Wide-area low-power-consumption Internet-of-things communication system and transmission method thereof

Abstract

The invention discloses a wide-area low-power-consumption Internet-of-things communication system, and belongs to the technical field of Internet-of-things. The wide-area low-power-consumption Internet-of-things communication system comprises a plurality of Internet-of-things terminals. Data are received and preprocessed through the Internet-of-things terminal module. The signals are transmitted to the satellite radio frequency unit to realize frequency conversion; the synchronous orbit communication satellite receives the signal through the emission behavior of the two-dimensional phased array antenna, receives the information and forwards the information to the satellite Interent-of-things gateway station, the satellite Internet-of-things gateway station receives the information and transmits the information to the cloud computing center, and the cloud computing center processes the information and uploads the information to the client Internet-of-things application platform; the beneficial effects of the invention are that the system enables various types of IOT terminals to form a wide-area IOT network through employing the synchronous orbit satellite and the gateway station, and achieves the wide-area IOT communication; the low-power-consumption design is adopted, the terminal satellite radio frequency unit is automatically awakened and closed by monitoring data, and the working time of the terminal is prolonged.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a wide-area low-power Internet of Things communication system and a transmission method thereof. Background technique [0002] The existing Internet of Things is mainly based on the short-distance closed Internet of Things network built by the operator's ground public mobile communication network or self-built gateway. The Internet of Things terminal uses VHF\UHF and other low frequencies of several hundred MHz to achieve short-distance wireless communication. ; It must rely on the operator's ground network or access gateway. In remote areas, oceans, air and other areas, where the operator's ground network cannot cover or the access gateway cannot be deployed, it will not be able to provide communication connections for the Internet of Things. [0003] The Chinese patent with the application number 201410845811.1 proposes a method of a dedicated IoT gateway for ref...

Problems solved by technology

[0004] The Chinese patent with the application number 201711416665.0 proposes a system based on the Internet of Things constellation composed of multiple Internet of Things small satellites to realize the data collection and transmission of the Internet of Things. There are many low-orbit small satellites, and dozens or even thousands of them are needed to achieve real-time large-scale ground coverage, and it takes several years from implementation to operation to provide services, which cannot meet the current rapid development needs of Internet of Things applications.
