An intelligent power control device

Abstract

Disclosed in the invention is an intelligent power supply controlling apparatus comprising a communication circuit, a single-chip microcomputer control circuit, a relay driving circuit, a relay output array, a power output unit, a power supply converting circuit and a filter circuit. The single-chip microcomputer control circuit is connected with the communication circuit; a first output terminal of the single-chip microcomputer control circuit is connected to a first input terminal of the relay driving circuit; an output terminal of the relay driving circuit is connected to a first input terminal of the relay output array; and an output terminal of the relay output array is connected to an input terminal of the power output unit. According to the invention, with the relay output array, a power supply of an equipment host and peripheral components can be turned off completely when timing shutdown is realized remotely. On the one hand, the electric energy is saved, the equipment aging process slows down, and the equipment service life is prolonged; and on the other hand, a phenomenon that the equipment host and peripheral components after shutdown are struck by thunder can be prevented, so that the equipment can be protected effectively. The apparatus can be widely applied to self-service terminal equipment.

Description

Technical field [0001] The invention relates to the technical field of power supply control, in particular to an intelligent power supply control device. Background technique [0002] With the wide application of various self-service terminal equipment (such as self-service teller machines, self-service ticket machines, self-service inquiry machines, self-service charging machines, etc.) in the market, when the business is over, when the equipment is not needed, in order to achieve the purpose of energy saving and maintenance of the equipment, The equipment needs to be turned off; when the equipment needs to be used at the beginning of the business, the equipment needs to be turned on. For some business outlets, such as subway stations, bank outlets, etc., due to the large number of equipment and the timing and switching time of each equipment is not the same, manual operation is obviously a waste of manpower and material resources. Therefore, more methods currently used are: se...

Problems solved by technology

The disadvantage of this method is: after the device is turned off, the network card of the device host is still in the state of charged standby, and the power supply is not completely turned off. Although the energy consumption is reduced, long-term charged standby will accelerate the aging of the device and reduce the life

There is a hidden danger in this method: when the device is powered on or powered off, some high-power components will generate a large inrush current, which will cause impact damage to the device host and some low-power components
