Vehicle-mounted Internet of Things terminal and information transmission method thereof

Abstract

The invention discloses a vehicle-mounted Internet of Things terminal and an information transmission method, and belongs to the technical field of Internet of Things. The vehicle-mounted Internet ofThings terminal is fixed on a vehicle and moves to a designated place or performs mobile patrol along with the vehicle; the vehicle-mounted Internet of Things terminal receives data transmitted by thesensor and transmits the data to the satellite radio frequency unit for frequency conversion, the two-dimensional phased array antenna sends the information after frequency conversion to the synchronous or medium-low orbit communication satellite, and the synchronous or medium-low orbit communication satellite sends the information to the ground information processing station. the beneficial effects of the invention 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 alignedin the stationary and running process of the vehicle, and 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 a vehicle-mounted Internet of Things terminal and an information 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 refrig...

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.
