Description of drawings

For a better understanding of the above and other objects, features, advantages and functions of the present invention, reference may be made to the preferred embodiments shown in the accompanying drawings. The same reference numbers in the figures refer to the same parts. It will be appreciated by those skilled in the art that the accompanying drawings are intended to schematically illustrate the preferred embodiments of the present invention and not to limit the scope of the invention in any way, and the various components in the drawings are not drawn to scale.

FIG. 1 is a schematic diagram of the operation logic of an alarm system according to a preferred embodiment of the present invention.

Detailed ways

Referring now to the accompanying drawings, specific embodiments of the present invention will be described in detail. What is described here is only the preferred embodiments of the present invention, and those skilled in the art can think of other ways to implement the present invention on the basis of the preferred embodiments, and the other ways also fall within the scope of the present invention.

The present invention provides an alarm system and an operation method suitable for an aircraft. FIG. 1 shows a logical schematic diagram of a method of operation according to a preferred embodiment of the present invention.

In a preferred embodiment, the alerting system includes an alerting unit, a display and an electronic checklist system. Wherein, the alarm unit is used to receive a fault or failure signal from the aircraft equipment, and send out alarm information, and the display can display the alarm information. The electronic checklist is configured to receive an alarm message from the alarm unit and generate a corresponding electronic checklist for an operator to perform an inspection operation.

The warning unit is configured to generate a predetermined type of warning message according to the content of the warning message, and the title of the electronic checklist generated by the electronic checklist system can display a color corresponding to the type of the received warning message. This setting allows the operator to not need to spend extra time and energy to check for faults, which can reduce the complexity of the operation and improve the operation efficiency.

Moreover, the alarm system is configured to change the title of the electronic checklist to a different indication mode when the equipment is restored to normal and the corresponding electronic checklist has been opened by the operator. Specifically, the title of the electronic checklist may present a white box and keep blinking, the blinking frequency is preferably 1 Hz, and the duty cycle is 0.5 seconds.

Preferably, when the device returns to normal and the corresponding electronic checklist has been opened by the operator, the electronic checklist pops up an override option for the operator to override. For example, the cursor of the electronic checklist can automatically jump to an override option at this time, and the override option can be, for example, a button marked as "override checklist". Providing an override option allows the operator to effectively intervene in the event of system failure or error reporting, improving operational accuracy.

Also preferably, the above-mentioned predetermined types of warning messages include warning messages, warning messages and advisory messages.

Corresponding to the warning message, the warning message and the advisory message, the electronic checklist is constructed such that: when the warning message is received, the title of the electronic checklist is displayed in red; when the warning disappears when the warning message is received. The title of the electronic checklist is displayed in amber; when the consultation message is received, the title of the electronic checklist is displayed in cyan. The contrasting colors of various colors can give the operator enough visual cues.

In this embodiment, the title of the electronic checklist can present a white box and keep blinking. That is to say, when the fault corresponding to the warning message is removed and the electronic checklist is opened, the title of the electronic checklist changes from red to a white frame and keeps flashing; when the fault corresponding to the warning message is removed and the electronic checklist is opened , the title of the electronic checklist changes from amber to a white box and keeps flashing; when the fault corresponding to the consultation message is removed and the electronic checklist is opened, the title of the electronic checklist changes from cyan to a white box and continues flashing.

More preferably, the electronic checklist is configured to display a graphic prompt corresponding to the type of the received alarm information in addition to the color prompt.

Referring to FIG. 1 , the operation method based on the above-mentioned alarm system will be described below.

In the method described in this embodiment, the warning message system collects the fault or failure signal of the aircraft equipment of the civil aircraft and sends out the warning message, wherein the type of the warning message is associated with the level of the abnormal warning condition; the electronic checklist system receives the The alarm message generates a corresponding electronic checklist for the operator to perform inspection operations, and the title of the electronic checklist can display a color corresponding to the type of the received alarm message.

For example, when the warning message is received, the title of the electronic checklist is displayed in red; when the alert disappears is received, the title of the electronic checklist is displayed in amber; when the consultation message is received The title of the electronic checklist is displayed in cyan.

Once the fault is eliminated and the equipment returns to normal, referring to FIG. 1 , at this time, the alarm system receives a message that the equipment has returned to normal and displays it on the display device. At the same time, the electronic checklist system also receives corresponding signals. After that, the control module will make a judgment to determine whether the electronic checklist corresponding to the previous fault is in an open state. If the judgment result is no, the process of the fault is completed; The title changes to a different indication than before, and an override option pops up for the operator to override.

Regarding the color conversion, the example given in this embodiment is: when the fault corresponding to the warning message is removed and the electronic checklist is opened, the title of the electronic checklist changes from red to a white frame and keeps flashing; when the warning message When the corresponding fault is cleared and the electronic checklist is opened, the title of the electronic checklist changes from amber to a white box and keeps flashing; when the fault corresponding to the consultation message is cleared and the electronic checklist is opened, the electronic checklist 's title changes from cyan to a white frame and blinks continuously.

After the operator sees the white box on the title of the electronic checklist and keeps flashing, he can know that the fault has been eliminated, and he does not need to spend extra time and energy to check the fault, which can improve the efficiency and bring convenience to the operator.

According to the present invention, the electronic checklist in the alarm system can receive and feed back various types of alarm messages to the operator. When the abnormal checklist corresponding to the alarm message triggered by the fault is opened, if the fault disappears at this time, the electronic The checklist will feed back this situation to the operator, and the operator no longer needs to check and judge by himself.

The foregoing description of various embodiments of the present invention is provided for the purpose of description to one of ordinary skill in the relevant art. It is not intended that the invention be exclusive or limited to a single disclosed embodiment. As mentioned above, various alternatives and modifications of the present invention will be apparent to those of ordinary skill in the art of the above teachings. Thus, while some alternative embodiments have been described in detail, other embodiments will be apparent to or relatively readily developed by those of ordinary skill in the art.
