Abstract

A system integration test rig for networked overall mechatronic systems includes mechanical and/or electronic components in the form of a mathematical model or real assemblies. According to the invention, the mechanical and/or electronic components are provided in the form of modules, each having its own power supply. The modules can be operated in a spatially distributed form, and communicate with one another via a communication link with a real-time capability, preferably via an Ethernet link. The modules can also operate autonomously.

Claims

1. A system integration test rig for a networked mechatronic system, the test rig having mechanical and/or electronic components in the form of a mathematical model and/or real assemblies;

wherein;

the components are in the form of modules;

each module has its power supply; and

the components are operable in a spatially distributed form and communicate with one another in real time via a communication link.

2. The system according to claim 1, wherein said network comprises one of the Internet, an organization network and an Ethernet.

3. The system integration test rig as claimed in claim 2, wherein the modules are distributed over a plurality of development sites and communicate with one another via the Internet using protocols, with a real-time capability.

4. The system integration test rig as claimed in claim 3, wherein at least one module removable from the system integration test rig and can be operated independently as an individual test rig or as a test rig element.

5. The system integration test rig as claimed in claim 4, including a control computer for controlling at least one of the system integration test rig, the individual test rig, and the test rig element.

6. The system integration test rig as claimed in claim 5, wherein each module is in the form of one of an engine module, a transmission module, an instrument module, and a window module.

7. The system integration test rig as claimed in claim 6, further comprising a standardized rack for holding the individual modules.

8. A module for a networked mechatronic system, the test rig having mechanical and/or electronic components in the form of a mathematical model and/or real assemblies, said module comprising:

an electronics area with at least one of an actuator and sensor functionality, for production of appropriate actuator or sensor signals;

an interface area with a real-time computer system for simulation control and with a signal preprocessing area; and

a standard power supply unit for supplying power to the module.

9. The module as claimed in claim 8, further comprising a distributor area to which controller signal lines are connected directly and in which blade isolating terminals, signal distributors or apparatus for automatic introduction of signal interruptions or short-circuits are accommodated or connectable.

10. The module as claimed in claim 9, further comprising at least one standard coupling module with connections for connection of at least one of servicing appliances, diagnosis appliances and controllers.
