/*
This module is system sleep, the system cannot sleep when the lock exists
To verify whether it is in sleep state, it is necessary to test the power consumption
Power management principle, as long as a wakelock lock exists, the system will not enter the Suspend state
So the name can be arbitrarily chosen to indicate that such a lock is needed so that the system does not sleep
