Description
Technical field
The utility model relates to intelligent card reader field, is specifically related to a kind of Network Smart Card Reader-Writer.
Background technology
Card reader (Reader) is a kind of card-reading apparatus, because kind of cards is more, so the implication coverage of card reader is wider.According to the difference of type of card, IC-card card reader can be divided into, be comprised Contact Type Ic Card, be followed ISO7816 interface standard; Contactless IC Card Reader, follows ISO14443 interface standard, remote card reader, follows ETC GB GB20851 interface standard; Divide by port type and can be divided into serial port card reader, parallel port card reader, USB card reader.
When carrying out IC-card batch production, the procedure quantity of write IC card chip is increasing, and the time of needs is more and more longer, and production efficiency declines gradually; Because workshop equipment is more, current USB line length distance high speed transmission data are easily made mistakes, and when low speed transmits, production efficiency is low, does not reach requirement, therefore needs the card reader product that a long transmission distance, antijamming capability are strong, transmission speed is fast.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of Network Smart Card Reader-Writer, and this card reader connects Ethernet, utilizes the advantage of network to realize convenient networking, has long transmission distance, and antijamming capability is strong, the feature that transmission speed is fast.
For reaching above object, the technical solution of the utility model is: a kind of Network Smart Card Reader-Writer, comprise primary processor, clock chip, IC-card interface chip, described clock chip is connected respectively with primary processor and IC-card interface chip, described IC-card interface chip is connected with golden finger, described primary processor is also connected with the network interface unit based on tcp/ip communication pattern, is connected into Ethernet by described network interface unit.
Further, described network interface unit comprises Ethernet chip and band lamp network interface.
Further, described primary processor is also connected with flash storage.
Further, described primary processor is STM32 single-chip microcomputer.
Further, described IC-card interface chip is connected with golden finger by ICC card interface.
Further, the power module of powering for whole equipment is also comprised.
Effect of the present utility model is: after adopting the utility model technology, based on tcp/ip communication, convenient and swiftly can be connected into Ethernet, by network reception with send information to PC/ server, completes corresponding operation; Utilize the advantage of network to realize convenient networking, have long transmission distance, antijamming capability is strong, the feature that transmission speed is fast.
Accompanying drawing explanation
A kind of Network Smart Card Reader-Writer structured flowchart that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
Be illustrated in figure 1 a kind of Network Smart Card Reader-Writer disclosed in the utility model, comprise primary processor, primary processor connects IC-card interface chip by clock chip, IC-card interface chip golden finger connects, described primary processor is also connected with the network interface unit based on tcp/ip communication pattern, is connected into Ethernet by described network interface unit.
In the present embodiment, Network Smart Card Reader-Writer is a Contact Type Ic Card card reader based on tcp/ip communication.Wherein, primary processor Mcu adopts STM32 single-chip microcomputer, and in describing below, primary processor is referred to as STM32; Network interface unit comprises Ethernet chip and band lamp network interface, and the connection of STM32 and network interface unit is connected with Ethernet chip respectively by spi bus, by LED be with lamp network interface to be connected to realize.Wherein, be with on lamp network interface and be connected with transformer and corresponding diode; Preferably, Ethernet chip is W5500 type.Network Smart Card Reader-Writer is connected with outside netting twine by band lamp network interface, and by connecting Ethernet based on TCP/IP network interface unit, realize the telecommunication of card reader, described Network Smart Card Reader-Writer input power is 5V, connects power supply by cable idle in netting twine.
Card reader is also connected with FLASH memory, and in the present embodiment, FLASH memory model used is W25Q64; STM32 is connected with FLASH memory by SPI.
STM32 is connected with golden finger with IO2 by power lead VCC, input/output port IO1, and golden finger is the link between internal memory and memory bank, and all signals are all transmitted by golden finger.
Golden finger is connected with IC-card interface chip by ICC card interface; IC-card interface chip is connected with UART and STM32 by clock chip; Preferably, IC-card interface chip model is TDA8035; Clock chip is DS1086L.
During operation, netting twine is accessed network interface, connect Ethernet, communicated with PC/ server by network.Mainly contain three kinds of mode of operations below:
Pattern 1: single instrction interactive mode.The instruction that PC/ server issues, primary processor to instructions parse, then operates after receiving instruction accordingly, read-write SPIFLASH, read-write contact type CPU card; Send response message by network to the PC/ webserver after each operation completes, and received by PC, the webserver and process.
Pattern 2: instruction batch mode.All instructions that will perform are packaged into a file according to certain format, and by SPIFLASH chip under this file download.Then by host processor chip successively sense order from SPIFLASH chip, resolve instruction and operate accordingly, operational factor is set, configurable clock generator, read-write CPU card etc.When the every bar command operating performed is correct, continue to perform next instruction, to the last by complete for this document analysis, return one to server and run correct state.If certain instruction the term of execution, there occurs mistake, then no longer perform instruction below, and return error status code to server.
Mode 3: mutual and batch processing cross-mode.This has merged the type of two kinds of situations above, when primary processor performs instruction batch mode, to be resolved in batch file when needing result return service device after present instruction runs, then by this instruction operation result return service device, the new data issued after waiting for server computing, after server issues data, the instruction below in these data and file is integrated by primary processor again, proceeds the execution of instruction below.
In sum: the utility model utilizes the advantage of network to realize convenient networking, has long transmission distance, antijamming capability is strong, and the feature that transmission speed is fast, can realize the high speed mass hair fastener of card-issuing equipment.
It will be understood by those skilled in the art that device described in the utility model is not limited to the embodiment described in embodiment, specific descriptions above, just in order to explain the purpose of this utility model, are not for limiting the utility model.Those skilled in the art draw other embodiment according to the technical solution of the utility model, belong to technological innovation scope of the present utility model equally, and protection domain of the present utility model is limit by claim and equivalent thereof.
