Description

{AIRCRAFT HEALTH MANAGEMENT APPARATUS AND THE METHOD THEREOF}

The present invention relates to an aircraft health management device and method thereof, and more specifically, to an aircraft health management device and method thereof capable of stably managing the health of an aircraft.

The main causes of aircraft accidents are aircraft defects, human factors, and natural disasters. In order to prevent aircraft accidents caused by aircraft defects, aircraft must maintain airworthiness.

In the past, before the start of aircraft operation and after the end of aircraft operation, the fuselage and electronic equipment mounted on the aircraft were performed. In order to repair abnormal electronic equipment that generates abnormal operation data among the electronic equipment, maintenance data for repairing the abnormal electronic equipment is required. This maintenance data is generated and used by a pre-determined program, but since the maintenance data cannot be verified, if there is an error in the maintenance data, a defect may occur again in the repaired abnormal electronic equipment.

In addition, electronic equipment mounted on aircraft may temporarily exhibit abnormal operation due to other electronic equipment connected to it, even if it has not yet developed a defect. However, maintenance data is currently not generated by considering the abnormal operation of electronic equipment, and only maintenance is performed on electronic equipment that has developed a defect, which creates a problem in that the aircraft health cannot be stably managed.

FIG. 1 is a block diagram schematically showing an aircraft health management device according to an embodiment of the present invention, and FIG. 2 is a block diagram showing a detailed structure of an aircraft health management device according to an embodiment of the present invention.

Referring to FIG. 1, an aircraft health management device may include an analysis unit (120) that is installed in an aircraft (10, see FIG. 2) and that can detect abnormal operation data among operation data collected from electronic devices (A, B1, ..Bn, see FIG. 2) mounted on the aircraft (10) after the start of operation of the aircraft (10) and abnormal electronic devices that have generated the abnormal operation data among the collected operation data, and can generate maintenance data for the abnormal electronic devices, and a verification unit (130) that is installed outside of the aircraft (10) and can verify whether the maintenance data is normal after the end of operation of the aircraft (10), that is, an error in the maintenance data, and can be connected to the analysis unit (120).

In addition, the aircraft health management device may further include a collection unit (110) connected to electronic devices (A, B1,...Bn) and an analysis unit (120) to collect operational data, a transmission unit (not shown) that can be connected to the analysis unit (120) and the verification unit (130) to transmit the operational data and maintenance data to the verification unit (130), and an output unit (140) that can provide the maintenance data so that the operator can check it.

Referring to FIG. 2, the collection unit (110) can connect the electronic devices (A, B1,...Bn) and the analysis unit (120) so that the operational data generated from the electronic devices (A, B1,...Bn) can be transmitted to the analysis unit (120). The collection unit (110) can include a first collector (111) that can be connected to a first electronic device (A) that can be detachably installed on an aircraft (10) among the electronic devices (A, B1,...Bn), and a second collector (112: 112-a,...112-n) that can be connected to a second electronic device (B1,...Bn) that is fixedly installed on the aircraft (10). In FIG. 2, the first electronic device (A) is illustrated as one, but there may be multiple first electronic devices (As), and in this case, the first collector (111) may be provided in the same number as the first electronic devices (A).

The combined number of the first collector (111) and the second collector (112: 112-a,...112-n) may be equal to the number of electronic devices (A, B1,...Bn), or may be greater than the number of electronic devices (A, B1,...Bn).

When the operation of the aircraft (10) is initiated, the transceiver (121) can receive operational data generated from electronic devices (A, B1,...Bn). At this time, the transceiver (121) is connected to the collection unit (110) and can receive operational data generated from electronic devices (A, B1,...Bn) collected through the collection unit (110).

The operational data may include operational data before takeoff of the aircraft (10), operational data during the flight, and operational data after landing, but is referred to herein as 'operational data'.

An aircraft is driven to take off. Accordingly, the aircraft may be in a driven state before taking off. That is, some of the plurality of components included in the aircraft are in a driven state for takeoff before takeoff. In addition, the aircraft is driven for a predetermined period of time after landing the aircraft. For example, at least some of the components of the aircraft are in a driven state for a predetermined period of time, such as when the aircraft moves along the runway after landing on the runway. Accordingly, operational data of the aircraft can be provided and collected before taking off and after landing the aircraft. In addition, the aircraft is in flight after taking off and before landing. Accordingly, operational data of the aircraft in flight can be provided and collected.

In an embodiment of the present invention, operational data for electronic devices in operation are collected before takeoff, during flight, and after landing. At this time, the operational data for the electronic devices may include at least one of the operating status of the electronic devices, signal output, received signals, and measured values, and the operational data may be different for each electronic device. In addition, the operational data collected for each electronic device may be in at least one of the following forms: numerical, image, and message.

In addition, when maintenance data is generated from the first generator (124), the transmitter/receiver (121) can transmit the maintenance data together with the operation data to the verification unit (130). The maintenance data is data for servicing abnormal electronic equipment that generates abnormal operation data, and can include information on a maintenance method for the abnormal electronic equipment, a maintenance manual such as a maintenance location, etc. Such maintenance data can be prepared as text information, image data, voice data, etc.

The first storage (122) can store the operating data received through the transceiver (121) and the maintenance data generated from the first generator (124). In addition, the first storage (122) can store various data generated from the analysis unit (120). In addition, the first storage (122) can store the reference operating data generated when the electronic devices (A, B1,...Bn) operate normally. The reference operating data may be the same or different for each electronic device. In addition, the reference operating data for each electronic device may be classified and stored as the reference operating data before takeoff, the reference operating data during flight, and the reference operating data after landing, but is referred to herein as the reference operating data. The first storage (122) can classify the operating data, the reference operating data, and the maintenance data by time and by electronic device and store them.

The first explorer (123) can search for abnormal operation data among the operation data received or collected, and abnormal electronic equipment that generates the abnormal operation data. The first explorer (123) compares the collected operation data with the reference operation data stored in the first storage (122) in real time, and selects data in which the operation data deviates from or does not match the reference operation data as abnormal operation data. At this time, the first explorer (123) can compare the operation data with the reference operation data based on various criteria such as time, electronic equipment, etc., and select or search for the abnormal operation data. Here, the operation data deviating from or not matching the reference operation data means that the operation data is different from the reference operation data or is outside a predetermined reference range.

The first explorer (123) can select or search for abnormal operation data, and select or search for abnormal electronic equipment that generates the searched operation data, i.e., abnormal operation data. At this time, the first explorer (123) can search for abnormal electronic equipment using electronic equipment information such as the type and ID of electronic equipment included in the operation data, i.e., abnormal operation data.

The first generator (124) can analyze the abnormal operation data searched or selected by the first explorer (123) to generate maintenance data for abnormal electronic equipment that generates the abnormal operation data. At this time, the first generator (124) can analyze the abnormal operation data to generate maintenance data such as a method and location for servicing the abnormal electronic equipment.

The decision unit (125) can determine whether to maintain the flight of the aircraft (10) by using the reference operation data and the abnormal operation data. If the abnormal operation data significantly exceeds the preset reference range, the decision unit (125) can determine that the abnormal electronic equipment that generates the abnormal operation data is broken or is likely to break down, thereby affecting the flight of the aircraft (10). For example, if the abnormal operation data is included in the preset risk range, the decision unit (125) can predict that the abnormal electronic equipment will act as a risk factor for the flight of the aircraft (10), thereby generating a landing command to instruct an emergency landing of the aircraft (10).

The verification unit (130) can verify whether the maintenance data generated by the analysis unit (120) is normal, i.e., whether there is an error. The verification unit (130) can be installed in a control center, maintenance center, etc., which is located away from the aircraft (10), for example, on the ground. In addition, the verification unit (130) can be installed as a mobile terminal so that it can be used inside and outside the aircraft (10).

The verification unit (130) may include a receiver (131) capable of receiving operation data and maintenance data from the analysis unit (120), a second storage unit (132) capable of storing reference operation data of electronic devices (A, B1,...Bn), a second search unit (133) capable of searching for abnormal electronic devices that have generated abnormal operation data among the electronic devices using the received operation data and reference operation data, a second generator (134) capable of generating verification data for the abnormal electronic devices, and a verification unit (135) capable of comparing the maintenance data with the verification data to determine whether the maintenance data is normal and determining the maintenance data or the verification data as the final maintenance data for the aircraft based on the comparison result.

The receiver (131) can receive operating data and maintenance data from the analysis unit (120). At this time, the receiver (131) can be connected to the transceiver (121) of the analysis unit (120) through the transmission unit.

The second storage (132) can store reference operating data generated when electronic devices (A, B1,...Bn) operate normally. The second storage (132) can store reference operating data for electronic devices that can be installed on each aircraft. The reference operating data can be the same or different for each electronic device, and the reference operating data of electronic devices installed on aircraft to be verified can be the same.

The second explorer (133) can search for abnormal operation data and abnormal electronic equipment that generates abnormal operation data among the operation data transmitted from the analysis unit (120). The second explorer (133) compares the operation data transmitted from the analysis unit (120) with the reference operation data stored in the second storage unit (132), and selects data that deviates from or does not match the reference operation data as abnormal operation data. At this time, the second explorer (133) can compare the operation data and the reference operation data in the same manner as the first explorer (123), and select or search for the abnormal operation data.

In this way, the second explorer (133) can select or search for abnormal operating data and select or search for abnormal electronic equipment that generates the searched operating data, i.e., abnormal operating data.

The second generator (134) can analyze the abnormal operation data searched or selected by the second explorer (133) to generate verification data of the abnormal electronic equipment that generates the abnormal operation data. At this time, the second generator (134) can analyze the abnormal operation data to generate verification data such as a method, location, etc. for servicing the abnormal electronic equipment. Here, the verification data is data for verifying whether the maintenance data transmitted from the analysis unit (120) is normal, and can be identical to or different from the maintenance data.

The verifier (135) can verify whether the maintenance data is normal by comparing the verification data generated from the second generator (134) with the maintenance data transmitted from the analysis unit (120). At this time, if the verification data is identical to the maintenance data, the maintenance data generated from the analysis unit (120) is determined to be normal, and the maintenance data can be determined as the final maintenance data. On the other hand, if the verification data is different from the maintenance data, the maintenance data generated from the analysis unit (120) is determined to be abnormal, and the verification data can be determined as the final maintenance data.

The final maintenance data determined by the verifier (135) can be stored in the second storage (132). In addition, the final maintenance data can be used to maintain abnormal electronic equipment.

In this way, the analysis unit (120) and the verification unit (130) can search for operating data of electronic equipment using standard operating data or search for abnormal electronic equipment that has generated abnormal operating data by using pre-learned artificial intelligence.

Meanwhile, the reason why abnormal operating data is generated from abnormal electronic equipment may be due to a problem with the abnormal electronic equipment itself, or may be due to another electronic equipment connected to the abnormal electronic equipment, such as an abnormal electronic equipment causing an abnormality. Or, may be due to another abnormal electronic equipment causing an abnormality linked to the abnormal electronic equipment causing an abnormality.

Accordingly, the analysis unit (120) can additionally search for abnormal electronic devices that affect the abnormal electronic devices depending on whether there is electronic devices that operate in conjunction with the abnormal electronic devices. In addition, the verification unit (130) can search for abnormal electronic devices in the same manner as the analysis unit (120). At this time, the abnormal electronic devices may be one or more.

The output unit (140) can visualize the data generated by the analysis unit (120) and the verification unit (130) so that the operator or the captain can check them. Accordingly, the output unit (140) can be installed inside the aircraft (10) or installed in the work place so that the operator who maintains the electronic equipment can check them. In addition, the output unit (140) can be installed in the control center that controls the flight of the aircraft (10). This output unit (140) can be provided as a display device that displays or displays maintenance data on abnormal electronic equipment so that the captain or the operator can check them.

FIG. 3 is a flowchart illustrating an aircraft health management method according to an embodiment of the present invention, FIG. 4 is a flowchart illustrating a process of generating maintenance data in an aircraft according to an embodiment of the present invention, and FIG. 5 is a flowchart illustrating a process of verifying maintenance data according to an embodiment of the present invention, among the aircraft health management methods. In the following, any content that overlaps with the previously explained content will be omitted or briefly described.

Referring to FIG. 3, an aircraft health management method according to an embodiment of the present invention may include a process (S120) of collecting operational data generated from electronic equipment mounted on an aircraft, a process (S130) of generating maintenance data for servicing abnormal electronic equipment among the electronic equipment using the operational data, and a process (S150) of verifying errors in the maintenance data.

First, the aircraft is driven for takeoff. That is, the aircraft operation is initiated (S110). Then, operational data is collected from electronic devices mounted on the aircraft (S120), and the collected operational data can be stored in the first storage device (122). The operational data collected at this time is pre-takeoff operational data.

Referring to FIG. 3, when the operation data is collected, the analysis unit (120) can search for abnormal operation data among the operation data (S131), and if the abnormal operation data is searched, it can search for abnormal electronic equipment that generates the abnormal operation data (S133). Then, if the abnormal electronic equipment is searched, the analysis unit (120) can generate maintenance data for servicing the abnormal electronic equipment, and store the generated maintenance data in the first storage unit (122) (S134). At this time, if it is determined (S135) that the abnormal electronic equipment may affect the flight of the aircraft (10), the first generator (124) of the analysis unit (120) can generate a takeoff prohibition order that prohibits the flight of the aircraft (10) and store it in the first storage unit (122) (S136).

On the other hand, if abnormal operation data that may affect the flight of the aircraft (10) or cause an abnormality in the flight is not searched for (S131), the aircraft is taken off and flown. In this way, while the aircraft (10) takes off and flies, the analysis unit (120) continuously collects operation data generated from electronic devices (A, B1,...Bn), and searches for abnormal operation data (S131) using the collected operation data and reference operation data, and can search for abnormal electronic devices that generate the abnormal operation data (S133). In addition, if there is abnormal electronic devices that generate abnormal operation data, maintenance data for the corresponding abnormal electronic devices can be generated (S134).

In addition, if the analysis unit (120) analyzes the abnormal operation data and predicts or determines (S135) that the abnormal electronic equipment will cause an abnormality in the flight of the aircraft (10), it can generate a landing command for an emergency landing of the aircraft (10) and store the generated landing command in the first storage unit (122) (S136). At this time, the landing command can include distance information, direction information, and location information about the nearest landing location from the location where the aircraft (10) is flying. Then, the aircraft (10) can be landed and the operation can be terminated (S140).

And if the analysis unit (120) analyzes the abnormal operation data and predicts or determines (S135) that the abnormal electronic equipment does not cause an abnormality in the flight of the aircraft (10), the flight of the aircraft (10) can be maintained and the operation data generated from the electronic equipment (A, B1,...Bn) can be continuously collected (S120) and a series of processes can be performed.

On the other hand, if there is no abnormal operation data among the collected operation data (S131), a series of processes are performed by collecting operation data (S120) until the aircraft (10) completes its mission (S132), and when the mission is completed (S132), the aircraft (10) can be landed and the operation can be terminated (S140).

In this way, the operational data, abnormal operational data, abnormal electronic equipment, maintenance data, landing orders, etc. collected from the analysis unit (120) can be visualized on the output unit (140) installed in the aircraft (10). Accordingly, the captain of the aircraft (10) can check the various pieces of information visualized on the output unit (140) and maintain the flight or attempt a landing.

When the mission is completed (S132), the aircraft (10) can be landed and the operation can be terminated (S140).

Thereafter, the operator can connect the verification unit (130) to the analysis unit (120) installed in the aircraft (10) using a transmission unit, for example, an Ethernet cable. At this time, if the verification unit (130) is provided as a mobile terminal, the verification unit (130) can be moved inside the aircraft (10) and the analysis unit (120) and the verification unit (130) can be connected to each other using the transmission unit. Alternatively, if the verification unit (130) is provided in a control center or maintenance facility on the ground, the analysis unit (120) and the verification unit (130) located outside the aircraft (10) can be connected to each other using the transmission unit.

When the analysis unit (120) and the verification unit (130) are connected to each other, various data stored in the first storage (122) of the analysis unit (120) can be transmitted to the verification unit (130). At this time, the various data can include operation data generated from electronic devices, abnormal operation data and data on abnormal electronic devices searched or selected by the first explorer (123), maintenance data on abnormal electronic devices, landing information, etc.

Referring to FIG. 5, when data is transmitted from the analysis unit (120) to the verification unit (130), the verification unit (130) can receive the data (S151) and store the data in the second storage (132). Then, the second explorer (133) of the verification unit (130) can search for abnormal operation data (S152) using the reference operation data stored in the second storage (132) and the operation data transmitted from the analysis unit (120), and search for abnormal electronic equipment that generated the searched abnormal operation data (S153). In addition, the second explorer (133) can be linked to the abnormal electronic equipment and search for the abnormal electronic equipment that caused the abnormal electronic equipment to generate the abnormal operation data.

In this way, when abnormal electronic equipment is detected, verification data for repairing the abnormal electronic equipment can be generated (S154). The verification data is data for verifying whether there is an abnormality, i.e. an error, in the maintenance data generated by the analysis unit (120), and may be identical to or different from the maintenance data.

Additionally, if an abnormal electronic device is discovered that is associated with an abnormal electronic device and causes the abnormal electronic device to generate abnormal operating data, additional verification data for servicing the abnormal electronic device can be generated.

When verification data is generated, the verifier (135) can compare the verification data with the maintenance data stored in the second storage (132) (S155).

As a result of the comparison, if the verification data is identical to the maintenance data, the maintenance data can be determined as the final maintenance data for servicing the abnormal electronic equipment, or the abnormal electronic equipment and the electronic equipment causing the abnormality, and stored in the second storage device (132) (S156).

On the other hand, if the verification data is different from the maintenance data, it is determined that there is an error in the maintenance data, and the verification data can be determined as the final maintenance data for servicing the abnormal electronic equipment and stored in the second storage device (132) (S157).

Once the final maintenance data is determined in this way, the final maintenance data can be stored in the second storage device (132). In addition, the final maintenance data can be visualized on the output unit (140) so that the captain or worker can check it.

And, the worker can check the final maintenance data visualized in the output section (140) and perform maintenance on the abnormal electronic equipment. For example, the worker can inspect the abnormal electronic equipment and replace or repair the parts of the abnormal electronic equipment according to the inspection results. In addition, maintenance can also be performed on the abnormal electronic equipment causing the abnormality that is linked to the abnormal electronic equipment.

According to an embodiment of the present invention, maintenance data of electronic equipment that may affect the flight of an aircraft can be generated, and the generated maintenance data can be verified. Accordingly, the accuracy of the maintenance data can be improved, and the maintenance efficiency of abnormal electronic equipment can be increased. In addition, not only abnormal electronic devices, but also abnormal electronic devices linked to abnormal electronic devices can be searched, and maintenance for abnormal electronic devices can be performed, so that the health of the aircraft can be managed more stably.
