Description
Technical field
The present invention relates to field of computer technology, particularly with the computing machine of power failure protection module.
Background technology
According to statistics, all 45% of computer glitches cause by power issue.Main cause is the civil power instability, and there are the much electricity quality problems in it, for example power failure, thunderbolt spike, surge, frequency oscillation, voltage jump, voltage fluctuation, frequency drift, electric voltage dropping, impulse disturbances etc.These quality problems can cause bad phenomenon such as the keyboard lockout, hardware aging of computing machine, also may cause data to be lost fully or mainboard such as burns at major accident.
In the prior art, the power-off protection scheme that computing machine is commonly used generally all is to adopt UPS.UPS is a kind of energy storage device that contains, and is main element with the inverter, the power protective equipment of voltage stabilization and frequency stabilization output.But the problem of using UPS to exist is: strict to environment temperature; Need regularly discharge and recharge; There is the acid mist leakage phenomenon.Therefore, need carry out regular maintenance to UPS, to prolong its serviceable life, reduce the generation of fault, this has increased the maintenance cost of computing machine undoubtedly.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of computing machine with power failure protection module.It can reduce the failure rate of computing machine and guarantee that user data do not lose, and has that cost is low, the characteristics of long service life.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of computing machine with power failure protection module, it comprises power module and the computer motherboard that connects successively.Power module comprises current rectifying and wave filtering circuit and the DC-DC translation circuit that links to each other with civil power.Its design feature is that described power module also comprises by the control circuit that is connected in series successively, charging circuit, farad level storage capacitor, discharge circuit power failure protection module of forming and the cut-offing alarming circuit that links to each other with the DC-DC translation circuit.The output of described current rectifying and wave filtering circuit is connected respectively to DC-DC translation circuit and power failure protection module, and the output of power failure protection module is connected to the DC-DC translation circuit.
In the aforementioned calculation machine, described charging circuit is composed in series by first diode and first resistance, and described discharge circuit is composed in series by second diode and second resistance.
In the aforementioned calculation machine, the withstand voltage of described farad level storage capacitor is 450V.
The present invention is incorporated into power failure protection module in the power module owing to adopted said structure, and computer hardware and user data just can effectively be protected in the space that need not enlarge computer host box, for computer system provides high-quality power supply.Power failure protection module cost among the present invention is low, charging rate is fast, energy conversion rate is high, safety non-pollution, can use for a long time non-maintaining.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the prior art constructions synoptic diagram;
Fig. 2 is the structural representation of power module among the present invention;
Fig. 3 is the connection diagram of power failure protection module in power module among the present invention.
Embodiment
Referring to Fig. 1 to Fig. 3, the present invention includes the power module and the computer motherboard that connect successively.Power module comprises the current rectifying and wave filtering circuit that links to each other with civil power, DC-DC translation circuit, be the power failure protection module formed of farad level storage capacitor 1 and the discharge circuit of 450V and the cut-offing alarming circuit that links to each other with the DC-DC translation circuit by the control circuit that is connected in series successively, charging circuit, withstand voltage.The output of current rectifying and wave filtering circuit is connected respectively to DC-DC translation circuit and power failure protection module, and the output of power failure protection module is connected to the DC-DC translation circuit.Charging circuit is composed in series by first diode 4 and first resistance 5, and discharge circuit is composed in series by second diode 2 and second resistance 3.
When the present invention normally provided the 220V alternating voltage by civil power, civil power provided stable 300V DC voltage to the DC-DC translation circuit through current rectifying and wave filtering circuit.By the DC-DC translation circuit produce that computer motherboard needs ± 12V ,+DC voltage of 5V and 3.3V.Simultaneously, the farad level storage capacitor 1 in the power failure protection module is charged through current rectifying and wave filtering circuit by civil power.During under-voltage or sudden power, the buzzer warning prompting user civil power in the warning circuit disconnects when civil power.Simultaneously, the control circuit in the power failure protection module sends control signal, makes farad level storage capacitor 1 provide electric energy through discharge circuit to the DC-DC translation circuit, and to guarantee the operate as normal of computing machine, the user can preserve data during this period and turn off computer.
