APEX ORIN NX II Input Voltage Monitoring

Functions

Voltage monitoring checks voltage status at the system level, primarily to investigate the effects of input voltage fluctuations.

It also helps determine whether a system shutdown or restart was caused by an unstable power supply.

Usage

/opt/miivii/features/power_query/bin/power_query

Last Power failed time: 2022-08-08 17:47:05 #Time of the last unexpected power loss, in the system time zone.

Last Power failed voltages:
DC_in_volt:         13.631V #Voltage at the last unexpected power loss; a software shutdown does not change this value.

System running voltages:
DC_in_volt:         22.768V #Current system voltage

Typical Application

Unexpected Device Shutdown

On August 9, 2022, the device was found powered off.

Run the following command to obtain the data shown below.

The output shows that the input voltage dropped to 13.631 V at 17:47:05 on August 8, 2022, compared with the normal voltage of 22.768 V.

The input power supply should therefore be checked.
