请参考图1，其是现有技术方案中智能笔系统的框架图，智能笔4的内部集成有MCU(Microccontroller Unit，微控制单元)41和第一wifi(Wireless-Fidelity，无线保真)模块42，MCU41和第一wifi模块42通过USB(Universal Serial Bus，通用串行总线)方式连接，实现MCU41对第一wifi模块42的状态控制。智能笔4与显示设备5之间采用wifi通信，主要是2.4G频段。智能笔4的第一wifi模块42通过RF(Radio Frequency，射频)协议，与显示设备5的第二wifi模块51搭建成局域网，控制芯片52根据智能笔4发出的控制命令执行相应的操作，实现智能笔的上下翻页等功能。

优选的，如图4所示，第二红外发射器31与第二红外接收器33分别设置两列，第二红外发射器31与第二红外接收器33在红外触摸框3的内侧壁相对设置。其中，第二红外发射器31与第二红外接收器33在红外触摸框3的内侧壁相对设置，这样使得第二红外发射器31可以尽量向更大的范围发射红外信号，也使得第二红外接收器33可以尽量接收到更大范围内的红外信号。
进一步的，红外触摸框3与上述显示面的朝向相同的一侧还设置有第三红外接收器34。其中，该第三红外接收器34用于接收上述智能笔1的第一红外发射器发射的红外信号，并将该红外信号转发给整机主控芯片。该第三红外接收器34设置于红外触摸框3边角的外表面，并垂直上述显示面，第三红外接收器 34的光敏元件(图未示)的朝向垂直上述显示面。当智能笔1离红外触摸框3的距离过远时，红外触摸框3的第二红外接收器33难以接收到智能笔1发出的红外信号，智能笔1的第一红外发射器发射的红外信号可以通过第三红外接收器34中转后发送给上述整机主控芯片，第三红外接收器34可以接收整机正前方15米及左右15°范围内的红外信号。
在本实施例中，第二红外接收器33可以为红外接收灯管，第二红外发射器31可以为红外发射灯管，第三红外接收器34可以为红外接收头。

一种控制方法，应用于上述任一实施例中所述的智能笔，包括：
S510：解码通过第一红外接收器接收的外部信号源发射的红外信号。
智能笔可以随时通过第一红外接收器接收外部存在的红外信号，示例性的，当智能笔进入到红外触摸框的智能笔识别区域时，可以通过智能笔内的第一红外接收器接收到红外触摸框发出的红外信号。其中，智能笔识别区域是指红外触摸框能识别智能笔的有效识别区域，该区域是在一定范围内的一个空间区域；红外触摸框相对于智能笔就是一个外部信号源，红外触摸框发出的红外信号中可以携带有完整的智能笔识别区域信息，还可以携带有完整的触摸框的特征码信息。
S520：判断解码红外信号得到的信息中是否携带有完整的智能笔识别区域信息。
示例性的，智能笔的第一红外接收器接收外部信号源发出的红外信号，将该红外信号传输给智能笔内的智能笔微处理器，智能笔微处理器对该红外信号进行解码处理，判断该红外信号是否携带有完整的智能笔识别区域信息及完整的触摸框的特征码信息。
S530：当确认携带有完整的智能笔识别区域信息时，激活智能笔以通过第一红外发射器发射携带有控制指令的红外信号。
示例性的，当智能笔微处理器对第一红外接收器接收的红外信号进行解码处理后，获得完整的智能笔识别区域信息及完整的触摸框的特征码信息，则确认该红外信号携带有完整的智能笔识别区域信息，智能笔微处理器激活智能笔使其处于工作激活状态，以使得智能笔能根据外部的控制操作控制智能笔微处理器生成相应的控制指令，并通过第一红外发射器向外发射携带有该控制指令的红外信号。
本方案中的智能笔不是随意激活并发射红外信号，而是需要对红外信号接收方的身份进行认证，基于身份认证的激活确认能够消除信号接收时的干扰， 只有认证后的智能笔才能被响应。
优选的，本实施例的控制方法还可以包括：
S540：获取控制指令，将控制指令编码并传输给第一红外发射器，以通过第一红外发射器发射携带有控制指令的红外信号。
示例性的，当智能笔处于工作激活状态，用户需要使用智能笔并按下智能笔上设置的控制按键时，智能笔微处理器生成相应的控制指令，并将该控制指令及智能笔的特征码进行编码，编码后的信息通过智能笔的第一红外发射器以红外信号的方式向外发射。
综上，在本技术方案中，通过智能笔的第一红外接收器接收外部信号源的红外信号，通过智能笔微处理器对该红外信号进行解码处理，若获得完整智能笔识别区域信息，则确定智能笔处于红外触摸框的智能笔识别区域范围内，激活智能笔使其处于工作激活状态，以使智能笔可以根据外部的控制命令，并通过智能笔微处理器及第一红外发射器向外发射携带有相应控制指令的红外信号；通过智能笔上的红外接收器及红外发射器，实现智能笔与红外触摸框间采用红外通信方式进行信号交互，可降低产品的生产成本，并减少外界信号的干扰。
实施例四

如果智能笔与显示设备是成套设备，那么智能笔与显示设备应预先相互保存对方的特征码信息，例如产品序列号、机器码等。
如果没有预先保存，智能笔识别区域信息编码除了包括红外触摸框的编码，还可进一步包括智能笔的特征码，智能笔的特征码可以由用户添加，使智能笔在第一次接收到智能笔识别区域信息时确认是发送给自身的信号，相当于进行一个简单的握手，初始化智能笔。
S620：智能笔微处理器解码通过第一红外接收器接收的外部信号源发射的红外信号。
示例性的，智能笔的第一红外接收器接收到外部信号源发射的红外信号，并将该红外信号传输给智能笔微处理器，智能笔微处理器对该红外信号进行解码处理。其中，外部信号源可以为红外触摸框，或为其他可发出红外信号的设备。对于智能笔而言，在接收到红外信号时是无法确认该红外信号的来源，只有对红外信号进行解码后才能明确该红外信号的来源，根据解码结果进行后续操作。
S630：智能笔微处理器判断通过解码外部信号源发射的红外信号得到的信息中是否携带有完整的智能笔识别区域信息。
示例性的，智能笔微处理器对接收到的外部信号源发射的红外信号进行解码后，根据解码后的信息中各信息成分来判断外部信号源发射的红外信号是否携带有完整的智能笔识别区域信息及红外触摸框的特征码信息。与步骤S610对 应的，如果是初次接收到红外信号，该红外信号携带的完整的信息应该包括智能笔自身的特征码。
S640：当确认携带有完整的智能笔识别区域信息时，智能笔微处理器激活智能笔以通过第一红外发射器发射携带有控制指令的红外信号。
示例性的，当智能笔微处理器分析出外部信号源发射的红外信号携带有完整的智能笔识别区域信息及红外触摸框的特征码信息时，确认智能笔处于红外触摸框的智能笔识别区域，则激活智能笔使其处于工作激活状态，使得智能笔微处理器可以根据外部的控制操作生成相应的控制指令，智能笔微处理器将智能笔的特征码和该控制指令进行编码，将编码后的包括智能笔的特征码和该控制指令的码值信息，以红外信号的方式向外发射。其中，智能笔识别区域是指红外触摸框能识别智能笔的有效识别区域，该区域是在一定范围内的一个空间区域，在本实施例中该区域的范围大小可调，例如可设置垂直距红外触摸框20厘米范围内为智能笔识别区域，当智能笔进入到该智能笔识别区域时，激活智能笔，整机系统自动打开电子白板应用，或其它自定义功能，例如PPT(Power Point，演示文稿)批注等。
该红外信号中，不仅仅携带有控制指令的码值信息，还携带有发送该红外信号的主体信息，也就是智能笔的特征码，在后续步骤中，通过特征码消除其他红外信号源的红外信号的干扰。
优选的，本实施例的交互方法还可以包括：
S650：获取控制指令，将控制指令编码并传输给第一红外发射器，以通过第一红外发射器发射携带有控制指令的红外信号。

S660：触摸框微处理器解码第二红外接收器接收的红外信号，以获取控制指令。
示例性的，红外触摸框上的第二红外接收器接收到智能笔端发射的红外信号，并将该红外信号传输给触摸框微处理器，触摸框微处理器对该红外信号进行解码处理，以获取智能笔的特征码和控制指令的码值信息，并根据码值信息获得相应的控制指令。
进一步的，本实施例的交互方法还可以包括：
S670：确认获取到的特征码与当前交互智能笔的特征码匹配，响应码值信息对应的控制指令。
示例性的，触摸框微处理器解码接收到的红外信号获得控制指令和特征码，并确认该特征码即为与当前交互智能笔的特征码，则将该控制指令传输给整机主控芯片，以使整机主控芯片响应该控制指令执行相应的操作。
综上，在本技术方案中，通过分别设置于智能笔和红外触摸框上的红外接收器及红外发射器，实现智能笔与红外触摸框之间的红外通信，可降低产品的生产成本，并减少外界信号的干扰；此外，通过红外通信方式，智能笔进入到红外触摸框的智能笔识别区域时即可激活智能笔，实现红外触摸框对智能笔的悬浮识别，极大地提升了用户体验。
