FwSmDesc_t GetTempCheckSm | ( | ) |
Retrieve the descriptor of the Temperature FD Check State Machine.
The Temperature FD Check State Machine is a singleton. The first time this function is called, it creates and configures the state machine descriptor. Subsequently, it always returns the same descriptor.
The Temperature FD Check State Machine is built as an extension of the generic FD Check State Machine (see FwDaFailDetCheck.h
) with the following changes:
DefAnomalyDetCheck
) is overridden to report "anomaly detected" if the temperature of the hardware device is above HW_DEV_TEMP_MAX_NOM.DefRecoveryAction
) is overridden to start the Temperature Recovery Action Procedure.cntLimit
is set to HW_DEV_TEMP_CNT_LIMIT.Thus, this FD Check monitors the temperature of the Hardware Device and, if it finds that it is out-of-limits for more than HW_DEV_TEMP_CNT_LIMIT consecutive cycles, it switches off the Hardware Device.
