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。
本发明提供一种智能电视终端锁定方法。
参照图1，图1为本发明智能电视终端锁定方法第一实施例的流程示意图。
本实施例提出一种智能电视终端锁定方法，所述智能电视终端锁定方法包括：
步骤S10，开机时，扫描终端所处的环境中的无线网络以获取当前无线网络信息；
在本实施例中，搜索智能电视终端所处的环境中的无线网络信号的步骤可在多种状态下执行，1)可在开机后，检测智能电视终端的无线网络开关是否开启，在无线网络开关未开启时，开启所述智能电视终端的无线网络开关；搜索智能电视终端所处的环境中的无线网络信号，以获取当前无线网络信息；2)在智能电视终端运行过程中定时搜索终端所处环境中的无线网络信号，以获取当前无线网络信息。
步骤S20，根据所述当前无线网络信息和所述终端中存储的基准无线网络信息判断终端所处的环境是否变化；
在本实施例中，根据所述当前无线网络信息和所述终端中存储的基准无线网络信息判断终端所处的环境是否变化可通过以下方式实现：
1)第一实施例，参照图2，所述步骤S20包括：
步骤S21，根据当前无线网络信息和基准无线网络信息计算环境安全系数；
所述无线网络信息包括搜索到的无线网络信号的网络标识以及信号强度。
步骤S22，根据环境安全系数判断所处环境是否发生变化。
在本实施例中，所述步骤S21包括：
将预存的基准无线网络信息依次与获取到的无线网络信息进行比对，以确定基准无线网络信息与当前无线网络信息对应的网络标识以及信号权重；
将同一网络标识的信号权重进行与运算，并根据与运算结果计算各个网络标识对应的信任系数和变化值；
基于获取到的信任系数和变化值，确定搜索到的各个网络标识对应的无线网络信号的变化系数；
对各个变化系数进行求和，得到当前环境安全系数。
其中，在没有基准无线网络信息与扫描到的无线网络信号的网络标识相同时，基准无线网络信息中，该网络标识对应的无线网络信息信号强度为0，即信号权重为0；在有基准无线网络信息与扫描到的无线网络信号的网络标识相同时，基准无线网络信息中，该网络标识对应的无线网络信息信号强度大于0，即信号权重为1。
例如，在当前搜索到的无线网络信息对应的信号强度大于0，且网络标识为A，则当前的信号权重L为1，在预存的基准无线网络信息中没有网络标识为A的基准网络信息时，网络标识为A的基准无线网络信息对应的信号强度为0，此时该网络标识为A基准无线网络信息对应的权重L″为0，当L&&L″＝＝0时，则P(信任系数)＝0.9，M(变化值)＝1，k(变化系数)＝0.9×1＝0.9；在当前搜索到的无线网络信息对应的信号强度大于0，且网络标识为A，则当前的信号权重L为1，在预存的基准无线网络信息中没有网络标识为A的基准网络信息，则网络标识为A的基准无线网络信息对应的信号强度大于0，即基准无线网络信息对应的权重L″为1，当L&&L″＝1时，则P(信任系数)＝0.1，M(变化值)＝-1，k(变化系数)＝0.1×(-1)＝-0.1，则变化系数的计算公式为ki＝Pi×Mi，安全系数为各个变化系数的总和，即环境安全系数的计算公式为
Figure PCTCN2014095521-appb-000001
其中，K为安全系数，ki为各个网络信息对应的变化系数。
在当前环境安全系数小于等于零时，认为终端所处的环境变化，在当前环境安全系数大于零时，认为终端所处的环境未变化。
在本实施例中，上述权重值、信任系数以及变化值所对应的值为优选实施例，软件开发人员可根据需要上述值进行设定。
2)第二实施例，所述步骤S20包括：在获取到当前网络信息时，将当前网络信息与所述基准无线网络信息进行比对，以确定所述基准无线网络信息对应的无线网络信号是否被搜索到；在基准无线网络信息对应的网络信号被搜索到时，终端所处的环境未变化；在在基准无线网络信息对应的网络信号未被搜索到时，终端所处的环境发生变化。本实施例中，直接通过是否搜索到基准无线网络信息对应的无线网络信号来判断终端所处的运行环境是否改变，较为准确。
以上所列举出的两种判断终端所处的环境是否变化的方式仅仅为示例性的，本领域技术人员利用本发明的技术思想，根据其具体需求所提出的其他判断终端所处的环境是否变化的方式均在本发明的保护范围内，在此不进行一一穷举。
步骤S30，在搜索到的网络信号与预存的网络信号不匹配时，锁定所述终端。
在本实施例中，锁定所述终端时，可锁定终端的所有功能，使得终端无法进行任何操作；或者，仅锁定终端中预设类型的功能，使得用户无法针对某些功能项进行操作，如参数的修改等；或者，锁定终端中预设的资料，如图片以及视频的等。该锁定终端的方式可由用户进行设定，即在搜索到的网络信号与预存的网络信号不匹配时，按照当前设定的锁定方式锁定所述终端。
本领域技术人员可以理解的是，为提高对终端锁定的智能化，在锁定所述终端之后获取预存的安全联系方式；将锁定信息发送至所述安全联系方式对应的终端，以及时提醒用户终端所处的环境改变。进一步地，该锁定信息中可包含终端当前的位置信息。该安全联系方式可为电话号码及/或邮件地址等。
该预存的安全联系地址可在终端第一次开机时设置，如在开机后获取开机标志位，在开机标志位为0时，显示安全联系地址设置界面，以供用户基于所述安全联系地址设置界面输入安全联系地址；存储用户输入的所述安全联系地址。在本领域技术人员可以理解的是，在设置安全联系地址的同时可进行解锁信息的设置。
进一步地，步骤S10之后还包括步骤：在终端中未存储基准无线网络信息时，将扫描到的无线网络信息作为所述终端的基准无线网络信息。在未预存基准无线网络信息时，说明终端为第一次使用，或者终端中预存的基准无线网络信息被删除，此时将扫描得到的基准无线网络信息作为基准无线网络信息。
本实施例提出的智能电视终端锁定方法，当终端所处的环境发生变化时，可通过锁定所述终端的方式防止终端中的数据丢失，使得终端在所处的环境发生变化时能实现锁定操作，提高终端的安全性。
进一步地，为提高对终端锁定的灵活性，参照图3，基于第一实施例提出本发明智能电视终端锁定方法的第二实施例，在本实施例中，所述步骤S30之后还包括步骤：
步骤S40，显示解锁信息输入界面，以供用户基于所述解锁信息输入界面输入解锁信息；
在本实施例中，该解锁信息可为解锁密码，用户可基于信息输入界面直接输入密码信息，或者第三方装置(如手表以及手机等)通过近场通讯的方式将存储的密码发送至所述终端；该解锁信息也可为预设的音频信号或者预设的手势等，用户基于所述解锁信息输入界面输入相应的手势或者语音信号。
步骤S50，在用户输入的解锁信息与预存的解锁信息匹配时，解除对所述终端的锁定；
在本实施例中，解除对所述终端的锁定是指控制所述终端正常运行。该预存的解锁信息可在终端第一次开机时设置，如在开机后获取开机标志位，在开机标志位为0时，显示解锁信息设置界面，以供用户基于所述解锁信息设置界面输入解锁信息；存储用户输入的所述解锁信息。用户也可在终端的运行过程中，修改预存的密码信息，即该智能电视终端锁定方法还包括：在接收到解锁信息修改指令时，显示解锁信息修改界面，以供用户基于所述解锁信息修改界面输入解锁信息；采用用户输入的所述解锁信息更新预存的解锁信息。
步骤S60，采用当前搜索到的无线信号更新预存的基准无线网络信息。
在用户输入的解锁信息与预存的解锁信息匹配时，说明终端可能没有被 盗，仅仅是将终端的位置移到其他位置而已，故解除对所述终端的锁定之后，可采用当前搜索到的无线信号更新预存的无线信号。本领域技术人员可以理解的是，为保证无线信号更新的准确性，所述步骤S60包括：显示无线信号更新选择界面，以供用户基于所述更新选择界面输入确认或者拒绝更新所述无线信号的信息；在接收到用户输入的确认信息时，采用当前搜索到的无线信号更新预存的无线信号。在在接收到用户输入的确认信息时，可不做任何处理。
本领域技术人员可以理解的是，在用户输入的解锁信息与预存的解锁信息不匹配，且预设时间间隔内不匹配的次数大于预设阈值时，向预存的联系人信息所对应的终端发送提示信息。
本发明进一步提供一种智能电视终端。
参照图4，图4为本发明智能电视终端第一实施例的功能模块示意图。
需要强调的是，对本领域的技术人员来说，图4所示功能模块图仅仅是一个较佳实施例的示例图，本领域的技术人员围绕图4所示的智能电视终端的功能模块，可轻易进行新的功能模块的补充；各功能模块的名称是自定义名称，仅用于辅助理解该智能电视终端的各个程序功能块，不用于限定本发明的技术方案，本发明技术方案的核心是，各自定义名称的功能模块所要达成的功能。
本实施例提出一种智能电视终端，所述智能电视终端包括：
获取模块10，用于开机时，扫描终端所处的环境中的无线网络以获取当前无线网络信息；
在本实施例中，搜索模块10搜索终端所处的环境中的无线网络信号可在多种状态下执行，1)可在开机后，检测智能电视终端的无线网络开关是否开启，在无线网络开关未开启时，开启所述智能电视终端的无线网络开关；搜索智能电视终端所处的环境中的无线网络信号，以获取当前无线网络信息；2)在智能电视终端运行过程中定时搜索终端所处环境中的无线网络信号，以获取当前无线网络信息。
判断模块20，用于根据所述当前无线网络信息和所述终端中存储的基准无线网络信息判断终端所处的环境是否变化；
在本实施例中，根据所述当前无线网络信息和所述终端中存储的基准无线网络信息判断终端所处的环境是否变化可通过以下方式实现：
1)第一实施例，参照图5，所述判断模块20包括：
计算单元21，用于根据当前无线网络信息和基准无线网络信息计算环境安全系数；
判断单元22，用于根据环境安全系数判断所处环境是否发生变化。
所述计算单元21包括：
比对子单元，用于将预存的基准无线网络信息依次与获取到的无线网络信息进行比对，以确定基准无线网络信息与当前无线网络信息对应的网络标识以及信号权重；
计算子单元，用于将同一网络标识的信号权重进行与运算，并根据与运算结果计算各个网络标识对应的信任系数和变化值；
确定子单元，用于基于获取到的信任系数和变化值，确定搜索到的各个网络标识对应的无线网络信号的变化系数；
所述计算子单元，还用于对各个变化系数进行求和，得到当前环境安全系数。
其中，在没有基准无线网络信息与扫描到的无线网络信号的网络标识相同时，基准无线网络信息中，该网络标识对应的无线网络信息信号强度为0，即信号权重为0；在有基准无线网络信息与扫描到的无线网络信号的网络标识相同时，基准无线网络信息中，该网络标识对应的无线网络信息信号强度大于0，即信号权重为1。
例如，在当前搜索到的无线网络信息对应的信号强度大于0，且网络标识为A，则当前的信号权重L为1，在预存的基准无线网络信息中没有网络标识为A的基准网络信息时，网络标识为A的基准无线网络信息对应的信号强度为0，此时该网络标识为A基准无线网络信息对应的权重L″为0，当L&&L″＝＝0时，则P(信任系数)＝0.9，M(变化值)＝1，k(变化系数)＝0.9×1＝0.9；在当前搜索到的无线网络信息对应的信号强度大于0，且网络标识为A，则当前的信号权重L为1，在预存的基准无线网络信息中没有网络标识为A的基准网络信息，则网络标识为A的基准无线网络信息对应的信号强度大于0，即基准无线网络信息对应的权重L″为1，当L&&L″＝1时，则P(信任系数) ＝0.1，M(变化值)＝-1，k(变化系数)＝0.1×(-1)＝-0.1，则变化系数的计算公式为ki＝Pi×Mi，安全系数为各个变化系数的总和，即安全系数的计算公式为
Figure PCTCN2014095521-appb-000002
其中，K为安全系数，ki为各个网络信息对应的变化系数。
在当前环境安全系数小于等于零时，认为终端所处的环境变化，在当前环境安全系数大于零时，认为终端所处的环境未变化。
在本实施例中，上述权重值、信任系数以及变化值所对应的值为优选实施例，软件开发人员可根据需要上述值进行设定。
