The disadvantage of this complex is the low information content.

This technical solution is selected by the authors as a prototype.

The technical result is to increase the information content of the signal-controlling complex.

The technical result is achieved by the fact that in the signal-control complex of the railway crossing, consisting of electrical and electronic functional means, installed on the side of the road a warning sign, a pair of prohibiting red lights, a video camera with simultaneous observation of the crossing path and signal lights, next to a pair of prohibiting red a warning yellow light is installed, and the functional means are configured to be switched on with red lights at the same time and burning along with them, next to a pair of prohibiting red lights, an enabling green light is installed, signaling the opening of a level crossing for vehicles, in the surveillance zone of the video camera there are barriers with bars that are equipped with switchable signal lights of green, yellow, red color and power mechanisms with electric drives , according to the invention, four oversized sensors are additionally introduced, two on each side adjacent to the road, two LED screens on each side of the level crossing and and counting points in the even and odd directions, each counting point consists of two wheel passage sensors, a unit for rolling stock units, a radio modem, each of which is connected to the power supply, and two central receivers that are connected to two LEDs, one each sides of the crossing, and with two oversized sensors on both sides of the road, and the signals from the counting points are sent via radio modems to the central receivers.

The introduction of oversized sensors, counting points, central receivers and information screens into the signal-control complex of the railway crossing allows you to increase the information content by expanding the following indicators about the oversize in height, the direction of train movement, its speed, and the time remaining before moving across the railway.

On the figure. - General view of the signal-control complex of the railway crossing.

The signal-control complex of the railway crossing consists of a railway track - 1, a highway - 2, a moving car - 3, a warning sign - 4, a pair of red lights - 5, a yellow light - 6, a video camera - 7, a green light - 8, a barrier beam - 9, red lights - 10, yellow lights - 11, green lights - 12, oversize sensors - 13, 14, 22, 23, information screens - 15, 24, central receivers - 16, 25, wheel passage sensors for railway rolling stock - 17, 18, 26, 27, counting units of rolling stock units - 19, 28, pa diomodems - 20, 29, power supplies - 21, 30.

The signal-controlling complex operates as follows.

When the railway transport is in a safe zone for moving, outside the approach area, the signal lights and the video camera of the signal-control complex are turned off and the vehicle 3 can freely pass along the road 2 through railway 1. When the train approaches the approach area, the video camera 7 turns on and the warning light comes on yellow light 6. At the same time or with a certain delay, alternately flashing red lights turn on 5. This means a ban on the entry of vehicles mouth 3 to the railway track 4 with a stop of vehicles at the stop line of the warning sign 4. The transport that entered the crossing must release it before the train enters the approaching area. At this moment, the yellow light 6 goes out, and the red lights 5 continue to burn and turn off after the train releases the crossing.

When the train approaches the approaching section, the green light 8 and the green lights 12 located on the barrier 9 are turned off, they are replaced by the yellow light 6 and the yellow lights placed on the barrier 9 11. At the same time or with a certain delay, the red lights 5 and the red lights placed on the barrier 9 lights 10. This signals the imminent closure of the barrier 9 and the ban on the entry of vehicles 3 onto railway 1, and the vehicle that entered the crossing should release it. When the train enters the approaching area, the yellow fire 6 and the yellow lights 11 go out and the red lights 10 on the barrier 9 turn on, the beam of the barrier 9 starts to lower. All red lights 5 and red lights 10 continue to burn, and after the train releases the crossing and raises the beam of the barrier 9, it goes out. In place of the red lights 5, the green light 8 and the green lights 12 located on the barrier 9 are turned on, allowing the movement of vehicles on moving.

If the vehicle is oversized, the signals from the oversize sensors 13, 14, 22, 23 are transmitted to the central receivers 16, 25 and information screens 15, 24, on which information appears about the excess of the permissible height standard.

Two counting points, which are located at a distance from the crossing, provide sufficient time for timely notification of traffic participants at the crossing with information about the train situation in the railway crossing area. Each counting station includes two wheel passage sensors 17, 18 and 26, 27, a unit counting unit for rolling stock 19 and 28, a radio modem 20 and 29 for transmitting information to central receivers 16 and 25 over the air, depending on the direction of movement of the railway rolling stock . To increase the immunity from electromagnetic interference, the counting stations have autonomous power supply from power supplies 21 and 30. The counting station provides tracking of the train progress by counting the number of axles passing in the control zone of the wheel passage sensors 17, 18, 26, 27, determining the speed and acceleration of the train , determining the direction of train movement and transmitting information over the radio channel to the central receivers 16, 25. Central receivers 16, 25 provide data reception over the radio channel, processing information from the account GOVERNMENTAL claims and transmitting information over a wired link to information screens 15, 24 as well as control the operation of the two information screens 15, 24, one on each side of the crossing. Information screens 15, 24 are used to inform drivers of vehicles and pedestrians at the crossing about the approach of the train, the time remaining before its passage through the crossing, speed and direction of movement, as well as exceeding the overall height and other circumstances at the crossing (for example, repair work) . Information screens 15, 24 are installed above the level crossing on each side in the line of sight for drivers of vehicles.

The signal-control complex of the railway crossing contains acoustic signaling devices (known calls, howls). The signal-control complex includes electrical and electronic equipment. By means of them, the signals are turned on / off, the barrier is closed-opened and other operations are described in the described sequence, specific time intervals are set based on the characteristics of a particular section of a railway crossing (traffic schedule, railway track width, etc.).

The signal-control complex of the railway crossing allows you to reduce the accident rate at level crossings, increase the level of road traffic safety at level crossings due to the increased awareness of all traffic participants and the reduction of vehicle downtime by 5-10%.
