Description

Data communication method, device and system

Technical Field

The present invention relates to the field of communications, and in particular, to a data communication method, apparatus, and system.

Background

Currently, a client (e.g., a smart phone Application (APP)) in the related art needs to establish communication with an embedded wireless communication component (e.g., a wireless fidelity (Wi-Fi) component) in a server to meet a specific requirement or achieve a specific purpose. Fig. 1 is a flowchart of a process of establishing communication between a Client and an embedded wireless communication component in a Server according to the related art, where as shown in fig. 1, a smart phone APP serves as a Client (Client) of a Transmission Control Protocol (TCP) connection, and a Wi-Fi component of a smart device serves as a Server (Server) of the TCP connection, the process may include the following steps:

step S102, the intelligent device Wi-Fi assembly starts a local area network Access Point (AP) and starts a Server program to wait for a Client to connect;

step S104, the smart phone APP accesses the AP successfully;

step S106, the smart phone APP serves as a Client and initiates a connection request to a Server through Server address information (ServerIP) and Server port information (ServerPort) agreed by a pre-protocol;

and step S108, the connection between the Client terminal and the Server terminal is successfully established, and communication is started.

However, the above communication interaction flow has the following technical drawbacks:

(1) after the 4G network is opened to the smart phone of some models, the connection request that smart phone APP sent can't reach smart machine Wi-Fi subassembly to lead to the LAN connection failure between smart phone APP and the smart machine Wi-Fi subassembly, its leading cause lies in: after the 4G network is started, if the local area network AP started by the Wi-Fi component of the intelligent device is connected again, the 4G network channel is used by default for network communication.

(2) The smart phone produced by a particular manufacturer may default to closing or prohibiting the network port of the smart phone, thereby causing a failure in the local area network connection between the smart phone APP and the smart device Wi-Fi component.

(3) The Internet Protocol (IP) address of the Wi-Fi component of the intelligent device is relatively fixed, and the safety of the Wi-Fi component is poor.

(4) Under a mixed channel (2.4G/5G) Wi-Fi router, a smart device Wi-Fi component adopting a 2.4G channel cannot establish TCP connection with a smart phone APP and complete service communication.

In view of the above problems, no effective solution has been proposed.
