Abstract
The program controlled steps are as following: booting up computer; system reads information of BIOS in main board; screen displays control interface; inputting password; system validates the password; activating the control board to unlock electromagnetic lock. Circuit structure of the control board is as following: being connected to COM interface of main board, the interface of control board sends lock controlled information on the screen interface to data processor MCU; based on lock controlled information to control electromagnetic switch to output current; electrified electromagnetic lock attracts dead bolt to open up chassis lock; opening cover of chassis. When pushing the close button on the screen control interface, then based on lock controlled information, MCU controls electromagnetic switch to close down current; winding of electromagnetic lock is deenergized; dead bolt is ejected by the reset spring so as to lock the chassis. Features are: simple structure, easy of use, and high safety.
Description
1, technical field
The present invention relates to a kind of computer cabinet safe antitheft technology, specifically a kind of computer cabinet with cipher code magnetic control lock.
2, background technology
Along with development of computer and universal; increasing user is extensive use of computing machine; the computer cabinet of prior art all is to adopt the casing that can directly dismantle, without any safeguard measure; anyone can both open this cabinet; so cause the equipment of cabinet inside stolen easily, thereby the deficiency that exists is that security performance is low; at present, good solution is not also arranged.
3, summary of the invention
The purpose of this invention is to provide a kind of computer cabinet with cipher code magnetic control lock.The open and close of electromagnetic lock are by the user the unpacking password of computer operating system input to be realized.
The computer cabinet of band cipher code magnetic control lock of the present invention, program control step is: open computing machine, system reads mainboard BIOS information, screen display control interface, input password, system validation password activate control panel and open electromagnetic lock; The circuit structure of control panel is: the control panel interface is connected with the com interface of mainboard, to send data processor MCU to handle from the lock control information on the screen interface, according to lock control information Control electromagnetic switch output current, the electromagnetic lock coil gets electric adhesive dead bolt Machine case lock is opened, chassis lid is opened, and X button is pressed at same function screen control interface, and processor MCU is turned off electric current according to lock control information Control electromagnetic switch, the electromagnetic lock coil losing electricity, dead bolt is ejected the cabinet locking by back-moving spring.
The cabinet of charged magnetic padlock of the present invention is compared with prior art, box body and chassis lid lock together by electromagnetic lock, the user has only unlatching and the locking that could control magnetic control lock by the password of unpacking to the operation system of computer input, behind the input password, can open after the machine system identification as calculated, so have very high security, also have characteristics such as performance height simple in structure, easy to use, safe simultaneously, have good value for applications.

Description of reference numerals: mainboard 1; Box body 2; Electromagnetic lock 3; Chassis lid 4; Plug connector 5.
5, embodiment
Below in conjunction with accompanying drawing the cabinet of charged magnetic padlock of the present invention is done following detailed explanation.
As shown in Figure 1, charged magnetic padlock of the present invention is to be made of chassis lid 1, box body 2, electromagnetic lock 3, mainboard 1, all have the hole slot of mutual correspondence on the side that chassis lid 4 and box body 2 join, electromagnetic lock 3 is fixed on the box body 2, the dead bolt of electromagnetic lock 3 be through box body 2 and chassis lid 4 corresponding mutually hole slot in, the power lead connector 5 on being arranged on computer motherboard 1 that connects electromagnetic lock 3 is plugged on.The open and close of electromagnetic lock 3 are by the user the unpacking password of computer operating system input to be realized.
Embodiment:
When needs repair or replace computer-internal hardware, open computing machine, system reads mainboard BIOS information, screen display control interface, input password, system validation password activate control panel and open electromagnetic lock; The circuit structure of control panel is: the control panel interface is connected with the com interface of mainboard, to send data processor MCU to handle from the lock control information on the screen interface, according to lock control information Control electromagnetic switch output current, the electromagnetic lock coil gets electric adhesive dead bolt Machine case lock is opened, and chassis lid is opened.Dang Ji Xu machine enclosure internal hardware maintenance or change finish after, start computing machine, after system works is normal, X button is pressed at function screen control interface, processor MCU is turned off electric current according to lock control information Control electromagnetic switch, the electromagnetic lock coil losing electricity, and dead bolt is ejected the cabinet locking by back-moving spring.
