需要说明的是,在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
需要说明的是,本申请实施例中的智能卡的时序发光控制方法主要应用在控制发光智能 卡进行基于时序、时长、颜色、闪频及亮度等的发光控制场景中。
如图1所示,智能卡的时序发光控制方法主要包括以下步骤:

在本申请实施例中,智能卡中的控制电路包括满足基本读写功能的功能控制电控,和提供发光时序、时长、闪频、颜色及亮度等控制的时序控制电路。其中,功能控制电路与现有发光卡中的类似,不做详述,而时序控制电路作为时序发光控制中的重要环节,是本申请的核心技术所在。

S102,基于电能驱动智能卡中的时序控制电路输出时序逻辑控制数据。
可以理解的是,时序控制电路获得电能后,控制中心被激活,进而可以输出时序逻辑控制数据,控制智能卡中受控光源进行发光。优选的,时序逻辑控制数据为二进制的布尔值即“0”和“1”。其中,智能卡中的受控光源可以是图2中的LED,可以是多个也可以是一个。
另外,需要说明的是在基于电能驱动智能卡中的时序控制电路输出时序逻辑控制数据之前,可以根据二进制布尔值进行时序逻辑控制数据的预设。即根据实际的显示需求可以进行时序逻辑控制数据的预设,时序逻辑控制数据的预设与前述中的预设逻辑是对应的。实际应用中,时序逻辑控制数据是根据“每个受控光源的发光状态包括受控光源的发光时长、发光颜色、发光频率和发光亮度,每个受控光源的发光状态均由一组二进制的布尔值组成,所述时序逻辑控制数据由二进制布尔值组成的”的原理设置的。
S103,基于时序逻辑控制数据控制智能卡上受控光源的发光状态按时序变换。
在一种优选实现方式中,智能卡中受控光源的发光状态的发光时序以若干个时钟周期为 单位不断切换,在每个时钟周期内,智能卡中各受控光源的发光状态均可以对应一组布尔值。控制中心可以控制受控光源按照布尔值0和/或1组成的逻辑编码显示对应的发光状态。其中,受控光源的发光状态可以包括不同受控光源的发光时长、发光颜色、闪烁频率和发光亮度。发光状态与布尔值可以有如下对应关系:闪烁频率f1表示布尔值“1”,闪烁频率f2布尔值“0”;颜色c1表示布尔值“1”,闪烁频率c2布尔值“0”;颜色v1表示布尔值“1”,闪烁频率v2布尔值“0”。
进一步的,外设采集设备(如、光感应器或者摄像头)通过采集一个时钟周期内受控光源的发光状态,可以识别其对应的一组布尔值,该组布尔值可以代表特别的含义,例如,在某一时刻摄像头拍摄到智能卡中3颗发光光源中的其中一个发光而另外两个不亮,则这一组受控光源对应的逻辑控制数据的一组布尔值可以是1、0、0的任意组合(如,001、100、010)。由于各受控光源的闪烁频率不是同步的,各光源在同一时刻可能不会同时处于点亮状态,即在发光周期的不同发光时隙中,智能卡中各受控光源的发光状态可以是不同的。如图3a-图3d所示的智能卡,为星空背景智能卡,智能卡上线圈中的六颗“星星”被同时点亮后,以一定的频率闪烁,在四个不同时刻被点亮的星星不同,可以实现异步、时序控制的闪烁。图3a和图3c时刻6颗星均点亮,图3b均不亮,图3d有一颗被点亮。
需要说明的是,各受控光源在任一时钟周期内的发光状态可以组成一幅发光图案,不同图案可以代表不同的实际含义,如,图3a-图3d中的LED被点亮后组成漫天繁星的图案。
在本发明实施例中,通过利用天线感应智能卡读写器的电波获得电能,进而驱动智能卡利用时序发光控制电路进行时序发光的逻辑控制,实现了对智能卡中受控光源发光状态基于时序变换的发光控制,在保证发光智能卡原有数据读写功能的同时,增强了智能卡的数据显示功能。
另外,本发明实施例中通过时序逻辑控制的发光智能卡在工作过程中,当靠近读写器时感应天线产生电磁共振,天线产生电压,可以为功能控制电路、时序控制电路、多个发光器件(受控光源,LED)同时供电,在智能卡中的芯片工作时发光器件按照设定时序亮灭,向用户、光感应器、摄像头(外设采集设备)发送信息。
图4为本申请另一实施例提供的智能卡10的结构示意图,如图4所示,智能卡10可以包括电能获取模块101、控制数据输出模块102和发光时序控制模块103。
电能获取模块101,用于基于智能卡感应读写器发出的无线电波获取电能。
控制数据输出模块102,用于基于电能驱动智能卡中的时序控制电路输出时序逻辑控制数据。
发光时序控制模块103,用于基于时序逻辑控制数据控制智能卡上受控光源的发光状态按时序变换。
需要说明的是,智能卡10中的各功能模块的控制过程与上述方法实施例中的一致,可以参见上述方法实施例中的描述,此处不再赘述。
在本发明实施例中,通过利用天线感应智能卡读写器的电波获得电能,进而驱动智能卡利用时序发光控制电路进行时序发光的逻辑控制,实现了对智能卡中受控光源发光状态基于时序变换的发光控制,在保证发光智能卡原有数据读写功能的同时,增强了智能卡的数据显示功能。
图5为本申请又一实施例提供的智能卡内时序控制电路的结构示意图,如图5所示智能卡中时序控制电路可以包括时钟单元201、逻辑单元202、串行-并行转换单元203和数据译码单元204。通过上述四个单元可以实现对卡中各受控光源在固定时钟周期内实现特定规律的亮灭控制。需要说明的是,图5中各单元的内部元件连接关系放大后分别如图6、图7、图8和图9所示。
在图5所示的时序控制电路中,时钟单元201可以为逻辑单元202和串行-并行转换单元203提供时序时钟,逻辑单元202生成的串行数据输出至串行-并行转换单元203后转换为并行序列,该并行序列输入数据译码单元204译码为控制发光器件的数据流。需要说明的是,上述逻辑单元202可以是伪随机码生成单元。
需要说明的是,时钟单元201的实现受限于智能卡的能耗与体积,时钟电路被设计为带RC延迟的三非门环形振荡器。传统奇数非门环形振荡器振荡频率为:f=1/2×n×tpd。其中n为串联反相器的个数,tpd为传输延迟时间,实际应用中因tpd时间在几时到数百nS之间,故附件延迟环节,带延迟的三非门环形振荡器频率可由式子f=2.2×R1×C1计算,时钟单元201内各元件的连接关系如图6所示,其中R2位串联保护电阻。
进一步的,逻辑单元202即伪随机码生成单元可以由多级移位寄存器附加反馈端实现,图7为七级移位寄存器实现的伪随机码生成电路,对应的特征多项式f(x)=1+x^3+x^7,反馈系数取211,故序列为:010001001。
在一种实现方式中,串行-并行转换单元203可通过移位寄存器实现,如图8所示。可以理解的是,伪随机码生成单元202输出的伪随机码为串行数据,将伪随机码输出端后接移位寄存器配合数据译码器即可输出控制数据。其中数据译码器即为数据译码单元204。
本申请实施例中,数据译码单元204的内部电路是以8个发光光源即8个LED为例的,移位寄存器输出的三位并行数据经数据译码,可以对8LED进行控制,如图9所示。需要说明 的是,时序控制电路20中的串行-并行转换单元203和数据译码单元204中的元器件与受控光源数相关,即在实际应用中可以根据发光智能卡中LED的个数对具体的译码电路以及串行-并行电路进行调整。
在本实施例中,实现了一种智能卡中时序发光状态控制的时序控制电路,控制智能卡中受控光源的发光状态按预设的时序变换。在保证发光智能卡原有数据读写功能的同时,增强了智能卡的数据显示功能。

处理器301可以用于调用存储器302中存储的程序指令,并使智能卡30执行以下操作:

在一些实施例中,发光状态包括不同受控光源的发光时长、发光颜色、闪烁频率和发光亮度。
在一些实施例中,受控光源为一个或多个。
在一些实施例中,时序逻辑控制数据为二进制布尔值。
在一些实施例中,智能卡30还用于控制受控光源按照布尔值0和/或1组成的逻辑编码显示对应的发光时长、发光颜色、发光频率和发光亮度。
在一些实施例中,各受控光源任一时刻的发光状态对应一组布尔值。
在一些实施例中,各受控光源的发光状态共同组成一幅发光图案。
