Description

[0001] DESCRIPTION OF THE INVENTION

[0002] Internet of Very Important Things (loVIT)

[0003] The invention relates to the fields of radio engineering and software, and more specifically to Internet of Things systems (an Internet of Things object is a product with Internet access and equipped with means of interaction with the environment) and can be used in virtually any industry for the automation of technological processes, monitoring and remote control of technical systems, as well as for providing two-way low-speed communication (several kbit / s to tens of kbit / s) via standard TCP / IP protocols from remote terminals to the Internet (for example, for agricultural applications, utilities, asset tracking, etc.).

[0004] A device is known for transmitting and receiving a physical downlink / uplink channel, wherein in-band operation is supported by a radio access system that supports the narrowband Internet of Things (NB-IoT) and may include: receiving a higher-layer signal indicating the in-band deployment mode; receiving a narrowband primary synchronization signal (M-PSS) and a narrowband secondary synchronization signal (M-SSS) configured for NB-IoT systems; receiving a cell identifier (N-Cell ID) of the NB-IoT system from the M-SSS; and receiving the M-PBS using the N-Cell ID in the in-band deployment mode. In this case, the in-band deployment mode indicates that the NB-IoT system is configured in the band of the legacy LTE system / EP 3349379 Al, IPC H04J 11 / 00, H04L 5 / 00, published 18.07.2018 / .

[0005] The disadvantages of the well-known IoT system based on a terrestrial gateway network are the cost of its operation and the limited coverage of a small region, since it is provided by cellular stations (each such gateway can usually be used by terminals no further than 20-30 km from it).

[0006] A system is known that uses a satellite, a hub and a plurality of VSAT terminals. Systems based on VSAT terminals typically provide two-way communication via geostationary communication satellites, provide transmission rates of up to several Mbit / s and have a wide range of applications, in which transmissions from said hub are typically continuous, and transmissions from said VSAT terminals are typically carried out in the form of packets, wherein said method is characterized in that each of said plurality of VSAT terminals communicates with said hub in a star configuration for control functions and communicates with others of said plurality of VSAT terminals in a mesh configuration for functions not related to control / EP 1050173 A1, IPC H04B 7 / 15, H04B 7 / 185, H04L 12 / 28, published 08.11.2000 / .

[0007] The disadvantages of this well-known technical solution are the high cost of equipment and the economic infeasibility due to the high subscription fee for supporting the IoT application.

[0008] The closest in technical essence and achieved result to the claimed invention is a satellite communication terminal for IoT applications, adopted as a prototype, which is configured to operate via a constellation of non-geostationary satellites (NGSO) and comprises at least a modem, at least a fixed non-tracking antenna connected to the modem. The terminal can communicate with an NGSO satellite each time it passes through the beam of the antenna of the terminal (communication opportunity). Although the communication opportunities are short and can be repeated after relatively long intervals of time (for example, from one to tens of minutes), these communication opportunities may be sufficient for transmitting the volumes of information generated by Internet of Things (IoT) applications in the intervals between communication opportunities / CA 3167454 A1, IPC G16Y30 / 00, G16Y40 / 10, H04B7 / 185, H04B7 / 195, published 12.01.2023 / .

[0009] Despite its advantages, significant disadvantages of the known prototype include increased operational complexity, waiting for the connection to open, limited operating time, and economic infeasibility.

[0010] The objective of the invention is to eliminate the drawback and improve the solutions of the prior art, namely, to develop a highly reliable and low-power system with a compact and low-budget remote Terminal for providing low-speed continuous Internet communication between a massive network of Terminals using standard geostationary and, if necessary, non-geostationary communication satellites.

[0011] The technical result that can be achieved using the claimed invention is the coverage of a large area by using new standards for terrestrial communication between terminals such as LoRa / LPWAN and other NB-IoT satellite communication standards, compactness relative to existing terminals, reduced costs for installation, operation and maintenance, and, of course, increased security and data privacy.

[0012] The stated problem is solved and the technical result is achieved by the fact that in the Internet of Things (IoT) system, consisting of user equipment, a remote Terminal containing an antenna of the remote Terminal system, a geostationary communications satellite and, if necessary, a group of non-geostationary communications satellites, a system data processing center and a user interface on the Internet, what is new according to the invention is that the system includes a gateway station containing an antenna system of the gateway station and gateway equipment of the Internet of Things, wherein a geostationary communications satellite is additionally used as a satellite for data transmission, and the terminal with cryptographic software installed therein contains a data processing unit and a power module, wherein the data collection distance is up to 200 km, taking into account the possibility of distributing a terrestrial network based on LoRa / LPWAN access points, implemented by part of the functionality of the invention.

[0013] The claimed invention is explained by a drawing, where Figure 1 shows a functional and structural diagram of the system with the following positions: 1 - user equipment; 2 - data processing unit; 3 - antenna system of the remote Terminal; 4 - power module; remote Terminal; 6 - geostationary communications satellite; 7 - antenna system of the gateway station; 8 - IoT gateway equipment; 9 - gateway station; 10 - data processing center of the IoT system; 11 - user interface on the Internet.

[0014] The essence of the invention and the possibility of achieving the technical result are disclosed in more detail in the example below of the Geostationary Satellite Communication Terminal for the Internet of Things.

[0015] Structurally, the invention consists of terminals and a data processing center. Functionally, the system involves terminals, user equipment connected to them remotely, geostationary communications satellites, and their gateway stations. The services of the latter are required to ensure communication.

[0016] Each terminal consists of an antenna system, a data processing unit, and a power module. The antenna system includes all the necessary components for downconverting and upconverting the data signal from the intermediate frequency (IF) to the appropriate geostationary satellite frequency (RF) and back.

[0017] The digitized signal at the intermediate frequency is modulated / demodulated and encoded in digital format in the information processing unit, which is also capable of implementing Ethernet (IEEE 802.3 standard), LoRa, or any other similar interface to ensure communication between user equipment.

[0018] The data processing unit is also responsible for implementing the system's blockchain functionality, namely storing codes, public signatures, hashing, and encryption. After blockchain processing, the data is transferred to the data center, where it can undergo further processing, including analysis, aggregation, and so on.

[0019] Since the Terminal's transmission speed requirements are several orders of magnitude lower than those of standard VSAT Terminals, the RF path and antenna system characteristics for the invention are much lower, allowing the Terminals to use very compact antennas without a reflector architecture. The extensive use of software-defined radio systems reduces the cost and increases the flexibility of both the Terminals and the IoT equipment installed at gateway stations.

[0020] The very low transmitter powers of the Terminals also make their licensing and certification much easier.

[0021] Figure 1 shows a general functional and structural diagram of the invention (for simplicity, a configuration with one Terminal is shown):

[0022] - user equipment (1);

[0023] - a remote Terminal (5), consisting of data processing units (2), an antenna system (3) and a power module (4);

[0024] - geostationary communications satellite (6); - gateway station (9), consisting of an antenna system (7) and gateway equipment IoT (carrying out digital and analog processing of signals from and to the Terminals) (8);

[0025] - data processing center of the IOT system (10);

[0026] - user interfaces on the Internet (11).

[0027] The terminals combine compact size and minimal infrastructure requirements with extensive functionality and a high level of security. These two factors are enabled by blockchain technology and support for various wireless communication standards. These characteristics allow for a reduction in the cost of deploying and operating mass IoT networks by 3-25 times, while maintaining quality, compared to solutions currently available on the telecommunications market, particularly satellite communications.

[0028] When transmitting data over the internet, it is possible to encrypt data using blockchain technology or other cryptographic algorithms to ensure the verifiability of services provided by the Terminal, in particular the fact of transmission / reception. Furthermore, blockchain technology ensures the confidentiality and security of Terminal user data.

[0029] A significant difference between the claimed Internet of Things (IoT) system and the prior art is that, at a minimum, it collects data from around itself at a distance of up to 200 km; at a minimum, it has the ability to install cryptographic software or cryptographic chips, including Blockchain; and at a minimum, it transmits data via satellite channels, both through geostationary and non-geostationary communication satellites.
