Abstract
The utility model relates to an integrated universal serial bus interface equipment, which mainly comprises a USB hub, a USB transceiver module, a single chip microcomputer, a fingerprint sampler, an IC card reader-writer, a radiofrequency card reader, an LCD liquid crystal display screen, a keyboard and so on. The fingerprint sampler with a USB interface is directly connected with a computer through the USB hub; while other components such as the keyboard, the liquid crystal display screen, the IC card reader-writer and the radiofrequency card reader are controlled by the single chip microcomputer, and then are connected with the computer through the USB transceiver module as well as the USB hub, and exchange information and accept control. Compared with the prior art, the utility model has the advantages that the integration level is very high; the Microsoft HID (human interface device) standards are adopted to realize no driving, so the installation and the using are convenient; and the interfaces are unified to decrease the error probability of the system.
Description
Technical field:
The utility model relates to a kind of integrated form USB (USB (universal serial bus)) interface arrangement that uses with computer interconnection
Background technology:
In the electronic device and equipment of prior USB (USB (universal serial bus)) interface, as the common inline process type finger-print recognising instrument in market, all need a plurality of members such as integrated acquisition component (fingerprint capturer, radio-frequency card and IC-card card reader etc.), LCD LCDs, numeral and function keyboard usually.Prior art fails to realize integrated management and the control to these members, management and control to these members are all carried out respectively, for example, power devices adopts external power supply, to computer, and LCD liquid crystal display and Keyboard Control are to finish by the serial communication interface of computer to the transmission of the signal of acquisition component by USB interface and cable.Like this, the input of drawing from these equipment, output cable minimum more than two.Make troubles to the user in actual use, and the possibility that causes system to make a mistake increases.
Summary of the invention:
Goal of the invention of the present utility model be to provide a kind of integrated level very high, adopt the HID of Microsoft (human interface device) standard free drive reason and easy to install, and unified and USB (USB (universal serial bus)) interfacing equipment that system's error probability is reduced of interface.
The utility model is to realize like this.It mainly is made of usb hub, USB transceiver module, single-chip microcomputer, fingerprint capturer, IC-card read write line, radio-frequency card reader, LCD LCDs and keyboard etc., the fingerprint capturer of USB interface directly is connected with computer by usb hub, other members such as keyboard, LCDs, IC-card read write line, radio-frequency card reader then pass through Single-chip Controlling, commentaries on classics is by the USB transceiver module, also be connected to computer then, exchange message and accept control by usb hub.
Single-chip microcomputer is as control center of the present utility model, links to each other with computer with usb hub by the USB transceiver module.All keyboard inputs are all handled by USB notice PC computer with event mode.Equipment is when receiving order that the PC computer sends or data, handle by Single-chip Controlling, display graphics or literal on LCDs LCD, also can play the voice that record in advance by voice module, to the process and the result of order and operation, can also send the acousto-optic indication by Single-chip Controlling.
The utility model compared with the prior art, owing to adopted the design of high integration, unified interface, and adopted HID (human interface device) standard of Microsoft, simultaneously Overall Power Consumption has been carried out strict control in design, thereby make the utility model can realize many outstanding advantages: unique interface (USB interface, both as communication interface, be again the power supply input), the installation that the free drive flowing mode brings and easy-to-use, and the integrated design of multiple member comprehensively satisfying to many application systems.
Description of drawings:
Fig. 1 is a structure block diagram of the present utility model;
Fig. 2 is single-chip microcomputer of the present utility model, usb hub, USB transceiver module circuit diagram;
Fig. 3 is integrated component circuit diagrams such as voice module of the present utility model.
Among Fig. 2, Fig. 31, usb hub; 2, USB transceiver module; 3 single-chip microcomputers; 4, LCD LCDs interface; 5, keyboard interface; 6, voice module; 7, the first-class acquisition component interface of fingerprint; 8, acousto-optic indication interface; 9, IC read write line, radio-frequency card reader interfaces; 10, electric light is isolated input/output interface.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model mainly is made of usb hub, USB transceiver module, single-chip microcomputer, LCD LCDs, keyboard, voice module, fingerprint capturer, IC-card read write line, radio-frequency card reader, electric light isolation I/O.Fingerprint capturer directly is connected with computer by usb hub; Other all members all are connected with single-chip microcomputer respectively, by single-chip microcomputer unified management and control, through the USB transceiver module, are connected with computer by usb hub 1 again.
In actual the use, the utility model can cooperate many application software to carry out work, finishes major functions such as the automatic identification of personal identification.During work, equipment is connected to the USB interface of computer by the USB cable, and equipment obtains power supply from USB interface immediately behind the launch computer.Computer operation application software is sent information to equipment, is presented at the LCD LCDs or the control voice module sends voice suggestion through Single-chip Controlling, and the prompting user carries out associative operation.Such as, the fingerprint capturer input fingerprint of prompting user slave unit, be sent to and carry out fingerprint authentication in the computer, according to the checking result, on the single-chip microcomputer that sends back for information about in the equipment, on LCD, show or change relevant information by Single-chip Controlling, control the voice module prompting (result or the further prompting of operation) of sounding simultaneously, control LED display lamp correspondence bright, put out.Similar process, computer software also can be by Single-chip Controlling IC-card read write line or the radio-frequency card reader in the equipment, finish the IC-card that the user is held and the read-write of radio-frequency card content, and in this read-write process, provide multiple operation and results suggest such as LCD demonstration, voice, led color light.
In the utility model, multiple acquisition modes such as fingerprint capturer, IC-card read write line and radio-frequency card reader can also exist and collaborative work simultaneously.Fingerprint template such as the user can leave in earlier in the IC-card (as social insurance card), when needing checking holder identity, insert IC-card, computer reads in the fingerprint template of storage in advance from IC-card, and then the prompting user imports same fingerprint on fingerprint capturer, and both are compared, draw checking result go forward side by side line correlation operation and results suggest.
