Description

Technical field

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 the gates are lowered simultaneously, so that the vehicle which enters the track when the gates are lowered and thus is in the track, its exit being blocked by the gate behind the track which has meanwhile been lowered so that it cannot exit the track. 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 •

preferably, in the train control station arriving at the train set and at other selected participants via wireless communication, preferably the communication unit sends alarm and / or camera images directly to the train set via a wireless link. 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 fire-fighters, the police, the emergency control center, so that they can prepare to exit in the event of a collision in the space 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 left space

· • ·

• · 9 • · sensor system left with sensors and detecting the obstacle on the 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 device unit by means of a link which is optionally implemented by conductors and / 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 bolts are started 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 radar unit display in front of traffic light ·

· •

»| In addition to the actual measured speed, the sign preferably also displays a slow to a certain speed, for example 30 km / h, referring to the speed indicated on the traffic light 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 to passageways when the hazard warning lights flash with the help of traffic lights located at the intersection and intersection. 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 running between intersections and crossings at the time of signal activation and "STOP" mode arrive at the very beginning of the hazard warning lights, so if they do not 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. The 'B' directional traffic light is preferably not installed and the vehicles in this lane are constantly clear of traffic.

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 having a traffic sign changing the maximum permissible speed or more, traffic signs changing the maximum permissible speed, preferably two, for example 30 km / h and 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, so in case of illegal entry to the crossing would have enough time to safely pass the crossing

On the other hand, the driving 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-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. Preferably, 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. The signaling lights in the roadway are preferably located in the roadway at the vehicle stop and are activated with it for the period until the bolts are lowered, and are preferably enclosed by a traffic sign "Continuous continuous" usable for highlighting the stopping point vehicles on activation.

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. This allows you to collect device status information from status detectors. 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 has begun 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 bolt is raised to allow the vehicle to pass, then immediately lowered to prevent the vehicle from passing in the opposite direction.

After an adjustable time, the barriers 2p in front of the rails and 2z behind the rails start to be triggered simultaneously or the barriers behind the rails are lowered after an adjustable time, preferably the expected time required to leave the track by the vehicle.

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,

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.

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 by the "STOP" signal stops vehicles arriving at the latches 2 ahead of them, at the time of the warning lights 106 crossing before the latches 2 are triggered. the vehicles could not 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 a light sensor 107, preferably formed by an optical sensor 211. or a camera sensor 212 and triggering the barriers 2 by a sensor 121 to detect triggered barriers 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 L

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. When using this detection unit 73, preferably consisting of an optical sensor 211, the warning light activation information transmission unit is connected to the control unit 108 of the signaling device via a link 105, which is optionally implemented by conductors and / or wirelessly. This will transmit a warning light activation signal.

106 to the control unit 108, which switches the signaling to "STOP", preferably by red light of the traffic light 103, preferably consisting of a tricolor traffic light 204. Barrier triggering information 2 is transmitted by the detection unit 73, preferably formed by the light barrier detection sensor 121. 108, which sets the traffic light 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 already released.

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.

Advantageously, a deceleration section 118 is provided in front of the traffic light 103 with a traffic sign 110 " Maximum permitted speed ", for example 30 km / h. Advantageously downstream of the deceleration section is a traffic sign 120 " End of all prohibitions ", preferably a traffic light which terminates the speed limit. This sign is preferably activated depending on the activation of the "Maximum speed limit" traffic signs 110, preferably activated together with the crossing warning lights 106 or the traffic light 103. The traffic signs 110 are located on a separate post 112 or a traffic post 113 Marking 102 "Crossing with barriers".

The barrier crossing section 118 with barriers is preferably implemented to slow down the traffic of vehicles prior to the activated barriers 2. The crossing warning lights 106 are activated and begin to signal, preferably by blinking, the onset of the barriers and simultaneously selectable number of traffic signs 110 “That lights up and displays an adjustable speed, such as 30 km / h. They are optionally deactivated when the bolts_2 are triggered or the hazard warning lights 106 are deactivated.

To accentuate the impending lowering of the barriers 2, the "barrier crossing" traffic signs 102 are preferably illuminated and / or are preferably provided with orange signal lights 111, and, preferably alternately flashing, simultaneously with the warning lights 106, indicate the upcoming lowering of the barriers.

The pre-crossing signaling device is preferably also used for crossings without barriers to prevent access to the level crossing at the time of arrival and crossing of the train, which is signaled by the control room control unit 108, which controls the signaling devices for stopping and decelerating the vehicles.

Optionally, the traffic light 103 is preferably formed by two red lights of the signal 206 of two side-by-side alternating flashing lights, which are activated for the "STOP" signal and switched off for the "OFF" signal.

Preferably, the semaphore 103 has a countdown timer 200 and a light sign 201 highlighting the semaphore with inscriptions and / or symbols, for example, "STOP, 20s" as the countdown timer countdown 200, and "CAMERA ATTENTION RED", s. information to the driver, the inscription being preferably activated when the hazard warning lights are activated.

Preferably, a dummy of camera 117 is installed in the route, by means of which greater driver discipline is achieved. This camera can be replaced by a real camera.

Giant. 4 det 2 shows a simplified variant of the signaling device 125 for stopping vehicles before a railway crossing, where the deceleration section 118 is omitted.

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 a 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 only activated from the radar unit 116, which is locatable in the traffic light 110.

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. Advantageously, a traffic light sign 120 "End of all prohibitions" is activated behind the traffic light 103 when the barrier warning is not detected. Advantageously, there is a vehicle speed sensor 117 which is preferably interchangeable with a real camera, so that there is an optional saving compared to the case where a real camera is fitted, since the control does not know when each camera is deployed. For greater effect, when the vehicle is passing, the light on the camera dummy 117 flashes to make it appear to be recording. In the case of activation of the hazard warning lights 106, the traffic light 120 is not activated in order to maintain a valid speed reduction, for example 30 km / h.

The camera dummy 117 is preferably also positioned on the traffic light 103, preferably on the traffic sign post. Advantageously, there are signs indicating speed measurement in front of the dummies.

to increase the efficiency of mockups. On the radar unit display 119, in addition to the instantaneous measured velocity, the word slow is preferably displayed.

The camera 117 ', replaceable by the dummy 117, preferably captures not only the excessive speed of the vehicle but also the non-stopping of the red traffic light 103.

Giant. 6 illustrates another example of a signaling device 125 for stopping vehicles before a railway crossing when the driver has passed the red light of traffic light 103 and has been intercepted. A red light pass detector 136 preferably comprising a camera 226 or a lane edge sensor 134 which preferably activates the "No Entry All Traffic" light signal and / or the "Commanded Direction" traffic light signal 132 to guide the driver to a park lane 133, where the driver preferably sees the police wait sign 135 and is prevented from exit by a barrier 130, preferably remotely controlled, which is preferably triggered by the detector 136 when passing through the red. 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 Preferably, the barrier 130 'is located on the roadway and is triggered upon detection of a level crossing warning signal or only when the vehicle passes red. In this case, the lane, no entry and traffic sign 132 are not required.

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 the control unit 6 to which they are connected by means of the connections 105. When the signal 206 of two side-by-side alternating intermittent traffic lights 15 are activated. they switch to the "STOP" mode, in which they are lit red, and if they are lit with a different color, they change to red in the prescribed manner, ie from green to 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 barriers 2, and, in the case of a detected vehicle, switch the junction control so that these vehicles preferably have a green light so as not to form traffic-blocking columns.

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.

Giant. 8 illustrates a preferred embodiment of a level crossing signaling device with a signaling device for stopping vehicles before a level crossing with increased safety, which is achieved by combining the vehicle stopper 83 during the alarm, preferably until the bolts are triggered, and preferably with the deceleration section 118 using traffic signs The maximum permissible speed changes 155 and preferably using the voice unit 24 The maximum permissible speed signals 155 are preferably illuminated by a set of LEDs or in a mechanical design, preferably with flip-flops.

The vehicle stopper 83 is preferably constituted by a signaling signal 323 consisting of a tricolor traffic light 204 or an alternately flashing traffic light 34, which is activated at the time of the alarm of the vehicle crossing safety device and preferably deactivated when the barrier 2 is triggered. traffic lights

activated for the duration of the alarm ring. Preferably, a vehicle recording camera 226 that has traveled to red is disposed on the vehicle stop post 83.

The retarder 84 of vehicles exceeding the maximum permissible speed is preferably a tricolor traffic light 204 and is activated for as long as the vehicle exceeds the maximum permissible speed given by the traffic sign 155 changing the maximum permissible speed or, in the absence of activation, previous road sign. The retarder 84 is preferably also activated at the level crossing warning and preferably deactivated when the gates 2 are triggered.

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. This road sign 155, or a combination thereof, provides a deceleration of the vehicle to a speed such that the vehicles located from the start of the hazard warning light 106 to the opening of the bolts, preferably during the warning signal of the crossing security device, the road sign 155 could not enter the level crossing before the gates 2 were triggered, and this is ensured by traffic signs 155 changing the maximum permissible speed preferably activated at the beginning of the ringing system of the railway crossing barrier 1 or at the time of the level crossing warning light 106. advantageously, at the end of the ringing of the rail system 1, the barrier of the railway crossing is switched off, that is to say when the barrier 2 is lowered.

Preferably, the distance of the maximum speed allowed traffic signs 155 as well as the maximum speed they allow is adjusted according to the ringing time until the bolts are triggered so that vehicles that traveled at the time of activation of the maximum speed allowed traffic speed 155 permits, arrived at the barriers after their launch.

Thus, for example, the first traffic sign 155 changing the maximum permissible speed, preferably 30 km / h, is preferably located, for example, at a distance of 350 m from the railway crossing barrier system 1, to initially slow down the vehicles from the speed they arrive. 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 permitted traffic sign 155 from the railroad system i the level crossing barrier and the maximum permissible speed value of this maximum speed permitted traffic sign 155 is determined by calculation with respect to the time from the start of the warning so that the vehicle traveling at this maximum speed limit given by the 155 maximum speed limit road does not reach the gates until they are started and the vehicles traveling at unabated speed reaches the gates sufficiently longer, at least 50 seconds, 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.

The level crossing device is preferably provided with a traffic sign 85 " Light signals ", preferably illuminated by LEDs. Of these traffic signs 85, "Light signals" can be installed more in succession, for example two, being located on columns of traffic signs 155 changing the maximum permissible speed. Traffic light LEDs 85 "Light signals" are preferably switched on when the crossing warning signal is triggered and are preferably switched off when the bolts 2 are triggered, i.e. they are preferably activated for the ringing time.

The level crossing device is preferably provided with a switchable light traffic sign 120 "End of all prohibitions" preferably light or mechanical with slats and preferably located on the post of traffic light 85 "Light signals" at a distance of preferably 80 m and 160 m from the rail system 1 crossing barrier. The "End of all prohibitions" traffic light 120 is activated when the gates are lowered and allows vehicles to reach the lowered gates at a reduced speed.

Preferably, the level crossing device comprises a voice unit 24, preferably located on a vehicle stopper post 83, i.e. at a distance of about 80 m from the level crossing, and the voice unit 24 preferably reports text such as " Stop here " · · · ··

• 27 camera on red ”. Preferably, the signaling device system also comprises a second voice unit 24 positioned preferably 80 m in front of the first voice unit 24. The voice units 24 preferably turn off when the vehicle sensor 71 detects that the vehicle has stopped before the first command signaling 323,

Preferably, an acoustic sensor 213 is also provided near the level crossing, preferably on the camera mock-up column 117, which serves for detecting the alarm signal of the level crossing security device, and preferably comprises a directional microphone 74. and the omnidirectional transmitter 79 for transmitting a signal for at least one of the signs: traffic sign 85 " Light signals " The signal emitted by the omnidirectional transmitter 79 is received by receivers 80 preferably located on the columns of the above-mentioned elements whose state is controlled by this signal. Preferably, a traffic sign 90 " Speed Measurement "

The system of the signaling device for stopping the vehicles in front of the railroad crossing barrier system 1 preferably comprises signaling lights 81 in the roadway to highlight the vehicle stopper 83 until the barrier is lowered. The road signaling lights 81 are preferably located in the roadway at the location of the vehicle stopper 83 and are activated with it until the bolts are lowered, and are preferably bounded by a traffic sign 82 "Continuous line" usable to highlight the stopping position of the vehicles.

With this embodiment, multiple securing of the railway crossing barrier system 1 is ensured. Advantageously, the first safety measure consists in decelerating the vehicles by the deceleration section 118 using road signs 155 changing the maximum permissible speed from the beginning of the warning system of the rail system 1 until the gates have been lowered so that the vehicles cannot pass before crossing gates. preferably it consists of stopping the vehicles by the vehicle stopper 83 until the latches are lowered. Advantageously, the third safety measure consists in locating a vehicle stopper 84 exceeding the maximum permissible speed.

Preferably, the fourth security measure consists in highlighting the vehicle stopper 83 until the barrier is triggered by a light sign 201 preferably with a "STOP" sign and preferably with a countdown timer of 200. The fifth security measure preferably consists in highlighting the vehicle stopper 83 All the above safety measures are effective individually or in optional clusters to ensure level crossing safety.

Giant. 8 det. 1 illustrates a block diagram of an acoustic sensor 213 that detects the acoustic signal of railroad crossings and which is preferably solved by a directional microphone 74, preferably located at the focus of the parabola 75 facing the rail signaling device, and preferably the acoustic sensor 213 is 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 213 only to the opposite or to 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 railway equipment on one side.

The directional microphone 74, which senses a railroad audible warning signal at the level crossing, is directed to the level crossing and located in the dish 75, and a signal therefrom is applied to the input of the amplifier 76, preferably differential, and further converted to digital signal in the A / D converter 77 This signal is evaluated in the microprocessor 78 and compared to a recorded sample characteristic of the subject passage.
