Description

The utility model relates to the means of photo and video recording and monitoring compliance with traffic rules and safety at the intersection of railways and roads.

The prior art system for remote monitoring of the state of the railway track (RF patent No. 89055, IPC B61L 29/00, published on November 27, 2009), containing a video camera mounted on a support near the railway track, connected via a signal transmission means to the one installed in the control room information signal receiver. The system also includes a unit for registering the received information signal, an electronic unit for analyzing the information signal installed at the location of these cameras or in the control room with the possibility of analyzing the received image of the area of the danger zone with the detection of an object between the rails or the integrity of the rails and / or the railway embankment .

The disadvantage of this system is the impossibility of objective monitoring of compliance by drivers of vehicles with traffic rules in the railway crossing zone, as well as the need to install expensive equipment on each locomotive for broadcasting a real-time video signal.

A device for preventing emergencies at level crossings (RF patent 2284939, IPC B61L 29/00, publ. 10.10.2006), containing two video cameras placed on opposite sides of the railway crossing and connected to the control unit of the operation mode of the cameras, which in turn, it is connected with the control unit for the operation of the cross-country alarm system and with a signal transmitter of video cameras connected to a receiver installed in the premises of the station duty officer and on the rail vehicle, the output of which is connected to a computer Connected to the monitor and to the video recorder. The device also includes optical sensors associated with the unit for determining the average parameters of illumination and contrast, and a unit for recording and storing the reference signal, an obstacle detection unit is connected to the computer, which in turn is connected to monitors and an obstacle registration unit, which is connected to the executive control unit mechanisms in the room on duty at the station there is an obstacle separation unit connected to the computer and monitors and the emergency registration unit, the outputs of the latter connected to the control unit actuators and the transmission unit of information about the source of danger.

The disadvantage of this device is the inability to detect and record violations of traffic rules by road users crossing the railway crossing, including the automatic identification of vehicles that have become an obstacle to the movement of trains. The lack of the necessary evidence base obtained by means of objective control does not allow timely prosecution of traffic participants who intentionally violated traffic rules. And the latter, most often is the cause of dangerous situations in the railway crossing area. In addition, the disadvantage of this device is the need to install expensive equipment including a powerful transmitter and a broadband radio channel for transmitting a television image.

Known signal-monitoring complex of the railway crossing (RF patent No. 119314, IPC B61L 29/00, published on 08.20.2012), including electrical and electronic functional tools installed on the side of the vehicle, a warning sign and a horizontally located pair of prohibitory red lights , a video camera located with the possibility of simultaneous observation of the crossing road and signal lights.

The disadvantage of this analogue is the lack of the ability to automatically collect complete objective information about road users who violated traffic rules or created a dangerous situation for other road users.

The closest analogue, taken as a prototype, is a description of the Avtoragan hardware and software complex for video monitoring of level crossings (page with a description of the complex: http: // apeks-cbcce13c314e44587c6326b89eb28658), which was developed by Recognition Technologies LLC. The complex includes two pairs of video cameras placed on opposite sides of the railway track, infrared searchlights and a computer for data processing. The complex receives signals from the traffic light controller and the barrier in order to determine the duration of the prohibition signal of the traffic light to record violations of traffic rules by drivers of vehicles crossing railway lines.

The disadvantage of this complex is not the best location for video cameras for fixing license plates of passing vehicles. With a similar arrangement of cameras, the number plate of the fixed vehicle can be blocked by vehicles moving in the opposite direction, which will inevitably lead to a decrease in the efficiency of the complex and the appearance of errors.

The objective of the claimed utility model is to eliminate the above-mentioned shortcomings of existing systems by creating a complex of photo and video recording of traffic violations at a regulated railway crossing, which ensures high efficiency and reliability of detecting and fixing traffic violations at level crossings in combination with high performance and low cost.

The technical result is to increase the level of safety in the railway crossing zone, as well as providing an objective evidence base for cases of violation of traffic rules or dangerous situations created by road users in the railway crossing zone.

The technical result and the task are achieved in that the complex of photo and video recording of traffic violations at a regulated railway crossing includes at least four video cameras placed on both sides of the railway track and a computer connected to them containing a recognition unit for state registration marks (GRZ) vehicles (TS) and configured to transmit data to a dispatch center, while the cameras are located in pairs on both sides of the rail the roadway, where the first video camera of each pair is installed to the left of the carriageway adjacent to the crossing in close proximity to it, with the possibility of fixing license plates moving towards the vehicles across the crossing, and the second video camera of each pair is installed to the right of the carriageway adjacent to moving, with the possibility of fixing the overview frame of the crossing zone and signal lights of the traffic light.

Video cameras are arranged in pairs on both sides of the railway track (see Fig. 1). In a preferred embodiment, the first video camera designed to fix the GRZ TS is black and white, and the second video camera (overview) is color with wide viewing angles. Typically, camcorders are placed at a height of 5 to 8 meters above the ground on special supports or fasten them to existing supports, for example, power transmission towers or lighting poles.

As a rule, the surveillance video camera 2 is located at some distance from the railway track, so that a section of the road adjacent to the railway track, as well as means of crossing signaling, in particular a traffic light 3, fall into the zone of its visual control.

Surveillance video camera 2 is designed to collect evidence base that provides objective decision-making in relation to violators of the railway crossing passage rules, as well as to verify decisions already made on the basis of the saved record and indications of the crossing signaling equipment at the time the violation was recorded. It is desirable that the recognition camera 1 also enters the visibility range of the overview video camera 2 (shown by the dashed line in Fig. 1) to increase the evidence of the evidence of the latter.

The recognition video camera 1 is located near the railway track and is directed towards the oncoming traffic flow from the level crossing. This arrangement provides maximum visibility of license plates of vehicles moving towards them in the crossing zone.

In the claimed complex, the computer contains software and hardware tools that provide processing functions of information received from video cameras (capture of a vehicle’s image, recognition of a vehicle’s GRD shown in the frame) and its use to detect and record violations of traffic rules through a railway crossing.

For these purposes, the computer has a memory module, in which both the primary information from the cameras and the results of its processing flow together. The recognition unit GRZ TS is responsible for processing the incoming signal from the first (recognizing) video camera 1 on each side of the level crossing, identifying the vehicle license plate plate and recognizing the GRZ TS.

The computer may also include a module for receiving a signal from a crossing signaling controller, which receives a signal about the state of crossing and is connected to a recognition unit of the Grease Detector of the vehicle. The current state of the traffic light signal 3 from the controller is transmitted to the specified module, which, depending on the settings, can turn on and off the recognition mode of the vehicle traffic light in the crossing zone.

The composition of the claimed complex may additionally include means of voice (speakerphone) communication between the station duty officer or dispatcher and road users. This allows not only to inform the relevant services on time of a possible danger, but also to report the cause of the incident or to ask for help.

The general scheme of the claimed complex and a description of its operation are illustrated in FIG. one.

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

Each video camera (see items 1 and 2) is connected by a data transmission channel to a computer. The computer itself can be located either directly in the railway crossing zone (preferred option), for example, inside the station or inside the climate cabinet on one of the poles, or in a remote control center. The signal from the cameras continuously enters the computer, where it is further processed. The processing results, as well as the primary information is stored in the memory module.

Surveillance cameras 2 are synchronized in time with recognition cameras 1 and are responsible for capturing the overall picture of the railway crossing and the adjacent road section along with the vehicles on it.

Depending on the preset settings, camcorder 1 can operate both in continuous mode and in discrete mode, i.e. turn on and off depending on the operating mode of the crossing signaling. In the first case, the recognition video camera 1 fixes the numbers of vehicles crossing the crossing when the traffic light 3 allows and prohibits it. In the second case, the recognition video camera 1 can turn on only when the traffic light 3 prohibits, or in case of emergency.

The information received is processed and stored in a computer. Identification of violators begins after the prohibition signal of the traffic light 3 is turned on. A signal about its inclusion is transmitted from the traffic light controller 3 to the complex computer. After a predetermined time, necessary for the unconditional departure of forcedly delayed cars from the zone of railway tracks, the complex fixes a car that is in the video control zone already as an intruder. Data transmission can be carried out both via wired and wireless communication lines.

Information about the violators is periodically or in real time transmitted to the dispatch center, where it can be checked by the operator and sent to the appropriate services for administrative measures.

The evidence package contains information identifying the vehicle, the time and place of the violation, as well as information (frames) obtained using the surveillance camera 2 at the time of fixing the vehicle. The frames of the overview video camera 2 show the signal of the traffic light 3 at the time of fixation, as well as the position of the vehicle relative to the railway track and barrage vehicles. A video recording of the violation is also retained and may be provided as evidence.

Stopping a vehicle at a crossing is a direct threat to traffic safety. If the vehicle is in the moving area for a long time, the computer can automatically generate an alarm signal to alert the station duty officer or dispatcher in the remote center about an emergency situation. Using a voice communication device, the dispatcher can contact the participants of the movement to find out the causes and methods of eliminating the dangerous situation.

To fix traffic violations associated with traveling on the oncoming lane at the level crossing, the complex is made with the ability to control the vehicle direction in each lane. This function is implemented at the software level by analyzing the sequence of frames received from the recognition camera 1. When recording such an event, an overview video of the moving status is additionally recorded from the corresponding overview video camera. All materials on the recorded event are transferred to the dispatch center or the center for issuing fines.

The claimed complex allows you to effectively identify and record violations of traffic rules in the zone of a regulated railway crossing, which can create an increased danger for all participants in the movement, including trains. The main types of violations that the complex can fix:

- travel to a prohibited traffic light;

- travel on an oncoming traffic lane;

- stop on the railway tracks.

Using the proposed complex allows to increase the effectiveness of the fight against violations of traffic rules at level crossings, as well as the safety of trains due to the timely detection of a potential emergency.
