Description

Technical Field

[0001] The present invention relates to the field of equipment testing technology, and in particular to a triaxial atmospheric data subsystem testing system and method. Background Technology

[0002] The three-axis atmospheric data subsystem is one of the most important components of an aircraft. It requires a large amount of data to be measured, and its parameters are very important information for the pilot. It also has very high requirements for the accuracy and real-time performance of signal acquisition.

[0003] Before installation, three-axis atmospheric data subsystems often require testing and verification to ensure all system functions are normal and to prevent malfunctions during ground testing due to substandard product performance. Furthermore, in practical applications, the three-axis atmospheric data subsystem also needs to be tested as needed to facilitate aircraft maintenance and troubleshooting, improving the efficiency of field maintenance. However, due to the complexity of the working principle and control laws of the three-axis atmospheric data subsystem, and the large number of interconnected components on the aircraft, aircraft maintenance is extremely challenging. When testing is required for an onboard three-axis atmospheric data subsystem, it is often necessary to return it to the original manufacturer for testing.

[0004] In the process of realizing this invention, the inventors discovered the following defects in the prior art: the equipment used by the original manufacturer to test the triaxial atmospheric data subsystem is usually a non-movable device fixed on the workbench, which has poor testing flexibility and is difficult to meet diverse testing needs. Summary of the Invention

[0005] This invention provides a three-axis atmospheric data subsystem detection system and method, which can realize on-demand detection of the three-axis atmospheric data subsystem and improve the flexibility of the three-axis atmospheric data subsystem detection.

[0006] According to one aspect of the present invention, a three-axis atmospheric data subsystem detection system is provided, comprising a main control module, an interactive display screen, a signal data processing chassis, a data transmission module, and a power conditioning board, wherein: The interactive display screen is communicatively connected to the main control module and is used to receive offline detection commands input by the user and send the offline detection commands to the main control module. The main control module is used to generate control commands according to the offline detection instructions and send the control commands to the signal data processing chassis; The signal data processing chassis is communicatively connected to the main control module and the data transmission module. It is used to generate analog input data according to the control command, and send the analog input data to the data transmission module, which then transmits the analog input data to the triaxial atmospheric data subsystem. The triaxial atmospheric data subsystem is used to acquire and process the analog input data to obtain first offline detection output data; and / or, the signal data processing chassis is used to receive second offline detection output data fed back by the triaxial atmospheric data subsystem through the data transmission module. The main control module is also used to respond to the offline detection command, receive the first offline detection output data fed back by the data transmission module, and / or receive the second offline detection output data fed back by the signal data processing chassis, and detect the first offline detection output data and / or the second offline detection output data, and feed back the detection results to the interactive display screen for display; The power conditioning board is used to supply power to the triaxial atmospheric data subsystem and the triaxial atmospheric data subsystem detection system. The triaxial atmospheric data subsystem is communicatively connected to the test fixture and the atmospheric source. The test fixture is used to provide the triaxial atmospheric data subsystem with a test angle position; the atmospheric source is used to provide the triaxial atmospheric data subsystem with air pressure altitude.

[0007] According to another aspect of the present invention, a method for detecting a three-axis atmospheric data subsystem is provided, characterized in that it is applied to the three-axis atmospheric data subsystem detection system described in the first aspect, the method comprising: Receive offline detection commands input by the user; Generate control commands based on the offline detection instructions; The system generates simulated input data according to the control command, inputs the simulated input data to the triaxial atmospheric data subsystem, and obtains the first offline detection output data obtained by the triaxial atmospheric data subsystem from the acquisition and processing of the simulated input data; and / or receives the second offline detection output data fed back by the triaxial atmospheric data subsystem. In response to the offline detection command, the first offline detection output data and / or the second offline detection output data are detected.

[0008] This invention utilizes a main control module, an interactive display screen, a signal data processing chassis, a data transmission module, and a power conditioning board to construct a three-axis atmospheric data subsystem testing system. During testing, the three-axis atmospheric data subsystem is communicatively connected to the test fixture and the atmospheric source. The test fixture provides the three-axis atmospheric data subsystem with the test angle position, and the atmospheric source provides the atmospheric pressure altitude. Correspondingly, the interactive display screen in the three-axis atmospheric data subsystem testing system can receive offline testing commands input by the user and send these commands to the main control module. The main control module can generate control commands based on the offline testing commands and send them to the signal data processing chassis. The signal data processing chassis can generate analog input data based on the control commands and send the analog input data to the data transmission module. The data transmission module then sends the analog input data to the three-axis atmospheric data subsystem, which can then collect and process the analog input data to obtain the first offline testing output data. And / or, the signal data processing chassis can also receive the second offline testing output data fed back by the three-axis atmospheric data subsystem through the data transmission module. Correspondingly, the main control module can respond to offline detection commands, receive first offline detection output data from the data transmission module, and / or receive second offline detection output data from the signal data processing chassis, and perform detection on the first and / or second offline detection output data, ultimately feeding back the detection results to the interactive display screen for display. The above technical solution can solve the problems of poor detection flexibility and inability to meet on-demand detection requirements in existing three-axis atmospheric data subsystem detection methods, enabling on-demand detection of the three-axis atmospheric data subsystem and improving the flexibility of three-axis atmospheric data subsystem detection.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. 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 comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0014] Example 1

[0015] Figure 1 This is a schematic diagram of a triaxial atmospheric data subsystem detection system provided in Embodiment 1 of the present invention, as shown below. Figure 1 As shown, the structure of the three-axis atmospheric data subsystem detection system includes: a main control module 110, an interactive display screen 120, a signal data processing chassis 130, a data transmission module 140, and a power conditioning board 150, wherein: The interactive display screen 120 is communicatively connected to the main control module 110 and is used to receive offline detection commands input by the user and send the offline detection commands to the main control module 110.

[0016] The interactive display screen 120 can be any type of display screen capable of interacting with the user, such as, but not limited to, a touch screen. Optionally, the interactive display screen 120 can be an industrial-grade sunlight-readable screen for easy outdoor operation. The offline testing command can be user-triggered and used to perform offline testing on the three-axis atmospheric data subsystem. Offline testing means testing the three-axis atmospheric data subsystem after it has been removed from the aircraft. The three-axis atmospheric data subsystem can be a system composed of the main test objects within the three-axis atmospheric data system. For example, taking the three-axis atmospheric data subsystem equipped on the 19 series helicopter as an example, the test objects included in the three-axis atmospheric data subsystem can be the atmospheric data computer XAS-5A, the atmospheric data computer XSC-31, and the velocity vector sensor GSS-1A, etc.

[0017] In this embodiment of the invention, the user can input various detection commands for the three-axis atmospheric data subsystem via the interactive display screen 120. Optionally, the types of detection commands for the three-axis atmospheric data subsystem may include, but are not limited to, button commands, voice commands, and various trigger commands suitable for the touchscreen (such as clicks or swipes).

[0018] In this embodiment of the invention, the three-axis atmospheric data subsystem detection system can provide users with an offline detection method, allowing users to trigger offline detection commands via the interactive display screen 120. After detecting that the user has triggered an offline detection command, the interactive display screen 120 sends the command to the main control module 110.

[0019] The main control module 110 is used to generate control commands based on offline detection instructions and send the control commands to the signal data processing chassis 130.

[0020] The main control module 110, as the core component of the three-axis atmospheric data subsystem detection system, can control the signal input and output of the entire three-axis atmospheric data subsystem detection system and realize the coordination and control of various functions. Optionally, the main control module 110 can be an industrial control computer.

[0021] Correspondingly, after receiving the offline detection command, the main control module 110 can parse it and generate the control command corresponding to the offline detection command based on the parsing result, and then send the control command to the signal data processing chassis 130.

[0022] Therefore, the main control module and the touch screen are the core control components of the entire three-axis atmospheric data subsystem testing system. They are used to control and display the signal input and output of the entire three-axis atmospheric data subsystem testing system, realize the coordinated operation and automatic detection of various test functions, and are also responsible for user management, test data storage and test result display.

[0023] The signal data processing chassis 130 is communicatively connected to the main control module 110 and the data transmission module 140. It is used to generate analog input data according to control commands and send the analog input data to the data transmission module 140, so that the analog input data can be sent to the triaxial atmospheric data subsystem 160 through the data transmission module 140. The triaxial atmospheric data subsystem 160 is used to collect and process the analog input data to obtain the first offline detection output data; and / or, the signal data processing chassis 130 is used to receive the second offline detection output data fed back by the triaxial atmospheric data subsystem 160 through the data transmission module 140.

[0024] The signal data processing chassis 130 is responsible for signal conditioning and acquisition, data conversion, and signal switching, and can communicate using a custom bus or a standard bus. The analog input data can be data simulated by the signal data processing chassis 130 according to the detection requirements of the triaxial atmospheric data subsystem. The data transmission module 140 provides data transmission functionality between the signal data processing chassis 130, the triaxial atmospheric data subsystem 160, and the main control module 110. For example, the data transmission module 140 can be an aviation connector. The first offline detection output data can be the data output by the triaxial atmospheric data subsystem 160 after data acquisition and corresponding calculation processing based on the analog input data in an offline detection scenario. The second offline detection output data can be the data actively input to the signal data processing chassis 130 by the triaxial atmospheric data subsystem 160 during the offline detection process. The first and second offline detection output data reflect the working status of the triaxial atmospheric data subsystem 160 in the offline detection scenario.

[0025] In most detection scenarios, the signal data processing chassis 130 can simulate the corresponding input data type according to the detection requirements of the triaxial atmospheric data subsystem, generate simulated input data, and send the simulated input data to the data transmission module 140. That is, in these detection scenarios, the triaxial atmospheric data subsystem 160 passively receives and processes the data to generate the corresponding first offline detection output data. It should be noted that during offline detection, some scenarios require the detection of the second offline detection output data actively generated by the triaxial atmospheric data subsystem 160. When the triaxial atmospheric data subsystem 160 actively generates the second offline detection output data, it can feed it back to the data transmission module 140, which then feeds it back to the signal data processing chassis 130. Further, the signal data processing chassis 130 can process the second offline detection output data and send it to the main control module 110 for detection.

[0026] The data transmission module 140 provides a reliable electrical and mechanical connection for the triaxial atmospheric data subsystem 160 to transmit signals, power, and data. Accordingly, the data transmission module 140 can input received analog input data to the triaxial atmospheric data subsystem 160, and can also input the second offline detection output data fed back from the triaxial atmospheric data subsystem 160 to the signal data processing chassis 130.

[0027] The main control module 110 is also used to respond to the offline detection command, receive the first offline detection output data fed back by the data transmission module 140, and / or receive the second offline detection output data fed back by the signal data processing chassis 130, and detect the first offline detection output data and / or the second offline detection output data, and feed back the detection results to the interactive display screen 120 for display.

[0028] Correspondingly, when the data transmission module 140 inputs the received analog input data to the triaxial atmospheric data subsystem 160, the triaxial atmospheric data subsystem 160 can collect and process the analog input data to obtain the first offline detection output data, and feed the first offline detection output data back to the main control module 110 through the data transmission module 140. And / or, when the triaxial atmospheric data subsystem 160 actively generates the second offline detection output data in response to the control command and sends it to the data transmission module 140, the data transmission module 140 feeds it back to the signal data processing chassis 130 for processing, and the signal data processing chassis 130 sends the processed data to the main control module 110.

[0029] Since the analog input data can simulate the data output by various devices under normal operating conditions, the process of the triaxial atmospheric data subsystem 160 acquiring and processing the analog input data can also effectively simulate the passive data acquisition state of the triaxial atmospheric data subsystem 160 on the machine. Since the second offline detection output data can simulate the data actively output by the triaxial atmospheric data subsystem 160 during interaction with relevant on-machine devices under normal operating conditions, the signal data processing chassis 130, which simulates the devices interacting with the triaxial atmospheric data subsystem 160, can effectively simulate the active data generation state of the triaxial atmospheric data subsystem 160 on the machine. Therefore, the main control module 110 detects the first offline detection output data and / or the second offline detection output data output by the triaxial atmospheric data subsystem 160, such as determining whether the first offline detection output data and / or the second offline detection output data are within the corresponding data range, or determining whether the first offline detection output data and / or the second offline detection output data are the set output values, thereby realizing a comprehensive detection of the engine parameter acquisition function of the triaxial atmospheric data subsystem 160, and feeding back the detection results to the interactive display screen 120 for real-time display.

[0030] In offline testing, the triaxial atmospheric data subsystem testing system can adopt a dual power supply mode selectable between AC 220V 50HZ and DC 28V. The input AC 220V 50HZ is converted into DC voltage by an AC-to-DC module, and this voltage is selected in parallel with the DC 28V input power supply, with the 28V DC input taking priority. The power supply, after being selected by the power conditioning board 150, becomes two outputs: 28V DC and 12V DC, which can power the triaxial atmospheric data subsystem 160 and the entire triaxial atmospheric data subsystem testing system. In offline testing, the triaxial atmospheric data subsystem 160 also needs to communicate with the test fixture 170 and the atmospheric source 180. The test fixture 170 can provide the test angle position of the velocity vector sensor for testing the output accuracy of the velocity vector sensor at different angles, that is, it can provide the test angle position for the triaxial atmospheric data subsystem 160. Atmospheric Source 180 is a portable testing device that can provide a stable dynamic and static pressure testing environment for the triaxial atmospheric data subsystem under both indoor and outdoor working conditions. It has programmable control functions and can be used in conjunction with the automatic testing functions of the triaxial atmospheric data subsystem detection system. Specifically, it can provide atmospheric pressure altitude for the triaxial atmospheric data subsystem 160, including total pressure (Pt) altitude and static pressure (Ps) altitude.

[0031] Optionally, in the offline testing mode, the offline testing commands may include, but are not limited to, partial testing commands and full testing commands. When a user triggers a partial testing command to perform offline testing on the three-axis atmospheric data subsystem 160, the system can test some of the parameter acquisition functions of the three-axis atmospheric data subsystem 160 according to the specific functions to be tested specified in the partial testing command. When a user triggers a full testing command to perform offline testing on the three-axis atmospheric data subsystem 160, the system can test all the parameter acquisition functions of the three-axis atmospheric data subsystem 160 in sequence according to the default function testing order of the full testing commands. Throughout the entire testing process, the user only needs to trigger the corresponding testing commands, and the three-axis atmospheric data subsystem testing system can automatically complete the functional testing process of the three-axis atmospheric data subsystem 160 according to the testing commands triggered by the user.

[0032] In an optional embodiment of the present invention, the interactive display screen 120 is further configured to receive in-situ detection instructions input by the user and send the in-situ detection instructions to the main control module 110; the data transmission module 140 is further configured to receive in-situ detection output data from the triaxial atmospheric data subsystem 160; the main control module 110 is further configured to respond to the in-situ detection instructions, receive the in-situ detection output data fed back by the data transmission module 140, detect the in-situ detection output data, and feed back the detection results to the interactive display screen 120 for display.

[0033] The in-situ detection command can be user-triggered and used to perform in-situ detection on the triaxial atmospheric data subsystem 160. In-situ detection refers to detecting the triaxial atmospheric data subsystem 160 while it is in operation on the aircraft. The in-situ detection output data can be the data collected and processed by the triaxial atmospheric data subsystem 160 during normal on-air operation in the in-situ detection scenario, after which it outputs the data.

[0034] In this embodiment of the invention, the triaxial atmospheric data subsystem detection system can also provide an in-situ detection method for the user, who can trigger an in-situ detection command based on the interactive display screen 120. After the interactive display screen 120 detects that the user has triggered an in-situ detection command, it sends the in-situ detection command to the main control module 110. At this time, when the main control module 110 confirms that the current detection command is an in-situ detection command, it does not need to perform any processing, that is, it does not need to generate a corresponding control command, and can directly wait for the triaxial atmospheric data subsystem 160 to provide feedback on the detection data.

[0035] In the in-situ detection scenario, since the triaxial atmospheric data subsystem 160 is in normal operating mode on the aircraft, there is no need to generate analog input data through the signal data processing chassis 130. The triaxial atmospheric data subsystem 160 can normally collect relevant parameters of the engine in the fuselage as in-situ detection output data for output. Optionally, the in-situ detection output data may include data passively collected and processed by the triaxial atmospheric data subsystem 160, or it may include data actively processed by the triaxial atmospheric data subsystem 160. This embodiment of the invention does not limit the data type and content of the in-situ detection output data. Correspondingly, the in-situ detection output data output by the triaxial atmospheric data subsystem 160 can be directly fed back to the main control module 110 through the data transmission module 140. After receiving the in-situ detection output data, the main control module 110 can directly detect the in-situ detection output data, such as determining whether the in-situ detection output data is within the corresponding data range, or determining whether the in-situ detection output data is the set output value, thereby realizing a comprehensive detection of the engine parameter acquisition function of the three-axis atmospheric data subsystem 160, and feeding back the detection results to the interactive display screen 120 for real-time display.

[0036] In the in-situ detection method, the triaxial atmospheric data subsystem 160 can be directly powered by the machine body, so the power conditioning board 150 can only power the entire triaxial atmospheric data subsystem detection system.

[0037] The triaxial atmospheric data subsystem testing system provided in this embodiment of the invention can be housed in a portable equipment case. The main control module 110, interactive display screen 120, signal data processing chassis 130, data transmission module 140, and power conditioning board 150 can all be installed inside the portable equipment case, making it convenient to carry and highly portable, meeting the needs of testing anytime and anywhere. Optionally, the equipment case can have a two-layer structure design. The upper layer of the equipment case can be the front panel of the triaxial atmospheric data subsystem testing system, in which the interactive display screen 120 for user interaction can be installed. The bottom layer of the equipment case can be the signal data processing chassis. In offline testing scenarios, when the triaxial atmospheric data subsystem 160 needs to be tested, it is only necessary to connect the triaxial atmospheric data subsystem 160 to the triaxial atmospheric data subsystem testing system via the data transmission module 140. The user can then trigger offline testing commands based on the triaxial atmospheric data subsystem testing system to perform real-time functional testing on the triaxial atmospheric data subsystem 160. In the in-situ testing scenario, when it is necessary to test the three-axis atmospheric data subsystem 160, the three-axis atmospheric data subsystem 160 only needs to be connected to the three-axis atmospheric data subsystem testing system through the data transmission module 140. The user can then trigger the in-situ testing command based on the three-axis atmospheric data subsystem testing system to perform functional testing on the three-axis atmospheric data subsystem 160 in real time.

[0038] In a specific example, assuming the triaxial atmospheric data subsystem includes the XAS-5A atmospheric data computer, the XSC-31 atmospheric data computer, and the GSS-1A velocity vector sensor, the key testing items for the XAS-5A atmospheric data computer are: power supply testing, leakage testing, self-test signal checks, output parameter checks, acceleration / deceleration testing, and fault signal checks. The signals that need to be tested for the XAS-5A atmospheric data computer may include, but are not limited to, DC input power, AC input power, temperature analog input signal, angle analog input signal, field pressure setpoint analog input signal, analog output signal, ARINC429 transmit signal, ARINC429 receive signal, static pressure Ps signal, and total pressure Pt. For the XSC-31 atmospheric data computer, the key testing items are: power consumption testing, power output testing, self-test testing, airtightness testing, and output accuracy testing. The XSC-31 atmospheric data computer needs to test signals including, but not limited to, DC input power, AC input power, temperature analog input signal, angle analog input signal, analog output signal, AC output signal, ARINC429 transmit signal, ARINC429 receive signal, static pressure Ps signal, and total pressure Pt. For the GSS-1A velocity vector sensor, the focus can be on testing power consumption, pitot tube azimuth, temperature sensor, and heating circuit. The signals tested by the GSS-1A velocity vector sensor include, but are not limited to, DC input power, AC input power, angle analog output signal, and temperature sensor output signal.

[0039] Therefore, the triaxial atmospheric data subsystem inspection system provided in this embodiment of the invention not only supports offline inspection of the triaxial atmospheric data subsystem but also in-situ inspection, meeting the multi-directional inspection needs of the triaxial atmospheric data subsystem. Furthermore, the offline inspection method also meets the need for inspection anytime and anywhere. In other words, the aforementioned triaxial atmospheric data subsystem inspection system can achieve on-demand inspection of the triaxial atmospheric data subsystem, improving the flexibility of triaxial atmospheric data subsystem inspection.

[0040] This invention utilizes a main control module, an interactive display screen, a signal data processing chassis, a data transmission module, and a power conditioning board to construct a three-axis atmospheric data subsystem testing system. During testing, the three-axis atmospheric data subsystem is communicatively connected to the test fixture and the atmospheric source. The test fixture provides the three-axis atmospheric data subsystem with the test angle position, and the atmospheric source provides the atmospheric pressure altitude. Correspondingly, the interactive display screen in the three-axis atmospheric data subsystem testing system can receive offline testing commands input by the user and send these commands to the main control module. The main control module can generate control commands based on the offline testing commands and send them to the signal data processing chassis. The signal data processing chassis can generate analog input data based on the control commands and send the analog input data to the data transmission module. The data transmission module then sends the analog input data to the three-axis atmospheric data subsystem, which can then collect and process the analog input data to obtain the first offline testing output data. And / or, the signal data processing chassis can also receive the second offline testing output data fed back by the three-axis atmospheric data subsystem through the data transmission module. Correspondingly, the main control module can respond to offline detection commands, receive first offline detection output data from the data transmission module, and / or receive second offline detection output data from the signal data processing chassis, and perform detection on the first and / or second offline detection output data, ultimately feeding back the detection results to the interactive display screen for display. The above technical solution can solve the problems of poor detection flexibility and inability to meet on-demand detection requirements in existing three-axis atmospheric data subsystem detection methods, enabling on-demand detection of the three-axis atmospheric data subsystem and improving the flexibility of three-axis atmospheric data subsystem detection.

[0041] Example 2

[0042] Figure 2 This is a schematic diagram of a three-axis atmospheric data subsystem detection system provided in Embodiment 2 of the present invention. This embodiment is a specific embodiment based on the above embodiment. In this embodiment, the specific composition structure of the signal data processing chassis and various optional specific functional implementation methods of each analog test module within the signal data processing chassis are given. Correspondingly, as... Figure 1 and Figure 2 As shown, the signal data processing chassis 130 may include a communication control module 131, a bus backplane 132, a backplane power supply 133, and multiple analog test modules 134: wherein: The communication control module 131 is connected to the main control module 110 and is used to receive control commands output by the main control module 110, convert the control commands into target bus control commands, and send the target bus control commands to the bus backplane 132.

[0043] The bus backplane 132 is communicatively connected to the communication control module 131 and to each simulation test module 134, and is used to forward the target bus control commands to the simulation test module 134.

[0044] The communication control module 131, acting as the data forwarding and transmission module of the signal data processing chassis 130, establishes a communication connection between the signal data processing chassis 130 and the main control module 110, and is responsible for converting control commands initiated by the main control module 110. The target bus control command can be a control command suitable for transmission via a target type bus protocol, obtained by the communication control module 131 converting the control command. It is understood that the target bus control command and the control commands directly issued by the main control module 110 have the same function: to generate corresponding analog input data for the control simulation test module or to receive the second offline detection output data fed back by the triaxial atmospheric data subsystem. The bus backplane 132 can use a target type bus protocol for data transmission. Optionally, the target type bus protocol can be any type of bus protocol, or even a custom bus protocol, as long as it can be used to transmit target bus control commands. This embodiment of the invention does not limit the type of bus protocol used for the target type bus protocol.

[0045] Optionally, the main control module 110 can communicate with the communication control module 131 of the signal data processing chassis 130 via a serial bus of a certain type, such as an RS232 serial bus. The communication control module 131 can convert the control commands initiated by the main control module 110 via the serial bus into target bus control commands suitable for internal communication, and send them to other simulation test modules 134 through the bus backplane 132, thereby achieving the purpose of controlling and measuring the entire triaxial atmospheric data subsystem detection system.

[0046] For example, the communication control module 131 can convert the serial port command format control commands issued by the main control module 110 into RS485 bus control commands applicable to the bus backplane 132 as target bus control commands, and send them to other analog test modules 134 to complete signal control, switching, and test measurement functions. Simultaneously, the communication control module 131 can also convert the test data fed back from the analog test modules 134 into serial port commands and feed them back to the main control module 110 for measurement display. The bus backplane 132 is mainly used for signal conversion, transferring the conditioned output control signals of the communication control module 131 to the backplane power supply 133 and each analog test module 134 via 12 rows of standard European 48-pin sockets, with point-to-point connections between each row of sockets.

[0047] The simulation test module 134 is communicatively connected to the data transmission module 140. It is used to generate simulation input data according to the target bus control command, and input the simulation input data to the triaxial atmospheric data subsystem 160 through the data transmission module 140, or receive the second offline detection output data fed back by the triaxial atmospheric data subsystem 160 through the data transmission module 140.

[0048] In this embodiment of the invention, the target bus control command can be a control command for a specific analog test module 134. Correspondingly, the communication control module 131 can send the target bus control command to the corresponding analog test module 134 via the bus backplane 132. After receiving the target bus control command, the analog test module 134 can respond to the command by generating corresponding analog input data and inputting the generated analog input data to the triaxial atmospheric data subsystem 160 via the data transmission module 140. During offline testing, some testing scenarios require testing the second offline testing output data actively generated by the triaxial atmospheric data subsystem 160. When the triaxial atmospheric data subsystem 160 actively generates the second offline testing output data, it can feed the actively generated second offline testing output data back to the data transmission module 140, which then feeds the second offline testing output data back to the corresponding analog test module 134 within the signal data processing chassis 130. Further, the analog test module 134 processes the second offline testing output data and sends it to the main control module 110 for testing. Optionally, the target bus control command can be used to control one of the simulation test modules 134 to generate corresponding simulation input data, or to control one of the simulation test modules 134 to receive data fed back from the triaxial atmospheric data subsystem, so as to test a certain function of the triaxial atmospheric data subsystem 160.

[0049] The backplane power supply 133 can supply power to the bus backplane 132, the data transmission module 140, and each analog test module 134. For example, the backplane power supply 133 can convert the input 12V DC power into 5V, 15V, and -15V DC power supplies for use by other functional modules on the bus backplane 132. It can also convert the input 12V DC power, filter it, and then introduce it into the bus backplane 132 for use by other functional modules. In other words, the backplane power supply 133 can control the output of four DC power supplies—28V, 15V, -15V, and 5V—for use by each functional module during testing, and can read the current consumption of the four output power supplies.

[0050] In an optional embodiment of the present invention, the control command may include a data acquisition control command, and the simulation test module may include a data acquisition board. The data acquisition board may be used to: in response to the data acquisition control command, acquire a first set number of output data fed back by the triaxial atmospheric data subsystem through the data transmission module; wherein the first set number of output data includes air pressure data, position data, and temperature data; feed back the first set number of output data to the main control module through the bus backplane and the communication control module; the main control module is also used to detect the first set number of output data and feed back the detection result to the interactive display screen for display.

[0051] The data acquisition control command can be used to control the data acquisition board to acquire data output from the triaxial atmospheric data subsystem. The data acquisition board can be used to simulate data acquisition equipment. The first set quantity of output data can be the data type actively output by the triaxial atmospheric data subsystem. That is, the first set quantity of output data belongs to a second type of offline detection output data. Optionally, the first set quantity can be set according to test requirements, such as 4, etc. The embodiments of the present invention do not limit the specific value of the first set quantity.

[0052] Figure 3 This is a schematic diagram of another triaxial atmospheric data subsystem detection system provided in Embodiment 2 of the present invention. In a specific example, Figure 3 The three-axis atmospheric data subsystems equipped on the 19 series helicopters are used as the testing objects, such as... Figure 3As shown, the data transmission module can utilize an aviation connector. One of the simulation test modules within the signal data processing chassis can include a data acquisition board. Correspondingly, when the main control module initiates a data acquisition control command, the data acquisition board receives and responds to the command, simulating a data acquisition device to receive a first predetermined number of output data, such as air pressure data, position data, and temperature data, fed back from the triaxial atmospheric data subsystem via the data transmission module. This first predetermined number of output data is then fed back to the main control module via the bus backplane and communication control module. Upon receiving the first predetermined number of output data, the main control module can output it to the interactive display screen for display. Simultaneously, it can detect the first predetermined number of output data, determining whether the actual displayed values ​​meet the required specifications, and feed the detection results back to the interactive display screen. For example, the data acquisition board can acquire and measure two analog signals, one AC signal, and one resistance signal output by the triaxial atmospheric data subsystem through the data transmission module. The two analog signals can reflect the air pressure data output by the triaxial atmospheric data subsystem, the one AC signal can reflect the positioning information (i.e., position) data output by the triaxial atmospheric data subsystem, and the one resistance signal can reflect the temperature data output by the triaxial atmospheric data subsystem.

[0053] In an optional embodiment of the present invention, the control command may include a bus simulation control command, and the simulation test module may include a bus simulator and a relay matrix board. The bus simulator may be used to: simulate and output a second set number of simulated bus signals in response to the bus simulation control command; and send the second set number of simulated bus signals to the relay matrix board; wherein the simulated bus signals include simulated transmit bus signals and simulated receive bus signals; the relay matrix board may be used to: switch the second set number of simulated bus signals to a third set number of simulated bus signals, and perform bus signal transmission and reception interaction with the three-axis atmospheric data subsystem based on the third set number of simulated bus signals; the main control module is also used to detect the third set number of simulated bus signals and feed back the detection results to the interactive display screen for display.

[0054] The bus simulation control command can be used to control the bus simulator and relay matrix board to jointly realize the simulation function of bus transmission and reception. The bus simulator can be used to simulate bus signals. The relay matrix board can be used to test the output of some types of resources, and also to control the connection and disconnection of measurement signals with the three-axis atmospheric data subsystem. Optionally, the relay matrix board can be a 4x8 double-pole double-throw channel relay matrix module. The second set quantity can be set according to the test requirements, such as 2, etc., and the specific value of the second set quantity is not limited in this embodiment. The simulated bus signal can be the bus signal simulated by the bus simulator and relay matrix board, and can include two types: simulated bus transmission signal and simulated bus reception signal. The simulated bus transmission signal is the simulated bus transmission signal, and the simulated bus reception signal is the simulated bus reception signal. The third set quantity can be set according to the test requirements, such as 4, etc., and the specific value of the third set quantity is not limited in this embodiment. In the simulated bus signal, the simulated bus transmission signal belongs to a first type of offline detection output data, and the simulated bus reception signal belongs to a second type of offline detection output data.

[0055] In a specific example, continuing with the above... Figure 3 The example shown illustrates that two of the simulation test modules within the signal data processing chassis may include a bus simulator and a relay matrix board. Accordingly, when the main control module initiates a bus simulation control command, the bus simulator can receive the command and, in response, work with the relay matrix to simulate bus data transmission and reception, thereby simulating the bus function of an avionics system. For instance, the bus simulator can, in response to the bus simulation control command, simulate two channels of ARINC429 bus signals, including one simulated bus transmit signal and one simulated bus receive signal. These one and one simulated bus transmit signals are sent to the relay matrix, which then switches them to two transmit and two receive ARINC429 signals, i.e., two simulated bus transmit signals and two simulated bus receive signals.

[0056] Correspondingly, the two analog bus transmit signals can be used as analog input data to the triaxial atmospheric data subsystem. After acquiring and processing the analog bus transmit signals, the triaxial atmospheric data subsystem obtains the acquired data and outputs it to the aviation connector, which then forwards it to the main control module. Upon receiving the acquired data, the main control module outputs it to the interactive display screen for display. Simultaneously, it can detect the acquired data, determining whether the actual displayed value meets the specifications, and feeds the detection result back to the interactive display screen. The two analog bus receive signals can be the output data from the triaxial atmospheric data subsystem via the data transmission module. These signals can be fed back to the main control module via the bus backplane and communication control module. Upon receiving these signals, the main control module outputs them to the interactive display screen and can also detect them, determining whether the actual displayed value meets the specifications, and feeding the detection result back to the interactive display screen.

[0057] In an optional embodiment of the present invention, the control command may include a temperature and pressure simulation control command, and the simulation test module may include a temperature and pressure simulator. The temperature and pressure simulator may be used to: simulate temperature and pressure simulation signals as temperature and pressure simulation input data in response to the temperature and pressure simulation control command; the temperature and pressure simulation signals may be used to control the working state of the triaxial atmospheric data subsystem; the triaxial atmospheric data subsystem may be used to collect and process the temperature and pressure simulation input data to obtain temperature and pressure correlated acquisition data; the main control module may also be used to receive the temperature and pressure correlated acquisition data fed back by the data transmission module, detect the temperature and pressure correlated acquisition data, and feed back the detection results to the interactive display screen for display.

[0058] The temperature and pressure simulation control command can be used to control the temperature and pressure simulator to generate corresponding temperature and pressure simulation input data. The temperature and pressure simulator can be a simulator used to generate temperature and pressure simulation input data. The temperature and pressure simulation input data is the data used to simulate temperature and pressure. The temperature and pressure correlated acquisition data can be the data obtained after the three-axis atmospheric data subsystem acquires and processes the temperature and pressure simulation input data, and can be used as the acquisition and processing result of the three-axis atmospheric data subsystem for temperature and pressure. In other words, the temperature and pressure correlated acquisition data belongs to a type of first offline detection output data.

[0059] In a specific example, continuing with the above... Figure 3 The example shown illustrates that one of the simulation test modules within the signal data processing chassis may include a temperature and pressure simulator. Correspondingly, when the main control module initiates a temperature and pressure simulation control command, the temperature and pressure simulator receives the command and, in response, simulates temperature and pressure signals as temperature and pressure simulation input data. For instance, the temperature and pressure simulator can simulate one temperature signal and one pressure signal for the three-axis atmospheric data subsystem to control its operating state. Correspondingly, after the three-axis atmospheric data subsystem acquires and processes the temperature and pressure simulation input data, it obtains temperature and pressure correlated acquisition data and outputs it to the aviation connector, which further forwards it to the main control module. Upon receiving the temperature and pressure correlated acquisition data, the main control module can output it to an interactive display screen to show the actual temperature and pressure values. Simultaneously, it can detect the temperature and pressure correlated acquisition data, determining whether the actual displayed values ​​meet the required specifications, and then feed the detection results back to the interactive display screen.

[0060] In an optional embodiment of the present invention, the control command may include an attitude simulation control command, and the simulation test module includes a vector sensor simulator. The vector sensor simulator can be used to: simulate the azimuth angle of the total airflow of the whole machine as attitude simulation input data in response to the attitude simulation control command; the three-axis atmospheric data subsystem can be used to collect and process the attitude simulation input data to obtain attitude calculation data; the main control module can also be used to receive the attitude calculation data fed back by the data transmission module, detect the attitude calculation data, and feed back the detection results to the interactive display screen for display.

[0061] The attitude simulation control command can be used to control the vector sensor simulator to generate corresponding attitude simulation input data. The vector sensor simulator can be a simulator used to generate attitude simulation input data. Attitude simulation input data is data used to simulate attitude information. Attitude solution data can be data obtained after the three-axis atmospheric data subsystem collects and processes the attitude simulation input data; it can be used as the processing result of the three-axis atmospheric data subsystem solving the attitude output from the vector sensor simulator. In other words, attitude solution data belongs to a type of first offline detection output data.

[0062] In a specific example, continuing with the above... Figure 3The example shown illustrates that one of the simulation test modules within the signal data processing chassis may include a vector sensor simulator. Correspondingly, when the main control module initiates an attitude simulation control command, the vector sensor simulator can receive the command and, in response, simulate the azimuth angle of the overall airflow of the entire aircraft as the attitude simulation input data. For instance, the vector sensor simulator can output two attitude calculation signal output channels from the three-axis atmospheric data subsystem to simulate the azimuth angle of the overall airflow of the entire aircraft, thereby providing the aircraft's flight attitude. Correspondingly, after the three-axis atmospheric data subsystem acquires and processes the attitude simulation input data, it can obtain attitude calculation data and output it to the aviation connector, which further forwards it to the main control module. Upon receiving the attitude calculation data, the main control module can output the data to the interactive display screen to show the actual display value of the corresponding azimuth angle attitude. Simultaneously, it can detect the attitude calculation data, i.e., determine whether the actual display value meets the requirements, and feed the detection result back to the interactive display screen.

[0063] In an optional embodiment of the present invention, the control command may include an atmospheric engine simulation control command, and the simulation test module may include an atmospheric engine simulator; wherein, the atmospheric engine simulator may be used to: in response to the atmospheric engine simulation control command, simulate receiving azimuth data from the velocity vector sensor received by the three-axis atmospheric data subsystem, and feed back the azimuth data of the velocity vector sensor to the main control module through the bus backplane and the communication control module; the main control module may also be used to detect the azimuth data of the velocity vector sensor and feed back the detection result to the interactive display screen for display.

[0064] The atmospheric engine simulation control command can be used to control the atmospheric engine simulator to receive azimuth data from the velocity vector sensor received by the three-axis atmospheric data subsystem. The atmospheric engine simulator can be a simulator used to receive azimuth data from the velocity vector sensor received by the three-axis atmospheric data subsystem. The azimuth data from the velocity vector sensor is a type of second offline detection output data.

[0065] In a specific example, continuing with the above... Figure 3The example shown illustrates that one of the simulation test modules within the signal data processing chassis may include an atmospheric engine simulator. Accordingly, when the main control module initiates an atmospheric engine simulation control command, the atmospheric engine simulator can receive the command and, in response, simulate receiving azimuth data from the velocity vector sensor received by the three-axis atmospheric data subsystem. For instance, the atmospheric engine simulator can provide two solution signal receiving channels to simulate the azimuth angle of the velocity vector sensor received by the three-axis atmospheric data subsystem. Correspondingly, the atmospheric engine simulator can feed back the received azimuth angle data from the velocity vector sensor to the main control module via the bus backplane and communication control module. After receiving the azimuth angle data from the velocity vector sensor, the main control module can output it to the interactive display screen for display. Simultaneously, it can detect the azimuth angle data of the velocity vector sensor, i.e., determine whether the actual displayed value of the azimuth angle data meets the specification requirements, and feed back the detection result to the interactive display screen.

[0066] In an optional embodiment of the present invention, the control command may include an AC power supply simulation control command, and the simulation test module may include an AC power supply simulation board. The AC power supply simulation board may be used to: simulate an atmospheric data computer using AC power as AC power supply simulation input data in response to the AC power supply simulation control command; the triaxial atmospheric data subsystem may be used to collect and process the AC power supply simulation input data to obtain excitation signal associated acquisition data; the main control module may also be used to receive the excitation signal associated acquisition data fed back by the data transmission module, detect the excitation signal associated acquisition data, and feed back the detection results to the interactive display screen for display.

[0067] The AC power simulation control command can be used to control the AC power simulation board to generate corresponding AC power simulation input data. The AC power simulation board can be a simulation board used to generate the AC power simulation data. The AC power simulation input data is the data simulated by the AC power supply. The excitation signal associated acquisition data can be the data obtained after the three-axis atmospheric data subsystem acquires and processes the AC power simulation input data. In other words, the AC power simulation input data belongs to a type of first offline detection output data.

[0068] In a specific example, continuing with the above... Figure 3The example shown illustrates that one of the simulation test modules within the signal data processing chassis may include an AC power simulation board. Correspondingly, when the main control module initiates an AC power simulation control command, the AC power simulation board can receive the command and, in response, the atmospheric data computer uses AC power as the AC power simulation input data. Optionally, the AC power simulation board may include a 115V AC power board and a 36V AC power board. The 115V AC power board can simulate providing one channel of 115V 400Hz AC power for the three-axis atmospheric data subsystem, used for the excitation signal of the angle calculation in the three-axis atmospheric data subsystem. The 36V AC power board can provide one channel of 36V 400Hz AC power for the vector sensor, used for the excitation input of the velocity vector sensor. Correspondingly, after the triaxial atmospheric data subsystem acquires and processes the analog input data from the AC power supply, it can obtain excitation signal correlation data, such as the excitation signal for angle calculation by the triaxial atmospheric data subsystem and the excitation input from the velocity vector sensor. This excitation signal correlation data is then output to the aviation connector, which further forwards it to the main control module. Upon receiving the excitation signal correlation data, the main control module can output it to the interactive display screen to show the actual display value. Simultaneously, it can perform detection on the excitation signal correlation data, determining whether the actual display value meets the required specifications, and then feed the detection result back to the interactive display screen.

[0069] The three-axis atmospheric data subsystem testing system of this invention mainly consists of hardware functional modules such as a main control module, an interactive display screen, a power conditioning board, a bus backplane, a communication control module, a backplane power supply, a data acquisition board, a bus simulator, a relay matrix board, a temperature and pressure simulator, a vector sensor simulator, an atmospheric engine simulator, an AC power supply simulation board, and aviation connectors. When the three-axis atmospheric data subsystem testing system can be housed in a portable equipment box, the main control module, interactive display screen, switches, test ports, indicator lights, and aviation connectors can be mounted on the front panel of the upper layer of the equipment box. The hardware functional modules such as the bus backplane, communication control module, backplane power supply, data acquisition board, bus simulator, relay matrix board, temperature and pressure simulator, vector sensor simulator, atmospheric engine simulator, AC power supply simulation board, and aviation connectors can be mounted on the lower chassis.

[0070] This invention utilizes a main control module, an interactive display screen, a signal data processing chassis, a data transmission module, and a power conditioning board to construct a three-axis atmospheric data subsystem testing system. During testing, the three-axis atmospheric data subsystem is communicatively connected to the test fixture and the atmospheric source. The test fixture provides the three-axis atmospheric data subsystem with the test angle position, and the atmospheric source provides the atmospheric pressure altitude. Correspondingly, the interactive display screen in the three-axis atmospheric data subsystem testing system can receive offline testing commands input by the user and send these commands to the main control module. The main control module can generate control commands based on the offline testing commands and send them to the signal data processing chassis. The signal data processing chassis can generate analog input data based on the control commands and send the analog input data to the data transmission module. The data transmission module then sends the analog input data to the three-axis atmospheric data subsystem, which can then collect and process the analog input data to obtain the first offline testing output data. And / or, the signal data processing chassis can also receive the second offline testing output data fed back by the three-axis atmospheric data subsystem through the data transmission module. Correspondingly, the main control module can respond to offline detection commands, receive first offline detection output data from the data transmission module, and / or receive second offline detection output data from the signal data processing chassis, and perform detection on the first and / or second offline detection output data, ultimately feeding back the detection results to the interactive display screen for display. The above technical solution can solve the problems of poor detection flexibility and inability to meet on-demand detection requirements in existing three-axis atmospheric data subsystem detection methods, enabling on-demand detection of the three-axis atmospheric data subsystem and improving the flexibility of three-axis atmospheric data subsystem detection.

[0071] Example 3

[0072] Figure 4 This is a flowchart illustrating a method for detecting a triaxial atmospheric data subsystem according to Embodiment 3 of the present invention. This embodiment is applicable to detecting triaxial atmospheric data subsystems using the triaxial atmospheric data subsystem detection system described in any of the above embodiments. Correspondingly, as... Figure 4 As shown, the method includes the following operations: S310: Receives offline detection commands input by the user.

[0073] In this embodiment of the invention, a user can trigger an offline detection command based on the interactive display screen. After detecting that the user has triggered the offline detection command, the interactive display screen sends the offline detection command to the main control module.

[0074] S320. Generate control commands based on the offline detection instructions.

[0075] Correspondingly, after receiving the offline detection command, the main control module can parse it and generate the corresponding control command based on the parsing result, thereby sending the control command to the signal data processing chassis.

[0076] S130. Generate simulated input data according to the control command, and input the simulated input data to the three-axis atmospheric data subsystem to obtain the first offline detection output data obtained by the three-axis atmospheric data subsystem from the acquisition and processing of the simulated input data; and / or, receive the second offline detection output data fed back by the three-axis atmospheric data subsystem.

[0077] In most detection scenarios, the signal data processing chassis can simulate the corresponding input data type according to the detection requirements of the three-axis atmospheric data subsystem, generate simulated input data, and send the simulated input data to the data transmission module. That is, in these detection scenarios, the three-axis atmospheric data subsystem passively receives and processes data, thereby generating the corresponding first offline detection output data. It should be noted that during offline detection, some scenarios require the detection of a second offline detection output data actively generated by the three-axis atmospheric data subsystem. When the three-axis atmospheric data subsystem actively generates the second offline detection output data, it can feed it back to the data transmission module, which then feeds it back to the signal data processing chassis. Further, the signal data processing chassis can process the second offline detection output data and send it to the main control module for detection.

[0078] Correspondingly, after the data transmission module receives the analog input data and inputs it into the triaxial atmospheric data subsystem, the triaxial atmospheric data subsystem can collect and process the analog input data to obtain the first offline detection output data, and then feed the first offline detection output data back to the main control module through the data transmission module. Alternatively, when the triaxial atmospheric data subsystem actively generates the second offline detection output data and sends it to the data transmission module, the data transmission module feeds it back to the signal data processing chassis for processing, and the signal data processing chassis sends the processed data back to the main control module. Since the analog input data can simulate the data output by various devices under normal operating conditions, the process of the triaxial atmospheric data subsystem collecting and processing the analog input data can also effectively simulate the working state of the triaxial atmospheric data subsystem passively collecting data on the machine. Since the second offline detection output data can simulate the data actively output by the triaxial atmospheric data subsystem during interaction with relevant devices on the machine under normal operating conditions, simulating the devices interacting with the triaxial atmospheric data subsystem through the signal data processing chassis can effectively simulate the working state of the triaxial atmospheric data subsystem actively generating interactive data on the machine.

[0079] S140. In response to the offline detection instruction, detect the first offline detection output data and / or the second offline detection output data.

[0080] The main control module detects the first offline detection output data and / or the second offline detection output data output by the three-axis atmospheric data subsystem. For example, it determines whether the first offline detection output data and / or the second offline detection output data are within the corresponding data range, or whether the first offline detection output data and / or the second offline detection output data are the set output values. This enables a comprehensive detection of the engine parameter acquisition function of the three-axis atmospheric data subsystem, and the detection results are fed back to the interactive display screen for real-time display.
