[0002] Missile testing constitutes a significant portion of the workload during missile development, production, and deployment. Its purpose is to verify the functionality and key technical performance of the entire missile system or its subsystems. It can also guide adjustments to relevant performance parameters, pinpoint faulty components, and ensure the missile is in good operational condition during missile development.

[0003] Missile testing requires integrated missile testing software. The testing requirements vary significantly depending on the missile model, resulting in highly specialized but limited scalability and low code reusability in the development of integrated testing software. Therefore, developing user-friendly, reliable, easy-to-maintain, and highly scalable integrated missile testing software can play a crucial role in the missile research and production process, effectively improving work efficiency. Summary of the Invention

[0026] This invention utilizes the QT platform based on C++, leveraging C++'s object-oriented technology and QT's unique signal-slot mechanism to develop missile integrated testing software.

Attached Figure Description

[0028] Figure 1 This is a structural diagram of the missile integrated testing software of the present invention. Detailed Implementation

[0029] To clearly illustrate the technical solution of the present invention, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0030] This invention provides a method for implementing missile integrated testing software based on object-oriented technology, comprising:

[0031] Create a main window class, and create functional subclasses within the constructor of the main window class. These subclasses include a data receiving class, a data sending class, a functional testing class, a software upgrade class, and a waveform chart drawing class.

[0032] Define signal functions and slot functions in each of the created classes, and establish corresponding connections between the main window class and its subclasses, as well as between the subclasses and their signal functions and slot functions.

[0033] Create a main window thread for displaying and refreshing the main window class;

[0034] Create a sub-thread for receiving and parsing data, which is used by the data receiving class to receive and parse network interface data;

[0035] A data sending sub-thread is created for the data sending class to issue control commands from the host computer.

[0036] The main window class contains objects of data receiving encapsulation classes, data sending encapsulation classes, software upgrade encapsulation classes, functional testing encapsulation classes, chart drawing encapsulation classes, and indicator light and button style changing encapsulation classes, which are used to complete the functions of their respective classes.

[0037] Define functions for obtaining missile cycle data slots, command byte data packet signals, and command sending slots within the main window class;

[0038] The front panel controls of the main window include the main missile status value display controls, status indicator LEDs, and important single-machine data waveform chart display controls. The waveform chart drawing class is used to update the front panel controls of the main window class. A zoom button click function is created in the front panel controls, and an XY axis range zoom function is defined in the waveform chart drawing class. The zoom button click function sends a chart zoom signal to the waveform chart drawing class, which responds to the XY axis range zoom function. Dynamic chart zooming is achieved by changing the number of display points on the horizontal axis and the range of the vertical axis.

[0039] This is a waveform chart drawing class used to dynamically draw waveform charts, complete the drawing and dynamic data refresh of waveform charts for servo angles, add-in data, and gyroscope data in the main window; it also enables the scaling function of waveform charts.

[0040] Define a waveform chart class. The main private members of this class include the number of data points in the waveform chart, and the class member functions include functions for creating waveform charts, adding data to curves, and refreshing charts.

[0041] The data receiving class is used to receive and parse network data in the data receiving and parsing sub-thread, and send signals to the main thread to refresh the interface controls and display waveform charts.

[0042] The specific implementation method is as follows: Define a data receiving class and encapsulate it. The main private members of this class include UDP network interface, data classification and parsing file saving interface, text stream interface, etc. The main class member functions include network interface raw data receiving function, raw byte data parsing function, periodic data parsing function, non-periodic data parsing function, parsing data saving function, etc.

[0043] In the main program, an object of the data receiving class is created and placed in a sub-thread for data receiving and parsing. This sub-thread handles the parsing and storage of periodic and non-periodic data from the lower-level machine. A missile periodic data signal function is defined within the data receiving class. After receiving missile data cyclically via the network port, the function parses the data, packages the parsed data into a structure, and sends the missile periodic data signal to the main window class. Upon receiving the signal, the main window class responds with a function to retrieve the missile periodic data slot. This function updates window control values, status lights, and refreshes waveform charts. The window's display controls are dynamically refreshed based on the received data. Here, the waveform chart class plays a crucial role, primarily handling tasks such as adding chart data, dynamically refreshing the chart display, and scaling the display area.

[0044] The data sending class is used to send control commands from the host computer, as well as software upgrades and data packet bindings, in the data sending sub-thread.

[0045] The specific implementation method is as follows: Define a data sending class and encapsulate it. The main private members of this class include the UDP network interface, the instruction save file interface, the text stream interface, the array of sent byte data, etc. The main class member functions include the sent byte data initialization function, the instruction byte data generation function, the software upgrade and information binding data packet generation function, the network interface data sending function, etc.

[0046] In the main program, create an object of the data sending class and place it in the created data sending sub-thread. In the data sending sub-thread, implement the sending of host computer control commands, software upgrades, and information binding data packets, and store the sent data content to a file.

[0047] Define a function in the data sending class to retrieve command data packet slots, used to respond to control commands or software upgrade data packets sent from the main window. Create click slot functions for the function buttons on the main window's front panel to send command signals to the data sending class. Different types of commands are categorized and packaged by creating command data packet structures. The data receiving class receives the command data structure and then decomposes it to obtain the corresponding command. The process for responding to software upgrade commands is similar, the difference being the size of the data packet.

[0048] The functional test class is used to complete functional tests such as integration testing, simulated flight testing, and polarity checks. It acquires servo angle data, gyroscope data, and gauge data to determine whether the test items pass or fail.

[0049] The specific implementation method is as follows: Define a functional test class. The main private members of this class include the pop-up number, functional test type, test result file saving interface, test standard data array, etc. The class member functions include the test type setting function, the test result judgment function, and the test result writing file function, etc.

[0050] In the functional test class, a test instruction data packet signal function is defined and connected to the instruction sending slot function of the main window class. The main window class forwards the test instruction data packet signal function to the data sending class. The data sending class responds with the instruction data packet slot function, thus sending the test step instructions to the data sending thread. Simultaneously, the main window class continuously receives missile data from the data receiving class, and determines whether the functional test class should continue sending the next test step, pause sending, or stop the test altogether by judging certain specific conditions. This establishes a closed-loop process involving the main window class, functional test class, data receiving class, and data sending class, used to complete each missile functional test.

[0051] Software upgrade category, used to realize functions such as flight control software upgrade, simulated flight software upgrade, simulated flight data binding, and missile information binding.

[0052] The specific implementation method is as follows: Define a software upgrade class. The main private members of this class include a 1024-byte array, the number of bytes in the binary file, the successful upgrade frame count, and the maximum frame count. The main class member functions include an initialization function, a function to get the maximum frame count of the binary file, a function to open the binary file, a function to extract a frame (1024 bytes) from the header, a function to generate a binary file for information binding, and a function to generate a binary file for flight simulation.

[0053] A software upgrade data signal function is defined in the software upgrade class. When the corresponding upgrade button is clicked in the main window, the data sending class receives the upgrade command sent by the main window class, preparing for the upgrade process and establishing a connection. At this time, the software upgrade class completes tasks such as reading the upgrade binary file and determining the upgrade frame count. Then, the software upgrade class sends the software upgrade data signal function to the data sending class. The data sending class responds with the function to obtain the command data packet slot, sends the upgrade data packet to the data sending thread, and determines whether the upgrade process is normal based on the data received by the main window and the missile upgrade status data sent by the sub-thread. Based on the feedback status, it chooses to continue sending the next frame, resend the current frame, or stop the upgrade.

[0054] Within the constructor, a style modification class is also created. By setting different styles for indicator lights and buttons (including text display, font color, size, background color, etc.), the interface (LED) display effects in different states are achieved, as well as the display differences between pressing and releasing different types of buttons.

[0055] This invention develops missile integrated testing software by creating multiple classes. The structure of the missile integrated testing software is as follows: Figure 1 As shown in the figure, this software is reliable, easy to maintain, and highly scalable, effectively improving work efficiency. This invention achieves coordinated operation of multiple software functions by creating multi-threaded interfaces, enhancing both software efficiency and user experience, and preventing issues such as main window freezing, inability to refresh charts, and failure to respond to user actions. The main thread consists of a main window thread, data receiving and parsing sub-threads, and data sending sub-threads. Data communication between the main thread and sub-threads, and between sub-threads themselves, is achieved through signals and slots.
