in this embodiment, whether the query result is obtained to obtain the IP address of the mobile phone device of the IOS system or not is determined, and whether the IP data of the mobile phone of the IOS system has been found or not can be determined by data information fed back by the mDNS protocol. If the returned result is null, it indicates that no related device is accessed in the WiFi network, and if the returned result is yes, it indicates that the data server to be matched exists in the WiFi network at present. In one embodiment, the data server to be matched may not be unique, and a free matching mode may be selected, and the present invention may traverse all servers according to a certain algorithm and filter out the servers that can be matched. In another embodiment, the searched data servers may be arranged in a list form, and matching is performed after the selection operation of the person is received.
103. If the query cannot be carried out, the data server based on the IOS system is queried again in the local area network;
in this embodiment, if the returned result is { Null }, the search is performed again on the connected WiFi network. In another embodiment, the unsearched local area networks may be discarded and all local area networks that can be searched in the location may be connected in turn.

105. According to the pairing result, sending a connection verification instruction to the data server, and receiving first verification feedback information fed back by the data server;
in this embodiment, after the pairing result is qualified, the pair-verify instruction based on the HomeKit protocol sends a connection verification instruction to the IP address { 192.168.3.98255.255.255.1 } of the mobile phone device of the IOS system, where the connection verification instruction includes a connection number: XXSA! | A @ # 1224. According to connection number XXSA! | A @ #1224 matches the first validation feedback information fed back by the handset device of the IOS system.
106. Processing the first verification feedback information by using a preset feedback analysis rule to generate second verification feedback information;
in this embodiment, first verification feedback information fed back by the mobile phone device is obtained, the first verification feedback information is analyzed based on a rule of the HomeKit protocol, whether the first feedback information meets the requirement that the first feedback information is qualified is judged, then second verification feedback information is generated based on the first feedback information is qualified, the first verification feedback is completed based on a pair-verify instruction of the HomeKit protocol of the TCP/IP protocol, and the process cannot be realized by a common TCP/IP protocol.
107. And establishing data transmission connection with the data server according to the second verification feedback information to obtain a transmission channel with the data server.
In this embodiment, a pair-verify instruction based on the HomeKit protocol establishes a transmission connection with the mobile phone device of the IOS system according to the second verification feedback information, receives the returned data instruction through the initial instruction sent by the AirPlay or RAOP protocol, and finally completes establishment of the transmission channel. And the screen projection process of the non-IOS system to the IOS system data is realized by completing the establishment of channel transmission. When a channel is established, the conventional TCP/IP protocol cannot be used for signal communication due to the closed characteristic of the IOS system. The non-IOS system of the invention can be an operating system such as Android, Linux, Windows and the like.
In the embodiment of the invention, the matched IOS system data is projected to the display screen of the non-IOS system by using the DNS protocol technology in the local area network, so that the technical problem that the IOS system cannot project the screen in the non-IOS system is solved.
