Embodiment Construction

[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0030] The present invention provides a kind of data transmission control method of ZigBee network terminal node, this ZigBee network data transmission control method comprises:

[0031] Step 1, calculate and obtain the data transmission time of the k terminal nodes of the ZigBee network by the following formula,

[0032] Among them, T is the preset period value, k is the terminal node number; t Endk is the original sending time of the terminal; n is the number of terminal nodes, and n is greater than or equal to 2;

[0033] Step 2, starting from the second terminal node, judge whether the sending time interval between each subsequent terminal node and all t...

Abstract

The invention discloses a data transmission control method, a communication system and a machine readable storage medium, and the method comprises the steps: 1, obtaining the data transmission time ofk terminal nodes of a ZigBee network through the calculation of the following formula, wherein T is a preset period value, and k is the number of the terminal nodes; the tEndk is the original sendingtime of the terminal; n is the number of terminal nodes, and n is greater than or equal to 2; 2, sequentially judging whether the sending time interval between each subsequent terminal node and all previous terminal nodes is greater than preset time or not by starting from the second terminal node; under the condition that the sending time interval between each subsequent terminal node and all previous terminal nodes is greater than first preset time, controlling the terminal nodes to execute sending at the original sending time; and 3, repeating the step 2 to obtain the sending time of all the terminal nodes. According to the invention, the problem of too high packet loss rate during data transmission can be avoided, and the packet loss rate is avoided while congestion is avoided.

Description

technical field [0001] The present invention relates to the field of network transmission, in particular to a data transmission control method, a communication system and a machine-readable storage medium. Background technique [0002] In the point-to-point communication of ZigBee, if the terminal node transmits data, the CSMA-CA mechanism is generally used to deal with the problem of data congestion, but the above-mentioned method cannot solve the packet loss rate of data. [0003] How to design a data transmission control method for ZigBee network terminal nodes to avoid excessive packet loss during data transmission has become an urgent problem to be solved at this stage. Contents of the invention [0004] The purpose of the present invention is to provide a data transmission control method, a communication system and a machine-readable storage medium. The data transmission control method can avoid the problem of excessive packet loss rate during data transmission, avoi...
