Abstract
The utility model relates to a power-supplying system for a complete machine, particularly to a power-supplying control device for each unit of a complete machine. The utility model discloses a distribution type power-supplying apparatus. The utility model has the technical scheme that the distribution type power-supplying apparatus comprises a power supply circuit, an interface circuit and an element circuit. The utility model is characterized in that the utility model also comprises a control circuit. The power supply circuit is connected with the element circuit by the control circuit which is connected with the interface circuit, and the element circuit is a DVI/HDMI demoding circuit. The utility model has the advantages that the power supplies of relevant element circuits are cut off automatically under the condition of no signals, which reduces the power consumption of the complete machine and prolongs the service life of the complete machine.
Description
Technical field
The utility model relates to the complete machine electric supply system, particularly each unit power supply control apparatus of complete machine.
Background technology
Television set is to the development of multi-functional aspect.Various signal interface circuits and decoding circuit are introduced in the television set in a large number, and DVI, HDMI interface promptly are typical case's representatives wherein.DVI, HDMI interfacing are two kinds of high bandwidth uncompressed digital video interfacings of at present tool market potential, have had 50% high-grade display and digital television receiver to adopt DVI or HDMI interface as the digital video input interface at present.No matter be DVI or HDMI interface or other interfaces, only after signal source work, receiving terminal just can carry out corresponding signal process work.In the prior art, no matter whether interface circuit is in running order, as long as complete machine is started working, each correlation unit circuit promptly is in "on" position, both wastes energy, and also can shorten machine life.
The utility model content
Technical problem to be solved in the utility model is exactly big at the energy resource consumption of prior art complete machine, and the shortcoming that the life-span is short provides a kind of device according to each interface signal source operating state control correlation unit power supply.
The utility model solve the technical problem, and the technical scheme of employing is that the distributed power supply device comprises power circuit, interface circuit and element circuit; It is characterized in that: also comprise control circuit; Described power circuit is connected with element circuit by control circuit; Described control circuit is connected with interface circuit;
Described element circuit is the DVI/HDMI decoding circuit;
Described control circuit comprises testing circuit and power switch; Described testing circuit is connected with interface circuit and power switch; Described power switch is connected with element circuit with power circuit respectively.
The beneficial effects of the utility model are, automatically the correlation unit circuit power are turn-offed under the no signal situation, have reduced Overall Power Consumption, prolong complete machine useful life.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is the structural representation of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model is by detecting the signal of interface circuit, and the operating state of determining unit circuit according to the operating state of signal source, is controlled the power supply of correlation unit circuit, thereby reached energy saving purposes
The technical solution of the utility model is that the distributed power supply device comprises power circuit, interface circuit and element circuit; It is characterized in that: also comprise control circuit; Described power circuit is connected with element circuit by control circuit; Described control circuit is connected with interface circuit;
Described element circuit is the DVI/HDMI decoding circuit;
Described control circuit comprises testing circuit and power switch; Described testing circuit is connected with interface circuit and power switch; Described power switch is connected with element circuit with power circuit respectively.
Fig. 1 shows structural representation of the present utility model.Among the figure, the output of power circuit is connected to element circuit by control circuit, and control circuit is connected with interface circuit.When the signal source connection, when element circuit was in running order, the interface circuit output signal was to control circuit, and the control circuit energized is for element circuit provides operating voltage.
Embodiment
This routine element circuit is the DVI/HDMI decoding circuit.Apparatus structure is seen Fig. 2.According to the difference of complete machine operating state, divide two parts to describe:
1, inserts the DVI/HDMI signal during complete machine operate as normal.This moment, HP-DET (hot-swappable detection) signal of signal source output was connected to testing circuit by the DVI/HDMI physical interface, and testing circuit output control signal drives the power switch conducting, and power circuit is switched on.+ 5V ,+3.3V ,+the 1.8V circuit is exported associated voltage respectively, is that the DVI/HDMI decoding circuit is powered.Simultaneously, the complete machine video shows that treatment circuit and audio frequency processing circuit are connected to the DVI/HDMI decoding circuit; Can carry out normal audio frequency and video after signal source and complete machine are finished communicating by letter of necessity plays.
Insert the DVI/HDMI signal when 2, complete machine is in holding state.At this moment, signal source transmits the CEC signal to complete machine CPU, and CPU opens the complete machine power supply and brings into operation.HP-DET (hot-swappable detection) signal of signal source output is connected to testing circuit by the DVI/HDMI physical interface, and testing circuit output control signal drives the power switch conducting, and power circuit is switched on.+ 5V ,+3.3V ,+the 1.8V circuit is exported associated voltage respectively, is that the DVI/HDMI decoding circuit is powered.Simultaneously, the complete machine video shows that treatment circuit and audio frequency processing circuit are connected to the DVI/HDMI decoding circuit; Can carry out normal audio frequency and video after signal source and complete machine are finished communicating by letter of necessity plays.
