Description

Technical Field

[0001] The invention belongs to the technical field of radar testing, and in particular relates to a Qt-based visualized general radar signal processing interactive system. Background Art

[0002] With the continuous development of my country's radar field, the demands for the reliability, innovation, and stability of radar signal processing systems are also gradually increasing. Faced with the huge market demand in the future, research and development in the radar field faces challenges such as tight time schedules, difficult technological innovations, and heavy quality tasks.

[0003] The need for efficient debugging of radar signal processing systems. Radar signal processing systems are the core technology in the radar field and represent the highest level in the radar field. They are faced with challenges such as tight time schedules and heavy quality tasks. In order to shorten the debugging time of the signal processing system, the development of a visual general radar signal processing interactive system is very necessary.

[0004] The need for big data analysis of radar signal processing systems. The internal data of radar signal processing systems has the characteristics of many types of data, high data rate, and huge data volume. In order to realize the analysis of data at each processing node, data storage and analysis are indispensable. The visual general radar signal processing interactive system successfully realizes the data storage and analysis functions.

[0005] The need for debugging the radar signal processing system interface. There are many types of radar signal processing system boards, including FPGA boards, DSP boards, CPU boards, storage boards, etc., and the types of interfaces involved are very rich, so the debugging of various interfaces becomes very complicated. The visual universal radar signal processing interactive system can effectively solve the problem of complex interface debugging. It debugs each interface through the UDP network, greatly reducing the complexity of interface debugging.

[0006] The need for visualization of radar signal processing systems. In the prior art, radar signal processing systems can only display waypoints with the cooperation of the display and control console during the vehicle debugging stage, which brings a lot of inconvenience to the debugging of radar signal processing systems. In order to reduce the error probability and improve the combination stability during the vehicle debugging stage, visualization function is required during the combination debugging stage. The visualized universal radar signal processing interactive system can replace the display and control console to realize the real-time display, storage and playback functions of waypoints during the combination debugging stage.

[0007] The need for manual intervention in the radar signal processing system. At the vehicle level, the manual intervention command for the radar signal processing system is issued by the display and control console. To facilitate combination debugging, the visual universal radar signal processing interactive system can replace the display and control console to issue manual intervention commands to the radar signal processing combination through the network, which increases the convenience of debugging and greatly shortens the debugging time of the whole vehicle.

[0008] In view of the above, it is necessary to propose a design method for the host computer software of a Qt-based visual general radar signal processing interactive system. This invention will greatly shorten the debugging cycle, reduce the manpower and material costs of debugging, and accelerate the progress of radar research and development and production.

[0046] The following is a further detailed description of a Qt-based visualized general radar signal processing interactive system proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0047] Example

[0048] See also Figure 1 This embodiment provides a Qt-based visual general radar signal processing interactive system, including a control module, a transmission module and an execution module. The control module is connected to the execution module signal via the transmission module to control the execution module. The control module can be understood as an upper control module, which includes a storage board control unit, an FPGA board control unit, a DSP board control unit, a CPU board control unit and a timing board control unit.

[0049] The execution module can be understood as a module that performs related operations, which includes an FPGA board, four DSP boards, a CPU board, a timing board, and a storage board. They are respectively controlled by the FPGA board control unit, the DSP board control unit, the CPU board control unit, the timing board control unit, and the storage board control unit to perform corresponding operations. The storage board is controlled by the storage board control unit to store data of the FPGA board, the DSP board, the CPU board, and the timing board. The transmission module is Ethernet, and each unit in the control module is connected to each unit of the execution module one by one.

[0050] Before the implementation of this embodiment, it is necessary to create an environment that can carry and implement this implementation. First, create a project, add three standard libraries, coregui, network and xlsx, in the .pro file, and add external libraries QWorks.dll (embedded middleware), resource files .qrc and style files .qss in addition to source files and header files. Call the function setStyleSheet() in the main() function of the project to load the custom QSS style file to realize the personalized customization of the operation interface, that is, to visualize the above-mentioned control units. Display the instantiated main form object MainWindow, and finally return exec() at the end of the main() function to make this embodiment enter the event loop.

[0051] For the main window object MainWindow, the specific construction steps are as follows:

[0052] A1: First, initialize the network communication with the execution module, call the QWorks_AddUDPIP() function to establish the communication link between the control module and the FPGA board, CPU board, DSP board, and timing board, and call the QWorks_AddNFIP() function to establish the communication link between the control module and the storage board.

[0053] Next, A2: calls the QWorks_Initialize2() function to initialize the embedded middleware driver of the execution module, scans the devices of various interfaces, and cyclically scans until the function return value is 0, which means the initialization is successful.

[0054] Then, A3: initialize the controls of the main form. The main form mainly includes two sub-pages, the main interface and the health management page. The main interface is used to display the actual rendering of the radar signal processing combination. Multiple buttons are used to realize the display of each board sub-interface. Each board has a communication link indicator. Green indicates a successful connection and red indicates a failed connection. Clicking each button can pop up the sub-interface of each board, including the FPGA board control interface, the DSP board control interface, the CPU board control interface, the timing board control interface, and the storage board control interface. Each control interface can be understood as a visual interface of each control module.

[0055] Health management page, the visual interface of the health management module, is used to monitor the BIT information of each subsystem of the radar, including array power supply, water cooling monitoring, frequency management unit, waveform generator, wave control machine and signal processing, servo system, and ground interrogator. Seven buttons pop up their own sub-interfaces to display BIT abnormalities in real time. Red represents abnormalities and green represents normal conditions. Initialize the network socket to receive UDP network messages, and finally initialize global variables.

[0056] Specifically, see Figure 2and Figure 3 For the storage board control unit, first you need to create a new storage board control interface, that is, visualize the storage board control unit. The storage board control interface is mainly used to control the data storage of FPGA boards, DSP boards (4), CPU boards, and timing boards. Data storage is achieved by switching the data nodes of each sub-board. It calls the function QWorks_QM2Exec(0,"CTRW",nf_arg_buf) to send a node selection command to the storage board, switches the storage board data node to the corresponding SRIO multicast port, calls the function QWorks_QM2Exec(0,"SAMP",fname) to control the storage board to start storage, and calls the function QWorks_QM2Exec(0,"STSA",nf_arg_buf)) to control the storage board to stop storage. The size of each data file on the storage board can be set. The default is 1G, and 256MB\512MB\1G can be selected. The data storage of different data types of each board is controlled by the 25 buttons set on the storage board control interface. Click the button to start storage control, and press the button again to stop storage control.

[0057] Specifically, see Figure 2 , create a new FPGA board control interface, that is, visualize the FPGA board control unit.

By entering index number and number of data packets, the data file corresponding to the specified message can be stored. The file format is txt file, where the index number is EXCEL file line number -2, the number of data packets is not limited, and continuous multiple frames of data content can be stored for data analysis.

[0060] The channel correction sub-unit builds a channel correction sub-interface in the FPGA board control interface, that is, visualizes the channel correction sub-unit. The channel correction sub-unit is used to draw the data curve before and after correction. By browsing and selecting the channel correction file stored in the storage board, and then drawing, the QCustomPlot class is used to realize the drawing of the curve before and after the channel correction.

[0061] Specifically, see Figure 2 , create a new DSP board control interface, that is, visualize the DSP board control unit. The DSP board control unit includes three sub-units: DSP data analysis sub-unit, error display sub-unit and curve drawing sub-unit. The specific implementation of the three sub-units is as follows.

[0062] Construct a DSP data analysis sub-interface in the DSP board control interface, that is, visualize the DSP data analysis sub-unit. The DSP data analysis sub-unit is used to parse the DSP data stored in the storage board. Select the data file to be parsed by browsing the button, click the OK button to parse the general message information of the radar signal processing system, click the Import EXCEL button, and write the parsed message data to EXCEL by calling the function xlsx.write(). By entering the index number and the number of data packets, the data file corresponding to the specified message can be stored. The file format is a txt file, where the index number is the EXCEL file line number -2, and the number of data packets is not limited. It can store multiple frames of continuous data content for easy data analysis.

[0063] An error display sub-interface and an error display sub-unit are constructed in the DSP board control interface to print out error information such as packet loss and frame loss of the DSP board in real time.

[0064] Construct a curve drawing sub-interface in the DSP board control interface, that is, the curve drawing sub-unit visualization.

[0065] Specifically, see Figure 2 , create a new CPU board control interface, that is, visualize the CPU board control unit. The CPU board control unit includes four subunits: PPI display subunit, storage and playback subunit, precision analysis subunit and instruction control subunit. The four subunits are specifically implemented as follows.

[0066] Construct the PPI sub-interface, that is, the visualization of the PPI display sub-unit. The PPI display sub-unit is used to display the target track information in real time.

After receiving the data packet, it determines whether it is the point track data that needs to be displayed, and parses the target information such as azimuth, pitch, distance, speed, target type, batch number, etc. in the point track data. By calling the update() function to trigger the paintEvent event, the PPI sub-interface is refreshed. The function TgtRefresh() is called regularly through the timer QTimer to refresh the target list. If it is a new batch number, a row is added. If it is an existing batch number, the corresponding row is updated. If the target information is not updated for three consecutive laps, the batch number target is deleted from the target list.

[0067] The storage and playback subunit is used to store and dynamically and statically playback point tracks and tracks. Storage function: click the browse button, select the file storage path, click start recording, start storing the point track data package, the button content changes to stop recording, the file type is a txt file, each data package is stored by line, click stop recording again to stop storing data.

All data files are read by calling the readLine() function in a loop and stored in a two-dimensional array by line. After reading all data files, the SlowReview() function is called regularly through the QTimer timer. Each time a row of data in the two-dimensional array is parsed, the azimuth, pitch, distance, speed, target type, batch number and other target information in the point track data are parsed. The paintEvent event is triggered by calling the update() function to refresh the PPI interface and realize slow / fast playback of point tracks.

The target track data is smoothed by moving the sliding window, the fitting coefficient is calculated, the measured value and the fitting value at the same time are compared, the system error and the fluctuation error are calculated after eliminating the wild value, and the calculation results are displayed. Through the global variables, the track data is passed to the precision analysis subwindow for two-dimensional drawing. The radioButton can be used to select one of the tA curve / tR curve / tE curve to be drawn. Each type of curve includes two curves: the original track and the track fitting curve.

[0070] Specifically, see Figure 2, create a new timing board control interface, that is, visualize the timing board control unit.

The timing data analysis sub-unit is used to parse the timing board data stored in the storage board. Select the data file to be parsed by browsing the button, click the OK button to parse the general message information of the radar signal processing system, click the Import EXCEL button, and write the parsed message data to EXCEL by calling the function xlsx.write(). By entering the index number and the number of data packets, the data file corresponding to the specified message can be stored. The file format is a txt file, where the index number is the EXCEL file line number -2, and the number of data packets is unlimited. It can store multiple frames of continuous data content for easy data analysis.

[0072] Construct a timing diagram sub-interface in the timing board control interface, that is, visualize the timing diagram sub-unit. It is used to draw the timing diagram under different working modes of the radar. Select the timing data stored by the storage board through the browse button, click the drawing button, and draw the timing diagram through the QCustomPlot class.
