Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
Be illustrated in figure 1 as the structural representation of the electric supply installation of the embodiment of the invention, described electric supply installation (PSU, power supply unit) 100 is applied in the electronic equipment, described electronic equipment is the electronic equipments such as personal computer, server, and described electric supply installation 100 comprises: power input interface 101, power output interface 102, stand-by power supply 103, detection module 104 and handover module 105.
Wherein, described power input interface 101 is used for being connected with commercial power supply module 200.Described commercial power supply module 200 typically refers to mains power socket, and described power input interface 101 is connected with described commercial power supply module 200 by attaching plug.
Described power output interface 102 is used for being connected the devices such as the mainboard that described current-collecting device 300 is described electronic equipment, display with the current-collecting device 300 of described electronic equipment.
Whether described detection module 104 is normal for detection of the power supply of described power input interface 101, and exports a testing result.Whether described detection module 104 can fluctuation occur by the voltage that detects power input interface 101 inputs or whether stop the voltage input, and whether the power supply that detects described power input interface 101 is normal.
Described power input interface 101 be connected stand-by power supply 103 and all be connected with described power output interface 102 by described handover module 105, described handover module 105 is used for when the testing result of described detection module 104 represents the power supply abnormal of described power input interface 101, disconnect described power input interface 101 and be connected the connection of power output interface 102, and connect described stand-by power supply 103 and described power output interface 102.
After connecting described stand-by power supply 103 and described power output interface 102, described stand-by power supply 103 provides non-firm power by described power output interface 102 for the current-collecting device 300 in the described electronic equipment, with when power failure or voltage fluctuation appear in civil power, ensure the data security of electronic equipment and the hardware damage of avoiding electronic equipment.
