Description

The utility model relates to measuring equipment and is intended for automated monitoring of compliance with traffic rules, namely, to a complex of automated monitoring of violations of the high-speed mode of vehicles, with the function of determining the average speed on the site. The complex automatically identifies state registration plates (GRZ) of vehicles (TS), calculates the average vehicle speed on the site and fixes violations of the speed limit. 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.

The specified method allows you to control a section of the road with a length of not more than a few hundred meters. In addition, the radar included in its composition emits radio signals, which can be detected by special means (radar detectors) of traffic participants, which reduces the effectiveness of this system.

A device is known for recording violations of the high-speed mode of movement of automobile transport (RF patent No. 101243, IPC G08G 1/052, publ. 10.01.2011), containing two computer units mounted on the borders of a given length of the road, equipped with video cameras designed to transmit data to computer blocks for recognition of license plates, as well as a communication channel between the first and second computer blocks.

The specified device implements the function of measuring the average speed on one of the two computers in a pair, which increases costs and requires the installation of additional registrars when arranging several consecutive sections of the average speed control over a long track.

A device for fixing violations of the high-speed mode of movement of automobile transport (RF patent No. 110856, IPC G08G 1/054, published on 11/27/2011) containing at least two recorders, each of which includes at least one computer and a video camera, is made with the ability to capture the image of the vehicle, each registrar is equipped with a receiver of the global satellite navigation system for communication with the global satellite navigation system and is configured to determine its geographic x coordinates and time synchronization, in addition, the computer is connected via an firewall with a cryptographic provider to an adapter and a modem, which is connected through an operator’s communication system via a data network to a computer center that can calculate the vehicle’s speed using data received from at least two registrars, moreover, the cryptographic provider is installed with the ability to protect the processed data by the registrar with an electronic digital signature.

The specified device is positioned as mobile, therefore, the distance between two adjacent control lines is determined for each fact of measurement by the value of the current coordinates based on satellite navigation system data, which severely limits the possibility of using this device on road sections with turns and elevations. In addition, the use of global navigation system data for measuring the distance traveled by the vehicle introduces significant errors in further calculations. That is why the authors themselves indicate a minimum distance between registrars of 500 meters.

The claimed technical solution is the development of a system previously patented by the present authors (RF patent No. 135828, IPC G08G 1/052, publ. December 20, 2013) for a similar purpose.

In contrast to the indicated analogue, in the claimed technical solution, time synchronization is performed at each control line using a special satellite time synchronization device, which allows the recorders to be placed at any distance from each other, increasing the accuracy and reliability of measurements.

The technical result is the creation of a complex of automated control of violations of the high-speed mode of vehicles, characterized by an expanded geography of use, regardless of the terrain and the configuration of the road section, increased accuracy and reliability at any distance between the control lines, low operating and maintenance costs.

The claimed complex does not require the use of navigation receivers to obtain geographic coordinates, since the exact distances between the control lines are previously measured by more accurate methods, without using a satellite navigation system. Considering that the distances between stationary control lines do not change and do not depend on external factors, the claimed complex provides high accuracy and reliability of the data obtained, regardless of the length of the controlled section of the road, its configuration and terrain.

The specified technical result is achieved in that the complex of automated control of violations of the high-speed mode of vehicles contains at least two registrars, each of which is capable of photo-video recording of vehicles crossing the boundaries of the monitored area, and includes at least one video camera and computer connected by a communication channel to the server, with each recorder equipped with a satellite time synchronization device, the computer includes a hardware-software nye means providing the ability to recognize the state of license plates of vehicles, and the server comprises software means for calculating the average vehicle velocity in the area based on data obtained from two or more recorders.

The proposed technical solution uses a satellite time synchronization device, which allows you to synchronize the internal time of each recorder with global time based on signals received from GLONASS or GPS satellites. This device can operate by receiving a signal from at least one satellite. The latter guarantees the stability of the complex as a whole.

Depending on the specific operating conditions, each recorder may contain two or more video cameras, one of which can serve as a survey and perform additional functions, including the functions of strengthening the evidence base.

In some embodiments, the implementation of the computer may further comprise hardware and software tools that enable the calculation of the speed of vehicles at the corresponding border of the controlled area.

The complex may include an unlimited number of registrars and one or more servers. The number of registrars is determined by the number of road sections on which it is required to control the average vehicle speed located geographically in one area.

The essence of the utility model is illustrated in FIG. one.

In FIG. 1 shows the general structural diagram of the complex.

The claimed complex is a system of devices and units, including the following elements:

1-A and 1-B - registrars,

2 - computer,

3 - video camera,

4 - device satellite time synchronization,

5 - remote server.

Registrars 1-A and 1-B are sets of devices consisting of a video camera 3, a computer 2 and a synchronization device 4 located at the same control line.

The video camera 3 is made and placed in such a way that a vehicle with a visible GRZ (front or rear) passes through its control zone. An analog or digital megapixel video camera with a lens can be used as suitable.

Computer 2 contains software (software), which is responsible for recognizing the burden of fixed vehicles, records the date and time of their fixation.

The satellite time synchronization device is a smart antenna that receives signals from the global navigation satellite system, which at the output gives the consumer the exact time value with reference to the national scale, as well as the 1PPS second mark for synchronization.

Remote server 5 is a hardware-software complex containing previously obtained information about the relative position of the registrars, providing collection and accumulation of information received from the registrars of the complex, processing this information to calculate the speed of vehicles, identify and record cases of speed violations by car participants.

Each registrar is connected to a remote server by a wireless communication channel, which allows for coordinated operation of system elements and data exchange.

Below is a description of the operation of the claimed complex.

At the borders of the monitored area with known speed limits for vehicles, one registrar is permanently installed. Each recorder is equipped with at least one video camera, a computer and a satellite time synchronization device and connected via a wireless data transmission channel to a remote server.

The cameras are set up and calibrated in such a way as to calculate the length of the road section in the control zone of each video camera at each turn, and the software of the complex made it possible to calculate the distance in the control zone from the GRZ TS in an arbitrary place before entering and leaving the control zone.

Then, the exact distance is measured from the control zone at the beginning of the controlled area to the control zone at the end of the controlled area using a distance meter, for example, a road wheel (curvimeter) or a laser distance meter. To do this, place a vehicle equipped with a meter in the initial control zone, start the measurement process, then move the vehicle along the road to the final control zone, where the measured value is recorded, the path traveled inside the control zones is subtracted, and a fixed distance between the control zones is obtained. The obtained value does not change during the operation of the complex and is used to calculate the average speed of vehicles on a controlled stretch of road. This measured value fully takes into account the configuration and profile of the road, which ensures high accuracy in measuring the distance traveled, and therefore the average speed.

Information on the location of all registrars, the distance along the road between each pair of adjacent registrars, and speed limits on each such section of the road are entered into the remote server 5 in advance (before use).

When the recorder equipment is turned on, the internal time of the recorder is synchronized with global time. Further, during the operation, synchronization is performed every minute, which ensures accuracy and coordination of time on all registrars of the complex.

Each registrar records all vehicles passing through the control line. The following information is stored for each vehicle:

- photo of the vehicle,

- identifier of the control line (registrar),

- recognized grez,

- date and time of fixation.

This information is transmitted to a remote server for further processing.

On the remote server, the received information is processed using special software and hardware tools, and violations of the high-speed mode are detected and recorded.

For each vehicle, the travel time between adjacent control lines is determined, and based on the data on the distances between these lines, the average speed on each controlled section of the road is calculated. If an excess of the permissible speed is detected, then for such a vehicle a package of evidence is formed:

- two photos of the vehicle recorded at adjacent borders (the boundaries of the controlled area),

- recognized Grez TS,

- date and time of fixation at each line,

- information on the location of the lines and on the distance between the lines, as well as on the limitation of the average speed on this section of the road,

- measured (actual) average speed on a given section of the road.
