Abstract

A fingerprint recognizer is added on a normal keyboard, namely, a sampling window of the fingerprint identification module is arranged on a keyboard. An optical type fingerprint identification module or others types fingerprint identification modules are arranged inside the keyboard. Not only a GL 602 or others chips as the main control IC of the keyboard, but also a fingerprint identification module is arranged inside the keyboard. The optical type fingerprint identification module is adopted in the embodiments of the utility model, and a GL 650 chip and others same function chips are used as the main control IC of the function part of the HUB; as shown in the figure, a sampling window for the fingerprint identification(6), a fingerprint identification module(5), a USB interface(3), a peripheral of the keyboard(8), a main control IC of the keyboard (7) and a USB interface(4) are connected with the computer through the main control IC(2) of the HUB and the USB interface(1), as a result, the corresponding functions are realized.

Description

A kind of fingerprint recognition keyboard

Technical field

The utility model relates generally to a kind of keyboard that has fingerprint identification function.

Background technology

Keyboard function ratio commonly used is more single, and more existing Multi-Function Keyboards, fingerprint identification function often the peripheral hardware by computer or keyboard independently fingerprint debate and know product and realize complicated operation; And the utility model adopts integrated design, and fingerprint recognition system has ensured the safety of system as confirming user's identity and determining whether start-up system or other restricted operations by computer.

Summary of the invention

The purpose of this utility model provides a kind of keyboard that has fingerprint identification function, effectively promotes computer system safety, and is easy and simple to handle.

In order to address the above problem, the technical solution adopted in the utility model is: in keyboard, except that being provided with GL602 or other chips as the keyboard master control IC, also be provided with fingerprint identification module, in the utility model embodiment, adopt the optical fingerprint identification module, simultaneously, with GL650 chip or other congenerous chips master control IC as HUB (referring to the HUB integrated circuit (IC) chip, as follows) funtion part; Shown in figure one, fingerprint recognition sampling window (6), fingerprint identification module (5), USB interface (3), keyboard peripheral hardware (8), keyboard master control IC (7), USB interface (4) all connect computer, thereby realize its corresponding function by HUB master control IC (2), USB interface (1).

The fingerprint identification function part comprises that mainly fingerprint recognition sampling window (6), fingerprint identification module (5), USB interface (3), HUB funtion part mainly are by its master control IC (2) and peripheral cell R4, R5, R9, R11, R12, R25-29, C5, C6, C15, Y3 etc. are together, shown in figure two, connect, an output USB interface (1) is expanded to two USB interface (3), (4).The HUB main control part is fixed on the main circuit board on the mouse internal backplane with the keyboard main control part, fingerprint module is fixed on the base plate of keyboard, be connected to main circuit board by the multiway winding displacement, connect computer by USB interface (3), HUB master control IC (2), USB interface (1) again.

When fingerprint recognition sampling window (6) is collected user's fingerprint signal, and when sending fingerprint identification module (5) to, fingerprint identification module carries out analyzing and processing to its signal message, send computer to by USB interface (3), HUB master control IC (2), USB interface (1), the software that matches in the computer carries out analyzing and processing identification to signal, determining whether it is safe handling person, open system function or carry out other restricted operations whether.

Keypad function partly adopts current techique.

The utility model has been realized the multifunctional all of fingerprint recognition and keypad function by the improvement of its structure and technology, easy and simple to handle, powerful, high safety, plug and play.

Description of drawings

Fig. 1 is the utility model circuit block diagram;

Fig. 2 the utility model schematic appearance;

Fig. 3 is the circuit diagram of the utility model HUB part.

Embodiment

Shown in figure one, be circuit theory synoptic diagram of the present utility model, HUB part is mainly by the USB interface that is connected with computer (1), form as the HUB master control IC (2) of master control IC, the USB interface (3) that is connected with fingerprint identification module (5), the USB interface (4) that is connected with keyboard master control IC (7) with the GL650 chip; USB interface (1) is passed through with HUB master control IC (2), the peripheral cell R4 of GL650 chip as master control IC, R5, R9, R11, R12, R25-29, C5, C6, C15, Y3 etc. expand to USB interface (3), (4) with a USB interface (1) together, and then realize that a plurality of functional modules all are connected with computer by same USB interface (1); Fingerprint identification function partly comprises fingerprint recognition sampling window (6), fingerprint identification module (5), USB interface (3), when the user by fingerprint recognition sampling window (6) when finger print information is provided, fingerprint identification module (5) is handled its information, send computer to by USB interface (3), HUB master control IC (2), USB interface (1), the software that matches in the computer carries out analyzing and processing identification to signal, determining whether it is safe handling person, open system function or carry out other restricted operations whether.

Shown in figure two, be the utility model schematic appearance, (6) are pointed to and are the fingerprint sampling window.

Shown in figure three, be HUB partial circuit figure of the present utility model, with the HUB master control IC (2) of GL650 chip as its master control IC, with the element R4 of periphery, R5, R9, R11, R12, R25-29, C5, C6, C15, Y3 etc. expand to USB interface (3), (4) with a USB interface (1) together jointly, and then realize that a plurality of functional modules all are connected with computer by same USB interface (1); FB1, FB2, FB3, FB4, C1, C2, C7, C10 play anti-interference effect for the power filter element.

Claims

1, a kind of fingerprint recognition keyboard is characterized in that: set up fingerprint identification device on the common keyboard, the fingerprint identification module sampling window promptly is set on the keyboard, keyboard is provided with optical profile type or other types fingerprint identification module.

2, a kind of fingerprint recognition keyboard shown in claim 1, it is characterized in that: refer to promptly that by HUB the USB output interface that HUB chip functions part will be connected with computer expands to two USB interface in keyboard, respectively as keypad function partly, the output interface of fingerprint identification module.
