Description

识别系统
技术领域
本发明涉及一种关于识别系统的方法,还涉及一种识别系统。
背景技术
本发明涉及关于公司、需要授权访问的场所、机场、诸如运动场的兴趣和活动场所、以及需要识别系统的其他场所的对个人和授权人员的控制。
已知的自动识别系统典型包括个人携带的ID标签、以及ID标签读取设备。
使用射频的已知自动识别系统,所谓的RFID(射频标识)包括至少一个应答机和至少一个通信器。一种已知类型的应答机将包括天线、调制器、存储器、以及调制器控制逻辑电路。一个这种已知的应答机被设计为能够接收来自通信器的输出信号,并且以已调制状态反射此信号。通信器被设计为能够接收和读取由应答机所反射和调制的信号。
包括应答机的ID标签可以放置于待识别的对象上的个体上。包含在该应答机中的信息可以由通信器在例如5米距离的给定短距离之外读取。
为了提高关于从应答机到通信器传送信息的安全性和可靠性,包括了一种所谓的校验和,该校验和是通过应答机中的电路根据适当的算法基于存储在应答机中的数据计算的,所述校验和与数据传送相结合地从应答机被传送到通信器。
在通信器接收到由应答机反射和调制的信号之后,在通信器中发生基于一种算法的相应计算。在通信器中对校验和进行比较。
上述已知技术的一个问题是,校验和的计算需要电子电路,这又需要能量,从而增加了应答机所承担的成本。
发明内容
本发明的目的是提供一种系统,该系统包括应答机,该应答机的制造成本低,并且能量消耗低到以至于消除了应答机具有自身电池的需要。
上述问题通过本发明来解决。
从而,本发明涉及一种关于识别系统的方法,在该识别系统中,应答机反射来自通信器的询问信号,其中所述反射信号已经用可以由通信器读取的数据进行调制,其中所述携带数据的调制包括基于存储在应答机存储器中的数据所计算的校验和,并且其中,本发明特征在于在应答机存储器中永久存储该校验和。
本发明还涉及一种应答机,该应答机包括至少一个天线,至少一个存储器,以及至少一个用于反射和调制来自通信器的询问信号的装置,其中所述反射信号包括携带数据的调制,其中所述反射信号能够由通信器读取,其中所述携带数据的调制包括基于存储在应答机存储器中的数据所计算的校验和,并且其中所述发明的特征在于,该应答机包括存储在应答机存储器中的校验和。
附图说明
图1是示出了本发明识别系统的示意图。
具体实施方式
现在将部分参考在附图中所图示的示例性实施例来更加详细地描述本发明。
图1是示出了包括天线2和ROM存储器3的应答机1的示意图。图1中还示出具有天线5、6、存储器7、处理器8、以及数据系统9的通信器4。询问信号10和反射调制应答信号11也在图1中示出。
本发明的一个优选实施例在于一种方法,其特征在于使得基于一种算法计算校验和,其中该算法对于一组应答机是相同的,并且与其他组应答机相比是不同的。
本发明的又一个优选实施例在于一种方法,其中每当读取应答机1时使得在通信器4中发生根据所述算法的计算,并且其中,所计算的校验和与由反射信号11传送的所存储的校验和进行比较。
在本发明的一个优选实施例中,包括一个应答机1,其特征在于,基于一种算法计算所存储的校验和,其中该算法对于一组应答机是相同的,并且与其他组应答机相比是不同的。
该识别系统包括通信器4,该通信器4连续地发送询问信号10。当应答机1在通信器4的附近时,通过应答机天线2接收信号10,并且该信号10接着被反射和调制为包含信息。此信息包括永久存储在应答机存储器3中的数据,特别是关于对象或个人的识别数据,以及同样永久存储在应答机1中的校验和。
与先前已知的技术相反,校验和已经被计算和存储在应答机1中,从而不需要在每一次要输出数据时进行计算。这提供了没有校验和计算电路的更简单的应答机1的优势。
在通信器4中从已经接收的数据计算校验和,并且该校验和在通信器4中与接收到的校验和进行比较。如果校验和彼此不一致,则认为错误地传送了该信息。如果校验和彼此一致,则认为全部传送信息已被正确地传送。
根据本发明的一个实施例,在通信器4中基于从应答机1传送的信息计算校验和,在计算中不包括所传送的校验和。根据本发明的另一个实施例,在通信器4中基于从应答机1传送的信息且基于从应答机1传送的校验和来计算校验和。因而,在后一个实施例中,在通信器4中的校验和计算包括从应答机1传送的校验和。
通过使用根据本发明的不同校验和计算算法,该系统可以适应于其中存在若干不同的授权级别的大公司或工厂中的应用,其中所述算法对存储在应答机1中的相同数据给出了不同校验和。当希望将该系统出售给若干互不相同的公司时,也可以应用此过程。
以下例子不意图限制本发明的范围,而是仅仅用来说明本发明的不同实施例。
根据本发明的第一具体实施例,要存储在应答机存储器中的信息是541 543 518,并且计算校验和的算法在于对所有数字求和。从而,校验和是36。在对应答机1编程时,该校验和被计算并且与信息541543 518一起被存储在应答机存储器3中。当应答机1在通信器4的附近时,应答机1将接收询问信号10,并且以调制的状态11反射此信号。在通信器4中接收并解释被反射和调制的信号11。在通信器4中基于已经从应答机1接收的除校验和之外的信息来计算校验和。在通信器4中比较所计算的校验和与所接收的校验和。当这些校验和不一致时,认为错误地传送了该信息。如果校验和彼此一致,则认为正确地传送了全部传送信息。
根据第二实施例,在公司安装的授权控制系统中的ID标签上使用应答机。每个单个雇员的号码与基于该单个雇员的号码计算出的校验和一起被存储在应答机1中。为了使得授权控制系统用于具有若干不同授权级别的公司中,用于计算校验和的算法对每个授权级别是不同的。因而,被提供了意图与给定算法共同执行功能的ID标签的一组雇员将具有对公司的特定部分的授权访问。在此实施例的情况下,该算法是这样的:前100个雇员号码将具有校验和s,并且其次100个雇员号码将具有校验和s+1,并且其次10个雇员号码将具有校验和s+3,其中s是雇员号码的数字的和。当读取存储在应答机1中的信息时,通信器4基于校验和并且借助数据系统9,确定相关的个人是否具有对一个部门的授权访问。
第三实施例描述了可以出售给大量互不相同的公司的授权控制系统。用于计算校验和的该算法对雇员号码中的所有数字求和。公司A具有1000个不同的雇员号码,这些雇员号码被划分为三(3)个授权级别。用于计算关于公司A的校验和的算法是这样的:这三个不同的雇员号码系列分别给出了校验和n+498 548 399,n+353 949 988和n+818 317 802,其中n是雇员号码中的数字的和。公司B具有100个不同雇员号码,这些雇员号码被划分为两(2)个授权级别。用于计算关于公司B的校验和的算法是这样的:用于两个授权级别的校验和分别是n+113 576 915和n+918 612 513,其中n是雇员号码中的数字的和。公司C具有6个雇员号码,这些雇员号码仅有一个授权级别。用于计算公司C的校验和的算法是这样的:校验和是n+361 711 918。选择一种算法用于计算一组雇员号码的校验和的可能性使得系统能够被出售给非常大量的公司,其中每个公司也可以具有若干不同的算法,以便使得能够包括若干授权级别。
根据第四实施例,要将一个识别系统出售给公司A。在公司A的多个雇员号码中具有三个雇员号码145 916、145 917以及145 918。用于计算公司A的校验和的算法对雇员号码中的数字求和,并且加上319 514。由上述雇员号码中的数字获得的校验和分别是26、27、和28。用于公司A的校验和因而分别是319 540、319 541、和319 542。此识别系统还将被出售给另一个公司,表示为公司B。公司B也具有雇员号码145 916、145 917以及145 918。用于计算公司B的算法对雇员号码中的数字求和,并且加上418 724。由上述雇员号码中的数字获得的校验和分别是26、27、和28。用于公司B的校验和因而分别是418 750、418 751、和418 752。此过程使得系统能够出售给很多公司,同时仍然保持安全性。
很明显,可以改变校验和与算法。本领域中的技术人员能够自由选择校验和与算法。
从而,由于可以在所附的权利要求的范围内做出变化,不应认为本发明被局限于上述示例性实施例中。
