Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a schematic diagram of an avionics system including an air traffic control (air traffic control, hereinafter abbreviated ATZ) transponder, a weather radar, an integrated monitoring system (Integrated SurveillanceSystem, hereinafter abbreviated ISS), an on-board switch, an on-board display, and other on-board electronics, etc. The on-board exchange is also referred to as an on-board avionics network exchange. Communication between the ISS and the on-board switch is via ARINC664 bus. When the airborne component is integrated into the flight simulator, as no actual weather radar and ATC transponder exist, the airborne component does not have normal weather data and traffic data input, and then the airborne component is caused to have relevant alarm information output, so that a pilot observes unexpected and wrong alarm information during normal flight training, the simulated flight state is inconsistent with the real machine state, and the simulation flight state does not meet the simulator configuration management and control requirements; and the aircraft carrier can not output normal meteorological data and traffic data, so that the flight simulator can not simulate the flight scene of the relevant training subjects.
Aiming at the problem that the configuration state of the simulator does not meet the flight training requirement due to the fact that the relevant warning information is output by the airborne component, the warning information in the output data of the airborne component is eliminated, so that the avionic system and a flight trainer can look like that the airborne component works normally, and the normal simulated flight of the flight simulator is supported. Referring to fig. 2, the present application discloses a simulator monitoring system, which may include: a vehicle 100 and an excitation device 200;
the vehicle mount 100 is configured to: outputting bus data, wherein the bus data at least comprises data to be replaced, and the data to be replaced is transmitted through a virtual link;
the ISS in the avionics system is communicated with the weather radar, the ATZ transponder and the like, and can receive weather data sent by the weather radar, traffic data sent by the ATZ transponder and the like. The weather data can be understood as conventional weather parameter data, and the traffic data can refer to information such as how many airplanes are in the air, and azimuth, speed and altitude of each airplane.
The data to be replaced refers to data that the vehicle 100 needs to provide by other vehicles 100 (weather radar or ATZ transponder). In this embodiment, since there is no actual weather radar and ATC transponder during the experiment, the aircraft carrier 100 of the flight simulator has no normal data input to be replaced, and thus, there is no normal data to be replaced in the output neutral line data of the aircraft carrier 100.
The virtual link refers to a link provided to the vehicle 100 to output the data to be replaced to the outside, and for example, the virtual link may be VL (virtual link), that is, the data to be replaced is output through the virtual link VL.
The excitation device 200 is communicatively connected to the vehicle 100 by wire or wirelessly, and the excitation device 200 is configured to: and receiving the bus data output by the carrier 100, filtering the bus data based on a virtual link to obtain data to be replaced contained in the bus data, deleting and replacing the data to be replaced with simulation data, and taking the bus data containing the simulation data as the bus data to be output.
In the technical solution disclosed in the embodiments of the present application, in order to facilitate the excitation device 200 to better identify the data to be replaced, the identifier of the virtual link may be stored in advance in the excitation device 200, so after the excitation device 200 obtains the bus data (ARINC 664 data) output by the carrier 100, the virtual link may be obtained by filtering the bus data based on the identifier of the virtual link, so that the data transmitted by the first virtual link is deleted. Taking the data to be replaced as meteorological data as an example, the excitation device 200 analyzes ICD data of bus data externally transmitted by the airborne component 100 through the identification of a pre-stored virtual link, determines that four virtual links, namely 33406, 33414, 33391 and 33374, are used for transmitting the meteorological data, and other virtual links in the midline data are used for interaction logic, setting a mode and the like; thus, after obtaining the bus data output by the carrier 100, the data transmitted by the four virtual links 33406, 33414, 33391 and 33374 can be directly determined and deleted as the data to be replaced.
Wherein the excitation device 200 may obtain the simulation data from the simulation device 300 through a simulation port, where the simulation data is used to eliminate alarm information caused by bus data of the vehicle 100.
In the technical solution provided in this embodiment, the simulation device 300 provides simulation data, where the simulation device 300 may generate simulation data through a simulation model or other means, when the simulation model is used to generate the simulation data, specific data verification is pre-agreed between the excitation and the device and the simulation model to perform data interaction, when the excitation device 200 obtains the simulation data, the obtained simulation data may be parsed, and packaged into a specific data packet according to the parsing result, and in order to facilitate identification and replacement, when packaging, the simulation data needs to be packaged according to the ICD data format defined by the carrier 100 and the format of the 664 data packet, so that the packaged simulation data can replace the data to be replaced in the bus data.
The simulation data are generally specific simulation variables, that is, the data types of the data included in the simulation data are consistent with the data types included in the data to be replaced, and the difference is that the data included in the simulation data are different from the specific parameters included in the data to be replaced, the data included in the simulation data are preset parameters which cannot cause alarm information, therefore, after the data to be replaced in the bus data are replaced by the simulation data, device alarm cannot be caused, taking the data to be replaced as weather data as an example, the simulation device 200 can acquire the simulation data through a SIM (subscriber identity module) port, the simulation data are normal weather data which cannot cause alarm information, after the simulation data are acquired, the simulation device 200 can package the simulation data into a data format consistent with the weather data in the bus data based on the data format of the simulation data, combine the simulation data with the bus data, use the simulation data as the weather data in the bus data, and output the new bus data to the switch through the power outlet of the excitation device 200.
In this scheme, the virtual link in the bus data is not deleted, because related data such as mode switching is also included in the message corresponding to a specific UDP port in the virtual link, and deletion and replacement of the virtual link cannot be performed entirely, specific bytes (data to be replaced) corresponding to alarm information need to be found in the virtual link, and related messages need to be replaced, so that the alarm is eliminated.
When the data to be replaced is screened from the data to be replaced, the excitation device 200 performs data screening and filtering on the bus data based on the virtual link, so as to obtain the data to be replaced contained in the bus data. In the technical solution disclosed in this embodiment, when the excitation device 200 performs data screening and filtering on the bus data based on the virtual link, the data format of the data to be replaced or the data identifier of the virtual link may be used.
In the technical solution disclosed in the embodiments of the present application, data screening is performed on the bus data output by the airborne component 100 based on the virtual link, so as to obtain data to be replaced, then the simulation data is adopted to replace the data to be replaced in the bus data, and at this time, the simulation data is included in the bus data.

as shown in fig. 4, in the workflow diagram of the routing module 201, after the routing module 201 obtains bus data from the carrier 100, an action S1 is performed; and filtering and identifying the bus data to obtain a virtual link where the data to be replaced is located, deleting the data to be replaced in the virtual link, and simultaneously maintaining the virtual link after deleting the data to be replaced. Then, the operation S2: and merging the simulation data with the reserved virtual link where the data to be replaced is located, namely supplementing the simulation data into the reserved virtual link to obtain new bus data, and outputting the new bus data to an airborne network A.
In this embodiment, it is considered that the weather data and the traffic data are one of the conventional parameters that cause the warning information, where the traffic data refers to how many aircraft are in the air, and information such as azimuth, speed, altitude, etc. of each aircraft. At this time, the first type of data may include at least one of weather data and traffic data, that is, it may include weather data or traffic data, or may include both weather data and traffic data. At this time, the first type virtual link may be VL (virtuallink), that is, when the data is to be replaced, the first type virtual link is a virtual link including weather data output to the outside for the vehicle 100, and traffic data output to the outside for the vehicle 100. In the scheme, the weather data and the traffic data which can cause the alarm information in the first-class virtual link are replaced by the simulation data, so that the alarm information caused by the weather data and the traffic data is eliminated.
