图10是本发明实施例4提供的一种触摸控制装置的结构框图。
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，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本技术领域普通技术人员在没有作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。
参见图2所示，图2是本发明实施例1提供的一种触摸控制方法的方法流程图，所述触摸控制方法适用于n个触摸设备，n≥2，包括以下步骤：
S101、当任意时刻检测到对其中一触摸设备的down事件时，判断当前时刻是否存在其他触摸设备在上报触摸数据；
需要说明的是，对于触摸设备而言，每个触摸点，均有对应的down事件和up事件，其中，
down事件：手指或者笔，接触到触摸屏(包括红外屏、电容屏、电磁屏等)，由未接触到已接触的一瞬间所产生的事件，即为down事件；
up事件：对应的，手指或者笔，接触到触摸屏(包括红外屏、电容屏、电磁屏等)由已接触到离开触摸屏的一瞬间产生的事件，即为up事件。
对于安卓系统而言，每个触摸设备对存在对应的down事件和up事件,其中，down事件是指对于某一触摸设备由未接触到已接触的一瞬间所产生的事件；up 事件是指对于某一触摸设备由已接触到离开触摸屏的一瞬间产生的事件。本方案涉及到多触摸屏的数据上报问题，适用于对于上述对于安卓系统的情况。
当任意时刻检测到对其中一触摸设备的down事件时，且判断当前时刻不存在其他触摸设备在上报触摸数据，可直接相应改触摸设备的down事件，开始上报该触摸设备的触摸数据。
S102、若判断当前时刻存在其他触摸设备在上报触摸数据，获取所述其他触摸设备和当前触摸设备的响应优先级；其中，所述当前触摸设备为当前时刻检测到down事件的触摸设备；
其中，步骤S102中的响应优先级由用户或系统预先设置，可通过触摸设备类型、大小和型号等进行设置。当某一触摸设备的响应优先级更高时，需优先处理该触摸设备的触摸数据；当某一触摸设备的响应优先级更低时，需优先处理其他响应优先级更高的触摸设备的触摸数据。
S103、当所述其他触摸设备的响应优先级大于所述当前触摸设备的响应优先级时，则继续上报所述其他触摸设备的触摸数据直到检测到对所述其他触摸设备的up事件，并丢弃预设的第一时间段内所述当前触摸设备的触摸数据；其中，所述第一时间段为检测到所述当前触摸设备的down事件的时刻和检测到所述其他触摸设备的up事件的时刻之间的时间间隔；
S104、若所述其他触摸设备的优先级大于所述当前触摸设备，则当任意时刻检测到对其他触摸设备的up事件时，为当前触摸设备补down事件，并开始上报所述当前触摸设备的触摸数据。
下面以n＝2为例对上述过程进行详细说明。如图4所示，当系统在上报触摸设备1的触摸数据的过程中，若任意时刻检测到来源触摸设备2的down事件时，首先判断触摸设备1和触摸设备2的响应优先级。若触摸设备1的响应优先级大于触摸设备2的响应优先级，则在触摸设备1还没有up之前，先屏蔽触摸设备2的数据，如图4中虚线所示。例如，假设触摸设备1是红外触摸屏，触摸设备2是电磁触摸屏，在红外触摸屏的手势擦除过程中，在某一时刻感应到电磁触摸屏上电磁笔的书写操作，由于红外触摸屏的响应优先级大于电磁触 摸屏的响应优先级，因此需等待红外触摸屏的擦除动作完成，才能显示电磁触摸屏上的书写笔迹。
在另一优选实施例中，如图5所示，在实施例1的基础上，所述触摸控制方法还包括步骤：
S105、当所述其他触摸设备的响应优先级小于所述当前触摸设备的响应优先级时，则停止上报所述其他触摸设备的触摸数据，为所述其他触摸设备补up事件，并开始上报所述当前触摸设备的触摸数据直到检测到对所述当前触摸设备的up事件。
下面以n＝2为例对上述过程进行详细说明。如图6所示，当系统在上报触摸设备1的触摸数据的过程中，若任意时刻检测到来源触摸设备2的down事件时，首先判断触摸设备1和触摸设备2的响应优先级。若触摸设备1的响应优先级小于触摸设备2的响应优先级，则需要把触摸设备1补up事件，开始响应触摸设备2的触摸操作，且在触摸设备2工作过程中，将触摸设备1的触摸数据丢弃。例如，上述例子中，假设触摸设备1是红外触摸屏，触摸设备2是电磁触摸屏，在红外触摸屏的手势擦除过程中，在某一时刻感应到电磁触摸屏上电磁笔的书写操作，由于电磁触摸屏的响应优先级大于红外触摸屏的响应优先级，因此为红外触摸屏补up事件，停止响应红外触摸屏的擦除操作，开始在电磁触摸屏上显示电磁笔的书写笔迹。
如图7所示，驱动层USB控制中心和多点触摸接口之间加入了时序处理线程，该时序处理线程采用上述的触摸控制方法对触摸设备1和触摸设备2的触摸数据的上传顺序进行调整，避免出现两个触摸设备同时上报数据导致时序冲突，确保同一时刻只有一种触摸设备的触摸数据可以往上层上报。如图4所示，当触摸设备1的所有触摸点up之后，可正常响应触摸设备2的触摸操作，不会影响触摸设备2在Android上层的状态，满足Android框架下多触摸设备的兼容性问题。
参见图8，为本发明实施例3提供的一种触摸控制方法的流程图
S201、当任意时刻检测到对其中一触摸设备的down事件时，判断当前时刻 是否存在其他触摸设备在上报触摸数据；
S202、若判断当前时刻存在其他触摸设备在上报触摸数据，获取所述其他触摸设备和当前触摸设备的响应优先级；其中，所述当前触摸设备为当前时刻检测到down事件的触摸设备；
S203、当所述其他触摸设备的响应优先级大于所述当前触摸设备的响应优先级时，则继续上报所述其他触摸设备的触摸数据直到检测到对所述其他触摸设备的up事件，并丢弃预设的第一时间段内所述当前触摸设备的触摸数据；其中，所述第一时间段为检测到所述当前触摸设备的down事件的时刻和检测到所述其他触摸设备的up事件的时刻之间的时间间隔；
S204、当所述其他触摸设备的响应优先级大于所述当前触摸设备的响应优先级时，将所述当前触摸设备添加至补down事件列表中；
S205、若所述其他触摸设备的优先级大于所述当前触摸设备，则当任意时刻检测到对其他触摸设备的up事件时，判断所述补down事件列表中的触摸设备的数量是否等于1；
S206、若所述补down事件列表中的触摸设备的数量等于1，则为所述当前触摸设备补down事件，开始上报所述当前触摸设备的触摸数据，为并将所述当前触摸设备在所述补down事件列表中删除。
也就是说，只有在所述补down事件列表中的触摸设备的数量等于1的情况下，才无需确定先为那个触摸设备补down事件，仅需响应剩余的一个触摸设备的触摸数据。上述可存在两种情况，一种为n＝2的情况，另一种为在补down事件列表中的触摸设备已经提前up了，这种情况也会将其在所述补down事件列表中删除。
而另外的一种情况是，若所述补down事件列表中的触摸设备的数量大于1时，根据所述补down事件列表中所述触摸设备的响应优先级，对所述触摸设备进行排序生成响应序列；根据所述响应序列，从所述响应序列中的第一个触摸设备开始，依次上报每一触摸设备的触摸数据。
优选地，如图9所示，可采用以下方式依次上报每一触摸设备的触摸数据：
S301、开始上报所述第一个触摸设备的触摸数据直到检测到所述第一个触摸设备的up事件；
S302、当任意时刻检测所述第一个触摸设备的up事件时，为所述响应列表中的下一个触摸设备补down事件，并将所述第一个触摸设备在所述补down事件列表中删除；
S303、响应于任意时刻对所述响应序列中其中一触摸设备的down事件，开始上报所述触摸设备的触摸数据直到检测到所述触摸设备的up事件，将所述触摸设备从所述响应序列中删除，并丢弃预设的第二时间段内所述响应序列中的剩余触摸设备的触摸数据；其中，所述第二时间段为检测到所述触摸设备的down事件的时刻和检测到所述触摸设备的up事件的时刻之间的时间间隔；
S304、当任意时刻检测所述触摸设备的up事件时，为所述响应列表中的下一个触摸设备补down事件，并将所述当前触摸设备在所述补down事件列表中删除。
此外，还存在一种情况为同一时刻检测到多个触摸设备的down事件，可将所述多个触摸设备添加至所述补down事件列表中，根据所述补down事件列表中所述触摸设备的响应优先级，对所述多个触摸设备进行排序生成响应序列，然后根据所述响应序列，从所述响应序列中的第一个触摸设备开始，依次上报每一触摸设备的触摸数据。优选地，可采用如图9所示的方法依次上报每一触摸设备的触摸数据。
