Abstract
The utility model discloses a computer power failure protection system which consists of an uninterrupted power supply (UPS) and an intelligent protection circuit, wherein the input end of the UPS is connected with mains supply, and the output end of the UPS supplies power to a protected computer; the intelligent protection circuit comprises a central processing unit (CPU), a transformer, a diode, a capacitor and two resistors, wherein the input end of the transformer is connected with the mains supply; an output voltage signal is sequentially connected with the P0.0 port of the CPU through the diode and a first resistor; the second resistor is connected in parallel with the capacitor, and one end of the second resistor is grounded; the other end of the second resistor is connected between the diode and the first resistor; and the CPU is connected with the protected computer through a communication interface. The power is supplied to the computer by utilizing the UPS, and the power of computer is prevented from being suddenly cut off; according to the intelligent protection circuit, when the mains supply fails, the computer is powered off after files which is being edited is saved, so that the loss of the files and text data is effectively avoided, and the safety of the hard disk of the computer is protected.
Description
Technical field
The utility model relates to a kind ofly can start back-up source automatically when the computing machine sudden power, and makes that computing machine files automatically, shutdown automatically, guarantees the device of hard disk secure, belongs to field of computer technology.
Background technology
Computing machine is in the course of the work during sudden power; File, the text information do not preserved as yet will be lost, and hard disc of computer also might come to harm, therefore; Some computing machine has been equipped with ups power (uninterrupted power source); When catastrophic discontinuityfailure appears in civil power, be computer power supply automatically, and send alerting signal, remind the staff in time to file and shut down computer.If but the staff fails shutdown in time for some reason when catastrophic discontinuityfailure appears in civil power, after the electric weight of treating the battery storage in the ups power exhausted, computing machine still can cut off the power supply, and the file of not depositing, text information and hard disc of computer still can be on the hazard.
The utility model content
The purpose of the utility model be to overcome prior art deficiency, provide a kind of and can when catastrophic discontinuityfailure appears in civil power, start back-up source automatically, and make that computing machine files automatically, the computer circuit breaking protection system of shutdown automatically.
The alleged problem of the utility model realizes with following technical proposals:
A kind of computer circuit breaking protection system; Be made up of ups power and intelligent protection circuit, the input termination civil power of said ups power, output terminal are given by the protection computer power supply; Said intelligent protection circuit comprises CPU, transformer, diode, electric capacity, first resistance and second resistance; The input termination civil power of said transformer, the voltage signal of its output connect the P0.0 port of CPU successively through diode and first resistance, second resistance and the electric capacity back one end ground connection that is connected in parallel; One is terminated between the diode and first resistance, and said CPU is connected with being protected computing machine through communication interface.
Aforementioned calculation tester in power-down state protection system, the communication interface of said CPU adopts USB interface.
The utility model utilizes ups power to be computer power supply, prevents the computing machine sudden power.Simultaneously, intelligent protection circuit detects the power supply situation of civil power in real time, when civil power breaks down; CPU exports control signal to computing machine; Shut down behind the file that computing machine is kept editing, thereby effectively avoided losing of file, text information, protected the safety of hard disc of computer.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to detail.
Fig. 1 is the outside drawing of the utility model;
Fig. 2 is the electrical schematic diagram of the utility model.
Each label is among the figure: 1, city's plug; 2, shell; 3, computing machine jack; 4, signal transmssion line; 5, USB plug; UPS, uninterrupted power source; CPU, microprocessor; PT, transformer; D, diode; R1, R2, resistance; C, electric capacity; USB, interface chip.
Embodiment
Referring to Fig. 1, ups power of the utility model and intelligent protection circuit all are installed in the shell 2, and shell 2 outer setting have city's plug 1, computing machine jack 3 and USB plug 5.City's plug 1 is plugged on the commercial power socket, and the power-line plug of computing machine is plugged in the computing machine jack 3, and USB plug 5 is plugged in the USB jack of computing machine.
Referring to Fig. 2, transformer PT is connected on the input end of ups power, and whether be used to detect civil power normal.When civil power just often, the ac voltage signal of transformer PT output is delivered to the P0.0 port of CPU again through first resistance R 1 after diode D rectification, capacitor C filtering, this moment, the P0.0 port of CPU was a high level; When civil power broke down, ups power was worked automatically, for computing machine provides continual power supply, sent alerting signal simultaneously.Transformer PT no signal output this moment, capacitor C makes the P0.0 port of CPU become low level by high level through 2 discharges of second resistance R.After the high level that CPU detects its P0.0 port becomes low level,, shut down behind the file that computing machine is kept editing through USB interface output control signal.The so-called machine control signal that closes is actually one group of shutdown programm instruction, and computing machine will be deposited rapidly and shut down after receiving instruction, thereby has avoided information dropout.
Claims (2)
1. computer circuit breaking protection system; It is made up of ups power and intelligent protection circuit; The input termination civil power of said ups power, output terminal are given by the protection computer power supply, it is characterized in that; Said intelligent protection circuit comprises CPU, transformer (PT), diode (D), electric capacity (C), first resistance (R1) and second resistance (R2); The input termination civil power of said transformer (PT), the voltage signal of its output connect the P0.0 port of CPU successively through diode (D) and first resistance (R1), second resistance (R2) and electric capacity (C) the back one end ground connection that is connected in parallel; One is terminated at the negative electrode of diode (D), and said CPU is connected with being protected computing machine through communication interface.
