Description

Technical Field

[0001] The present application relates to the field of aviation technology, and in particular to a combined warning system and a combined warning method for monitoring an aircraft flight environment. Background Art

[0002] As we all know, the control devices in the cockpit of an aircraft are the main human-machine interface between the crew and the control system. They are not just physical input devices, but also need to establish effective communication with the crew through precise feedback. In modern aviation technology, the crew inputs target values ​​(such as speed, heading, attitude, etc.) and modes (such as autopilot, take-off and landing modes, etc.) by manipulating various control devices (such as joysticks, knobs, buttons, touch screens, etc.). These control devices are closely connected with the flight control system to achieve precise control of the aircraft. In order to ensure the intuitiveness and rapid response of the crew's operations, these control devices need to be closely integrated with the cockpit display system (such as the main display, HUD (head-up display), etc.) to form a closed-loop feedback system. For example, when the crew adjusts the heading or speed, the display system will promptly feedback the current status to ensure that the crew can make corresponding operational decisions.

[0003] Among the control devices in the cockpit of an aircraft, the warning system is a key component for flight safety. It is mainly used to alert the crew members when the aircraft has abnormal system status (such as engine failure, hydraulic system abnormality, etc.) or abnormal flight status (such as too low altitude, unstable airflow, etc.). The transmission method of warning information needs to be hierarchical according to the severity, and different warning levels (such as warning, emergency, failure, etc.) should be designed in combination with the reaction time and decision-making ability of the crew. However, due to the limited main field of view of the aircraft cockpit, the crew needs to pay attention to flight data, control panel, external field of view and warning information at the same time during the driving process. Therefore, the design of the cockpit must not only ensure that the crew can control the aircraft efficiently, but also accurately locate the fault area and ensure that the warning information can quickly attract the attention of the crew at the most urgent moment. This is a key problem.

[0004] In addition, traditional warning systems often rely on regional prompts (such as warning signs and area indicator lights on the display screen). Due to the compact cockpit space and the limited number and size of displays, it is inconvenient to install too many warning modules in the main field of view. As a result, when the cockpit requires multiple warning status indications, and the warning needs to attract the crew's attention and accurately locate the warning area, the limited main field of view cannot meet the needs. If a large number of warning modules are installed in the main field of view, the cockpit information with limited space will be crowded and chaotic, which will cause the crew to be unable to pay attention to and accurately locate the information in time. Summary of the invention

[0005] Technical problem to be solved by the invention

[0006] The present application is formed to solve the above-mentioned technical problems, and its purpose is to provide a combined alarm system and a combined alarm method, which can effectively present relatively specific alarm information in a limited space, so as to quickly attract the crew's attention and take appropriate countermeasures.

[0007] Technical solutions adopted to solve technical problems

[0014] Preferably, the primary viewing area warning module is located in front of the pilot, and the non-primary viewing area warning module is located to the side, rear or above the pilot.

[0015] Preferably, the main viewing area alarm module and the non-main viewing area alarm module display different alarm information simultaneously.

[0016] The present application also provides a combined alarm method, comprising: generating a detection signal through a detection unit; judging whether an alarm is required based on the detection signal through a control unit, and generating an alarm control signal when it is judged that an alarm is required; and performing alarm processing based on the alarm control signal through an execution unit.

[0017] The alarm control signal at least includes an auditory alarm signal, a main viewing area alarm signal and a non-main viewing area alarm signal; the execution unit at least includes an auditory alarm module, a main viewing area alarm module and a non-main viewing area alarm module.

While ensuring the readability, recognizability and priority of the information, it can also be sufficient to attract the crew's attention and respond quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 2 is a schematic diagram showing the structure of a combined alarm system.

[0025] Figure 2 is a flow chart illustrating a combined alarm method. DETAILED DESCRIPTION

[0026] The present application is further described below in conjunction with the following embodiments. It should be understood that the following embodiments are only used to illustrate the present application, but not to limit the present application. The same or corresponding reference numerals in the figures represent the same components, and repeated descriptions are omitted. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0027] In the description of the present application, it should be noted that the terms "first", "second", and "third" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance. The orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description and are not to be understood as limitations on the present application. The terms "installed", "connected", and "connected" should be understood in a broad sense, and those of ordinary skill in the art can understand the specific meanings of the above terms in the present application according to specific circumstances.

[0028] Hereinafter, a combined alarm system and a combined alarm method according to an embodiment of the present application will be described in detail with reference to the accompanying drawings. However, for the sake of clear description and understanding, some technical terms and / or technical terms involved in the present application will be described or defined before the detailed description.

[0029] The "primary visual area (primary field of view)" mentioned in this application refers to the visual area in front of the aircraft cockpit that is most commonly used and most easily accessible by the crew in normal flight conditions, that is, the area that the crew can see without turning their heads or deviating from the center line of sight when controlling the aircraft. This area is one of the cores of cockpit design. All key flight instruments, display systems, control devices and warning information need to be clearly presented in this visual area to ensure that the crew can obtain necessary flight information and make decisions in the shortest possible time.

[0030] The "non-primary viewing area" mentioned in this application refers to other areas of the crew's field of vision in the aircraft cockpit, excluding the primary viewing area in front. Although the non-primary viewing areas are not the main focus of the crew's vision, they still carry a large amount of flight information, warning content and auxiliary control systems. The crew may need to check these areas regularly or occasionally during flight, especially when performing complex tasks or responding to emergencies.

[0031] like Figure 1 As shown, the combined alarm system of this embodiment includes: a detection unit, a control unit and an execution unit. The execution unit includes an auditory alarm module, a main viewing area alarm module and a non-main viewing area alarm module.

[0032] In this embodiment, the detection unit detects whether there is an abnormality in the aircraft system. The detection unit uses various sensors (such as smoke detectors, temperature sensors, etc.) to detect the operating status of the aircraft (i.e., warning conditions) in real time and converts it into an electrical signal (i.e., detection signal) and sends it to the control unit. The detection unit may include at least one sensor, which may be, for example, one or more of an infrared sensor, an acoustic wave sensor, a temperature sensor, and a pressure sensor.

[0033] In this embodiment, the control unit receives the detection signal from the detection unit and determines whether an abnormal situation occurs (i.e., an alarm judgment). The control unit generates and outputs a corresponding alarm control signal based on the detection signal to drive the auditory alarm module, the main visual area alarm module, and the non-main visual area alarm module. Specifically, the control unit includes a processor and a memory. The processor is used to execute the alarm judgment logic, which usually includes operations such as data acquisition, calculation, comparison, and decision-making. For example, it can be an MCU (microcontroller unit), DSP (digital signal processor) or a more complex CPU. The memory is used to store pre-set rules, such as alarm thresholds, rule logic, historical data, etc.

[0034] When the control unit receives various detection signals (such as fire alarm, smoke, system failure, etc.) from the detection unit, it determines whether an alarm is required according to the preset logic. If it is determined that an alarm is required, a corresponding alarm control signal is generated according to the type and severity of the detection signal, and sent to the execution unit to drive the auditory alarm module, the main visual area alarm module and the non-main visual area alarm module respectively. Specifically, the control unit is pre-set with the following rules: the normal temperature range of the engine is 0℃~80℃. When the engine temperature is detected to be less than 0℃ or the engine temperature is ≥80℃, it is determined that the engine is abnormal (that is, an alarm is required), and an alarm control signal is generated and sent. Further, it can also be set as follows: when the engine temperature is less than 0℃, it is a low temperature abnormality, and an alarm control signal with a low alarm level is generated; when the engine temperature is ≥80℃, it is a high temperature abnormality, and an alarm control signal with a medium alarm level is generated; when the engine temperature is ≥100℃, it is an ultra-high temperature abnormality, and an alarm control signal with a high alarm level is generated.

[0035] In this embodiment, the auditory alarm module reminds the crew members to pay attention to abnormal situations occurring during the flight by means of sound. In order to ensure that the crew can respond in the shortest time under complex flight conditions, the audio alarm generally generates sounds of different frequencies, rhythms, and loudness to prompt the crew members with specific alarm information. Specifically, the auditory alarm module receives an alarm control signal (an auditory alarm signal in this embodiment) from a control unit, and makes corresponding notifications of abnormal conditions according to the auditory alarm signal. In this embodiment, the auditory alarm module can be a buzzer or a speaker, wherein the buzzer has the advantages of being small, low power consumption, and low cost, and can produce simple buzzing sounds, while the speaker can provide more complex sound outputs, such as voice prompts or multi-frequency buzzing sounds.

[0036] In this embodiment, the main visual area warning module is located in the pilot's main visual field, and conveys important warning information to the crew in a visual manner, ensuring that the crew can promptly detect and respond to potential dangers or faults during flight. In this embodiment, the main visual area warning module is located in the direct line of sight of the crew, that is, in front. Specifically, the alarm program is pre-set in the main visual area warning module, and the main visual area warning module receives the alarm control signal from the control unit (in this embodiment, the main visual area alarm signal), and prompts the corresponding abnormal state according to the main visual area alarm signal. In addition, due to the limited main visual field area, the warning prompts of the main visual area warning module are usually relatively simple and concentrated, for example, it can be a warning light, annunciator or a small micro display. In this embodiment, when the main viewing area alarm module is a warning light, the trigger state, alarm level, color and character of the alarm light lighting function are pre-set in the module. For example, it can be divided into red (high risk), amber (caution), blue (non-emergency), and green (safe) according to the alarm level. When the main viewing area alarm module is a small micro display, numbers can be displayed according to the alarm level. For example, the number 1 represents a level 1 alarm (such as a fire alarm, etc.), the number 2 represents a level 2 alarm (such as a flight control failure, etc.), the number 3 represents a level 3 alarm (such as overspeed, etc.), and so on.

[0037] In addition, in order to avoid excessive interference caused by multiple alarms, the main visual area alarm module can also be provided with a suppression unit. In this embodiment, the suppression unit can be a button or a switch, and the crew can confirm the alarm by pressing the button or switch and remove it from the visual feedback to avoid the alarm light from continuously lighting up and causing visual interference. In addition, a push switch with a light can also be used as both a warning light and a suppression unit, thereby further simplifying the structure.

[0038] In this embodiment, the non-primary visual area warning module is located in an area outside the pilot's primary visual field, and also conveys important warning information to the crew in a visual manner, ensuring that the crew can promptly detect and respond to potential dangers or faults during flight. Specifically, in this embodiment, the non-primary visual area warning module is located outside the direct line of sight of the crew, such as to the side, rear or top, and these positions are relatively spacious and sufficient to configure relatively large equipment. The non-primary visual area warning module receives an alarm control signal from the control unit (a non-primary visual area alarm signal in this embodiment), and provides specific prompts for the corresponding abnormal state according to the non-primary visual area alarm signal. Specifically, the non-primary visual area warning module is preferably an indicator light with a specific content logo or a display screen or indicator board that provides specific alarm information, so that the crew can be informed of the specific situation of the abnormality.

[0039] Similarly, the non-primary viewing area warning module may also be provided with a suppression unit. In this embodiment, the suppression unit may be a release button or switch, and the crew may suppress a certain warning or release the warning by pressing the button or switch.

[0040] In addition, the non-primary visual area warning module may include not only visual warning methods, but also tactile warning methods, such as applying vibration feedback technology to provide tactile feedback on the control stick or seat, to further ensure that the crew members are sufficiently aware of the warning. In addition, the non-primary visual area warning module is not limited to the vicinity of the pilot or in the cockpit, but can also be set in multiple places on the aircraft, so as to ensure that the warning information can sufficiently attract the attention of the crew members.

[0041] It can be seen that in the combined warning system of the present embodiment, the auditory warning module, the main visual area warning module and the non-main visual area warning module are combined. The auditory warning and the main visual area warning are used to attract the attention of the crew first, and then the specific warning information of the non-main visual area guides the crew to accurately locate the abnormal situation. The crew takes the best response measures according to the cockpit instructions to ensure the safety of the entire flight mission. In other words, in the present embodiment, the auditory warning module and the main visual area warning module can not only attract the attention of the crew, but also effectively guide the crew to automatically and spontaneously pay attention to the detailed information displayed on the non-main visual area warning module. Such a split display can not only share the space configuration pressure of the main visual area well, but also prompt more information in the non-main visual area with relatively abundant space, for example, in addition to accurate positioning, it can also display intelligent response strategies and response rankings.

[0042] In addition, the combined warning system of the present embodiment can realize the complete warning function through the above-mentioned functionally independent modules or units, so it is possible to conveniently establish data transmission between the modules and units by hard-wired connection. For example, the units or modules can be connected through bus protocols (such as CAN bus) and the like. In addition, the combined warning system (specifically the control unit) and other systems or modules can also use bus protocols (such as CAN bus) to realize data transmission between modules. In other words, the combined warning system according to the present embodiment forms a simple structure and functionally independent structure through modular design and hard-wired design, which can be quickly installed and put into use on various types of aircraft.

[0043] The following, combined Figure 2 The combined alarm method based on the above-mentioned combined alarm system is described.

[0044] First, each sensor continuously detects aircraft flight information and environmental changes. The detection unit generates a detection signal based on the sensor's detection and sends it to the control unit.

[0045] The control unit receives the detection signal from the detection unit, determines whether an alarm is required, that is, determines whether an abnormality occurs. When it is determined that an alarm is not required (i.e., no abnormality occurs), no operation is performed. When it is determined that an alarm is required (i.e., an abnormality occurs), a corresponding alarm control signal is generated according to the input signal. The alarm control signal includes at least an auditory alarm signal, a main viewing area alarm signal, and a non-main viewing area alarm signal, thereby driving the auditory alarm module, the main viewing area alarm module, and the non-main viewing area alarm module. It should be clear that different events detected by the sensor generate different signals, so that the signals received by the control unit are different, and the alarm control signals generated by the control unit based on different signals are also different.

[0046] In addition, when multiple alarm control signals are triggered at the same time, the control unit can also determine and generate a priority, automatically suppressing lower priority alarms based on the priority, and ensuring that the most urgent alarm control signals are transmitted first.

[0047] Specifically, after receiving the detection signal from the detection unit, the control unit determines whether the number of alarms required, that is, the number of abnormalities occurring, is greater than one. In other words, whether the same or different faults or abnormalities occur at multiple locations on the aircraft at the same time. When the control unit determines that the number of alarms required, that is, the number of abnormalities occurring, is not greater than one (that is, only one abnormality occurs), an alarm control signal (that is, an auditory alarm signal, a main viewing area alarm signal, and a non-main viewing area alarm signal) is generated according to the input detection signal, and sent to the auditory alarm module, the main viewing area alarm module, and the non-main viewing area alarm module, respectively. When the control unit determines that the number of alarms required, that is, the number of abnormalities occurring is greater than one (for example, abnormalities occur in multiple places and multiple abnormal detection signals are generated), an alarm control signal (that is, an auditory alarm signal, a main viewing area alarm signal, a non-main viewing area alarm signal) is generated according to each input detection signal, and a priority is set for each alarm control signal according to a pre-set rule. Then, each alarm control signal (that is, an auditory alarm signal, a main viewing area alarm signal, a non-main viewing area alarm signal) is sent together with its priority to the auditory alarm module, the main viewing area alarm module, and the non-main viewing area alarm module, respectively.

[0048] As a pre-set rule, for example, when multiple alarm signals are triggered at the same time, the control unit can divide the priority according to the degree of urgency, and each priority represents a different degree of urgency. The so-called degree of urgency is, for example, the occurrence of an abnormal situation that is most endangering flight safety. The following is only explained by specific examples. It should be understood that the examples are only used to promote understanding, not a limiting means. Specifically, the situation that threatens flight safety the most and requires the crew to respond immediately and take emergency measures quickly is set as the first-level alarm with the highest priority, such as: engine or cabin fire, wing fracture, major failure of the combustion system, cabin damage and depressurization, etc. The more serious situation that requires the crew to respond in a short time and may escalate if not handled in time is set as the second-level alarm, such as: engine performance degradation, hydraulic system failure, fuel leakage, automatic driving failure, etc. The situation that is less serious and requires the crew's attention but will not immediately affect flight safety is set as the third-level alarm, such as: overspeed alarm, cabin temperature is too high or too low, auxiliary power failure, insufficient air source pressure, etc. Situations that are of minor severity and require the crew's attention but usually do not affect flight safety are set as the lowest priority level 4 alarms, such as: small equipment failure, non-critical sensor or instrument failure, cabin lighting facility failure, etc. Therefore, when multiple alarm signals are triggered at the same time, the control unit generates corresponding auditory alarm signals, main visual area alarm signals, and non-main visual area alarm signals based on each signal, and determines the priority of each signal based on a pre-set rule (i.e., sets a priority for each signal), and then sends the auditory alarm signal, main visual area alarm signal, non-main visual area alarm signal and priority information corresponding to each signal to the auditory alarm module, main visual area alarm module, and non-main visual area alarm module, respectively.

[0049] The auditory warning module receives the auditory warning signal from the control unit and performs corresponding operations, such as ringing a buzzer, etc. The auditory warning module can warn without distinguishing signals, that is, a warning tone is used regardless of the signal, as long as the sound can be used to remind the crew of abnormality.

[0050] In addition, the auditory alarm module can also perform different sound operations for different auditory alarm signals according to pre-set rules to avoid the same sound representing multiple different alarms, thereby avoiding confusion among crew members and ensuring that the sound of each alarm type has its own uniqueness. For example, as a pre-set rule, it can be the urgency of the alarm. High-priority alarms will use loud, high-frequency, and continuous sounds, while low-priority alarms may be gentler, low-frequency, or of shorter duration. More specifically, high-frequency, continuous, and loud warning sounds can be generated for events with high urgency (i.e., priority) such as fire alarms and engine failures, and gentler, intermittent audio signals can be generated for events with low urgency (i.e., priority) such as excessive ambient temperature. It can also be that the warning sound generated for events with high urgency continues for a long time until the alarm is processed or manually released, and the warning sound generated for events with low urgency sounds intermittently, or is automatically released after a certain number of repetitions.

[0051] Furthermore, when multiple alarm signals are triggered simultaneously, the auditory alarm module ensures that the most urgent alarm is sounded first according to the auditory alarm signal and priority, so as to avoid low-priority alarms interfering with high-priority alarms.

[0052] The main viewing area warning module receives the main viewing area warning signal from the control unit and performs corresponding operations, such as lighting up the warning light, etc. The main viewing area warning module can warn without distinguishing signals, that is, no matter what the signal is, a lighting mode is adopted as long as the abnormality can be prompted to the crew by lighting up the light.

[0053] In addition, the main visual area alarm module can also perform different display operations for different main visual area alarm signals according to pre-set rules. Provide visual alarms to the crew through light color, flashing mode or characters on the display, and identify their importance through different colors (such as red, amber, blue, etc.). Specifically, as a pre-set rule, it can be to make the warning light have different colors and flashing modes. For example, when an event with a high degree of urgency (i.e., priority) such as a fire alarm or engine failure occurs, the warning light is lit in red and becomes a high-frequency flashing or always-on state to ensure that the crew can identify it in time. When an event with a lower degree of urgency (i.e., priority) such as engine performance degradation and hydraulic system abnormality occurs, the warning light is lit in amber and becomes an intermittent flashing or always-on state to remind the crew to pay attention but not to cause excessive interference. When an event with a low degree of urgency (i.e., priority) such as excessive ambient temperature occurs, the warning light is lit in blue and becomes a non-flashing and always-on state.

[0054] Furthermore, when multiple alarm signals are triggered simultaneously, the main viewing area alarm module ensures that the most urgent alarm is lit first according to the main viewing area alarm signal and priority, so as to avoid low-priority alarms interfering with high-priority alarms.

[0055] The non-primary viewing area alarm module receives the non-primary viewing area alarm signal from the control unit and performs corresponding operations, such as lighting up the indicator light. The non-primary viewing area alarm module performs different display operations for different non-primary viewing area alarm signals according to pre-set rules.

[0056] Specifically, as a pre-set rule, the warning light may have different colors and flashing modes to distinguish different alarms. For example, as an example of an indicator light, when a specific indicator light representing abnormal engine performance is on, it reminds the crew to pay attention to possible abnormalities in the engine. When a specific indicator light representing abnormal cabin pressure is on, it reminds the crew to pay attention to the cabin pressure, and so on. For another example, as an example of a display screen or indicator board, the specific text or icon of the alarm can be displayed on the display screen, such as "fire alarm", "hydraulic system failure", etc. As long as the display area is sufficient, the display content is not limited, and even the alarm type, the specific location of the fault or other related information can be displayed, etc., to help crew members understand the nature of the alarm more quickly and facilitate accurate response.

[0057] Furthermore, when multiple alarm signals are triggered simultaneously, if the display area can display all the information, the non-primary viewing area alarm module will highlight or display the high-priority alarm at the top according to the non-primary viewing area alarm signal and priority, and the low-priority alarm will be displayed at the bottom. If the display area is limited and cannot display all, the non-primary viewing area alarm module will ensure that the most urgent alarm is displayed first according to the non-primary viewing area alarm signal and priority, so as to avoid low-priority alarms interfering with high-priority alarms. Even in extreme cases, it can automatically enlarge and display the alarms that need to be handled urgently, and appropriately simplify or hide other alarm information.

[0058] The crew can then remove and / or eliminate each warning in turn as needed. If the crew has taken countermeasures, the combined warning system should update the status in a timely manner to avoid repeated warnings.

[0059] In addition, the combined warning system can not only remind the crew, but also provide decision support for the crew, for example, providing the best response process and suggestions to assist the crew to make decisions quickly. As a result, the combined warning system tends to achieve intelligence and self-adaptation.

[0060] In summary, the combined warning system and the combined warning method according to the present application have a simple structure and a small size, and will not occupy too much space resources within the limited space of the aircraft.

[0061] In addition, the modular design allows each warning module to function independently but work closely together. This high independence makes it highly scalable and maintainable, making it very convenient for installation or modification on aircraft. It can be easily embedded in the existing aircraft architecture without the need for large-scale rewiring or system reconstruction, and will not affect the functions of other systems, thereby significantly shortening the modification cycle.

[0062] In addition, the use of hard-wired connections to establish data transmission between modules, rather than complex network communication protocols, makes data transmission more stable and reliable. Since the system can achieve complete warning functions by simply adding a few small modules to the original architecture of the aircraft, it can occupy as few existing aircraft resources as possible, avoid the high costs and complex operations caused by the use of a large number of electronic equipment for transmission, and save modification costs and time. Moreover, the replacement and upgrade of the combined warning system can be completed quickly through hard wires, which greatly improves the adaptability and convenience of the system and facilitates the expansion and maintenance of aircraft functions.

[0063] In addition, the number and installation location of each module in the combined warning system can be flexibly configured according to the specific needs of the aircraft, maximizing the adaptability and scalability of the system and providing the crew with accurate, fast and convenient warnings.

The combined alarm method according to claim 8, characterized in that: A sound operation is performed based on the auditory alarm signal through the auditory alarm module, a lighting operation is performed based on the main viewing area alarm signal through the main viewing area alarm module, and a display operation is performed based on the non-main viewing area alarm signal through the non-main viewing area alarm module.

10. The combined alarm method according to claim 8, characterized in that: When it is determined based on the detection signal that an alarm needs to be issued, If it is determined that no alarm is necessary, no operation is performed; If it is determined that an alarm is required, the detection signal generates a corresponding alarm control signal.

11. The combined alarm method according to claim 10, characterized in that: When it is determined that an alarm is required, it is further determined whether the number of alarms required is greater than one. If greater than one, a priority is set for each alarm control signal, and an execution unit performs alarm processing based on the priority and the alarm control signal.

12. The combined alarm method according to claim 11, characterized in that: When it is determined that the number of alarms that need to be issued is greater than one, the control unit divides the priorities according to the urgency of the alarms.

13. The combined alarm method according to claim 12, characterized in that: When the execution unit performs alarm processing based on the priority and the alarm control signal, the alarm control signal with a high priority is processed preferentially.
