Description

System architecture of redundancy management automatic test system

Technical Field

The application belongs to the field of automatic testing, and particularly relates to a system architecture of a redundancy management automatic testing system.

Background

The redundancy is a means for improving the reliability and safety reliability of system tasks, and the redundancy technology is widely applied to the aspect of aerospace flight control. Typically, the testing of the redundancy system includes a redundancy management policy test, an amplitude threshold test and a time threshold test. The test content is many and complex, for example, a flight control system needs hundreds of signals such as total pressure, static pressure, pitch angle rate, roll angle rate and the like to test, and the automatic test of the signals is necessary to realize.

The existing automatic test system has the structural characteristics that:

1) the test signal generation program, the data storage program, and the data analysis program are not separated, and are programs under the same project. Its advantages are compact integral program; the method has the disadvantages that the method is suitable for one person to develop, the program Bug is easy to spread, and one program Bug can search and change the whole program.

2) The signal testing is performed serially. The method has the advantages that whether the realization of the tested signal is correct can be observed in real time when each signal is tested; the disadvantage is the slow testing process.

3) And testing each signal by using a test case of the signal, wherein the test case comprises the whole test process of the signal. The advantage is that all signal tests use one program, the appearance looks good; the method has the disadvantages of difficult test case compiling, need of a large amount of professional personnel to specially compile and extremely low efficiency.

Therefore, how to improve the efficiency of the redundancy signal test is a problem to be solved.

Detailed Description

In order to make the implementation objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.

A system architecture of a redundancy management automatic test system is shown in FIG. 1, and comprises a signal generation program unit 1, a data storage program unit 2 and a data analysis program unit 3.

The signal generating program unit 1 is used for receiving and adopting a test program to test the redundancy signal and outputting test data; the data storage program unit 2 is used for receiving the test data of the signal generation program unit 1 and storing the test data in a classified manner; the data analysis program unit 3 is used for calling the test data from the data storage program unit 2 and analyzing the test data

When a group of redundancy signals are analyzed, the redundancy signals are firstly transmitted into a signal generation program to be tested, a test result is transmitted to a data storage program unit 2 to be classified and stored according to the types of the redundancy signals, then the redundancy signals are subjected to data analysis through a data analysis program, and the automatic test of the redundancy signals is completed at the later stage after the analysis is completed.

The three units form a system structure with separate tests, are independent from each other, can run on one computer and can also run in different computers, and therefore the bug isolation is achieved. The three programs can be developed by different personnel, and the labor division is clear; the program test is simple, and a single program Bug cannot influence other programs, so that the working efficiency is effectively improved, the working difficulty is reduced, and the occurrence of errors is reduced.

As shown in fig. 2, preferably, in the signal generating program unit 1, all test programs that are not interfered by other test programs, such as a Wx test program, a Wy test program, a static pressure test program, and a dynamic pressure test program, can be simultaneously run, and the implementation manner is to use Simulink to simulate and build the test program, compile the test program into an operating system (such as a VxWorks or xPc real-time system) that runs in real time, and run the program in the real-time system.

Most of test programs can run in parallel, the signal generation program unit 1 can receive different test signals at the same time, and different test programs are selected for testing, so that the test efficiency is greatly improved.

Preferably, in the signal generating program, a plurality of program subunits which run simultaneously can be arranged inside, and different redundancy signals can be tested simultaneously and respectively.

The same kind of signals have the same test algorithm, for example, the same test procedures are the Wx test procedure, the Wy test procedure, the static pressure test procedure and the total pressure test procedure of the four-redundancy signals, but the test procedures are the same, and only the input is different (twelve major characteristics of a certain signal), and the output data structure is the same.

Therefore, the similar test algorithm can be copied and used only by compiling once, and unlike the previous test case, each test signal needs to compile a test process (algorithm) independently, so that the working intensity is greatly reduced, and the occurrence of errors is reduced.

Like the standard test algorithm, the data analysis algorithm for the same kind of signal is also the same, except that the inputs are different (twelve major features of a certain signal), and the output data structure is also the same. The data analysis algorithm adopts a standard algorithm, and details are not repeated.

Therefore, the data analysis algorithm of the same kind of signals can be copied and used only by compiling once, and unlike the prior test case, each test signal needs to compile an analysis process (algorithm) independently, thereby greatly reducing the working intensity and reducing the occurrence of errors.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
