具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种终端设备防信号干扰的方法。参照图1，图1为本发明的终端设备防信号干扰的方法一实施例的流程图。在一实施例中，所述终端设备防信号干扰的方法包括：
步骤S10、监测终端设备是否存在占用2.4G频段中频点通道终端设备自身的2.4G无线通信信号。
参见图2，图2为图1中步骤S10的具体细化流程图。所述步骤S10具体处理过程如下：
步骤S11、读取终端设备内与终端设备的主控制器建立I/O连接的模块ID信息，将所获取的ID信息与预设的2.4G无线通信模块ID信息进行匹配；匹配成功则对应的模块为2.4G无线通信模块。
步骤S12、读取匹配成功的所述2.4G无线通信模块的状态信息，根据所述状态信息确定所述2.4G无线通信模块是否产生占用2.4G频段中频点通道的2.4G无线通信信号。
本步骤S12中当存在产生占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号的2.4G无线通信模块，则表示终端设备存在占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号。所述2.4G无线通信模块的状态信息包括该2.4G无线通信模块的工作模式，其中所述工作模式包括以下几种情况：（1）、2.4G无线通信模块处于关闭状态；（2）、2.4G无线通信模块处于开启状态，但未进行数据通信；（3）、2.4G无线通信模块处于开启状态，并进行数据通信。当所述2.4G无线通信模块中某一2.4G无线通信模块的工作模式为上述工作模式（3），则该某一2.4G无线通信模块的状态信息还包括：该某一2.4G无线通信模块进行数据通信所产生的信号强度，以及所占用的频点通道。即该某一2.4G无线通信模块产生了占用2.4G频段中频点通道的2.4G无线通信信号。其中，当所述2.4G无线通信模块中存在工作模式为上述工作模式（3）的2.4G无线通信模块，则表示终端设备存在占用2.4G频段中频点通道的2.4G无线通信信号。
步骤S20、当终端设备存在占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号，根据所述终端设备自身的2.4G无线通信信号强度确定所述2.4G频段中第一可用频点通道。
进一步地，当终端设备不存在占用2.4G频段中频点通道的2.4G无线通信信号，则确定2.4G频段所有频点通道为第一可用频点通道。
参见图3，图3为图1中步骤S20的具体细化流程图。所述步骤S20具体处理过程如下：
步骤S21、获取所述占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号的信号强度，判断该信号强度是否处于预设的信号强度阈值范围内。
由于当终端设备自身的其他2.4G无线通信信号强度大于2.4G私有协议通信信号强度，并达到一预设的信号强度阈值，则该其他2.4G无线通信信号会干扰到占用同一频点通道的2.4G私有协议通信信号。而当终端设备自身的其他2.4G无线通信信号强度小于2.4G私有协议通信信号强度，并达到一预设的信号强度阈值，则2.4G私有协议通信信号会干扰到占用同一频点通道的该其他2.4G无线通信信号。本实施例为了防止2.4G私有协议通信信号与占用同一频点通道的其他2.4G无线通信信号相互干扰，预先设置终端设备自身的其他2.4G无线通信信号的信号强度阈值范围，以确保信号强度在该信号强度范围内的其他2.4G无线通信信号不会对占用同一频点通道的2.4G私有协议通信信号产生干扰，同时也不会被占用同一频点通道的2.4G私有协议通信信号产生干扰。
步骤S22、确定信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号所占用的频点通道为不可用频点通道。
由上可知，信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号，可能会对占用同一频点通道的2.4G私有协议通信信号产生干扰，或者被对占用同一频点通道的2.4G私有协议通信信号干扰。因此为了确保2.4G私有协议通信信号与占用同一频点通道的其他2.4无线通信信号相互之间不产生干扰，不能将信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号所占用的频点通道作为可用频点通道实现2.4G私有协议通信信号传输。
步骤S23、确定所述2.4G频段中除所述确定为不可用频点通道以外的频点通道为第一可用频点通道。
本步骤S23中所述第一可用频点通道包括：所述2.4G频段中未被终端设备其他2.4G无线通信信号占用的频点通道，以及信号强度处于所述信号强度阈值范围内的终端设备中其他2.4G无线通信信号占用的频点通道。
以下以一个具体实例对所述步骤S20进行具体描述：
假设预先设置的信号强度阈值范围为：-60dBm至-35dBm；若某一2.4G无线通信信号强度为-30dBm，即大于-35dBm的强信号，则确定该2.4G无线通信信号占用的频点通道为第一不可用频点通道；若某一2.4G无线通信信号强度为-65dBm ，即小于-60dBm的弱信号，则确定该2.4G无线通信信号占用的频点通道为第一不可用频点通道；若某一2.4G无线通信信号强度为-50dBm，即处于所述信号强度阈值范围（-60dBm至-35dBm)内，则确定该2.4G无线通信信号占用的频点通道为第一可用频点通道。本实施例中发送2.4G无线通信信号的2.4G通信模块可以是：WIFI模块、蓝牙模块、ZIGBEE模块等无线通信模块，而发送2.4G私有协议通信信号的通信模块可以是：如发送2.4G射频信号的通信模块。
步骤S30、监测所述终端设备外部是否存在占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号。
本步骤中通过天线对所述终端设备以外的占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号进行监测。
步骤S40、当所述终端设备外部存在占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号，根据所述外部2.4G无线通信信号强度，或根据2.4G私有协议通信数据通过所述外部2.4G无线通信信号所占用的频点通道进行通信质量测试的结果，在第一可用频点通道中确定第二可用频点通道。
进一步地，当所述终端设备外部不存在占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号，则直接确定第一可用频点通道中所有频点通道为第二可用频点通道。
参见图4，图4为图1中步骤S40的具体细化流程图。所述步骤S40中所述根据2.4G私有协议通信数据通过所述外部2.4G无线通信信号所占用的频点通道进行通信质量测试的结果，在第一可用频点通道中确定第二可用频点通道具体包括：
步骤S41、通过所述外部2.4G无线通信信号所占用的每一频点通道进行2.4G私有协议通信数据的传输。其中2.4G私有协议通信数据可是2.4G私有协议的测试数据，而2.4G私有协议通信信号即待发送的2.4G私有协议的通信数据。
步骤S42、计算每一频点通道传输数据的数据掉包率，并将每一频点通道对应的数据掉包率与预设的数据掉包率阈值进行比较。
步骤S43、将数据掉包率大于所述数据掉包率阈值对应的频点通道确定为第二不可用频点通道。
步骤S44、确定所述第一可用频点通道中除所述确定为第二不可用频点通道以外的频点通道为第二可用频点通道。
本步骤S44中所述第二可用频点通道包括第一可用频点通道中未被所述外部2.4G无线通信信号所占用的频点通道，以及第一可用频点通道中被所述外部2.4G无线通信信号所占用但进行2.4G私有协议通信数据的传输时数据丢包率小于或等于预设的数据掉包率阈值所对应的频点通道。
参见图5，图5为图1中步骤S40的另一具体细化流程图。所述步骤S40根据所述外部2.4G无线通信信号强度，在第一可用频点通道中确定第二可用频点通道还可以采用如下具体处理步骤实现：
步骤S401、计算每一外部2.4G无线通信信号的信号强度，并将每一外部2.4G无线通信信号的信号强度与预设的信号强度阈值进行比较。
步骤S402、将信号强度大于所述信号强度阈值对应的外部2.4G无线通信信号所占用的频点通道确定为第二不可用频点通道。
步骤S403、确定所述第一可用频点通道中除所述确定为第二不可用频点通道以外的频点通道为第二可用频点通道。
本步骤S403中所述第二可用频点通道包括：第一可用频点通道中未被所述外部2.4G无线通信信号所占用的频点通道，以及第一可用频点通道中被所述外部2.4G无线通信信号所占用，但信号强度小于或等于信号强度阈值所对应的频点通道。
步骤S50、从第二可用频点通道中选择部分频点通道进行2.4G私有协议数据传输。
本实施例中可以从第二可用频点通道中选择部分频点通道作为进行2.4私有协议通信信号传输的频点通道。其中2.4私有协议通信模块进行通信信号传输具体为：根据所选的频点通道中每个频点通道的频率大小，按低频到高频的顺序，或者按高频到低频的顺序依次选择一个频点通道进行数据传输。

本发明进一步提供一种终端设备100。参照图6，图6为本发明的终端设备一功能模块示意图。在该实施例中，所述终端设备100包括：第一监测模块110、第一确定模块120、第二监测模块130、第二确定模块140，频点通道选择模块150。其中，所述第一监测模块110，用于监测终端设备100是否存在占用2.4G频段中频点通道的2.4G无线通信信号。所述第一确定模块120，用于当终端设备100中存在占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号，根据所述终端设备自身的2.4G无线通信信号强度确定所述2.4G频段中第一可用频点通道。所述第二监测模块130，用于监测所述终端设备100外部是否存在占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号。所述第二确定模块140，用于当所述终端设备100以外存在占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号，根据所述外部2.4G无线通信信号强度，或根据2.4G私有协议通信数据通过所述外部2.4G无线通信信号所占用的频点通道进行通信质量测试的结果，在第一可用频点通道中确定第二可用频点通道。所述频点通道选择模块150，用于从第二可用频点通道中选择部分频点通道进行2.4G私有协议通信信号的传输。
本实施例中通过天线对所述终端设备100以外的占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号进行监测。所述频点通道选择模块150可以从第二可用频点通道中选择部分频点通道作为进行2.4私有协议通信信号传输的频点通道。其中2.4私有协议数据传输具体为：根据所选的频点通道中每个频点通道的频率大小，按低频到高频的顺序，或者按高频到低频的顺序依次选择一个频点通道进行数据传输。
上述实施例中，所述第一监测模块110，具体用于读取终端设备内与终端设备100的主控制器建立I/O连接的模块ID信息，将所获取的ID信息与预设的2.4G无线通信模块ID信息进行匹配；匹配成功则对应的模块为2.4G无线通信模块；读取匹配成功的所述2.4G无线通信模块的状态信息，根据所述状态信息确定所述2.4G无线通信模块是否产生占用2.4G频段中频点通道的2.4G无线通信信号；当存在产生占用2.4G频段中频点通道的2.4G无线通信信号的2.4G无线通信模块，则表示终端设备100存在占用2.4G频段中频点通道的2.4G无线通信信号。
本实施例中所述2.4G无线通信模块的状态信息包括该2.4G无线通信模块产生工作模式，其中所述工作模式包括以下几种情况：（1）、2.4G无线通信功能处于关闭状态；（2）、2.4G无线通信功能处于开启状态，但未进行数据通信；（3）、2.4G无线通信功能处于开启状态，并进行数据通信。当所述2.4G无线通信模块中某一2.4G无线通信模块的工作模式为上述工作模式（3），则该某一2.4G无线通信模块的状态信息还包括：该某一2.4G无线通信模块进行数据通信所产生的信号强度，以及所占用的频点通道。即该某一2.4G无线通信模块产生了占用2.4G频段中频点通道的2.4G无线通信信号。即当所述2.4G无线通信模块中存在工作模式为上述工作模式（3）的2.4G无线通信模块，则表示终端设备100存在占用2.4G频段中频点通道的2.4G无线通信信号。
本实施例中，当终端设备不存在占用2.4G频段中频点通道的2.4G无线通信信号，则确定2.4G频段所有频点通道为第一可用频点通道。
上述实施例中，所述第一确定模块120，具体用于获取所述占用2.4G频段中频点通道的2.4G无线通信信号的信号强度，判断该信号强度是否处于预设的信号强度阈值范围内；确定信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号所占用的频点通道为不可用频点通道；确定所述2.4G频段中除所述确定为不可用频点通道以外的频点通道为第一可用频点通道。
本实施例中，由于当终端设备100自身的其他2.4G无线通信信号强度大于2.4G私有协议通信信号强度，并达到一预设的信号强度阈值，则该其他2.4G无线通信信号会干扰到占用同一频点通道的2.4G私有协议通信信号。而当终端设备100自身的其他2.4G无线通信信号强度小于2.4G私有协议通信信号强度，并达到一预设的信号强度阈，则2.4G私有协议通信信号会干扰到占用同一频点通道的该其他2.4G无线通信信号。本实施例为了防止2.4G私有协议通信信号与占用同一频点通道的其他2.4G无线通信信号相互干扰，预先设置终端设备100自身的其他2.4G无线通信信号的信号强度阈值范围，以确保信号强度在该信号强度范围内的其他2.4G无线通信信号不会对占用同一频点通道的2.4G私有协议通信信号产生干扰，同时也不会被占用同一频点通道的2.4G私有协议通信信号产生干扰。
由上可知，信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号，可能会对占用同一频点通道的2.4G私有协议通信信号产生干扰，或者被对占用同一频点通道的2.4G私有协议通信信号干扰。因此本实施例为了确保2.4G私有协议通信信号与占用同一频点通道的其他2.4无线通信信号相互之间不产生干扰，不能将信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号所占用的频点通道作为可用频点通道实现2.4G私有协议通信信号传输。本实施例中所述第一可用频点通道包括：所述2.4G频段中未被终端设备100其他2.4G无线通信信号占用的频点通道，以及信号强度处于所述信号强度阈值范围内的终端设备100中其他2.4G无线通信信号占用的频点通道。
以下以一个具体实例对所述第一确定模块120的功能进行具体描述：假设预先设置的信号强度阈值范围为：-60dBm至-35dBm；若某一2.4G无线通信信号强度为-30dBm，即大于-35dBm的强信号，则确定该2.4G无线通信信号占用的频点通道为第一不可用频点通道；若某一2.4G无线通信信号强度为-65dBm ，即小于-60dBm的弱信号，则确定该2.4G无线通信信号占用的频点通道为第一不可用频点通道；若某一2.4G无线通信信号强度为-50dBm，即处于所述信号强度阈值范围（-60dBm至-35dBm)内，则确定该2.4G无线通信信号占用的频点通道为第一可用频点通道。本实施例中发送2.4G无线通信信号的2.4G通信模块可以是：WIFI模块、蓝牙模块、ZIGBEE模块等无线通信模块，而发送2.4G私有协议通信信号的通信模块可以是：如发送2.4G射频信号的通信模块。
上述实施例中，所述第二确定模块140，具体用于通过所述外部2.4G无线通信信号所占用的每一频点通道进行2.4G私有协议通信数据的传输；计算每一频点通道传输数据的数据掉包率，并将每一频点通道对应的数据掉包率与预设的数据掉包率阈值进行比较；将数据掉包率大于所述数据掉包率阈值对应的频点通道确定为第二不可用频点通道；确定所述第一可用频点通道中除所述确定为第二不可用频点通道以外的频点通道为第二可用频点通道。本实施例中所述第二可用频点通道包括第一可用频点通道中未被所述外部2.4G无线通信信号所占用的频点通道，以及第一可用频点通道中被所述外部2.4G无线通信信号所占用但进行2.4G私有协议传输数据时数据丢包率小于或等于预设的数据掉包率阈值所对应的频点通道。其中2.4G私有协议通信数据可是2.4G私有协议的测试数据，而2.4G私有协议通信信号即待发送的2.4G私有协议的通信数据。
上述实施例中，所述第二确定模块140还可以采用以下方式实现在第一可用频点通道中确定第二可用频点通道：计算每一外部2.4G无线通信信号的信号强度，并将每一外部2.4G无线通信信号的信号强度与预设的信号强度阈值进行比较；将信号强度大于所述信号强度阈值对应的外部2.4G无线通信信号所占用的频点通道确定为第二不可用频点通道；确定所述第一可用频点通道中除所述确定为第二不可用频点通道以外的频点通道为第二可用频点通道。本实施例中所述第二可用频点通道包括：第一可用频点通道中未被所述外部2.4G无线通信信号所占用的频点通道，以及第一可用频点通道中被所述外部2.4G无线通信信号所占用，但信号强度小于或等于信号强度阈值所对应的频点通道。
另外，当所述终端设备外部不存在占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号，所述第二确定模块140则可以直接确定第一可用频点通道中所有频点通道为第二可用频点通道。
上述终端设备100实施例，通过监测终端设备是否存在占用2.4G频段中频点通道的2.4G无线通信信号；当存在，根据所述2.4G无线通信信号强度确定所述2.4G频段中第一可用频点通道；监测所述终端设备以外是否存在占用所述第一可用频点通道中频点通道的外部2.4G无线通信信号；当存在，则根据所述外部2.4G无线通信信号强度，或根据2.4G私有协议通信信号通过所述外部2.4G无线通信信号所占用的频点通道进行通信质量测试的结果，在第一可用频点通道中确定第二可用频点通道；从第二可用频点通道中选择部分频点通道进行2.4G私有协议数据传输的方式，能够有效地防止终端设备的2.4G私有协议通信信号与终端设备自身以及外部环境中的其他2.4G无线通信信号之间形成干扰，从而保证了终端设备的2.4G私有协议通信信号以及其他2.4G无线通信信号的传输质量。
本发明提供一种终端设备防信号干扰的方法。参照图7，图7为本发明的终端设备防信号干扰的方法另一实施例的流程图。在本实施例中，所述终端设备防信号干扰的方法包括：
步骤S101、监测终端设备是否存在占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号。
参见图8，图8为图7中步骤S101的具体细化流程图。所述步骤S101具体处理过程如下：
步骤S1011、读取终端设备内与终端设备的主控制器建立I/O连接的模块ID信息，将所获取的ID信息与预设的2.4G无线通信模块ID信息进行匹配；匹配成功则对应的模块为2.4G无线通信模块。
步骤S1012、读取匹配成功的所述2.4G无线通信模块的状态信息，根据所述状态信息确定所述2.4G无线通信模块是否产生占用2.4G频段中频点通道的2.4G无线通信信号。
本实施例中，当存在产生占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号的2.4G无线通信模块，则表示终端设备存在占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号。

步骤S1021、获取所述占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号的信号强度，判断该信号强度是否处于预设的信号强度阈值范围内。
由于当终端设备自身的其他2.4G无线通信信号强度大于2.4G私有协议通信信号强度，并达到一预设信号强度阈值，则该其他2.4G无线通信信号会干扰到占用同一频点通道的2.4G私有协议通信信号。而当终端设备自身的其他2.4G无线通信信号强度小于2.4G私有协议通信信号强度，并达到一预设信号强度阈值，则2.4G私有协议通信信号会干扰到占用同一频点通道的该其他2.4G无线通信信号。本实施例为了防止2.4G私有协议通信信号与占用同一频点通道的其他2.4G无线通信信号相互干扰，预先设置终端设备自身的其他2.4G无线通信信号的信号强度阈值范围，以确保信号强度在该信号强度范围内的其他2.4G无线通信信号不会对占用同一频点通道的2.4G私有协议通信信号产生干扰，同时也不会被占用同一频点通道的2.4G私有协议通信信号产生干扰。

本实施例中，当终端设备不存在占用2.4G频段中频点通道的其他2.4G无线通信信号，则确定2.4G频段所有频点通道为可用频点通道。
本实施例中，可以从可用频点通道中随机选择部分频点通道作为进行2.4私有协议通信信号传输的频点通道。其中2.4私有协议通信模块进行数据传输具体为：根据所选的频点通道中每个频点通道的频率大小，按低频到高频的顺序，或者按高频到低频的顺序依次选择一个频点通道进行数据传输。
上述终端设备防信号干扰的方法实施例，通过监测终端设备是否存在占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号；当存在，根据所述终端设备自身的2.4G无线通信信号强度确定所述2.4G频段中可用频点通道；从所述可用频点通道中选择部分频点通道进行2.4G私有协议数据传输的方式，能够有效地防止终端设备的2.4G私有协议通信信号与终端设备自身的其他2.4G无线通信信号之间形成干扰，从而保证了终端设备的2.4G私有协议通信信号以及终端设备自身的其他2.4G无线通信信号的传输质量。
本发明进一步提供一种终端设备200。参照图10，图10为本发明的另一终端设备一功能模块示意图。在该实施例中，所述终端设备200包括：监测模块210、确定模块220、选择模块230。其中，所述监测模块210，用于监测终端设备200是否存在占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号。所述确定模块220，用于终端设备200存在占用2.4G频段中频点通道的2.4G无线通信信号，根据所述终端设备自身的2.4G无线通信信号强度确定所述2.4G频段中可用频点通道。所述选择模块230，用于从所述可用频点通道中选择部分频点通道进行2.4G私有协议通信信号的传输。
本实施例中所述选择模块230可以从可用频点通道中随机选择部分频点通道作为进行2.4私有协议数据传输的频点通道。其中2.4私有协议数据传输具体为：根据所选的频点通道中每个频点通道的频率大小，按低频到高频的顺序，或者按高频到低频的顺序依次选择一个频点通道进行通信信号的传输。
上述实施例中所述监测模块210，具体用于读取终端设备内与终端设备200的主控制器建立I/O连接的模块ID信息，将所获取的ID信息与预设的2.4G无线通信模块ID信息进行匹配；匹配成功则对应的模块为2.4G无线通信模块；读取匹配成功的所述2.4G无线通信模块的状态信息，根据所述状态信息确定所述2.4G无线通信模块是否产生占用2.4G频段中频点通道的2.4G无线通信信号；当存在产生占用2.4G频段中频点通道的2.4G无线通信信号的2.4G无线通信模块，则表示终端设备200存在占用2.4G频段中频点通道的2.4G无线通信信号。
本实施例中所述2.4G无线通信模块的状态信息包括该2.4G无线通信模块产生工作模式，其中所述工作模式包括以下几种情况：（1）、2.4G无线通信功能处于关闭状态；（2）、2.4G无线通信功能处于开启状态，但未进行数据通信；（3）、2.4G无线通信功能处于开启状态，并进行数据通信。当所述2.4G无线通信模块中某一2.4G无线通信模块的工作模式为上述工作模式（3），则该某一2.4G无线通信模块的状态信息还包括：该某一2.4G无线通信模块进行数据通信所产生的信号强度，以及所占用的频点通道。即该某一2.4G无线通信模块产生了占用2.4G频段中频点通道的2.4G无线通信信号。即当所述2.4G无线通信模块中存在工作模式为上述工作模式（3）的2.4G无线通信模块，则表示终端设备200存在占用2.4G频段中频点通道的2.4G无线通信信号。
上述实施例中所述确定模块220，具体还用于获取所述占用2.4G频段中频点通道的2.4G无线通信信号的信号强度，判断该信号强度是否处于预设的信号强度阈值范围内；确定信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号所占用的频点通道为不可用频点通道；确定所述2.4G频段中除所述确定为不可用频点通道以外的频点通道为可用频点通道。
本实施例中，当终端设备不存在占用2.4G频段中频点通道的其他2.4G无线通信信号，则确定2.4G频段所有频点通道为可用频点通道。
由于当终端设备200自身的其他2.4G无线通信信号强度大于2.4G私有协议通信信号强度，并达到一预设的信号强度阈值，则该其他2.4G无线通信信号会干扰到占用同一频点通道的2.4G私有协议通信信号。而当终端设备200自身的其他2.4G无线通信信号强度小于2.4G私有协议通信信号强度，并达到一预设的信号强度阈，则2.4G私有协议通信信号会干扰到占用同一频点通道的该其他2.4G无线通信信号。本实施例为了防止2.4G私有协议通信信号与占用同一频点通道的其他2.4G无线通信信号相互干扰，预先设置终端设备200自身的其他2.4G无线通信信号的信号强度阈值范围，以确保信号强度在该信号强度范围内的其他2.4G无线通信信号不会对占用同一频点通道的2.4G私有协议通信信号产生干扰，同时也不会被占用同一频点通道的2.4G私有协议通信信号产生干扰。
由上可知，信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号，可能会对占用同一频点通道的2.4G私有协议通信信号产生干扰，或者被对占用同一频点通道的2.4G私有协议通信信号干扰。因此为了确保2.4G私有协议通信信号与占用同一频点通道的其他2.4无线通信信号相互之间不产生干扰，不能将信号强度未处于所述信号强度阈值范围内的2.4G无线通信信号所占用的频点通道作为可用频点通道实现2.4G私有协议通信信号传输。本实施例中中所述可用频点通道包括：所述2.4G频段中未被终端设备200其他2.4G无线通信信号占用的频点通道，以及信号强度处于所述信号强度阈值范围内的终端设备200中其他2.4G无线通信信号占用的频点通道。
以下以一个具体实例对所述确定模块220的功能进行具体描述：假设预先设置的信号强度阈值范围为：-60dBm至-35dBm；若某一2.4G无线通信信号强度为-30dBm，即大于-35dBm的强信号，则确定该2.4G无线通信信号占用的频点通道为不可用频点通道；若某一2.4G无线通信信号强度为-65dBm ，即小于-60dBm的弱信号，则确定该2.4G无线通信信号占用的频点通道为不可用频点通道；若某一2.4G无线通信信号强度为-50dBm，即处于所述信号强度阈值范围（-60dBm至-35dBm)内，则确定该2.4G无线通信信号占用的频点通道为可用频点通道。本实施例中发送2.4G无线通信信号的2.4G通信模块可以是：WIFI模块、蓝牙模块、ZIGBEE模块等无线通信模块，而发送2.4G私有协议通信信号的通信模块可以是：如发送2.4G射频信号的通信模块。
上述终端设备200实施例，通过监测终端设备是否存在占用2.4G频段中频点通道的终端设备自身的2.4G无线通信信号；当存在，根据所述终端设备自身的2.4G无线通信信号强度确定所述2.4G频段中可用频点通道；从所述可用频点通道中选择部分频点通道进行2.4G私有协议数据传输的方式，能够有效地防止终端设备的2.4G私有协议通信信号与终端设备自身的其他2.4G无线通信信号之间形成干扰，从而保证了终端设备的2.4G私有协议通信信号以及终端设备自身的其他2.4G无线通信信号的传输质量。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
