Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present invention, and should not be construed as a limitation of the present invention.

These and other aspects of embodiments of the present invention will become apparent with reference to the following description and accompanying drawings. In these descriptions and drawings, some specific implementations of the embodiments of the invention are specifically disclosed to represent some ways of implementing the principles of the embodiments of the invention, but it should be understood that the scope of the embodiments of the invention is not limited by this limit. On the contrary, embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

The device pairing method in the embodiment of the present invention is suitable for interactive smart devices, such as interactive smart pads, which have wireless hotspots and can realize data interaction with terminal devices such as computers, mobile phones, and tablet computers through external devices. The external device is, for example, a wireless screen sharing device, which is used in conjunction with a USB screen sharing device. The wireless screen sharing device is generally connected to the interactive smart tablet through an HDMI cable or a VGA cable. The wireless screen sharing device obtains and configures the pairing parameters in the interactive smart tablet. The pairing parameters include the service set identifier and hotspot password information of the network connection of the smart interactive device. . When the USB screen sharing device matched with the wireless screen sharing device is inserted into the computer, the wireless screen sharing function is activated. connect. The computer and the interactive smart device are connected wirelessly through the external device, so that the screen in the computer can be projected onto the interactive smart device.

Referring to FIG. 1, the device pairing method in the first embodiment of the present invention is applied to the first system of interactive smart devices. The interactive smart device is, for example, an interactive smart tablet, including two systems running simultaneously, namely the first system A system and a second system. The method includes steps S11 to S13.

Step S11 , when the external device to be paired is detected, query whether the pairing parameters are stored locally, if yes, go to step S12 , otherwise go to step S13 .

Each system in the interactive intelligent device has a corresponding data connection interface, such as a USB, VGA interface, etc., for connecting an external device, such as a wireless screen sharing device. When the interactive smart device needs to use the terminal device computer or mobile phone for wireless screen sharing, insert the wireless screen sharing device into one of the systems of the interactive smart device. Any system in which an external device is currently inserted is referred to as a first system, and a system in which an external device is not inserted is referred to as a second system. When the first system can detect that an external device is inserted, it queries whether a pairing parameter paired with the external device is stored locally. The pairing parameter is, for example, the service set identifier and hotspot password information of the network connection of the intelligent interactive device. The external device can know the hotspot and the login password of the interactive smart device according to the service set identifier and the hotspot password information.

Step S12, sending the pairing parameter to the external device, so that the external device is paired with the first system according to the pairing parameter.

When the first system detects that pairing parameters, such as service set identifiers and hotspot password information, are stored locally, the pairing parameters are sent to the wireless screen sharing device connected thereto. The wireless screen sharing device receives and writes the pairing parameters sent by the first system. When the USB screen sharing device paired with the wireless screen sharing device is connected to the computer to start the wireless screen projection, the USB screen sharing device obtains the service set ID and hotspot password information of the interactive smart device, and connects the service set ID and hotspot password information according to the service set ID and hotspot password information. Enter the hotspot of the interactive smart device to realize wireless connection with the interactive smart device. Then, the data of the computer is wirelessly transmitted to the interactive smart tablet through the wireless screen sharing device and the USB screen sharing device.

Step S13: Acquire pairing parameters in the second system, and send the acquired pairing parameters to the external device, so that the external device is paired with the second system according to the pairing parameters.

When the first system queries that the pairing parameters are not stored locally, it means that the pairing parameters of the interactive smart device are set in the second system. The first system sends a request for acquiring pairing parameters to the second system through the dual-system communication protocol. After acquiring the request, the second system returns the pairing parameters to the first system through the dual-system communication protocol.

In this embodiment, the first system and the second system are both Android systems, which can be connected through an ADB (Android Debug Bridge, Android Debug Bridge) debug channel. The information transfer between systems is realized by ADB service. The two Android modules loaded with the first system and the second system respectively are physically connected through the USB, and the information between the two systems is transmitted through the USB interface. The two systems define a data transfer protocol. The data between the two systems is sent and received according to the agreed protocol format, and then parsed and processed to complete the corresponding logic.

It can be understood that the first system and the second system may be an Android system, a Windows Phone system (WP system), a Windows system, or an IOS system (an Apple mobile device operating system). The first system and the second system may be the same system or different systems.

When the first system receives the pairing parameters sent by the second system, it sends the pairing parameters to the external device, and the external device receives and writes the pairing parameters to complete the pairing with the interactive smart device.

It can be understood that the intelligent interactive device may include more than two systems, the system connected with the external device is the first system, and the other systems are the second system. When there are multiple second systems, the step for the first system to acquire the pairing parameters in the second system is specifically: the first system sends the request information for acquiring the pairing parameters to each of the second systems in sequence through a dual-system communication protocol , and receive the pairing parameters fed back by one of the second systems according to the request information.

In this embodiment, when the first system is connected to an external device, the first system inquires whether the pairing parameters are stored locally, and if not, obtains the pairing parameters in the second system across the systems, and sends the pairing parameters to the external device , so that the external device configures the pairing parameters to complete the pairing. Compared with the prior art, in this embodiment, the user can obtain the pairing parameters to complete the pairing regardless of which system the external device is connected to, which is convenient to use and enhances the user experience.

Referring to FIG. 2, the device pairing method in the second embodiment of the present invention is applied to the first system of interactive smart devices. The interactive smart device is, for example, an interactive smart tablet, including two systems running simultaneously, namely the A system and a second system. The method includes steps S21-S26.

Step S21, when an external device is detected, obtain identification information of the external device, and determine whether the identification information is preset identification information, if yes, go to step S22, otherwise go to step S25.

Step S22, query whether the pairing parameters are stored locally, if yes, go to Step S23, otherwise go to Step S24.

In step S23, a prompt message is issued to remind the user to insert the correct external device.

When the first system of the interactive smart device is connected to an external device, it is first necessary to determine whether the external device is a device to be paired, and when the external device is an external device to be paired, the step of querying whether the pairing parameters are stored locally is performed. If so, step S24 is directly executed, and if the external device is not the external device to be paired, a prompt message is issued, thereby avoiding unnecessary program execution. During specific implementation, the first system pre-stores a list of identification information of external devices that need to be configured. When an external device is connected to the first system, the first system obtains the identification information of the external device and compares it with the identification information list. to determine whether the identification information of the external device is preset identification information.

Step S24, sending the pairing parameter to the external device, so that the external device is paired with the first system according to the pairing parameter.

After receiving the pairing parameter, the external device writes the pairing parameter to the corresponding position to complete the pairing with the first system. For example, the external device is a wireless screen sharing device, and the corresponding pairing parameters include the service set identifier and hotspot password information. After the wireless screen sharing device is configured with the service set identifier and hotspot password information, it can enable the connected computer or mobile phone to realize intelligent interaction with it. Wireless communication between devices can display the screen of a computer or mobile phone on the screen of an intelligent interactive device.

Further, after the pairing parameters are sent to the external device, it is necessary to confirm whether the external device is paired successfully. The specific implementation includes the following steps:

Step S241, sending request information to the external device, where the request information is used to make the external device feed back pairing completion information.

Step S242, when the information fed back by the external device based on the request information is not obtained within a preset time, a prompt message is sent to remind the user that the pairing fails.

The first system polls and sends the request information to the external device at a preset time, and stops sending the request information until receiving confirmation information fed back by the external device according to the request information. When the confirmation information fed back by the external device is not obtained within the preset time, it is considered that the pairing fails, and the user checks the reason for the pairing failure. Generally, the pairing time between an external device and an intelligent interactive device is short, usually 2 to 10s. The preset time can be set according to actual needs, for example, it is set to 30s. When the pairing time exceeds 30s, a prompt message will be sent.

Step S25, acquiring the pairing parameter in the second system and the MD5 value of the pairing parameter, and verifying whether the pairing parameter is complete according to the MD5 value.

In the process of data transmission between systems, the pairing parameters may be lost or changed due to system instability or abnormal transmission, which affects the pairing. Therefore, when the first system acquires the pairing parameters in the second system, it is necessary to perform integrity verification on the pairing parameters. The MD5 value is a fixed-length value obtained by using the hash algorithm, which can be used to verify the integrity of the pairing parameters.

Step S26, when the pairing parameters are complete, send the pairing information to the external device, so that the external device is paired with the second system according to the pairing parameters.

It can be understood that when the first system sends the pairing parameters in the second system to the external device, the first system polls and sends the request information to the external device at a preset time until it receives the confirmation that the external device feeds back according to the request information. information, stop sending the requested information. When the confirmation information fed back by the external device is not obtained within the preset time, it is considered that the pairing with the second system has failed, and a prompt message is sent, so that the user can find the problem and check the cause of the pairing failure.

In this embodiment, when the external device is inserted into the first system of the interactive smart device, it is first determined whether the external device is a preset paired device, if so, the first system obtains its own pairing parameters, and if the first system is not paired If there is no pairing parameter in the first system, the pairing parameter in the second system will be acquired across the system, and the integrity of the pairing parameter acquired across the system will be checked, and a prompt will be issued if it is incomplete. Compared with the first embodiment, the present embodiment improves the pairing accuracy and pairing efficiency of the external device and the interactive smart device by checking the pairing parameters of the external device and acquired.
