Embodiment Construction

[0018] In one embodiment, refer to figure 1 , the present disclosure discloses a method for controlling an IoT device combining a block chain and a central server, including,

[0019] In a blockchain established by a consensus network, the first IoT device expands by registering with the central server to communicate with other registered IoT devices on the central server; the central server or MQTT message transfer server sends the first IoT The networked device information is written into the blockchain, and then each participating node jointly maintains the registered IoT device information recorded in the blockchain; when the mobile client and the first IoT device are in the same local area network, the mobile client and the first IoT device An IoT device performs a binding operation; the mobile phone client and any IoT device that has a binding relationship with it perform real-time communication of the IoT protocol through a shared MQTT message transfer server;

Abstract

The disclosure discloses an Internet of Things device control method combining a block chain and a central server. The Internet of Things device control method combining the block chain and the central server comprises the following steps: in the block chain established by a consensus network, the Internet of Things device expands through registering to the central server, so as to realize the communication with other registered devices; the central server or a MQTT message transfer server writes the information into the block chain, and then each participating node jointly maintains the device information recorded in the block chain; a mobile phone client (APP) and the device establish connection with the shared MQTT message transfer server through the Internet protocol after register, and then the APP and the Internet of Things device communicate in real time through the shared MQTT message transfer server with the Internet of Things protocol; and the device and the APP synchronize part of the data through CDN, and then write the own information to the block chain through the connected MQTT message transfer server.

Description

technical field [0001] The disclosure belongs to the technical field of Internet of Things communication, and in particular relates to a method for controlling an Internet of Things device combining a block chain and a central server. Background technique [0002] The Internet of Things is a network that extends and expands on the basis of the Internet, and its users extend to items and items. At present, the centralized technical architecture is popular in the Internet of Things, and the communication and data storage of Internet of Things devices rely on centralized servers to complete. There are some problems with this architecture: [0003] 1. When there are many devices, the central server will face the problem of data congestion. [0004] 2. Once there is a problem with the central server, the IoT devices mounted on it will have communication failures at the same time. [0005] 3. If the distance between devices is relatively long, the real-time performance of commu...
