Problems solved by technology

For technical personnel engaged in Internet of Things communication, there are too many configurable parameters, and it is difficult to grasp the selection of parameters and the selection of application functions
Data transmission through the above-mentioned protocol mainly has the following disadvantages: 1. The data transmission length field cannot be expanded, the data volume of the valid data transmitted is too small, and the network transmission efficiency is low; 2. For large data volume transmission, the organization of valid data (payload) There are defects in the method, and the efficiency of disassembling the package is low; 3. It is impossible to identify the repeated messages
[0004] For the problems existing in data transmission through the above protocols, no effective solutions have been proposed yet

Abstract

The invention provides a communication method and device for internet of things and relates to the technical field of communication of internet of things. The method comprises the step of generating amessage by an acquisition terminal according to acquired data information, wherein data structure of the message contains a message length field, a message number field, a maximum message number field and a variable structure qualifier field; field length of the message length field is at least two bytes; the message number field is used for defining the position of the current message in a message sequence, and the maximum message number field is used for defining the maximum number of the message sequence; the variable structure qualifier field at least contains a version number, and the version number is used for identifying the current message version and judging whether the current message version is valid or not; and the acquisition terminal sends the message to a control terminal.The communication method and device which are provided by the embodiment of the invention can better meet and adapt to network data transmission length requirement, and working efficiency and accuracyof transmission are improved.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things communication, and in particular, to an Internet of Things communication method and device. Background technique [0002] The Internet of Things (IOT, The Internet of Things) is an emerging information technology in recent years, and is considered to be another new information technology revolution after computers and the Internet. The combination of the Internet of Things and traditional industries has formed emerging industries, and the development of these industries relies on the development of information technology. The core link of information technology is the communication process. Only when the massive data collected is transmitted to the server, big data mining technology is meaningful, and the digitization and intelligence of the industry have a data foundation. Take the Agricultural Internet of Things as an example: At present, there are not many domestic manufactu...
