Abstract
The utility model relates to a filing cabinet with switch on-off controlled by a computer. The filing cabinet comprises the computer and the filing cabinet and is characterized in that the filing cabinet is fixedly connected with a switch control circuit module, wherein the switch control circuit module comprises an electromagnetic relay, a singlechip and a switch; the singlechip is connected with the electromagnetic relay through the switch; a USB (universal Serial Bus) interface is arranged on the filing cabinet, is connected with the switch control circuit module and is also connected with a USB interface of the computer through a data cable; the USB interface of the computer is connected with a CPU (Central Processing Unit) of the computer; and a storage is connected between the USB interface of the computer and the CPU of the computer in parallel. The filing cabinet has the benefits that a use mode of locking and unlocking by manual operation in a traditional filing cabinet is changed; and a connecting relationship is established between the filing cabinet and the computer. The filing cabinet can be used for better ensuring the security of information and is convenient for office process to use.
Description
Technical field
The utility model belongs to file cabinet, relates in particular to a kind of file cabinet through the computer gauge tap.
Background technology
The lockset of traditional file cabinet is made up of pure mechanical part, unblanks by accomplishing manually, the function of locking.When the staff leaves under the own seat situation for a long time,, just be easy to cause vital document or data to lose if the staff does not in time lock to self-administered file cabinet.The documents cabinet accounts for critical role at work, and is independently individual between the computer of office indispensability and the file cabinet always.Change the occupation mode of traditional file cabinet, between file cabinet and computer, establish a connection.Not only better guarantee the safety of data, and make things convenient for office process to use.
The utility model content
The utility model is in order to overcome deficiency of the prior art, and a kind of file cabinet through the computer gauge tap is provided, and computer is gauge tap directly, and opening or closing of realization computer control documents cabinet ensured the safety of capsule information and file.
The utility model is realized through following technical scheme for realizing above-mentioned purpose, a kind of file cabinet through the computer gauge tap; Comprise computer and file cabinet; It is characterized in that: said file cabinet is connected with the ON-OFF control circuit module, and said ON-OFF control circuit module is by electromagnetic relay, and single-chip microcomputer and switch constitute; Said single-chip microcomputer is connected with electromagnetic relay through switch; Said file cabinet is provided with USB interface, and said USB interface is connected with the ON-OFF control circuit module, and USB interface is connected with the USB interface of computer through data wire; The USB interface of computer links to each other with the CPU of computer, parallel memory between the USB interface of said computer and the CPU of computer.
Said memory is the memory of eight hexadecimal data sections of address bit storage.
Beneficial effect: change traditional file cabinet is accomplished manually and is unblanked, the occupation mode of locking, between file cabinet and computer, establishes a connection.Not only better guarantee the safety of data, and make things convenient for office process to use.

The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that provides according to the utility model: see accompanying drawing for details, a kind of file cabinet through the computer gauge tap; Comprise computer 1 and file cabinet 2; Said file cabinet is connected with ON-OFF control circuit module 6, and said ON-OFF control circuit module is by electromagnetic relay, and single-chip microcomputer and switch constitute; Said single-chip microcomputer is connected with electromagnetic relay 5 through switch; Said file cabinet is provided with USB interface 3, and said USB interface is connected with the ON-OFF control circuit module, and USB interface is connected with the USB interface of computer through data wire 4; The USB interface of computer links to each other with the CPU of computer, is parallel with the memory in specific eight hexadecimal data sections of address bit storage between the USB interface of said computer and the CPU of computer.
Memory in the computer circuits module (Eeprom) is used for can being referred to as " UC data " in specific eight hexadecimal data sections of address bit storage.USB interface is used for and being connected of external equipment, and links to each other with the CPU of computer, is used to judge whether computer is in open state, if be in the normal boot-strap state, then smoothly output through USB interface output 5V voltage, otherwise output low level is a 0V voltage.
The single-chip microcomputer of file cabinet circuit module; When obtaining the 5V power supply, begin to read " the UC data " in the assigned address among the computer end Eeprom, and judge whether to mate, if detect information matching with " the UC data " of file cabinet through the usb data line; Then controlling the switch ways that is attached thereto opens; Make 5V voltage flow into the electromagnetic relay of lower end, this moment, relay was started working, and file cabinet is opened.Otherwise file cabinet can be in closed condition always.
Operation principle
Based on the exportable 5V voltage of computer USB interface, the voltage that the electromagnetic relay on the file cabinet is carried through the USB cable is judged the folding of switch.And then realization is unblanked, blocking function.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
Claims (2)
