Abstract

The utility model relates to an intelligent urban transport system based on a low-altitude unmanned aerial vehicle (UAV) platform. It finds application in improving the management of urban traffic, which due to the sharp increase in urbanization is merely reaching its limits. For countries such as Bulgaria, it is appropriate to create a single integrated system, which is managed centrally, but also allows decentralized use by the relevant stakeholders. What is more, the platform can assist in route planning, monitoring of intersections, determination and analysis of traffic parameters, detection and analysis of traffic accidents, etc. According to Fig. the intelligent urban transport system based on a low-altitude unmanned aerial vehicle platform comprises a ground-based urban mobility center (1), a transceiver unit (2) and air-based local drones (3I, 3II, 3III, 3IV) and a drone repeater (4), as the latter is at a higher altitude. There is a cable connection between the ground units (1 and 2). Depending on the area of the monitored urban area, the transceiver units can be two or more, and the local drones - four or more. The drone repeater (4) and the local drones (3I, 3II, 3III, 3IV) are connected to each other by a wireless radio telemetry connection, as the latter are connected in the same way to the urban mobility center (1) and to the transceiver unit (2), and each local drone (3) has radio telemetry communication with the neighbouring one.

Description

Field of technology

The utility model refers to an intelligent urban transport system based on a platform of low-flying unmanned aerial vehicles (UAVs). The application is in improving the management of urban traffic, which due to the sharp increase in urbanization is increasingly reaching the limits of its capacity. For countries like Bulgaria, it is appropriate to create a single integrated system, which is managed centrally, but also allows decentralized use by relevant stakeholders.

BACKGROUND OF THE INVENTION

Positioned assistance systems for traffic on highways are known, which provide safe and comfortable traffic on them. In some cases, they are used only in individual sections, and often without an air segment. Most of them are based on manned helicopters.

A disadvantage of the known systems is the relatively higher cost of the flight, the limited duration of the flight imposed by the presence of a person on board, the flight altitude restrictions, etc.

Technical essence of the utility model

The task of the utility model is to create an intelligent urban transport system based on a low-flying platform of unmanned aerial vehicles. The system will be able to realize long-term and comprehensive access to information on urban traffic and allow intelligent intervention in it.

According to the utility model, the task was solved by creating an intelligent urban transport system based on a low-flying platform of unmanned aerial vehicles.

The proposed system is based on a low-flying platform of unmanned aerial vehicles (local drones), at a higher altitude above which a drone repeater flies. UAVs "monitor" the urban area and can transmit the information to an urban mobility center. In the absence of visibility between the center and one of the local drones, the information is transmitted to the high-flying repeater drone or to a neighboring local drone, which in turn retransmits it to the center. The system also includes a transceiver center, which can also receive information from local drones and transmit it via cable to the urban mobility center.

Advantages of the utility model

The advantages of the utility model are that the intelligent urban transport system based on a low-flying platform of unmanned aerial vehicles has a significantly lower cost, eliminating the restrictions on altitude.

In connection with the rapid development of unmanned vehicles, urban traffic management will face new problems and challenges. Such an intelligent system will show its advantages even more clearly and will play an even greater role in the management of urban traffic. In addition, the platform can assist in route planning, monitoring of intersections, determination and analysis of traffic parameters, detection of traffic accidents, etc.

An exemplary embodiment is shown in the attached Figure 1, which is a block diagram of an intelligent urban transport system based on a low-flying platform of unmanned aerial vehicles.

Example of implementation of the utility model

According to FIG. 1, the intelligent urban transport system based on a low-flying platform unmanned aerial vehicles consists of ground-based urban mobility center 1, transceiver unit 2 and air-based local drones H ¹ , 3 ⁿ , 3 ^w , 3 ^IV and drone repeater 4. There is a cable connection between ground units 1 and 2. Depending on the area of

The drone repeater 4 is at a higher altitude, at which it and the local drones З ¹ , З ^п , З ^ш , 3 ^IV are connected to each other by a wireless radiotelemetric connection, the latter being connected in the same way to the center for urban mobility 1. and with the transceiver unit 2, and each local drone 3 is in radiotelemetric communication with its neighbor.

Action of the utility model

The intelligent urban transport system based on a low-flying unmanned aerial vehicle platform works as follows.

The local drones 3 monitor their respective territories and send the information to the urban mobility center 1. Those of them, which have no connection with the latter, send the information to the higher flying and respectively with a larger radio range drone repeater 4, which in turn sends it to the center 1. There the information is processed and the relevant management decisions are made. It is possible for each local drone 3 to forward the information to its neighbor as well as to the transceiver unit 2, which in turn forwards it to the center via the cable connection.
