Description

Technical Field

[0001] This invention relates to the field of aero-engine control software technology, and more specifically to an aero-engine lifespan data storage and verification method based on data stream segmentation. Background Technology

[0002] The verification of aero-engine life data and continuous data storage differs from other functional tests. The data is stored inside the controller, making it impossible to observe the execution status in real time via serial port and bus communication. After the test is completed, the life data and continuous data need to be downloaded from the controller to observe the execution status. The whole process is quite complex and not easy to automate. Therefore, the verification of aero-engine life data and continuous data storage relies on manual completion. Moreover, the life data and continuous signal volume are very large, making complete verification time-consuming and labor-intensive. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a method for verifying the storage of aero-engine lifespan data based on data stream segmentation. This method divides the verification of lifespan data and continuous data storage functions into two parts: data packet filling verification and data packet storage verification. This significantly improves the efficiency of the testing work while ensuring the validity and integrity of the test results, thus solving the problems existing in the background technology.

[0005] Furthermore, in step (1), the data packet filling verification is as follows: test cases and verification procedures are automatically generated according to the pre-made configuration file; verification is automatically executed in the microcontroller board-level environment, and the verification content includes the data boundary values, fixed-point storage precision, byte offset and word offset storage location; and a test report for data packet filling verification is automatically generated.

[0006] Furthermore, in step (1), the data packet storage verification is as follows: verifying the start and end timing of data storage; verifying the circular storage function; verifying the data storage behavior under abnormal conditions.

[0007] Furthermore, the configuration file includes signal type, boundary values, storage precision, and storage location attributes.

[0008] Furthermore, in step (2), the microcontroller board environment uses the same model of microcontroller as the target machine environment.

[0009] Furthermore, in step (3), after completing the data packet filling verification and data packet storage verification, a complete lifetime data and continuous data storage function verification report is generated.

[0010] The aero-engine lifespan data storage and verification system based on data stream segmentation described in this invention includes: The partitioning module is used to verify the storage function of lifetime data and continuous data, and is divided into two parts according to the data flow: data packet filling verification and data packet storage verification. Microcontroller board-level module: Used to perform data packet filling verification in a microcontroller board-level environment to verify data boundary values, storage precision, and storage location; Target machine module: Used to perform packet storage verification in the target machine environment to verify the normal and abnormal functions of data storage; packet stuffing verification and packet storage verification are performed independently, and together they constitute a complete verification of the lifetime data and continuous data storage functions.

[0013] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: This invention divides the verification of lifetime data and continuous data storage functions into two parts according to the data flow: data packet filling verification and data packet storage verification. The data packet filling process is automated: based on the configuration file, test cases and verification procedures are automatically generated, automatically verifying data boundary values, storage precision (fixed-point), storage location (byte offset, word offset), etc., and automatically generating a test report. The operating environment is a microcontroller environment of the same model as the target machine environment: the operating environment for the data packet filling verification process is a microcontroller board-level environment of the same model as the target machine environment; the operating environment for the data packet storage verification process is the target machine environment.
