Description

The invention relates to traffic control systems and is intended for photo and video recording, incl. automatic photo and video recording of the flow and administrative offenses committed by road users - vehicles.

A known system for automatic recording of violations of the rules of parking and parking of vehicles [1], including a hardware-software video monitoring system, made with the possibility of digital video recording of parking and parking places, pre-processing of digital video recording and transmission of the results of this processing to a remote data processing server, and containing a data processing computer connected to a video camera, the image from which is supplied to it in digital form in real time, as well as to a navigation module configured to determine the current coordinates of the patrol vehicle; the video control hardware-software complex is connected via a wireless communication channel to a remote data processing center for making decisions on violations.

The disadvantage of this utility model is that its use is effective only when installed on a patrol vehicle, which does not provide the ability to detect violations in areas where vehicle access is limited, or fix vehicles with an unreadable or hidden state registration plate. In addition, the system is aimed solely at fixing violations of parking and parking rules, which limits the scope of the utility model, and the automatic qualification of offenses can cause the formation of erroneous decisions, due to the impossibility of manually changing the restriction mode on the patrolled area, which can affect the qualification.

A device is known for fixing violations of the high-speed mode of movement of motor vehicles [2], containing two computer units installed at the boundaries of a road section of a given length, equipped with video cameras designed to transmit data to computer units for recognizing license plates, as well as a communication channel between the first and second computer blocks.

The specified device implements the speed measurement function on one of the two computers in a pair, which increases costs and requires the installation of additional recorders when arranging several successive average speed control sections along a long route.

A device for fixing violations of the high-speed mode of road transport [3], containing at least two registrars, each of which includes at least one computer and a video camera and is configured to capture an image of the vehicle, each registrar is equipped with a global satellite receiver navigation system for communication with the global satellite navigation system and is configured to determine its geographic coordinates and time synchronization, moreover, the computer is additionally connected through a firewall with a cryptographic provider to an adapter and a modem, which is connected through the operator’s communication system via a data network to a computer center made with the possibility of calculating the speed of the vehicle according to the data received from at least two registrars, and the cryptographic provider is installed with the possibility of protecting the processed data by the registrar with an electronic digital signature.

This device is positioned as mobile, so the distance between two adjacent control lines is determined for each fact of measurement by the value of the current coordinates, which does not allow using this device on road sections with turns and elevation changes.

A common disadvantage of the above analogues is their narrow functional specialization, which is designed only for calculating the average speed of vehicles and does not provide other information about the parameters of the traffic flow and individual vehicles.

A multi-purpose system for fixing violations involving vehicles [4] is known, including at least one portable individual photofixation device equipped with a navigation module, a control and visualization unit in the form of a touch LCD screen, a data storage unit, an autonomous power supply and a wireless communication module, and configured to wirelessly transmit data to a remote server, characterized in that the portable individual device contains at least one camera, while the system includes an information processing unit that includes a module configured to recognize a violation of the state registration mark recorded on the spot and identifying the violator's vehicle, a module configured to determine the type of traffic violation based on information about restrictions in a given area, and a module configured to determine address of the location of the recorded violation according to navigation data and data obtained during the analysis of overview frames.

The specified analog is capable of fixing only stationary vehicles, which reduces the range of offenses for fixing which it can be used. The disadvantage of the system is also the inability to manually adjust the restrictions on the patrolled area when the traffic situation changes (repair work, transfer of markings, installation of new signs, etc.). In addition, the outer shell of the system device does not have the necessary level of security that provides the device with the ability to withstand damage and adverse environmental conditions, and the user's free access to the battery compartment to replace the battery can reduce its service life and compromise the integrity and security of the device.

Closest to the proposed system is an automated traffic flow monitoring system with the function of determining the average speed of the vehicle in the area [5], including at least two registrars, each of which includes at least one video camera and a computer connected by a communication channel to a remote server, different by the fact that the remote server contains a block for calculating the average speed of a vehicle in a section based on data received from two neighboring registrars, a block for synchronizing time between registrars, a block for comparing recognized license plates with an external database in order to identify and control the movement of transport objects of interest, a block information storage.

The disadvantage of this system is the low reliability of the proposed system of automated traffic flow monitoring and narrow functionality.

The objective of the invention is to improve reliability and expand functionality.

The task is achieved by the fact that in the centralized system of photo-video recording (FVF) of offenses and the flow of vehicles, including one or more registrars at each turn, as well as a remote server containing a computer, according to the invention, the remote server is made in the form of a transit data processing center, each registrar includes one or more recognizing video cameras, one or more IR projectors and one or more surveillance cameras, the system additionally includes switching equipment, the input of each of which is connected to the recorder, and the output to the switching cabinet connected via Ethernet to a computer connected to a central archive server and a data center storage system, while the switching heating cabinet is also connected via Ethernet to the video surveillance system server. Each recorder additionally includes one or more radars.

The achieved technical result is:

- optimal use of server capacities. Video streams from different borders can be processed on one calculator server. In the case of large intersections, several servers can be used to process one intersection.

- use of unified server hardware.

- maximum service life, since the server equipment is located in an air-conditioned room.

- management of the entire system in single window mode.

In addition, VERelay allows you to control the operation of various devices connected via the RS-232/485 interface. Power management consists in turning it on/off depending on the status of external devices controlled via the local Ethernet network. VERelay also turns on/off the temperature stabilization devices depending on the readings of the temperature sensors. VERelay is configured via a local network from a computer with a Web browser installed.

A data transmission network that provides connectivity to existing frontiers with computers at a centralized site. Ethernet L2/L3 network with TCP/IP protocol support is provided by the telecom operator. Network bandwidth requirements are 1 Gbps for each 2 Netcam video camera and border, followed by aggregation on the operator's network and transmission of information with a total bandwidth of 40 Gbps to a centralized site. At the site, the reverse process of dividing the streams of Netcam cameras into 1 Gbit interfaces and connecting to separate ports of computers for further processing takes place.

Calculator 9 is a centralized hardware and software complex. It consists of 23 servers with up to 4 Netcam recognizing cameras connected to each server. Server operating system Windows server and software are installed on the servers. The main function of the calculator 9 is the conversion of the video stream into photographic material, recognition of state registration marks on the photographic material and transfer to the central archive.

The Central Archive is a hardware and software complex. Consists of one server. The server operating system Windows server and software are installed on the central archive server 10. The main function of the central archive is to receive data from the calculator 9 and on the basis of the data received, the definition of an offense with the subsequent transfer of the material of the offense to the storage point.

The video surveillance system consists of one server. The server operating system Windows server and software are installed on the video surveillance system server 11. The main function of the video surveillance system is to receive a video stream from surveillance cameras, store a certain period of time and provide video fragments of violations at the request of the central archive.

The proposed centralized system of photo-video recording (FVF) of offenses works as follows. From the complex of each control line 1 FVF, information about the passing transport in the form of two video streams is sent via the data transmission network of the telecom operator to the transit data center 8 to the equipment of the centralized system of the FVF. The stream from the recognizing video cameras 2 Netcam goes to the servers of the calculator 9. The stream from the surveillance cameras 6 goes to the server of the video surveillance system 11. On the calculator 9 the video stream is converted into photographic material by software. The photographic material within each server of the calculator 9 is divided into two parts. The flow of vehicles and the material of the offense. The flow of vehicles is transferred from the calculator 9 to the data center storage system. The material of offenses is transferred to the database of the central archive server. Thus, it does not matter where the border of the FVF is geographically located: the processing of the border data is carried out in the transit data center 8.

The video surveillance system server 11 records the received video stream at its own capacities and transfers it further to the storage system of the data center 12. The stream stored at the request of the central archive is provided in the form of small video clips to confirm the fact of the offense.

In the central archive, the data received from the servers of the calculator 9 are recorded in the database. On the basis of data on offenses previously generated by the calculator 9, the central archive conducts its own analysis of offenses. Having data from several calculator servers, the central archive can recognize more complex offenses. When identifying offenses, the central archive forms an evidence base for issuing a decision by the Center for Automatic Recording of Administrative Offenses in the field of traffic. The evidence base includes photographic materials and a video clip received upon request from the video surveillance system. Then the central archive sends materials on the offense to the data center storage system.

Management and monitoring of the entire system is carried out from the automatic workplace of the FVF using specialized software.
