Problems solved by technology

Therefore, for a heterogeneous smart home system, the complexity of the user's home management and control is relatively high; in addition, the existing smart home devices lack security considerations in the design of communication protocols, and data The privacy protection is not enough. Once the communication protocol is cracked, the attacker can remotely manipulate any home device in any home

[0053] figure 1 It is a flow chart of a data transmission method in the first embodiment of the present invention. The method in this embodiment can be executed by a data transmission system. The system can include a server, a centralized control device, and at least two receiving devices, and is installed in a mobile Client interaction within the terminal. The method of this embodiment is specifically executed by the server, including the following steps:

[0054]Step 110, establishing a TCP (Transmission Control Protocol, Transmission Control Protocol) connection for the client that has passed the security verification.

[0055] In this embodiment, the user of the smart home system can use the client (for example: smart home control software) installed in the mobile terminal (for example: smart phone, tablet computer, etc.) Send corresponding control commands. When the server detects the client's access request, it will establish a TCP connection for the client that has p...

Abstract

The invention discloses a data transmission method and a data transmission system. The method includes: establishing a Transmission Control Protocol TCP connection for a client that has passed security verification; obtaining a Hypertext Transfer Protocol HTTP request in the encrypted information sent by the client through the TCP connection; according to the HTTP request, obtaining Corresponding control information, wherein the control information includes the identification of the equipment to be operated and the type of operation; look up the operation correspondence table to obtain the standard operation instruction corresponding to the control information; combine the identification of the equipment to be operated with the standard operation instruction sent to the centralized control device. The invention reduces the direct interaction between the user and the smart home equipment, enhances the safety and reliability of the smart home equipment, reduces the complexity of user management and use of heterogeneous smart home equipment, and improves the management of smart home system availability.
