Abstract
A device and a method for power management of a control apparatus, which control apparatus comprises: a main power source (10), a backup power source (11) and a functional circuit (12). The functional circuit outputs detection information. The power management device comprises a selection circuit (20) suitable for choosing the main power source or the backup power source to supply power to the functional circuit; and a control circuit (21), suitable for switching off the power supply pathway from the backup power source to the functional circuit when the selection circuit chooses the backup power source for supplying power but has not received a trigger signal, and for switching on the power supply pathway from the backup power source to the functional circuit when the selection circuit chooses the backup power source for supplying power and has received a trigger signal.
