Airborne Internet of Things terminal and information transmission method

Abstract

The invention discloses an airborne Internet of Things terminal and an information transmission method, and belongs to the technical field of Internet of Things. An airborne Internet of Things terminal is installed in an unmanned aerial vehicle or a general aircraft to receive data transmitted by an airborne sensor and transmit the data to a satellite radio frequency unit to realize frequency conversion, so that a synchronous or medium-low orbit communication satellite can receive a signal through a transmitting behavior of a two-dimensional phased array antenna. The beneficial effects of theinvention are that the method achieves the IOT communication of synchronous or medium-low orbit satellites through one terminal, and solves a problem that a conventional IOT is short in transmission distance and cannot achieve the information collection of cross-region coverage through the long-distance coverage of the satellites; and the satellite can be accurately and quickly aligned in the static and high-speed operation of the aircraft, and the real-time communication of information is completed.

Description

Technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an airborne Internet of Things terminal and an information transmission method. Background technique [0002] The existing Internet of Things is mainly based on operators' ground public mobile communication networks or self-built gateways to build short-distance closed Internet of Things. The Internet of Things terminals use VHF\UHF and other lower 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, in areas where the operator's ground network cannot cover or cannot be deployed with access gateways, 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 refrigerators based on Beido...

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 and vigorous Internet of Things application development needs, and The patent does not involve specific IoT terminal design and structure, etc.
