dSpace adds new safety features to development system
The new functions include a multi-stage watchdog mechanism as well as challenge-response feature that constantly takes the pulse of the real-time processor and ensure correct execution of real-time applications. These features enable users to set the system to a defined status by terminating pending applications and / or resetting the system. In addition, it is possible executing a user-defined software through a non-maskable interrupt that can, for instance, save the last used parameter set or the error code for subsequent analysis. To achieve a higher safety level, the watchdog as well as the challenge response mechanism are implemented on a hardware component independent of the real-time processor. Both mechanisms can be integrated into and configured on Simulink controller models by means of the RTI Watchdog Blockset via drag & drop.
For future releases of the RTI Watchdog Blocksets, dSpace hols out the promise of further functions such as memory integrity checks or monitoring the MicroAutoBox II’s supply voltage level.
