a video recorder 24. Each image capturing module 10 includes a first camera 11 for filming the docking process of the aircraft F to obtain a docking video V1, and a second camera 12 for filming the screen of the guiding information display 80 to obtain a guiding information video V2. The image integrating unit 23 integrates the docking video V1 and the guiding information video V2 into an integrated video V0 in a synchronously-displayed and adjoining manner. The video recorder 24 records the integrated video V0.

[0019] In the present embodiment, the first camera 11 may be built in the guiding information display 80, or be at a position close to the guiding information display 80. The second camera 12 may be installed at the front of the guiding information display 80, e.g., it may be fixed on the outer frame of the guiding information display 80 by a frame 121, or may be installed at a terminal T of an airport.

[0020] In the present embodiment, the image integrating unit 23, the monitoring display 22 and the video recorder 24 may be integrated in a monitoring computer 20. The monitoring computer 20 may include the monitoring display 22 and a mainframe 21. To be more specific, the image integrating unit 23 may be achieved by loading relevant software into the mainframe 21, and the software may be, but not limited to, installed in a hard disk or a chip. The video recorder 24 may be, but not limited to, a hard disk or a portable memory device. However, the present disclosure is not limited to the above instances; for example, the video recorder may be other devices capable of recording and be separate from the monitoring computer, such as a portable recorder.

[0021] After the VDGS detects the aircraft F, the VDGS gives a triggering signal to start guidance, and the first and second cameras 11, 12 are triggered to start recording. The video recorder 24 is activated to record the integrated video V0 after the monitoring computer 20 receives the triggering signal.

[0022] After the VDGS completes guiding the aircraft F, the VDGS transmits an ending signal for finishing the guidance to the monitoring computer 20, and after the monitoring computer 20 receives the ending signal, the video recorder 24 ends the recording of the integrated video V0.

[0023] Reference is made to FIG. 2, which illustrates the docking process of the aircraft F filmed by the image capturing module 10, and each screen of the guiding information display 80. To the left side of FIG. 2, a top view of the aircraft F sliding from the runway to the apron is shown. The first camera 11 of the image capturing module 10 is used to film the docking process of the aircraft F from the front (different from the top view of FIG. 2) to provide the aforementioned docking video V1. To the right side of FIG. 2, a guiding screen of the guiding information display 80 in different situations is shown. In situation C1, the aircraft F gradually draws near the J-line J and, in situations C2 to C6, the aircraft F moves along the J-line J until arriving at the stop line S. The second camera 12 of the image capturing module 10 is used in the present disclosure to film the aforementioned guiding screens of the guiding information display 80 to provide the guiding information video V2.

[0024] Before the aircraft F reaches the J-line, the ground crew may determine and enter the aircraft model into the system, such as A320, and it would be displayed on a model column 81 of the guiding information display 80. Alternatively, the appearance features of the aircraft F may be obtained by a laser scanner 83 of the VDGS, a computer may determine whether the entered model is correct and transmit a relevant message for the ground crew's reference, so that the correct model can be transmitted to the model column 81 of the guiding information display 80.

[0025] Reference is made with FIG. 2. Under situation C1, the laser scanner 83 starts to scan the aircraft F and then the VDGS is activated. After being confirmed by the ground crew, the scanning result is then transmitted to the model column 81 of the guiding information display 80 to display the model of the aircraft F for the pilot's reference. If the displayed model of the aircraft F is incorrect, the aircraft F should stop and confirm with the ground crew or other control members until an appropriate docking procedure for the correct model is secured to avoid mis-docking accidents.

[0026] In situation C2, the guiding information display 80 further shows that the aircraft F is biased to the left. The single dotted line 841 in a left bottom display area 84 represents the J-line J, the double dotted line 842 represents the location of the aircraft F relative to the J-line J, and the dotted arrow 843 represents the indication to move on, so as to indicate to the pilot that the aircraft F is biased to the left so that he is able to direct the aircraft F to the right and keep moving on.

[0027] In situation C3, the guiding information display 80 further shows in a middle display area 82 that the distance between the aircraft F and the stop line S is 30 meters, which means that the aircraft F has entered into the guiding area. Only a double dotted line is shown in the left bottom display area 84, representing that the aircraft F is already on the J-line J. The dotted arrow 843 represents the indication to move on. The pilot continues piloting the aircraft to move forward.

[0028] In situation C4, the guiding information display 80 further shows in the middle display area 82 that the distance between the aircraft F and the stop line S is 20 meters, and in the left bottom display area 84, the double dotted line 842 is at the right side of the single dotted line 841, which reminds the pilot that the aircraft F is biased to the right and should be directed to the left. The dotted arrow 843 represents the instruction to move on. The pilot continues piloting the aircraft to move forward.

[0029] In situation C5, the guiding information display 80 shows in the middle display area 82 that the distance between the aircraft F and the stop line S is 8.2 meters. In the left bottom display area 84, only the double dotted line 842 is shown, which means that the route of the aircraft F is modified to be back on the J-line J. In the left bottom display area 84, a dotted horizontal line 845 is shown on top of the dotted arrow 843, which represents the stop line S. The pilot slows down the speed of the aircraft F when nearing the stop line S to slowly approach the stop line S.

[0030] In situation C6, a “STOP” word is displayed in the middle display area 82 of the guiding information display 80, indicating that the aircraft F has arrived at the stop line S and that the pilot should stop the aircraft F immediately, and the left bottom display area 84 shows a T shape, which represents “stop piloting.”

[0031] Reference is made to FIG. 3, where FIG. 3 shows a diagram of an integrated video. In the present embodiment, by a preferable manner of stacking, the docking video V1 and the guiding information video V2 are synchronously shown, which allows them to form an adjoining integrated video V0. The integrated video V0 preferably shows the number of the gate VG as well, such as “B5 Gate.” The first camera 11 and the second camera 12 at the apron can simultaneously and collectively display, record and playback by utilizing software, allowing users to synchronously be aware of the contents of the in-time video of the aircraft and that displayed on the guiding information display 80.

[0032] For the recording process of the present disclosure, the video recorder 24 may use the VDGS to provide a trigger function. When the aircraft enters into the guiding process, the first camera 11 and the second camera 12 are triggered to record, and the video recorder 24 is activated to store the integrated video V0. Moreover, as in situation C6 shown in FIG. 2, after the VDGS completes guidance of the aircraft F, an ending signal would be transmitted to the monitoring computer 20, and the video recorder 24 ends the storing of the integrated video V0 after the monitoring computer 20 receives the ending signal.

[0033] The monitoring computer 20 of the present disclosure preferably takes each docking of an aircraft F as one event, and accordingly stores the integrated videos V0 as video files. The file name of the video files should preferably include the recording time and the number of the apron, e.g., 20150101_0502_B5.mpg. The guidance videos can easily be retrieved based on the recording time and number of apron in the file names, thus facilitating the inspection of potential mis-guidances. Moreover, the videos can be synchronously played in pilot training. Furthermore, the video files may be used to showcase the VDGS via the Internet.

[0034] Reference is made to FIG. 4. The monitoring system for an aircraft guiding process of the present disclosure may be applied to multiple aprons of an airport. The monitoring system 1a for an aircraft guiding process may include multiple image capturing modules 10, and an image switching device 30. The multiple image capturing modules 10 correspond to multiple aircrafts F1, F2, F3 and multiple guiding information displays 80. The multiple image capturing modules 10 connect with the image switching device 30, and the image switching device 30 electrically connects with the image integration unit 23, so as to form multiple integrated videos V0.

[0035] For the image capturing module 10a on the left side of FIG. 4, by filming the docking process of the aircraft F1 to obtain a docking video V1 by the first camera 11, the docking video V1 is transmitted to the mainframe 21 of the monitoring computer 20 by the channel CH01 and by the switching device 30. The screen of the guiding information display 80a is filmed by the second camera 12 and a guiding information video V2 is then obtained, and the guiding information video V2 is transmitted to the mainframe 21 of the monitoring computer 20 by the channel CH02 and by the switching device 30.

[0036] For the image capturing module 10b in the middle of FIG. 4, a docking video V1 is filmed by the first camera 11, and the docking video V1 is transmitted to the mainframe 20 of the monitoring computer 20 by the channel CH07 and by the switching device 30. The screen of the guiding information display 80b is filmed by the second camera 12 and a guiding information video V2 is then obtained, and the guiding information video V2 is transmitted to the mainframe 21 of the monitoring computer 20 by the channel CH08 and by the switching device 30.

[0037] For the image capturing module 10c at the right side of FIG. 4, a docking video V1 is filmed by the first camera 11, and the docking video V1 is transmitted to the mainframe 20 of the monitoring computer 20 by the channel CH23 and by the switching device 30. The screen of the guiding information display 80c is filmed by the second camera 12 and a guiding information video V2 is then obtained, and the guiding information video V2 is transmitted to the mainframe 21 of the monitoring computer 20 by the channel CH24 and by the switching device 30.

[0038] As shown in FIG. 5, information regarding the corresponding gate number of each of the aforementioned channels may be saved in the monitoring computer 20. The two videos transmitted from each predetermined pair of adjoining channels, e.g., channels CH01 and CH02, channels CH07 and CH08, and channels CH23 and CH24, can respectively be integrated into integrated videos V0, V0′, and V0″ by software. The above-mentioned three integrated videos V0, V0′ and V0″ are displayed on the same monitoring screen 22 in parallel, but the number of parallel displays should not be limited to that disclosed in the present embodiment. For example, more integrated videos could be displayed in parallel if the width of the monitoring screen 22 is wider.

[0039] The guiding information video V2 at the bottom of the integrated video V0″ in FIG. 4 appears to be blank, which means that the ending signal has been received and the recording has stopped. If the monitoring computer 20 receives a new triggering signal, which means the VDGS has detected that another aircraft F is about to dock, the monitoring computer 20 may remove the completed integrated video from the monitoring screen 22, such as the integrated video V0″, and transmit an integrated video corresponding to the new triggering signal to the monitoring screen 22.

[0040] According to the monitoring system for aircraft guiding process of the present disclosure, the monitoring system further provides a control interface 220 electrically connected with the guiding information display for the monitoring staff to give an indication signal, such as a “STOP” word for emergency stops to be displayed on the guiding information display to guide the aircraft. The control interface 220 may be designed to have multiple buttons, such as a stop button, etc.

[0041] As shown in FIG. 6, according to the monitoring system for an aircraft guiding process of the present disclosure, a diagram showing all aprons of an airport can be provided through the monitoring screen 22. The diagram may be switched by the control interface 220, so as to be displayed on the monitoring screen 22. Multiple aprons are at each side of Terminals T1 and T2, and are each represented by an alphabet and a digit, a square box representing that no aircraft is docked thereon, an aircraft shape represents that an aircraft is docked thereon, and an aircraft shape with a circle represents that the aircrafts F1, F4 and F5 are under docking process.

[0042] According to the monitoring system for an aircraft guiding process, a monitoring method for an aircraft guiding process and for monitoring a docking process of an aircraft guided by a guiding information display of a VDGS (Visual Docking Guidance System) along a J-line at an apron is also provided. The monitoring system includes the following steps (with FIG. 1 referred together): Step S11, filming a docking video V1 of the aircraft F during a docking process; Step S12, filming a guiding information video V2 of the guiding information display 80 during a guiding process; Step S13, integrating the docking video V1 and the guiding information video V2 into an integrated video V0 in a synchronously-displayed and adjoining manner; Step S14, transmitting the integrated video V0 to a monitoring display; and Step S15, recording the integrated video V0.

[0043] Moreover, the monitoring method for aircraft guiding process of the present disclosure further includes a step of transmitting a triggering signal for starting a guidance after the VDGS detects an aircraft F, in order to start a storing of the integrated video V0; and transmitting an ending signal for finishing the guidance after the VDGS completes guiding the aircraft F, in order to end the storing of the integrated video V0.

[0044] The step of recording the integrated video further includes: Step S151, based on recognizing each docking of an aircraft F as a single event, storing the integrated video V0 as a video file; and Step S152, storing the recording time and number of the apron in the file name of the integrated video V0.

[0045] Referring back to FIG. 4, the monitoring system 1a for aircraft guiding process includes multiple image capturing modules 10, and the present disclosure further includes the following steps: providing an image switching device 30 configured to receive the multiple docking videos V1 and the multiple guiding information videos V2; electrically connecting the image switching device 30 with the image integrating unit 23 to form the multiple integrated videos V0, V0′, V0″; removing the integrated video in which guidance has been completed according to a new triggering signal; and transmitting the integrated video corresponding to the new triggering signal to the monitoring display.

[0046] Furthermore, the present disclosure includes the following step: providing a control interface 220 electrically connected with the guiding information display, so that the monitoring staff can give an indication signal to be displayed on the guiding information display to guide the aircraft.

[0047] In sum, the features and functions of the monitoring system for an aircraft guiding process according to the present disclosure in management of the VDGS at each apron of an airport are that, by utilizing the specific arrangement of the image capturing module 10, and by the integration of the image integrating unit 23, functions such as convenient management, in-time monitoring, remote maintenance and recording retrieval and in-field display may be accomplished.

[0048] The present disclosure may be used in a control room for in-time monitoring of the status of each apron, and can even give an instant instruction therefrom such that manpower can be saved. For example, by giving a stopping instruction from a control room, the safety of in-field guidance may be enhanced. By connecting the monitoring computer 20 to the Internet, the guiding status of each apron may be checked at any time via the Internet, including aircraft piloting behavior and the functional status of the system.

[0049] According to the present disclosure, manpower in management and maintenance can be saved, and by connecting to the Internet, the effects of the VDGS can be instantly exhibited in detail.

[0050] The descriptions illustrated supra set forth simply the preferred embodiments of the present disclosure; however, the characteristics of the present disclosure are by no means restricted thereto. All changes, alterations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the present disclosure delineated by the following claims.
