Abstract
The invention provides a low-power consumption stand-by circuit and a stand-by control method, wherein the low-power consumption stand-by circuit comprises a primary power supply and a secondary power supply, wherein the primary power supply is mutually connected with a stand-by circuit of an electric appliance, and the secondary power supply is further connected with the power part of the electric appliance except mutually connecting with the stand-by circuit of the electric appliance. The invention adopts the primary power supply to supply electricity for the stand-by circuit, the secondary power supply restores to work when signals are detected (such as a power supply key is pressed, signal input is detected and the like), and systems normally work. The low-power consumption stand-by circuit can lower system power consumption, and satisfies the requirements of saving energy and lowering consumption.
Description
(1) technical field
What the present invention relates to is that a kind of electronic equipment is treated machine technology, particularly a kind of machine technology for the treatment of that satisfies electronic equipment standby needs in the productive life with lower power consumption.
(2) background technology
The standby power of general commonly used electronic equipment all adopts to be told one road 5VDC from total power supply (Switching Power Supply for the 220VAC access commonly used) system control chip is powered, and its basic circuit structure as shown in Figure 1.System is when standby (comprising dormancy, soft-off) state, and the equipment master is consumed energy and partly quit work, but each control chip still is in work (or low-power consumption work) state, and the certain power demand is arranged, and this moment, 5VDC still offered system's groundwork power supply.
Electric current when surveying the standby of 17 cun LCD of certain model and soft-off is about 23mA, and then the actual power loss of this display under this state is approximately 5W.If electrical equipment is equipment such as computer host box or TV, this numerical value will bigger, and this power consumption will be very big, so need improve this technology.
(3) summary of the invention
The object of the present invention is to provide and a kind ofly can reduce system power dissipation, satisfy the low-power consumption standby circuit and the standby controlling method of energy-saving and cost-reducing demand.
The object of the present invention is achieved like this:
The composition of low-power consumption standby technology of the present invention comprises primary power source and secondary power supply, and the stand-by circuit of primary power source and electric equipment is interconnected, secondary power supply is gone back connecting circuit equipment except that interconnected with the stand-by circuit of electric equipment power section.
Low-power consumption standby method of the present invention is:
(1) electric power system adopts primary power source and secondary power supply secondary supply power mode;
(2) stand-by circuit adopts the primary power source power supply when standby/soft-off;
(3) when holding state recovers, enable secondary power supply when system, close primary power source;
(4) with secondary power supply complete machine is powered;
Enable primary power source when (5) system transfers standby/soft-off state to, close secondary power supply.
The invention provides a kind of new machine technology for the treatment of, refer to a kind ofly especially,, break through traditional disposable supply power mode design limitation whereby, reduce system power dissipation, satisfy energy-saving and cost-reducing demand to reach the purpose of system's power supply by the secondary supply power mode about electronic equipment.
The present invention adopts primary power source that stand-by circuit is powered, and when detecting signal (as press power key, detect signal input etc.), recovers secondary power supply work, system's operate as normal.
Beneficial effect of the present invention is that power consumption of the present invention greatly reduces than a power supply circuits power consumption commonly used.When being located at the display employing secondary supply power mode of mentioning in the background technology, the primary power source circuit adopts capacitance decompression, output current is 30mA, voltage is 5V, consider the loss of step-down process, then primary power source counterpart total power consumption should be about 0.2W, and then stand-by power consumption has reduced approximately 96%, and it is then more that mainframe box reduces.Though single circuit has only reduced about 4.8W, consider the extensive use background of this circuit, the energy-saving effect of its generation is very considerable.Be exemplified below: unofficial statistics's data in 2006 show that Chinese computer owning amount is 1.2 hundred million, and by annual 35% speed increase, then by 2008 the end of the year China will have 2.2 hundred million computers.With 200,000,000 computers, reduce power consumption 10W during every standby (soft-off), every 8 hours standby every day (soft-off) time, China 58.4 hundred million kWh that can economize on electricity every year then, be equivalent to 51.7% of in August, 2008 Three Gorges plant generator peak period energy output, the energy output that is equivalent to 2,340,000 tons of standard coals reduces 5,300,000 tons of CO2 emissions, 1.4 ten thousand tons of sulfur dioxide, 2.7 ten thousand tons of nitrogen oxide, and can save 5,800,000 tons the spent water resources of mine coal; Consider that there are idle function in relevant family expenses such as TV, air-conditioning, printer, office in a large number with equipment, so this numerical value is absolute conservative estimation.

Fig. 1 is the electrical block diagram of prior art;
Fig. 2 is an electrical block diagram of the present invention;
Fig. 3 and Fig. 4 are the circuit structure diagrams of two kinds of embodiments of the present invention.
(5) embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 2, the composition based on the low-power consumption standby technology of the present invention comprises primary power source and secondary power supply, and the stand-by circuit of primary power source and electric equipment is interconnected, secondary power supply is gone back connecting circuit equipment except that interconnected with the stand-by circuit of electric equipment power section.
The invention relates to the innovation of a kind of electronic equipment standby (soft-off) technology, its control timing is as follows:
(1) electric power system adopts the secondary supply power mode;
(2) stand-by circuit adopts the primary power source power supply when standby (soft-off);
(3) when holding state recovers, enable secondary power supply when system, close primary power source;
(4) with secondary power supply complete machine is powered;
Enable primary power source when (5) system transfers standby (soft-off) state to, close secondary power supply.
Also can be still when recovering the work of secondary electric power system with primary power source to the power supply separately of stand-by circuit part, but consider that device power consumption when work such as CPU can significantly increase, so need increase primary power source electric current fan-out capability, power consumption increases to some extent in the time of will causing standby.
The exemplary embodiment of the low-power consumption standby technology of its PC mainframe box as shown in Figure 3, Figure 4, miscellaneous equipment can be with reference to design.
Fig. 3 for standby with simple low-power consumption primary power source, be output as 5VDC, 100mA.
Adopt primary power source power supply shown in Figure 3 during standby, when system need be from standby (soft-off) recovering state, control relay recovers the power supply of ATX power supply, then 5VDC is switched on the 5VDC of ATX power supply, the power supply input that provides the ATX enabling signal at last and cut off primary power source can be finished standby (soft-off) start-up course.When system transfers standby (soft-off) state to by operating state, said process carried out conversely getting final product.
By above-mentioned steps, can reach the purpose of the given low-power consumption standby of the present invention.
