Abstract

Modern high-end technology products such as aircraft consist of a number of individual systems that are controlled by independent electronic control units and increasingly interconnected. According to one exemplary embodiment of the present invention, a test system assembly for testing several such systems for an aircraft in parallel is disclosed, wherein a master network is provided in order to exchange data between the individual test systems and a control unit, and wherein original electrical wiring is provided between the test systems in order to directly interconnect the tested systems. The flexibility of system tests for aircraft may be increased in this fashion.

Claims

1. A test system assembly for testing several systems under test for an aircraft in parallel, with the test system assembly comprising:

a first test system for simulating a first electrical environment of a first system under test;

a second test system for simulating a second electrical environment of a second system under test; and

a master network designed for data exchange between the first and second test systems and for data exchange with a workstation for controlling test sequences.

2. The test system assembly of claim 1,

wherein the network is designed for transmitting management and control parameters of a test sequence only.

3. The test system assembly of claim 1,

wherein each test system is designed for data exchange with every other test system and with the workstation.

4. The test system assembly of claim 1,

wherein a third test system is provided for simulating a third electrical environment of the first system under test.

5. The test system assembly of claim 1,

wherein the first test system is designed for assuming a closed functionality of the first system under test.

6. The test system assembly of claim 1,

wherein the test systems include switches for switching through signals of the systems under test to other systems.

7. The test system assembly of claim 1,

wherein the workstation is designed for controlling and configuring the test sequences.

8. The test system assembly of claim 1, further comprising:

a data memory for storing measuring data resulting from the test sequence via the network.

9. The test system assembly of claim 1, further comprising:

another workstation for monitoring and controlling other test sequences.

10. The test system assembly of claim 1, further comprising:

another test system for controlling the first test system and for carrying out a simulation calculation.

11. The test system assembly of claim 1,

wherein the test system assembly has an online operating mode, in which the test systems simulate an original environment of the systems under test.

12. The test system assembly of claim 1,

wherein the test system assembly has an offline operating mode, in which a configuration of the test systems can be carried out in preparation for a new test sequence.

13. The test system assembly of claim 1, further comprising:

electrical wiring that corresponds to an original connection of the systems under test.

14. The test system assembly of claim 1, wherein the network comprises a subgroup that only serves for the exchange of process variables between the test systems.

15. The test system assembly of claim 1, wherein the test systems are interconnected in such a way that they respectively simulate a system under test in its entirety such that the test system assembly can carry out tests of the connected system without the presence of original components.

17. An aircraft connected to a test system assembly of claim 1.

18. Components of an aircraft connected to a test system assembly claim 1.

19. A test system for a test system assembly of claim 1, wherein the test system is designed for outputting an inventory report on a status of a hardware equipment and on properties of this hardware, as well as for outputting an inventory report on all simulations loaded in the test system and their properties.
