Description of drawings

The present invention will be further described below in combination with specific embodiments with reference to the accompanying drawings.

Fig. 1 is the functional block diagram of the preferred embodiment of the computer case with IC card identification function of the present invention.

Detailed ways

Please refer to Fig. 1, the preferred embodiment of the computer case 100 of the present invention tool IC (Integrated circuit, integrated circuit) card recognition function comprises a case body (not shown) that is used to install computer host computer, described case case body An IC card reader 10 is arranged on the top, and a microcontroller 20 , a data storage unit 30 , a power switch control unit 40 and a lock control unit 50 are arranged inside.

The IC card reader 10 is connected to the data storage unit 30 through the microcontroller 20 , and the power switch control unit 40 and the lock control unit 50 are connected to the microcontroller 20 . The data storage unit 30 stores specific data information set by the user for the computer case 100 . In this embodiment, the power switch control unit 40 includes a first relay and a power switch, the first relay is used to control the on-off of the power switch, and the power switch is used to connect the The starting power supply of the computer mainframe in the box; the lock control unit includes a second relay and a lock, the lock is used to lock the side panel of the chassis box, and the second relay is used to control the opening of the lock with off.

After the computer mainframe is installed inside the chassis body, an IC card internally stores data information matching the internal data of the data storage unit 30, and the lock is in a closed state before the computer mainframe is connected to a power supply. After the host computer is connected to the power supply, if you need to use the host computer, just scan the IC card in front of the IC card reader 10, and the microcontroller 20 receives the IC card The data information on the card is matched and compared with the data information of the data storage unit 30. When the two data information match each other, the microcontroller 20 is controlled by the first relay of the power switch control unit 40 The power switch is turned on, that is, the computer host is started; at the same time, the microcontroller 20 controls the lock to be opened through the second relay, and the side panel of the computer case can be opened, so that the user can maintain or upgrade . After the main computer power supply is turned on and the chassis casing is in an openable state, if the user wants to close the computer mainframe and lock the casing casing, as long as the IC card is scanned again before the IC card reader 10, At this time, the IC card reader 10 receives the data information of the IC card again and the received data information is matched and compared with the data information of the data storage unit 30 by the microcontroller 20 again. , when the two data information match, the microcontroller 20 controls the power switch to be turned off through the first relay of the power switch control unit 40, that is, the computer host is turned off, and the microcontroller 20 is turned off through the The second relay of the lock control unit 50 controls the lock to be closed, and the side panel of the computer case is locked, so as to prevent non-computer administrators from maliciously opening it.

In this embodiment, the IC card reader 10 adopts a dual power supply mode, that is, it supplies power when the power supply of the computer host is normal; when the computer host fails, the IC card reader 10 The internal battery supplies power to facilitate the maintenance of the host computer. The battery is generally a rechargeable battery. When the power supply of the host computer is normal, the rechargeable battery is charged by the power supply of the host computer. The computer case 100 with IC card identification function can effectively protect users' computers, and is especially suitable for managing multiple computers in public places.
