Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
The method for generating a self-test screen of a compatible radar based on data configuration according to the present invention is described below with reference to fig. 1, fig. 2, fig. 3, fig. 6, and fig. 7.
As shown in fig. 1, an embodiment of the present invention provides a method for generating a self-checking screen of a compatible radar based on data configuration, including:
104, recoding the configuration file to obtain self-inspection image data;
the configuration file comprises any one or any combination of the following:
decoding real-machine radar data, and storing the obtained file in a preset configuration format;
coding and storing the obtained file in a preset configuration format according to a preset radar image;
coding and storing the obtained file in a preset configuration format according to preset color range data; the color range data comprises at least one group of corresponding radar display areas and radar display colors;
coding and storing the obtained file in a preset configuration format according to a preset color matrix or a color array; the color matrix is a matrix for marking the color of the radar display area; the color array is an array for marking the color of the radar display area.
The main execution body of the embodiment is a radar self-checking program, and the radar self-checking program can be a program running on a radar and a program running in a simulation environment.
In an alternative embodiment, the execution subject of steps 102 and 104 is a radar simulation system; specifically, the execution subject of step 102 and step 104 is a simulation unit of the radar simulation system. The radar simulation system is a preset simulation program, and the simulation program comprises a radar self-checking program.
More specifically, the simulation unit reads the configuration file generated by the configuration file generation unit and stored in the self-test screen database, so that step 102 is performed; subsequently, the simulation unit recodes the read configuration file to obtain the self-test image data, so that step 104 is performed.
Further, in the execution process of step 104, the rule of recoding is determined based on the model and parameters of the radar to be simulated by the radar simulation system, and the obtained self-checking image data after recoding, that is, the execution result of step 104, conforms to the communication transmission protocol and the read-write format of the radar to be simulated.
Similarly, for the radar self-test program running on the radar, the execution result of step 104 conforms to the communication transmission protocol and the read-write format of the radar on which the operation is based.
It should be noted that, step 102 may be to read a specified number of configuration files from the self-test screen database randomly, sequentially, reversely or based on a set rule;
generally speaking, at least one configuration file should exist in the self-checking screen database, and in some embodiments, if the specified number of configuration files read in step 102 is N, at least N configuration files should exist in the self-checking screen database.
If the number of configuration files in the self-check screen database cannot meet the reading requirement of step 102, an error will be generated during the execution of step 102, and in some preferred embodiments, an error message (to the radar main panel or the radar simulation system) may be returned.
In a preferred embodiment, the profile includes location coordinates and color of the self-test image; the profile should meet the criteria for the corresponding radar, e.g., for most weather radars, the profile meets the corresponding radar image criteria in the 708 criteria, wherein the 708 criteria refers to ARINC CHARACTERISTIC 708A-3 from Ehrrey, USA under the standard name AIRBORNE WEATHER RADAR WITH FORWARD LOKING WIND SHEAR DETECTION CAPABILITY.
The configuration file should satisfy the standard of the corresponding radar, specifically, the set of position coordinates satisfies the size and resolution of the radar image, and the color RGB value satisfies the RGB value of the standard color of the radar image.
In step 102, the execution of reading this action according to the type of radar to be self-tested may be:
based on the additional decision steps, namely:
determining the type of the radar to be self-checked and reading a configuration file corresponding to the type (in the scheme, the configuration files in the type self-checking picture database can be read by respectively setting the self-checking picture databases aiming at different types, and the configuration files of different types can be set in the same self-checking picture database and read according to the types of the configuration files);
or, the implementation is based on an operating system/program, for example, for a millimeter wave radar self-inspection system/program, the type of the radar to be self-inspected is determined, and the implementation can be realized by directly reading a configuration file corresponding to the millimeter wave radar according to a preset program; in other words, the configuration file corresponding to the type of the radar to be self-tested can be directly read according to a preset program.
In this embodiment, the configuration file format is the same for the same type of radar (e.g., for millimeter wave radar, for weather radar, etc.), but the input sources of the configuration file are different. It can be understood that the data source cannot be effectively judged from the perspective of the configuration file, and therefore, the self-checking method based on the configuration file can have better compatibility and adapt to the same radar of different companies and different models.
The beneficial effect of this embodiment lies in:
data configuration is carried out through the configuration file, so that various data sources (true machine radar data, preset radar images, preset color range data, preset color matrixes or color arrays) can be compatibly converted into self-checking image data, the radar self-checking process is simplified, setting for different types of data sources is not needed, and the beneficial effect of improving the radar self-checking efficiency is achieved; meanwhile, the method and the device have better adaptability and operation uniformity based on the compatibility characteristic, and the learning cost of operators is reduced.
According to the foregoing embodiment, in this embodiment, as shown in fig. 2, the method for generating a self-test screen of a compatible radar based on data configuration further includes:
if the radar is judged to enter the self-checking state, starting a self-checking timer;
and step 108, if the output of the self-checking timer meets the set self-checking picture output condition, operating a display unit externally connected with the radar to read the self-checking image data, drawing to obtain a self-checking image signal and displaying the self-checking image signal.
If the radar is judged to enter the self-checking state, after the step of starting the self-checking timer, the method further comprises the following steps:
and 110, if the output of the self-checking timer meets the set self-checking sound output condition, generating a self-checking voice signal, and operating a sound unit externally connected with a radar to play an alarm voice corresponding to the self-checking voice signal.
It should be noted that the execution sequence of step 108 and step 110 is not fixed, and the execution timings of both are determined based on the self-test image output condition and the self-test sound output condition, i.e. the execution timings of step 108 and step 110 can be adjusted by setting the self-test image output condition and the self-test sound output condition, so as to meet the design purpose.
In a preferred embodiment, the execution subject of step 106 is a simulation unit of the radar simulation system; the execution subject of steps 108 and 110 is also the simulation unit of the radar simulation system, but the execution of the two requires the simulation unit to call the running sound unit or the display unit. At this time, the sound unit in the radar and the display unit in the radar are understood as the sound unit in the artificial radar and the display unit in the artificial radar.
The display unit, the sound unit and the radar are three parallel units, and the three parallel units in the same level are mutually cross-linked. The display unit includes an image playing device; the sound unit comprises a sound playing device; the image playing device and the sound playing device may be two independent hardware or may be an integrated single hardware.
In the real machine, a self-checking picture is generated by a radar unit, is packaged into a standard format and then is sent to a display unit, the radar unit does not relate to the display of a graph, the picture is stored in a data format, and the display unit can perform graph drawing after receiving data and then can display the picture on a screen (image playing equipment).
Similarly, the self-checking alarm voice is also that the radar unit gives out a voice activation instruction and a voice number, and the voice unit identifies the voice activation instruction and the voice number and then plays a corresponding audio file through a loudspeaker (voice playing equipment). The radar unit does not play the voice, but only generates the data required for playing the voice.
In the simulation, if only a single radar function is simulated, the display unit and the sound unit may be integrated in the radar unit, since there is no external cross-linking and sound and visual phenomena are required. However, in consideration of simulation application scenarios (such as flight training), the whole aircraft is provided with the display unit and the sound unit for other modules, so in practical application, the display unit, the sound unit and the simulation radar are still three parallel units.
Further, a display picture generation subunit and an alarm voice generation subunit may be disposed in the radar unit, and are respectively configured to process the configuration file (read, decode, and encode) to generate self-check image data for the display unit to draw and display, and to generate a voice activation instruction and a voice number for the sound unit to select a specific self-check alarm voice to play.
It should be noted that the display screen generating subunit may generate the self-inspection image data by using an encryption code or other set coding formats, and at this time, the display unit needs to finish drawing and displaying after correspondingly decoding the self-inspection image data.
The beneficial effect of this embodiment lies in:
by introducing the timer, the self-checking picture output condition and the self-checking sound output condition, the self-checking output time of the radar can be set more flexibly and efficiently, and therefore the design requirement of radar self-checking is better met.
According to any of the embodiments described above, in this embodiment:
as shown in fig. 3, before reading the configuration file in the self-checking screen database, the method further includes:
in one alternative, the preprocessing comprises deleting head data, time, position information and other non-radar scanning result data;
and 1004, decoding the real machine radar data, converting the decoded real machine radar data into a preset configuration format and storing the configuration format to obtain a configuration file.
Or before reading the configuration file in the self-test picture database, the method further comprises:
Further, step 1001, that is, the step of obtaining the preset color matrix or the color array includes:
scanning the preset radar image or the preset color range data to obtain a preset color matrix or a color array comprising coordinates and RGB values which are in one-to-one correspondence.
It should be noted that the sequence numbers of steps 1001, 1002, 1003, 1004 do not limit the execution order of these steps, and do not mean that there are no other steps between these steps; before step 102 is executed, the configuration file can be obtained through at least two paths (step 1001 to step 1003, or step 1002 to step 1004).
In the path from step 1001 to step 1003, the preset color matrix or color array may be set directly or obtained by scanning a preset radar image or preset color range data.
In the path from step 1002 to step 1004, the transmission protocol of the true machine radar is the same as that of the self-checking radar.
In a preferred embodiment, the profile acquisition, reading, encoding and decoding process all use the same transmission protocol, for example 661 protocol (ARINC specific 661-2, mercurox, usa under the name of clock DISPLAY SYSTEM INTERFACES TO USER SYSTEMS) for most weather radars.
The beneficial effect of this embodiment lies in:
by providing the specific acquisition step of the configuration file, the method can be compatible with real-machine radar data, the preset color matrix, the preset color array, the preset radar image and the preset color range data as the source of the configuration file, and further the radar self-inspection image can be generated based on the real-machine radar data, the preset color matrix, the preset color array, the preset radar image or the preset color range data through the configuration file, so that the method has better compatibility and use convenience.
According to any of the above embodiments, a complete description of the embodiments will be provided below by taking a meteorological radar as an example.
The meteorological radar is used as airborne equipment for detecting the weather ahead, plays an important role in guaranteeing flight safety, and a meteorological radar self-checking program is a common means for quickly checking whether the function of the meteorological radar has faults or not and is an important judgment basis for judging whether the meteorological radar can provide correct meteorological information return or not. In flight trainees training, entering a weather radar self-checking program is also an important item in conventional training subjects. Because the weather radar self-checking process and the output self-checking picture of different models are different, the self-checking picture is mostly covered on the display screen by the current simulation weather radar self-checking program detection picture, the method does not accord with the requirement of the transmission data format of the real-aircraft weather radar, and the picture display is also different from the real-aircraft weather radar self-checking program.
Aiming at the weather radars of various models and different manufacturers, the self-checking process and the output self-checking picture are different, the configurable weather radar self-checking picture generation method is developed, and the self-checking picture can be reconstructed conveniently.
Because the transmission data of the airborne weather radar is collected and analyzed in the self-checking mode according to the 661 protocol, the standard 708 data can be separated to construct the self-checking picture, which provides possibility for realizing the replacement of the self-checking picture.
Aiming at meteorological radars with different models, a self-checking picture configuration file is generated by imitating the data requirement of a self-checking picture, a meteorological radar simulation model reads the configuration file in a self-checking working mode, model output is calculated according to 708 data in the configuration file, and the data is output to a comprehensive display system to realize drawing of the self-checking picture of the picture. By adopting the method, the generalization of the generation of the weather radar self-checking picture can be realized, and the consistency of the self-checking picture and the self-checking picture of the airborne equipment can also be ensured.
The method for generating the configuration file will be described in detail below;
(1) generation of airborne weather radar data by analytic real-machine
When the real-aircraft weather radar self-checking data can be extracted, the standard self-checking picture 708 data can be directly separated after decoding, the data is stored according to the standard of the configuration file, the required self-checking picture configuration file can be generated, and the decoding and the storage are both software operations without manual operation.
(2) According to self-checking picture generation
If the self-checking data of the real-aircraft weather radar cannot be directly obtained as described in (1), and for the situation, a corresponding configuration file is generated after processing according to the weather radar self-checking picture image of the corresponding model.
The weather radar self-checking picture is generally formed by colors of green, yellow, red, magenta, black and the like, and is in an axisymmetric concentric fan shape.
The self-checking image is identified by Matlab, a coordinate system taking the center of a concentric circle as the origin of coordinates is established, a functional formula of boundaries of different color areas is calculated, which color area each color block on a radar scanning line is located in at a certain moment is judged according to the angle of the radar scanning line, color block color values are returned according to 708 definition, and the whole picture is stored into a two-dimensional color array taking the radar scanning angle as a column and the position of the radar scanning line as a row. And finally, coding the two-dimensional array with the stored colors according to a 708 format to generate a self-checking picture configuration file.
Fig. 6 shows a schematic structural diagram of a typical weather radar simulation system, which will be described in detail with reference to fig. 6 and its operation flow.
1. In the configuration file generation unit, two methods for generating the configuration file are provided, the first method is to read self-checking data of the airborne weather radar, the configuration file generation unit automatically decodes the data, extracts 708 data of a self-checking picture from the data, and finally stores the data into the required weather radar self-checking picture configuration file. Secondly, when there is no way to obtain the self-checking data of the airborne weather radar, the self-checking data can be processed by matlab through the picture of the weather radar picture, and then converted into a picture color two-dimensional array, and after the picture color two-dimensional array is coded into a standard 708 data format, the picture color two-dimensional array is stored into a required weather radar self-checking picture configuration file, and the specific conversion steps are shown in fig. 7.
2. When the Matlab is used for converting the picture into the configuration file, firstly, the boundary of the image needs to be identified, and because the self-checking picture is usually a fan-shaped picture and the picture is axisymmetric, a polar coordinate system can be established by taking the circle center of the fan-shaped picture as an origin; secondly, by identifying boundary lines of different colors, a color boundary line function can be established, and the obtained function is corrected to meet the weather radar scanning line display angle standard; thirdly, identifying the colors of the regions divided by the boundary line functions, and converting the colors into color numbers specified in 708 standard; then, according to the standard of the self-checking picture scanning line of the airborne weather radar, storing the picture processed by the steps into a two-dimensional self-checking picture color numbering matrix by taking the angle of the scanning line as a column coordinate and the distance between a color block and the origin of the coordinate as a row coordinate; and finally, according to the 708 standard, coding the generated color number matrix, and finally generating a required weather radar self-checking picture configuration file.
3. In the weather radar simulation unit, firstly, whether the weather radar simulation unit enters a self-checking mode or not, the weather radar simulation unit reads configuration file data and stores the configuration file data into a self-checking picture database; secondly, when receiving information that the weather radar control panel self-checking button is pressed down or other external simulation systems input self-checking commands to the weather radar simulation unit, the weather radar simulation unit starts self-checking timing if determining that the weather radar simulation unit can enter a self-checking mode after logical judgment.
4. When the timer reaches the self-checking speech output stage, a corresponding self-checking speech signal is generated according to self-checking timing, transmitted to the sound simulation system, and then played by the sound system.
5. When the timer reaches the self-checking picture output stage, the weather radar simulation system reads information from the internal self-checking picture database, recodes the information into image data displayed in the airborne weather radar standard format, transmits the image data to the display simulation system, and then displays the image data after decoding by the display simulation system.
The beneficial effect of this embodiment lies in:
1. the application range is wide.
Although self-checking pictures used in self-checking programs of weather radars of different models are different from manufacturer to manufacturer, the transmission standard of the airborne weather radar is 661 protocol, and the data of the airborne weather radar contains picture information in fixed format, so long as a configuration file storing the picture data is generated for the self-checking image of the weather radar of the corresponding model, and then the self-checking data is modified according to the picture data in the configuration file, the replacement of the self-checking pictures can be realized.
2. The operation is simple.
The replacement of the self-checking picture mainly depends on a weather radar simulation unit to read different configuration files, the configuration file data is stored in a self-checking database after being read, when the weather radar unit enters a self-checking program, the self-checking picture data is read and then is coded into a standard transmission format and then is sent to a display unit, the self-checking picture display can be realized, the configuration files can be automatically generated by codes, therefore, the self-checking picture can be replaced only by replacing the configuration files, and the operation is simple and convenient.
In short, the embodiment is suitable for weather radar self-inspection pictures of all models; the operation is simple and convenient, and manual operation is not needed; the method meets the requirement of the transmission data format of the real-machine meteorological radar and has high simulation precision.
