Embodiment Construction

[0024] The technical solution of the present invention will be described in detail below.

[0025] The basic idea of ​​the present invention uses a single data unit as the logical subject, and the main steps include:

[0026] Define data unit steps;

[0027] Define the same data flow structure steps at the sender and receiver;

[0028] Data stream grouping step;

[0029] Data flow sending and receiving steps;

[0030] The steps of data flow parsing.

[0031] Each step is described below.

[0032] 1. Define the data unit steps

[0033] The data unit is the minimum data body of the system defined in the present invention, which contains comprehensive information on the data to be transmitted, specifically, data name, data type (such as integer, character type, etc.), data length, correction coefficient and / or correction offset, Data parsing method, data internal code used for system to distinguish different data information.

[0034] For example, an air detection system n...

Abstract

The invention discloses a data-unit-based data transmission method. The data-unit-based data transmission method comprises the steps: defining a data unit; defining identical data flow structure bodies at a sending end and a receiving end; burstifying data flow; sending and receiving the data flow; analyzing the data flow. The data unit-based data transmission method has the beneficial effects that 1) an outer-space communication protocol achieves an agreement at the sending end and the receiving end, a data protocol is a fixed rule without the need of transmission and any expand; 2) the data structure bodies are defined simply, internal codes of each data unit and data of the data unit are paired to form independent data bodies, and when the structure bodies contain a plurality of data bodies, the ranking is not limited by a sequence; 3) the data bodies of the data structure bodies can be flexibly stretched and expanded as required.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a data unit-based data transmission method. Background technique [0002] Data communication is a communication method and communication service that uses data transmission technology to transfer data information between two terminals according to a certain communication protocol. It can realize data information transmission between computers and computers, computers and terminals, and terminals. [0003] In the prior art, the data communication protocol is the rules and conventions that must be followed for accurate and effective communication, but the adoption of the communication protocol has the following disadvantages: [0004] 1) The packaging protocol and parsing protocol must correspond strictly, otherwise parsing errors will result [0005] 2) Poor scalability: If the protocol increases or decreases items, the packaging protocol and parsing protocol must be updated at...
