可实时转换协议的非接触式集成电路卡及卡系统 Real-time transfer protocol contactless IC card and card system

技术领域 FIELD

本发明涉及一种具有实时协议转换功能的非接触式集成电路卡和包括该非接触式集成电路卡的卡系统。 Contactless IC card and comprising the non-contact IC card of the card system of the present invention relates to a real-time protocol conversion function.

背景技术 BACKGROUND

数据发送系统是众所周知的,并被广泛用于与位置遥远的便携数据设备交换信息和进行交易。 Data transmission systems are well known and widely used to exchange data with the position distant portable device information and transactions. 这样的便携数据设备通常被称为卡、智能卡或标签(tag)。 Such a portable device is often called data card, smart card or tag (tag). 同样,数据发送终端通常被称为读卡器。 Similarly, the data transmission terminal is often called a card reader. 在这样的数据发送系统中,当卡进入终端/阅读器的激励(excitation)区域时,交易开始。 In such a data transmission system, when the card into the terminal / reader excitation (excitation) region, the transaction begins. 具体地说,终端产生功率信号和数据信号(也称为信息信号),并使用载波信号来传送该信息信号。 Specifically, the terminal generates a power signal and a data signal (also referred to as information signal), and the use of a carrier signal to transmit the information signal. 载波信号的检测和接收给卡远程供电,并且使卡电路能够执行它的预期功能。 Carrier signal detection and receive remote power supply to the card, and the card circuit capable of performing its intended function.

可以使用远程供电的(即,非接触式的)数据设备(即,卡)来执行多种任务,包括防盗、人员或材料识别和控制、自动收费、钱和服务交易的记录及控制等。 You can use the remote power supply (ie, non-contact) data devices (ie, cards) to perform a variety of tasks, including theft, personnel or material identification and control, automatic fare collection, recording and control of money and services transactions. 虽然ID标签可能较不复杂,但所谓的智能卡往往更复杂,并且可以包括一个或更多处理器以及本地存储器来存储和处理信息。 Although the ID tag may be less complex, but so-called smart card often more complex, and may include one or more processors and a local memory to store and process information. 非接触式IC卡(或者非接触式智能卡)的特定变种作为接近式卡(vicinity card)而为人所知,并且,其使用被称为ISO/IEC 14443标准的通信协议。 Non-contact IC card (or a contactless smart card) of a particular variant as a close-card (vicinity card) and known, and its use is known as ISO / IEC 14443 standard communication protocols. 在ISO/IEC 14443中定义了接近式IC卡的物理特性、它的射频(RF)功率和信号接口、它的初始化和防冲突以及发送协议。 ISO / IEC 14443 defines the physical characteristics of the proximity of the IC card, its radio frequency (RF) power and signal interface, its initialization and anti-collision and sending protocol. 具体地说,在ISO/IEC 14443中描述了被称为A-类型和B-类型的两种通信信号接口。 Specifically, in the ISO / IEC 14443 describes two communication interface type is called A- and B- type.

在A-类型接口中,使用RF工作领域中的振幅相移键控(ASK)100%调制的技术来执行读卡器(或终端)与IC卡之间的连接,并且以改进的miller(密勒)码的格式来把将被发送的数据编码。 A- type interface in use in the field of RF amplitude phase shift keying (ASK) 100% modulation technique to perform connected card reader (or terminal) and the IC card, and to improve the miller (secret Le) data encoding format of the code will be sent to the. 在B-类型接口中,使用ASK 10%调制来执行读卡器(或终端)与IC卡之间的连接,并且以NRZ-L非归零电平(NRZ-L)码的格式来把将被发送的数据编码。 In B- type interface, using ASK 10% modulation is performed connecting the card reader (or terminal) and the IC card, and to NRZ-L non-zero level (NRZ-L) code format to the data encoding to be transmitted. 由于在ISO/IEC 14443中详细描述了A-类型和B-类型接口,因此将省略关于它们的详细描述。 Since a detailed description of the type A- and B- type interface in ISO / IEC 14443, and therefore a detailed description will be omitted about them.

根据背景技术的IC卡支持A-类型或者B-类型接口。 Supports A- or B- type interface based on the type of background art IC card. 如上所述,由于A-类型和B-类型编码及调制彼此不同,因此支持所述通信信号接口之一的IC卡只能在支持对应的通信信号接口的读卡器中使用。 As mentioned above, due to the type A- and B- type coding and modulation different from each other, thus supporting one of said communication signal interface IC card can only be used in support of the corresponding communication signal interface card reader. 如果读卡器支持A-类型通信协议,则不可能和它一起使用只支持B-类型接口的IC卡,反之亦然。 If the reader supports A- type of communication protocol, and it is impossible to use with only the support of B- type of interface IC card, and vice versa.

UART 160包括:发送/接收(还是TRX)控制块161;移位寄存器162;码转换块163;定时和控制块164;奇偶校验控制块165;CRC块166;以及首标(header)检测块167。 UART 160 include: sending / receiving (or TRX) control block 161; a shift register 162; code conversion block 163; timing and control block 164; parity control block 165; CRC block 166; and a header (header) detection block 167.

参考图5,CPU 120将与协议设置和UART驱动、发送/接收模式、发送/接收速率、错误处理方法、协议实施选择、发送/接收结束控制等相关的控制信号发送到TRX控制块161。 With reference to FIG. 5, CPU 120 sets the protocol and the UART driver, transmission / reception mode, the transmission / reception rate, error handling, protocol implementation choices, transmission / reception end of the relevant control signal is sent to the TRX and other control block 161. TRX控制块161控制UART操作的流程。 TRX control block 161 controls the flow of UART operation. 发送数据例如周期性地、例如逐位地移出移位寄存器162,例如移出LSB位置,然后被发送到发送码转换块163a。 Periodically transmitting data such as, e.g., bit by bit out of the shift register 162, for example, out of LSB position, and then transmitted to the transmission code conversion block 163a. 发送码转换块163a根据所选择的接口类型而将所输入的发送数据转换为码数据。 Send code conversion block 163a according to the interface type selected and sends the data input is converted to code data. 通过模拟接口块180来调制以这种方式转换的码数据,并将调制后的信号通过天线200发送给读卡器或终端。 By modulating the analog interface block 180 in this way to convert code data, and transmits the modulated signal to the reader or terminal through an antenna 200. 如果选择了A-类型通信信号接口,那么发送码转换块163a将从奇偶校验控制块165获得的奇偶校验信息添加到从移位寄存器162输出的数据中。 A- If you select the type of communication signal interface, then add the code to convert the parity information is sent from the parity block 163a control block 165 to the data obtained from the shift register 162 output.

通过模拟接口块180的解调制器404和405而将通过天线200接收的RF信号单独解调制(产生RF信号的多个解调制后的版本),然后将解调制后的信号发送到码转换块163。 Block 180 via analog interface 404 and the demodulator 405 will demodulate (version generating a plurality of demodulated RF signal after) the received RF signal via antenna 200 alone, and then sends the demodulated signal after the code conversion block 163. 由解调制器404解调制的改进的镜像码信号被接收码转换块163b转换为NRZ-L码。 By demodulator 404 demodulates improved image code signal is received the code conversion block 163b converts NRZ-L code. 选择器163c根据所选择的接口而有选择地输出接收码转换块163b的输出和由解调制器405解调制的信号。 Selector 163c selectively outputs the received code conversion block output and the demodulator 405 demodulates the signal 163b based on the selected interface. 从码转换块163输出的数据被例如逐位地输入到移位寄存器162,例如,输入到LSB位置。 Data output from the code conversion block 163 is such as bit by bit input to the shift register 162, for example, the input to the LSB position. 如果移位寄存器变得充满例如具有表示一字节的单位的数据,则将存储在移位寄存器162中的数据发送给CPU 120。 For example if the shift register becomes filled with data representing a byte unit, the data will be stored in the shift register 162 is sent to the CPU 120. 例如,如果移位寄存器162变得完全充满,则TRX控制块161将中断信号输出给CPU 120,然后,CPU 120响应于该中断信号而取走存储在移位寄存器162中的数据。 For example, if the shift register 162 becomes completely filled, the TRX control block 161 outputs an interrupt signal to the CPU 120, and then, CPU 120 in response to the interrupt signal and the removal of data stored in the shift register 162.

控制和定时控制块164从模拟接口块180接收时钟,并在TRX控制块161的控制下生成用于UART 160的时钟。 Control and timing control block 164 receives a clock from the analog interface block 180, and the control block 161 in TRX for UART 160 generates a control clock. 如果选择了A-类型接口,则奇偶校验控制块165确定在接收操作中是否有奇偶校验错误,然后在发送操作期间生成关于发送数据的奇偶校验信息。 If you select the A- type interface, the parity control block 165 determines whether the receiving operation has a parity error, and then generate parity information about sending data during transmission operation. 循环冗余校验(还是CRC)块166被配置用来确定在所发送的数据中是否有错误。 Cyclic redundancy check (or CRC) block 166 is configured to determine the transmitted data for errors. 首标检测块167接收由模拟接口块180解调制的信号,并检测当前输入信号的首标信息(例如,在B-类型接口情况中的SOF信息)。 Header detection block 167 is received by the analog interface block 180 demodulates the signal, and detects the current input signal the header information (e.g., SOF B- type information in the case of the interface). TRX控制块161根据首标检测块167的检测结果来控制移位寄存器162。 TRX control block header detection block 161 according to the test results 167 to control the shift register 162.

如果将非接触式IC卡100设置为A-类型的通信信号接口,则非接触式IC卡100只能与具有A-类型的通信信号接口的读卡器通信,反之亦然。 If the non-contact IC card 100 is set to A- type of communication interface, the non-contact IC card reader 100 can communicate with A- type communication interface and vice versa. 换句话说,尽管非接触式IC卡100具有以任意一种接口工作的能力,但是它将只以所述接口的一种或另一种工作,除非对寄存器140中的设置进行改变。 In other words, although the non-contact IC card 100 has the ability to interface to any of a work, but it will only work in one or another of the interface, except for the register 140 to change the settings. 因此,非接触式IC卡100的可替换装置包括可选的触发(toggle)能力,以便例如周期性地在A-类型和B-类型之间转换寄存器140中设置的通信信号接口。 Therefore, non-contact IC card can replace device 100 comprises an optional trigger (toggle) the ability to, for example periodically between A- and B- type conversion type communication interface set in the register 140. 利用这样的触发能力,有可能与具有B-类型接口的读卡器和具有A-类型接口的读卡器通信。 With such triggering capabilities, it is possible to have a B- type of interface card reader and reader communication interface type and have A-. 这样的转换能力可以使用另外的例如硬件(例如,通过使用虚线而被指示为可选的定时器121)或者(例如在CPU 120上运行的)软件等来提供。 This conversion capability can be used, for example, additional hardware (e.g., by using a broken line and is indicated as an optional timer 121), or (e.g., running on the CPU 120) software provided.

与非接触式IC卡100不同,非接触式IC卡300不会根据存储在寄存器340中的先前选择的接口来与读卡器通信,而是在实时地分析从读卡器发送的RF信号、并根据分析结果而自适应地设置寄存器340中的接口类型之后与读卡器通信。 With the non-contact IC card 100 is different from the non-contact IC card 300 does not communicate with the reader to, but in real-time analysis of the RF signal transmitted from the card reader connector according to the previously selected is stored in the register 340, and adaptively register 340 after setting the interface type to communicate with the reader based on the analysis results. 所选择的接口类型被实时地转换,以便与读卡器的接口类型相匹配。 The selected interface type is converted in real time to match the type of interface with the reader.

例如,在A-类型通信中,读卡器将短帧信号作为REQA命令(26H或0110010B)发送给非接触式IC卡300。 For example, the A- type of communication, the reader signal as the short frame REQA command (26H or 0110010B) sent to the non-contact IC card 300. 模拟接口块380的解调制器404和405的每一个将所输入的短帧信号解调制。 Analog interface block 380. Each demodulator demodulates a short frame signal 404 and the input 405. 如上所述(参见图3-4),如果接收到A-类型的RF信号,则由解调制器404和405单独解调制的信号具有相同的波形。 As described above (see Fig. 3-4), if the received RF signal A- type, by demodulator 404 and 405 separately demodulated signals have the same waveform. 通过码转换块364,把由解调制器404解调制的信号从改进的镜像码转换为NRZ-L码。 By code conversion block 364 to the demodulator 404 demodulates the signal from the improved image code NRZ-L code. 同时,首标检测块367检测在由解调制器405解调制的信号的首标部分中是否包含SOF信息。 Meanwhile, the header detection block 367 detects the header portion by the demodulator 405 demodulates the signal contains information SOF. 在A-类型通信中,TRX控制块361将辨识出在解调制后的信号的首标部分中不包含SOF信息,并相应地设置标志寄存器400中的值,然后将中断信号发送给CPU 320。 In the A- type communication, TRX control block 361 will be identified in the header portion of a signal demodulated after SOF does not contain information, and sets the value of the flag register 400, and then sends an interrupt signal to the CPU 320.
