Description

The present invention relates to the field of transport communication, and in particular to the field of ensuring communication between moving vehicles (cars, trains, ships, etc.) along their routes both between themselves and with various consumers outside the vehicles (systems traffic control, vehicle condition monitoring services, etc.).

Known patent "Dedicated short range communication system and network architecture for intelligent transportation Systems" (EP No. WO 9922353, IPC: G08G 1/09, G08G 1/0967, (IPC1-7): G08G 1/09; priority date: 1997- 10-29). It describes the elements of an intelligent transport system and how to communicate between them. Intelligent transport system consists of a control center, road infrastructure system, vehicle system and additional broadcasting systems, interconnected by DSRC (dedicated short range communication - specialized short-range communication) and wired communication.

The control center of this intelligent transport system is an external communication network that interacts via wired communication with a variety of road transceivers forming a road infrastructure system. In turn, road transceivers via DSRC communication interact with on-board transceivers installed on vehicles, forming a system of vehicles. Thus, in an intelligent transport system, data is exchanged between an external communication network and on-board transceiver devices via road transceiver devices operating in the mode of information isolation from each other.

Additional broadcasting systems of the intelligent transport system are various warning services (such as guides, weather forecasts and others) that transmit information directly to airborne transceivers, road transceivers and an external communication network.

However, the analogue has a significant drawback, namely, the complexity of communication links due to the fact that road transceiver devices operate informationally isolated from each other and interact only with onboard transceiver devices and an external communication network. This circumstance leads to an increase in data transfer time in the intelligent transport system.

The communication element of the intellectual transport system created by the Kapsch Group is known (see the catalog of the Kapsch Group company - Electronic resource. Access mode to the resource https://www.kapsch.net/ktc/its-solutions/V2X-Cooperative- Systems - free). This communication element contains at least two road transceivers located at a distance from each other along the same route of the vehicle and connected to an external communication network via wired communication, carried out, for example, through a cable laid through the cable duct to server hardware.

The communication element of the intelligent transport system may include an additional road transceiver, which is located on an adjacent route and is made similar to the devices described above.

Each road transmitting and receiving device consists of an electronic signal receiving, transmitting and processing unit, to which a power supply interface, a setup interface, a wired communication interface with an external communication network and at least one wireless communication interface with on-board transceiver devices are connected funds. Moreover, such devices operate in information isolation mode from each other, exchanging data with airborne transceiver devices via wireless communication and with an external communication network via wired communication.

The well-known communication element of the intelligent transport system is selected as a prototype, as it has the largest number of essential features that match the essential features of the claimed invention.

However, the prototype has significant disadvantages, namely:

- the complexity of the infrastructure, due to the need for the presence along the entire route of vehicles of equipment of an external communication network, which significantly limits the area of use of the road transceiver;

- the complexity of the architecture, due to the need to connect to the external communication network of all road transceivers included in the communication element of the intelligent transport system, thereby increasing the complexity of installation and operation;

- the complexity of communication links, due to the fact that road transmitting and receiving devices operate in the mode of information isolation from each other, which leads to an increase in the transmission time of data between them.

The present invention is the creation of a new communication element of the intelligent transport system, the technical result of which is to simplify the infrastructure, architecture and communication links of the transport communication system with the simultaneous choice of the mode of operation of road transceivers.

The problem is solved due to the fact that:

- at least one wireless high-speed communication interface with similar road transceivers with the formation of an end-to-end communication channel between them is introduced into each road transceiver device;

- the communication interface with the external communication network is made by a wired connection;

- a communication interface with an external communication network is made by a wired connection, and a communication interface with an external communication network made by a wireless connection is introduced;

- the communication interface with the external communication network is made wireless;

- the communication interface with the external communication network is made by a wireless connection, and a communication interface with an external communication network made by a wired connection is introduced.

The essence of the claimed technical solution lies in the fact that in the known communication element of the intellectual transport system, containing at least two road transceiver devices located at a distance from each other along the same route, and one additional road transceiver located on adjacent route, with each road transceiver contains an electronic unit for receiving, transmitting and processing signals, to which are connected The power supply interface, the communication interface with an external communication network, and at least one wireless communication interface with vehicle on-board transceivers according to the present invention, at least one high-speed wireless communication interface is introduced into each road transceiver with similar road transceivers with the formation of an end-to-end communication channel between them.

A development option for the main technical solution is possible, consisting in the fact that the communication interface with the external communication network is wired.

A development option of the main technical solution is possible, consisting in the fact that the communication interface with the external communication network is made by wireless connection and the communication interface with the external communication network is made by wired connection.

The formation of wireless high-speed communication reduces the complexity of installing and operating the communication element of the intelligent transport system and the ability to connect one or more road transceivers from their total number.

The applicant has conducted a patent search on this topic, as a result of which the claimed combination of essential features has not been identified. Therefore, the present invention can be considered new.

The claimed technical solution meets the criterion of patentability "inventive step", as it logically does not follow from the prior art. Well-known technical solutions describe the communication elements of the intelligent transport system that are more difficult to connect and operate. As an example, the patent “Dedicated short range communication system and network architecture for intelligent transportation systems” (EP No. WO 9922353, IPC: G08G 1/09, G08G 1/0967, (IPC 1-7): G08G 1/09; date priority: 1997-10-29) and a prototype in which the road receiving and transmitting devices of the communication element of the intelligent transport system operate in the information isolation mode from each other, exchanging data only with the on-board receiving and transmitting devices and with the external communication network, while each road transceiver is a must widely regarded as one connected to an external communication network.

In the claimed invention, when forming a communication element of an intelligent transport system, it is possible to connect to an external communication network through one road transceiver connected via a communication channel with similar road transceivers through a communication interface with an external communication network. In this case, the communication interface with the external communication network can be made by wireless or wired connection with the possibility of duplicating the connection by means of the additionally introduced interface of wired or wireless connection, respectively. This provides the simplification of communication links, architecture and infrastructure of the communication element of the intelligent transport system.

At the same time, an end-to-end communication channel 13 is formed between road transceivers 2, 5 via wireless high-speed communication interfaces 10 along vehicle routes 3, 6, and to an external communication network 12 using a wired and / or wireless high-speed interface 11 only one road transceiver is connected 2. For connecting to an external communication network 12 instead of an interface 11 of a wired and / or wireless high-speed communication, or in addition to it, A wireless high-speed interface 10 with similar transceivers can be used.
