Abstract

The invention discloses a data transmission method and a communication system. The communication system comprises a central node and a plurality of child nodes. The method comprises the following steps: the central node sends a wake-up signal; the child node receives a wake-up signal and enters a wake-up state. The central node sends a data signal; the child node receives the data signal and transmits the data to be transmitted at a random time in a preset time period after receiving the data signal when the child node needs to transmit the data to be transmitted. The child node transmitting the data to be transmitted judges whether the data to be transmitted is successfully transmitted; If the data to be transmitted is not successfully transmitted, the child node enters a sleep state andwaits for a wake-up signal; and if the data to be transmitted is not successfully transmitted, the child node enters a sleep state and waits for a wake-up signal. If the data transmission to be transmitted is successful, the child node enters a sleep state and no longer responds to the wake-up signal. The center node re-executes the step of transmitting the data signal at a preset time interval until the transmission of the data to be transmitted of all the child nodes is completed. This embodiment has the characteristics of high transmission efficiency and high speed.

Description

technical field [0001] The present application relates to the technical field of data transmission, and in particular, to a data transmission method and a communication system. Background technique [0002] With the rapid development of the Internet of Things technology, more and more wireless products are produced, and these wireless products often need to perform data transmission with other devices. [0003] In the prior art, these wireless products have two methods for data transmission. One of the ways is to transmit data according to the pre-network. In this transmission mode, each wireless product forms a sub-node. When there are multiple sub-nodes that need to be transmitted in the system, each sub-node needs to pass protocol for data transmission. For example, in the ZigBEE transmission system that has been completed by the self-organizing network, when the node needs to transmit data, the node is first awakened by a low-frequency wireless signal, and then transmi...
