Description

The adapter of China second-generation identity card reader

Technical field

The utility model relates to a kind of accessories apparatus of electronic recognition technology, especially a kind of adapter that is used for the China second-generation identity card reader.

Background technology

Present financial industry, especially bank all need to show identity document when handling some the deposit or the withdrawal, and by bank clerk ID (identity number) card No. are manually imported computer.Along with popularizing of second generation I.D., because the built-in contactless IC chip that contains certificate information of second generation I.D., new the false proof of I.D. mainly reads to form with machine-readable two parts by looking, and looks and reads partly can with the naked eye distinguish the true and false, and machine-readable part then need be discerned by machine.Had the machine-readable reader of many moneys second generation I.D. on the market, read the certificate information in the IC chip in the I.D. by radio frequency chip, give the computer terminal by serial ports or USB mouth with information transmission, and numerical information is reduced into image or character by the terminal software that is installed on computer, on the window of computer terminal, show, to distinguish the certificate true and false, false proof degree is very high.

Certainly, reader is used in restriction and the shortcoming that himself is also arranged in these particular environment of bank and other financial mechanism.Because security needs, financial industry PC terminals such as bank mostly adopt DOS, Unix system, and the windows terminal software can't be installed, and except PS2 keyboard mouth, do not have unnecessary RS232 or USB mouth to connect identity card reader.If the machine-readable certificate true and false of distinguishing must dispose a computer that terminal software is housed in addition and realize this reading task.So not only increase equipment drops into budget, and uses and extremely inconvenient.

The utility model content

The purpose of the present utility model: be intended to propose a kind of adapter that is applicable to that the China second-generation identity card reader uses, make the existing terminal computer of present financial circles utilization just can conveniently understand the built-in information of China second-generation identity card ideally, reach the purpose that improves industry work efficiency, minimizing equipment input.

This China second-generation identity card reader adapter is characterized in that: described adapter 1 has one and has PS simultaneously ₂Male 1-1, again a PS arranged ₂The connecting line 1-3 of female 1-2, and pass through PS ₂Male 1-1 inserts PS ₂The output terminal that connects the PC terminal.

Described is that adapter comprises a MCU chip 1-4, MAX232 chip 1-5, with E2PROM chip 1-6, described MCU chip 1-4 respectively with E2PROM chip 1-6, composition group information memory, form serial port circuit with MAX232 chip 1-5 and be connected with 2 of China second-generation identity card readers; Simultaneously, this MCU chip 1-4 also is respectively equipped with interface and links to each other with computer terminal 4 with input keyboard 3.

The adapter of this China second-generation identity card reader that proposes according to above technical scheme is passed to computer by conversion with data, and entry information possesses and reached following some beneficial effect.

1. adapter has become the PC terminal can discern the PS2 mouth protocol data that receives second generation ID (identity number) card information data-switching, has realized the coupling between data;

The operation of 2 adapter simulating keyboards is transferred to the PC terminal with certificate information, has realized the transmission between data;

3. make the user use the setting software that provides to change the corresponding setting option easily, just can set the sequential time-delay of keyboard operation etc. arbitrarily according to actual conditions;

4. adapter takies the PS of PC terminal ₂The keyboard mouth, the input data provide a PS simultaneously ₂Female mouthful is connected with original keyboard, the operation of reception keyboard, and intactly issue computer, the normal utilization of guarantee keyboard.

5. adapter by prior setting, is differentiated key by catching the keyboard key, and the output relevant information; The user can set up arbitrary button (or Macintosh) on their own and export each (or multinomial) certificate information, and is easy and simple to handle, and can accomplish to apply in a flexible way:

6. adapter adds the function of preserving configuration information, even outage can not destroy original configuration information yet, and will read in automatically after powering on, and only need be once convenient for users to use to the setting operation of adapter;

7. adapter is directly sent to the PC terminal with certificate information by changing, for the user has saved expense at terminal development and installing terminal software; Adapter takies the original PS2 mouth of PC terminal, need not to increase in addition other connector, has saved the expense that additional interface is installed.

Description of drawings

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is formed structural representation for adapter.

Embodiment

This China second-generation identity card reader adapter shown in accompanying drawing 1,2 is made of physical construction and electronic structure two parts, it is characterized in that: described adapter 1 has one and has PS simultaneously ₂Male 1-1, again a PS arranged ₂The connecting line 1-3 of female 1-2, and pass through PS ₂Male 1-1 inserts PS ₂The output terminal that connects the PC terminal is formed the physical construction part.

Described electronic structure partly is that adapter comprises MCU chip 1-4, a MAX232 chip 1-5 and E2PROM chip 1-6; MCU chip 1-4 wherein respectively with E2PROM chip 1-6, composition group information memory, form serial port circuit with MAX232 chip 1-5 and be connected with 2 of China second-generation identity card readers; Simultaneously, this MCU chip 1-4 also is respectively equipped with interface and links to each other with computer terminal 4 with input keyboard 3.Like this, not only use the original PS2 mouth of PC terminal, need not to increase extra interface, do not hinder the use of original keyboard again.

Aspect electronic technology, the principle and the scheme that are provided are as follows: adapter is preserved the certificate information of reading from reader, and receives the key set code that keyboard sends, compare with prior setting, if consistent with the button of setting, will send the corresponding certificate information of button to PC so, pass through PS ₂The operation of mouth simulating keyboard, the input method input information different according to the user; If button is different with setting, then this keypad code is remained untouched and issue terminal, so just guaranteed the operate as normal of original keyboard.The MCU chip is by serial ports (Transistor-Transistor Logic level changes into the level that meets the serial ports standard through the MAX232 chip)) read the certificate information of reading from reader, and the key set code of reception keyboard transmission, compare with prior setting, if it is consistent with the button of setting, to send the corresponding certificate information of button to PC so, pass through PS ₂The operation of mouth simulating keyboard, the input method input information different according to the user; If button is different with setting, then this keypad code is remained untouched and issue terminal, so just guaranteed the operate as normal of original keyboard.Can preserve data after the outage of E2PROM chip, so prior configuration information is preserved wherein, the back MCU that at every turn powers on takes out configuration information automatically from E2PROM, and finishes initialization.
