Description
技术领域
本发明提供一种探测系统,涉及射频识别技术、导电浆料印刷、电容耦合技术。
背景技术
在探测一个被探测物时,需要通过电容耦合方式,使用触摸电极感应到探测物的存在,通过射频识别天线读取被探测物内置的射频标签,从而实现对被探测物的触摸和射频的双重识别。
实现对被探测物的触摸和射频的双重识别的现有技术比较少。根据现有技术,触摸电极使用金属或者氧化铟锡(ITO)材料,触摸电极和射频识别天线往往是上下两层平行布置,相互之间有双向信号干扰。射频天线发出的无线信号对触摸电极的干扰,会导致触摸电极的信号基线噪声很大,降低触摸电极对被探测物的探测的灵敏度。触摸电极同时会对射频天线的无线信号产生干扰和屏蔽,降低射频天线的读取射频标签的能力。
常用电磁屏蔽技术不适用,因为射频无线信号和触摸电极的电场信号需要在空间叠加,达到对被探测物的双重探测、识别。
据此,有必要发明一种新的系统与方法,可以针对一个被探测物、降低电容感应和射频识别的双向干扰,更好的实现电容感应和射频标识的双重识别。

我们的试验结果表明,使用方阻适中,例如方阻在40Ω/□与350Ω/□之间的导电浆料,所生成的触摸电极仍然可以保持电容感应的良好性能;同时,使用这种导电浆料生成的触摸电极和射频天线的双层结构,电容感应和射频识别的双向干扰极大的降低。
据此,本发明提供一种探测系统,包括:处理器;触摸电极,由导电浆料制成,经电容耦合模块连接到所述处理器;射频天线,位于所述触摸电极下一层,经射频探测模块连接到所述处理器;被探测物,位于所述触摸电极上一层,所述被探测物内置有射频识别标签;其中,当所述被探测物进入所述触摸电极的探测范围时,所述处理器经所述触摸电极靠电容耦合作用探测到所述被探测物;所述射频天线发出或接收的无线信号,穿过所述导电浆料制成的所述触摸电极,探测到所述被探测物内置的所述射频识别标签;所述射频探测模块把所述射频天线探测的信息传给所述处理器。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。
本发明提供一种探测系统,用于探测被探测物1,如图 1所示,包括:处理器6;触摸电极4,由导电浆料制成,经电容耦合模块5连接到处理器6;射频天线3,位于触摸电极4下一层,经射频探测模块7连接到处理器6;被探测物1,位于触摸电极4上一层,被探测物1内置有射频识别标签8。当被探测物1进入触摸电极4的探测范围时,处理器6经触摸电极4靠电容耦合作用探测到被探测物1;射频天线3发出或接收的无线信号,穿过所述导电浆料制成的触摸电极4,探测到被探测物1内置的射频识别标签8;射频探测模块7把射频天线3探测的信息传给处理器6。
导电浆料,可选用一种碳油墨,经印刷涂敷在一个基板上,固化后方阻为40~350Ω/□,经基板上的通孔连接到电容耦合模块5。
在射频天线3处于开通、读取被探测物1的状态下,处理器6经触摸电极4靠电容耦合作用探测到被探测物1。射频天线3有三种状态:(1)断电;(2)开通、不读取被探测物1;(3)开通、读取被探测物1。射频天线3处于开通、读取被探测物1的状态下,射频天线3通电,射频识别标签8进入射频场后,射频天线3获得感应电流。
在触摸电极4处于开通、与所述被探测物1进行电容耦合的状态下,处理器6经射频天线3探测到被探测物1内的射频识别标签8。触摸电极4有三种状态:(1)断电;(2)开通、不与被探测物1进行电容耦合;(3)开通、与被探测物1进行电容耦合。触摸电极4处于开通、与被探测物1进行电容耦合的状态下,触摸电极4通电,并进行充电放电。
如 图 2所示,导电浆料制成的多个触摸电极4排布成电极阵列;被探测物1位于电极阵列上一层;当被探测物1进入射频天线3的探测范围时,射频天线3发出或接收的无线信号,穿过所述导电浆料制成的所述电极阵列,探测到被探测物1内的射频识别标签8。
如 图 3所示,当射频天线3为多个时,排布成天线阵列,位于电极阵列下一层。当被探测物1进入所述天线阵列的探测范围时,所述天线阵列发出或接收的无线信号,穿过所述导电浆料制成的所述电极阵列,探测到被探测物1内的射频识别标签8。
被探测物1位于交互面上;电极阵列安装在交互面的第一层;天线阵列位于电极阵列下一层,安装在交互面的第二层;电容耦合模块5、处理器6和射频探测模块7安装在交互面的底座2上。
经实测,使用碳油墨做成的触摸电极4后,射频天线3对射频识别标签8的识别率,相比铜皮或者氧化铟锡(ITO)做成的触摸电极4而言,要高得多。因此,射频无线信号被触摸电极4吸收的程度降低了很多,亦即干扰降低了、信噪比提升了、射频信号通过率提升了。实测结果如图 5和图 4,都是在被探测物1没有放上电极阵列时所测得的许多个触摸电极4所发生的耦合电容值的上下跳动幅度,形成了带状的基线。其中纵轴为耦合电容值,横轴为毫秒。每11毫秒测取一个耦合电容值点,共测取2800个点。
见图 4,当触摸电极4是ITO薄膜时,耦合电容值跳动幅度为34570~35070,最大差值将近500。这些跳点可能导致触摸电极的误触发。
见图 5,当触摸电极4是碳油墨时,耦合电容值跳动幅度为20106~20140,最大差值为34。
耦合电容值跳动幅度越小,则基线越窄,信噪比越高。
依照本发明的方案,其探测方法如下:
当被探测物1进入触摸电极4的探测范围时,处理器6经触摸电极4靠电容耦合作用探测到被探测物1;
射频天线3发出或接收的无线信号,穿过所述导电浆料制成的触摸电极4,探测到被探测物1内置的射频识别标签8;
射频探测模块7把射频天线3探测的信息传给处理器6。
在射频天线3处于开通、读取被探测物1的状态下,处理器6经触摸电极4靠电容耦合作用探测到被探测物1。
在触摸电极4处于开通、与所述被探测物1进行电容耦合的状态下,处理器6经射频天线3探测到被探测物1内的射频识别标签8。
当被探测物1进入射频天线3的探测范围时,射频天线3发出或接收的无线信号,穿过所述导电浆料制成的所述电极阵列,探测到被探测物1内的射频识别标签8。其中,导电浆料制成的多个触摸电极4排布成电极阵列;被探测物1位于电极阵列上一层。
当被探测物1进入所述天线阵列的探测范围时,所述天线阵列发出或接收的无线信号,穿过所述导电浆料制成的所述电极阵列,探测到被探测物1内的射频识别标签8。其中,射频天线3为多个,排布成天线阵列,位于电极阵列下一层。
最后应说明的是:以上各实施例仅用以说明本发明的技术方案,而非对其限制;尽管参照前述各实施例对本发明进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分或者全部技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
