Description

用于无线传屏设备的连接方法、无线传屏设备及显示设备 技术领域
本发明实施例涉及电子技术，尤其涉及一种用于无线传屏设备的连接方法、无线传屏设备及显示设备。
背景技术
随着电子技术的不断发展，无线传屏设备及其交互显示设备被广泛应用于教学、会议等活动中，其主要功能是将电脑上屏幕显示的内容显示到交互显示设备的屏幕中，以便于其他用户观看。智能手机的加入使得传屏交互系统可以通过特殊的传屏APP(Application，软件)采集手机上的屏幕，此时只需要手机与交互显示设备的无线热点相连接就能实现传屏功能，但与此同时也带来一个不可避免的问题：当手机用户连接过交互显示设备的无线热点，就会自动记忆该热点的SSID(Service Set Identifier，服务集标识)和密码，由于同一个交互显示设备的无线热点SSID和密码是固定不变的，从而导致下次进入该热点的范围内时无论需不需要连接，手机都会自动连接上该交互显示设备的无线热点。
为了防止手机用户误连，目前采用的技术方案是手动对密码进行更新设置或者手动断开手机的无线连接。而其缺陷在于，当密码更新后又需要重新配对设备，使得操作不便，不能在无需重新配对设备的情况下有效防止其他设备的误连。
发明内容
有鉴于此，本发明实施例提供一种用于无线传屏设备的连接方法、无线传屏设备及显示设备，以简化配对操作，防止其他设备误连。
第一方面，本发明实施例提供了一种用于无线传屏设备的连接方法，该方法包括：
根据预设字段搜索并获取目标显示设备的无线热点名称，所述无线热点名称包括所述预设字段和编码字段；
根据所述无线热点的编码字段确定所述目标显示设备的无线热点登录密码；
根据所述无线热点名称与所述无线热点登录密码建立与所述目标显示设备的无线连接。
第二方面，本发明实施例还提供了一种用于无线传屏设备的连接方法，该方法包括：
生成无线热点名称；
向无线传屏设备发送所述无线热点名称，所述无线热点名称包括预设字段和编码字段，使所述无线传屏设备根据所述预设字段搜索并获取所述无线热点名称，再根据所述无线热点名称中的编码字段确定所述无线热点登录密码，并建立与所述无线热点的连接。
第三方面，本发明实施例还提供了一种无线传屏设备，该设备包括：
名称获取单元，用于根据预设字段搜索并获取目标显示设备的无线热点名称，所述无线热点名称包括所述预设字段和编码字段；
密码确定单元，与所述名称获取单元相连，用于根据所述无线热点的编码字段确定所述目标显示设备的无线热点登录密码；
无线连接单元，与所述名称获取单元和密码确定单元相连，用于根据所述 无线热点名称与所述无线热点登录密码建立与所述目标显示设备的无线连接。
第四方面，本发明实施例还提供了一种显示设备，该设备包括：
名称生成单元，用于生成无线热点名称；
名称发送单元，与所述名称生成单元相连，用于向无线传屏设备发送所述无线热点名称，所述无线热点名称包括预设字段和编码字段，使所述无线传屏设备根据所述预设字段搜索并获取所述无线热点名称，再根据所述无线热点名称中的编码字段确定所述无线热点登录密码，并建立与所述无线热点的连接。
本发明实施例根据预设字段获取目标显示设备的无线热点名称，再根据该无线热点名称中的编码字段确定无线热点登录密码，从而建立与目标显示设备的无线连接，解决了现有技术中因需要手动设置无线热点密码而导致的操作不便且无法自动防止其他设备误连的问题，实现了简化配对操作，防止其他设备误连的效果。

目标显示设备可以是交互平板、智能白板等具有无线热点和支持传屏功能的智能终端。示例性的，交互平板发出的SSID“seewo_1234567”中预设字段为“seewo”，当无线传屏设备搜索到接收范围内的无线热点名称中有“seewo”字段，即获取该无线热点的SSID，其中“1234567”为编码字段。
S120、根据无线热点的编码字段确定目标显示设备的无线热点登录密码。
具体的，无线热点的编码字段可设置在预设字段之后，与预设字段共同组成目标显示设备的无线热点名称，且编码字段可以是根据目标显示设备的无线热点登录密码经过加密算法进行加密后得到的一系列字符。其中，无线热点登录密码和/或加密算法可以是动态变化的。设置编码字段的目的在于，只允许特定设备连接此目标显示设备的无线热点，避免出现其他设备例如手机连接过目标显示设备后，第二次进入该无线热点范围内时自动连接，从而造成误连的情况。
具体的，根据无线热点的编码字段确定目标显示设备的无线热点登录密码的过程可以是对编码字段进行解密的过程，与目标显示设备利用加密算法对无线热点登录密码进行加密的过程是相反的。示例性的，交互平板采用加密算法对无线热点登录密码进行加密，形成编码字段，无线传屏设备根据无线热点名称中携带的编码字段利用与加密算法对应的解密算法对无线热点登录密码进行 解密，得到交互平板的无线热点登录密码。
S130、根据无线热点名称与无线热点登录密码建立与目标显示设备的无线连接。
具体的，根据接收范围内获取到的目标显示设备的无线热点名称，以及解密得到的目标显示设备的无线热点登录密码，即可自动完成与目标显示设备的无线连接，这样设置的好处在于，即使目标显示设备的无线热点登录密码发生改变，也可以实现自动建立与目标显示设备的无线连接，从而简化了与目标显示设备的配对操作。
示例性的，无线传屏设备在与电脑通过USB(Universal Serial Bus，通用串行总线)接口连接后，利用获取到的交互平板的无线热点名称以及解密得到的目标显示设备的无线热点登录密码，即可与交互平板建立无线连接，从而将电脑屏幕通过无线连接传输至该交互平板，使得交互平板能够显示该电脑屏幕，完成传屏过程。
本实施例的技术方案，根据预设字段获取目标显示设备的无线热点名称，再根据该无线热点名称中的编码字段确定无线热点登录密码，从而建立与目标显示设备的无线连接，解决了现有技术中因需要手动设置无线热点密码而导致的操作不便且无法自动防止其他设备误连的问题，实现了简化配对操作，防止其他设备误连的效果。
实施例二
图2为本发明实施例二提供的一种用于无线传屏设备的连接方法的流程示意图。本实施例以上述实施例为基础进行优化，提供了优选的用于无线传屏设 备的连接方法，具体是，将根据预设字段搜索并获取目标显示设备的无线热点名称包括：搜索在连接范围内的无线热点名称；获取包含预设字段的无线热点名称。
S210、搜索在连接范围内的无线热点名称。
具体的，连接范围与终端的接收范围以及目标显示设备的无线热点发送范围有关。在搜索无线热点时，连接范围内可能会出现多个无线热点名称，此时可根据无线热点的信号强度的大小进行排列。
S220、获取包含预设字段的无线热点名称。
具体的，若搜索到连接范围内只有一个包含预设字段的无线热点名称，则直接获取该无线热点名称；若搜索到连接范围内有至少两个包含预设字段的无线热点名称，则获取其中包含预设字段且信号强度最大的无线热点名称。
示例性的，若无线传屏设备搜索到连接范围内只有一个包含“seewo”的SSID，则获取该无线热点所对应的交互平板的SSID；若无线传屏设备搜索到连接范围内有两个包含“seewo”的SSID，则获取其中信号强度较大的无线热点所对应的交互平板的SSID。
S230、根据无线热点的编码字段确定目标显示设备的无线热点登录密码。
S240、根据无线热点名称与无线热点登录密码建立与目标显示设备的无线连接。
本实施例的技术方案，通过搜索连接范围内的无线热点名称并获取其中包含预设字段的无线热点名称，再根据该无线热点名称中的编码字段确定无线热点登录密码，从而建立与目标显示设备的无线连接，解决了现有技术中因需要手动设置无线热点密码而导致的操作不便且无法自动防止其他设备误连的问 题，实现了简化配对操作，防止其他设备误连的效果。
实施例三
图3为本发明实施例三提供的一种用于无线传屏设备的连接方法的流程示意图。本实施例以上述各实施例为基础进行优化，提供了优选的用于无线传屏设备的连接方法，具体是，将根据无线热点的编码字段确定目标显示设备的无线热点登录密码进一步优化为，包括：获取无线热点名称中的编码字段，编码字段为无线热点登录密码按照预设编码方式进行编码得到的字段；将编码字段按照与预设编码方式相对应的解码方式进行解码，并确定解码出来的字段为目标显示设备的无线热点登录密码。
S310、根据预设字段搜索并获取目标显示设备的无线热点名称，无线热点名称包括预设字段和编码字段。
S320、获取无线热点名称中的编码字段，编码字段为无线热点登录密码按照预设编码方式进行编码得到的字段。
可选的，无线热点名称中的预设字段与编码字段通过某个标识符连接，例如无线热点名称为16位，则前5位为预设字段，即“seewo”，后10位为编码字段，即“0123456789”，预设字段与编码字段中间设置有下划线，所以无线热点名称为“seewo_0123456789”，即根据标识符即可确定并获取热点名称中的编码字段。
具体的，预设编码方式可以是固定不变的，即在目标显示设备出厂时就设定好的加密算法，例如可以是简单的移位算法或加减乘除算法，也可以是某种特殊的加密算法，加密后得到的编码字段位数只需满足预设的要求位数即可， 具体的算法种类在此不作限定。而编码字段则是由无线热点登录密码根据该预设编码方式进行编码，从而得到的特殊字段。示例性的，当无线热点登录密码为“0123456789”，且预设编码方式为向右循环移一位时，则编码字段为“9012345678”。
S330、将编码字段按照与预设编码方式相对应的解码方式进行解码，并确定解码出来的字段为目标显示设备的无线热点登录密码。
相应的，解码方式为编码方式的逆运算，将编码字段进行解码，即可经过编码方式的逆运算得到目标显示设备的无线热点登录密码。示例性的，若编码字段为“9012345678”，且预设编码方式为向右循环移一位时，则解码方式设为向左循环移一位，因此解码出来的字段为“0123456789”，即为交互平板的无线热点登录密码。
具体的，由于对于同一目标显示设备而言，无线热点登录密码是随机可变的，因此该编码字段也随着无线热点登录密码的改变而改变，即相对于需要连接目标显示设备的其他设备而言，无法通过历史登录记录从而直接与该目标显示设备建立无线连接。
S340、根据无线热点名称与无线热点登录密码建立与目标显示设备的无线连接。
本实施例的技术方案，根据预设字段获取目标显示设备的无线热点名称，再将从无线热点名称中获取的编码字段，按照与预设编码方式相对应的解码方式进行解码，得到无线热点登录密码，从而建立与目标显示设备的无线连接，解决了现有技术中因需要手动设置无线热点密码而导致的操作不便且无法自动防止其他设备误连的问题，实现了简化配对操作，防止其他设备误连的效果。
实施例四
图4为本发明实施例四提供的一种用于无线传屏设备的连接方法的流程示意图。本实施例以上述各实施例为基础进行优化，提供了优选的用于无线传屏设备的连接方法，具体是，将无线热点名称进一步优化为，还包括编码方式字段。
S410、根据预设字段搜索并获取目标显示设备的无线热点名称，无线热点名称包括预设字段、编码字段和编码方式字段。
具体的，编码方式字段可以与预设字段和编码字段一起设置在无线热点的名称中，通过标识符进行连接，例如对于交互平板中的具有16位的SSID，其预设字段、编码方式字段和编码字段通过下划线连接，即SSID为“seewo_a_81234567”，其中预设字段为“seewo”，编码方式字段为“a”，编码字段为“81234567”。
S420、获取无线热点名称中的编码方式字段以及编码字段。
其中，编码方式字段对应于特定编码方式，编码字段为无线热点登录密码按照特定编码方式进行编码得到的字段。
具体的，编码方式字段可以设置为特定编码方式的标识符，即一种编码方式字段对应于一种编码方式，例如：若编码方式字段设置为“a”，则表示编码方式为向右循环移一位；若编码方式字段设置为“b”，则表示编码方式为向右循环移两位。
具体的，编码方式字段可以随目标显示设备的重启而动态改变，即同一个显示设备可以设置不同的编码方式字段并分别对应不同的编码方式，编码方式字段随着显示设备的重启而改变。
S430、将编码字段按照特定编码方式相对应的解码方式进行解码，并确定解码出来的字段为目标显示设备的无线热点登录密码。
具体的，将编码字段按照编码方式字段对应的特定编码方式的逆运算进行解码。示例性的，若交互平板的SSID“seewo_a_81234567”中编码方式字段设置为“a”，其对应的特定编码方式为向右循环移一位，则无线传屏设备对获取的编码字段“81234567”进行解码时，按照与特定编码方式相对应的解码方式即向左循环移一位，得到解码出来的字段为“12345678”，此时，可确定该交互平板的无线热点登录密码为“12345678”。设置编码方式字段的好处在于，即使目标显示设备的无线热点登录密码不是动态改变的，由于解码方式是动态改变的，也会生成不同的无线热点登录名称，从而避免其他设备通过历史登录记录造成误连的情况，同时，需要连接目标显示设备的特殊设备例如无线传屏设备，也不会因为无线热点登录密码动态改变而出现需要手动登录等复杂操作才能建立无线连接的情况，简化了特殊设备与目标显示设备之间建立无线连接的操作。
S440、根据无线热点名称与无线热点登录密码建立与目标显示设备的无线连接。
本实施例的技术方案，通过获取目标显示设备发出的无线热点名称中的编码方式字段以及编码字段，将编码字段按照与编码方式字段代表的特定编码方式相对应的解码方式进行解码，得到无线热点登录密码，从而建立与目标显示设备的无线连接，解决了现有技术中因需要手动设置无线热点密码而导致的操作不便且无法自动防止其他设备误连的问题，实现了简化配对操作，防止其他设备误连的效果。
实施例五
图5为本发明实施例五提供的一种用于无线传屏设备的连接方法的流程示意图。该方法可适用于无线连接的情况，该方法可以由无线连接装置来执行，该装置可由硬件和/或软件组成，且一般可集成在显示设备以及所有包含接收无线传屏功能的终端中。具体包括如下：
S510、生成无线热点名称。
具体的，在设备重启的过程中，动态生成一组随机数作为无线热点登录密码，按照预设的编码方式将该动态生成的无线热点登录密码进行编码，生成编码字段，最后将预设字段和编码字段通过标识符连接起来，生成该设备的无线热点名称。示例性的，在交互平板重启的过程中，动态生成一组随机数，例如“12345678”，按照预设的编码方式，例如将密码向右循环移两位，生成编码字段“78123456”，将预设字段“seewo”与编码字段“78123456”通过下划线连接起来，生成该交互平板的SSID即“seewo_78123456”。可选的，该无线热点名称中还包括编码方式字段“a”，则生成的SSID为“seewo_a_78123456”。编码方式字段所对应的编码方式可以通过建立编码数据库相应地进行存储，当显示设备重启时，根据不同的编码方式字段通过调用编码数据库生成对应的无线热点名称。相应地，在无线传屏设备端也设置同样的与编码方式字段对应的解码数据库，且编码数据库与解码数据库中存储的编码方式与解码方式在编码方式字段相同的情况下互为逆运算。
S520、向无线传屏设备发送无线热点名称。
其中，无线热点名称包括预设字段和编码字段，使无线传屏设备根据预设字段搜索并获取无线热点名称，再根据无线热点名称中的编码字段确定无线热 点登录密码，并建立与无线热点的连接。
具体的，可通过wifi模块发送无线热点名称，向处于该无线信号的覆盖范围内的无线传屏设备发送无线热点名称。
本实施例的技术方案，通过生成并向无线传屏设备发送无线热点名称，使无线传屏设备根据预设字段搜索并获取无线热点名称，再根据无线热点名称中的编码字段确定无线热点登录密码，并建立与无线热点的连接，解决了现有技术中因需要手动设置无线热点密码而导致的操作不便且无法自动防止其他设备误连的问题，实现了简化配对操作，防止其他设备误连的效果。
