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

Abstract

The present invention provides an energy-saving method for an Internet of Things data collection terminal based on a satellite orbit prediction algorithm, which is characterized in that: the steps are as follows: Step 1. The Internet of Things data collection terminal based on the satellite orbit prediction algorithm starts up and enters a normal working state and enters data collection Mode, step 2, after the data acquisition module of the Internet of Things data acquisition terminal based on the satellite orbit forecast algorithm collects and stores the environmental monitoring information through the sensor, close the data acquisition mode and enter the orbit forecast calculation mode; step 3, according to the orbit of step 2 The forecast result judges whether the satellite enters the country at the current time. If it enters the country, the IoT data acquisition terminal enters the data sending and receiving mode and communicates with the satellite. Significantly reduce communication power consumption, and at the same time improve the success rate of communication between IoT data acquisition terminals and satellites.

Description

Technical field [0001] The present invention belongs to the field of communications, in particular to an Internet of Things data acquisition terminal energy-saving method based on satellite orbit forecasting algorithm. Background [0002] According to the Definition of the International Telecommunication Union, the Internet of Things is a network that solves the interconnection of things and things, people and things, and people to people. Space-based Internet of Things is based on space-based communication networks as the core and foundation, and integrates space-based navigation, remote sensing and other services to provide barrier-free interaction with items and objects, people and objects, and people and people. [0003] Given the characteristics of space-based information systems, space-based IoT adds a number of unique advantages over traditional IoT: [0004] (1) The communication network covers a wide area, which can achieve global coverage, and the layout of sensors is a...

Problems solved by technology

[0006] (3) The system has strong invulnerability, and it can still work normally in emergency situations such as natural disasters and emergencies

[0020] These two schemes try to send and receive data when the communication link is uncertain, the communication success rate will be greatly reduced and will cause a large amount of additional waste of power consumption
