Method for adding device to network through visible light

Abstract

The invention relates to a method for adding a device to a network through visible light. The method involves a visible light transmitting device, a device to be added to the network and the specific network. The device to be added to the network is powered on and then conducts self-inspection, and is automatically switched to be in a visible light receiving mode after self-inspection is finished; after the device to be added to the network receives light signals, the network address of the specific network is acquired through decoding by a main control MCU; after receiving information from the device to be added to the network, the specific network sends confirmation information to the device to be added to the network; after receiving the confirmation information from the specific network, the device to be added to network is added to the specific network. Through the method, multiple devices can be networked at the same time, the networking process is simplified, any device with a flash lamp such as a mobile phone, a tablet computer and other devices can be used as a transmitting device, special visible light transmitting devices are not needed, networking efficiency is improved, and networking steps are simplified.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for adding equipment to a network by using visible light. Background technique [0002] At present, in the field of visible light communication, there are few methods involving visible light to build a home network: [0003] Beijing University of Posts and Telecommunications proposed a broadband access device and method based on visible light communication (patent number: 201210236047.9). This method modulates broadband signals onto wireless optical carriers, and completes the transmission of data services while using LEDs for lighting. Internet-connected devices can access the Internet through visible light communication. This method is only applicable to computer networking, and is not applicable to the networking of home intelligent systems.

[0004] The Institute of Semiconductors of the Chinese Academy of Sciences has disclosed a visible light communication control system and its implementation method. This method proposes to use the visible light signal sending device, the visible light signal receiving device and the main control device to carry out smart home networking. In this method, The sending device of the visible light signal used is a white light LED, and the LED light of the mobile device cannot be used as the sending device. It uses a fixed device to control the device network, which greatly reduces the flexibility of the network.

[0005] Chinese patent 201010267738.6 proposes a smart home control system and method using power lines and remote controllers to form a network. This method is also limited by the control equipment, and the remote controller must be used to transmit control signals to the controlled equipment, which cannot be done through existing equipment. Control and flexible networking issues have not been resolved

At present, there are mainly two methods for adding control devices to the home network: one is that the network host automatically searches for new devices within the radiation range of the home network, and repeatedly confirms them through a series of complex protocols. The disadvantage of this method is It is impossible to judge whether the newly added device is the device that the user needs to add, and it is easy to add it by mistake; the second method is to add a specific device to the network by scanning the QR code information carried by the device itself or manually entering the device number on the computer. The reliability of this method is better, but the operation is complicated
