Description

Technical Field

[0001] The present invention relates to the technical field of aircraft health management, and more particularly to a method and system for determining life cycle data of airborne electronic equipment. Background Art

[0002] Life cycle data refers to the cumulative time that electronic equipment of a specific configuration continues to work normally on different aircraft and in different flight segments, which includes the initial operating time (operating time before the current segment) and the onboard operating time of this segment.

[0003] The life cycle data of airborne electronic equipment plays an important role in the operation of aircraft. Specifically, during the route maintenance process, life cycle data can help maintenance engineers and maintenance personnel prepare maintenance plans in advance, effectively shorten maintenance time and improve economy. In addition, life cycle data can be used to accumulate data on the reliability of electronic equipment operation, and is also an important basis for airlines to make equipment warranty reliability claims. Statistical analysis shows that the failure rate of a certain configuration of airborne displays will increase significantly after more than 20,000 flight hours, and when it reaches 28,000 to 30,000 flight hours, the life span almost reaches the limit. Therefore, airlines using airborne displays of this configuration can make targeted predictions and reserves to avoid being affected by concentrated outbreaks or major guarantees. In terms of preventive repairs, the failure of airborne electronic equipment is often hidden and requires complex testing equipment and processes. Therefore, it is very important to continuously accumulate usage experience. Good data statistics and analysis can provide guidance for aircraft selection and repair.

[0004] The airborne electronic equipment on traditional aircraft is designed a long time ago, and its life cycle data is only stored inside the equipment itself. When the equipment is returned to the factory for maintenance, it needs to be read through special data analysis tools or special equipment, which is difficult for airlines to obtain. As a result, airlines or maintenance personnel can only rely on manual records (that is, they need to manually record the time of each flight segment) and combine the ground auxiliary system to accumulate year by year to manually record and obtain the life cycle data of electronic equipment. The work efficiency is low, the cost of obtaining data is high, and the convenience and economy are not good.

[0005] The methods for calculating the life cycle data of onboard electronic equipment in the prior art consider the scenario where the electronic equipment is installed on the same aircraft. However, in actual practice, there are scenarios where electronic equipment is installed across aircraft. The existing methods do not consider the scenario where the same electronic equipment is installed on different aircraft, making the calculated life cycle data incomplete and inaccurate.

[0006] In view of this, it is desirable to provide an improved technical solution for determining life cycle data of airborne electronic equipment to improve the integrity and accuracy of the life cycle data. Summary of the invention

[0007] A brief summary of one or more aspects is given below to provide a basic understanding of these aspects.

[0009] In some embodiments, the onboard configuration manifest is received from the maintenance system of the aircraft after the maintenance system is powered on and stabilized.

[0010] In some embodiments, comparing the configuration of each airborne electronic device with the ground configuration list further includes: comparing the configuration of the airborne electronic device with the configuration of each electronic device in the ground configuration list to determine whether the configuration of the airborne electronic device is included in the ground configuration list.

[0011] In some embodiments, determining the initial operating time of each airborne electronic device based on the comparison result further includes: if the configuration of the airborne electronic device is included in the ground configuration list, setting the initial operating time of the airborne electronic device to the operating time of the corresponding electronic device recorded by the ground database; and if the configuration of the airborne electronic device is not included in the ground configuration list, setting the initial operating time of the airborne electronic device to 0.

[0012] In some embodiments, determining the segment operation time of each airborne electronic device further includes: obtaining characteristic parameters transmitted by the airborne electronic device in the current segment; and determining the segment operation time of the airborne electronic device based on the period and transmission times of the characteristic parameters.

[0013] In some embodiments, the method further includes: selecting one or more airborne electronic devices from among all airborne electronic devices; outputting and displaying life cycle data of the selected one or more airborne electronic devices.

[0014] In some embodiments, after the current flight segment ends, the life cycle data of all airborne electronic equipment is transmitted to the ground database for updating.

[0015] The present invention also provides a system for determining the life cycle data of airborne electronic equipment, including: an onboard configuration list acquisition module, which is configured to: acquire the onboard configuration list of the aircraft, the onboard configuration list includes the configuration of all airborne electronic equipment currently on the aircraft, and the configuration includes the identification, part number, and serial number of the corresponding airborne electronic equipment; a database information acquisition module, which is configured to: acquire the ground configuration list and operating time information of the aircraft from the ground database before the start of the current flight segment, the ground configuration list includes the configuration of the electronic equipment contained in the aircraft recorded by the ground database, and the operating time information includes the operating time of each electronic equipment recorded by the ground database; a configuration comparison module, which is configured to: compare each airborne electronic equipment The configuration of the electronic device is compared with the ground configuration list; an initial operation time determination module is configured to: determine the initial operation time of each airborne electronic device based on the comparison result, and the initial operation time represents the operation time of the corresponding airborne electronic device before the current flight segment; a segment operation time determination module is configured to: determine the segment operation time of each airborne electronic device, and the segment operation time represents the operation time of the corresponding airborne electronic device in the current flight segment; and a life cycle data determination module is configured to: determine the life cycle data of each airborne electronic device based on the initial operation time and the segment operation time of each airborne electronic device, and the life cycle data includes the configuration and accumulated operation time of the corresponding airborne electronic device.

[0025] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to provide a thorough understanding of the described exemplary embodiments. However, it is obvious to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other exemplary embodiments, well-known structures are not described in detail to avoid unnecessarily obscuring the concepts of the present disclosure. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. At the same time, in the absence of conflict, the various aspects described in the embodiments can be combined arbitrarily.

[0026] Figure 1 A schematic diagram 100 of life cycle data of airborne electronic equipment in a cross-machine installation scenario is shown.

[0027] During route operations, airborne electronic equipment may be installed across aircraft.

[0028] like Figure 1 As shown, the onboard electronic device 1 is initially installed on the aircraft 1 and has been in operation on the aircraft 1 for T0 hours.

[0029] Afterwards, the airborne electronic device 1 was disassembled and installed across the aircraft to the aircraft 2, and the T Op Hour.

[0030] For airborne electronic equipment 1, its complete life cycle data should be T0+T Op However, conventional life cycle data calculation methods often only calculate the operating time of the onboard electronic device 1 on the aircraft 2. The operating time data T0 of the onboard electronic device 1 before cross-machine installation on the aircraft 2 is often easily ignored. This makes it difficult to obtain and record the complete life cycle data of the onboard electronic device.

[0031] The present invention enables the aircraft to send the latest life cycle data to the ground system / ground station after the end of each flight segment, and the ground station centrally manages the life cycle data of the airborne electronic equipment, so that the life cycle data of the airborne electronic equipment across various aircraft can be recorded and managed (such as the life cycle data of device 1 across aircraft 1 and aircraft 2), thereby improving the integrity and accuracy of the life cycle data.

[0032] Figure 2 A schematic diagram 200 of a process for calculating life cycle data of an onboard electronic device of the present invention is shown.

[0033] like Figure 2 As shown, the calculation process of the life cycle data of the airborne electronic equipment of the present invention includes several stages.

[0034] During the parameter acquisition phase, characteristic parameters of all airborne electronic equipment may be acquired (for example, via the aircraft avionics network, through hardware direct connection or other means). The characteristic parameters of airborne electronic equipment are parameters that characterize whether the airborne electronic equipment is operating normally, including but not limited to equipment configuration parameter data, status parameter data, etc. Airborne electronic equipment may periodically send corresponding characteristic parameters during normal operation. If the parameters of the airborne electronic equipment can be received, it indicates that the airborne electronic equipment is operating normally. If the characteristic parameters of the airborne electronic equipment are not received, it means that the airborne electronic equipment is not operating or is not operating normally.

[0035] During the initial operating time calculation stage, the configuration of the electronic equipment contained in the aircraft and the operating time of the corresponding electronic equipment recorded in a ground database (for example, located in a ground station) can be obtained, and the configuration of the aircraft's current onboard electronic equipment can be compared with the configuration in the ground database to set / calculate the initial operating time of the onboard electronic equipment.

[0036] In the flight segment operation time calculation stage, the operation time (segment operation time) of the airborne electronic equipment on the aircraft in the current flight segment may be calculated using characteristic parameters of the airborne electronic equipment.

[0037] In the life cycle data calculation phase, the life cycle data of the airborne electronic device may be obtained by accumulating the initial operation time and the flight segment operation time of the airborne electronic device.

[0038] Then, in the output stage, the life cycle data can be output to the HMI page in the form of graphics or text. The display format includes but is not limited to ARINC661 format, Web format, etc.

[0039] The above shows the calculation process of the life cycle data of airborne electronic equipment, but it should be noted that Figure 2 The division of each stage of the calculation process and the operations performed are only exemplary and not restrictive. In actual implementation, those skilled in the art may use different methods to implement the calculation process of the life cycle data of the airborne electronic device.

[0040] Figure 3 A method 300 of the present invention for determining life cycle data of onboard electronic equipment is shown.

[0041] like Figure 3 As shown, method 300 starts at step 305. At step 305, the onboard configuration list of the aircraft is obtained, and the onboard configuration list includes the configuration of all current onboard electronic equipment on the aircraft, and the configuration includes the identification, part number, and serial number of the corresponding onboard electronic equipment.

[0042] In some embodiments of the present invention, the onboard configuration list is received from the maintenance system after the maintenance system of the aircraft is powered on and stabilized. The onboard electronic equipment included in the onboard configuration list includes the onboard electronic equipment actually installed on the current aircraft.

[0043] The onboard electronic device can be uniquely identified by the identification, part number and serial number of the onboard electronic device contained in the configuration of the onboard configuration list.

[0044] It should be noted that the information included in the configuration is not limited to the identification, part number, and serial number of the onboard electronic device. In actual implementation, the configuration may also include other information of the corresponding onboard electronic device.

[0045] In step 310, before the current flight segment begins, the ground configuration list and operating time information of the aircraft are obtained from the ground database. The ground configuration list includes the configuration of the electronic equipment included in the aircraft recorded by the ground database, and the operating time information includes the operating time of each electronic equipment recorded by the ground database.

[0046] The configuration and operation time information of the electronic equipment included in the aircraft included in the ground configuration list is recorded by the ground database before the current flight segment (for example, transmitted by the aircraft to the ground database). Due to the time difference between the recording time and the current time, the information recorded in the database may deviate from the actual information of the aircraft. For example, after the ground database last recorded the information of the aircraft, the aircraft may have disassembled some onboard electronic equipment and / or installed new onboard electronic equipment. Therefore, the onboard configuration list may include configuration information that is not in the ground configuration list.

[0047] At step 315, the configuration of each onboard electronic device is compared with the ground configuration list.

[0048] Specifically, for each airborne electronic device on the aircraft, the configuration of the airborne electronic device may be compared with the configuration of each electronic device in the ground configuration list to determine whether the configuration of the airborne electronic device is included in the ground configuration list.

[0049] For example, the identification, part number, and serial number of the onboard electronic equipment may be compared one by one with the identification, part number, and serial number of each electronic equipment in the ground configuration list.

[0050] If the identification, part number, and serial number are found to match after comparison, it means that the corresponding airborne electronic equipment is included in the ground configuration list (that is, the ground database has previously recorded the relevant information of the airborne electronic equipment).

[0051] If the comparison finds that the identification, part number, and serial number do not match, it means that the corresponding airborne electronic equipment is not included in the ground configuration list (that is, the ground database has not yet recorded the relevant information of the airborne electronic equipment).

[0052] In step 320, the initial operating time of each onboard electronic device is determined based on the comparison result, where the initial operating time indicates the operating time of the corresponding onboard electronic device before the current flight segment.

[0053] Specifically, for each airborne electronic device, if it is found through comparison that the configuration of the airborne electronic device is included in the ground configuration list, it means that the airborne electronic device has been operated before and the ground database has recorded the configuration and the operating time of the airborne electronic device. At this time, the initial operating time of the airborne electronic device can be set to the operating time of the corresponding electronic device recorded by the ground database.

[0054] If it is found through comparison that the configuration of the airborne electronic equipment is not included in the ground configuration list, it means that the airborne electronic equipment has not been operated yet (for example, it is a newly installed airborne electronic equipment and has not been operated on other aircraft) and the ground database does not have the configuration and operating time of the airborne electronic equipment. At this time, the initial operating time of the airborne electronic equipment can be set to 0.

[0055] In step 325, the segment operation time of each onboard electronic device is determined, where the segment operation time indicates the operation time of the corresponding onboard electronic device in the current segment.

[0056] Specifically, for each airborne electronic device, characteristic parameters transmitted by the airborne electronic device in the current flight segment may be obtained, and the flight segment operation time of the airborne electronic device may be determined based on the period and transmission times of the characteristic parameters.

[0057] As mentioned above, the characteristic parameters of the airborne electronic equipment are parameters that characterize whether the airborne electronic equipment is operating normally. In the case of normal operation, the airborne electronic equipment periodically sends the corresponding characteristic parameters. When the airborne electronic equipment is not operating, the characteristic parameters are not sent.

[0058] Therefore, in the current flight segment, the characteristic parameters of the airborne electronic equipment can be continuously monitored and collected, the number of times the characteristic parameters are collected can be determined, and the number of times is multiplied by the period of the characteristic parameters to obtain the operating time of the airborne electronic equipment in the current flight segment (segment operating time).

[0059] It should be noted that although the use of characteristic parameters to determine the segment running time of the airborne electronic device is described herein, the present invention is not limited thereto. In some cases, the airborne electronic device itself has a time calculation module and can calculate the segment running time by itself through the time calculation module. In such a case, the segment running time of the airborne electronic device can be directly obtained from the time calculation module of the airborne electronic device.

[0060] In step 330 , life cycle data of each onboard electronic device is determined based on the initial operation time and the flight segment operation time of each onboard electronic device, where the life cycle data includes the configuration and accumulated operation time of the corresponding onboard electronic device.

[0061] After obtaining the initial operation time and the flight segment operation time of the airborne electronic device, the two can be accumulated to obtain the cumulative operation time of the airborne electronic device. If the airborne electronic device is initially installed on the current aircraft, the cumulative operation time indicates the operation time of the airborne electronic device on the current aircraft. If the airborne electronic device is installed from another aircraft to the current aircraft, the cumulative operation time indicates the operation time of the airborne electronic device on all aircraft.

[0062] After determining the life cycle data of the airborne electronic equipment, the life cycle data can be output ( Figure 3 (not shown in the figure). Specifically, one or more airborne electronic devices among all airborne electronic devices can be selected, and the life cycle data of the selected one or more airborne electronic devices can be output and displayed. For example, one or more airborne electronic devices can be selected on the panel of the aircraft, and then the life cycle data of the selected airborne electronic devices can be displayed on the display device of the aircraft. In this way, maintenance personnel or aircraft maintenance personnel can know accurate and complete life cycle data of airborne electronic devices.

[0063] After the current flight segment ends, the life cycle data of all onboard electronic equipment can also be transmitted to the ground database for updating. In this way, the ground station can centrally manage the life cycle data.

[0064] Figure 4 An example 400 of determining lifecycle data of onboard electronic equipment using the method of the present invention is shown.

[0065] like Figure 4 As shown, after the aircraft maintenance system is powered on, the current state of the maintenance system can be determined by first judging whether the maintenance system has a stable output within three cycles.

[0066] If the maintenance system has a stable output within 3 cycles, it means that the maintenance system is stable at this time. If the maintenance system output is unstable within 3 cycles, it means that the maintenance system is not stable at this time. At this time, you can wait and continue to judge until the maintenance system is stable. Note that the number of cycles (3 cycles) shown here is only an example and not a limitation. In a specific implementation, other numbers of cycles may also be used, such as 4 cycles, 5 cycles, etc.

[0067] When the maintenance system is stable, the current configuration information of the entire aircraft electronic equipment can be received from the maintenance system. For example, the maintenance system can provide an on-board configuration list, which includes the configuration of all on-board electronic equipment on the current aircraft.

[0068] In addition, the ground configuration list and the corresponding time value (elapsed time) stored can be obtained before the flight (before the current flight segment starts). For example, the ground configuration list and running time information of the aircraft are stored in the ground database of the ground station. The ground configuration list includes the configuration of the electronic equipment included in the aircraft recorded by the ground database, and the running time information includes the running time of each electronic equipment recorded by the ground database. Thus, a request can be sent to the ground station, and the ground configuration list and running time value uploaded by the ground station in response to the request can be received.

[0069] Next, it may be determined whether the current configuration of the onboard electronic equipment is included in the ground configuration list.

[0070] If the current configuration of the onboard electronic equipment is included in the ground configuration list, the initial operation time is set to the time value uploaded from the ground station. If the current configuration of the onboard electronic equipment is not included in the ground configuration list, the initial operation time is set to 0.

[0071] Then, the operating time of the onboard electronic device on the aircraft in the current flight segment (segment operating time) can be calculated. By superimposing the initial operating time with the segment operating time, the life cycle data of the onboard electronic device can be obtained.

[0072] After the life cycle data is calculated, the life cycle data may be output (eg, output to an HMI page for display).

[0073] In addition, the life cycle data of all onboard electronic equipment can be transmitted to the ground station after the flight (after the current flight segment ends) for the ground database to update. The updated data can be read and used for the next flight segment.

[0074] By using ground stations and ground databases to centrally manage life cycle data, the recorded life cycle data is provided to the aircraft before the start of each flight segment, the current life cycle data of the airborne electronic equipment is calculated during the flight segment, and the ground database is updated with the latest life cycle data after the flight segment. Accurate and complete life cycle data can be calculated in both single-machine and cross-machine installation scenarios of airborne electronic equipment.
