Anti-false triggering method and DC power supply device applying the same

The invention relates to an anti-false triggering method and a DC power supply device using the same, in particular to an anti-false triggering method with a power saving mechanism and a DC power supply device.

Portable devices, such as cell phones, tablets, personal digital assisters (PDAs) or notebook computers (NB), have become one of the everyday items of modern people. The portable device uses a DC power supply as a source of electrical energy.

At present, most of the portable devices are shipped separately from the DC power supply unit. However, the specific models of a few system factories require DC power supply devices to be shipped on the body, so some DC power supply devices are available. The function of the ship mode/shipping mode. A control unit sends a specific command to the register of the DC power supply device to enter the transportation power saving mechanism. After entering the transportation power saving mechanism, the DC power supply device will be powered off and no longer supply power. This ensures that when the user gets the portable device, The DC power supply unit can also retain a certain amount of power. The way to release the power saving mechanism is to restore the normality by charging the DC power supply.

However, if the DC power supply device manufacturer enters the transportation power saving mechanism after the DC power supply device enters the power supply device, the DC power supply device is accidentally connected to the power supply before the DC power supply device is packaged, or the DC power supply device is connected to the DC power supply device. After the portable device is inadvertently connected to the power supply, the DC power supply device will leave the transportation power saving mechanism. Therefore, when the user obtains the portable device, it is possible that the power of the DC power supply device has been exhausted.

The invention discloses an anti-false triggering method and a DC power supply device using the same. With the anti-false triggering method of the present invention, the DC power supply device manufacturer can set the battery to the transportation power saving mechanism.
