Piling method of control law software

Abstract

The invention discloses a piling method of control law software and belongs to the technical field of airborne software testing. The method specifically comprises the following steps that firstly, thestructure of a to-be-tested control law module is analyzed, and pile modules needing piling are determined; according to the operation process in the to-be-tested control law module, a required low-layer module is determined, and the low-layer module is piled; secondly, global variables are defined; thirdly, a pile program corresponding to each pile module is compiled; fourthly, a driving moduleis generated by using a software testing tool, the to-be-tested control law module is called, and a testing result is output; fifthly, whether the test output result is consistent with an expected output result or not is analyzed; if the test output result is consistent with the expected output result, it means that a source code is consistent with the software design; otherwise, the difference ofthe results needs to be analyzed, the position of a problem is determined, and a software regression test is carried out till the problem returns to zero. The method can only pay attention to influences of return values of the pile modules on the to-be-tested module, and the test efficiency and the correctness of the modules are improved.

Description

technical field [0001] The invention belongs to the technical field of airborne software testing, and in particular relates to a piling method for control law software. Background technique [0002] The fly-by-wire flight control system uses the flight control computer as the control core. It controls and solves various information such as the pilot's manipulation and the amount of movement of the aircraft sensed by the system sensors. control. As the core software, the flight control law software realizes the performance and flight quality requirements of the aircraft, so its design complexity is high. [0003] During software unit testing, the stub function entry parameters passed by local variables are released and disappear after the module runs, and the correctness of local variable calculations cannot be verified.

As the core software, the flight control law software realizes the performance and flight quality requirements of the aircraft, so its design complexity is high

[0003] During software unit testing, the stub function entry parameters passed by local variables are released and disappear after the module runs, and the correctness of local variable calculations cannot be verified. However, the output data of the flight control law software is continuous, and the software The "small errors" in the system may not be stimulated in the continuous output data within a limited time, and the "small errors" may become the fuse that endangers the safety of flight life, and a lot of manpower, material and financial resources are required to make mistakes in the later stage.
