Abstract

A satellite Internet of Things data transmission method and device based on round-robin scheduling, the method includes: grouping satellite Internet of things terminals, and presetting different round-robin scheduling periods for each group; Initiate scheduling to satellite IoT terminal devices; in response to scheduling, use classification-based storage and forwarding for data return: for non-real-time data, store first, and when the storage limit is reached, in response to scheduling, open the transmission channel for data return. For real-time data, in response to scheduling, the transmission channel is directly opened for data return; for the situation that does not belong to real-time data, when the non-real-time data is not stored and reaches the limit, the transmission channel of the satellite IoT terminal is in a periodic self-transmission In the sleep state, the transceiver channels are all closed. It greatly reduces the power consumption of general satellite IoT terminals, prolongs the service life of the terminals, and improves the environmental adaptability of deployment.

Description

technical field [0001] The present invention relates to satellite communication technology, in particular to a method and device for satellite Internet of Things data transmission based on polling scheduling. Background technique [0002] The Internet of Things technology is gradually maturing, but the practical application of the Internet of Things depends on the deployment of a large number of Internet of Things terminals. The Internet of Things terminals in some industries need to be deployed in remote areas in the wild. Such areas often do not have effective mobile or fixed network coverage. Satellite communication It has the characteristics of wide coverage and is the preferred solution for deploying ubiquitous IoT terminals. The field deployment of IoT terminals requires that the equipment can work unattended for a long time. The operation and network time of the equipment are generally measured by batteries. Therefore, the lower the power consumption requirements of t...
