Description

The technical field to which the utility model relates.

The utility model relates to devices for automated control of the movement of vehicles (hereinafter - TS) and detection and fixing of violations of traffic rules (hereinafter - SDA) by a vehicle, including for fixing vehicles that exceed speed, and more specifically to universal video fixation devices traffic violations.

State of the art

Known stationary device for video recording violations of traffic rules "KRIS-P", http://www.simicon.ru/eng/product/gun/archive/photoradar_kris_p.html , (as well as a similar "ARENA", http: // olvia. com / arenamobile) containing an electronic unit mounted at the height of human growth on a support in the form of a tripod and a battery pack placed on the ground at the base of the tripod. This device allows the possibility of autonomous operation in the absence of an electrical network and provides the ability to quickly replace the battery. This device only works in stationary mode. The disadvantage of this device is the inability to measure the coordinates of targets located in the field of view of the radar and camera. This leads to the fact that, despite the presence of license plate recognition, the device is not able to simultaneously determine the speed of several vehicles, which leads to the passage of a significant part of the traffic stream and reduce the efficiency of identifying violators.

Known mobile standalone video capture device (RF patent "BINAR" (RF patent No. 2472227 publ. 01/10/2013, http://www.simicon.ru/eng/product/gun/binar.html ), which is mounted on a bracket inside the car and provides video recording of the transport stream and measuring the speed of the fastest vehicle in this stream.The device takes measurements both in stationary mode and in driving mode. The device receives information about its own speed from the radar signal. The disadvantage of this device is the lack of capabilities measurement of coordinates and automatic recognition of state license plates (hereinafter - GRZ) of vehicles and, as a result, the need for the operator to participate in the procedure for identifying a speeding offender.

Famous vehicle speed meter "MultaRadar CD moving" ( https://fccid.io/ANATEL/01361-10-02906/Fotos-Externas/5944FD77-52E6-4FB2-B392-B9ED12017E06/PDF ), ( http: // www .unikart.su / multaradar-cd-moving.html ), and the similar “GATSO Millia” ( http://massprivatei.blogspot.com/2013/02/a-new-hidden-photo-radar-system-called. html ), ( http://www.radarmobilenouvellegeneration.com/modeles-radars/gatso-millia.php ), ( https://www.radars-auto.com/info-radars/modele-radar/gatso-millia. php ), which is capable of measuring vehicle speeds both in stationary mode and in driving mode, can be installed both inside the car and on the side of the road. The meter includes a video camera, a backlight device, a processor computing unit, a unit for determining its own speed, a radar, and batteries. Blocks are placed in a car or are arranged in a single system on a roadside tripod and connected by cables. The disadvantages of this solution are the presence of several separate electronic units from which the meter is assembled, for which, in preparation for work, it is necessary to perform a number of installation, installation and calibration operations and provide these units with cable interconnects. When mounted in a car, various blocks of this meter are placed and fixed on different structural elements of the car, in particular, the radar is mounted in front of the license plate on the front bumper, the video camera and control panel are in the passenger compartment in the passenger compartment, the battery packs and the computer processor block are in luggage compartment. The blocks are connected by special cables that are pre-laid inside the car. This placement of the meter makes it almost impossible to quickly dismantle it for use in a stationary mode on the side of the road without a car. In addition, the meter does not have the ability to measure vehicles moving in the same direction slower than a car with a meter, it also lacks the ability to automatically recognize state license plates.

Known stationary device for video recording violations of traffic rules Cordon-M2P, http://www.simicon.ru/eng/product/gun/cordon_m2_p.html , which is able to recognize license plates and measure the coordinates of controlled vehicles, determine the direction of movement and speed of all vehicles means visible in its control zone. The device is a radar, a camera and a processor module, which are combined into a single complex, which is installed above the road or on the side of the road and is designed to control the speed limit, as well as detect and photo-video record other violations of the Traffic Rules (SDA).

This technical solution is the closest to the proposed solution and is taken as a prototype.

The disadvantage of this device is its limited functionality, since it is not designed to work in a moving car or other carrier vehicle. The design of this device in combination with the mounting device on which it is mounted is not intended to be fixed in a vehicle; the device does not have the ability to measure its own speed and calculate the speeds of vehicles that appear when moving in its field of view. Thus, it cannot be used in driving mode to control speed and identify traffic violations associated with this, which significantly limits its functionality and reduces the range of its applications.

The technical problem solved by the utility model is the difficulty of placing the device in a moving car, since the layout of the prototype device does not allow its adaptation to the dimensions of the vehicle carrier. In addition, the inability to measure the own speed of the vehicle carrier does not allow for the correct measurement of the speed of vehicles that appear during movement in the control zone of the device.

Utility Model Disclosure

To solve this technical problem, a photo-video fixation device for automatically recognizing state registration marks, measuring the speed and coordinates of all vehicles visible in the control zone, comprising a radar, a navigation module, a processor module and a video camera connected to them, configured to be installed in a moving vehicle, is proposed media and automatic measurements in motion mode, and the processor module is configured to calculate speeds controlled vehicle based on its own vehicle carrier speed.

The processor module is preferably configured to connect to the data bus of the vehicle carrier and calculate its own speed both from the signals received simultaneously from the modules connected to it and from the signals of one of them in accordance with the expression

VTC = Vrel ± Vproperties, where

VTC - speed of the controlled vehicle,

Vrel is the speed of the controlled vehicle, measured in relation to the moving vehicle,

Vproperty - own speed of the vehicle carrier

moreover, the +/- sign is automatically selected depending on the direction of travel (oncoming / passing) of the controlled vehicle.

In addition, the processor module is preferably configured to provide an unambiguous binding of the speed measurement results to the recognized HRDs of the fixed vehicles both in stationary mode and in motion mode.

The processor module can be configured to automatically change the permissible speed limit threshold depending on the category of the fixed vehicle (passenger, cargo, bus) both in stationary mode and in driving mode.

The processor module can also be configured to automatically recognize the vehicle category in both stationary mode and in motion mode.

The navigation module is preferably configured to automatically associate the location of the device with electronic road maps containing information about the coordinates of the zones of speed limits and the magnitude of these restrictions.

Preferably, the device is adapted to be mounted on a mounting device for operational installation both inside and outside the TC carrier, as well as with the possibility of adaptively changing the layout for the specific dimensions of the TC carrier.

The technical result achieved by using the utility model is to expand the functionality of the device, namely, to take measurements both in stationary mode and in motion mode.

The proposed device can be used both in driving mode from a moving vehicle carrier, and in stationary mode when placed on the side of the road using a portable tripod, or using a stationary high-altitude support. The speed measurement in motion mode is ensured by the fact that information about the vehicle’s own speed is received and processed in the processor module. This information can be obtained from the navigation module connected to it, either from the radar or from the data carrier of the vehicle, containing information from the car speedometer. To increase the accuracy of measurements, it is also possible to simultaneously use data from all the sources mentioned. The availability of information about the vehicle’s own speed, as well as data received from the radar about the speed of the monitored vehicles in relation to the vehicle and the direction of their movement, makes it possible to determine the speeds of the monitored vehicles in the control zone of the device according to the formula

VTC = Vrel ± Vproperties, where

VTC - speed of the controlled vehicle,

Vrel is the speed of the controlled vehicle, measured in relation to a moving carrier vehicle,

Vproperty - own speed of the carrier vehicle,

moreover, the +/- sign is automatically selected depending on the direction of travel (oncoming / passing) of the controlled vehicle.

Automatic license plate recognition in combination with measuring vehicle coordinates allows you to automatically identify and identify cars that violate the high-speed mode, while simultaneously checking recognized license plates on search databases (stolen vehicles, bailiff bases, OSAGO bases, a base for transporting people buses, etc.) loaded into the device’s memory.

The ability to automatically determine the vehicle category in combination with the automatic detection of speed limit zones allows you to correctly change the level of the speed limit threshold depending on the brand of the intruder and its location.

Utility Model Implementation

The video monitoring device of FIG. 1 comprises a radar 1, a video camera 2, a processor module 3, a navigation module 4, an IR illuminator 5, and a power supply unit 6. The camcorder 2 is connected to the processor module 3 and provides loading into the processor module 3 images of the vehicle in digital form. An IR illuminator 5 is connected to the camcorder 2 for additional illumination when working in the dark. Radar 1 is also connected to the processor module 3, which provides data to the processor on the speed and coordinates of all moving objects in its field of view, including the proper speed of the vehicle. The navigation module 4 (satellite receiver) connected to the processor module 3 provides information on the coordinates of the location of the vehicle, and can also provide information about its speed. Additionally, this information can be obtained by the processor module 3 and from the data bus of the vehicle (not shown in Fig. 1). All modules 1-5 of the device are connected to a power source 6, which can be used as an on-board network of the vehicle, as well as an autonomous battery.

In FIG. 2-3 show the possibility of transforming the layout of a universal device for photo-video monitoring. In particular, in FIG. 2 shows the layout when the radar is located under the camcorder. This layout is standard and is used for placement on both vehicle carriers (an example is shown in Fig. 4) and on the side of the road (Fig. 6). In FIG. Figure 3 shows an arrangement with placement of a radar on the side of the camcorder. This arrangement is more compact than that shown in FIG. 2 and is intended for placement in automobiles having a low-height interior. An example of such placement is shown in FIG. 5. The device of FIG. 4-6 is mounted on mounting device 7 (tripod). The height of the tripod 7 can be adjusted to the dimensions of the used vehicle carrier. In addition, the elements of the device and the mounting fixture are connected by swivel joints, which allows you to optimize its design when installing the device in a car of a particular brand. The device can also be mounted on the roof of a car, on a patrol police motorcycle, or on a support on the side of the road. The device can be used to control the speed mode from a moving vehicle carrier.

The device of FIG. 1-6 works as follows.

In an embodiment, the mounting fixture (tripod) 7 is installed in the luggage compartment of the vehicle and fixed to the elements of its structure. On the working platform of the mounting fixture 7, a photo and video recording device is fixed so that the video camera 2 and the radar 1 are directed towards the rear window of the vehicle. The installation height of the device is chosen so that in the field of view of the radar 1 and the lens of the video camera 2 is the rear window of the car, through which video surveillance and speed measurement of controlled vehicles moving behind the vehicle carrying the device are performed. The power cord of the device is connected through the connector in the trunk to the vehicle electrical system or to an additional battery located in the trunk. With the beginning of movement, the device measures the speed of all targets in its field of view with respect to the moving vehicle, as well as the proper speed of the vehicle. Based on these data, the processor module 3 provides the calculation of the speed of each vehicle from appearing in the control zone in accordance with the expression

VTC = Vrel ± Vproperties, where

VTC - speed of the controlled vehicle,

Vrel is the speed of the controlled vehicle, measured in relation to a moving carrier vehicle,

Vproperty - own speed of the carrier vehicle,

moreover, the sign (+/-) is automatically selected when calculating, depending on the direction of travel (oncoming / passing) of the controlled vehicle.

At the same time, the device recognizes the gas distributor and the categories of fixed vehicles, and also ensures the correct assignment of the measured speed to the recognized one. Automatic recognition of categories of vehicles allows you to correctly determine the allowed speed threshold for each of them and record in the memory photo and video materials that concern only violators of the high-speed mode. The device receives data on the value of the allowed speed threshold on this section of the road from the navigation module 5 associated with the electronic road map stored in the device’s memory. This map contains all the necessary information about the coordinates of road sections and thresholds for speed limits on these sections. The card is loaded into the device’s memory in preparation for patrolling. The device determines the speeds of both oncoming and passing vehicles, including those that move faster and slower than the car on which the device is installed.

When using a mounting device of a different design, such a device installation is possible in which the vehicles are fixed in front of the moving vehicle carrier. To work in the dark, the device can be equipped with an IR spotlight 5.

Dismantling the device from the vehicle carrier for stationary operation is carried out by disconnecting the mounting device 7 from its structural elements, after which the photo and video recording device together with the mounting device is transferred to the side of the road. Stationary operation is also possible directly from a parked vehicle carrier without dismantling the device.

Thus, the proposed utility model has enhanced functionality compared to well-known analogues, because thanks to an improved processor module that allows you to calculate the proper speed of a moving vehicle, the device can be used both in stationary mode when placed on the side of the road, and in the mode of movement from moving vehicle carrier.
