Description

具有任选辅助电源的非接触式电子通信装置
本发明涉及非接触式电子通信系统，其中，至少一个不具有由用户携带的内部电源的电子通信装置通过电磁信号与一电子询问/读/写装置进行通信。
这种非接触式电子通信系统被用来，例如控制对滑雪道、房屋、车库、公共运输等的访问，因为没有任何接触，所以提高了用户通道的速度，同时允许在所携带的电子装置和电子询问/读/写装置之间进行信息交换，因而可根据一定的标准来管理访问。
电子询问/读/写装置例如以无线电频率发射电磁信号，该信号被用户所携带的电子通信装置所检测，并且，一方面用作信息交换用传输媒介，另一方面用作向电子通信装置提供电能的能源。为此，后者包括，例如图1中的简图所示，一天线10，该天线由包括一线圈14和一电容16的谐振电路12组成。来自询问/读/写装置的由天线10接收的无线电频率信号被施加于解调器18，该解调器检测由询问/读/写装置发射的包含二进制信息的低频调制信号。
为了解释这些二进制信息信号，由数字处理电路20对其进行处理，如果必要，产生一二进制信号形式的响应，这些信号通过调制器24发送至该询问/读/写装置，该调制器由连接到谐振电路12终端的一开关22和一负载阻抗(30)表示。
天线10所检测到的无线电频率信号还被施加于整流和滤波电路26，该电路在终端A和B处将电源电压Vcc提供给电路18、20和24。
以配置在银行信用卡类型的塑料卡中的微型电路28的形式来产生根据图1的非接触式电子通信装置，天线的线圈14沿卡的周围配置，整个构成一通信模块MC。
值得注意的是，考虑到谐振电路12的调谐调节，电容16的一部分在微型电路28中，一部分在其外。
这种微型电路也可被配置在表的外壳中，该外壳的材料被设计成允许电磁信号到达外壳内的天线。
这种非接触式电子通信系统具有一主要缺点，即，限制了其作用距离，例如，由于微型电路的实际有效电源不充足，除询问/读/写装置与天线之间的一定距离之外，在读/写模式下频率为13.65MHz时的作用距离为几十厘米。
另外，电源的不充足还限制了速度，因而限制了微型电路的计算能力，这导致不能保证在短的时间间隔中实现需要大量数据处理和/或加密计算的复杂处理。
并且，根据当前的规则，由于询问/读/写装置的电源被限制以基本上不妨碍邻近安装和环境，所以也不能增加该询问/读/写装置的发射能量。
因此，本发明的目的是提供一种非接触式电子通信装置，该装置具有最大作用距离，并具有比已有的装置大的计算能力。
通过修改该非接触式电子通信装置来实现该目的，因此，可将该装置连接到一个设置在例如卡夹持器或表等支撑上的一般物体的电源，例如电池等上。
因此，本发明涉及一种包含在模块中类型的非接触式电子电磁通信装置：
接收电磁信号的装置，
处理接收的电磁信号的装置，和
为了在两个输出端向处理装置提供电源电压而整流和滤波接收的电磁信号的装置，
其特征在于：还包括
支撑电源的装置，和
将所述电源连接到所述整流和滤波电路的输出端的装置
该连接装置还包括一开关，以建立或切断电源和整流和滤波电路的终端之间的连接。
该连接装置包括：
在模块中，用来将整流和滤波电路的输出端连接到第一接触端点上的导线，
在支撑装置中，用来将电源连接到第二接触端点上的导线，和
将所述第一和第二接触端点连接到一起的装置。
当用银行类型卡来携带该模块时，
支撑电源的装置包括一卡夹持器，和
连接所述第一和第二接触端点的装置包括在卡夹持器中导引和夹持该卡的装置，以使所述第一和第二接触端点重合。
当在外壳中设置该模块时，
支撑电源的装置包括例如具有电池的表等物体，
该第一接触端点包括一设置在模块外壳上的连接器，
该第二接触端点包括一设置在表外壳上的连接器，和
所述连接器彼此配合以建立电连接，并被模块所携带的夹持装置夹持在该位置上，该物体支撑该电源。
连接器可以是彼此相对设置的接线柱或凸/凹型连接器。
当支撑物体为手机时，电池充电端被用来建立电池和模块之间的连接。
参照附图和实施例的描述，本发明的其它特征和优点将变得明显，其中，

对于由已有技术已知的元件而言，将不再描述非接触式电子装置的图1中的图表。
为了实现本发明，为了通过导线32、34将整流和滤波电路26的输出端A和B与设置在包含微型电路28和谐振电路天线10的模块MC之外的两个接触端点36和38相连接，必须进行修改。
所谓的非接触式通信模决MC通常容纳于塑料卡40的厚度内，天线10的线圈14以一圈或多圈被容纳在卡的周围。根据本发明，接触端点36和38被设置在卡40的表面上。
卡40与卡夹持器PC配合，通过例如滑动以被插入在具有阻挡部46的凸起凹槽42和44中。卡夹持器用作容纳于卡夹持器厚度内的电池48的支撑。用容纳于卡夹持器厚度内的导线50和52来连接电池48的终端，以接触设置在卡夹持器表面上的终端56和58，因而分别与卡40的接触端点36和38配合，应该明白，图2A中的卡40必须翻转以插入凹槽42和44中。
假设开关60在例如用户处理的导线50上串联连接，根据用户需要，电池48和接触端点56和58之间的电连接可以是连续或间断的。
通过将卡40与卡夹持器PC相结合，微型电路28被提供电池48的电压，该电压可替换或加到整流和滤波电路26所提供的电压上。提高到一更大的检测距离，更长的处理用期间和更高的计算速度，由于电源电压Vcc不依赖于卡40和询问/读/写装置之间的距离，因此电源电压Vcc是不变的。
存在被称为“结合卡(combicard)”的微型电路卡，该卡被设计成一方面与间隔一定距离的询问/读/写装置通信，另一方面还与具有触点的询问/读/写装置通信。为此，例如根据ISO7816-2，这些结合卡具有连接到常规类型接触端点上的微型电路28。
假设根据上述标准，接触端点56和58具有一种排列，则这些结合卡可与卡夹持器PC一起用于本发明的上下文中。
通常，非接触式卡40的接触端点36和38与卡夹持器PC的这些接触端点56和58符合标准，事实上，该标准允许由卡夹持器PC使用结合卡。
开关60可以是容纳于卡夹持器厚度中的按钮微动开关型的开关，该按钮例如设置在与接收卡40的夹持器的面相对的面上。
电池48为外部平整型的，为了其可能的替换，将其容纳在卡夹持器PC的腔中。
自然地，微动开关和其按钮可容纳于该外部平整型电池的空穴中。
在根据图2A和2B的本发明的典型实施例中，非接触式电子模块MC由银行信用卡型塑料卡40携带，而电池48由卡夹持器PC携带，在卡夹持器PC上插有卡40以在终端36、38、56和58之间建立电接触。
本发明还适用于任何为了具有连接接点36和38以与由一物体，例如电子表或手机等携带的电池接触端点连接而进行修改的非接触式电子模块。
为了具有等同于卡夹持器PC的终端56和58的接触端点，必须修改携带电池的物体，为了适用于携带电池的物体终端56和58，这同样适用于模块的接触端点36和38。图4至11表示非接触式电子模块和具有电池的表之间的结合的两个实例，而图12-13表示非接触式电子模块和手机之间的结合的两个实例。
电子型表MO(图3至11)包括一电子电路(未图示)，具有一个或多个标度盘64、66、68的显示装置(62)和一电源电池70，这三个元件设置在外壳72上，不同控制钮74位于外壳的周围。通过连接接合部78由腕带76将外壳72带在手腕上。
根据本发明，电池70不仅连接到电路和标度盘上，而且还连接到例如凹型的连接器80(图3至9)上，该连接器位于表外壳72的侧部上。该连接器80与包含微型电路28、天线线圈14和电导线32和34的外壳84所具有的凸连接器82相配合。微动开关86与导线32串联连接，以在用户请求时提供或不提供微型电路28。
外壳84通过搭锁凸连接器82和凹连接器80、并通过一凸缘88来安装于表的背面，凸缘88的下面配有外壳84的减薄部分90。
除了设置在表的侧面上外，电池70的输出连接器也可设置在表外壳的背面上，两个触点100和102(图10和11)分别与在外壳108上的两个接线柱104和106配合，该外壳108包含有电子微型电路28、天线线圈14和电导线32和34。
接线柱104和106由电导线32和34连接到电子微型电路28的点A和B上，导线32和34中的一个具有由用户起动的微动开关110。
外壳108用两个托架112、114安装在表的背面上，两个托架112、114分别与设置在表背面中的两个凹槽116和118配合。外壳108具有用于松开的减薄周围部分120。
当电池在手机TM上时(图12)，电子微型电路28及其天线，例如设置在一个面上具有两个凸触点的平等立体面外壳130内。这两个触点被插入手机上用于充电电话电池的凹触点132内。微动开关134位于电导线32或34上，通过外壳130上带有的按钮由用户来起动。
一些手机138(图13)配有连接器140(图13)，其中，为了对手机加入额外的功能而插入银行类型的卡。此时，图2A的非接触式卡40可插入连接器140以将其触点36和38连接到连接器140的电源触点上。开关142被设置在手机138上。
值得注意的是，包含电源的卡夹持器PC或手机138带有开关60或142，而包含微型电路28的外壳84或130带有开关86或134。
值得注意的是，电源可以是充电电池、蓄电池，可或不可拆卸的，或所谓的太阳能电池，例如光电型的。
