Embodiment Construction

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

[0030] The present invention provides a data transmission control method of a ZigBee network terminal node. The ZigBee network data transmission control method includes:

[0031] Step 1, calculate the data transmission time of 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 and sequentially judging whether the transmission time interval between each subsequent terminal node and all terminal n...

Abstract

The invention discloses a data transmission control method, a communication system and a machine-readable storage medium, comprising: step 1, calculating the data sending time of k terminal nodes of the ZigBee network by the following formula, wherein T is a preset time Set the 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; step 2, starting from the second terminal node, judge whether the sending time interval between each subsequent terminal node and all the previous terminal nodes is greater than or equal to preset time; in the case that the sending time interval between each subsequent terminal node and all the terminal nodes in the pre-order is greater than the first preset time, control the terminal node to perform sending at the original sending time; step 3, repeat step 2 to obtain Send time for all end nodes. The invention can avoid the problem that the packet loss rate is too high during data transmission, and avoid the packet loss rate while avoiding congestion.
