Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to an aircraft cabin pressure monitoring method, apparatus, device, and computer-readable storage medium. Background Art

[0002] As the aircraft ascends, the aircraft's pressurization system gradually increases the pressure, preventing passengers from experiencing discomfort due to the low pressure and lack of oxygen at high altitude. If the cabin loses pressure at high altitude, the oxygen leaks out and the pressure drops, causing passengers to swell instantly, suffocate from lack of oxygen, and gradually lose consciousness. Without sufficient oxygen, the ultimate result is death from hypoxia. Therefore, monitoring cabin pressure is crucial.

[0003] Due to the design and layout of some aircraft, such as the Boeing 757, Boeing 767, and Boeing 737CL, the cabin pressure monitoring system is located in the crew's blind spot (overhead). Decompression alarms are only issued when the cabin altitude reaches 10,000 feet, which gives the crew a short response time. This creates significant pressure on aviation safety, and this pressurization data cannot be read by the backend, significantly impacting the aircraft's background monitoring and analysis.

[0086] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to make and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art will recognize that the invention can be practiced without these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0087] The embodiments of the present application provide an aircraft cabin pressure monitoring method, apparatus, device, and computer-readable storage medium, which are described in detail below.

[0088] The aircraft cabin pressure monitoring method in an embodiment of the present invention is applied to an aircraft cabin pressure monitoring device, which is arranged in an aircraft cabin pressure monitoring equipment. The aircraft cabin pressure monitoring equipment is provided with one or more processors, memories, and one or more applications, wherein the one or more applications are stored in the memories and configured to be executed by the processor to implement the aircraft cabin pressure monitoring method; the aircraft cabin pressure monitoring equipment can be a terminal, such as a mobile phone or a tablet computer, and the aircraft cabin pressure monitoring equipment can also be a server, or a service cluster consisting of multiple servers.

[0089] like Figure 1 As shown, Figure 1 This is a scenario diagram of the aircraft cabin pressure monitoring method in an embodiment of the present application. The aircraft cabin pressure monitoring scenario in the embodiment of the present invention includes an aircraft cabin pressure monitoring device 100 (the aircraft cabin pressure monitoring device 100 is integrated with an aircraft cabin pressure monitoring device), and the aircraft cabin pressure monitoring device 100 runs a computer-readable storage medium corresponding to aircraft cabin pressure monitoring to execute the steps of aircraft cabin pressure monitoring.

[0090] It is understandable that Figure 1 The aircraft cabin pressure monitoring equipment in the scenario of the aircraft cabin pressure monitoring method shown, or the devices included in the aircraft cabin pressure monitoring equipment, do not constitute a limitation on the embodiments of the present invention. That is, the number and type of equipment included in the scenario of the aircraft cabin pressure monitoring method, or the number and type of devices included in each equipment, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed for protection in the embodiments of the present invention.

[0091] In the embodiment of the present invention, an aircraft cabin pressure monitoring device 100 is provided, and the image profile management device 100 is mainly used to: collect the cabin pressure of the target aircraft to be monitored; calculate the cabin altitude of the target aircraft based on the cabin pressure; and obtain cabin pressure monitoring information of the target aircraft based on the preset flight envelope of the target aircraft and the cabin altitude.

[0092] In the embodiments of the present invention, the aircraft cabin pressure monitoring device 100 may be a standalone aircraft cabin pressure monitoring device, or may be a network of aircraft cabin pressure monitoring devices or a cluster of aircraft cabin pressure monitoring devices. For example, the aircraft cabin pressure monitoring device 100 described in the embodiments of the present invention includes, but is not limited to, a computer, a network host, a single network aircraft cabin pressure monitoring device, a cluster of multiple network aircraft cabin pressure monitoring devices, or a cloud aircraft cabin pressure monitoring device composed of multiple aircraft cabin pressure monitoring devices. The cloud aircraft cabin pressure monitoring device is composed of a large number of computers or network aircraft cabin pressure monitoring devices based on cloud computing.

[0093] Those skilled in the art will understand that Figure 1 The application environment shown in the figure is only one application scenario of the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or fewer aircraft cabin pressure monitoring devices as shown in , or aircraft cabin pressure monitoring device network connection relationships, such as Figure 1 Only one aircraft cabin pressure monitoring device is shown. It is understandable that the scenario of the aircraft cabin pressure monitoring method may also include one or more other aircraft cabin pressure monitoring devices, which are not specifically limited here; the aircraft cabin pressure monitoring device 100 may also include a memory for storing data related to aircraft cabin pressure monitoring.

[0094] Furthermore, in the context of the aircraft cabin pressure monitoring method of the present application, the aircraft cabin pressure monitoring device 100 may be provided with a display device, or the aircraft cabin pressure monitoring device 100 may not be provided with a display device but may be communicatively connected to an external display device 200. The display device 200 is used to output the results of the aircraft cabin pressure monitoring method executed by the aircraft cabin pressure monitoring device. The aircraft cabin pressure monitoring device 100 may access a backend database 300 (the backend database may be located in the local memory of the aircraft cabin pressure monitoring device or may be located in the cloud), which stores information related to aircraft cabin pressure monitoring.

[0095] It should be noted that Figure 1 The scenario diagram of the aircraft cabin pressure monitoring method shown is merely an example. The scenario of the aircraft cabin pressure monitoring method described in the embodiment of the present invention is intended to more clearly illustrate the technical solution of the embodiment of the present invention and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.

[0096] Based on the scenario of the above-mentioned aircraft cabin pressure monitoring method, an embodiment of the aircraft cabin pressure monitoring method is proposed.

[0097] like Figure 2 As shown, Figure 2 This is a flow chart of an embodiment of a method for monitoring aircraft cabin pressure in an embodiment of the present application, specifically including steps 201 to 203:

[0098] 201 , collecting the cabin pressure of the target aircraft to be monitored.

[0099] The aircraft cabin pressure monitoring method in this embodiment is applied to an aircraft cabin pressure monitoring device. The aircraft cabin pressure monitoring device refers to an electronic device used to collect aircraft cabin pressure, calculate and analyze the aircraft cabin pressure, and realize aircraft cabin pressure monitoring. The aircraft cabin pressure monitoring device in the embodiment of the present application is not set on the monitoring instrument panel of the aircraft, but is a mobile terminal that exists independently of the aircraft. After authorization, the mobile terminal can communicate with the aircraft monitoring instrument. The type of aircraft cabin pressure monitoring device is not specifically limited. For example, the aircraft cabin pressure monitoring device is a mobile phone or a tablet.

[0100] In this embodiment, the aircraft cabin pressure monitoring device includes an air pressure acquisition component. For example, if the aircraft cabin pressure monitoring device is an Apple iPad Air tablet, the device uses a barometer to collect the cabin pressure of the target aircraft. The barometer in the aircraft cabin pressure monitoring device detects air pressure based on the principle that atmospheric pressure varies with altitude, with higher altitudes causing lower atmospheric pressure. Furthermore, the aircraft cabin pressure monitoring device includes a temperature sensor that measures the cabin pressure using temperature to improve the accuracy of the measurement results.

[0101] The aircraft cabin pressure monitoring device receives the aircraft cabin pressure monitoring request. The triggering method of the aircraft cabin pressure monitoring request is not specifically limited. That is, the aircraft cabin pressure monitoring request can be actively triggered by the user, for example, by inputting "cabin pressure collection" on the aircraft cabin pressure monitoring software of the mobile phone to actively trigger the aircraft cabin pressure monitoring request; in addition, the aircraft cabin pressure monitoring request can also be automatically triggered by the aircraft cabin pressure monitoring device, for example, the aircraft cabin pressure monitoring device is pre-set to an invalid communication network when the aircraft cabin pressure monitoring device is connected to the aircraft, or the aircraft cabin pressure monitoring device automatically triggers the aircraft cabin pressure monitoring request when detecting that the aircraft takes off.

[0102] After receiving the cabin pressure monitoring request, the cabin pressure monitoring device collects the cabin pressure of the target aircraft to be monitored, where the target aircraft refers to the aircraft where the cabin pressure monitoring device is located. For example, if the cabin pressure monitoring device is a pilot's mobile phone, the target aircraft refers to the aircraft on which the pilot performs the mission.

[0103] In this embodiment, the aircraft cabin pressure monitoring device collects the aircraft cabin pressure through its own air pressure collection component, without relying on the aircraft's own monitoring instruments. The user can easily view the collected aircraft cabin pressure, making aircraft cabin pressure collection and monitoring more convenient.

[0104] 202. Calculate the cabin altitude of the target aircraft according to the aircraft cabin pressure.

[0105] The aircraft cabin pressure monitoring device performs altitude conversion based on the aircraft cabin pressure to calculate the cabin altitude of the target aircraft. That is, the aircraft cabin pressure monitoring device inputs the aircraft cabin pressure into a preset altitude calculation formula to perform altitude conversion to obtain the cabin altitude of the target aircraft. The preset altitude calculation formula is H=145447*(1-(p / 101.325)^(1 / 5.256)), where H represents the cabin altitude and p represents the cabin pressure.

[0106] That is, in this embodiment, the aircraft cabin pressure monitoring device constructs a preset altitude calculation formula based on the relationship between air pressure and altitude. The aircraft cabin pressure monitoring device converts the aircraft cabin pressure collected by the barometer into an altitude to obtain the aircraft cabin altitude, so as to monitor the cabin altitude of the target aircraft.

[0107] 203 : Obtain cabin pressure monitoring information of the target aircraft according to the preset flight envelope of the target aircraft and the aircraft cabin altitude.

[0108] The aircraft cabin pressure monitoring equipment queries the target aircraft's preset flight envelope. A preset flight envelope is a closed geometric figure that uses parameters such as flight speed, altitude, overload, and ambient temperature as coordinates to represent the aircraft's flight range and operating restrictions. For example, civil transport aircraft use the following flight envelopes: ① The level flight speed envelope primarily specifies the maximum level flight speed and maximum Mach allowed at different altitudes. ② The speed overload envelope primarily specifies the maximum allowable aerodynamic overload corresponding to different flight speeds. For civil transport aircraft, the maximum overload is +2.5 when the high-lift device and landing gear are retracted. ③ The gust overload envelope specifies the maximum allowable overload at different flight speeds when encountering a gust. ④ The flight altitude and ambient temperature envelope specifies the allowable ambient temperature range for the aircraft at different flight altitudes. Usually, the highest standard atmospheric temperature for civil transport aircraft is -14t; the lowest is about -75t: ⑤ The flight altitude and climb rate envelope gives the range of the aircraft's allowable flight rate at different flight altitudes; the flight envelope gives the aircraft's speed, load, temperature and other restrictions when in use. The flight envelope is an important basis for the safe use of the aircraft.

[0109] The aircraft cabin pressure monitoring device determines whether the aircraft cabin altitude and the cabin climb rate exceed a threshold value based on the preset flight envelope of the target aircraft, and outputs flight prompt information, specifically including:

[0110] (1) querying a preset flight envelope of the target aircraft to obtain a cabin altitude threshold in the preset flight envelope;

[0111] (2) comparing the aircraft cabin altitude with a cabin altitude threshold in the preset flight envelope;

[0112] (3) If the cabin altitude of the aircraft does not match the cabin altitude threshold below the flight envelope, outputting a warning message as cabin pressure monitoring information of the target aircraft.

[0113] The aircraft cabin pressure monitoring device queries a preset flight envelope of the target aircraft and obtains a cabin altitude threshold value within the preset flight envelope. The cabin altitude threshold value may be different under different circumstances within the preset flight envelope. For example, the aircraft cabin pressure monitoring device may obtain a specific flight altitude according to the flight speed.

[0114] The aircraft cabin altitude is compared with the cabin altitude threshold to determine whether the aircraft cabin altitude matches the cabin altitude threshold, or whether the cabin rate matches the cabin rate threshold. Matching means that the aircraft cabin altitude and cabin rate are within the allowable range of the aircraft envelope. If the aircraft cabin altitude matches the cabin altitude threshold at the flight altitude, and the cabin rate matches the cabin rate threshold, the aircraft cabin pressure monitoring device determines that the aircraft is in a normal flight state and does not issue a prompt. If the aircraft cabin altitude does not match the target cabin threshold at the flight altitude, the aircraft cabin pressure monitoring device determines that the aircraft is not in a normal flight state and outputs a prompt message.

[0115] If the aircraft cabin altitude matches the cabin altitude threshold, the cabin rate of the target aircraft is calculated based on the aircraft cabin altitude. That is, the aircraft cabin pressure monitoring device performs a time differentiation on the aircraft cabin altitude to calculate the cabin rate of the target aircraft. That is, the aircraft cabin pressure monitoring device obtains the aircraft cabin altitude collected during a preset time period, differentiates the aircraft cabin altitude according to the preset time period, and obtains the cabin rate. The cabin rate Δh = (|H2-H1| / |t2-t1|)*60, where Δh represents the cabin rate, t2-t1 represents the preset time period, H2 represents the aircraft cabin altitude at time t2, and H1 represents the aircraft cabin altitude at time t1.

[0116] The aircraft cabin pressure monitoring device compares the target aircraft's cabin rate with a cabin rate threshold in a preset flight envelope. The cabin rate threshold is flexibly set based on the aircraft model. If the target aircraft's cabin rate does not match the cabin rate threshold in the preset flight envelope, an early warning message is output as cabin pressure monitoring information for the target aircraft.

[0117] In this embodiment, the aircraft cabin pressure monitoring device calculates the rate of change per unit time based on the aircraft cabin altitude to obtain the cabin altitude rate of the target aircraft. The aircraft cabin pressure monitoring device monitors the aircraft flight status based on the aircraft cabin altitude and the cabin altitude rate, making the monitoring more comprehensive.

[0118] In the embodiment of the present application, the aircraft cabin pressure monitoring device collects aircraft cabin pressure, calculates the cabin altitude during flight based on the aircraft cabin pressure, and then implements aircraft cabin pressure monitoring in combination with the flight envelope, cabin altitude, and cabin climb rate, thereby improving the convenience and accuracy of aircraft cabin pressure monitoring. At the same time, the user can set the aircraft envelope, making aircraft cabin pressure monitoring more flexible while ensuring flight safety.

[0119] like Figure 3 As shown, Figure 3 The present invention provides a flowchart of an embodiment of aircraft cabin pressure monitoring in an aircraft cabin pressure monitoring method provided in an embodiment of the present application.

[0120] In this embodiment, the aircraft cabin pressure monitoring method couples the aircraft cabin altitude and the flight altitude to monitor the aircraft pressurization. Specifically, the method includes steps 301 to 304:

[0121] 301. Obtain the acquisition time of the aircraft cabin pressure and the flight altitude data of the target aircraft at the acquisition time.

[0122] The aircraft cabin pressure monitoring device obtains the collection time of the aircraft cabin pressure, and the aircraft cabin pressure monitoring device obtains the flight altitude data of the target aircraft at the collection time.

[0123] 302 : Couple the flight altitude data and the aircraft cabin altitude according to the acquisition time to obtain the pressure difference between the inside and outside of the aircraft.

[0124] The aircraft cabin pressure monitoring equipment couples the flight altitude data and the aircraft cabin altitude according to the collection time. That is, the aircraft cabin pressure monitoring equipment calculates the extra-cabin pressure corresponding to the flight altitude data based on the flight altitude data. The aircraft cabin pressure monitoring equipment associates the aircraft cabin altitude and flight altitude data corresponding to the same collection time, and compares the aircraft cabin pressure and extra-cabin pressure corresponding to the associated aircraft cabin altitude and flight altitude data to obtain the pressure difference between the inside and outside of the aircraft.

[0125] 303 , arranging the internal and external pressure differences of the aircraft according to the order of the internal and external pressure differences of the aircraft corresponding to the acquisition time, to obtain a pressure difference change curve of the target aircraft.

[0126] The aircraft cabin pressure monitoring device obtains the collection time corresponding to the internal and external pressure differences of each aircraft, and arranges the internal and external pressure differences of each aircraft in the order corresponding to the collection time to obtain a pressure differential change curve of the target aircraft.

[0127] 304 : Compare the pressure difference change curve with a preset standard curve. If the pressure difference change curve does not match the preset standard curve, output an aircraft pressurization abnormality prompt.

[0128] The aircraft cabin pressure monitoring device compares the pressure differential change curve with a preset standard curve to determine whether the aircraft's pressurization performance is normal. That is, the aircraft's pressurization system will pressurize the aircraft cabin according to the aircraft's flight altitude and real-time environmental information. The aircraft will collect statistics on the standard pressurization data to form a preset standard curve; if the pressure differential change curve matches the preset standard curve, the aircraft cabin pressure monitoring device determines that the aircraft's pressurization performance is normal; if the pressure differential change curve does not match the preset standard curve, the aircraft cabin pressure monitoring device will output an aircraft pressurization abnormality prompt.

[0129] In this embodiment, the aircraft cabin pressure monitoring device calculates the internal and external pressure difference between the aircraft cabin pressure and the aircraft cabin pressure in real time. The aircraft cabin pressure monitoring device determines whether the aircraft pressurization performance is normal based on the internal and external pressure difference. In this way, aircraft pressurization monitoring is realized based on aircraft cabin pressure collection, making aircraft cabin pressure monitoring more comprehensive.

[0130] For ease of understanding, this embodiment provides an example of a specific implementation scenario of an aircraft cabin pressure monitoring device performing cabin pressure monitoring, including:

[0131] The iPad Air is used as an example to illustrate aircraft cabin pressure monitoring equipment. The barometer used in the iPad Air is more accurate than the aircraft cabin pressure, a fact confirmed through comparison with multiple devices. The iPad Air uses a mathematical formula to convert cabin pressure to cabin altitude. By selecting an appropriate time differential interval, changes in cabin altitude are converted to cabin altitude rate. The cabin altitude formula is H = 145447 * (1-(p / 101.325)^(1 / 5.256)), where P is the sampled pressure (kPa) and H is the cabin altitude (feet). The altitude rate formula is Δh = (|H2-H1| / |t2-t1|) * 60, where H2 is the cabin altitude at t2 and H1 is the cabin altitude at t1. The iPad Air adjusts the sensitivity of the change based on the time difference between t2 and t1. Currently, testing shows that t2-t1 = 6 is considered suitable. Air pressure data is collected using the iPad Air's built-in barometer and converted into cabin altitude and cabin rate of climb using the above formula for visualization. Cabin altitude and rate of climb warnings are set based on the aircraft's designed pressurization envelope. The cabin altitude warning is set to the default of 6,000 feet and a custom setting, and the rate of climb warning is set to 1,000 feet per minute.

[0132] The IPAD AIR app can upload previous cabin altitude data and rate of change data to the server when the device is connected to WIFI. By binding the IPAD device to the pilot, the flight segment of the pilot's mission can be obtained. By matching the cabin altitude uploaded by the IPAD with the flight segment executed by the pilot, the cabin altitude of the flight can be obtained. At the same time, by comparing the cabin altitude data uploaded by different pilots in the same flight segment, the background can be verified for the cabin altitude data of the same segment, and IPAD device failures can be discovered in a timely manner to ensure the accuracy of data collection. The flight's altitude data can also be obtained from the Quick Access Recorder (QAR) (a protected airborne flight data recorder, or FDR) for this flight segment. QARs are a crucial onboard electronic device that records aircraft flight parameters. They can continuously record up to 600 hours of raw flight data, collecting hundreds or even thousands of different flight parameters simultaneously. The QAR records data covering the vast majority of aircraft flight parameters, such as latitude and longitude, altitude, wind speed, wind direction and angle of attack, fuel consumption, temperature, and air pressure. By coupling this altitude data with cabin altitude data over time, the pressure differential between the interior and exterior of the aircraft and its changing curve can be determined. Monitoring this curve allows for understanding and monitoring of the aircraft's pressurization performance.

[0133] like Figure 4 As shown, Figure 4The present invention provides a flowchart of an embodiment of an aircraft cabin pressure monitoring method for monitoring the flight mission execution of a target flight crew based on the aircraft cabin pressure.

[0134] In some embodiments of the present application, the aircraft cabin pressure monitoring method further includes the following steps 401 to 404:

[0135] 401, obtaining the cabin altitude and cabin ascent / descent rate of each aircraft when the target flight crew performs the flight mission.

[0136] The aircraft cabin pressure monitoring equipment obtains the cabin altitude and cabin ascent / descent rate of each aircraft when the target flight crew performs a flight mission.

[0137] 402 , sort the cabin altitudes of the aircraft in chronological order to form a cabin altitude sequence, and sort the cabin ascent and descent rates in chronological order to form a ascent and descent rate sequence.

[0138] The aircraft cabin pressure monitoring device sorts the aircraft cabin altitudes and altitude climbing rates of each target flight crew member when performing a flight mission. That is, the aircraft cabin pressure monitoring device sorts the aircraft cabin altitudes in chronological order to form a cabin altitude sequence, and sorts the cabin climbing rates in chronological order to form a climbing rate sequence.

[0139] 403 : Compare the cabin altitude sequence with a target cabin altitude at a preset standard flight altitude, and compare the ascent and descent rate sequence with a preset standard ascent and descent rate.

[0140] The aircraft cabin pressure monitoring device compares the cabin altitude sequence with a preset standard flight altitude, and compares the lift rate sequence with a preset standard lift rate to determine whether the target flight crew performs the flight mission in compliance with the rules; if the cabin altitude sequence matches the preset standard flight altitude, and the lift rate sequence matches the preset standard lift rate, it is determined that the target flight crew performs the flight mission well.

[0141] 404 , if the cabin altitude sequence does not match the preset standard flight altitude, and / or the ascent and descent rate sequence does not match the preset standard ascent and descent rate, output a prompt message.

[0142] If the cabin altitude sequence does not match the preset standard flight altitude, and / or the rate of ascent sequence does not match the preset standard rate of ascent, the aircraft cabin pressure monitoring device determines that the target flight crew's flight mission execution can be optimized and outputs a prompt message. In this embodiment, the aircraft cabin pressure monitoring device can monitor the flight mission based on the cabin altitude sequence and rate of ascent sequence corresponding to the target flight crew, allowing the target flight crew to understand their own flight data.

[0143] Reference Figure 5 , Figure 5 1 is a flow chart of an embodiment of aircraft cabin pressure accuracy determination in an aircraft cabin pressure monitoring method provided in an embodiment of the present application.

[0144] In some embodiments of the present application, after the aircraft cabin pressure is measured, the aircraft cabin pressure monitoring device determines whether the aircraft cabin pressure is accurate, including the following steps 501 to 502:

[0145] 501, receiving a reference cabin pressure of the target aircraft sent by a preset terminal, and comparing the aircraft cabin pressure with the reference cabin pressure;

[0146] 502 : If the aircraft cabin pressure does not match the reference cabin pressure, output a prompt message indicating that the aircraft cabin pressure monitoring is abnormal.

[0147] The aircraft cabin pressure monitoring device receives a reference cabin pressure of a target aircraft sent by a preset terminal, where the preset terminal refers to an electronic device other than the aircraft cabin pressure monitoring device that can collect aircraft cabin pressure. The aircraft cabin pressure monitoring device compares the aircraft cabin pressure with the reference cabin pressure. If the aircraft cabin pressure matches the reference cabin pressure, the aircraft cabin pressure monitoring device determines that the collected aircraft cabin pressure is correct. If the aircraft cabin pressure does not match the reference cabin pressure, the aircraft cabin pressure monitoring device determines that the collected aircraft cabin pressure is incorrect and outputs a prompt message indicating that the aircraft cabin pressure monitoring is abnormal.

[0148] In this embodiment, the aircraft cabin pressure monitoring device compares the aircraft cabin pressure collected by the aircraft cabin pressure monitoring device with a reference cabin pressure. If the aircraft cabin pressure and the reference cabin pressure do not match, a prompt can be given. This does not require subsequent data processing, making aircraft cabin pressure monitoring more intelligent.

[0149] Reference Figure 6 , Figure 6 1 is a flow chart of an embodiment of aircraft cabin altitude monitoring in an aircraft cabin pressure monitoring method provided in an embodiment of the present application.

[0150] In some embodiments of the present application, it is specifically described that the aircraft cabin pressure monitoring method further includes the following steps 601 to 603:

[0151] 601. Obtain the target time corresponding to the aircraft cabin altitude and the standard cabin altitude corresponding to the target time.

[0152] 602, comparing the aircraft cabin altitude with the standard cabin altitude;

[0153] 603. If the aircraft cabin altitude does not match the standard cabin altitude, output a prompt message indicating that the aircraft cabin altitude is abnormal.

[0154] The cabin pressure monitoring device obtains the target time corresponding to the aircraft cabin altitude and the reference cabin altitude corresponding to the target time. The reference cabin altitude refers to a pre-set reference cabin altitude for the cabin pressure monitoring device. The cabin pressure monitoring device compares the cabin altitude with the reference cabin altitude. If the reference cabin altitude and the aircraft cabin altitude match, no action is taken. If the reference cabin altitude and the aircraft cabin altitude do not match, a prompt indicating an abnormal cabin altitude is output. In this embodiment, the cabin pressure monitoring device can monitor the aircraft cabin altitude in real time, enabling more comprehensive monitoring of the aircraft's flight status through cabin pressure monitoring.
