Internet-of-things communication method

Abstract

An Internet-of-things communication method of the invention enables a monitoring terminal to identify device data sent by a device terminal. The method comprises a device model building step in which each device terminal, after accessing a communication network, sends corresponding device metadata to a monitoring terminal to enable the monitoring terminal to generate a device model corresponding table, a sending rule setting step in which a user sets data sending rules between the device terminals and the monitoring terminal based on the network condition of the communication network, a data packet generating and sending step in which a sender among the device terminals and the monitoring terminal generates a data packet based on the data sending rules and sends the data packet to a receiver based on predetermined communication rules, and a data packet receiving and parsing step in which the receiver receives the sent data packet and parses the data packet to get corresponding data information, wherein the device metadata includes a device acquisition data item table, an acquisition task table and a device command table, and the monitoring terminal stores an identification number parsing table.

Description

technical field [0001] The invention relates to an Internet of Things communication method, in particular to an Internet of Things communication method that enables a monitoring terminal to identify device data of all device terminals. Background technique [0002] The concept of the Internet of Things is developed on the basis of the Internet, which extends and extends the user end to any item and item for information exchange and communication. The Internet of Things digitizes the real world and has a wide range of applications, including the following areas: transportation and logistics, health care, smart environments (home, office, factory), personal and social fields, etc., with a very broad market and application prospects. [0003] At present, it is mainly by embedding or installing information sensing modules such as sensors into field equipment such as power grids, railways, bridges, buildings, water supply systems, oil and gas pipelines, and industrial equipment,...

Problems solved by technology

However, due to the large number of manufacturers producing equipment, each manufacturer independently defines the data content transmitted in the produced equipment. Therefore, before the equipment is connected to the network, it needs to be individually parsed and configured in the cloud to obtain the data sent to the device after it is connected to the network. The data content in the cloud will lead to a long period of equipment network access; and, when there are more and more types of network equipment, the configuration of the cloud will be more cumbersome and consume a lot of resources

[0005] In addition, when the network resources of the Internet of Things are insufficient or the communication network is unstable, a large amount of data still needs to be sent, resulting in low network utilization
