显示设备1和交互平板4在实现传屏之前，无线传屏器3需要交互平板4进行配对，完成无线连接的建立。首次进行配对时，无线触屏器3需要插接到交互平板4上获取配对信息，后续才能根据配对信息进行配对。Before the display device 1 and the interactive tablet 4 realize screen sharing, the wireless screen sharing device 3 needs the interactive tablet 4 to be paired to complete the establishment of the wireless connection. When pairing is performed for the first time, the wireless touch screen device 3 needs to be plugged into the interactive tablet 4 to obtain pairing information, and then pairing can be performed according to the pairing information.
配对信息是指与交互平板建立通信连接所必须使用的信息，一般用于查找通信的对端设备，不同的通信方式对应不同的配对信息。通常情况下，该配对信息包括交互平板4的无线热点的信息和交互平板4的IP地址等，以无线热点为WiFi热点为例，该配对信息包括WiFi热点的名称和密码，WiFi热点的名称也称为WiFi热点的标识或者SSID，密码用作权限认证。Pairing information refers to the information that must be used to establish a communication connection with the interactive tablet, and is generally used to find the peer device for communication. Different communication methods correspond to different pairing information. Usually, the pairing information includes the information of the wireless hotspot of the interactive tablet 4 and the IP address of the interactive tablet 4, etc. Taking the wireless hotspot as the WiFi hotspot as an example, the pairing information includes the name and password of the WiFi hotspot, and the name of the WiFi hotspot also It is called the ID or SSID of the WiFi hotspot, and the password is used for authorization authentication.
现有技术中，当用户修改了交互平板的SSID和/或密码之后导致交互平板的WiFi信息变化，导致无线传屏器中已经写入的WiFi信息与交互平板当前的WiFi信息不一致，即无线传屏器中的配对信息失效，此时，无线传屏器仍然使用已经失效的配对信息与交互平板建立连接，导致传屏器无法连接到交互平板。In the prior art, when the user modifies the SSID and/or password of the interactive tablet, the WiFi information of the interactive tablet changes, and the WiFi information that has been written in the wireless screen sharing device is inconsistent with the current WiFi information of the interactive tablet. The pairing information in the screen monitor is invalid. At this time, the wireless screen sharer still uses the expired pairing information to establish a connection with the interactive tablet, resulting in the screen sharer being unable to connect to the interactive tablet.
此时，无线传屏器提示用户需要重新与交互平板配对，用户需要重新将无线传屏器插接到交互平板上，交互平板重新将新的配对信息写入无线传屏器，才能完成配对，上述配对方式繁琐。At this time, the wireless screen sharer prompts the user to re-pair with the interactive tablet, the user needs to re-plug the wireless screen sharer to the interactive tablet, and the interactive tablet rewrites the new pairing information into the wireless screen sharer to complete the pairing. The above pairing method is cumbersome.
为了解决现有技术中的问题，本申请提供一种无线传屏器的配对方法，无线传屏器能够发出一个特殊无线热点，该无线热点信息不能被用户修改，从而能够保证无线传屏器中写入的无线热点信息和交互平板的无线热点信息保持一致，不会发生由于无线热点信息被修改导致的热点失效问题。In order to solve the problems in the prior art, the present application provides a method for pairing a wireless screen sharer. The wireless screen sharer can send out a special wireless hotspot whose information cannot be modified by the user, thereby ensuring that the The written wireless hotspot information is consistent with the wireless hotspot information of the interactive tablet, and the problem of hotspot failure due to modification of the wireless hotspot information will not occur.
图2为本申请实施例一提供的无线传屏器的配对方法的流程图，如图2所示，本实施例提供的方法包括以下步骤。FIG. 2 is a flowchart of a method for pairing a wireless screen transmitter according to Embodiment 1 of the present application. As shown in FIG. 2 , the method provided by this embodiment includes the following steps.
S101、当无线传屏器与交互平板通过有线接口连接时，无线传屏器通过有线接口接收交互平板发送的配对信息，该配对信息包括交互平板发射的第一无线热点的信息，交互平板上存储的第一无线热点的信息不能被修改。S101. When the wireless screen sharer and the interactive tablet are connected through a wired interface, the wireless screen sharer receives pairing information sent by the interactive tablet through the wired interface, where the pairing information includes information of a first wireless hotspot transmitted by the interactive tablet, and is stored on the interactive tablet The information of the first wireless hotspot cannot be modified.
交互平板向无线传屏器中写入配对信息是通过有线方式写入的，无线传屏器与交互平板通过有线接口连接。一种实现方式中，无线传屏器可以通过插接的方式插接到交互平板；另一种实现方式中，无线传屏器通过连接线与交互平板连接，该连接线的两端分别连接无线传屏器的接口和交互平板的接口。The pairing information written by the interactive tablet into the wireless screen sharing device is written in a wired manner, and the wireless screen sharing device and the interactive tablet are connected through a wired interface.

本实施例中，交互平板发送的第一无线热点与普通的无线热点不同，现有的普通无线热点的信息用户可以通过交互平板进行修改，例如修改无线热点的SSID和/或密码，但是实施例中的第一无线热点的信息用户通过交互平板不能修改，或者说交互平板中存储的第一无线热点的信息不能修改。In this embodiment, the first wireless hotspot sent by the interactive tablet is different from the common wireless hotspot. The user can modify the information of the existing common wireless hotspot through the interactive tablet, for example, modify the SSID and/or password of the wireless hotspot, but the embodiment The user cannot modify the information of the first wireless hotspot in the interactive tablet, or the information of the first wireless hotspot stored in the interactive tablet cannot be modified.
本实施例中，可以通过如下两种方式实现第一无线热点的信息不能被用户修改。In this embodiment, the information of the first wireless hotspot cannot be modified by the user in the following two ways.
方式一，第一无线热点的名称和密码对用户是不可见的，可以在交互平板出厂时预置在设备中，用户无法获取到第一无线热点的名称和密码，从而也无法对第一无线热点的名称和密码进行修改，这样，第一无线热点相当于无线投屏器的私有热点，从而提高了网络安全性。Method 1, the name and password of the first wireless hotspot are invisible to the user, and can be preset in the device when the interactive tablet leaves the factory. The name and password of the hotspot are modified, so that the first wireless hotspot is equivalent to the private hotspot of the wireless screen projector, thereby improving network security.
方式二，第一无线热点的名称和密码交互平板出厂时预置在设备中，用户能够获取到第一无线热点的名称和密码，但是无法对第一无线热点的名称和密码进行修改。其他设备如果需要连接第一无线热点，需要手动输入第一无线热点的名称和密码才能完成连接。Method 2: The name and password of the first wireless hotspot is preset in the device when the interactive tablet leaves the factory, and the user can obtain the name and password of the first wireless hotspot, but cannot modify the name and password of the first wireless hotspot. If other devices need to connect to the first wireless hotspot, they need to manually input the name and password of the first wireless hotspot to complete the connection.
可选的，本申请实施例中，第一无线热点不能被周围设备扫描到，所以第一无线热点的名称不会显示在周围设备的无线列表中，第一无线热点也称为隐藏热点或者隐秘热点。Optionally, in this embodiment of the present application, the first wireless hotspot cannot be scanned by surrounding devices, so the name of the first wireless hotspot will not be displayed in the wireless list of surrounding devices, and the first wireless hotspot is also called a hidden hotspot or a hidden hotspot. hot spot.
可选的，交互平板还发射第二无线热点，该第二无线热点即普通无线热点，交互平板上存储的第二无线热点的信息能够被修改，且第二无线热点信息能够被周围设备扫描到。由于第二无线热点能够被周围设备扫描到，所以周围设备的无线列表中会显示第二无线热点的名称，如果第二无线热点设置了密码，用户可以通过输入密码连接到第二无线热点，如果第二无线热点没有设置密码，用户可以自动连接到第二无线热点。Optionally, the interactive tablet also transmits a second wireless hotspot, the second wireless hotspot is a common wireless hotspot, the information of the second wireless hotspot stored on the interactive tablet can be modified, and the information of the second wireless hotspot can be scanned by surrounding devices. . Since the second wireless hotspot can be scanned by the surrounding devices, the name of the second wireless hotspot will be displayed in the wireless list of the surrounding devices. If a password is set for the second wireless hotspot, the user can connect to the second wireless hotspot by entering the password. If The second wireless hotspot is not set with a password, and the user can automatically connect to the second wireless hotspot.
可以理解，该配对信息中除了第一无线热点的信息，还可以包括第一无线热点的IP地址或者其他信息，不同的无线方式中，该配对信息中包括的信息可能有差异。It can be understood that in addition to the information of the first wireless hotspot, the pairing information may also include the IP address or other information of the first wireless hotspot. In different wireless methods, the information included in the pairing information may be different.
交互平板中存储的第一无线热点的信息不能修改，从而能够保证无线传屏器中写入的无线热点信息和交互平板的无线热点信息保持一致，不会发生由于无线热点信息被修改导致的热点失效问题。从而能够避免由于交互平板的无线热点信息被修改，交互平板需要重新将配对信息写入无线投屏器，这样，一个交互平板只需要对无线投屏器进行一次配对信息写入，该配对信息一直有效，直至其他交互平板在该无效投屏器中写入新的配对信息，将该配对信息覆盖掉，从而简化了用户操作，用户不需要由于交互平板的无线热点信息被修改，而反复将交互平板和无线投屏器通过硬件接口连接在一起。The information of the first wireless hotspot stored in the interactive tablet cannot be modified, so that the wireless hotspot information written in the wireless screen sharing device can be kept consistent with the wireless hotspot information of the interactive tablet, and no hotspot caused by the modification of the wireless hotspot information will occur. failure problem. Therefore, it can be avoided that the interactive tablet needs to rewrite the pairing information into the wireless screen projector due to the modification of the wireless hotspot information of the interactive tablet. In this way, an interactive tablet only needs to write the pairing information to the wireless screen projector once, and the pairing information will always be written. It is valid until the other interactive tablet writes new pairing information in the invalid screen projector and overwrites the pairing information, thereby simplifying the user operation. The tablet and the wireless screen projector are connected together through a hardware interface.
