Das DS2211 HIL I/O Board ist das zentrale I/O-Board für Hardware-in-the-Loop-Simulation, besonders im automotiven Elektronikbereich. Das DS2211 HIL I/O Board ist auf Simulation und Messung automotiver Signale, besonders auf Motor- und Fahrdynamikanwendungen, zugeschnitten und verbindet zahlreiche typische HIL-I/O-Signale auf einem Board. Das DS2211 enthält Signalkonditionierung für typische Signalpegel automotiver Systeme mit 12 V, 24 V und 48 V und unterstützt Bordnetze mit zwei Spannungsebenen.

Aufbau eines HIL-Simulators

Zusammen mit einem Prozessor-Board (DS1006 oder DS1007) bildet das DS2211 HIL I/O Board den Hardware-Kern von dSPACE Simulator. Das Prozessor-Board berechnet das Echtzeitmodell, zum Beispiel eines Motors, während das DS2211 alle benötigten I/O-Signale misst und stimuliert. Werden mehrere DS2211 HIL I/O Boards eingesetzt, kann der Simulator von 8 Zylinder auf 96 Zylinder erweitert werden.

Angular Processing Unit

Das DS2211 HIL I/O Board verfügt über eine einzigartige APU (Angular Processing Unit), die High-Speed-Generierung und –Messung von Kurbelwinkelsignalen unterstützt, um Motoren bis zu 29.000 U/min zu simulieren.

Winkelsynchrones Kaskadieren

Für höhere I/O-Anforderungen können mehrere Boards, zum Beispiel mehrere DS2211, kaskadiert werden. Die Boards arbeiten winkelsynchron, wenn ihre Time-Base-Connectors verbunden sind. Ein DS2211-Board agiert als Zeitbasis (Winkel-Master). Die übrigen Boards lesen dessen Zeitbasis aus, wodurch Signale winkelsynchron auf mehreren Boards generiert und gemessen werden können. Das gleiche gilt für das DS4002 Timing and Digital I/O Board, das DS5001 Digital Waveform Capture Board und das DS5203 FPGA Board, die auch mit derselben Zeitbasis verbunden werden können.

1)The end of life of the dSPACE PHS (peripheral high-speed) hardware for modular systems is planned for December 31, 2024. You can still buy the related products up to and including December 31, 2021. New Releases of dSPACE software will still support the dSPACE PHS hardware for modular systems until at least the end of 2023. After the end of life, no services of any kind will be available for these products. We advise against using the PHS hardware products in new projects. For new projects we recommend that you use SCALEXIO, the latest dSPACE technology for modular real-time systems.
