需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚 地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
实施例1
根据本申请实施例，提供了一种交互智能设备的控制方法的实施例，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本实施例的下述步骤可以由交互智能设备执行，图1是根据申请实施例的一种交互智能设备的控制方法的流程图，如图1所示，该方法包括如下步骤：
步骤S102，接收电磁笔发出的书写参数选择信号，其中，电磁笔根据接收到的控制信息确定书写参数选择信号的信号频率。
具体的，上述书写参数用于确定笔迹所展示的形态，包括笔迹的颜色、笔迹的类型等，书写参数选择信号在书写前接收，用于在书写前，确定书写参数。
电磁笔接收到的控制信息可以由用户对电磁笔进行操作发出，在一种可选的实施例中，电磁笔表面包括按键、或档位等控制控件，用户可以通过操作上述控制控件来选择书写参数选择信号的信号频率。
步骤S104，根据书写参数选择信号的信号频率确定书写参数。
具体的，上述书写参数包括：书写颜色和书写笔迹的类型。上述书写颜色用于表示生成的笔迹的颜色，书写笔迹的类型可以包括笔迹的粗细、笔迹的线性等。
交互智能设备在接收到书写参数选择信号后，根据书写参数选择信号的信号频率确定书写参数。
在一种可选的实施例中，以书写参数选择信号为悬浮电磁信号为例，电磁笔上可以设置有选择开关，不同选择开关对应不同频率的悬浮电磁信号，其中，每种频率的悬浮电磁信号对应一组书写参数，用户将选择开关调整至对应的位置，当电磁笔接近电磁屏，进入电磁屏的有效控制区域时，电磁屏接收到用户所选的频率的悬浮电磁信号，交互智能设备基于频率和书写参数的关系，即可确定书写参数。
步骤S106，接收电磁笔发出的书写信号，并根据书写信号生成与书写参数对应的笔迹。
具体的，上述书写信号由发送书写参数选择信号的电磁笔接触电磁屏时发出，作 为一种可选的实施例，上述书写信号为电磁笔发出的笔压电磁信号。
在上述方案中，用户使用电磁笔接触电磁屏后进行书写，书写出的笔迹与步骤S104中确定的书写参数相匹配。
在一种可选的实施例中，用户通过设置在电磁笔表面的选择开关，确定了输出的悬浮电磁信号的频率，用户拿起电磁笔靠近电磁屏进行书写，在电磁笔靠近电磁屏的过程中，首先进入电磁屏的有效控制区域，电磁笔发出与用户所选的频率对应的悬浮电磁信号。电磁屏接收到该频率的悬浮电磁信号，根据悬浮电磁信号的频率确定一组书写参数，其中，一组书写参数中可以包括多种书写参数，例如：书写颜色、笔迹类型等。当用户使用电磁笔接触电磁屏开始书写时，交互智能设备已经根据书写参数选择信号确定了书写参数，交互智能设备根据用户书写的轨迹，结合已确定书写参数，生成的笔迹即可。
当用户需要更换书写参数时，用户使电磁笔脱离电磁屏表面，通过调整上述选择开关来调整书写参数选择信号的信号频率，从而更改书写参数，当用户再次使用电磁笔接触到电磁屏进行书写时，交互智能设备生成的笔迹为更改后的书写参数。
尤其在用户的书写需要频繁的在多种类型的书写参数中切换时，上述实施例提供的方法为用户的书写提供了极大的遍历。
由上可知，本申请上述实施例，接收电磁笔发出的书写参数选择信号，其中，电磁笔根据接收到的控制信息确定书写参数选择信号的信号频率，根据书写参数选择信号的信号频率确定书写参数，接收电磁笔发出的书写信号，并根据书写信号生成与书写参数对应的笔迹。上述方案中，由电磁笔发出书写参数选择信号，从而使得需要更换书写的颜色或笔迹类型时，无需手动操作交互智能设备上的控件，仅需向电磁笔发出控制信息即可，进而提高了用户使用电磁笔书写时的便捷性，解决了现有技术中更换电磁笔书写的颜色或书写类型时需要手动对书写软件进行控制，导致操作繁琐的技术问题。
作为一种可选的实施例，书写参数选择信号为悬浮电磁信号，书写参数选择信号在电磁笔处于交互智能设备的电磁屏的预设有效控制范围内，且未与电磁屏接触时发出。
电磁屏的预设有效控制范围是根据电磁屏的类型，以及书写参数选择信号的类型确定的，如果该书写参数选择信号为电磁信号，则有效控制范围可以是距离电磁屏5-30mm之内的范围，电磁笔与电磁屏之间的距离可以为电磁笔的笔尖到电磁屏之间的距离。
而如果电磁笔接触到电磁屏后，则会生成书写笔迹，因此书写参数选择信号是在 电磁笔处于电磁屏的预设有效控制范围内，但未接触电磁屏时发出的。
在上述方案中，当电磁笔接进入电磁屏的有效控制范围，但并未与电磁屏接触时，电磁屏仅能检测到电磁笔发出的书写参数选择信号，当电磁笔的笔尖接触到电磁屏时，电磁屏既能检测到书写参数选择信号，也能检测到书写信号，在这种情况下，交互智能设备以书写信号优先，生成书写信号对应的笔迹。
作为一种可选的实施例，接收电磁笔发出的书写参数选择信号，包括：检测预设有效控制范围内的悬浮电磁信号；如果检测到悬浮电磁信号，则确定接收到书写参数选择信号。
在一种可选的实施例中，当电磁笔进入电磁屏的有效控制范围时，电磁笔的悬浮电磁线圈即会发出悬浮电磁信号，交互智能设备检测到该悬浮电磁信号时，从而确定接收到书写参数选择信号。
作为一种可选的实施例，根据书写参数选择信号的信号频率确定书写参数，包括：检测书写参数选择信号的信号频率；获取预设的信号频率与书写参数的对应关系；根据书写参数选择信号的信号频率在对应关系中查找与书写参数选择信号对应的书写参数。
具体的，可以预设书写参数选择信号的信号频率与书写参数的对应关系，并将对应关系存储至交互智能设备中。当交互智能设备检测到书写参数选择信号后，在对应关系中查找与该书写参数选择信号的信号频率对应的书写参数，从而确定当前的书写参数。
在一种可选的实施例中，交互智能设备还可以提供设置信号频率与书写参数的对应关系的控制界面，由用户根据使用习惯设置不同信号频率对应的书写参数。图3是根据本申请实施例的一种调整信号频率与书写参数的对应关系的示意图，结合图3所示，档位1、档位2和档位3分别表示三种不同频率的书写参数选择信号，用于可以选择每个档位对应的笔迹颜色和笔迹类型，从而对不同信号频率对应的书写参数进行设置。
作为一种可选的实施例，书写信号为电磁笔中的笔压线圈生成的笔压电磁信号，笔压电磁信号的信号频率与书写参数选择信号的信号频率不同。
由于书写信号与书写参数选择信号均为电磁信号，因此为了使交互智能设备区分这两种信号，将书写信号与书写参数选择信号设置为不同的信号频率。
图2是根据本申请实施例的一种交互智能设备的控制原理图，在该示例中，以电磁屏在白板应用上书写为例进行说明，结合图2所示，首先，在电磁笔的电磁笔电路 单元中，包括两个互相独立的线圈，一个是用于生成电磁悬浮信号的线圈(即图中的线圈1)，一个是用于生成笔压电磁信号的线圈(即图中的线圈2)，这两个线圈分别独立设置。
其中，线圈1包括3个部分，分别用于生成信号频率不同的电磁笔悬浮信号1、电磁笔悬浮信号2以及电磁笔悬浮信号3，电磁笔上还设置有悬浮信号选择开关，悬浮信号选择开关用于根据不同的档位控制线圈1的绕组，从而在电磁笔悬浮信号1、电磁笔悬浮信号2以及电磁笔悬浮信号3中选择电磁笔输出的电磁笔悬浮信号。
当电磁笔进入电磁屏的控制范围后，电磁笔发出电磁笔悬浮信号，交互智能设备的电磁天线接收到电磁笔悬浮信号，将电磁笔悬浮信号发送至电磁控制单元进行数据处理，电磁控制单元进行判断及控制，根据电磁笔悬浮信号的频率确定书写参数，并控制白板软件后台自动切换书写参数。
随着电磁笔继续靠近电磁屏，电磁笔与电磁屏接触，此时电磁笔通过线圈2发出笔压电磁信号，并断开悬浮线圈，关闭悬浮信号，电磁天线接收到笔压电磁信号，由电磁控制单元进行数据处理后，将处理结果发送至交互智能设备的系统进行数据处理，从而实现了在白板软件上的书写。待交互智能设备生成笔迹后，将笔迹显示在电磁屏的显示界面上。
实施例2

交互智能设备在接收到书写参数选择信号后，根据书写参数选择信号的信号频率确定书写参数。
在一种可选的实施例中，以书写参数选择信号为悬浮电磁信号为例，电磁笔上可以设置有选择开关，不同选择开关对应不同频率的悬浮电磁信号，其中，每种频率的悬浮电磁信号对应一组书写参数，用户将选择开关调整至对应的位置，当电磁笔接近电磁屏，进入电磁屏的有效控制区域时，电磁屏接收到用户所选的频率的悬浮电磁信号，交互智能设备基于频率和书写参数的关系，即可确定书写参数。
步骤S45，电磁笔向交互智能设备的电磁屏发出书写信号，其中，交互智能设备根据书写信号生成与书写参数对应的笔迹。
具体的，上述书写信号由发送书写参数选择信号的电磁笔接触电磁屏时发出，作为一种可选的实施例，上述书写信号为电磁笔发出的笔压电磁信号。
在上述方案中，用户使用电磁笔接触电磁屏后进行书写，书写出的笔迹与步骤S104中确定的书写参数相匹配。
在一种可选的实施例中，用户通过设置在电磁笔表面的选择开关，确定了输出的悬浮电磁信号的频率，用户拿起电磁笔靠近电磁屏进行书写，在电磁笔靠近电磁屏的过程中，首先进入电磁屏的有效控制区域，电磁笔发出与用户所选的频率对应的悬浮电磁信号。电磁屏接收到该频率的悬浮电磁信号，根据悬浮电磁信号的频率确定一组书写参数，其中，一组书写参数中可以包括多种书写参数，例如：书写颜色、笔迹类型等。当用户使用电磁笔接触电磁屏开始书写时，交互智能设备已经根据书写参数选择信号确定了书写参数，交互智能设备根据用户书写的轨迹，结合已确定书写参数，生成的笔迹即可。
当用户需要更换书写参数时，用户使电磁笔脱离电磁屏表面，通过调整上述选择开关来调整书写参数选择信号的信号频率，从而更改书写参数，当用户再次使用电磁笔接触到电磁屏进行书写时，交互智能设备生成的笔迹为更改后的书写参数。
尤其在用户的书写需要频繁的在多种类型的书写参数中切换时，上述实施例提供的方法为用户的书写提供了极大的遍历。
由上可知，本申请上述实施例，电磁笔接收控制信息，其中，控制信息用于确定书写参数选择信号的信号频率，电磁笔根据控制信息确定信号频率，并发出与信号频率对应的书写参数选择信号，其中，交互智能设备根据书写参数选择信号确定书写参数，电磁笔向交互智能设备的电磁屏发出书写信号，其中，交互智能设备根据书写信 号生成与书写参数对应的笔迹。上述方案中，由电磁笔发出书写参数选择信号，从而使得需要更换书写的颜色或笔迹类型时，无需手动操作交互智能设备上的控件，仅需向电磁笔发出控制信息即可，进而提高了用户使用电磁笔书写时的便捷性，解决了现有技术中更换电磁笔书写的颜色或书写类型时需要手动对书写软件进行控制，导致操作繁琐的技术问题。
作为一种可选的实施例，书写参数选择信号为悬浮电磁信号，当电磁笔处于交互智能设备的电磁屏的预设有效控制范围内，且未与电磁屏接触时，电磁笔向电磁屏发出书写参数选择信号，当电磁笔与电磁屏接触时，电磁笔发出书写信号。
电磁屏的预设有效控制范围是根据电磁屏的类型，以及书写参数选择信号的类型确定的，如果该书写参数选择信号为电磁信号，则有效控制范围可以是距离电磁屏5-30mm之内的范围，电磁笔与电磁屏之间的距离可以为电磁笔的笔尖到电磁屏之间的距离。
而如果电磁笔接触到电磁屏后，则会生成书写笔迹，因此书写参数选择信号是在电磁笔处于电磁屏的预设有效控制范围内，但未接触电磁屏时发出的。
在上述方案中，当电磁笔接进入电磁屏的有效控制范围，但并未与电磁屏接触时，电磁屏仅能检测到电磁笔发出的书写参数选择信号，当电磁笔的笔尖接触到电磁屏时，电磁屏既能检测到书写参数选择信号，也能检测到书写信号，在这种情况下，交互智能设备以书写信号优先，生成书写信号对应的笔迹。
