具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例只是本发明中一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面通过具体实施方式结合附图对本发明作进一步详细说明。
为实现本发明提供的外设在电容触屏上的定位方法，本发明首先提供一种外设，如图1所示，该外设包括壳体1及通信模块2，该通信模块2用于与带有电容触屏的触控设备进行通信，还包括触发器3，该触发器3设置于该外设的壳体1内或壳体1上，当外设需要和触控设备进行通信时，将该外设靠近或接触触控设备的电容触屏，即触发器3靠近或接触触控设备的电容触屏，该触发器3则触发产生电信号信息，该电信号信息可以产生于触控设备的电容触屏上，也可以产生于该外设上。该触控设备包括但不局限于智能手机、平板电脑、超级本或个人数字助理等带有电容触屏的电子设备，该外设包括但不局限于U盾、智能卡或其它可以和触控设备通信的电子设备。
如图2为本发明另一实施例提供的外设的结构示意图，如图2所示，该触发器3为设置于该壳体1上的导体，由于该导体具有导电性能，故在外设靠近或接触触控设备的电容触屏时，即该导体靠近或接触触控设备的电容触屏，通过该导体使得在电容触屏上与该外设的接触点或接触区域产生了明显的电容变化，即该导体因靠近或接触触控设备的电容触屏中至少 一个区域而使电容触屏发生电容变化，进而产生电容值变化量信息组，该电容值变化量信息组包括了电容触屏上至少一个各个区域内的电容值变化量。
在上述技术方案中，由于该导体设置于壳体1上，故对于该导体与壳体1之间的设置关系，该导体可以与壳体1一体成型，例如，该导体为具有导电性能的金属外壳、导电材料外壳等，且在外设靠近或接触触控设备的电容触屏时，即该导体靠近或接触电容触屏，从而可触发电容触屏中至少一个区域产生电容值变化量信息组，需要说明的是，对于该外设的壳体1，其各个面均可以为上述导体，也可以是其各个面中的部分面为上述导体，其他面为非上述导体；此外，该导体还可以覆盖于壳体1的至少一个外表面上，例如，在非导电外壳上的至少一面上附加一层导电层，该导电层通常覆盖于非导电外壳的外表面上，且在外设靠近或接触触控设备的触控设备时，即该导体靠近或接触触控设备的电容触屏，从而可触发电容触屏中至少一个区域产生电容值变化量信息组。
在本实施例中，当上述外设靠近或接触触控设备的电容触屏时，即该导体靠近或接触触控设备的电容触屏，通过该导体使得在电容触屏上与外设的靠近点、接触点或靠近区域、接触区域产生了较为明显的电容变化，触控设备可获取因电容触屏发生电容变化而产生的电容值变化量信息组，根据该电容值变化量信息组，即可确定外设在电容触屏上靠近或接触的区域，从而完成对外设的定位，保证触控设备与外设之间位置的放置准确。
如图3为本发明另一实施例提供的外设的结构示意图，如图3所示， 该触发器3为可产生磁场的磁性器件，由于该磁性器件可产生磁场，且在触控设备的电容触屏中存在金属扫描线，故在外设靠近或接触触控设备的电容触屏时，即该磁性器件靠近或接触触控设备的电容触屏，电容触屏中的金属扫描线切割磁力线，该磁性器件因靠近或接触电容触屏而使电容触屏中至少一个区域发生电磁感应，进而产生感应电流变化量信息组，该感应电流变化量信息组包括了电容触屏上至少一个区域的感应电流变化量。
在上述技术方案中，对于磁性器件的设置位置，可设置于壳体1内，且靠近该壳体1的至少一个内表面，可以使得该磁性器件为一个连续的平面区域，此外，还可在该壳体1内某个固定区域或几个区域安装该磁性器件，即该磁性器件在壳体1内的排布可以为矩形、三角形、圆形或多边形等，且在实际设计中，该磁性器件的数量可以根据定位需要而设计，优选地，为了使外设与触控设备的定位条件具有唯一性，在确定磁性器件数量及排布的过程中，可以选择三个磁性器件，这三个磁性器件的排布为除等边三角形之外的任意三角形，从而可以防止外设上下或左右翻转时不能区分其位置。对于安装有磁性器件的外设，其外壳可以为如实施例一中的外壳，也可以为非导电材料外壳或绝缘材料外壳，例如塑料、玻璃、PVC(Polyvinyl chloride polymer，聚氯乙烯)等材质的外壳。
在本实施例中，由于磁场主要分为静态磁场和动态磁场，因此，当该磁性器件为可产生静态磁场的磁性器件时，例如带有磁性的磁铁、磁性材料或可产生静态磁场的感应线圈，当上述外设靠近触控设备的电容触屏时，即该磁性器件靠近或接触触控设备的电容触屏，由于外设和电容触屏之间 存在相对运动，电容触屏内部的金属扫描线将切割磁力线，进而在电容触屏内部的金属扫描线内产生感应电流，即通过静态磁场的移动可触发电容触屏发生电磁感应，进而产生感应电流；当该磁性器件为可产生动态磁场的磁性器件时，例如可产生动态磁场的感应线圈，当上述外设靠近或接触触控设备的电容触屏时，即该磁性器件靠近或接触触控设备的电容触屏，由于外设内部设置有可产生动态磁场的感应线圈，其可以产生动态磁场，而该动态磁场并不需要外设和电容触屏之间存在相对运动，故同样在电容触屏内部的金属扫描线内产生感应电流，即通过动态磁场可触发电容触屏发生电磁感应，进而产生感应电流，综上，无论是静态磁场，还是动态磁场，触控设备可获取因电容触屏至少一个区域发生电磁感应而产生的感应电流变化量信息组，根据该感应电流变化量信息组，即可确定外设在电容触屏上靠近或接触的区域，从而完成对外设的定位，保证触控设备与外设之间位置的放置准确。
如图4为本发明另一实施例提供的外设的结构示意图，如图4所示，该触发器3为光电感应器件，由于该光电感应器件可产生光电感应，在外设靠近或接触触控设备的电容触屏之前，触控设备可按照外设所设计的光电感应器件的安装位置，通过软件控制其电容触屏上的某些特点区域或某些特定点发亮而其余区域或其余点无亮度，该亮度用于和外设的光电感应器件进行位置辨认，当外设靠近或接触触控设备的电容触屏时，即光电感应器件靠近或接触电容触屏时，由于电容触屏上存在发光区域或发光点，只有当外设的光电感应器件对准电容触屏上的特定发光区域或特定发光点 时，才能转换为有效的光电感应信号，该光电感应信号可以是电压信号，也可以是电流信号，即该光电感应器件因靠近或接触电容触屏的发光区域或发光点而使光电感应器件发生光电感应，进而产生光电感应信号。该光电感应器件包括但不局限于光电二极管、光敏电阻或其他类型的光电感应材料。
在上述技术方案中，对于光电感应器件的设置位置，可根据实际需求进行设置，例如将光电感应器件设置于该壳体1的外表面上，且保证是在同一外表面上，优选地，为了方便定位，该光电感应器件可安装于壳体的底面上，该光电感应器件在壳体1外表面上的排布可以为矩形、三角形、圆形或多边形等，且在实际设计中，光电感应器件的数量可以根据定位需要而设计，优选地，为了使外设与触控设备的定位条件具有唯一性，在确定光电感应器件数量及排布的过程中，可以选择三个光电感应器件，这三个光电感应器件的排布为除等边三角形之外的任意三角形，从而可以防止外设上下或左右翻转时不能区分其位置。对于安装有光电感应器件的外设，其外壳可以为如实施例一中的外壳，也可以为非导电材料外壳或绝缘材料外壳，例如塑料、玻璃、PVC(Polyvinyl chloride polymer，聚氯乙烯)等材质的外壳。
在本实施例中，当上述外设靠近或接触触控设备的电容触屏时，由于电容触屏上发光区域或发光点的存在，使得只有上述光电感应器件在对准电容触屏上的发光区域或发光点时，才能转换为有效的光电感应信号，外设获取因该动作引发光电转换而产生的光电感应信号，根据该光电感应信 息，即可确定外设在电容触屏上靠近或接触的区域，从而完成对外设的定位，保证触控设备与外设之间位置的放置准确。
实施例一：
如图5为本发明实施例一提供的外设在电容触屏上的定位方法的流程图，如图5所示，该外设在电容触屏上的定位方法包括：
S101：判断是否发生外设靠近或接触电容触屏的动作；
具体地，当外设需要和触控设备进行通信时，将该外设靠近或接触触控设备的电容触屏，因此，为了使触控设备与外设之间的相对位置放置准确，需对外设进行定位，则判断是否发生外设靠近或接触电容触屏的动作，该判断过程可以由触控设备完成，也可以由外设完成。该触控设备设置有电容触屏，其包括但不局限于智能手机、平板电脑、超级本或个人数字助理等电子设备，该外设包括但不局限于U盾、智能卡或其它可以和触控设备通信的电子设备。
S102：当判断为发生动作时，获取因动作产生的电信号信息；
具体地，当判断为发生外设靠近或接触电容触屏的动作时，由于该动作，使得触控设备或外设产生了电信号信息，从而获取因该动作产生的电信号信息，针对该电信号信息，其获取方式包括但不局限于以下方式：
方式一、获取因动作引发电容触屏中至少一个区域发生电容变化而产生的电容值变化量信息组；
若该外设为具有导电性能的金属外壳、导电材料外壳或在绝缘材料外壳上附加一层导电层的电子设备，当外设靠近或接触触控设备的电容触屏时，由于外设为具有导电性能的金属外壳、导电材料外壳或导电层的电子设备，导致在电容触屏上与外设的靠近点、接触点或靠近区域、接触区域产生了明显的电容变化，触控设备可获取因该动作引发电容触屏中至少一个区域发生电容变化而产生的电容值变化量信息组，即该电容值变化量信息组包括了电容触屏上至少一个区域内的电容值变化量；
方式二、获取因动作引发电容触屏中至少一个区域切割磁力线而产生的感应电流变化量信息组；
若该外设为非导电材料外壳或绝缘材料外壳的电子设备时，例如塑料、 玻璃、PVC(Polyvinyl chloride polymer，聚氯乙烯)等材质，由于非导电材料外壳或绝缘材料外壳对电容触屏的电容变化改变很小，就目前的技术条件而言，电容触屏很难通过电容值变化量对外设进行定位，因此，可在该具有非导电材料外壳或绝缘材料外壳的外设内部一个固定区域或几个区域安装磁性器件，当然，也不排除在具有导电性能的金属外壳、导电材料外壳或在绝缘材料外壳上附加一层导电层的外设内部一个固定区域或几个区域安装磁性器件，在实际设计中，该磁性器件的数量可以根据定位需要而设计，如该磁性器件可以是一个连续的平面区域，该磁性器件可产生磁场，由于磁场主要分为静态磁场和动态磁场，因此，当该磁性器件为可产生静态磁场的磁性器件时，例如带有磁性的磁铁、磁性材料或可产生静态磁场的感应线圈等，当外设靠近触控设备的电容触屏时，由于外设和电容触屏之间存在相对运动，电容触屏内部的金属扫描线将切割磁力线，即通过上述可产生静态磁场的磁性器件可触发电容触屏发生电磁感应，进而在电容触屏内部的金属扫描线内产生感应电流，当该磁性器件为可产生动态磁场的磁性器件时，例如可产生动态磁场的感应线圈，当外设靠近或接触触控设备的电容触屏时，由于外设内部设置有可产生动态磁场的感应线圈，其可以产生动态磁场，而该动态磁场并不需要外设和电容触屏之间存在相对运动，故同样在电容触屏内部的金属扫描线内产生感应电流，触控设备可获取因动作引发电容触屏中至少一个区域切割磁力线而产生的感应电流变化量信息组，即该感应电流变化量包括了电容触屏上至少一个区域内的感应电流变化量；
方式三、获取因动作引发光电转换而产生的光电感应信号。
当外设为具有非导电材料外壳或绝缘材料外壳的电子设备时，例如塑料、玻璃、PVC等材质，由于非导电材料外壳或绝缘材料外壳对电容触屏的电容变化改变很小，就目前的技术条件而言，电容触屏很难通过电容值变化量对外设进行定位，因此，可在该具有非导电材料外壳或绝缘材料外壳上安装光电感应器件，当然，也不排除在具有导电性能的金属外壳、导电材料外壳或在绝缘材料外壳上附加一层导电层的外设壳体上光电感应器件，该光电感应器件包括但不局限于光电二极管、光敏电阻或其他类型的光电感应材料，优选地，为了方便定位，该光电感应器件可安装于外设的底部，在实际设计中，光电感应器件的数量可以根据定位需要而设计，当外设靠近电容触屏时，可按照外设所设计的光电感应器件的安装位置，触 控设备通过软件控制其电容触屏上的某些特定区域或某些特定点发亮而其余区域或其余点无亮度，该亮度用于和外设内部的光电感应器件进行位置辨认，当外设的底部与电容触屏之间相互接触时，只有当外设底部的光电感应器件对准电容触屏上的特定发光区域或特定发光点时，才能转换为有效的光电感应信号，该光电感应信号可以是电压信号，也可以是电流信号，外设获取因该动作引发光电转换而产生的光电感应信号。
S103：根据电信号信息，确定外设在电容触屏上靠近或接触的区域。
具体地，当获取到因动作产生的电信号信息时，即可根据该电信号信息，确定外设在电容触屏上靠近或接触的区域，从而迅速完成对外设的定位，使得触控设备能够更好地与外设进行通信。
在本实施例中，确定外设在电容触屏上靠近或接触的区域的方式，包括但不局限于以下方式：
方式一、当获取因动作引发电容触屏中至少一个区域发生电容变化而产生的电容值变化量信息组时，根据电容触屏上至少一个区域内的电容值变化量，获取该电容值变化量信息组中电容值变化量相对较大对应的区域，即在电容触屏上的某个区域处，若其电容值变化量相对较大，则将该电容值变化量相对较大对应的区域确定为外设在电容触屏上靠近或接触的区域；
方式二、当获取因动作引发电容触屏中至少一个区域切割磁力线而产生的感应电流变化量信息组时，根据电容触屏上至少一个区域内的感应电流变化量，获取该感应电流变化量信息组中感应电流变化量相对较大对应的区域，即在电容触屏上的某个区域处，若其感应电流变化量相对较大，则将该感应电流变化量相对较大对应的区域确定为外设在电容触屏上靠近或接触的区域；
方式三、当获取因动作引发光电转换而产生的光电感应信号时，判断该光电感应信号是否超过设定阈值，只有当外设的光电感应器件对准电容触屏上的特定发光区域或特定发光点时，光电感应信号即可超过设定阈值，即可获取外设的当前位置，将外设的当前位置确定为外设在电容触屏上靠近或接触的区域。
