Description

A combined alarm system and a combined alarm method Technical Field

[0001] This application relates to the field of aviation technology, and in particular to a combined alarm system and method for monitoring the flight environment of an aircraft. Background Technology

[0002] As is well known, the control devices in an aircraft cockpit are the primary human-machine interface between the crew and the control system. They are not merely physical input devices; they also require precise feedback to establish effective communication with the crew. In modern aviation technology, crew members input target values ​​(such as speed, heading, and attitude) and modes (such as autopilot and takeoff / landing modes) by manipulating various control devices (such as joysticks, knobs, buttons, and touchscreens). These control devices are closely connected to the flight control system to achieve precise aircraft control. To ensure intuitive operation and rapid response from the crew, these control devices need to be tightly integrated with the cockpit display system (such as the main display and HUD, forming a closed-loop feedback system). For example, when the crew adjusts the heading or speed, the display system will promptly provide feedback on the current status, ensuring that the crew can make appropriate operational decisions.

[0003] Among the control devices in an aircraft cockpit, the warning system is a critical component for flight safety. It is primarily used to alert the crew when abnormal system states (such as engine failure, hydraulic system anomalies, etc.) or abnormal flight conditions (such as low altitude, unstable airflow, etc.) occur. The delivery of warning information needs to be tiered according to severity, taking into account the crew's reaction time and decision-making ability, with different warning levels (such as warning, emergency, malfunction, etc.) designed. However, due to the limited primary field of view in the aircraft cockpit, the crew needs to simultaneously monitor flight data, control panels, external visibility, and warning information during flight. Therefore, cockpit design must not only ensure that the crew can operate the aircraft efficiently but also accurately locate the fault area, ensuring that warning information quickly reaches the crew's attention in the most urgent moments—a critical challenge.

[0004] Furthermore, traditional alarm systems often rely on regional alerts (such as warning signs and area indicator lights on displays). Due to the compact cockpit space and the limited number and size of displays, it is inconvenient to install too many alarm modules in the main field of view. As a result, when the cockpit requires multiple alarm status indications, and the alarms need to attract the crew's attention and accurately locate the alarm area, the limited main field of view cannot meet the requirements. Installing a large number of alarm modules in the main field of view would make the limited cockpit space crowded and cluttered with information, thus preventing the crew from paying timely attention to and accurately locating information. Summary of the Invention

[0005] The technical problem that the invention aims to solve

[0006] This application was developed to solve the aforementioned technical problems. Its purpose is to provide a combined alarm system and method that can effectively present relatively specific alarm information in a limited space, so as to quickly attract the attention of the crew and enable them to take appropriate countermeasures.

[0007] Technical solutions adopted to solve technical problems

[0008] This application provides a combined alarm system, comprising: a detection unit for detecting alarm condition-related information; a control unit for receiving detection signals from the detection unit and determining whether an alarm needs to be triggered; and an execution unit for performing an alarm operation when an alarm is required.

[0009] The execution unit includes: an auditory alarm module, which is used to issue an auditory alarm signal when an alarm is required; a main view area alarm module, which is used to display alarm information in the main view area when an alarm is required; and a non-main view area alarm module, which is used to display alarm information in a non-main view area when an alarm is required.

[0010] Preferably, the detection unit includes a sensor, which is one or more of an infrared sensor, an acoustic sensor, a temperature sensor, and a pressure sensor.

[0011] Preferably, the control unit includes a processor and a memory, wherein the processor is used to execute alarm judgment logic and the memory is used to store pre-set rules.

[0012] Preferably, the auditory alarm module includes a buzzer or a speaker.

[0013] Preferably, the main view area alarm module is located in the pilot's main view area, and the non-main view area alarm module is located in an area outside the pilot's main view area.

[0014] Preferably, the main view alarm module is located in front of the pilot, and the non-main view alarm module is located to the side, behind, or above the pilot.

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

[0016] This application also provides a combined alarm method, comprising: generating a detection signal through a detection unit; determining whether an alarm needs to be triggered based on the detection signal through a control unit, and generating an alarm control signal when it is determined that an alarm needs to be triggered; and performing alarm processing based on the alarm control signal through an execution unit.

[0017] The alarm control signals include at least audible alarm signals, main view alarm signals, and non-main view alarm signals; the execution unit includes at least an audible alarm module, a main view alarm module, and a non-main view alarm module.

[0018] Preferably, the auditory alarm module performs a sound operation based on the auditory alarm signal, the main view area alarm module performs a lighting operation based on the main view area alarm signal, and the non-main view area alarm module performs a display operation based on the non-main view area alarm signal.

[0019] Preferably, when it is determined that an alarm needs to be triggered based on the detection signal, if it is determined that no alarm needs to be triggered, no operation is performed; if it is determined that an alarm needs to be triggered, the detection signal generates a corresponding alarm control signal.

[0020] Preferably, when it is determined that an alarm needs to be issued, it is further determined whether the number of alarms required is greater than one. If it is greater than one, a priority is set for each alarm control signal, and the execution unit performs alarm processing based on the priority and the alarm control signal.

[0021] Preferably, when it is determined that the number of alarms required is greater than one, the control unit divides the priorities according to the urgency of the alarms.

[0022] Preferably, when the execution unit performs alarm processing based on the priority and the alarm control signal, the alarm control signal with higher priority is processed first.

[0023] Therefore, it can effectively present alarm information in the limited display space of the aircraft cockpit by combining auditory and visual means, and can accurately present the alarm type and / or clearly identify the alarm source. While ensuring the readability, recognizability and priority of the information, it can also attract the attention of the crew and enable a rapid response. Attached Figure Description

[0026] The present application is further described below with reference to the following embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present application. The same or corresponding reference numerals in the figures denote the same components, and repeated descriptions are omitted. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0027] In the description of this application, it should be noted that the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience and simplification of the description of this application, and should not be construed as limiting this application. The terms "installation," "connection," and "joining" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] The combined alarm system and combined alarm method according to one embodiment of this application will be described in detail below with reference to the accompanying drawings. However, for the sake of clarity and understanding, some technical terms and / or technical expressions used in this application will be explained or defined before the detailed description.

[0029] The "primary field of view" mentioned in this application refers to the area in front of the crew member in the aircraft cockpit that is most frequently used and easily accessible during normal flight. In other words, it is the area that the crew member can see without turning their head or deviating from their line of sight when controlling the aircraft. This area is one of the core elements of cockpit design; all critical flight instruments, display systems, controls, and warning information need to be clearly presented within this field of view to ensure that the crew member can obtain necessary flight information and make decisions in the shortest possible time.

[0030] The term "non-primary line of sight" as used in this application refers to other areas within the crew's field of vision in the aircraft cockpit, excluding the primary line of sight directly ahead. While non-primary lines of sight are not the primary focus of the crew's line of sight, they still contain a significant amount of flight information, warnings, and auxiliary control systems. Crew members may need to periodically or occasionally review these areas during flight, especially when performing complex tasks or responding to emergencies.

[0031] As shown in Figure 1, 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 view area alarm module, and a non-main view area alarm module.

[0032] In this embodiment, the detection unit detects whether there are any abnormalities in the aircraft system. The detection unit uses various sensors (such as smoke detectors, temperature sensors, etc.) to monitor the aircraft's operating status (i.e., alarm conditions) in real time and converts them into electrical signals (i.e., detection signals), which are then sent to the control unit. The detection unit may include at least one sensor, such as one or more of infrared sensors, acoustic sensors, temperature sensors, and pressure sensors.

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

[0034] When the control unit receives various detection signals (such as fire alarms, smoke, system malfunctions, etc.) from the detection unit, it determines whether an alarm needs to be issued based on preset logic. If an alarm is deemed necessary, it generates a corresponding alarm control signal based on the type and severity of the detection signal and sends it to the execution unit, driving the audible alarm module, the main visual alarm module, and the non-main visual alarm module, respectively. Specifically, the control unit is pre-set with the following rules: the normal engine temperature range is 0℃~80℃. When an engine temperature <0℃ or ≥80℃ is detected, it is determined to be an engine abnormality (i.e., an alarm is required), and an alarm control signal is generated and sent. Further, it can be set as follows: when the engine temperature <0℃, it is a low-temperature abnormality, generating a low-level alarm control signal; when the engine temperature ≥80℃, it is a high-temperature abnormality, generating a medium-level alarm control signal; and when the engine temperature ≥100℃, it is an overheating abnormality, generating a high-level alarm control signal.

[0035] In this embodiment, the auditory alarm module alerts the crew to abnormal situations occurring during flight through sound. To ensure the crew can react in the shortest possible time in complex flight environments, audible alarms typically generate sounds of different frequencies, rhythms, and loudnesses to alert the crew to specific alarm information. Specifically, the auditory alarm module receives alarm control signals (here, auditory alarm signals) from the control unit and announces corresponding abnormal states based on the auditory alarm signals. In this embodiment, the auditory alarm module can be a buzzer or a speaker. Buzzers have advantages such as small size, low power consumption, and low cost, and can produce simple buzzing sounds, while speakers can provide more complex sound outputs, such as voice prompts or multi-frequency buzzing sounds.

[0036] In this embodiment, the main line-of-sight (DOS) alarm module is located in the pilot's primary field of vision, conveying important alarm information to the crew visually to ensure that the crew can promptly detect and respond to potential dangers or malfunctions during flight. Specifically, the DOS alarm module is located within the crew's direct line of sight, i.e., in front of them. The DOS alarm module has a pre-set alarm program. It receives alarm control signals from the control unit (in this embodiment, the DOS alarm signal) and provides corresponding abnormal status alerts based on the DOS alarm signal. Furthermore, due to the limited DOS area, the alarm alerts from the DOS alarm module are typically simple and focused, such as alarm lights, signals, or small displays. In this embodiment, when the main view alarm module is an alarm light, the trigger state, alarm level, color, and characters of the alarm light lighting function are preset in the module. For example, the alarm level can be divided into red (high risk), amber (caution), blue (non-emergency), and green (safe). When the main view alarm module is a miniature 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), the number 2 represents a level 2 alarm (such as a flight control malfunction), the number 3 represents a level 3 alarm (such as an overspeed alarm), and so on.

[0037] Furthermore, to avoid excessive interference caused by multiple alarms, the main view alarm module can also be equipped with a suppression unit. In this embodiment, the suppression unit can be a button or a switch. The unit can confirm the alarm by pressing the button or switch and remove it from the visual feedback, preventing the alarm light from continuously illuminating and causing visual interference. Alternatively, an illuminated push-button switch can be used as both the alarm light and the suppression unit, thereby further simplifying the structure.

[0038] In this embodiment, the non-view-of-sight (NVS) alarm module is located outside the pilot's primary field of vision. It also conveys important alarm information to the crew visually, ensuring the crew can promptly detect and respond to potential hazards or malfunctions during flight. Specifically, in this embodiment, the NVS alarm module is located outside the crew's direct line of sight, such as to the side, rear, or above. These locations offer sufficient space for relatively large equipment. The NVS alarm module receives alarm control signals (in this embodiment, NVS alarm signals) from the control unit and provides specific alerts for corresponding abnormal states based on the NVS alarm signals. Preferably, the NVS alarm module is an indicator light with specific content markings or a display screen or indicator panel providing specific alarm information, thereby informing the crew of the specific abnormal situation.

[0039] Similarly, the non-main view alarm module can also be equipped with a suppression unit. In this embodiment, the suppression unit can be a release button or a switch, which the crew can press to suppress or clear an alarm.

[0040] Furthermore, non-line-of-sight (NOS) warning modules can include not only visual warnings but also tactile warnings, such as vibration feedback technology, providing tactile feedback on the control stick or seat to further ensure sufficient attention from the crew. Additionally, NOS warning modules are not limited to the area near the pilot or in the cockpit; they can be installed in multiple locations on the aircraft to ensure that warning messages are sufficiently noticed by the crew.

[0041] Therefore, the combined alarm system in this embodiment integrates an auditory alarm module, a main visual area (NVA) alarm module, and a non-NVA alarm module. First, auditory and NVA alarms attract the crew's attention. Then, specific alarm information from the non-NVA module guides the crew to accurately locate the anomaly. Based on cockpit instructions, the crew takes the best response to ensure the safety of the entire flight mission. In other words, in this embodiment, while attracting the crew's attention, the auditory and NVA alarm modules also effectively guide them to automatically and spontaneously pay attention to the detailed information displayed on the non-NVA alarm module. This split display not only effectively alleviates the space allocation pressure in the NVA but also provides more information in the relatively spacious non-NVA area, such as displaying intelligent response strategies and response priorities in addition to precise location.

[0042] Furthermore, the combined alarm system of this embodiment can achieve complete alarm functions through the aforementioned functionally independent modules or units, thus facilitating data transmission between modules and units via hard-wired connections. For example, units or modules can be connected via bus protocols (such as CAN bus). Additionally, the combined alarm system (specifically, the control unit) can also use bus protocols (such as CAN bus) to achieve data transmission between modules. In other words, the combined alarm system according to this embodiment, through modular and hard-wired design, forms a simple and functionally independent structure, enabling rapid installation and deployment on various aircraft models.

[0043] The following describes the combined alarm method based on the above combined alarm system with reference to Figure 2.

[0044] First, each sensor continuously monitors the aircraft's flight information and environmental changes. The detection unit generates detection signals based on the sensor detections and sends them to the control unit.

[0045] The control unit receives detection signals from the detection unit and determines whether an alarm is needed, i.e., whether an anomaly has occurred. If no alarm is needed (i.e., no anomaly has occurred), no operation is performed. If an alarm is needed (i.e., an anomaly has occurred), a corresponding alarm control signal is generated based on the input signals. This alarm control signal includes at least an audible alarm signal, a main view area alarm signal, and a non-main view area alarm signal, thereby driving the audible alarm module, the main view area alarm module, and the non-main view area alarm module. It should be understood that different events detected by the sensors generate different signals, resulting in different signals received by the control unit, and consequently, different alarm control signals generated by the control unit based on these different signals.

[0046] In addition, when multiple alarm control signals are triggered simultaneously, the control unit can also determine and generate priorities, and automatically suppress lower priority alarms according to the priorities to ensure that the most urgent alarm control signals are delivered first.

[0047] Specifically, after receiving the detection signal from the detection unit, the control unit determines the number of alarms required, i.e., whether the number of anomalies is greater than one. In other words, whether the same or different faults or anomalies occur simultaneously in multiple locations on the aircraft. When the control unit determines that the number of alarms required, i.e., the number of anomalies, is no more than one (i.e., only one anomaly occurs), it generates alarm control signals (i.e., auditory alarm signals, main line-of-sight (LAN) alarm signals, and non-LAN alarm signals) based on the input detection signals, and sends them to the auditory alarm module, the LAN alarm module, and the non-LAN alarm module, respectively. When the control unit determines that the number of alarms required, i.e., the number of anomalies is greater than one (for example, multiple anomalies occur in multiple locations, generating multiple anomaly detection signals), it generates alarm control signals (i.e., audible alarm signals, main view area alarm signals, and non-main view area alarm signals) based on each input detection signal. It then sets a priority for each alarm control signal according to a pre-set rule and sends each alarm control signal (i.e., audible alarm signals, main view area alarm signals, and non-main view area alarm signals) along with its priority to the audible alarm module, the main view area alarm module, and the non-main view area alarm module, respectively.

[0048] As a pre-defined rule, when multiple alarm signals are triggered simultaneously, the control unit can prioritize them according to their urgency, with each priority representing a different level of urgency. An example of urgency is the occurrence of an abnormal situation that poses the greatest threat to flight safety. The following examples are provided for illustrative purposes only and should not be construed as limiting the scope of the alarm. Specifically, the highest priority Level 1 alarm is designated for situations that pose the most serious threat to flight safety and require immediate crew response and rapid emergency measures. Examples include: engine or cabin fire, wing breakage, major pyrotechnic system malfunction, cabin depressurization, etc. Level 2 alarms are designated for situations that are relatively serious and require crew response within a short time, and whose escalation may occur if not handled promptly. Examples include: engine performance degradation, hydraulic system malfunction, fuel leak, autopilot failure, etc. Level 3 alarms are designated for situations that are less severe, require crew attention, but do not immediately affect flight safety. Examples include: overspeed alarm, excessively high or low cabin temperature, auxiliary power supply failure, insufficient air pressure, etc. Minor incidents requiring crew attention but generally not affecting flight safety are classified as the lowest priority Level 4 alarms. Examples include minor equipment malfunctions, non-critical sensor or instrument malfunctions, and cabin lighting malfunctions. Therefore, when multiple alarm signals are triggered simultaneously, the control unit generates corresponding audible alarm signals, main visual area (NVA) alarm signals, and non-NVA alarm signals based on each signal. It then determines the priority of each signal based on pre-defined rules (i.e., assigns priorities to each signal) and sends the corresponding audible alarm signals, VVA alarm signals, and non-NVA alarm signals, along with the priority information, to the audible alarm module, VVA alarm module, and non-NVA alarm module, respectively.

[0049] The auditory alarm module receives auditory alarm signals from the control unit and performs corresponding operations, such as sounding a buzzer. The auditory alarm module can issue alarms without distinguishing between signals, that is, it uses the same alarm tone regardless of the signal, as long as it can alert the crew to an abnormality through sound.

[0050] Furthermore, the auditory alarm module can also execute different sound operations for different auditory alarm signals according to pre-set rules, avoiding the same sound representing multiple different alarms, thus preventing confusion among crew members and ensuring that each alarm type has its own unique sound. For example, a pre-set rule could be the urgency of the alarm; high-priority alarms would use a loud, high-frequency, continuous sound, while low-priority alarms might be gentler, lower-frequency, or shorter in duration. More specifically, it could generate a high-frequency, continuous, loud warning sound for high-urgency events (i.e., high priority) such as fire alarms and engine malfunctions, and generate a gentler, intermittent audio signal for low-urgency events (i.e., excessively high ambient temperature). Alternatively, warning sounds for high-urgency events could continue for a long time until the alarm is handled or manually cleared, while warning sounds for low-urgency events could sound intermittently or automatically clear after repeating a certain number of times.

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

[0052] The main view alarm module receives alarm signals from the control unit and performs corresponding operations, such as illuminating alarm lights. The main view alarm module can issue alarms indiscriminately, meaning it uses the same illumination mode regardless of the signal, as long as the lights alert the crew to an anomaly.

[0053] Furthermore, the main view alarm module can also perform different display operations for different main view alarm signals according to pre-set rules. It provides visual alarms to the unit through light color, flashing pattern, or characters on the display, using different colors (such as red, amber, blue, etc.) to indicate their importance. Specifically, as a pre-set rule, the alarm lights can have different colors and flashing patterns. For example, when high-priority events such as fire alarms or engine failures occur, the alarm lights illuminate red and flash frequently or remain constantly lit to ensure timely identification by the unit. When less urgent events such as engine performance degradation or hydraulic system malfunctions occur, the alarm lights illuminate amber and flash intermittently or remain constantly lit to alert the unit without causing excessive interference. When low-priority events such as excessively high ambient temperatures occur, the alarm lights illuminate blue and remain constantly lit without flashing.

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

[0055] The non-primary view area alarm module receives non-primary view area alarm signals from the control unit and performs corresponding operations, such as illuminating an indicator light. Based on pre-set rules, the non-primary view area alarm module performs different display operations for different non-primary view area alarm signals.

[0056] Specifically, pre-defined rules could include different colors and flashing patterns for warning lights to distinguish between different alarms. For example, as indicator lights, when a specific indicator light representing abnormal engine performance illuminates, it alerts the crew to a potential engine malfunction; when a specific indicator light representing abnormal cabin pressure illuminates, it alerts the crew to the cabin pressure, and so on. As another example, as displays or indicator panels, the screen can display the specific text or icon of the alarm, such as "Fire Alarm" or "Hydraulic System Failure." The content can be unlimited as long as there is sufficient display area; it can even display the alarm type, the specific location of the fault, or other relevant information to help the crew quickly understand the nature of the alarm and respond accurately.

[0057] Furthermore, when multiple alarm signals are triggered simultaneously, if the display area can show all the information, the non-primary view alarm module will highlight or display high-priority alarms at the top and low-priority alarms at the bottom, based on the non-primary view alarm signals and their priorities. If the display area is limited and cannot display all the information, the non-primary view alarm module will ensure that the most urgent alarms are displayed first, preventing low-priority alarms from interfering with high-priority alarms. In extreme cases, it can even automatically enlarge the display of alarms that urgently need to be addressed, and appropriately simplify or hide other alarm information.

[0058] The crew can then sequentially deactivate and / or clear each alarm as needed. If the crew has already taken appropriate measures, the combined alarm system should be updated promptly to avoid generating duplicate warnings.

[0059] Furthermore, the combined alarm system can do more than just alert the crew; it can also provide decision support, such as offering optimal response procedures and suggestions to help the crew make quick decisions. Thus, the combined alarm system tends to achieve intelligence and adaptability.

[0060] In summary, the combined alarm system and combined alarm method of this application have a simple structure and small size, and will not occupy too much space resources in the limited space of the aircraft.

[0061] Furthermore, the modular design allows each alarm module to function independently yet work closely together. This high degree of independence gives it strong scalability and maintainability, making it very easy to install or retrofit on aircraft. It can be easily embedded into the existing aircraft architecture without large-scale rewiring or system reconstruction, and does not affect the functionality of other systems, thus significantly shortening the retrofit cycle.

[0062] Furthermore, the use of hard-wired connections for data transmission between modules, rather than complex network communication protocols, ensures more stable and reliable data transmission. Since the system can achieve complete alarm functionality by adding only a few small modules to the aircraft's existing architecture, it minimizes the use of existing aircraft resources and avoids the high costs and complex operations associated with using numerous electronic devices for transmission, thus saving on retrofit costs and time. Moreover, the replacement and upgrade of the combined alarm system can be quickly completed via hard-wired connections, greatly improving the system's adaptability and convenience, and facilitating aircraft functional expansion and maintenance.

[0063] Furthermore, the number and installation location of each module in the combined alarm system can be flexibly configured according to the specific needs of the aircraft, maximizing the system's adaptability and scalability, and providing the crew with accurate, fast, and convenient alarms.
