Description

Technical Field

[0001] The present invention relates to distribution network technology, and particularly to a contactless distribution network system and method based on NFC. Background Art

[0002] With the rapid development of Internet of Things technology, smart gateways and Internet of Things devices have been widely popularized. As the core device of a home network, a smart gateway plays an important role in connecting to the Internet and managing Internet of Things devices within the home. However, there are many problems in the network access configuration process of existing smart gateways and Internet of Things devices, seriously affecting the user experience and the installation and maintenance efficiency.

[0003] Currently, the network access configuration of smart gateways is usually based on the http / https protocol. Installation and maintenance personnel need to connect to the local area network of the smart gateway through wired or wireless means and log in to its configuration interface for manual settings. This process is not only complex in operation but also time-consuming, increasing the workload of installation and maintenance personnel. For ordinary users, the networking process of Internet of Things devices is also cumbersome. Most Internet of Things devices require users to manually enter information such as WiFi passwords to connect to the home network, which is difficult for users not familiar with technology and easily leads to configuration failures, thus affecting the user experience of smart devices.

[0004] In addition, the existing networking processes of smart gateways and Internet of Things devices lack a unified standard. Different brands and models of devices often require different configuration methods, which not only increases the learning cost for users but also brings many inconveniences to the management and maintenance of devices. In terms of security, there are also certain hidden dangers in the existing configuration processes. Due to the lack of effective authentication and encryption mechanisms, illegal devices may access the network, thus threatening user privacy and network security.

[0005] Therefore, there is an urgent need for a distribution network solution that can simplify the network access processes of smart gateways and Internet of Things devices, and improve the installation and maintenance efficiency and user experience. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: to propose a contactless distribution network system and method based on NFC to simplify the network access processes of smart gateways and Internet of Things devices, and improve the installation and maintenance efficiency and user experience.

[0034] Further, in step A3, before the gateway device sends its own device information to the installation and maintenance terminal, it encrypts the device information.

[0035] Further, in step B3, before the gateway device sends the WiFi configuration information to the Internet of Things device, it encrypts the WiFi configuration information.

[0036] Further, the WiFi configuration information includes the SSID and password of the WiFi network.

[0037] Further, the network access configuration information includes the password and network configuration required for the gateway device to access the Internet.

Whether the installation and maintenance personnel configure the intelligent gateway or the user adds the Internet of Things device, it can be completed through the same NFC touch method, making the entire network connection process more standardized and user-friendly.

Specifically, when configuring the gateway device, the installation and maintenance personnel only need to touch the NFC module of the intelligent gateway with a terminal with NFC function to trigger the network configuration process. After the installation and maintenance terminal sends a network configuration request to the gateway device, the gateway device authenticates the network configuration request. After the authentication passes, it sends its own device information to the installation and maintenance terminal. Then, the installation and maintenance terminal obtains the corresponding network access configuration information according to the device information of the gateway device and sends it to the gateway device. Finally, the gateway device receives the network access configuration information and completes its own network access configuration. When configuring the networking of Internet of Things devices, the user only needs to touch the NFC module of the Internet of Things device with the NFC module of the gateway device to automatically trigger the networking configuration process. After the Internet of Things device sends a networking request to the gateway device, the gateway device authenticates the networking request. After the authentication passes, it sends WiFi configuration information to the Internet of Things device. Finally, the Internet of Things device receives the WiFi configuration information and completes the networking configuration.
