Description

The utility model relates to control and measuring equipment, namely to a mobile device for photo and video recording of the traffic situation and traffic violations by road users, can be used to equip patrol cars and vehicles of special services in order to fix administrative offenses in the field of traffic.

A radar installation for a patrol vehicle is known from the prior art (RF patent 193979 U1, publ. a radar, a searchlight, a power supply, a switching module configured to connect to the hardware and software complex of a patrol vehicle, and a video module. The body of the radar installation is made with the possibility of placing patrol vehicles with beacons in signal loud-speaking installations. The video module consists of a camera and a video sensor, which, through optical windows in the front wall of the housing, perform the functions of photo and video recording of vehicles. One of the disadvantages of this analog is that it is not a functionally independent device that allows you to implement the functions nominally assigned to it, including acting as a means of regulating the movement of road transport. The reason is that this radar installation does not contain information storage and processing facilities.

The site http://www.arsenal67.ru/nashi-produkti/kiber-sherif.html discloses information about the Cyber-Sheriff on-board hardware and software system (an updated version of the aforementioned radar installation), which, according to the developers, is capable of automatic photo and video recording vehicles at a 360° angle. This complex, according to the publication, contains TV video sensors, a Cyber-Sheriff vehicle speed meter with video recording, a computing module, a data processing and transmission unit, which includes a control unit, a power conversion unit, a remote GSM antenna and a GPS module . As in the case of the first analogue, photo and video recording of vehicles in this complex is carried out through optical windows in the body.

The closest analogue for the proposed technical solution is the AutoScanNar complex (https://usedcars.ru/articles/96369/), developed by the authors of the proposed utility model. This complex is designed for use on the roof of a patrol vehicle and is equipped in the maximum configuration with 4 video cameras that monitor the traffic situation around the patrol vehicle.

A common disadvantage of all the aforementioned analogs is a decrease in the efficiency and stability of the complex, up to complete inoperability due to the gradual contamination of the optical windows of the video cameras and the IR illuminator, as well as the need for constant monitoring of the purity of these optical windows and their periodic cleaning. This is especially critical in adverse weather conditions and heavy traffic. Contamination of optical windows can significantly reduce the efficiency, and sometimes completely block the operation of measuring equipment. This creates additional inconvenience and requires a lot of time and effort to maintain the complex. In addition, manual cleaning of the optical windows of video cameras along the perimeter of the body is unsafe, given the conditions of its operation, and when driving on roads and / or in bad weather, these measures are either completely impossible or ineffective.

The objective of the claimed utility model is to eliminate the disadvantages of these analogues. EFFECT: creation of a mobile device for photo-video recording of a traffic situation and traffic violations, which is characterized by stable efficient operation regardless of weather conditions and the environment and ensures that the optical windows of the video camera and IR illuminator are constantly kept clean. Compared with analogues, the operator's work with the proposed technical solution is safer and more convenient, since it does not require manual cleaning of the optical windows of the device housing.

The specified technical result is achieved by the fact that the composition of the claimed mobile device for photo and video recording of the traffic situation and traffic violations includes a housing inside which a video camera, an IR illuminator and a radar are installed, as well as a computer 2 and a navigation receiver 3 with an antenna, while the device contains a power supply 4 and additionally cleaning unit 5 optical windows 8 of body 1.

When developing and testing a prototype of the proposed device, the authors of the utility model encountered a problem associated with the need to periodically clean the optical windows of the body, which directly affects the quality of photo and video recording of the environment and state registration plates (GRZ) of vehicles falling into the control zone. Unlike most known systems for photo-video recording of violations of traffic rules and traffic flow control, the claimed mobile device can be placed on the roof of a patrol vehicle, and in this case it is located at a fairly small distance relative to the roadbed. In addition, the scope of the claimed device involves its operation in all weather conditions, as well as when driving on roads in conditions of active traffic. These circumstances create serious prerequisites for the ingress of various contaminants on the body of the device, especially on the surface of optical windows. Such contaminants can be dirt, dust, water drops, snow, various debris, etc. Contamination of optical windows can significantly reduce the effectiveness of such measuring and traffic control devices, since the correct operation of video cameras is of key importance for the correct and quick detection and fixing of the GRP of vehicles entering the control zone. At night, the operation of the IR illuminator also plays an important role, so the corresponding optical window on the device case must also be sufficiently clean and transparent. This is especially true when a patrol vehicle moves in a traffic stream, when the operator responsible for the operation of the device does not have the opportunity to clean the optical windows of the device case on the go.

To solve this problem, the authors of the utility model, as part of the claimed technical solution, used a unit for cleaning the optical windows of the housing, which ensures the constant maintenance of the required level of transparency and cleanliness of the optical windows of the device housing.

The unit for cleaning the optical windows of the housing may include one or more mechanical wipers, as well as washer nozzles connected to the means for storing, supplying and pumping washer fluid.

The optical window washer fluid is stored in a special container (tank), preferably located in the trunk of a patrol vehicle for ease of maintenance. The washer fluid container is connected to the nozzles by means of tubes (rubber, silicone or other suitable material), and a pump (electric pump) is used to pump the fluid, preferably located next to the indicated container in the trunk of the vehicle and powered by a power supply. This provides the possibility of supplying washer fluid to the optical windows both during the stationary operation of the device and during the movement of the patrol vehicle. As a washer fluid, both water and any other suitable fluid can be used, for example, a special alcohol-containing anti-freeze mixture in the cold season.

The washer nozzles can be installed outside the top, bottom or side of the respective optical window of the housing, depending on the specific configuration of the device and the location of the optical window on the device housing. The operation of the washer nozzles can be carried out both in automatic mode and in manual mode, depending on the configuration of the device and the working conditions of the operator responsible for its operation. In automatic mode, the operation of the washer can be configured programmatically in accordance with a predetermined algorithm and depend, for example, on the efficiency of the device, namely, on the quality (clearness) of the resulting image and the quality of recognition of the vehicle's GRZ.

The windshield wiper can be a rubber brush on a metal (or other) frame, driven by an electric motor, and making cyclic movements (similar to car windshield wipers). Windshield wipers can be installed outside the body of the device next to the corresponding optical window.

The proposed technical solution provides for the joint operation of the washer nozzles and wipers for more efficient operation of the block for cleaning the optical windows of the housing. In this case, the operation of the cleaning unit can also be carried out automatically, depending on the specific weather conditions and the environment.

In addition to or instead of the above washer nozzles and wipers, the optical window cleaning unit of the housing can also be equipped with a glass blowing line in order to protect the optical windows, for example, from icing during the cold season or blowing moisture from the surface of the optical windows arising from rain, drizzle or flying out drops of moisture from under the wheels of the vehicle in front. Air is supplied under pressure to the outer surface of optical windows through nozzles. For air supply, a separate line of connecting tubes (rubber, silicone or other suitable material) is used, which connects a special container into which air is injected under pressure by means of a compressor, which can be located in any convenient place inside the patrol car (for example, in the trunk) . The operation of the air supply nozzles can be carried out both in automatic mode and in manual mode, depending on the configuration of the device and the working conditions of the operator responsible for the operation of the device. For the automatic mode, the operation of the air supply nozzles can be configured by software in accordance with a predetermined algorithm and depend, for example, on the efficiency of the device, namely, on the quality (clearness) of the resulting image and the quality of recognition of the GRZ of vehicles. As the pressure in the air storage tank decreases, the compressor automatically pumps air into it to a predetermined level. The electric motors that drive the washer fluid, windshield wipers and pump air can be powered from the same network as the device itself.

Also, to maintain the required level of transparency and cleanliness of the optical windows of the device, fans can be placed inside the device case opposite each of the windows, which create an air flow that acts on the inner surface of the optical windows, preventing possible condensation on it.

Depending on the specific configuration of the device, instead of or together with fans, heaters for the optical windows of the device can be used, the use of which helps prevent snow from accumulating in the cold season, as well as to exclude the possible appearance of condensate on the inner surface of the optical windows. The heaters can be made in the form of flat elongated heating elements that are installed on the inner surface of the optical window.

To evaluate the efficiency of the cleaning unit for the optical windows of the mobile device case, full-scale tests of two devices were carried out - with an installed cleaning unit (1) and without a cleaning unit (2).

The tests were carried out in the spring of 2021, in Moscow, by simultaneously driving along the route “Ul. Electrozavodskaya - st. B. Cherkizovskaya - st. Khabarovsk - MKAD (inner side) - sh. Enthusiasts - ave. Budyonny - st. Izmailovsky Val - st. Elektrozavodskaya" in conditions of high humidity of the roadway.

Both devices during operation displayed the current information on the screen of the automated workstation (AWS) of the operator, who carried out visual control of the fixation of vehicles (V) and recognition of their GRZ. Visual assessment criterion: in case of gradual contamination of the optical windows, data on vehicle fixation are displayed on the screen, and there is no recognized GRZ. When fixing more than five vehicles without GRZ in a row, the operator decides on a service stop for mechanical cleaning (wiping) of the optical windows of the device case.

The test results show a decrease in the number of fixations by 40-45%, as well as an increase in the number of partially unrecognized GRZ by 2-7% and an increase in the number of vehicles in which the GRZ was not determined at all by 7-10% for a device without a cleaning unit. At the same time, the device with a working cleaning unit did not require additional service stops.

The use of the block for cleaning the optical windows of the body made it possible to significantly increase the efficiency and stability during the continuous operation of the device by maintaining a high purity of the optical windows, regardless of the situation surrounding the patrol vehicle, to increase the safety of the operator servicing the device, due to the absence of the need to leave the vehicle and manually clean the optical windows of the case. Also, the claimed solution made it possible to make the maintenance of the device easier and more convenient.
