Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, system, electronic device, and readable storage medium for monitoring the security performance of an airborne communication terminal. Background Technology

[0002] Airborne terminals, such as critical airborne communication equipment, are essential components for high-security information transmission and critical position tracking in aircraft. Airborne communication terminals include communication equipment deployed inside the aircraft cabin and antennas deployed outside the fuselage. The intermediate frequency (IF) cables connecting the antennas and communication equipment are also mostly deployed outside the fuselage. These IF cables are exposed to the natural environment, making them susceptible to aging due to light, rain, and other environmental factors, and also highly vulnerable to human damage. If the IF cables are damaged or their performance degrades, the communication equipment cannot effectively communicate with the antenna, jeopardizing the safe flight of the aircraft.

[0003] Therefore, how to monitor the safety performance of airborne communication terminals and detect in a timely manner the performance degradation or damage of the radio frequency cable is a technical problem that needs to be solved by technicians in this field. Summary of the Invention

[0004] This application provides a method, apparatus, system, electronic device, and readable storage medium for monitoring the security performance of airborne communication terminals, which can monitor the security performance of airborne communication terminals and detect in a timely manner the performance degradation or damage of the radio frequency cable.

[0005] To address the aforementioned technical problems, the embodiments of the present invention provide the following technical solutions:

[0006] One embodiment of the present invention provides a method for monitoring the security performance of an airborne communication terminal, comprising:

[0007] Multiple biological detectors are pre-installed around the intermediate radio frequency cable; each biological detector is used to detect whether there are biological organisms in the target area including the intermediate radio frequency cable.

[0008] When operating in safety performance monitoring mode, it determines whether there are biological signals;

[0009] If the biological signal is received, the detection cycle is determined according to the detection parameters corresponding to the target biological detector that collects the biological signal;

[0010] According to the detection cycle, a detection signal is sent via a communication transmitter;

[0011] The degree of damage to the radio frequency cable is determined based on the antenna's response to the detection signal.

[0012] Optionally, after determining the degree of damage to the radio frequency cable based on the antenna's response to the detection signal, the method further includes:

[0013] Warnings are issued to the driver's terminal and the ground system based on the extent of the damage.

[0014] Optionally, the step of issuing warnings to the driver's terminal and the ground system respectively based on the damage level information includes:

[0015] By analyzing the damage level information, it can be determined whether the radio frequency cable has experienced performance degradation or has been damaged.

[0016] If the radio frequency cable is in a state of performance degradation, the damage level information is transmitted to the cockpit via the avionics interface and displayed to the pilot, along with a Level 1 alarm; the damage level information is also transmitted to the ground system via the short message transceiver module, and a Level 1 alarm is displayed.

[0017] If the radio frequency cable is damaged, the damage level information is transmitted to the cockpit via the avionics interface and displayed to the pilot, and a level 2 alarm is displayed; the damage level information is also transmitted to the ground system via the aircraft air-to-ground communication equipment, and a level 2 alarm is displayed; the level 2 alarm is higher than the level 1 alarm.

[0018] Optionally, when operating in security performance monitoring mode, determining the presence of biological signals includes:

[0025] To determine whether biological signals are present.

[0026] Optionally, determining the degree of damage to the radio frequency cable based on the antenna's response to the detection signal includes:

[0027] Determine whether a response signal is received from the antenna based on the detection signal, which lasts for the detection period;

[0028] If no response signal is received from the antenna according to the detection signal for the duration of the detection period, then the radio frequency cable has been damaged.

[0029] When a response signal is received from the antenna that lasts for the detection period based on the detection signal, the cable attenuation value is calculated based on the response signal and the initial standard response signal;

[0030] If the cable attenuation value is greater than or equal to the preset maximum attenuation value, the mid-frequency cable is damaged; if the cable attenuation value is less than the preset maximum attenuation value, the mid-frequency cable is degraded.

[0035] The damage detection module is used to determine the degree of damage to the radio frequency cable based on the antenna's response to the detection signal.

[0040] When the communication device executes the computer program stored in the memory, it implements the steps of the airborne communication terminal security performance monitoring method as described in any of the preceding claims.

[0041] The advantage of the technical solution provided in this application is that a biological detector deployed near the RF cable can detect whether a biological entity is approaching the RF cable, send a signal to the antenna and collect the antenna's feedback signal.

[0050] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] The terms "first," "second," "third," "fourth," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may include steps or units not listed.

[0052] After introducing the technical solutions of the embodiments of the present invention, the various non-limiting embodiments of this application will be described in detail below.

[0053] First see Figure 1 , Figure 1 This is a flowchart illustrating a method for monitoring the security performance of an airborne communication terminal according to an embodiment of the present invention. The embodiment of the present invention may include the following:

[0054] S101: Multiple biological detectors are pre-installed around the mid-frequency cable.

[0055] In this embodiment, the intermediate frequency (IF) cable is a communication cable connecting the airborne communication terminal and the antenna. The bio-detector is used to detect the presence of living organisms within its monitoring range. This monitoring range includes the target area containing the IF cable; that is, each bio-detector is used to detect the presence of living organisms within the target area containing the IF cable. The number of bio-detectors can be determined based on the monitoring area of ​​the bio-detectors, the wiring of the IF cable, and the length of the IF cable. Those skilled in the art can make flexible selections based on actual conditions. The bio-detector can employ any existing sensor capable of detecting living organisms such as humans or birds, such as a human body sensor using the microwave Doppler principle; this application does not impose any limitations on this. The bio-detector is deployed near the IF cable where living organisms can access it, and the deployment location can be flexibly selected based on actual conditions.

[0056] S102: When operating in safety performance monitoring mode, determine whether there is a biological signal. If yes, proceed to S103. If no, continue monitoring.

[0057] The safety performance monitoring mode refers to the operating mode activated when the aircraft deploying the airborne communication terminal is on the ground. In other words, when the airborne communication terminal is in safety performance monitoring mode, it needs to monitor whether the radio frequency cable connecting the airborne communication terminal and the antenna has been damaged by living organisms. The airborne communication terminal can monitor each organism detector in real time or at regular intervals. If the organism detector detects the presence of a living organism within its monitoring range, it sends a monitoring information signal indicating the presence of a living organism to the airborne communication terminal.

[0058] S103: If a biological signal is received, the detection cycle is determined according to the detection parameters corresponding to the target biological detector that collects the biological signal.

[0059] For ease of description, the biodetector that feeds back biosignals to the airborne communication terminal is referred to as the target biodetector. If a biosignal is received from the biodetector, the target biodetector is located, and the detection cycle is determined based on its location information. The detection cycle refers to the transmission time of the detection signal and the response signal. Detection parameters can be the detection distance or the biodetector's installation location information.

[0060] S104: According to the detection cycle, send the detection signal through the communication transmitter.

[0061] In this embodiment, upon detecting a biological signal, the airborne communication terminal's transmitter will send a signal to the antenna. This signal, referred to as the detection signal, is transmitted to the antenna via an intermediate frequency (IF) cable. If the IF cable is damaged or disconnected, the antenna will not receive the detection signal. If the IF cable is damaged but still operational, the antenna will receive the detection signal.

[0062] S105: Determine the degree of damage to the radio frequency cable based on the antenna's response to the detection signal.

[0063] After the airborne communication terminal sends a detection signal to the antenna in the previous step, the antenna will respond to the received detection signal, and the airborne communication terminal will receive this response signal. If the airborne communication terminal cannot receive the response signal, it indicates that the intermediate frequency (RF) cable has been damaged to the point of inoperability (e.g., disconnected). The airborne communication terminal receives the response signal and compares its signal strength with the response signal received when the RF cable is functioning normally. By comparing the signal strength, the extent of damage to the RF cable can be determined, allowing for timely maintenance of the RF cable.

[0064] In the technical solution provided in the embodiments of the present invention, a biological detector deployed near the RF cable can detect whether a biological entity is approaching the RF cable, sends a signal to the antenna and collects the antenna's feedback signal. The presence or absence and strength of the feedback signal can determine whether the RF cable is damaged or whether its performance is aging. This allows for timely detection of RF cable performance degradation or damage, enabling effective monitoring of the safety performance of the airborne communication terminal and helping to ensure the safe and stable flight of the aircraft.

[0065] It should be noted that there is no strict order of execution for the steps in this application. As long as they conform to a logical order, these steps can be executed simultaneously or in a certain preset order. Figure 1 This is just an illustrative example and does not mean that this is the only possible execution order.

[0066] In the above embodiments, there is no limitation on how to execute step S102. This embodiment provides an optional implementation method for when to enter the security performance monitoring mode, which may include:

[0067] As an optional implementation, wheel-mounted signals are acquired; if an invalid wheel-mounted signal is detected, a safety performance monitoring mode is entered; and it is determined whether biological signals are present.

[0068] As another optional implementation method parallel to the above embodiments, the positioning output information is obtained, and the positioning output rate is determined based on the positioning output information; if the positioning output rate is greater than or equal to a preset rate threshold, the safety performance monitoring mode is entered; and it is determined whether there is a biological signal.

[0069] In this embodiment, the wheel-borne signal is an indication of whether the aircraft is on the ground, and it is a signal transmitted from the avionics system to the BeiDou device. To obtain the wheel-borne signal, the BeiDou device needs to acquire the wheel-borne signal from the aircraft. When the BeiDou device is not connected to the aircraft's avionics, the alternative judgment method for the "wheel-borne signal" is: to judge by the positioning output information of the BeiDou device. When the positioning output rate of the BeiDou device is less than Y meters per second, the "wheel-borne signal" is valid.

[0070] This embodiment provides multiple ways to enter the security performance monitoring mode, which is suitable for various application scenarios and is more practical.

[0071] In the above embodiments, there is no limitation on how to perform step S105. This embodiment provides an optional implementation for determining the degree of damage information of the radio frequency cable based on the antenna's response information to the detection signal, which may include:

[0072] Determine whether a response signal is received from the antenna based on the continuous detection period sent by the detection signal;

[0073] If no response signal is received from the antenna according to the continuous detection cycle, the RF cable has been damaged.

[0074] When a response signal is received from the antenna during a continuous detection period based on the detection signal, the cable attenuation value is calculated based on the response signal and the initial standard response signal.

[0075] If the cable attenuation value is greater than or equal to the preset maximum attenuation value, the mid-frequency cable is damaged; if the cable attenuation value is less than the preset maximum attenuation value, the mid-frequency cable is degraded.

[0076] In this embodiment, the preset maximum attenuation can be flexibly selected according to the actual situation, which does not affect the implementation of this application.

[0077] Furthermore, in order to perform timely maintenance on the mid-frequency cable, based on the above embodiments, after determining the degree of damage to the mid-frequency cable according to the antenna's response to the detection signal, the following may also be included:

[0078] Warnings are issued to both the driver's terminal and the ground system based on the extent of the damage.

[0079] Specifically, by analyzing the damage level information, it is determined whether the RF cable has experienced performance degradation or is already damaged. If the RF cable has experienced performance degradation, the damage level information is transmitted to the cockpit via the avionics interface and displayed to the pilot, along with a Level 1 alarm. The damage level information is also transmitted to the ground system via the short message transceiver module, and a Level 1 alarm is displayed. If the RF cable is already damaged, the damage level information is transmitted to the cockpit via the avionics interface and displayed to the pilot, along with a Level 2 alarm. The damage level information is also transmitted to the ground system via the aircraft's air-to-ground communication equipment, and a Level 2 alarm is displayed. The Level 2 alarm level is higher than the Level 1 alarm level.

[0080] This invention also provides a corresponding device for the airborne communication terminal security performance monitoring method, further enhancing the practicality of the method. The device can be described from both a functional module perspective and a hardware perspective. The airborne communication terminal security performance monitoring device provided in this invention is described below, and the airborne communication terminal security performance monitoring device described below can be referred to in conjunction with the airborne communication terminal security performance monitoring method described above.

[0085] The damage detection module 204 is used to determine the degree of damage to the radio frequency cable based on the antenna's response to the detection signal.

[0086] Optionally, in some embodiments of this example, the device may further include an alarm module for issuing warnings to the driver terminal and the ground system respectively based on the degree of damage information.

[0087] As an optional implementation of the above embodiments, the alarm module can be used to determine whether the intermediate radio frequency cable is degraded or damaged by parsing the damage level information; if the intermediate radio frequency cable is degraded, the damage level information is transmitted to the cockpit via the avionics interface and displayed to the pilot, and a level one alarm is displayed; the damage level information is transmitted to the ground system via the short message transceiver module and a level one alarm is displayed; if the intermediate radio frequency cable is damaged, the damage level information is transmitted to the cockpit via the avionics interface and displayed to the pilot, and a level two alarm is displayed; the damage level information is transmitted to the ground system via the aircraft air-to-ground communication equipment and a level two alarm is displayed; the level two alarm is higher than the level one alarm.

[0100] It is understood that if the airborne communication terminal security performance monitoring method in the above embodiments is implemented as a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, or all or part of the technical solution, can be embodied in the form of a software product.

[0101] Based on this, embodiments of the present invention also provide a readable storage medium storing a computer program, wherein when the computer program is executed by a processor, the steps of the airborne communication terminal security performance monitoring method of any of the above embodiments are as follows.

[0102] This invention also provides an airborne communication terminal security performance monitoring system; please refer to [link to relevant documentation]. Figure 4 It may include the following:

[0103] The airborne communication terminal safety performance monitoring system may include an airborne communication terminal 41 and multiple biological detectors 42. The airborne communication terminal 41 may include communication equipment, an antenna, and a mid-frequency radio frequency cable; each biological detector is deployed around the mid-frequency radio frequency cable according to a preset deployment rule and feeds back the collected biological signals to the communication equipment. When the communication equipment executes a computer program stored in its memory, it implements the steps of any of the above embodiments of the airborne communication terminal safety performance monitoring method.

[0104] The preset deployment rules can be determined based on the monitoring area of ​​the biodetector, the wiring of the RF cable, the length of the RF cable, and the area of ​​the RF cable accessible to the organism. For example, the biodetector is placed next to the RF cable where the organism can access it. If H meters of the cable are exposed in the accessible area, a biodetector can be placed every X meters. The total number of biodetectors is H / X rounded down, such as 10 / 2 = 5. Biodetectors can be implemented in various ways, such as using microwave Doppler human body sensors, like the YTMW8631 or YT-EWS. Two biodetectors can be placed at each location: biodetector A can detect biosignals from 0 to X meters; biodetector B can detect biosignals from 0 to X / L meters, where L is a positive number greater than 1.

[0105] To enable those skilled in the art to more clearly understand the technical solution of this application, this application combines... Figure 5 An illustrative example is given, which may include the following:

[0106] In this embodiment, the airborne BeiDou system may include an airborne communication terminal, an antenna, and a mid-frequency radio frequency (RF) cable connecting the two. The airborne communication terminal may include an RF cable tamper detection unit, a cable attenuation information transmission module, a BeiDou short message transceiver module, an avionics interface, and an A429 interface. The airborne communication terminal connects to the cockpit via the avionics interface and to the aircraft's air-to-ground communication equipment via the A429 interface. The RF cable tamper detection unit includes a signal AD acquisition and signal processing module, which is integrated into the airborne communication terminal. Multiple human body detectors are deployed near the RF cable, which is accessible to humans. Each human body detector is connected to the RF cable tamper detection unit to provide feedback on detected human body signals.

[0107] When an invalid wheel-mounted signal is detected, the RF cable tamper detection unit is activated. Human body sensor A and human body sensor B are two human body detectors classified according to detection distance. Human body sensor A can detect people at a distance of X meters, while human body sensor B can only detect people at a distance of X / L meters. The following uses human body sensor A and human body sensor B as an example to illustrate the entire technical solution:

[0108] When someone approaches the RF cable, the human body sensor A detects the human body signal and transmits it to the RF cable tamper detection unit. The RF cable tamper detection unit then initiates terminal transceiver loopback detection, with a detection cycle of T.

[0109] The transceiver loopback detection process is as follows: The terminal's transmitter sends a detection signal lasting T / 2 seconds to the BeiDou antenna. Based on the detection signal, the BeiDou antenna sends a response signal lasting T / 2 seconds back to the terminal. If the signal received by the airborne equipment is close to the signal strength received during initial installation, it indicates that the RF cable is not damaged. If the airborne equipment does not receive a signal or the received signal is weaker than the signal strength received during initial installation, it indicates that the RF cable is damaged, and the cable attenuation value is output. For example, if the normal received signal is X dB and the received signal is Y dB when the signal is weakened, then the cable attenuation value is X-Y dB.

[0110] When the human body sensor B detects a human body signal, the RF cable human-caused damage detection unit initiates terminal transceiver loopback detection. The detection cycle of the terminal transceiver loopback detection is T / L.

[0111] The transceiver loopback detection process is as follows: The terminal's transmitter sends a continuous T / 2L detection signal to the BeiDou antenna. Based on the detection signal, the BeiDou antenna sends a continuous T / 2L response signal back to the terminal. If the signal received by the airborne equipment is close to the signal strength received during initial installation, it indicates that the RF cable is not damaged. If the airborne equipment does not receive a signal or the received signal is weaker than the signal strength received during initial installation, it indicates that the RF cable is damaged, and the cable attenuation value is issued. For example, if the normal received signal is XdB and the received signal is YdB when the signal is weakened, then the cable attenuation value is X-YdB.

[0112] When receiving cable attenuation value information, the operation process of the radio frequency cable human-caused damage detection unit is as follows:

[0113] (a) Case 1: When the terminal transceiver loopback detection finds that the cable attenuation value is not less than Z1 (Z1 attenuation is the maximum attenuation value at which the Beidou short message module cannot work) dB: The RF cable human-caused damage detection unit simultaneously sends the cable attenuation value information to the cable attenuation value information sending module: The cable attenuation value information sending module transmits the cable attenuation value information to the cockpit through the avionics interface and displays it to the pilot, and displays a yellow alarm; The cable attenuation value information sending module transmits the cable attenuation value information to the ground system through the Beidou short message transceiver module and displays a yellow alarm.

[0114] (b) Scenario 2: When the terminal transceiver loopback detection finds that the cable attenuation value is greater than Z1 (Z1 attenuation is the maximum attenuation value at which the Beidou short message module cannot work) dB: The RF cable human-caused damage detection unit simultaneously sends the cable attenuation value information to the cable attenuation value information sending module: The cable attenuation value information sending module transmits the cable attenuation value information to the cockpit through the avionics interface and displays a red alarm; The cable attenuation value information sending module connects the cable attenuation value information to the aircraft air-to-ground communication equipment (such as satellite communication, ATG, etc.) through the A429 interface, and the air-to-ground communication equipment transmits the cable attenuation value information to the ground system and displays a red alarm.

The specific implementation process can be referred to the relevant descriptions in the above method embodiments, which will not be repeated here.

[0116] As can be seen from the above, the embodiments of the present invention can monitor the safety performance of airborne communication terminals and detect in a timely manner the performance degradation or damage of the radio frequency cable.
