It can be understood that, in china, the commercial power is 220V ac, the first power supply is dc, and the first conversion module 100 converts 220V ac into dc.
The self-service device power supply device 10 provided by this embodiment is provided with a first power supply, a second power supply, a power management module 210, a power failure detection module 110, a main control module 300 and a power failure processing module 310, when the main control module 300 receives a power failure signal, the main control module 300 controls the power management module 210 to switch the self-service device from the first power supply to the second power supply according to the power failure signal, and meanwhile, the main control module 300 transmits the power failure signal to the power failure processing module 310, and the power failure processing module 310 performs power failure processing on the host 20 to control the host 20 to store current data and prepare for shutdown.

In one embodiment, as shown in fig. 3, the self-service device power supply apparatus 10 further includes a second conversion module 120, and in the case that the self-service device is powered by the first power supply, the second conversion module 120 converts the first power supply into a first power supply voltage and a second power supply voltage, the first power supply voltage is used for supplying power to the host 20 of the self-service device, and the second power supply voltage is used for supplying power to the peripheral 30 of the self-service device. In case the second power supply supplies power to the self-service device, the second conversion module 120 converts the first power supply into a third power supply voltage and a fourth power supply voltage, the third power supply voltage is used for supplying power to the host 20 of the self-service device, and the fourth power supply voltage is used for supplying power to the peripheral 30 of the self-service device. The second conversion module 120 includes a DC-DC converter, where DC represents direct current, and the DC-DC converter is a device for converting one direct current voltage into another direct current voltage. It will be appreciated that the host 20 and the peripheral 30 of the self-service device require different dc supply voltages, and the second conversion module 120 converts the dc voltage to different dc supply voltages to power the host 20 and the peripheral 30, respectively. The self-service device power supply apparatus 10 in this embodiment can simultaneously supply power to the host 20 and the peripheral 30 of the self-service device.
It will be appreciated that when the self-service device is fed with mains power, outputting a voltage for powering the host 20 and a voltage for powering the peripheral 30, in the case where the mains power is normally used to power the self-service device, the first power supply provides power to both the host 20 and the peripheral 30 of the self-service device. Meanwhile, the battery 200 may be charged by the commercial power through the power management module 210. When a power-down signal is detected, the battery 200 management module switches the power supply of the self-service device to be powered by the first power supply and the second power supply, namely the battery 200. Wherein the battery 200 may be a lead acid battery or a lithium battery. Of course, in some other embodiments, the battery 200 may be replaced by a farad capacitor.

The first conversion module 100, the battery 200, the power management module 210 and the power failure detection module 110 are integrated together, the structure is simple, the integration level is high, the problems that when the mains voltage is unstable or the power failure occurs suddenly, the data of the self-service equipment is lost and damaged can be avoided by switching between the first power supply and the second power supply, and the data storage and backup of the self-service equipment are facilitated.
In one embodiment, as shown in fig. 5, the first conversion module 100 and the power down detection module 110 can be integrated together as the second power supply unit 50 of the self-service device, so that the switching between the first power supply and the second power supply is performed in a power management module 210 external to the second power supply unit 50. The cost of the self-service device power supply 10 is reduced by not integrating the power management module 210 within the second power supply unit 50.
It will be appreciated that the first power supply unit 40 differs from the second power supply unit 50 in that the power management module 210 is integrated with the first power supply unit 40, and the second power supply unit 50 does not have the power management module 210 integrated, so that the first power supply unit 40 or the second power supply unit 50 can be flexibly and selectively installed on some self-service device power supply apparatuses 10.
For example, self-service device power supplies are used on ATM machines. At present, some ATMs are installed in bank outlets, and all the bank outlets are equipped with an Uninterruptible Power Supply (UPS), which is a constant voltage and constant frequency UPS that includes an energy storage device and an inverter as a main component. The device is mainly used for providing uninterrupted power supply for a single computer, a computer network system or other power electronic equipment. When the mains supply input is normal, the UPS supplies the mains supply to a load for use after stabilizing the voltage of the mains supply, and the UPS is an alternating current mains supply voltage stabilizer and also charges an energy storage component in the machine; when the commercial power is interrupted (power failure in accident), the UPS immediately supplies 220V alternating current to the load by the electric energy of the built-in energy storage component through an inversion conversion method, so that the load keeps normal work and protects the software and hardware of the load from being damaged. Therefore, at a bank outlet where the UPS is installed, the second power supply unit 50 is installed only on the ATM, and the power management module 210 does not need to be integrated inside the power supply unit. When the voltage value output by the first power supply is smaller than the preset voltage value, outputting a power-down signal; the main control module 300 informs the UPS according to the power failure signal, and the UPS immediately supplies the 220V ac power to the first conversion module 100 by using the inversion conversion method.
