[0090] The rapid development, verification and debugging environment equipment for the airborne core processing platform of this application provides all the excitation signals required for the three modules of the airborne core processing platform, namely the general processing module (DPU), the network processing module (FNU) and the intelligent processing module (IPU), including discrete quantities, serial ports, network ports and FC / TSN bus signals. Through the operation and setting of the airborne core processing platform development environment equipment, the output control of various excitation signals can be completed, the detection of hardware interface resources can be realized, and support can be provided during the development, debugging and test verification of finished products. Figure 1 Shown is an overall schematic diagram of the rapid development, verification and debugging environment equipment for the airborne core processing platform.

[0091] The rapid development, verification and debugging environment equipment for the airborne core processing platform of this application can be divided into two parts: hardware architecture and software solution. Among them, the 28V power supply test module, discrete input module, discrete output module, RS232 serial communication module, Ethernet communication module, FC / TSN simulation module and FC / TSN monitoring module constitute the hardware architecture, and the test software and intelligent unit development environment constitute the software solution.

[0155] The automatic test module automatically reads the test process information pre-configured in the database through the program to form a test number. After the operator checks the relevant test items, the test program thread is started. The test thread controls the stimulus loading signal or sends the test data packet according to the general control process, and receives the data packet or operation signal through the expectation. Then, the test result is judged according to the solution algorithm corresponding to the expectation. After completion, the result is displayed on the interface and the next test is continued. After all tests are completed, records and report files are formed.

[0156] The execution flow chart of the test software is as follows: Fig.11 As shown. After the user starts the program, the software first displays the startup interface to check whether the license is correct. If the license verification fails, the application program will be exited directly. After the license verification succeeds, the software checks the configuration database, loads the configuration information, and completes the initialization of the software interface in the startup interface. Then the module self-test interface is displayed, and the software automatically starts the self-test. According to the configuration information, the board card is opened, the serial port channel is configured, and the board card and the serial port are checked to see if they are normal and the self-test results are displayed. If the board card works normally, the function selection interface is entered, and the user can further choose to perform test operations. If there is an abnormality, the board card or serial port fault error information is prompted. If the hardware resources work normally, the main test interface is entered normally.

[0157] After entering the main test interface, the test software designs a hard-line signal acquisition thread HardwareInput() to collect analog inputs of the total power supply voltage and current and each channel voltage and current as well as discrete input signals. This thread is created by the CreateHardwareInput_Thread() function and destroyed by the Release_HardwareInput_Thread() function before the software is closed.

[0158] The user can switch between interface tests and working status tests by switching the Tab label options. The main interface and other interfaces are completed in the form of menu callback, and the calls between interfaces are completed in the form of button callback, which further completes signal calibration, operation self-test, user management and help operations.
