Internet-of-Things data acquisition terminal energy-saving method based on satellite orbit prediction algorithm

Abstract

The invention provides an Internet-of-Things data acquisition terminal energy-saving method based on a satellite orbit prediction algorithm. The method comprises the following steps: 1,starting an Internet-of-Things data acquisition terminal based on a satellite orbit prediction algorithm to enter a normal working state and enter a data acquisition mode, 2, after a data acquisition module of the Internet-of-Things data acquisition terminal based on the satellite orbit prediction algorithm acquires and stores the environment monitoring information through a sensor, closing a data acquisition mode, and entering an orbit prediction calculation mode; 3, judging whether the satellite enters the scene or not at the current time according to the orbit prediction result in the step 2, and if the Internet-of-Things data acquisition terminal enters the entry, the Internet-of-Things data acquisition terminal enters a data transceiving mode, communicates with the satellite, finishes sending or exits, all modules are closed, and the Internet-of-Things data acquisition terminal enters a standby low-power-consumption mode, so that the communication power consumption can be remarkably reduced, andthe communication success rate of the Internet-of-Things data acquisition terminal and the satellite can be improved.

Description

technical field [0001] The invention belongs to the field of communications, and in particular relates to an energy-saving method for an Internet of Things data collection terminal based on a satellite orbit prediction algorithm. Background technique [0002] According to the definition of the International Telecommunication Union, the Internet of Things is a network that solves the interconnection between items and items, people and items, and people. The space-based Internet of Things is based on the space-based communication network, and integrates space-based navigation, remote sensing and other services to provide a comprehensive information system for barrier-free interaction between objects and objects, people and objects, and people and people. [0003] In view of the characteristics of the space-based information system, the space-based Internet of Things has added many unique advantages compared with the traditional Internet of Things: [0004] (1) The communicati...
