Description

Computer power source supply device

Technical field

The present invention relates to a kind of power system, especially a kind of computer power source supply device, have rechargeable reserve battery and startup and wake await orders computer special use (ATX the is compatible) power supply unit of controlling signal of (Suspend to RAM) program and auto sleep (Auto-Suspend to Disk) program of power saving up for a kind of, during if it receive abnormal outage signal, can send signal immediately and start the STR program of waking up or the auto sleep program of establishing in the computer, arrive in hard disc or the CD-RW discsCD-RW with the data storage that will be temporarily stored in storer or the I/O, again shutdown automatically.

Background technology

The computer power source supply device of known tool ups system has two kinds, as Fig. 4 and shown in Figure 5, the power system that Fig. 4 directly provides computer system (and peripheral equipment) 42 to use for a kind of ATX of belonging to computer power source special supply 41, and at this system front end AC power supplies input end uninterrupted power supply (ups) Unity 4 in parallel, then can change when AC power supplies is cut off the power supply by uninterrupted power source 4 provides ATX computer power source special supply 41 standby AC power supplies, works as machine to prevent computer because of undesired outage.Fig. 5 is a kind of power system that is connected with the uninterrupted power supply (ups) Unity 44 of one group of tool Auto-STD function between ATX computer power source special supply 41 and computer system (and peripheral equipment) 42, this system can provide the DC standby power supply to use preventing that computer from working as machine to computer system (and peripheral equipment) 42 by uninterrupted power supply (ups) Unity 44 when AC power supplies is cut off the power supply, and can utilize the UPS internal control signal to start the auto sleep system.

In above-mentioned two kinds of known power systems, ATX computer power source special supply 41 with all belong to the kenel that two members separate setting at its front end or uninterrupted power supply (ups) Unity 43,44 that the rear end was connected, therefore it can be created in the disappearance of structure and space requirement increase, and increases the manufacturing cost of host computer; These uninterrupted power supply (ups) Unitys are for saving the demand in cost and space again, it is little that its power supply amount that can provide is provided, the time that can provide computer to use after promptly having a power failure is not long, only can after the civil power outage, continue to be engaged in the storage of some data or do last emergency work such as arrangement, and the utilization rate that adds uninterrupted power supply (ups) Unity is not high, and the standard of non-computer is equipped with, so be not widely used.Moreover, if fully when not installing uninterrupted power supply (ups) Unity,, then can't retrieve the just information in operation, the then disappearance that easily causes data loss and repeat to key in fully if meet the situation of undesired outage; Therefore the power system of general known computer special use has necessity of improvement more in fact.

Summary of the invention

For overcoming problem and the disappearance that above-mentioned known computer power source supply system can produce when its actual use, special computer power source supply device of the present invention proposed.

Fundamental purpose of the present invention is providing a kind of computer power source supply device, it has the rechargeable stand-by circuit of interchange (AC) outage, and have the controlling signal circuit of the STR program of waking up and auto sleep (Auto-STD) program of ATX series concurrently, and can be when undesired outage takes place AC power supplies, wake computer or startup auto sleep (Auto-STD) program immediately up, so that the data in storer or the I/O is preserved for a long time in battery saving mode armed state (Suspend to RAM).

Of the present invention time a purpose is providing a kind of computer power source supply device, and it wakes the controlling signal structure of STR program and auto sleep program up with rechargeable stand-by circuit and startup, and can reduce constructions cost and simplify space requirement.

Another purpose of the present invention is providing a kind of computer power source supply device, and it can send caution cresset and auditory tone cues user when carrying out auto sleep (Auto-STD) program.

A further object of the present invention is providing a kind of computer power source supply device, its can be when improper outage with the data storage in storer or the I/O in hard disc, behind telegram in reply, can allow computer be returned to duty before the outage again, and can shorten the switching on and shutting down time of computer.

For reaching above-mentioned purpose, computer power source supply device of the present invention, mainly at one group of ac-dc converter circuit and rechargeable stand-by circuit, be connected with a control circuit on the DC power circuit, wherein, ac-dc converter circuit with can provide rechargeable stand-by circuit respectively after the city is electrically connected, control circuit and DC power circuit use, and it is used to offer the DC power circuit through the change-over switch that control circuit is controlled in the stored electric power of rechargeable stand-by circuit, have simultaneously in this control circuit again and start the auto sleep program and wake the await orders controlling signal circuit of (STR) program of power saving up, send a telegraph brain when working or under the power saving armed state, receive the outage signal, can borrow rechargeable stand-by circuit to provide standby power supply to carry out STR or the dormancy program (STD) waken up, will dumping in hard disc or the CD-RW discsCD-RW in the data among storer or the I/O, and this computer shutdown automatically after definite data storage is finished; And when next alternating current is sent a telegram in reply, can allow computer be returned to the preceding duty of outage.

Computer power source supply device of the present invention, its advantage is as follows:

1. the present invention starts the controlling signal of auto sleep (Auto-STD) program immediately when undesired outage takes place AC power supplies, automatically the data storage in storer and the I/O being preserved to hard disc (HDD) or CD-RW discsCD-RW (CD-ROM).

2. it can will be in the computer of battery saving mode armed state (as Suspend to RAM) when undesired outage takes place AC power supplies, can send the controlling signal of waking power saving standby (STR) program up, restart auto sleep (Auto-STD) program to wake computer earlier up, with file maintenance.

3. it can simplify the demand and the standard of general UPS structure, and can reduce constructions cost and simplify space requirement after having merged ATXPS (PowerSupply).

4. it can send caution cresset and sound and know with the prompting user when carry out startup auto sleep (Auto-STD) program.

5. it can strengthen the power management of existing windows system (WINDOWS), makes it shorten the switching on and shutting down time.
