Description

The utility model relates to systems of automated control over the movement of vehicles (TS) and detection and fixing of violations of traffic rules by a vehicle, including for fixing vehicles that exceed speed.

In Russia and in the world there are a large number of number recognition systems. In particular, these are the companies “Recognition Technologies” SPB, “Elviis” Zelenograd, “VIT” Kiev, CTV Moscow. They develop recognition SDKs and provide them to third-party recognition device developers. One of the well-known devices based on such an SDK is “KRIS” Spb.

A known system for monitoring the movement of vehicles (RF patent No. 75768, IPC G08G 1/00, publ. 08/20/2008), comprising at least one group of pressure sensitive detection sensors installed in the roadway, connected to a speed calculation and registration device the movement of vehicles, a transceiver connected to a device for calculating and recording the speed of vehicles.

A device for determining the speed and coordinates of vehicles with their subsequent identification and automatic registration of violations of traffic rules (RF patent No. 2382416, IPC G08G 1/052, G08G 1/017, G07C 5/08, publ. 02.20.2010), containing a radar, at least one state registration mark recognition video camera, and a control and data processing unit connected to them, the radar contains a signal processing module that calculates the speed and range of all vehicles located on the selected section of roadway.

A device is known for fixing violations of the high-speed mode of movement of automobile transport (RF patent No. 101243, IPC G08G 1/052, published January 10, 2011), which is closest to the claimed solution and adopted as a prototype containing two computer units mounted on the boundaries of a given length of road section equipped with video cameras designed to transmit data to computer units for recognition of license plates, as well as a communication channel between the first and second computer units.

However, the known devices require a high-speed uninterrupted data transmission channel from registrars (cameras) to a central point, require high costs for the construction of high-speed communication lines, make it practically impossible to measure vehicle speed over long distances due to the high cost of communication channels, and do not allow you to quickly transfer the observation point for by transport.

To eliminate these shortcomings, the claimed system has the following distinctive features:

- each recorder is equipped with a global satellite navigation system receiver;

- in each registrar, a calculator and software with a cryptographic provider are installed, which provides the ability to protect the processed data with an electronic digital signature (EDS);

- in each registrar, a synchronization system is installed, in which the synchronization of the registrars will be ensured in them themselves due to an external global source of synchronization - one (or a combination of several) global navigation satellite systems (GLONASS, GPS, Galileo, etc.).

To ensure that the data is received from the registrars included in the system (and not from someone else’s, false or faulty device), each vehicle fixation, together with the registrar’s coordinate on the earth’s surface, is currently signed with an electronic digital signature. The system acquires unique mobility, since each registrar can easily move from one point to another. Registrars can work even in motion, being installed on moving vehicles (with a slight increase in measurement error). Registrars can be spaced at any arbitrarily large distance and do not require the cost of building high-speed communication lines. Registrars can work autonomously, accumulating data for several weeks and provide data for the final calculation at any convenient time. Thanks to the smart algorithm used, it is possible to use even wireless low-speed channels, such as GPRS.

The objectives of the utility model are:

- unique mobility of the system up to the ability to measure vehicle speed when moving recorders (through the use of GLONASS);

- synchronization of system elements by using technologies of the global navigation satellite system;

- the possibility of unlimited battery life without maintenance;

- work on low-speed communication lines;

- low price of the system in comparison with other systems for photofixation of violations of the high-speed mode due to the simplicity of the system;

- giving legal significance to the transmitted data through the use of electronic digital signature;

- high accuracy of positioning and synchronization (up to 1 μs) through the use of a global navigation system;

- the impossibility of distorting the results due to falsification of data;

- high level of information security.

- optimization of data transmission about fixed vehicles from registrars to a computer center;

- optimization of the load of the data transmission channel;

- reduction in the amount of information transmitted;

- improving the reliability of data transmission;

- reducing the cost of installing registrars, due to the fact that they can be fixed on lampposts or poles of power lines and do not require the use of transverse trusses above the road.

The technical result, which the proposed utility model is aimed at, is to increase the efficiency of detecting and fixing violations of traffic rules, and to increase information security.

Communication with a computer center 9 is carried out via a data network 8 through a GSM operator’s communication system 7 connection to which is carried out using the GPRS \ 3G modem 5.

Computer 1 is connected to external devices: a video camera 2 with IR illumination via FastEthemet interface, global satellite navigation system 10 through a GLONASS / GPS 3 receiver via RS-232 interface.

Computer 1 is also connected via a firewall with a cryptographic provider 6 with an adapter 4 via a USB 2.0 interface and with a modem 5 via a USB 2.0 interface, which is connected to a data center 9 through an operator’s communication system 7 and data transmission network 8.

Computer 1 serves to receive and process information from a video camera 2, GLONASS / GPS receiver 3, protect data using a firewall with a cryptographic provider 6, prepare and send data about vehicle fixing facts to computer center 9 using wireless devices: adapter 4 and modem 5.

Computer 1 has an autonomous power supply system from the battery, is equipped with a hardware reboot system in the event of a freeze, a power supply with a wide input voltage range.

The computer connects to a standard 220 V electrical network or to an electric street lighting network. In the latter case, the device is powered by a battery, which is charged when the street lighting is turned on.

Linux 1 is installed on computer 1, software for creating a virtual private network, a firewall with cryptographic provider 6 to protect against changes in the data transmitted to the computer center 9. Also on the computer 1 is installed application software for the operation of the components of the system.

The communication system of the operator 7 is used to provide access to the data network 8.

The data transfer network 8 is used to transmit data on the facts of fixation of vehicles from the computer 1 to the computer center 9.

Computing center 9 serves to collect and process data on the facts of fixing vehicles from a network of registrars, in particular, based on data from two registrars located along the road, the system calculates the speed of a particular vehicle on the road section between these registrars.

The global satellite navigation system 10 is used to transmit accurate time signals and calculate the location of the recorder by the GLONASS / GPS 3 receiver.

The vehicle is the object of control, each fact of the vehicle passing by the registrar is recorded, and information about it is sent to the computer center 9 for further processing.

The system works as follows.

After applying power to the recorder, computer 1 synchronizes the time and determines the location of the recorder using the GLONASS / GPS receiver 3 and the global satellite navigation system 10. Then this procedure is performed periodically depending on the settings of the system.

Computer 1 starts collecting information. Computer 1 receives from Camera 2 via FastEthernet interface photographs of vehicles passing by it, on which state registration marks (GRZ) of vehicles are recognized using special software. As soon as a GRD is detected in the photo, computer 1 compares the photo with the exact time and exact coordinates, signs this data using a firewall with the cryptographic provider 6 and saves them and the block of confirming information received using the cryptographic provider in the local database of computer 1. If the GRD in the photograph does not recognized, the photo is permanently deleted.

The exchange of data between computer 1 and computing center 9 is carried out through a data network 8. Computer 1 is connected to this network through a communication system of an operator 7 via a modem 5.

Further, at a certain point in time, depending on the settings of the system, computer 1, through a modem 5, establishes a connection with the computer center 9 through the data transfer network 8 and transmits to the computer center 9 the accumulated information about the facts of the vehicle’s fixation, consisting of recognized GRZ, geographical coordinates fixation time. The photograph remains in the registrar database.

Computing center 9 receives data from several registrars installed along the road and compares them with each other. Having information about the distance between the registrars (at the exact coordinates of the registrar), the permitted speed in this section, as well as the time difference between the moments of registration of the same vehicle, the computer center 9 calculates the average speed of the vehicle in this section. Computing center 9 compares the calculated vehicle speed with the allowed speed on a given section of the road and makes a decision on the presence of a speed violation.

If the violation is not fixed, the computing center 9 executes on the computer 1 of all registrars a command to delete data on the fact of fixation for the data from which the vehicle speed was calculated.

In case of exceeding the permissible speed, the computer center 9 downloads from all the registrars, according to which the vehicle speed was calculated, photos of the vehicle and a block of confirming information.

The computing center 9 uses a block of confirming information to confirm the integrity of the data, on the basis of which the fact of exceeding the permissible speed is established. If the confirmation of the information was successful, then the computer center 9 generates an administrative offense protocol, supplemented by photographs of the vehicle obtained from both registrars involved in determining the speed of the vehicle. Otherwise, the data is rejected, and a protocol is not generated. After that, regardless of the results of the verification, the computer center 9 deletes data from the registrar about the fact of fixing the vehicle.

If the data network 8 does not have sufficient bandwidth, photographs of the intruder’s vehicle are accumulated in the database of computer 1 for subsequent transmission via adapter 4 to the data storage unit on the dispatching machine.

The disk size of computer 1 allows you to store photos for more than 30 days.

Limitations for using the system:

- the minimum distance between the registrars should be at least 500 m (with an allowable error in determining the speed of 5%). With a decrease in the distance between the registrars, the error in determining the speed of vehicles (TS) increases exponentially (Fig. 2).

- the maximum distance between the registrars is limited only by the characteristics of the road where the registrars are installed:

- on the road section where the recorders are installed (control zone) there should be a single speed mode, i.e. the presence of sections within the control zone with various restrictions on the vehicle speed is unacceptable.

- inside the control zone, it is not advisable to have exits from the road. It is recommended that before exiting the road, end one control zone and begin the next one after it. In general, the decision to complete the control zone before the exit from the road should be made based on the size of the flow of vehicles towards the exit. With insignificant flows of vehicles, the control zone can not be interrupted.

- the distance traveled is calculated on the basis of the assumption of the rectilinear shape of the road, therefore, the closer the section of the road to the straight line, the more accurately the vehicle speed will be determined. It is worth noting that the presence of deviations in the shape of the road from a straight line leads to the fact that the measured speed will be lower than real, i.e. the error will go solely in favor of the driver. This restriction can be removed by calculating the distance traveled with reference to road maps. The claimed system has the following advantages:

- allows you to quickly transfer registrars from place to place;

- allows you to measure the speed of vehicles even when installing recorders on a moving vehicle;

- allows you to abandon high-speed communication channels;

- allows you to conduct long-term work in offline mode;

- allows you to significantly reduce the cost of the system.
