Data transmission method of Internet of Things

Abstract

The invention provides a data transmission method of the Internet of Things. The Internet of Things comprises four nodes: a data router, user equipment, a sensor node and an execution node; the data router is used for route forwarding, the user equipment is a data consumer and is used for obtaining data sensed by the sensor node or releasing a command to the execution node to realize remote control, and the sensor node and the data node are data providers; a user can inquire parameters of an environment where a target object node is located in real time by using the method, and can send the command to the sensor node according to the state of the target object node to realize the real-time control and adjustment of the target object node, and the data transmission method provided by the invention can be widely used in agricultural environmental monitoring, remote control and other fields.

Description

technical field [0001] The present invention relates to a data transmission method, in particular to an Internet of Things data transmission method. Background technique [0002] In a typical IoT architecture, an electronic tag has a globally unique electronic code, which is attached to an item to identify the target object. During the life of the item, the reader uses radio frequency identification technology (RFID, Radio-frequency identification) to read the electronic tag attached to the target object and sends the electronic code to the IoT middleware, and the IoT middleware will identify the electronic code. The target object information data is transmitted to the remote database server for storage or updating. The user queries the relevant information of the target object by sending the electronic code of the item to the Internet of Things middleware, and the Internet of Things middleware sends the electronic code of the target object to the object name resolution ser...

AI Technical Summary

Problems solved by technology

[0004] 1) The user can only obtain the target object information through the database server, and cannot realize direct point-to-point communication with the target object;

[0005] 2) The user can only query the information of the target object, and cannot directly control the state of the target object;

[0006] 3) The target object information can only be read passively through the reader, and the target object cannot actively request data updates or send out alarm information according to the current state
