为了更清楚地说明本发明的技术方案，下面将对实施方式中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

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。
请参阅图1，其是本发明实施例提供的一种智能书写方法的流程示意图。
所述智能书写方法包括：
S1，智能书写笔检测其与红外触摸屏之间的压力；
S2，所述智能书写笔通过设置在所述智能书写笔上的LED发射单元，向所述红外触摸屏发射信号强度随所述智能书写笔与所述红外触摸屏之间的压力变化的第一红外发射信号；
S3，所述红外触摸屏检测所述智能书写笔在所述红外触摸屏上产生的触摸轨迹；
S4，所述红外触摸屏接收所述第一红外发射信号所对应的第一红外接收信号；
S5，所述红外触摸屏根据预先配置的不同信号强度与笔迹显示状态的对应关系，确定所述第一红外接收信号的信号强度所对应的笔迹显示状态，作为所述智能书写笔的待配置笔迹显示状态；
S6，所述红外触摸屏显示与所述触摸轨迹对应的、具有所述待配置笔迹显示状态的笔迹。
在本发明实施例中，所述智能书写笔上设置有LED发射单元，且所述LED发射单元所发出的第一红外发射信号的信号强度随所述智能书写笔与所述红外触摸屏之间的压力变化；而所述红外触摸屏接收所述第一红外发射信号对应的第一红外接收信号，并根据所述第一红外接收信号的信号强度确定对应的笔迹显示状态，最终显示与所述触摸轨迹对应的、具有所述第一红外接收信号的信号强度所对应的笔迹显示状态的笔迹。因此，当所述智能书写笔与所述红外触摸屏之间的压力变化时，所述第一红外发射信号的信号强度相应变化，红外触摸屏接收到的第一红外接收信号的信号强度也相应变化，笔迹显示状态也会相应变化，实现了压感书写。由上可知，本发明根据所述智能书写笔与所述红外 触摸屏之间的压力大小来调节第一红外发射信号的信号强度，并根据检测到的所述第一红外接收信号的信号强度来实现对所述笔迹显示状态控制，智能书写笔无需将检测到的压力通过无线传输的方式发送给所述红外触摸屏，因此结构简单，生产成本低；而且本发明也不存在因为无线传输的延迟的现象而影响用户操作的问题，所以本发明的稳定性好，并具有良好的用户体验。
优选地，在步骤S3中，所述红外触摸屏检测所述智能书写笔在所述红外触摸屏上产生的触摸轨迹，包括：
所述红外触摸屏通过设置在所述红外触摸屏上的触摸屏发射灯发射第二红外发射信号，并通过设置在所述红外触摸屏上的触摸屏接收灯接收所述第二红外发射信号所对应的第二红外接收信号；
所述红外触摸屏根据所述第二红外发射信号以及所述第二红外接收信号获取所述智能书写笔在所述红外触摸屏上产生的触摸轨迹。
其中，所述红外触摸屏根据所述第二红外发射信号以及所述第二红外接收信号获取所述智能书写笔在所述红外触摸屏上产生的触摸轨迹的具体工作过程为：所述触摸屏发射灯分别设置在所述触摸屏的触摸框的相邻的两条侧框上，所述触摸屏接收灯分别设置在所述触摸屏的触摸框的另外两条侧框上，并组成一个发射和接收阵列；所述红外触摸屏控制触摸屏发射灯发出第二红外发射信号，并通过触摸屏接收灯接收相应的第二红外接收信号；当所述智能书写笔与所述红外触摸屏接触时，智能书写笔会遮挡住部分的光路，所述红外触摸屏因此能够根据第二红外发射信号与第二红外接收信号确定遮挡住光路的区域即智能书写笔在红外触摸屏的坐标位置。当所述智能书写笔在所述红外触摸屏上书写移动时，根据获取到的所述智能书写笔的各个时刻点的所述坐标位置就可以获取所述智能书写笔的触摸轨迹。
更优选地，所述LED发射单元设置在所述智能书写笔上的用于与所述红外触摸屏相接触的触摸部上；
所述红外触摸屏接收所述第一红外发射信号所对应的第一红外接收信号，具体为：所述红外触摸屏通过所述触摸屏接收灯接收所述第一红外发射信号所 对应的第一红外接收信号。
即在本发明实施例中，所述触摸屏接收灯同时用于接收所述第一红外接收信号与所述第二红外接收信号，而不用另外设置接收灯用于接收所述第一红外接收信号，节约了成本。
优选地，为了区分第一红外接收信号与第二红外接收信号，所述第一红外发射信号与所述第二红外发射信号的波长不同。
优选地，为了有效地遮挡住所述第一红外发射信号，所述触摸部采用不透光的材料制成。
更优选地，所述LED发射单元包括围绕所述触摸部设置的多个LED灯，保证了第一红外发射信号所对应的第一红外接收信号能够被触摸屏接收灯接收到。
更优选地，在步骤S2中，所述智能书写笔通过设置在所述智能书写笔上的LED发射单元，向所述红外触摸屏发射信号强度随所述智能书写笔与所述红外触摸屏之间的压力变化的第一红外发射信号，具体为：所述智能书写笔在所述智能书写笔与所述红外触摸屏之间的压力大于预设的压力阈值时，通过设置在所述智能书写笔上的LED发射单元向所述红外触摸屏发射信号强度随所述压力变化的第一红外发射信号。保证了智能书写笔只有在与红外触摸屏相接触时并且压力大于一定压力阈值时才会发射第一红外发射信号，避免了误判断。
优选地，所述笔迹显示状态包括笔迹属性以及所述笔迹属性所具有的属性数值。例如，所述笔迹属性为所述笔迹的线条宽度或颜色深度。可以理解的是，所述笔迹属性还可以为笔迹的颜色类型或者笔迹的线条形状等，在此不作具体限定。
在一个可选的实施方案中，所述第一红外发射信号的信号强度随所述智能书写笔与所述红外触摸屏之间的压力增大而增大；所述笔迹属性所具有的属性数值随所述第一红外接收信号的信号强度增大而增大。
在另一个可选的实施方案中，所述第一红外发射信号的信号强度随所述智能书写笔与所述红外触摸屏之间的压力增大而增大；所述笔迹属性所具有的属 性数值随所述第一红外接收信号的信号强度增大而增大。
在这两种实施方案中，最终的目的都是使得所述笔迹属性所具有的属性数值随所述智能书写笔与所述红外触摸屏之间的压力增大而增大。例如，压力越大时，线条宽度越宽或者颜色越深，实现了书写压感。
更优选地，所述第一红外接收信号的信号强度被划分为N个连续的信号强度区间，每个信号强度区间对应于所述笔迹属性的一个属性数值。例如，所述信号强度区间为四个，第一信号强度区间设为小于10％，第二信号强度区间设为10％～20％，第三信号强度区间设为20％～50％，第四信号强度区间设为大于50％，且所述属性数值为笔迹的宽度的数值；当第一红外接收信号的信号强度处于为第一信号强度区间时，对应的所述笔迹的宽度为0.1mm；当第一红外接收信号的信号强度处于为第二信号强度区间时，对应的所述笔迹的宽度为0.2mm，依次类推。因此，通过所述第一红外接收信号的信号强度的相应变化可以改变所述笔迹显示状态的所述属性数值，从而实现了所述笔迹显示状态的改变，丰富了所述笔迹的显示功能，从而提高了用户的体验。
