Global real-time internet of things constellation system

Abstract

The invention provides a global real-time Internet of things (IOT) constellation system. The system includes a space segment including a plurality of low-orbit satellites that are interconnected through inter-satellite links, a ground segment which is used for completing an operation control function and a data distribution and recovery processing function. The ground segment includes a pluralityof constellation gateway stations. The system also comprises a user segment which is used for collecting sensing data and comprises a plurality of user terminals. The constellation gateway stations ofthe ground segment and the user terminals of the user segment communicate with the low-orbit satellites of the space segment through respective links. The system has the advantages that the system isfor the cloud, network and end system level designs of global wide-area space-based IOT applications, and the IOT new connection and management capabilities of multiple industrial mass applications are achieved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a global real-time Internet of Things constellation system. Background technique [0002] The Internet of things (IoT) refers to the use of various information sensing devices (such as radio frequency identification, infrared sensors, global positioning systems, laser scanners, etc.) A network concept that connects, exchanges information and communicates to realize intelligent identification, positioning, tracking, monitoring and management. The Internet of Things is an important part of the new generation of information technology, and it is also an important stage of development in the "informationization" era. The Internet of Things is widely used in the integration of networks through communication perception technologies such as intelligent perception, identification technology and pervasive computing. Therefore, it is called the third wave of the...

Problems solved by technology

[0006] However, the transmission distance of traditional access methods such as Wi-Fi, ZigBee, and Bluetooth is too short, and data must be sent to the base station through the user's mobile phone, relay gateway, or AP point, which will result in low data accuracy and low power consumption. high problem

Although 2G / 3G / 4G networks can be used for the transmission of sensor data with low data volume, the cost and power consumption are relatively high
