Description
Technical field
The invention belongs to the design field of computer hardware equipment, be specifically related to a kind of computer peripheral equipment connection device that can be used to read smart card novel, that have high-speed interface by high speed interfaces such as USB or SD/MMC.
Background technology
Existing built-in peripheral hardware connection device is a lot of at present for computing machine, as USB interface, and SD card, 1394 interfaces etc.These interfaces can organically link together computing machine with different consumer electronics products, play effects such as function control to these electronic products, data access, content update.Also improved simultaneously the arithmetic capability of computing machine greatly and to the control ability of independent peripheral equipment.
Smart card (Smart Card) is embedded in integrated circuit (IC) chip in the plastic substrate, is packaged into the form of card.The smart card of main flow has limited data storage and processing power at present.Be mainly used in different application fields such as storage, logical encrypt or the processing of realization certain calculation.Traditional contact intelligent card has eight contacts, carries out the information transmission by the interface and the card reader that meet ISO/IEC 7816 consensus standards.Have in its eight contacts five (power supply,, reset, clock and data) clearly definition in the ISO/IEC7816 agreement.Remaining three contact is not formally definition as yet, still has the leeway of function expansion.The SIM card of using in the mobile phone handsets just belongs to a kind of of smart card.SIM card also is subjected to the constraint of the standards such as GSM11.11 of ETSI except that meeting ISO/IEC 7816 standards.Its clock frequency is generally worked between the 5MHz at 1MHz, and the transfer rate of data is usually below 150K bps.The highlyest be no more than 600K bps.During the memory capacity at smart card smaller (tens K byte magnitudes), this message transmission rate has been enough.
High-speed interface in computing machine, such as USB, more much higher than the speed of SIM interface.The speed that USB1.1 can provide is at 12M bps, and the available message transmission rate of USB2.0 more can be up to 480M bps.And the SD/MMC interface also can provide the message transmission rate more than 25M bps.This high-speed interface is more suitable for the timely transmission in mass data.
In the recent period because the mobile phone technology rapid development has also proposed new requirement to the SIM card that is equipped with.Be mainly reflected in lifting, along with the raising of memory capacity and computing power, its interface rate with the external world also had corresponding raising in addition its memory capacity and arithmetic capability.Some SIM card with high-speed interface is in trial sale in the market, and what its high-speed interface adopted mainly is USB or SD/MMC interface.
For traditional SIM card that the ISO/IEC7816 interface is only arranged, because its arithmetic capability and storage capacity are not high, interface arrangement by special use, high-speed interface device particularly, the demand that card is linked to each other with computing machine is not outstanding, therefore a small amount of breakout box that constitutes by ISO/IEC 7816 agreements and usb protocol conversion chip is only arranged on the market, SIM card is linked to each other with computing machine, come to link to each other with smart card by the conversion between ISO/IEC 7816 agreements and the usb protocol, realize the data in the SIM card being carried out access by computing machine with the USB mouth of computing machine.This breakout box in fact only is a protocol converter, with SIM card interface one side, what still adopt is ISO/IEC 7816 protocol ports, is not the directly card reader by USB port operative intelligence card truly.Because the rate limit of ISO/IEC 7816 interfaces, this device can not really utilize the high speed characteristics of high-speed interface that the data on the card are carried out access.Along with the increase of the data storage capacity on the SIM card, to carry out the requirement of zero access (more than per second ten megabits) just urgent day by day to blocking data by high-speed interface.With a concrete example, a operation, if with ISO/IEC 7816 card reader of flank speed with SIM card of 512M bit capacity, being 600k bps reads, need spend 853 seconds, this is for the user, and this stand-by period is an acceptable hardly.And adopt 12M bps USB interface, only need about 43 seconds time.
But so far, go back neither one easily the computer peripheral equipment connection device directly utilize the high speed characteristics access smartcard, particularly access of high-speed interface to have the smart card of high-speed interface, such as SIM card with USB interface or SD/MMC interface.This causes the mobile phone user not having under the situation of special stube cable, and the canned data that is difficult on realization smart card stored information and the own computing machine of user is carried out synchronous fast and renewal.Particularly along with the memory span that embeds on the smart card further increases, from traditional several kilobyte magnitudes to the megabyte magnitude, even during the gigabyte magnitude, this contradiction will be more outstanding.
Summary of the invention
The objective of the invention is to the demand to the synchronous and renewal between data on the smart card with large capacity and the user's computer at present user, a kind of novel card read connection device for smart card is provided, and this equipment can read, write the data on the smart card by USB on the smart card or SD/MMC interface easily and synchronously.
Technical scheme of the present invention is as follows: a kind of card read connection device for smart card, comprise a stationary installation that can be placed in the computing machine extending space, on this stationary installation, be provided with the physical support that can carry smart card, this physical support is provided with 8 signal contact points that the contact position with standard intelligent card matches, and the signal contact point is connected with the computer-internal bus; Wherein the signal wire of 5 signal contact points according to ISO/IEC 7816 agreements be defined as respectively power supply,, reset, clock and data line, the signal wire of all the other 3 signal contact points is defined as data line, control signal wire and the clock cable of smart card high speed interface respectively.
Aforesaid card read connection device for smart card, wherein, the described physical support that carries smart card is a pallet that plays fixation, this pallet can be controlled it by a mechanical button and insert and eject stationary installation.
