[0050] Figure 2 Schematic diagram of the structure of the automated device for testing the flight control system software provided by the present invention. Detailed implementation manners

[0051] Figure 1 It is a schematic diagram of the implementation process of the automated method for testing the flight control system software provided by the present invention. As Figure 1 shown, the specific steps include:

[0052] Step 1: Determine whether there is a target file. If so, execute Step 2; otherwise, re-execute Step 1.

[0053] Step 2: Set the target machine in the loading mode according to the setting of the mode switch specified in the configuration file;

[0054] For example, providing a high level to the mode switch can make the target machine in the loading mode.

[0055] Step 3: Power on the target machine according to the setting of the power switch specified in the configuration file;

[0056] For example, providing a high level to the power switch can supply power to the target machine.

[0057] Step 4: Receive and parse the serial port or network port data, and determine whether the loading mode has been started successfully. If so, execute Step 5; otherwise, end the test and enter Step 2;

[0058] It can be understood that if it has not been started successfully, it can wait for a period of time. After the start is completed, then enter Step 4. It can also be understood that when it fails to start after waiting for a period of time, Step 2 can be re-executed to restart once. It can also be that when the start fails, Step 1 is re-executed and an error message is prompted.

[0059] Step 5: Obtain the target file according to the configuration file;

[0060] It can be understood that one target file is obtained at a time, and the order of obtaining can be in the order of the generation time of the target files.

[0061] Step 6: Load the target file to the target machine through the network port and wait for the loading to complete. If the loading fails, reload it and prompt an error message; otherwise, execute Step 7;

[0062] Step 7: Power off the target machine according to the setting of the power switch specified in the configuration file;

[0063] For example, providing a low level to the power switch can stop supplying power to the target machine.

[0064] Step 8: Set the target machine in the normal operation mode according to the settings of the mode switch specified in the configuration file;

[0065] Step 9: Power on the target machine according to the settings of the power switch specified in the configuration file;

[0066] Step 10: Receive and parse the serial port or network port data, and determine whether the normal operation mode has been started successfully. If so, execute Step 11; otherwise, end the test.

[0067] It can be understood that if the startup is not completed, you can wait for a period of time, and then enter Step 11 after the startup is completed. It can also be understood that you can also re-execute Step 7 to restart once when the startup fails after waiting for a period of time. You can also return to Step 1 and prompt an error message when the startup fails.

[0068] Step 11: Receive the data of the serial port (or the specified port of the network port) and parse it, match the start flag and end flag of the test result, save the valid test result into a file in the specified folder, and store the files formed by one test in one file, and delete the executed target file.

[0069] It can be understood that after the test of a target file is completed, the target file will be deleted, so that the same target file will not be executed multiple times.

[0070] Step 12: Determine whether there is a target file. If so, execute Step 1; otherwise, end the test.

[0071] Figure 2 It is a schematic structural diagram of the automatic device for testing the flight control system software provided by the present invention. As Figure 2 shown, the device includes:

[0072] 1) A mode control module, which is used to control the mode of the target machine. The automatic adaptation device and the automatic adaptation software establish a connection through the network communication module, receive the mode control command issued by the automatic adaptation software, parse the control IO number and IO high and low level status included in the control command, match the corresponding IO interface according to the switch number and high and low level status, set the relay switch to be closed or open, and then feedback the control result to the automatic adaptation software through the network communication module, so as to realize the mode switching of the target machine.

[0073] For example, when the automatic adaptation software finds that there is a loading file, it issues a mode control command. The mode control command specifies a high IO level. At this time, the mode control module sets the relay to be closed according to the high IO level, and specifies a low IO level. At this time, the mode control module sets the relay to be open according to the low IO level.

[0074] 2) Power supply control module, which is used to control the power supply of the target machine. The automatic adaptation device and the automatic adaptation software establish a connection through the network communication module, receive the power supply control instructions issued by the automatic adaptation software, analyze the control IO numbers and IO high / low states included in the control commands, match the corresponding IO interfaces according to the switch numbers and high / low states, set the relay switch to be closed or opened, and then feedback the control result to the automatic adaptation software through the network communication module, so as to realize the power supply control of the target machine.

[0075] For example, when receiving a high-level instruction issued by the automatic adaptation software, the target machine is powered on, and when receiving a low-level instruction, the target machine is powered off.

[0076] 3) Reset control module, which is used to control the reset of the target machine. The automatic adaptation device and the automatic adaptation software establish a connection through the network communication module, receive the reset control instructions issued by the automatic adaptation software, analyze the control IO numbers included in the control instructions, match the corresponding IO interfaces according to the switch numbers, set the relay switch to be closed and opened once each, and then feedback the control result to the automatic adaptation software through the network communication module, so as to realize the reset control of the target machine.

[0077] For example, when the target machine starts up during power supply, if it detects an IO high level, the loading mode is started. If it is a low level, the normal operation mode is started.

[0078] 4) Network port communication module, which is used to communicate with the host computer and the target machine.

[0079] The automatic adaptation device and the automatic adaptation software establish a connection through a custom network communication protocol, which is designed based on the standard Socket communication. The network communication module receives the control instructions issued by the automatic adaptation software, calls other modules to complete the corresponding functions according to the control instructions, and feedbacks the results to the automatic adaptation software through the custom communication protocol.

[0080] The automatic adaptation device receives the target file sent by the host computer and transmits it to the target machine through the network port. And the information fed back by the target machine through the network port is sent to the automatic adaptation software. Among them, the protocol part of the communication between the network and the target machine is implemented by the test adaptation software, and the automatic adaptation device completes the forwarding. Thus, when the communication protocol of different target machines changes, the automatic adaptation device does not need to be updated, and only the automatic adaptation software needs to be modified, which has strong scalability and compatibility.

[0081] 5) The serial communication module is used to receive the target file sent by the network communication module, send the target file to the target machine through the serial port, receive the test result file sent by the target machine through the serial port, and then send it to the automated adaptation software through the network communication module. Among them, the serial communication protocol part is implemented by the automated adaptation software, and the automated adaptation device completes the forwarding. Thus, when the communication protocol of different target machines changes, the automated adaptation device does not need to be updated, and only the automated adaptation software needs to be modified, which has strong scalability and compatibility.
