Airborne IoT terminal and information transmission method

Abstract

The invention discloses an airborne Internet of Things terminal and an information transmission method, which belong to the technical field of the Internet of Things; by installing the airborne Internet of Things terminal in an unmanned aerial vehicle or a general-purpose aircraft, the data transmitted by the on-board sensor is received and transmitted to The satellite radio frequency unit realizes frequency conversion, so that the synchronous or medium-low orbit communication satellite can receive signals through the transmission behavior of the two-dimensional phased array antenna; Networked communication, through the long-distance coverage of satellites, solves the problem of the short transmission distance of the traditional Internet of Things and the inability to achieve cross-regional coverage of information collection; and realizes accurate and fast alignment of satellites when the aircraft is stationary and at high speed, and completes Real-time communication of information.

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 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 refrigerators based ...

[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.
