Integration computer power-off protection power supply
Technical field
The present invention relates to a kind of integration computer power-off protection power supply.
Background technology
At present, commonly used UPS uninterrupted power source carries out power-off protection to computer, and UPS uninterrupted power source needs to pass through Serial ports or USB interface are connected with computer, and need system program and computer to carry out communication, and a lot of computer is taken Be loaded with different types of system, it may appear that the situation that UPS uninterrupted power source is not compatible with computer system, and UPS not between Power-off source can only keep the power supply of certain time in the event of a power failure and shut down, and cannot automatically turn on meter after restoring electricity Calculation machine.The general volume ratio of UPS uninterrupted power source is relatively big, takes up room relatively big, and cost is high.
Summary of the invention
For solving above technical deficiency, the invention provides the collection that a kind of volume is little, effective to guard of computer Accepted way of doing sth computer circuit breaking protection power supply.
The present invention is achieved by the following measures:
A kind of integration computer power-off protection power supply of the present invention, including being integrated in a circuit board
On switch power module, DC-ATX power module and Time delay circuit and external accumulator;Described open The voltage output end closing power module is connected with DC-ATX power module voltage input end, DC-ATX power module voltage output end Connect and have computer motherboard interface;Described accumulator is connected in parallel on switch power module voltage output end and DC-ATX power module electricity Between pressure input, and between the voltage output end positive pole of battery positive voltage and switch power module, it is connected to diode VD1, institute State diode VD1 by the voltage output end positive pole of switch power module to battery positive voltage one-way conduction;
Described Time delay circuit includes that the time-delay relay being connected in parallel on switch power module voltage output end and triggering are closed Closing branch road, the instantaneous contacts of described time-delay relay is parallel with relay normally open contact K2, relay normally open contact K2 and calculating Machine activate switch is in parallel, and described triggering in Guan Bi branch road is in series with diode VD2, relay normally closed switch K1 and relay coil K2, described diode VD2 are by the voltage output end of switch power module positive voltage directional relay normally closed switch K1 one-way conduction, relay It is parallel with electric capacity C2, relay coil K1 after the series connection of device normally closed switch K1 and relay coil K2 and is connected to switch power module Between voltage output end both positive and negative polarity.
Above-mentioned relay coil K1 is in series with diode VD3, described diode VD3 and is exported by the voltage of switch power module Rectifying voltage directional relay coil K1 one-way conduction, relay coil K1 is parallel with electric capacity C1.
The invention has the beneficial effects as follows: volume is little and is desirably integrated into device interior, and can be the most automatic Shut down computer, after restoring electricity, automatically turn on computer, it is possible to effectively protection computer system and data.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the present invention.
Wherein: 1 Switching Power Supply, 2DC-ATX power module, 3 time-delay relays, 4 accumulator, 5 computer motherboard interfaces.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is done further detailed description:
As it is shown in figure 1, a kind of integration computer power-off protection power supply of the present invention, including integrated
Switching Power Supply 1 module, DC-ATX power module 2 and Time delay circuit on a circuit board and external The accumulator 4 of 12V.Exchange 90-220v is turned 14.8v by Switching Power Supply 1 module.The voltage output end of Switching Power Supply 1 module and DC- ATX power module 2 voltage input end connects, and DC-ATX power module 2 voltage output end connects computer motherboard interface 5;Store Battery 4 is connected in parallel between Switching Power Supply 1 module voltage outfan and DC-ATX power module 2 voltage input end, and accumulator 4 Being connected to diode VD1 between the voltage output end positive pole of positive pole and Switching Power Supply 1 module, described diode VD1 is by Switching Power Supply 1 The voltage output end positive pole of module is to accumulator 4 positive pole one-way conduction;
Time delay circuit includes the time-delay relay 3 being connected in parallel on Switching Power Supply 1 module voltage outfan and triggers Guan Bi Branch road, the instantaneous contacts of time-delay relay 3 is parallel with relay normally open contact K2, relay normally open contact K2 and computer starting Switch in parallel, is in series with diode VD2, relay normally closed switch K1 and relay coil K2, institute in described triggering Guan Bi branch road Stating diode VD2 by the voltage output end positive voltage directional relay normally closed switch K1 one-way conduction of Switching Power Supply 1 module, relay is normal It is parallel with electric capacity C2, relay coil K1 after the series connection of make and break pass K1 and relay coil K2 and is connected to Switching Power Supply 1 module electricity Between pressure output positive and negative charge.If needing delay switching-off, relay coil K1 series diode VD3, diode VD3 is by switching The voltage output end positive pole of power supply 1 module is parallel with electric capacity C1 to relay coil K1 one-way conduction, relay coil K1.Time delay Relay 3 uses FUJI ST3 model.
Its operation principle is: during normal power supply work, and input 90-240v exchange becomes direct current through Switching Power Supply 1 module 14.8v, returns DC-ATX power module 2 by diode VD1 to the battery charging of 12V, 7A simultaneously powers, DC-ATX power supply mould 2 14.8V direct currents of block become three groups of voltages 12V, 5V, 3.3V of computer motherboard interface 5.Computer normally works.Use DC- ATX power module 2 substantially increases direct current supply efficiency.
When, after electricity power-off, accumulator 4 continues as computer power supply, due to the one-way conduction of diode VD1
Effect, relay coil K1 power-off, due to the one-way conduction effect of diode VD3, storage originally has the electricity of electric energy Hold C1 only to discharge to relay coil K1, there will be the discharge lag of several seconds, relay coil according to the parameter size of electric capacity C1 K1 obtains electric, and relay normally closed switch K1 closes, and due to the one-way conduction effect of diode VD2, storage originally has the electric capacity of electric energy C2 only discharges to relay coil K2, relay normally open contact K2 moment close after disconnect, due to relay normally open contact K2 and Computer starting switch in parallel, is equivalent to export the time delay on-off model of several seconds and switchs to computer starting, calculate Machine is according to former setting automatic shutdown.
When recovering civil power, relay coil K1 obtains electric, and relay normally closed switch K1 disconnects, whole tactile
Send out delay circuit not work, and be only through time-delay relay 3 and obtain electric, the instantaneous contacts wink of time-delay relay 3 Between disconnect after Guan Bi, be equivalent to export the time delay on-off model of several seconds and switch to computer starting, computer according to Former setting Auto Power On.
The above is only the preferred implementation of this patent, it is noted that for the ordinary skill people of the art For Yuan, on the premise of without departing from the art of this patent principle, it is also possible to make some improvement and replacement, these improve and replace Also should be regarded as the protection domain of this patent.
