Description

Technical Field

[0001] This invention relates to a method for assisting flight crew in handling malfunctions, applicable to aircraft avionics systems, and enabling integrated design for the identification and handling of warning and alert levels. This invention also relates to a system for assisting flight crew in handling malfunctions, which can be integrated as part of the aircraft avionics system. This invention belongs to the field of aircraft systems. Background Technology

[0002] According to relevant civil aviation regulations, flight crew alarms are divided into three levels: warning, alert, and alert. The first two levels of alarms require the crew to identify and respond immediately and include corresponding handling procedures (i.e., a set of operating steps).

[0003] The existing mainstream solutions for providing alarm indication can be divided into Solution 1 and Solution 2. Based on the analysis and research of publicly available information, a brief description is as follows.

[0004] Option 1 adopts a 4+1 display unit layout. In the normal configuration, the three display units inside the main instrument panel and at the front of the central control panel use a display allocation design based on a multi-function window (MFW). Crew members can control different display units separately through the format switches of the left / right display selection panel (DSP) and the left / right multi-function keypad (MFK), and can manually switch to view the summary page (SYS) or the electronic checklist (CHKL) as needed. The electronic checklist is used to display the aforementioned procedures.

[0005] However, in Option 1, the Crew Alarm Messages (CAS) of the aircraft avionics system, along with the summary pages and electronic checklists, are relatively independent subsystems and lack an integrated design. Upon receiving an alarm, the crew needs to manually issue a request command. In particular, when faced with multiple alarms, the crew needs to spend time and effort issuing commands to retrieve summary pages and / or abnormal handling procedures, indicating insufficient support provided by the aircraft avionics system.

[0006] Option 2 uses two fixed windows to integrate the display of alarms, diagrams, and handling procedures. This system is called Electronic Centralized Aircraft Monitoring (ECAM). The Warning Display (WD) window provides alarm messages and corresponding streamlined abnormal handling procedures, while the System Display (SD) window automatically updates to provide real-time system status indications.

[0007] However, the window positions of the warning display window and the system display window in Scheme 2 are fixed, and a display allocation design based on a multi-functional window is not adopted.

[0008] As aircraft avionics systems integrate more and more functions, there is a growing demand to provide more functionality in several windows with optimal visibility. Therefore, the need for a multi-functional window display allocation design is becoming increasingly urgent.

[0009] Therefore, there is an urgent need to propose a system with a certain degree of automation that integrates the identification and handling of alarms at the alert level and above, in order to assist the unit in handling faults. Summary of the Invention

[0010] To address the aforementioned problems in the prior art, the inventors provide a highly automated method for assisting flight crews in handling faults. This method is used in aircraft avionics systems and can achieve integrated design of fault alarms, system status diagrams, and handling procedures.

[0011] In a first example of a method for assisting a generator unit in handling a fault, the method includes the following steps:

[0012] After the system updates in real time and receives alarm information, the alarms are sorted from highest to lowest level, and the highest-level alarm is obtained. The system then determines whether the highest-level alarm is a notification, warning, or alert. If the highest-level alarm is a notification, the method ends. If the highest-level alarm is a warning or alert, the system checks if it is associated with a diagram page. If associated, the diagram page for the highest-level alarm is displayed in the first window, and the method ends. If not associated, the corresponding handling procedure for the highest-level alarm is displayed in the first window, and the method ends.

[0013] In a second example of the method, the first example can be optionally included. The method further includes: when the highest-level alarm is associated with a diagram page, a soft switch is further used to focus the cursor on the handling procedure of the diagram page for the highest-level alarm in the first window. This allows crew members to easily access the handling procedure for the alarm when needed, reducing their workload and minimizing human error.

[0014] In a third example of the method, one or more of the first and second examples may be optionally included. The method further includes: when the current highest-level alarm is associated with a summary page, further determining whether the first window already displays the summary page of the current highest-level alarm; if the first window already displays the summary page of the current highest-level alarm, updating the summary page of the current highest-level alarm in the first window instead of popping it up; and if the first window does not display the summary page of the current highest-level alarm, popping it up in the first window. Therefore, the crew can obtain the latest summary page and understand the real-time status of the alarms.

[0015] In a fourth example of the method, one or more of the first to third examples may be optionally included. The method further includes: when the highest-level alarm is associated with a diagram page, a soft switch is added to focus the cursor on the handling procedure of the diagram page for the highest-level alarm in the first window. This allows crew members to easily access the handling procedure for the alarm when needed, reducing their workload and minimizing human error.

[0016] In the fifth example of the method, one or more of the first to fourth examples may be optionally included. The method further includes: when the current highest level alarm is not associated with the diagram page, further determining whether the first window has already displayed the handling procedure corresponding to the current highest level alarm, and when the first window has already displayed the handling procedure corresponding to the current highest level alarm, no operation is performed instead of popping up the handling procedure corresponding to the current highest level alarm, and when the first window has not displayed the handling procedure corresponding to the current highest level alarm, the handling procedure corresponding to the current highest level alarm is popped up in the first window.

[0017] This invention also discloses a system for assisting flight crew in handling faults, which can be used as part of an aircraft avionics system. The system includes an alarm sorting module, an alarm matching module, and a display management module. It can execute one or more of the following: The alarm sorting module, after receiving alarm information in real time, sorts the alarms from highest to lowest level based on the received alarm levels and obtains the current highest-level alarm; the alarm matching module determines whether the current highest-level alarm is a notification, warning, or alert; and if the current highest-level alarm is a notification, no action is taken; or if the current highest-level alarm is a warning or alert, further action is taken. The system performs a step-by-step operation, determining whether the current highest-level alarm is associated with the simplified diagram page. Based on the association result, it sends a request command to the display management module, which displays the simplified diagram page for the current highest-level alarm. Alternatively, if the highest-level alarm is not associated with the simplified diagram page, the system sends a request command to the display management module, which displays the corresponding handling procedure for the current highest-level alarm. The display management module automatically designates the first window among multiple windows on the aircraft and receives request commands from the alarm matching module. It then displays either the simplified diagram page for the current highest-level alarm or the corresponding handling procedure for the current highest-level alarm in the first window.

[0018] This invention relates to aircraft avionics systems and provides a method and system with highly automated features to assist flight crews in handling faults. This method and system enable integrated design of fault alarms, system status, and handling procedures, which helps improve aircraft safety, enhance crew situational awareness, and reduce crew workload.

[0051] First, this invention primarily relates to aircraft avionics systems in any field of aircraft. In particular, this invention relates to the fault-handling portion of aircraft avionics systems, such as the integrated design of alarm identification and handling, but not limited to providing a simplified diagram of system status and abnormal handling procedures.

[0052] The terms “including,” “having,” “comprising,” and variations thereof, as used herein, are intended as open-ended transitional phrases, terms, or words that require the presence of a specified component / step, but also allow for the presence of other components / steps.

[0053] In this invention, unless explicitly stated otherwise, the terms “first,” “second,” etc., are not intended to indicate any difference in order, position, quantity, or importance, but are merely used as labels to distinguish different positions or components, to differentiate one element, component, region, and / or location from another element, component, region, and / or location.

[0054] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0055] Figure 1 A block diagram of a method 1 for assisting a unit in handling malfunctions according to an embodiment of the present invention is shown schematically.

[0056] In a non-limiting example, the method 1 of the present invention for assisting a unit in handling a fault includes, at step 13, obtaining the current highest level alarm, which can be achieved by receiving alarms and sorting alarms at preceding steps 11 and 12.

[0057] In a non-limiting example, after obtaining the current highest-level alarm, the method 1 of the present invention for assisting the crew in handling faults includes, at step 21, determining the type of the current highest-level alarm (hereinafter referred to as the alarm). As mentioned above, flight crew alarms for aircraft are divided into three levels: warning, alert, and alert. The first two levels of alarms require the crew to immediately identify and respond, and include corresponding handling procedures (i.e., handling actions, operating steps), while alert-level alarms do not require further action.

[0058] In this example, when the alarm type is a prompt at step 21, the method 1 of the present invention for assisting the unit in handling faults can proceed to the end.

[0059] Furthermore, if the alarm type is warning or alert at step 21, the method 1 for assisting the unit in handling faults of the present invention may include, at step 23, determining whether the alarm is associated with the schematic page.

[0060] Generally, alarms are divided into two categories: those related to abnormal operating environments and those related to abnormal system states. The latter are fault alarms, some of which are associated with system status diagrams of electromechanical systems such as gas, electricity, fuel, and hydraulic systems. Furthermore, for all fault alarms, it is recommended to provide the crew with abnormal handling procedures so that they can correctly respond to abnormal system states. That is, fault alarms include both those with diagrams and abnormal handling procedures, and those without diagrams but with abnormal handling procedures.

[0061] Therefore, for fault alarm messages at the warning and alert levels, corresponding simplified diagram pages and / or handling procedures can be automatically popped up and / or automatically updated according to the preset relationship.

[0062] In this example, when the alarm is associated with the diagram page at step 23, the method 1 for assisting the crew in handling faults according to the present invention may include, at step 25, popping up the diagram page of the alarm in a first window, wherein the first window 131 may be a window in a better viewing position among multiple windows of the aircraft automatically assigned by the system 100 for assisting the crew in handling faults, which employs a display allocation design based on a multi-function window. The method 1 for assisting the crew in handling faults according to the present invention may then proceed to its end.

[0063] In a non-limiting example, after step 25, the method 1 for assisting unit in handling faults according to the present invention may include, at step 28 (not shown), further focusing the cursor on the handling procedure of the current highest-level alarm's schematic page on the first window's schematic page. This allows the crew to easily access the handling procedure corresponding to the alarm when needed. This helps the crew to conveniently access the corresponding handling procedure after confirming the fault condition of the alarm on the schematic page, reducing the crew's workload and minimizing human error. The method 1 for assisting unit in handling faults according to the present invention can then proceed to the end.

[0064] Furthermore, if the alarm is not associated with the schematic page at step 23, the method 1 for assisting unit fault handling of the present invention may include, at step 27, displaying the handling procedure corresponding to the alarm in a first window. Subsequently, the method 1 for assisting unit fault handling of the present invention may proceed to the end.

[0065] Figure 2 Another block diagram of a method 1 for handling auxiliary unit malfunctions according to an embodiment of the present invention is shown schematically.

[0066] In this example, the method 1 for assisting unit in handling faults according to the present invention includes, at step 13, obtaining the current highest level alarm. For the sake of brevity, the same steps as those described above will not be explained again.

[0067] In this example, after obtaining the current highest level alarm, the method 1 of the present invention for assisting the unit in handling faults includes, at step 21, determining the type of the current highest level alarm (hereinafter referred to as the alarm).

[0068] In this example, when the alarm type is a prompt at step 21, the method 1 of the present invention for assisting the unit in handling faults can proceed to the end.

[0069] Furthermore, if the alarm type is warning or alert at step 21, the method 1 for assisting the unit in handling faults of the present invention may include, at step 23, determining whether the alarm is associated with the schematic page.

[0070] In this example, when the alarm is associated with the diagram page at step 23, the method 1 for assisting the crew in handling faults according to the present invention may include, at step 24, further determining whether the first window has already displayed the diagram page of the alarm, wherein the first window 131 may be a window in a better viewing position among the multiple windows of the aircraft automatically assigned by the system 100 for assisting the crew in handling faults, which adopts a display allocation design based on a multi-functional window.

[0071] When the simplified diagram of the alarm is already displayed in the first window at step 24, the method 1 for assisting unit fault handling of the present invention may include, at step 26, updating the simplified diagram of the alarm in the first window instead of popping up the simplified diagram of the alarm. The method 1 for assisting unit fault handling of the present invention can then proceed to the end.

[0072] Furthermore, if the simplified diagram of the alarm is not displayed in the first window at step 24, the method 1 for assisting unit fault handling of the present invention may include, as described above, displaying the simplified diagram of the alarm in the first window at step 25. The method 1 for assisting unit fault handling of the present invention may then proceed to its end.

[0073] In this example, after steps 25 and 26, the method 1 for assisting unit in handling faults according to the present invention may include, at step 28, further focusing the cursor on the handling procedure of the current highest-level alarm's schematic page in the first window. This allows the crew to easily access the corresponding handling procedure when needed. This helps the crew to conveniently access the handling procedure after confirming the fault condition corresponding to the alarm on the schematic page, reducing the workload of the crew and minimizing human error. The method 1 for assisting unit in handling faults according to the present invention can then proceed to the end.

[0074] Furthermore, when the alarm is not associated with the schematic page at step 23, the method 1 for assisting the unit in handling faults of the present invention may include, at step 29, determining whether the first window has already displayed the handling procedure corresponding to the alarm.

[0075] When the handling procedure corresponding to the alarm has been displayed in the first window at step 29, the method 1 for assisting the unit in handling faults of the present invention can proceed to the end.

[0076] Furthermore, if the handling procedure corresponding to the alarm is not displayed in the first window at step 29, the method 1 for assisting unit fault handling of the present invention may include, as described above, displaying the handling procedure corresponding to the alarm in the first window at step 27. The method 1 for assisting unit fault handling of the present invention may then proceed to completion.

[0077] Figure 3 A schematic diagram of a system 100 for assisting a unit in handling malfunctions according to an embodiment of the present invention is shown.

[0078] In a non-limiting example, the system 100 of the present invention for assisting unit in handling faults includes an alarm sorting module 110. The alarm sorting module 110 can sort received alarms to obtain the current highest-level alarm 111. The alarm sorting module 110 can be an existing alarm sorting module.

[0079] In one non-limiting example, the system 100 of the present invention for assisting unit in handling faults includes an alarm matching module 120 and a display management module 130. The alarm matching module 120 and the display management module 130 can realize an integrated design for alarm identification and handling.

[0080] In this example, the alarm matching module 120 is used to establish a matching relationship between fault alarms, system status diagram pages, and abnormal handling procedures. The alarm matching module 120 can determine whether the type 122 of the current highest-level alarm 111 (hereinafter referred to as the alarm) is a warning, alert, or prompt.

[0081] The alarm matching module 120 may take no further action based on the judgment result that the type of the current highest level alarm 111 (hereinafter referred to as the alarm) is prompt 121a.

[0082] In addition, the alarm matching module 120 can further operate based on the judgment result that the alarm type is warning or alert 121b, to determine whether the alarm is associated with the simplified page.

[0083] The alarm matching module 120 can send a demand command to the display management module 130 based on the judgment result of the alarm and the association 123a with the simplified page, and the command will pop up the simplified page of the alarm.

[0084] In addition, the alarm matching module 120 can send a demand command to the display management module 130 based on the judgment result that the alarm is not associated with the simplified page 123b, and the command will pop up the corresponding handling procedure for the alarm.

[0085] In this example, the display management module 130 is a display management module of the system 100 used to assist the crew in handling faults, employing a display allocation design based on a multi-functional window. The display management module 130 can automatically designate a window among multiple windows on the aircraft as the first window 131, where the first window 131 can be a window located in a better viewing position.

[0086] The display management module 130 can receive a request instruction from the alarm matching module 120 to pop up a simplified diagram page of the alarm, and pop up the simplified diagram page of the alarm in the first window 131.

[0087] Preferably, based on the judgment result of the association between the alarm and the summary page, the display management module 130 can further focus the cursor on the soft switch of the handling procedure of the summary page of the alarm in the first window 131.

[0088] In addition, the display management module 130 can receive a request instruction from the alarm matching module 120 to pop up the corresponding handling procedure for the alarm, and pop up the corresponding handling procedure for the alarm in the first window 131.

[0089] In a non-limiting example, based on the determination result of the association between the alarm and the summary page, the display management module 130 can further determine whether the first window 131 has already displayed the summary page of the alarm.

[0090] The display management module 130 can update the alarm's simplified page in the first window 131 based on the judgment result that the simplified page of the alarm has already been displayed in the first window 131, instead of popping up the simplified page of the alarm.

[0091] In addition, the display management module 130 can pop up the alarm's simplified page in the first window 131 based on the judgment result that the simplified page of the alarm is not displayed in the first window 131.

[0092] Preferably, based on the judgment result of the association between the alarm and the summary page, the display management module 130 can further focus the cursor on the soft switch of the handling procedure of the summary page of the alarm in the first window 131.

[0093] In a non-limiting example, based on the judgment that the alarm is not associated with the diagram page, the display management module 130 can further determine whether the first window 131 has already displayed the handling procedure corresponding to the alarm.

[0094] The display management module 130 can, based on the judgment result of the handling procedure corresponding to the alarm already displayed in the first window 131, perform no operation, instead of popping up the handling procedure corresponding to the alarm.

[0095] Based on the judgment result that the first window 131 does not display the corresponding handling procedure for the alarm, the display management module 130 can pop up the corresponding handling procedure for the alarm in the first window 131.
