Abstract
The utility model discloses a Chinese second generation ID (identity) card verification device free from USB (universal serial bus) drive. An internal circuit comprises a USB interface, a microcontroller, a USB drive-free module, a serial port channel switching circuit and a serial communication interface. The microcontroller is connected with the serial port channel switching circuit through an input and output interface of the microcontroller, one port of the serial port channel switching circuit is connected with the serial communication interface, the other port of the serial port channel switching circuit is connected with the USB interface through the USB drive-free module, the microcontroller adopts a system type MCU (microprocessor control unit) on a completely integrated low-power-consumption mixed signal chip, and the USB drive-free module adopts a GTCTRL2.0 module. The utility model has the beneficial effects that no USB drive programs needed, the device is suitable for reading of USB devices through non-Windows platforms which do not support USB interfaces, in particular for Chinese second generation ID card verification devices.
Description
Technical field
The utility model relates to the China second-generation identity card verification equipment that a kind of USB of exempting from drives.
Background technology
The data-interface of on-line second generation ID card reader generally is divided into serial ports and two kinds of ports of USB, when using USB port, the USB driver of the encryption and decryption module SAM that a state security department provides must be installed on PC earlier, PC could be discerned this USB device after installing this driver, and reads second generation resident identification card internal information by usb protocol.
Along with the develop rapidly of computer hardware technology, USB port becomes the multi-purpose computer port, and serial ports becomes the apolegamy port gradually, so the on-line second generation resident identification card card reader of USB type is used in increasing occasion.But the equipment such as card reader of USB port type also have its shortcoming, be exactly that corresponding SAM module drive must be installed, but now state security department only provides the USB under the WINDOWS system of this module to drive, the special unit higher as the bank to the data safety requirements, usually adopt the terminating machine of linux system, on this Terminal Type machine new driver can't be installed, can't use Certification of Second Generation card reader, therefore require card reader manufacturer to develop a kind of on-line card reader that USB drives that need not to install based on the Universal USB interface.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of second generation ID card verification equipment that USB drives that need not to install is provided.
The purpose of this utility model is achieved through the following technical solutions: exempt from the China second-generation identity card verification equipment that USB drives, its internal circuit comprises USB interface, microcontroller, USB free drive module, serial ports channel switching circuit and serial communication interface, microcontroller is connected with the serial ports channel switching circuit by its IO interface, a port of serial ports channel switching circuit connects serial communication interface, and another port is connected with USB interface by USB free drive module.
Microcontroller described in the utility model is fully-integrated low-power consumption mixed signal SOC (system on a chip) type MCU.
USB free drive module described in the utility model is the GTCTRL2.0 module, and the packaged type in the USB free drive module is the encapsulation of 10 pin stamp pass pads, and its inside also is provided with one 32 8-digit microcontroller.
The beneficial effects of the utility model are to have realized a kind of China second-generation identity card verification equipment that still need not to install the USB driver on non-Windows operating system.
Description of drawings
Fig. 1 is modular structure figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail: as shown in Figure 1, exempt from the China second-generation identity card verification equipment that USB drives, its internal circuit comprises USB interface, microcontroller, USB free drive module, serial ports channel switching circuit and serial communication interface, microcontroller is connected with the serial ports channel switching circuit by its IO interface, a port of serial ports channel switching circuit connects serial communication interface, another port is connected with USB interface by USB free drive module, under the situation about needing one or more usb hub Hub can also be set at the USB interface place, thereby be converted to a USB interface a plurality of and a plurality of interfaces are used simultaneously.
The HID agreement is adopted in the USB communication transmission of the China second-generation identity card verification equipment of USB interface, the agree as follows of HID agreement: the iProduct territory in the device description is " XXXXXXYYYYY_Ver ZZZZZZ_IDCardReader Device ", and wherein XXXXX is that manufacturer, YYYYY are that equipment batch, VerZZZZZZ are firmware version in the equipment; BInterfaceSubClass territory in the interface descriptor is 0x00; Version is V1.11.
GetReport request transmission is adopted in the input of HID data, and SetReport request transmission is adopted in the output of HID data, and this host-host protocol only defines the data field in GetReport and the SetReport order, i.e. message.The input of HID data is all adopted the subpackage mode with output, and the data length of single bag is fixed as 64 bytes, and less than 64 bytes are then filled with 0x00; After the outgoing message fractionation, end packet curtailment 64 bytes are then filled with 0x00.
The single-chip microcomputer that microcontroller adopts is C8051F410/1/2/3, and this chip is fully-integrated low-power consumption mixed signal SOC (system on a chip) type MCU, and this chip main performance is as follows:
(1) at a high speed the microcontroller of 8051 compatibilities of pipeline organization (can reach 50MIPS);
(2) at full speed the on-line system debugging interface of non-intrusion type;
(3) the 24.5Mhz internal oscillator of high-precision programmable.
The microcontroller that high-speed secure and precision are high has guaranteed to exempt from China second-generation identity card verification equipment that USB drives can be at a high speed, safety and verify and discern second generation I.D. accurately.
USB free drive module realizes the conversion of serial data and USB_HID agreement, this module adopts the GTCTRL2.0 module, its inner 10 pin stamp pass pads that adopt encapsulate, and embed one 32 8-digit microcontroller, the serial ports of realizing the Card Reader data by software receives, and the Card Reader data are converted to USB_HID agreement and PC or computer terminal communication.
The function of serial ports channel switching circuit is to carry out communication between the data encryption SAM module of selecting to adopt on serial communication mode or moving communication modes of USB free drive and the main frame.
