Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for securing a level crossing against the entry of vehicles during a warning signal, in particular a device for securing a level crossing.

BACKGROUND OF THE INVENTION

Prior art systems of railway crossing safety devices do not solve any obstacle in any way, for example a vehicle that can get stuck when passing between fallen barriers and thus remain on the rails, thereby causing an accident, collision with the approaching train. All bolts are lowered simultaneously, so that the vehicle which enters the rail even when the bolts are lowered and thus is in the rail, its exit being blocked by a bolt behind the rail which has meanwhile been lowered so that it cannot exit the rail. Although the gates are modified so that the vehicle could forcibly pass them, but psychologically it discourages some drivers, they leave the vehicle, leaving it in the track, causing an accident. The driver has no information about an unexpected obstacle, and thus detects such an obstacle only visually, which is too late to prevent an accident. Vehicles are only secured against the entry to the level crossing after the audible warning signal is triggered by the glow of two side-by-side alternating flashing lights, which occurs, and the vehicles occasionally enter the level crossing even after the beginning of the audible warning signal.

SUMMARY OF THE INVENTION

The shortcomings of the prior art are solved by the invention of a vehicle anti-roll-over device in the event of an alarm which, when the barrier system is triggered, first triggers the barriers from the driver's perspective, in front of the rails. which arrived on the rails just before the barrier in front of the rails, leave the rails in time or are simultaneously triggered, the detector preferably detecting the track space and, when an obstacle for the train is detected, delays or stops the rails behind the rails lifts to the non-lowered position until the exit of the track is an obstacle when the barriers behind the rails lower.

At the same time, the device sends an alarm to the train control center and / or to the arriving train by means of a wireless link. At the same time, the device preferably triggers an alarm siren and, preferably, a voice message to release the tracks.

Preferably, the camera transmits video from the crossing area to the control room and / or to the train set. The technical device in the train set preferably informs the driver of an obstacle, and this reduces the train speed so that it can brake or slow down the train in good time, or the train control unit automatically controls the train set.

Advantageously, an additional crossing signalization is visible on the access road in front of the barrier system, visible to the approaching vehicles, preferably a one-color to three-color traffic light, similar to a traffic light at a road junction. This will ensure that the vehicle is stopped in red after the start of the warning signal, preferably the ring, before the bolts are lowered. The communication module, which is connected to the control unit which controls the barrier system, transmits data on the crossing situation, in particular, on the possible crossing obstacle and the status of the crossing and safety equipment to the train and train control center preferably directly and / or to the server to which the elected participants have access, which are: train set, dispatching, train control, firefighters, police, other participants. The control unit is connected to a detector and cameras and other sources, from which the status of the barrier system receives the control unit, which preferably controls the barrier system, the signal, the pre-traffic light, the voice unit and the siren.

The control system controlled by the control unit is in the control standstill state when all the barriers in front of the rails and the barriers behind the rails of which the system consists are in the open position. In the process of closing the barrier system, a signal is activated, preferably consisting of a signal of two side by side alternating flashing lights. After an adjustable time, the gates in front of the rails begin to lower. And then after an adjustable time, preferably the anticipated time required to leave the track by a vehicle, the barriers behind the rails are lowered. Barriers are triggered simultaneously or barriers behind the rails are delayed after an adjustable time from the start of the barrier warning system.

Advantageously, the barrier detection sensor in the barrier system area detects the barrier system area on the rails and, upon activation of the barrier warning signal for the detection of an obstacle for a train, for example a vehicle, sends a signal to the control unit controlling the barrier system. , if they are already lowered, it lifts them up until the space on the rails leaves the obstacle. At the same time, the communication module invokes 9

Preferably, the communication unit sends alarm and / or camera images directly to the train set via the wireless link to the train set and to the other selected subscribers via wireless communication.

At the same time, an alarm siren will sound in the region of the barrier system to indicate the need to quickly remove an obstacle such as a vehicle. Preferably, a voice message is produced from the voice unit to release the tracks. Advantageously, the camera transmits a video transmission of the scene of the barrier system space via the communication module to the control room and preferably to the train control unit from which the video is displayed on the driver's monitor. Data and / or voice communication with the control room is carried out wirelessly. The train set upon receiving the obstacle information informs the train set driver visually, preferably on the monitor display or by an indicator light, or acoustically, preferably by a tone or tone from the loudspeaker. The driver reduces the train speed manually or the control unit does so automatically, preferably gradually, so that it can stop in time if the obstacle is not removed. Advantageously, a display is provided on the label with a numerical indication indicating how much time is left to lower the barriers in front of the rails. Preferably, a barrier display is shown on the flag indicating symbolically open barriers, preferably in white or green, which turns red, and the display symbolizes the falling barrier before the barriers in front of the rails begin to fall. Preferably, a light traffic light, preferably one to three-color, visible to vehicles arriving at the barrier system, preferably similar to a three-color traffic light, is located at and / or at an optional distance in front of them. Simultaneously with the signaling signal, the green light changes to orange and then to red before the gates in front of the rails are lowered. A single-color traffic light signals a red light, a two-color traffic light turns orange. Preferably, the signaling signal is replaced by a traffic light.

Preferably, the communication module sends an alarm and preferably camera shots to firefighters, police, emergency controllers so that they can prepare to exit in the event of a collision in the area in the barrier system.

The camera sends the police all the necessary data, such as the vehicle registration number, for eventual recourse to a party, such as the driver of the vehicle, that caused an obstacle to be placed on the track. If the obstacle is a vehicle that leaves the barrier area without an accident, the police are preferably equipped with a road display controller instructing the vehicle to wait for the arrival of the shelf, for example to descend the parking lane and wait for the police to arrive there.

Advantageously, the communication module sends data to a server to which selected participants have access, for example, a train control center, train set, via the Internet.

• ······························································ · · ·· ···· ··· ·

The selected participants have access to the situation data of all barrier systems which are equipped with a communication module and associated units for sensing and / or detecting obstacles and / or sensors, preferably formed by cameras. Advantageously, a train set detector is provided on the track which, when detecting a train, preferably at a greater distance than a visual one, warns against a level crossing by a horn that the train is arriving and preferably a voice announcement announces an arriving train. Advantageously, a camera system preferably comprising multiple cameras of the camera system upstream of the barrier system is provided on the track, emitting a live train arriving, preferably when switching to the cameras the train is passing by to the monitors visible to the incoming drivers to the barrier system for the psychological effect of preventing entry into the barrier system area at an audible warning signal. Preferably, the distance of the train set from the level crossing is shown. Advantageously, the incoming train is also transmitted to the dispatching server and other subscribers via a wireless link or a live view of the incoming train.

The selected participants are equipped with a display device, preferably comprising a computer with a monitor, which is adaptable to one or preferably multiple on-screen displays to view multiple barrier systems at a glance. Thus, a train driver can watch live barrier systems sensed by cameras that are on the route he is traveling ahead of time.

The device for securing the passage of vehicles in the event of a warning signal comprises a control unit which controls a barrier system comprising a signal. The control unit controls the barriers, semaphore, voice unit, alarm siren and receives information from an obstacle detection sensor in the area of the barrier system, camera and other information sources, and controls the voice unit. It sends information via the communication module to the server, which can be accessed by selected participants, for example, a train set, train traffic control center, fire brigade, other participants, police, which advantageously control the road display. The communication module is adaptable for direct connection with selected participants.

The level crossing device contains a right area, which is detected by a right sensor system. If this sensor system detects a right obstacle in it, it prevents the right barrier behind the rails from lowering. If the control unit is already partially or fully lowered, it will only lift and allow it to start when the obstacle is not detected by the sensor system. The position of the "left" "right" bar is viewed from the S direction. The position "in front of the rails" and "behind the rails" is taken from the driver's point of view in the direction of his arrival at the level crossing. It works similarly for the left-hand space. 4 4 4 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 ···· · ·· ······· · Sensor system left with sensors, and detecting obstacle left. The barrier system shall include a right-hand barrier behind the rails, a left-hand barrier in front of the rails, a right-hand barrier in front of the rails and a left-hand barrier behind the rails controlled by the control unit. delay.

The right sensor system is preferably comprised of a plurality of sensors, preferably a first right in front of the rails, a second right in front of the rails, a first right behind the rails and a second right behind the rails, which detect passing vehicles also when the gates are raised. whether the ringtone is activated or not. In case there is no match in the detection of all sensors, the barrier system will trigger an alarm in the train control center through wireless communication to eliminate the fault. The left sensor system works similarly.

The level crossing device preferably comprises a traffic light located at an optional distance, e.g. 50 m, from the barriers.

The traffic light is preferably a tricolor traffic light or a two-color traffic light or a light signal of two side-by-side alternating flashing lights.

A traffic light placed at an optional distance in front of the barriers with a "STOP" signal stops vehicles arriving at the barriers ahead of them at the time of the warning signals of the level crossing warning lights before the barrier is triggered. Then the control unit switches the signaling to "LEFT". The vehicles can continue to travel to the latches already in place to prevent them from entering the crossing.

Thus, the level crossing detection unit detects the beginning of the warning lights signaling with an optical sensor and the triggering of the bolts by the sensor of the triggering of the bolts or of both phenomena simultaneously by the camera sensor. Alternatively, the detection unit detects the alarm ring preferably by an acoustic sensor.

The activation of the "level crossing warning lights", eg by alternating blinking of two red lights, is detected by this detection unit, which is used in the event that a direct electrical connection of the link to the warning device is not possible or desirable; signaling and ringtones connected directly to the electrical crossing signaling equipment. In the case of using this detection unit, preferably consisting of an optical sensor, the unit for transmitting the warning light activation information is connected to the control unit. • A signaling unit by means of a link, which is optionally implemented by means of wires and / or or wirelessly. It transmits the warning light activation signal to the control unit, which switches the signaling to "STOP", preferably by a red light of a traffic light, preferably consisting of a three-color traffic light. The barrier trigger information is sent by the detection unit, preferably formed by the trigger sensor, to the control unit, which sets the semaphore back to "OFF", preferably green light, which preferably follows the orange light.

If the traffic light consists of a two-color traffic light, it shines with a red signal light when it is switched to "STOP". When it is set to "LEAVE" it flashes with an orange signal light or does not indicate. If the traffic light is a light signal, when it is switched to "STAND" it flashes alternately with red lights placed next to it and when it is switched to "LEFT" it is switched off.

The level crossing detection unit is preferably formed by an optical and / or acoustic sensor and / or a camera sensor and / or a lowered barrier detection sensor. At the beginning of the ring, the traffic light is set to "STOP", at the end of the ring to "LEAVE".

The warning light sensors, optical and acoustic, are preferably located directly on the barrier device of the bolts or on a separate forward sensor column.

The maximum distance of the traffic light to the barriers is preferably chosen so that vehicles at the maximum permitted speed, for example 50 km / h, travel this distance with a margin so that they preferably reach the barriers just after the warning lights flash when the barriers are still up. , so that in the event that vehicle drivers fail to comply with the traffic rules and drive into the crossing despite the activation of the hazard warning lights, they should have sufficient time to safely and safely pass the crossing before the gates are triggered. The distance is preferably determined according to the time preceded by the warning signal prior to the opening of the barriers, which begins approximately 30 seconds after the crossing warning lights flash. Just before the barriers are triggered, no more cars will pass through the barriers as they are stopped by a traffic light in advance.

Although the control unit will set the traffic light to “OFF” after the bolts have been lowered, the vehicles, if originally stopped, can now arrive at the latches already in operation.

The next semaphore cycle to "STOP" is initiated the next time the warning lights or ringtones are activated.

Optionally, the traffic light is set to "LEFT" only when the hazard warning lights flash, that is, when the gates are raised and not when the gates are lowered. This signaling device is also suitable for unprotected level crossings where the barriers are not installed.

Advantageously, a deceleration section is placed in front of the traffic light with a traffic sign "Maximum permissible speed", for example 30 km / h. Advantageously, a traffic sign "End of all prohibitions", preferably a traffic sign, which terminates the speed limit, is located downstream of the deceleration section. This sign is preferably activated depending on the activation of the "Maximum speed limit" traffic signs, preferably activated in conjunction with crossing warning lights or traffic lights. The traffic sign is located on a separate post or on a post of a "crossing barrier".

The deceleration section of the barrier crossing is preferably implemented to slow down the traffic of vehicles before the activated barrier. The level crossing warning lights are activated and start to indicate, preferably by blinking, the onset of the barrier, and at the same time the selectable number of traffic signs "Maximum speed limit" is activated, which lights up and displays an adjustable speed, for example 30 km / h. They are optionally deactivated when the latch is triggered or after the hazard warning lights have been deactivated.

To accentuate the approach of the barrier opening, the "barrier crossing" traffic signs are preferably illuminated and / or are preferably provided with orange signal lights, and, preferably alternately, flash, at the same time as the warning lights, indicate the upcoming barrier opening.

The pre-crossing signaling device is preferably also used for crossings without barriers to prevent entry to the crossing at the time of arrival and crossing of the train, which is signaled by the control room signal to the control unit which controls the signaling devices for stopping and decelerating the vehicles.

Optionally, the traffic light is preferably formed by two red signal lights of two side-by-side alternating flashing lights, which are activated for the "STOP" signal and switched off for the "OFF" signal.

Preferably, a traffic light countdown timer and a traffic light highlighting the traffic light with inscriptions and / or symbols, such as "STOP, 20s" as a countdown time countdown, and "CAUTION RED CAMERA" with driver information, wherein the sign is preferably activated when the hazard warning lights are activated.

Advantageously, a camera model is installed in the route to achieve greater driver discipline.

This camera can be replaced by a real camera.

• · · · · · · · · · · · · · · · · ·

A simplified version of the level crossing device is completely omitted.

The signaling device for stopping vehicles before crossing may be supplemented by a combined deceleration section, by means of which the deceleration is realized both by the visualization of the activated traffic sign reading when the hazard warning lights are triggered, but also by the radar unit, preferably with a radar unit in front of the traffic sign , if it registers a vehicle which exceeds the maximum permissible speed displayed on it and which is adjustable. Advantageously, a traffic sign "End of all prohibitions" is located behind the traffic sign. Advantageously, there is a vehicle speed camera scale which is replaceable with a real camera, so that there is an optional saving compared to when a real camera is fitted, since the driver does not know when each camera is deployed. For greater effect, the light on the camera dummy flashes while the vehicle is passing to make it appear to be recording.

Optionally, the combined deceleration section can be fitted multiple times to increase the effect. It can be used in road traffic at crossings with or without barriers. In this case, the traffic sign is activated only from the radar unit, which can also be placed in the traffic sign.

Preferably, the combined deceleration section is followed by a stop section whose radar unit converts the traffic light to "STOP", preferably red, when the vehicle arrives at a speed above the currently valid adjustable value, even though the crossing warning lights are not activated. When activated, they will automatically reset this to “STOP”.

The radar unit is preferably adapted to be adjusted to either a speed not reduced, for example, 50 km / h, or reduced, for example 30 km / h, when the traffic sign is activated and the traffic sign is not activated or not deployed. The speed on the radar unit is adjustable to a speed that is selectable above the highest speed limit to achieve the selected speed tolerance.

The stop section can be used in traffic even without barriers. In that case, the traffic light is only a radar unit. When the hazard warning lights are activated, the traffic sign is not activated to maintain a valid speed reduction, for example 30 km / h. The camera mock-up is preferably also placed on a traffic light, preferably on a traffic sign post. Advantageously, dummies indicating speed measurements are placed in front of the dummies to increase the efficiency of the dummies. On the display of the radar unit located in front of the traffic light. · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · In addition to the actual measured speed, the sign preferably also displays the sign slow to a certain speed, for example 30 km / h, referring to the speed indicated on the traffic sign, that follows.

The model-interchangeable camera captures not only the speed of the vehicle, but also the non-stopping of the red traffic light.

An additional barrier to the passage of the driver to the bolts can be applied if it has passed the red traffic light. The detector formed by a camera or a sensor at the edge of the lane preferably controls the traffic sign "No entry of all vehicles" and / or the traffic sign "Commanded driving direction", where the driver can see the waiting sign at the police. it is prevented by a barrier, preferably remotely controlled. Preferably, the communication unit is adapted for voice communication with the supervisor and / or the police.

The level crossing device according to the invention can also be applied against passages when the hazard warning lights flash with the help of traffic lights located at a junction and a pi

A ·

Traffic lights control intersections in the usual way by means of a control unit to which they are connected by means of joints. When two side-by-side alternating intermittent traffic lights control the traffic lanes “A” from which the barrier is approaching, they switch to “STOP” mode, in which they are lit red, and if they are in a different color, they turn to red way, that is, from green to orange. This prevents passage from lanes “A” to barriers. The lane traffic lights “B” leading from the barriers turn green so that the vehicles can leave and no traffic lanes can form that could block the crossing.

The activation of the light signal is preferably detected by a warning light sensor which is connected to the control unit by a link.

The traffic lights are switched from "STOP" mode to the conventional junction control mode when the barrier is triggered, preferably upon detection by the barrier detector detection sensor and / or the signal light sensor indicating the end of light activation, the information being transmitted over the link.

Vehicle sensors detect vehicles traveling in lane 'B' from the bolts and, in the case of a detected vehicle, switch the junction control so that these vehicles preferably have a green light to prevent the formation of traffic obstruction.

The vehicles are stopped in the "STOP" mode only for the duration of the signal activation until the latches close, ie for a relatively short time, about 20 seconds.

· · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·· · · · · · · · · ·

Then the junction control switches to normal operation and the vehicles cross the controlled junction to the already-opened gates so that they cannot pass over when the hazard warning lights flash.

Vehicles between intersections and crossings at the time of signal activation and "STOP" mode arrive at the very beginning of the activation of the hazard warning lights, so if they fail to respect them, they have about 20 seconds for a relatively safe barrier crossing before they start. Other vehicles for which crossing would be risky are already held by traffic lights.

Or the traffic lights do not control the intersection at the time of the lift barriers, the traffic lights are off or flash orange. Preferably, the "B" direction traffic light is not installed, and the vehicles in this lane are constantly free to pass.

If the signal is activated, the color of the lights will change from orange flashing to red in a preset manner until the barrier is triggered, turning back to flashing orange.

It is preferred to provide a crossing safety device with increased safety which is achieved by combining the vehicle stopper until the barrier is triggered, preferably with a deceleration section using road signs changing the maximum permissible speed, and preferably using a voice unit. Traffic signs varying the maximum permissible speed are preferably illuminated and are preferably formed by a set of LEDs or in a mechanical design, preferably with flip-flops.

The vehicle stop for the time until the barrier is triggered is constituted by a command signaling preferably consisting of a tricolor traffic light or an alternating flashing traffic light. The signaling is activated at the moment of the start of the warning ring of the override safety device for stopping vehicles and deactivated when the gates are triggered, preferably it is activated for the duration of the warning ring. Preferably, a camera recording a vehicle that has gone red is located on the vehicle stop post.

The stopper for vehicles exceeding the maximum permissible speed is preferably a tricolor traffic light and is activated when the vehicle exceeds the maximum permissible speed given by the traffic sign changing the maximum permissible speed or, in the absence of the activation, by the decree or by the previous traffic sign. and the stopper is preferably deactivated when the bolts are lowered.

Advantageously, a deceleration section is provided upstream of the vehicle stop until a barrier is provided, preferably with a traffic sign changing the maximum permissible speed or more. Traffic signs changing the maximum speed limit, preferably two, for example, 30 km / h 15 km / h. This road sign changing the maximum permissible speed, or a combination thereof, decelerates the vehicles to such a speed that the vehicles located in front of the road safety signal, from the beginning of the hazard warning signal to the opening of the bolts, preferably during the warning signal. , could not enter the crossing before the barrier is triggered, and this is ensured by the fact that the road signs changing the maximum permissible speed are activated at the beginning of the ringing of the railway crossing barrier system or when the crossing warning light is activated. of the railway crossing barrier system, ie when the barrier is lowered.

The distance between the road signs changing the maximum permissible speed as well as the maximum speed they allow is preferably set according to the ringing time until the bolts are released so that vehicles that traveled at the time the road signs changing the maximum permissible speed and traveling at the maximum speed allowed are activated. arrived at the barriers after their launch.

Thus, for example, the first road sign changing the maximum permissible speed, preferably 30 km / h, is preferably located, for example, at a distance of 350 m from the railroad crossing barrier system, to initially slow down the vehicles from the speed they arrive. The second road sign changing the maximum permissible speed for the final deceleration, preferably 15 km / h, is preferably located at a distance of 240 m from the railroad crossing barrier system. The distance of the second maximum speed limit road from the railroad crossing barrier system and the maximum speed limit value of this maximum speed limit road shall be determined by calculation taking into account the time from the start of the warning signal to the barrier opening, which is usually 30s to 45s. the vehicle traveling at this maximum speed limit given by the road sign changing the maximum speed limit reached the gates only after their start and the vehicles traveling at unabated speed arrived at the gates for a sufficiently long time, at least 10s, before starting. she could have run over without any trouble. Thus, for example, the driving time for a vehicle traveling at 50 km / h to travel a distance of 240 m is approximately 17 seconds. A vehicle traveling at this unabated speed would travel this distance from the second traffic sign changing the maximum permissible speed in less than the time from the beginning of the alarm to the opening of the bolts, eg 30s, and if 240 m from the level crossing , it would arrive to it even 13s before their start, ie in case of illegal entry to the crossing would have enough time to safely pass the crossing before rf · * b. 9 9 9 9 9 99

A vehicle traveling at this reduced speed and located at the above-mentioned distance from the level crossing at the time of the start of the alarm would reach the level crossing only after the gates have been lowered.

The system of the signaling device is preferably provided with a traffic sign "Light signals", preferably illuminated by means of LEDs. These "Traffic Signs" traffic signs can be installed more than one in succession, for example two, being located on columns of traffic signs changing the maximum permissible speed. The LEDs of the traffic light "Light signals" are preferably switched on when the crossing warning signal is triggered, and are preferably switched off when the bolts are triggered, i.e. they are preferably activated during the ringing period.

The level crossing device is preferably provided with a switchable traffic sign "End of all prohibitions", preferably light or mechanical with slats, and preferably located on a traffic sign post "Light signals" at a distance of preferably 80 m and 160 m from the railway crossing barrier system . The "End of all prohibitions" traffic sign is activated when the gates are lowered and allows vehicles to reach the lowered gates at a reduced speed.

The level crossing device preferably comprises a voice unit preferably located on a vehicle stop post, i.e. at a distance of about 80 m from the level crossing, and the voice unit preferably reports text such as " Stop here, camera red " . The signaling device system preferably also comprises a second voice unit, preferably located 80 m in front of the first voice unit. Preferably, the voice units are switched off when the vehicle sensor detects that the vehicle has stopped prior to the first command signaling. Preferably, an acoustic sensor is also provided near the level crossing, preferably on the camera mock-up post, which serves to detect the warning ring of the level crossing security device and which preferably comprises a directional microphone. Advantageously, a traffic sign " End of speed measurement " and an omnidirectional transmitter for transmitting a signal for at least one of the traffic signs " Traffic signals " The signal transmitted by the omnidirectional transmitter is received by receivers preferably located on the columns of the above-mentioned elements, the state of which is controlled by this signal. Advantageously, a traffic sign " Speed Measurement "

The level crossing device preferably comprises signaling lights in the roadway to highlight the vehicle stopper until the latch is lowered. Signal lights in the road are in * • ·· '

preferably located in the roadway at the vehicle stopper and activated with it until the barrier is lowered, and are preferably delimited by a " Continuous Continuous "

This design ensures multiple securing of the railway crossing barrier system. Advantageously, the first safety measure consists in decelerating the vehicles with a deceleration section using road signs changing the maximum permissible speed from the beginning of the warning system ringtone to the opening of the barriers so that the vehicles cannot reach the crossing before the barriers are lowered. Preferably, the second safety measure consists in stopping the vehicles by the vehicle stopper until the bolts are lowered. Advantageously, the third safety measure consists in placing a vehicle stopper exceeding the maximum permissible speed.

Preferably, the fourth safety measure consists in highlighting the vehicle stopper for a period of time until the gates are lowered with a light sign preferably bearing the word "STOP" and preferably with a countdown timer. Advantageously, the fifth safety measure consists in highlighting the vehicle stopper until the barrier is triggered by the voice unit. All of the above safety measures are effective separately to ensure crossing safety and optionally applied.

The acoustic sensor detects the acoustic signal of railway crossings. It is preferably provided by means of a directional microphone, preferably located in the focus of the dish directed to the railway signaling device, and the acoustic sensor is preferably tuned. This means that the characteristics of the microphone and its sensitivity in conjunction with the evaluation circuits are set to the characteristic and energetically maximally represented frequencies occurring in the audible warning signal of the level crossing, preferably for each level individually.

This ensures that the detector only responds to this audio signal. Tuning is performed automatically at the instruction of the operator by means of a microprocessor, which in the respective mode of operation evaluates the audible signal of the given railway warning signaling device and sets the characteristics of the evaluation circuits. Sound evaluation is based on Fourier signal development to individual components and their content is compared with the sample to which the acoustic sensor is tuned. When sufficiently matched, the sensor sets its output signal to a state with the meaning that the level crossing warning sound signal has been detected and another signaling according to the present invention is provided providing increased level crossing safety.

Railway audio signals contain at least one, but mostly two dominant frequencies, but there may be more. The audible warning device located on the far side of the passage for the opposite direction also touches the downstream side of the level crossing. This makes it possible to tune the acoustic sensor only to the facing or both sides, which further increases the level crossing safety, since further signaling will occur on both sides even in the event of a failure on the rail equipment on one side.

A directional microphone that senses a railroad audible warning signal at a level crossing is directed to the level crossing and placed in the parabola, and a signal therefrom is applied to an amplifier, preferably differential input, and further converted to a digital signal in the A / D converter. This signal is evaluated in a microprocessor and compared to a recorded sample characteristic of the subject crossing. In the case of a match, the signal at the respective microprocessor output has a value that expresses the match preferably, wherein the microprocessor output signal can have a significance of 1 after deterioration, preferably lasting for an adjustable reception time of the tuned signal after an adjustable time from the beep. This signal is used to activate other devices, either wired or wireless via an omnidirectional transmitter, so that all crossing security devices fitted with the receiver can use the signal.

Alternatively, the transmitter is adapted for duplex communication with a receiver also adapted for duplex operation over a mobile network, preferably a local WIFI network.

These are preferably registered in the memory of the microprocessors and / or preferably sent over the remote network, preferably the mobile operator network to the monitoring center server and from there preferably to the selected subscribers. Preferably, the device comprises security sensors protecting the device from theft from an industrial camera, which are transmitted to a surveillance console, which can preferably address a potential thief at the time of the crime and detach it with a voice unit.

Another advantageous embodiment consists in adding a vehicle stop to the level crossing, which also constitutes a mechanical barrier for the vehicles to enter the level crossing. In order to prevent the bolt from embracing in the opposite direction of the road, preferably the bolt in the opposite direction and / or the barrier between the road directions of the road are also added. The barriers are triggered with an adjustable delay after the level crossing signaling starts and the bar in the opposite direction is triggered optionally along with the bar in the direction, the bar in the opposite direction is fitted with a vehicle sensor in the opposite direction. ··· ·· ··································· · ···· ··· · The barrier is raised to allow this vehicle to pass, then immediately lowered to prevent the vehicle from passing in the opposite direction.

Another advantageous embodiment of a signaling device for stopping vehicles prior to a level crossing with a forward vehicle stop preferably comprising a forward barrier, which preferably starts with an adjustable delay after the light signaling is activated by a receiver which detects a signal from the transmitter signaling of the level crossing system and barriers. Advantageously, the gates are raised after the gates have been lowered or the system alarm has ended. The vehicle stop is preferably a traffic light, which is preferably realized by an alternating flashing traffic light. In order to increase the efficiency of the vehicle stopper with the forward gate, a counter-gate is also preferably installed, which prevents the vehicle from passing by the vehicle in the opposite direction. Preferably, the gates are lowered with an adjustable delay after the start of the traffic light signal activated by the level crossing detector at the start of the level crossing signaling and is preferably raised at the opening of the gates or at the end of the level crossing alarm. The barriers are preferably lowered simultaneously.

The bolt may be partially tilted, preferably by an angle of 45 ° in the case, especially when mechanical barriers are not used, to prevent accidents of vehicles mainly from the opposite direction that illegally overtakes. The LED strips located on the barrier arm preferably signal in advance of vehicles arriving in the opposite direction by the flashing light of the lowering and / or lifting of the barrier and preferably by the constant light of the barrier at rest in the lowered and / or raised position, preferably red light.

The route of the signaling device for stopping the vehicles before the level crossing can be supplemented by a deceleration section, preferably with a road sign changing the maximum permissible speed. Further, the route comprises two forward vehicle stoppers, preferably a level crossing detection unit, a red-light detector, a barrier separating road sections used in one and the other direction, and a mechanical barrier.

The second advance stopper, which is preferably located downstream of the first stopper, is preferably formed by a forward pushbutton and / or a light semaphore, which is formed by at least one of: an alternately flashing traffic light, a tricolor traffic light, a two-color traffic light. Advantageously, a forward road sign changing the maximum permissible speed is placed in front of the first stop, the vehicle decelerating to a speed such that it can safely stop in front of the second stop.

Advantageously, a second road sign changing the maximum permissible speed, or a combination of, for example, two road signs changing the maximum permissible speed of 30 km / h and 15 km / h, located one behind the first stop, ensures deceleration of vehicles to such a speed second stopper. Alternatively, when using only one stopper (the first not applied), a road sign changing the maximum permissible speed (shown in dashed lines in FIG. 10) is preferably placed in front of the second stopper. Preferably, the traffic speed varying signs are activated simultaneously with the stoppers, i.e. at the beginning of the railroad crossing barrier warning system, and preferably turn off when the railroad barrier crossing barrier warning system has ended, or at a barrier crossing when a barrier is triggered.

···· · · · · · · · · · ·

The distance between the road signs changing the maximum permissible speed as well as the maximum speed they allow is preferably set according to the ringing time until the bolts are released so that vehicles that traveled at the time the road signs changing the maximum permissible speed and traveling at the maximum speed allowed are activated. arrived at the latches or forward latches, if they are applied, only after their launch.

Preferably, the first forward stop and the first road sign changing the maximum permissible speed are activated at the start of the level crossing alarm. Preferably, the second advance vehicle stop is activated simultaneously with the first stop and thus in advance of eventual triggering of the barrier advanced in the event of the vehicle passing to the red first stop so that the vehicle can safely stop before it is started. Alternatively, the forward gate is triggered with a delay after activation of the stoppers and the traffic sign changing the maximum permissible speed.

Said signaling devices for stopping vehicles before a level crossing are for a level crossing system with or without bolts.

The invention also encompasses a safe design of the forward bar allowing it to rotate in the direction of travel of vehicles in the event of an impact into the forward bar.

The forward bolt is located on the bolt stand and can rotate horizontally, preferably on the pivot joint. In the event of an impact, such as an approaching vehicle, into the forward barrier, the barrier is swiveled in the direction of travel of the vehicle. The returning of the bolt advanced to the initial position is preferably provided by a bolt mechanism which preferably comprises a spring that is tensioned when the bolt is rotated and returns the bolt to the initial position. Securing the end position when the bolt is rotated, for example for the safety of pedestrians passing along the road, preferably at an angle of 90 ° from the starting position, which corresponds to a direction parallel to the road, is provided by the bolt stop. Lifting of the bolt is ensured by motor on the bolt lifting joint.

It is advantageous to provide a safe design of the forward barrier allowing it to rotate in the direction of the approaching vehicles in the event of an impact into the forward barrier. This advantageous embodiment is a version with a pivotable head of the bolt that is located on the bolt stand, holds the bolt forward and can rotate with it. In this case, the return of the bolt to the initial position is preferably provided by an electric motor. Lifting of the bolt is ensured by motor on the bolt lifting joint.

Securing the end position when the bolt is rotated, for example for the safety of pedestrians passing along the road, preferably at an angle of 90 ° from the starting position, is provided by the bolt stop.

It is also advantageous to provide a safe design of the forward barrier allowing it to rotate in the direction of the approaching vehicles in the event of an impact into the forward barrier. This reduces the impact of the vehicle or other object into the forward gate. The forward bolt is located on a bolt stand that can be rotated, preferably on a bolt of bolt rotation of the bolt stand, which is a steep pitch threaded rod anchored to or near the roadway. This steep pitch of the bolt of the bolt of the bolt stand ensures that the bolt is returned to its initial position by gravity. In the event of an impact, for example of an approaching vehicle, into a forward gate, the latter is turned in the direction of the approaching vehicle. In this case, the latch stop, preferably with the barrier stop damper and preferably with by locking the latch arm.

It is advantageous to provide a safe design of the forward barrier allowing it to rotate in the direction of travel of the vehicles and at the same time in the upward direction in the event of an impact into the forward barrier. This reduces the impact of the vehicle or other object into the forward gate.

The forward barrier is located on a supporting, vertically anchored, dome-shaped rack, which contains mechanical and electronic equipment for its control. The bolt stand is provided with a bolt arm guide hole, which has the shape of a part of the helix and allows it to be swiveled in the event of an impact, for example of an approaching vehicle in the direction of travel of the vehicle and simultaneously in the upward direction. The return of the barrier downwards to its original position occurs spontaneously due to the gravitational force given by the weight of the barrier. In this case, the latch stop, preferably with the barrier stop damper and preferably with by locking the latch arm. In case of a weaker impact of the vehicle into the barrier arm, where the complete opening of the barrier arm to the vertical position would not be guaranteed, the electromechanical drive is activated by a shock or position sensor with adjustable sensitivity located in the barrier. The electromechanical drive then ensures the barrier to run over the entire length of the guide hole to the open vertical position of 90 ° following the "Z" axis. Retracting the basic arm of the bolt • · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · «« ··· · ·· ···· ··· · Electromechanical actuator located in the bolt stand, switched locally, remotely or timing relay, is in position again.

The standard lift, i.e. not in the event of an impact, of the upward bolt 330 is provided by an electromechanical drive. Opening and back closing of the bolt arm 65 is provided by an electromechanical drive located in the bolt rack 46, switched locally, remotely, sensors or timing relay.

Also advantageous is an embodiment where the bolt forward may be rotated on the bolt of the bolt stand rotation and at the same time on the bolt rotation joint with the bolt arm movement through the bolt arm guide hole.

It is advantageous to combine a pivot bracket with a guide bar which, when the vehicle strikes the forward bar, allows the bolt to bend in the direction of travel of the vehicle and at the same time upwards. The bolt stand is rotatable horizontally on a bolt rotation bolt of the bolt stand mounted vertically on the base of the bolt stand mounted on the ground, for example on a pavement according to which the bolt stand rotates.

The lowered bar rests on the bottom part of the bar, preferably in the V-shape, which guarantees the position of the bar. The pressure of the vehicle striking the bolt moves the bolt horizontally in the direction of travel, the bolt being guided upwards by the bolt arm guide bar.

The bar of the bar is fixed to the base of the bar by fastening posts.

The movement of the bolt along the bolt arm guide is preferably defined by the bolt stop with the bolt stop damper against the bolt arm guide bar impact.

The internal mechanism of the bolt stand is designed such that the bolt arm is rotatable vertically on the bolt bearing attracted to the shorter bolt arm by a pulling element, preferably a disc-shaped element, preferably a gear driven by an electric motor. This raises the longer boom arm. The bolt stand mechanism allows the bolt to be lifted even by the pressure of a moving vehicle when the pulling element is released.

If there is a bend in the immediate vicinity of the crossing, which prevents the driver from directly seeing the crossing warning signal, it is advantageous to apply an embodiment of the forward signaling device for stopping the vehicles before crossing the railway crossing. A barrier preventing the driver from seeing a level crossing warning signal may consist, for example, of trees at the level crossing. In this case, a stop is installed in front of the bend, preferably consisting of a stopper, preferably consisting of a stopper. 9 traffic lights that signal the red signal light in the same way as the level warning and allow the driver to see its status. Advantageously, at the location of the stopper (second) there is also a forward gate. Advantageously, an additional traffic light is placed in front of the bend, ahead of the traffic light before the bend, preventing vehicles from crossing over at the time of the warning signal, which is preferably active only at the barrier crossing until the barrier is triggered.

Advantageously, also a forward road sign changing the maximum permissible speed is used, which slows the vehicle so that it can safely stop in front of the first stop or the second stop.

In the case where there is an intersection on the access road in the immediate vicinity of the crossing, it is advantageous to use an advance signaling device for stopping vehicles, where the intersection is controlled by traffic lights, preferably tricolor traffic lights, either only at the time of crossing warning or continuously. This is done at a barrier crossing so that vehicles are prevented from crossing the crossing either during the entire alarm period or preferably until the barrier is lowered. At a crossing without barriers, the junction is controlled in such a way as to prevent vehicles from crossing the crossing at all times. If there are multiple lanes at the intersection, then the junction is controlled so that the vehicles in the lane heading for the crossing are stopped by traffic lights, preferably tricolour traffic lights, at the time of the crossing warning and cannot arrive at the crossing lanes that do not lead to a level crossing have not been stopped in this way and could continue driving in a direction outside the level crossing.

Advantageously, the forward signaling device for stopping vehicles before a railway crossing comprises a mechanical barrier preventing the vehicle from crossing the lane in the opposite direction and preventing accidents of vehicles mainly from the opposite direction which illegally overtake the lane in the opposite direction with vehicles traveling in the opposite direction. The mechanical barrier may be formed by cones or cylinders, or by an island, or crash barriers, or by a projection above the center line. It is preferred that the mechanical barrier be formed by cylindrical bolts, preferably of elastic shape memory material, preferably of rubber or plastic, which allows it to return to its original shape after deformation caused by a load, for example by a vehicle passing over it. The mechanical restraint is at the base of the mechanical restraint to which it is attached by means of a mechanical restraining element, preferably constituted by a spring or a rod. • Elastic material. • • • • • • • • • • • • • • • Preferably, the base of the mechanical barrier is provided with mechanical barrier stops which prevent it from undesirable movement, for example by the influence of wind.

The mechanical barrier is anchored to the substrate, usually to the road, preferably by means of screws or screws.

For example, if the vehicle is driven by a mechanical barrier to prevent it from moving onto the opposite lane, it may cause it to tilt. In this case the spring of the mechanical barrier is stretched and returns to its original position after releasing the pressure that tilted the mechanical barrier.

For example, if a vehicle is placed on a mechanical restraint to prevent it from approaching the opposite lane, it may cause it to tilt with simultaneous deformation of the mechanical restraint. The design of the mechanical barrier of elastic shape memory material allows it to return to its original shape after releasing the pressure that has distorted the mechanical barrier, such as the weight of the vehicle that has passed over it.

A single-color traffic light 15 signals a red light, a two-color traffic light turns orange light to a red light. Preferably, the signaling signal 3 is exchanged for a traffic light 103. The communication unit 7 preferably sends an alarm and preferably camera shots 10 to the fire brigade 16, the police 17, the emergency control room 18 so that they can prepare to exit in the event of a collision in space in system 1 latches.

The camera 10 transmits to the police all necessary data, for example a vehicle registration number, for eventual sanction of a party, for example a driver of a vehicle 5, which caused an obstacle 9 to be placed on the track. In the event that the obstacle 9 is a vehicle 5 that leaves the barrier area without an accident, the police 17 is preferably equipped with a road display controller 19 instructing the vehicle 5 to wait for the shelf to arrive, e.g. Advantageously, the communication unit 2 sends data to a server 21 to which selected participants 22 have access, for example a train control station 11, preferably via the Internet, and / or a train set 12,

The selected participants have access to the situation data of all barrier systems 1, which are equipped with a communication unit 7 and respective units 221 for sensing and / or detecting an obstacle, preferably by sensors 4 and / or cameras 10.

The communication unit 7 is adaptable for direct connection with elected participants 22.

Giant. 3 illustrates a level crossing device with a bolt system 1 in which the right-hand space 35 is detected by the right-hand sensor system 48. In the event that this sensor system detects an obstacle 41 on the right, it prevents the right-hand barrier 60 from lowering behind the rails. In case it is already partially or fully lowered, the control unit 6 shown in FIG. 1 will lift it and allow it to lower only when the obstacle 41 is not detected by the sensor system 48. The position of the latches "left" "right" is viewed The "forward tracks" and "behind tracks" positions are taken from the driver's point of view in the direction of his arrival at the level crossing. Similarly, the left sensor system 54 operates left for the room 42 with sensors 44, 45, 55 and 56 detecting the obstacle 59 left. The latch system 1 comprises a latch 60 right behind the rails, a latch 61 left before the rails, a latch 62 right before the rails and a latch 63 left behind the rails which are controlled by the control unit 6 and in case the sensor systems 48 and 54 do not detect obstacle 59, 41 , all bolts 60, 61, 62, 63 are triggered simultaneously or the bolts behind the rails 60, 63 are delayed.

In case there is no match in the detection of all sensors, the barrier system 1 will trigger an alarm in the train control center 11 via the wireless communication 13 to correct the fault as shown in Fig. 1.

Similarly, the left sensor system 54 operates.

Giant. 4 and its detail 1 show a signaling device 125 for stopping vehicles before a railway crossing, preferably consisting of a traffic light 103, located at an optional distance, e.g. 50 m, from the barriers 2.

Preferably, the traffic light 103 is a tricolor traffic light 204 or a two-color traffic light 205 or a light signal 206 of two side-by-side alternating flashing lights.

The traffic light 103 located at an optional distance in front of the latches 2 with a "STOP" signal stops the vehicles arriving at the latches 2 ahead of them at the time of the warning lights 106 crossing before the latches 2 are triggered. she couldn't enter the level crossing. Then the control unit 6 switches the signaling to "LEAVE". The vehicles can continue to travel to the latches already in place to prevent them from entering the crossing.

Thus, the level crossing detecting unit 73 detects the start of the signaling of the warning lights 106, preferably by a light sensor 107, preferably formed by an optical sensor 211, or a camera sensor 212 and triggering the bolts 2 by a sensor 121 to detect triggered beams or both. the unit 73 detects the alarm ring preferably by an acoustic sensor 213. or is preferably connected via a bolt wire link 124 via an optical coupler 123 to the bolt system 1.

The activation of the "crossing warning lights 106", eg by alternating flashing of two red lights, is detected by this detection unit 73, which is used in the event that a direct electrical connection of the connection 105 to the railroad warning device 106 is not possible or desirable. 108 is connected directly to the level crossing electrical signaling device for alarm and ring information. In the case of using this detection unit 73, preferably constituted by an optical sensor 211, the unit is for transmitting the warning light activation information.

connected to the control unit 108 of the signaling device by a link 105, which is optionally implemented by conductors and / or wirelessly. This transmits the warning light activation signal 106 to the control unit 108, which sets the signaling to "STOP", preferably by the red light of the traffic light 103, preferably consisting of a tricolor traffic light 204. 121, detecting the lowered gates, the control unit 108, which sets the semaphore 204 back to "LEAVE", preferably with a green light, which preferably follows the orange light. If the traffic light 103 is formed by a two-color traffic light 205, it lights up with a red signal light when it is switched to "STOP". When it is set to "LEAVE" it flashes with an orange signal light or does not indicate. If this traffic light 103 is formed by a light signal 206, it flashes alternately with red lights placed next to each other when it is switched to "STOP" and it is switched off when it is switched to "LEFT".

The level crossing detection unit 73 is preferably formed by an optical sensor 211 and / or an acoustic sensor 213 and / or a camera sensor 212 and / or a detector detecting sensor 121. At the beginning of the ring, the traffic light 103 is set to "STOP", at the end of the ring to "LEAVE".

The warning light sensors 107, 211 optical and 213 acoustic, are preferably located directly on the barrier rail device or on a separate forward sensor column 214.

Preferably, the maximum distance 109 of the traffic light 103 from the barriers 2 is selected such that vehicles at the highest permitted speed, for example 50 km / h, travel this distance with a margin so as to arrive at the barriers 2 preferably just after the warning lights 106 start flashing. the gates 2 are still at the top, so that, in the event that vehicle drivers fail to comply with the traffic rules and enter the level crossing despite the activation of the hazard warning lights 106, they have sufficient time to safely and safely pass the crossing before the gates. The distance 109 is preferably determined according to the time preceded by the warning signal before the bolts 2 are triggered, which starts approximately 30 seconds after the flashing of the warning lights 106 has started. Just before the gates 2 are triggered, no more cars will pass through the gates, as they are stopped by the traffic light 103 in advance.

After the bolts 2 have been lowered, the control unit 108 will set the traffic light 103 to "LEAVE", but the vehicles, if initially stopped, can now arrive at the latches 2 already triggered. The next cycle of resetting semaphore 103 to "STOP" is initiated the next time the hazard warning lights 106 or ringer are activated.

• · · · · * * * * *

Optionally, the traffic light 103 is set to "OFF" only when the warning lights 106 flash, i.e., after the gates have been lifted and not when the gates have been lowered. This signaling device is also applicable to unprotected crossings where the gates are not installed.

Giant. 5 shows a signaling device 125 for stopping vehicles before a railway crossing completed by a deceleration section 118, by means of which the deceleration is realized by visualizing the activated traffic light 110 when the warning lights 106 detected by the warning light sensor 107 are activated. 122, which slows the vehicle, but also the radar unit 116, preferably the flashing display 119 of the radar unit 23 turning green to red in front of the traffic sign 110 located when it registers that the vehicle exceeds the maximum permissible speed displayed thereon, speed is adjustable.

Optionally, the combined deceleration section 122 can be fitted multiple times to increase the effect. It can be used in road traffic at crossings with or without barriers. In this case, the traffic light 110 is activated only from the radar unit 116, which can be placed in the traffic light 110, too.

The deceleration section 118 or the combined deceleration section 122 is preferably followed by a stop section 115 whose radar unit 116 converts the light semaphore 103 to "STOP", preferably red, by the control unit 108, while the vehicle arrives at a speed exceeding the currently valid maximum permissible speed even though the crossing warning lights 106 are not activated to slow down the vehicle. When they are activated, they are reset to "STOP" for as long as they are activated, preferably until the gate is lowered.

The radar unit is preferably adapted to be set to either a speed not reduced, for example 50 km / h, or reduced, for example 30 km / h, when a level crossing warning is detected and the traffic sign 110 is activated.

Giant. 6 illustrates another example of a vehicle stop signaling device 125 prior to a level crossing comprising two stoppers 83 in the event that a driver has illegally passed a first stopper 83 preferably comprised of a red light semaphore 103 and is detected by a red light detector 136 preferably formed by a camera 226; a lane-edge sensor 134 that activates the second stop 83, preferably comprising a "No Entry All Traffic" light sign 131 and / or a "Commanded Direction" traffic sign, which will lead the driver to the lane 20 where the driver preferably see sign 135 waiting for the police to wait.

Preferably, the communication unit 139 is adapted for voice communication with the supervisor and / or the police. The advantage of the lane 133 with the barrier 130 in front of the barrier 130 'on the road is that it is possible to keep stopped vehicles that have gone red, preferably until the police arrive or for an adjustable time without affecting traffic on the road after lifting the barrier 2 .

Giant. 7 illustrates an example of a device for securing a level crossing against flashing warning lights by means of traffic lights located at the junction and junction 70 of the "T" type.

The traffic lights control intersections 69 in a conventional manner by means of a control unit 6 to which they are connected by means of connections 105. When the signal 206 is activated two side by side intermittent

The traffic lights 15, which control the lanes “A”, from which the access to the barriers 2, are switched to the “STOP” mode, in which it lights red and if it lights in a different color, it changes to red in a prescribed manner, over orange. This will prevent lanes from crossing lanes “A” to barriers 2. The lanes of traffic lanes “B” leading from barriers will turn green so that vehicles can leave and no traffic lanes can form.

The activation of the light signal 206 is preferably detected by a warning light sensor 107 which is connected to the control unit 6 by a connection 105.

The traffic lights are switched from "STOP" mode to the conventional junction control mode when the barrier is triggered, preferably upon detection by the barrier detecting sensor 121 and / or the warning light sensor 107 signaling the end of light activation, the information being transmitted over the link 105.

Vehicle sensors 71 detect vehicles traveling in lane "B" from the gates and, in the case of a detected vehicle, switch the junction control so that these vehicles preferably have a green light in order to avoid the formation of traffic obstruction.

The vehicles are stopped in the "STOP" mode only for the time the signal 206 is activated, until the gates close, ie for a relatively short time, about 20 seconds.

Then the junction control switches to normal operation and the vehicles pass the controlled junction already to the latches 2 so that they cannot pass over when the hazard warning lights flash.

Vehicles moving between intersections and crossings at the time of signal 206 and "STOP" activation arrive at the very beginning of the hazard warning lights, so if they fail to do so, they have about 20 seconds for a relatively safe barrier crossing before they start. . Other vehicles that would be risky to cross are already detained by traffic lights 15.

Or the traffic lights 15, at the time of the lift gate 2, do not drive the intersection, the traffic lights are off or flash orange. The 'B' directional traffic light is preferably not installed and the vehicles in this lane are constantly clear of traffic.

If the signal 206 is activated, the color of the lights will change from orange flashing to red in a preset manner until the bolts are triggered, turning back to flashing orange.

Advantageously, a deceleration section 118 is provided upstream of the vehicle stopper 83 until the barrier is triggered, provided with preferably a maximum speed limit road sign 155 or a plurality of maximum speed limit signs 155, preferably two, for example, 30 km / h and 15 km / h.

The second road sign 155 changing the maximum permissible speed for the final deceleration, preferably 15 km / h, is preferably located at a distance of 240 m from the railroad crossing barrier system 1. The distance of the second maximum speed limit road 155 from the railroad crossing barrier system 1 and the maximum speed limit value of this maximum speed limit road 155 is determined by calculation with respect to the time from the start of the alert ring to the barrier start, which is usually 30s to 45s. so that the vehicle traveling at this maximum speed limit given by the 155 maximum speed limit road will arrive at the bolts only after they have been started, and the vehicles traveling at unabated speed will arrive at the bolts sufficiently long, at least 10s, before starting. it could still run over without warning. Thus, for example, the driving time for a vehicle traveling at 50 km / h to travel a distance of 240 m is approximately 17 seconds. A vehicle traveling at this non-reduced speed would travel this distance from the second maximum speed warning sign 155 in less than the time from the start of the alarm to the opening of the bolts 2, for example 30s and if it were 240 m from the alarm. railway crossing, it would come to him even 13s before their start, so in the case of illegal entry to the crossing would have enough time to safely pass the crossing before starting the race. On the other hand, the travel time for a vehicle traveling at a reduced speed of 15 km / h to travel a distance of 240 m is approximately 58s. A vehicle traveling at this reduced speed and located at the above distance from the level crossing at the time of the alarm signaling would reach the level crossing only after the gates 2 have been lowered.

When sufficiently matched, the sensor sets its output signal to a state with the meaning that the level crossing warning sound signal has been detected and another signaling according to the present invention is provided providing increased level crossing safety.

Railway audio signals contain at least one, but mostly two dominant frequencies, but there may be more.

Giant. 15 illustrates an embodiment of a forward signaling device 125 for stopping vehicles prior to a level crossing when there is a bend in the immediate vicinity of the level crossing which: 4 4 4 4 4 4 4444444 Prevents drivers from looking directly at the crossing warning signal. A barrier preventing the driver from seeing the level crossing warning is illustrated by the trees at the level crossing in Fig. 12. In this case, a stopper 83, preferably consisting of a traffic light 103, is installed upstream of the bend, which signals the red signal light in accordance with the level crossing warning and allows the driver to see its status. Advantageously, at the location of the stopper 83 (second), a latch 330 is also advanced. Advantageously, an additional traffic light 103 is placed in front of the bend, before this traffic light 103 before the bend, preventing vehicles from crossing over at the time of the warning signal, which is advantageously active only at the barrier crossing until a barrier is triggered. . Advantageously, also a forward road sign 155 is used, varying the maximum permissible speed, which slows the vehicle so that it can safely stop in front of the stop 83 first or the stop 83 second.

Giant. 16 illustrates an embodiment of a forward signaling device 125 for stopping vehicles in the case of an intersection on the access road in the immediate vicinity of the crossing. This intersection is controlled by traffic lights 103, preferably tricolor traffic lights 204, either only at the time of crossing warning or continuously. This is done at a crossing with barriers 2 so that vehicles are prevented from entering the crossing during either the entire alarm period or preferably until the barriers are lowered. At a crossing without barriers, the junction is controlled in such a way as to prevent vehicles from crossing the crossing at all times. If there are multiple lanes at the intersection, then the junction is controlled so that vehicles traveling in the lane leading to the level crossing are stopped by traffic lights 103, preferably tricolor traffic lights 204 at the time of the level crossing warning, and cannot reach the level crossing driving in lanes that do not lead to a level crossing was not so stopped and could continue to run in the direction outside the level crossing.

Giant. 17 illustrates an embodiment of a mechanical barrier 126 to prevent a traffic lane in the opposite direction, which is part of a forward signaling device 125 for stopping vehicles before a railway crossing and serves to prevent vehicle accidents mainly from the opposite direction . The mechanical barrier 126 may be formed by cones or cylinders, or by an island or by crash barriers, or by a projection above the center line. In the embodiment of FIG. 17, the mechanical barrier 126 is formed by a foot of cylindrical shape, preferably of an elastic material with a

Memory, preferably made of rubber or plastic, which allows it to return to its original shape after deformation caused by a load, such as a vehicle that has passed over it. . The mechanical barrier 126 stands on the base of the mechanical barrier to which it is attached by means of a mechanical barrier spring 102, preferably formed by a spring or a rod of elastic material. Advantageously, the mechanical barrier base 101 is provided with mechanical barrier stops 103 which prevent it from undesirable movement, for example by wind. The mechanical barrier 126 is anchored to the substrate, usually to the road, preferably by means of screws.

Det. 1 FIG. 17 illustrates the inclination of the mechanical barrier 126 to prevent it from sliding into the opposite lane, caused, for example, by the pressure of the vehicle that has driven the barrier. In this case, the spring stop 102 of the mechanical barrier is stretched and returns to its original position after releasing the pressure that tilted the mechanical barrier 126.

Det. FIG. 17 illustrates the inclination of the mechanical barrier 126 to prevent it from moving to the opposite lane, caused, for example, by the pressure of the vehicle that has driven the barrier with the simultaneous deformation of the mechanical barrier 126, which may be caused for example by the wheel weight of the vehicle. The design of the mechanical barrier 126 of elastic shape memory material allows it to return to its original shape after releasing the pressure that deformed the mechanical barrier 126, for example the weight of the vehicle that has passed over it.
