[0049] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. The described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0050] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0052] Aircraft situational awareness (SA) refers to the flight control system's ability to perceive the aircraft's current state and its surroundings. Specifically, aircraft situational awareness can help pilots understand the current aircraft's operating conditions by collecting and displaying information about the aircraft's state and surroundings, thereby helping to improve the safety of aircraft operations.

[0053] In the related technologies, situational awareness is generally achieved based on various sensors and auxiliary systems. These sensors are of various types, relatively costly, and have weak capabilities for complex situational awareness and low practicality.

[0054] In view of this, an aircraft situation awareness method based on an intelligent coating system is provided in an embodiment of the present application, and a standard signal matrix is ​​established according to the deployment position points of the signal transmitters and the signal receivers of each group; wherein the standard signal matrix is ​​used to record the signal transmission link between the signal transmitters and the signal receivers of each group; when the aircraft is in operation, the first signal received by each signal receiver is obtained; the first signal is compared with the standard signal, and an abnormal signal is determined from the first signal; wherein the standard signal is a signal received by the signal receiver without interference; according to the abnormal signal, an abnormal area is determined in the standard signal matrix; according to the abnormal area, the situation awareness result corresponding to the aircraft is determined. This method can make full use of the physical and chemical properties of the magnetic fluid itself, and realize various situation awareness applications while maintaining low cost, low complexity, low maintenance difficulty and without significantly modifying the body. It is highly practical and can be beneficial to ensuring flight safety.

[0055] Before introducing the aircraft situation awareness method provided in the embodiment of the present application, first, an intelligent painting system provided in the embodiment of the present application is introduced and explained.

[0056] In the embodiment of the present application, the intelligent coating system includes an electromagnetically controlled sensor array and a composite paint surface laid on the surface of the aircraft. Figure 1 , Figure 1 A schematic diagram of a composite paint surface of an intelligent coating system provided in an embodiment of the present application is shown. For the composite paint surface, it includes an insulating primer layer, a magnetic fluid coating and a protective paint layer sequentially laid on the skin of the aircraft surface. The insulating primer layer is laid directly on the skin of the aircraft surface, the magnetic fluid coating is laid on the insulating primer layer, and the protective paint layer is laid on the magnetic fluid coating. In some embodiments, the protective paint layer can adopt a high-transmittance protective paint layer. The high-transmittance protective paint layer generally refers to a coating material applied to the surface to provide protection and increase transparency. This coating is widely used in various fields, such as automobiles, electronic products, furniture, artwork protection, etc., has a good protective effect, and has good transparency and is easy to clean.

[0057] In the embodiment of the present application, the electromagnetic control sensor array includes a plurality of sets of matching signal transmitters and signal receivers. Figure 2 , Figure 2 A schematic diagram of an electromagnetic control sensor array provided in an embodiment of the present application is shown. In the electromagnetic control sensor array, each group of matching signal transmitters and signal receivers can be arranged in a horizontally and vertically staggered manner, and both the signal transmitters and signal receivers can be connected to the magnetic fluid coating.

[0058] In the embodiment of the present application, the overall operating principle of the intelligent coating system is as follows:

[0059] In the electromagnetic control sensor array, the matching signal transmitter and signal receiver are connected to the magnetic fluid coating. The signal generator transmits signals to the corresponding signal receiver in a directional manner. When the signal emitted by the signal transmitter or the external signal passes through the magnetic fluid material, under ideal conditions, the signal will be received and recognized by the corresponding signal receiver. In addition, when a strong signal passes through the magnetic fluid material, it will also cause the magnetic fluid material to fluctuate greatly. This method can achieve artificial control of the magnetic fluid material.

[0060] Please refer to Figure 3 , Figure 3 is a flow chart of an aircraft situation awareness method based on an intelligent painting system provided in an embodiment of the present application, with reference to Figure 3 The aircraft situation awareness method based on the intelligent painting system includes but is not limited to:

[0061] Step 310: Establish a standard signal matrix according to the deployment locations of the signal transmitters and signal receivers of each group; wherein the standard signal matrix is ​​used to record the signal transmission links between the signal transmitters and signal receivers of each group;

[0062] Step 320: When the aircraft is in operation, obtain the first signal received by each of the signal receivers;

[0063] Step 330: compare the first signal with a standard signal, and determine an abnormal signal from the first signal; wherein the standard signal is a signal received by the signal transmitter without interference;

[0064] Step 340: determining an abnormal area in the standard signal matrix according to the abnormal signal;

[0065] Step 350: Determine the situation awareness result corresponding to the aircraft according to the abnormal area.

[0066] In an embodiment of the present application, a method for aircraft situational awareness based on an intelligent painting system is provided. Situational awareness is achieved based on the intelligent painting system provided above. The method can make full use of the physical and chemical properties of the magnetic fluid itself, and realize various situational awareness applications while maintaining low cost, low complexity, low maintenance difficulty and without major modifications to the aircraft body. The method is highly practical and can be beneficial to ensuring flight safety.

[0067] Specifically, in the embodiment of the present application, a standard signal matrix can be established according to the deployment locations of each set of matching signal transmitters and signal receivers. The standard signal matrix can be used to record the signal transmission links between each set of matching signal transmitters and signal receivers. For example, please refer to Figure 2 , Figure 2 The signal transmission links between each set of matching signal transmitters and signal receivers can form a standard signal matrix.

[0068] In an embodiment of the present application, when the aircraft is in operation, the signal received by each signal receiver can be obtained and recorded as the first signal. In an embodiment of the present application, for each signal receiver, the first signal received by them can be compared with the standard signal. Here, the standard signal refers to the signal received by the signal receiver without interference. For example, in an embodiment of the present application, the signal transmitter can be started when the aircraft is in a non-electromagnetic environment interference, and then the signal received by the signal receiver can be recorded as the standard signal.

[0069] It is understandable that in the embodiment of the present application, each signal receiver can correspond to a standard signal. Under normal circumstances, that is, if there is no abnormality in the external environment of the aircraft, the first signal will not be interfered with. At this time, the first signal will be consistent with the standard signal; on the contrary, if there is an abnormality in the external environment of the aircraft, such as a change in electromagnetic information in the external space, it will interfere with the first signal. In this case, the electromagnetic information in the space will pass through the protective layer on the surface of the paint and affect the magnetic fluid coating under the protective layer. The first signal will change and differ from the standard signal. In the embodiment of the present application, each first signal can be compared with the standard signal, and the first signal that is different from the corresponding standard signal can be determined as an abnormal signal.

[0070] In the embodiment of the present application, the abnormal area can be determined from the standard signal matrix established previously according to the abnormal signal. It can be understood that the abnormal signal is the interference signal superimposed on the transmission signal sent by the signal generator and received by the signal receiver. Combined with the deployment position points of each signal receiver that receives the abnormal signal, the abnormal area can be comprehensively screened out.

[0071] Specifically, in some embodiments, determining an abnormal area in the standard signal matrix according to the abnormal signal includes:

[0072] Determine a signal transmission link corresponding to a signal transmitter that receives the abnormal signal as an abnormal signal link;

[0073] The area cross-covered by each of the abnormal signal links is determined as an abnormal area.

[0074] In the embodiment of the present application, when determining the abnormal area, the signal transmission link corresponding to the signal receiver that receives the abnormal signal can be determined as the abnormal signal link. Figure 4 , Figure 4 A schematic diagram of the principle of determining an abnormal area provided in an embodiment of the present application is shown. In the embodiment of the present application, after the abnormal signal links are determined, the area cross-covered by these abnormal signal links can be determined as the abnormal area. According to the characteristics of the determined abnormal area, the situation awareness result corresponding to the aircraft can be determined.

[0075] Generally speaking, there are two main types of situations where an aircraft encounters a special electromagnetic environment when operating at high altitudes. One is meteorological reasons, such as the aircraft's external environment may experience extreme weather conditions such as thunderstorms; the other may be that the aircraft is interfered with by artificial electromagnetic information, such as the aircraft may be illuminated by relevant radars. In the embodiment of the present application, the above two situations can be distinguished by analyzing the abnormal area, and a targeted processing flow can be given.

[0076] Specifically, in some embodiments, determining the situation awareness result corresponding to the aircraft according to the abnormal area includes:

[0077] If the size of the abnormal area is greater than or equal to a preset area threshold, determining that the situation awareness result corresponding to the aircraft is an abnormal atmospheric environment;

[0078] The area threshold is obtained by multiplying the body surface area of ​​the aircraft by a predetermined ratio threshold.

[0079] In the embodiment of the present application, if the abnormal signal is caused by extreme weather conditions such as thunderstorms in the external environment of the aircraft, then the abnormal area will cover most of the aircraft body. Therefore, in the embodiment of the present application, an area threshold can be set in advance. When an abnormal area appears, the size of the abnormal area can be detected and compared with the preset area threshold. If it is found that the size of the abnormal area is greater than or equal to the preset area threshold, it means that extreme weather conditions are likely to be encountered at present. At this time, the situation awareness result corresponding to the aircraft can be regarded as an abnormal atmospheric environment. Relatively speaking, if it is found that the size of the abnormal area is less than the preset area threshold, it means that extreme weather conditions are likely not encountered at present, and other analysis and processing can be performed.

[0080] It should be noted that, in the embodiments of the present application, the size of the area threshold can be flexibly set according to the actual situation, and in some embodiments, it can also be set based on the size of the aircraft itself. For example, in the embodiments of the present application, a ratio threshold can be set, and the area threshold is obtained by multiplying the surface area of ​​the aircraft body and the predetermined ratio threshold. The size of the ratio threshold can also be set according to actual needs, for example, it can be set to 80%, and the present application does not limit this.

[0081] In some embodiments, the method further comprises:

[0082] The atmospheric environment information corresponding to the abnormal area is retrieved from a pre-established database, and the atmospheric environment information is displayed on a pilot display panel of the aircraft.

[0083] In the embodiment of the present application, when it is determined that the situational awareness result corresponding to the current aircraft is an abnormal atmospheric environment, the signal collected when the atmospheric environment is abnormal can be retrieved from the database and compared with the current abnormal area. If the abnormal area collected under a certain atmospheric environment information is found to be consistent with the current one, the atmospheric environment information can be presented to the driver display panel. In this way, it is convenient for the pilot of the aircraft to quickly understand the atmospheric environment outside the aircraft, facilitate targeted operations, improve the aircraft's response speed to abnormal environments, and thus improve the safety of aircraft operations.

[0084] Specifically, in some embodiments, determining the situation awareness result corresponding to the aircraft according to the abnormal area includes:

[0085] If the shape of the abnormal area is a regular shape, and the abnormal area is located at a partial body position of the aircraft or in a single direction, it is determined that the situation awareness result corresponding to the aircraft is radar illumination.

[0086] In the embodiment of the present application, for the case of radar irradiation, since the beam of radar irradiation itself is a relatively regular shape, the shape of the abnormal area formed on the aircraft is generally also a regular shape. Moreover, unlike the situation of abnormal atmospheric environment, radar irradiation is often irradiated in one direction and can only cover part of the aircraft's body position. Therefore, in the embodiment of the present application, the abnormal area is analyzed. If it is found that its shape is a regular shape, and the abnormal area is located in part of the aircraft's body position or in a single direction, it can be determined that the situation awareness result corresponding to the aircraft is radar irradiation. Similarly, in the embodiment of the present application, abnormal signals related to artificial electromagnetic information can also be retrieved from the database for comparison, and the corresponding situation information can be screened out and reported on the driver's display panel. This application will not go into details.

[0087] In some embodiments, the method further comprises:

[0088] generating a countermeasure signal according to the first signal;

[0089] The counter signal is transmitted through the signal transmitter to offset the signal irradiated by the radar at the magnetic fluid coating.

[0090] In the embodiment of the present application, when the above method is applied to a military aircraft, when the information obtained after detection and comparison is that the aircraft is being illuminated by a hostile radar, the onboard computer can analyze the first signal, generate a corresponding counter signal, and then transmit the counter signal through the signal transmitter to cancel the signal on the magnetic fluid controlled layer, thereby performing active radar stealth of the aircraft. In this way, the practicality of aircraft situational awareness can be improved.

[0091] The embodiment of the present application also provides an aircraft situation awareness device based on an intelligent painting system, the device comprising:

[0092] An establishing unit, used to establish a standard signal matrix according to the deployment position points of each group of the signal transmitters and the signal receivers; wherein the standard signal matrix is ​​used to record the signal transmission links between each group of the signal transmitters and the signal receivers;

[0093] an acquisition unit, configured to acquire the first signal received by each of the signal receivers when the aircraft is in operation;

[0094] a comparing unit, configured to compare the first signal with a standard signal, and determine an abnormal signal from the first signal; wherein the standard signal is a signal received by the signal receiver without interference;

[0095] A first processing unit, configured to determine an abnormal area in the standard signal matrix according to the abnormal signal;

[0096] The second processing unit is used to determine the situation awareness result corresponding to the aircraft according to the abnormal area.
