Description

说 明 书 射频 SIM卡、 射频读卡器及射频通信的磁感应控制方法 技术领域
本发明涉及射频无线通信技术， 特别是涉及射频 SIM卡、 射频读卡器及射 频通信的控制方法。 背景技术
现有移动通信技术的用户识别模块 Subscr iber Ident i ty Mode l , 简称 SIM 卡， 被广泛应用到移动通信终端上。 随着科学技术发展， 通过各种方法在普通 移动通信终端的 SIM卡体内增设各种智能电路模块， 使 SIM卡除了具有基本的 SIM卡功能外，还增加了其它更加贴近于生活的功能，射频 SIM卡就是其中之一。 申请人就射频 SIM卡已经提出过一款中国专利申请，申请号为 200710124354. 7。 射频 SIM卡采用有源射频技术， 使普通的 SIM卡能够具备电子钱包等移动支付 功能， 或者门禁通行等消费应用功能。
首先， 由于射频 SIM卡取电自移动终端的电池， 其进行射频工作时会消耗 移动终端电池的电能， 因此对移动终端的待机时间造成影响。 针对这一问题， 目前降低射频 SIM卡功耗采取的方法是： 射频 SIM卡定时查询是否存在射频交 易数据来确定是否需要进行交易处理。 这种方法虽然能够将射频 SIM卡的功耗 降低到一定程度， 但采用这种方式， 射频 SIM卡的射频收发模块和微控制器还 是会在许多其实没有射频交易数据时因被查询而启动工作， 消耗移动终端电池 的能量， 因此仍然对移动终端的待机时间存在明显的影响。
其次， 所述射频 SIM卡在某些功能的应用场合中 （例如将射频 S IM卡兼用 作公共交通收费 IC 卡等射频智能卡）， 为了防止出现误读卡和错读卡的现象， 必须将射频 SIM卡与射频读卡器的无线通信距离控制在一个很小的范围内。 因 此， 上述无线通信距离的控制就成为射频 SIM卡无线通信系统的最主要实现难 点。 现有技术通过衰减射频 S IM卡信号强度的方法来控制射频 S IM卡与射频读 卡器的无线通信距离。 但是， 射频 S IM 卡通常装配于移动通信终端内， 受移动 通信终端的屏蔽效果影响， 在装配相同无线收发功率的射频 S IM卡的情况下， 通过不同型号移动通信终端的射频信号无线收发功率也不同。 因此， 必须对不 同型号的移动通信终端定制具有不同无线收发功率的射频 S IM卡以控制其无线 通信距离在合适的范围内， 这势必将导致在使用射频 S IM卡之前， 使用者必须 根据移动通信终端的类型对射频 S IM卡的无线收发功率进行校准； 另外， 如果 使用者更换移动通信终端， 在每次更换后还需要对射频 S IM 卡再次进行无线收 发功率校准， 这种繁瑣的校准过程不仅令使用者感到不方便， 而且不利于射频 S IM卡的推广应用。 发明内容
本发明要解决的技术问题在于避免上述现有技术的不足之处而提出一种能 有效降低功耗而对移动终端待机时间几乎没有影响的射频 S IM卡和与之相适配 射频读卡器， 以及射频通信的磁感应控制方法。
本发明解决所述技术问题可以通过采用以下技术方案来实现：
设计、 使用一种射频 SIM卡，包括 SIM卡本体、 第一射频收发模块、 第一射 频天线和第一微控制器 , 所述第一射频收发模块分别与所述第一射频天线和第 一微控制器电连接， 还包括磁感应模块， 该磁感应模块与所述第一射频收发模 块电连接； 所述磁感应模块未感应到相适配的磁场信号时， 所述第一射频收发 模块和第一微控制器都处于休眠状态； 所述磁感应模块感应到相适配的磁场信 号时， 所述被感应到的磁场信号经转换成电信号激活所述第一射频收发模块， 该第一射频收发模块再检测是否有射频载波信号而确定是否产生外部中断唤醒 设计、 使用一种与所述射频 S IM卡相适配的射频读卡器， 包括第二射频收 发模块、 第二射频天线和第二微控制器， 所述第二射频收发模块分别与所述第 二射频天线和第二微控制器电连接， 还包括磁场产生模块， 用于产生感应磁场； 所述射频 SIM 卡接近所述射频读卡器时， 感应到所述磁场产生模块产生的磁场 信号， 才将射频 S IM卡的第一射频收发模块激活并唤醒第一微控制器。
提出一种射频通信的磁感应控制方法， 基于射频 S IM卡和与之适配的射频 读卡器之间的数据通信， 包括如下步骤：
A.在射频读卡器内设置磁场产生模块；
B.在射频 SIM卡内设置磁感应模块， 该磁感应模块与射频 S IM卡的第一射 频收发模块电连接；
C.通常状态下， 也就是所述射频 S IM卡未接近所述射频读卡器时， 令射频 S IM卡的第一射频收发模块和第一微控制器处于休眠状态；
D.所述射频 S IM卡接近所述射频读卡器时， 射频 SIM卡的磁感应模块感应 到射频读卡器磁场产生模块的磁场信号； 被感应到的所述磁场信号经转换成电 信号激活所述第一射频收发模块；
E.所述第一射频收发模块再检测是否有射频载波信号而确定是否产生外部 中断唤醒第一微控制器， 若有， 所述第一微控制器被唤醒， 所述第一射频收发 模块进入正常工作状态与所述射频读卡器的第二射频收发模块交换数据， 并将 交换所得数据传送给各自对应的第一微控制器和第二微控制器处理。
所述射频 S IM卡的磁感应模块是螺线管线圈、 霍尔器件或磁感应开关。 所述射频 SIM卡的第一射频收发模块被磁感应转换的电信号激活的门限值 可以调整。
所述射频 SIM卡的第一射频收发模块和射频读卡器的第二射频收发模块工 作的频段为超高频 SHF频段、 甚高频 VHF频段或者是特高频 UHF频段。 同现有技术相比较， 本发明射频 SIM卡、 射频读卡器及射频通信控制方法 的技术效杲在于： 1. 在射频 SIM卡中设置磁感应模块， 在射频读卡器内设置相 适配的磁场产生模块， 并使射频 S IM卡的第一射频收发模块和第一微控制器在 磁感应模块未感应到相适配的磁场信号时， 也即没有进行射频交易数据的通常 状态下都处于休眠状态； 当所述第一射频收发模块感应到适配的磁场信号时， 也即射频 SIM 卡接近射频读卡器要刷卡进行射频交易数据时， 第一射频收发模 块和第一微控制器才开始启动正常工作模式， 这样有效地降低射频 SIM卡的功 耗， 因此对移动终端的待机时间几乎没什么影响； 2.本发明借助磁感应技术来 有效触发射频收发模块启动工作， 由于磁场能量传递和感应与移动通信终端本 身的外型结构相关性很小， 从而保证了不同的移动通信终端中的射频 SIM卡的 感应信号强度一致性， 便于射频 SIM的有效推广应用； 3. 射频 SIM卡的第一射 频收发模块激活后要检测有射频载波信号才确定产生外部中断唤醒第一微控制 器， 进一步有效降低射频 S IM卡的功耗， 并且， 射频 SIM卡的第一射频收发模 块被感应电信号激活启动的门限值可以调整， 这样可以将读卡距离有效地控制 在一定范围内， 且避免误读卡和错读卡的现象。 附图说明
