Technical field

The invention relates to a safety device, in particular a safety device at a level crossing.

BACKGROUND OF THE INVENTION

In the current state of the art, a level crossing barrier system does not solve an obstacle, for example a vehicle that remains on the track during crossing and can cause an accident with an approaching train. All the gates are lowered simultaneously, so that the vehicle that enters the track when the gates are lowered is blocked in the track by the barrier 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, will remain in the yard and cause accidents.

SUMMARY OF THE INVENTION

The shortcomings of the prior art are solved by the crossing safety device, when the barrier system is triggered, first the barriers in front of the rails are lowered and then after a settable time the barriers behind the rails are released, allowing the vehicles to leave the track. Preferably, the detector detects the space on the rails and, upon detecting an obstacle for the train set, delays the lowering of the barriers behind the rails or stops it until the railroad leaves the obstacle.

At the same time, it sends an alarm to the train control center and to the arriving train set via a wireless link. At the same time, the device triggers an alarm siren and preferably a voice prompt to release the tracks.

Preferably, the camera transmits video from the transition area to the control room and / or train set. The train set preferably informs the driver of an obstacle, and it slows down the train set speed so that it can brake or slow the train in time or decelerates the train set automatically.

Advantageously, an additional level crossing signaling is visible in the area of the barrier system, visible to the approaching vehicles, preferably a traffic light 1-3 colored, similar to a traffic light at a road junction. This will ensure that the vehicle is stopped before the gates are lowered in red. The communication module, which is connected to the control unit that controls the barrier system, sends data information to the train set and the train control center directly and preferably also •

to the server, which can be accessed by the selected participants which are: train set, dispatching, train control, firefighters, police, other participants. The control unit is connected to the detector and cameras and other sources, from which it receives information about the state of the barrier system. It controls the barrier system, signal, semaphore, voice unit and siren.

In the process of closing the barrier system 1, the signal 3 is activated, preferably consisting of two red alternating flashing lights. After an adjustable time, the barriers 2p in front of the rails will start lowering. After an adjustable time, preferably the expected time required to leave the track by a vehicle, the barriers 2z are lowered behind the rails.

Advantageously, the barrier detection sensor 4 in the barrier system space detects the barrier system space 1 on the rails 23 and, upon detecting an obstacle for a train, for example a vehicle 5, sends a signal to the barrier control unit 6 controlling the barrier system 1. behind the rails until the exit of the rail space obstruction 9. At the same time, the communication module 7 preferably causes an alarm in the train control station 11 arriving to the train set 12 and to the other selected participants 22 by means of wireless communication 13.

At the same time, an alarm siren 8 sounds in the region of the barrier system 1, alerting to the necessity of quickly removing the obstacle 9 of, for example, the vehicle 5. Preferably, a voice message 24 is produced from the voice unit 24. The data set and / or voice communication takes place over the wireless communication 13. The train set 12, after receiving the obstacle information 9, informs the train driver visually preferably on the monitor display 25 or The driver reduces the train speed manually or the control unit 28 automatically, preferably gradually, so that he can stop in time if the obstacle 9 is not removed. Preferably, a display 14 is placed on the label 3 with a numerical indication of how much time is left to lower the barriers 2p in front of the rails. Preferably, a barrier display 31 is shown on the label showing a simulation of an open barrier, preferably in white or green, which turns red and the display simulates a closing barrier before the barriers 2p in front of the rails begin to close. Advantageously, a semaphore 15, preferably one to three-color, visible to vehicles arriving at the barrier system 1, preferably similar to a three-color traffic light, is located at or at an optional distance ahead of the barrier system and signal 3. In accordance with the signaling signal, the green light changes to orange and then to red before the bolts 2p in front of the rails are lowered. The monochromatic traffic light 15 signals a red light, the two-color traffic light is orange.

• ♦ ·

The communication module 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 for exit in the event of a collision in the space in the barrier system 1.

The camera 10 sends to the police all the necessary data to penalize the side of, for example, the driver of the vehicle 5, which caused the obstruction 9 to be placed on the track, for example the vehicle license plate. If 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, for example to descend the parking lane 20 and wait there for the police.

Preferably, the communication module 7 sends data to a server 21 to which selected participants 22 have access, for example a train control station 11, a train set 12 over the Internet.

They have access to the situation data on all barrier systems 1, which are equipped with a communication module 7 and associated units for sensing or detecting obstacles such as cameras 10, sensors 4.

Giant. 1 det.3 illustrates how selected participants 22 are equipped with a display device 29, preferably comprised of a computer with a monitor that is adaptable to one or preferably multiple displays 32 on the screen to view multiple barrier systems 1 at a glance. Thus, the train driver can watch live 1 bolt systems on the route he travels in advance.

Giant. 2 shows a block diagram of a device for securing the barrier system 1 with a control unit 6 which controls the barrier system 1, a signal 3, the control unit 6 receives a semaphore 15, a voice unit 24, an alarm siren 8, information from an obstacle detection sensor 4 in the barrier system space; camera 10 and other sources of information 30.

It sends information via the communication module 7 to the server 21 to which selected participants 22 have access such as train set 12, train traffic control center 11, firefighters 16, other participants 64, police 17, which preferably controls the road display 19. The communication module 7 is adaptable for direct connection with elected participants 22.

Giant. 3 shows the barrier system 1, where the right-hand space 35 is detected by the right-hand sensor system 48, and if they detect a right-hand obstacle therein, it prevents the right-hand bolt 60 from being triggered behind the rails. In case it is partially or fully lowered, it is raised via the train control unit 28 of FIG. It will allow it to be triggered until obstacle 41 is not detected by the sensor system 48. The "left" "right" barrier position is viewed from the S direction. The "front" and "behind track" positions are taken from the driver's point of view towards crossing. Similarly • ·

3, with the left sensor system 54 with sensors 44. 45, 55 and 56 detecting an obstacle 59 left behind the rails. The right hand rail 60, the right hand rail 61, the right hand rail 62 and the left hand rail 63 also control the bar system with the train control unit 28, and if the sensor systems 48 and 54 do not prevent triggering, all barriers are triggered. 60, 61, 62, 63 simultaneously.

The sensor system 48 is preferably operated from a plurality of sensors preferably from a sensor 37 first right of the rails, a sensor 38 second right of the rails, a sensor 49 first right of the rails and a sensor 50 second right of the rails which simultaneously detect passing vehicles with In the event that there is no consensus in the detection of all sensors, the barrier system 1 triggers an alarm in the train control center 11 via the wireless communication 13 for fault shutdown as shown in Fig. 1.

Giant. 4 and its detail 1 show a system of a signaling device for stopping vehicles in front of a railway system 1 of a barrier of a railway crossing, preferably formed by a traffic light 15, located at an optional distance, e.g.

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 barriers 2 with the "STOP" signal, stops vehicles arriving at barriers 2 even before they cross the hazard warning lights 106 only after the barriers 2 have been triggered. to 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 warning lights 106 preferably by the optical sensor 211 and the barrier opening 2 by the light detecting sensor 121 or both by the camera sensor 212. Alternatively, the detecting unit 73 detects the alarm ring preferably by the acoustic sensor 213.

The activation of the "crossing warning lights 106", eg by alternating blinking of two red lights, is detected by this detection unit 73, which is used in the event that a direct electrical connection is present. 9 connections on railroad equipment with warning lights 106 otherwise the control unit 108 is coupled directly to the electrical barrier signaling device for alarm and ring information. In the case of using the detection unit 73, preferably constituted by the sensor 211, the warning light activation information 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 transmits the warning light activation signal 106 to the control o

a light semaphore 103, preferably consisting of a tricolor semaphore 204. The barrier trigger 2 is transmitted by the detection unit 73, preferably constituted by the triggered detector 121, to the control unit 108, which turns the traffic light 204 back to "LEAVE", preferably with a green light, which preferably follows an orange light.

In the case where the traffic light 103 is a two-color traffic light 205, it lights up with a red signal light when converted 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 comprised of an optical sensor 211 and / or an acoustic sensor 213 and / or a camera sensor 212 and / or a detecting sensor 121 triggered.

latches. 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, the optical 211 and the acoustic 213 are preferably located directly on the barrier rail device or on a separate forward post 214.

The maximum distance 119 of the traffic light 103 from the barriers 2 is preferably selected so that vehicles at a maximum 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. they are still on top so that if they do not follow the traffic rules and enter the level crossing when the hazard warning lights 106 are activated, they will have enough time to safely pass the crossing before the bolts are lowered. The distance 109 is preferably determined according to the time of the warning signal before the barrier 1 starts, which starts about 30 seconds after the warning lights 106 start flashing. Just before the barrier 2 starts, other cars will not pass to the barrier because they are stopped by traffic light 103 in advance.

Although the control unit 108 switches the light semaphore 103 to "SLEEP" after the bolts have been lowered, the vehicles, if initially stopped, can now arrive at the latches that have been lowered. 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 108 is set to "OFF" only when the warning lights 106 flash, i.e., after the gates have been raised and not when the gates have been lowered. The signaling device thus modified is also applicable to unprotected crossings that do not have gates.

Advantageously, a deceleration section 118 is provided in front of the traffic light 108 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 is preferably activated depending on the activation of the "Maximum speed limit" traffic light signs 110, preferably activated together with the crossing warning lights 106 or the traffic light 103. The traffic light 110 is located on a separate post 112 or post 113 of the traffic sign 102 The deceleration section 118 of the barrier crossing is preferably implemented to slow down the traffic of vehicles before the activated barrier 2. The warning lights 106 are activated and start to signal preferably the flashing of the barrier opening and a selectable number of traffic lights 110 at the maximum permitted speed. which lights up and displays an adjustable speed of, for example, 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, at the same time as the warning lights 106 indicate the upcoming barrier opening.

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 signal lights 205 of two side-by-side alternating intermittent lights, which are activated for the "STOP" signal and switched off for the "OFF" signal.

Preferably, a semiconductor 103 is provided with a countdown timer 200 and a traffic light 201 highlighting the semaphore with inscriptions and / or symbols, such as "STOP", 20s, such as

NA • • • • • • • • • • • • • • • • • • • WARNING CAMERA

RED ”, with driver information preferably activated when the hazard warning lights are activated.

Preferably, a camera model 203 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 for stopping vehicles before the crossing barriers 2, where the deceleration section 118 is completely omitted.

Giant. 5 shows a signaling device for stopping vehicles before crossing, complemented by a combined deceleration section 122, where the deceleration is realized both by visibility of the activated traffic lights 110 when the hazard warning lights 106 are triggered, but also by the radar unit 116 preferably a mark 110 positioned when registering a vehicle traveling above an adjustable speed thereon. Advantageously, a traffic sign 120 "End of all prohibitions" is placed downstream of the traffic sign HO. Preferably, there is a vehicle speed camera mock 117 which is interchangeable with a real camera, so that savings for the real camera are achieved because the driver does not know when it is deployed. For a greater effect when the vehicle is passing, camera light 117 flashes to appear to be recording.

The combined retardation section 122 may be optionally applied multiple times to enhance the effect. It can be used in road traffic with or without barriers. In this case, the traffic light 110 is only activated from the radar unit 116, which is also located in the traffic light 110.

The combined deceleration section 122 is preferably followed by a stop section 115 where the radar unit 116 turns the traffic light 103 to "STOP" by the control unit 108, preferably red when the vehicle arrives at a speed above the adjustable value, even though the warning lights 106 are not activated. . When activated, they do this by changing to "STOP" themselves.

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 110 is activated and the traffic sign 120 is not activated or not deployed. The speed on the radar unit 116 is adjustable to a speed that is selectable by a value higher than the maximum speed allowed for the selected vehicle tolerance.

• • •

The stop section 115 is usable in traffic even without barriers 2. In this case, only the radar unit 116 represents the traffic light 103. When the warning lights 106 are activated, the light sign 120 is not activated to maintain a reduced speed, for example 30 km / h.

The dummy 117 is preferably also positioned on the traffic light 103, preferably on the 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 119 of the radar unit located in front of the traffic sign 120, in addition to the current measured speed, preferably the sign slows to a certain speed, for example 30 km / h, referring to the speed indicated on the traffic sign 110 that follows.

Camera 117 '. replaceable by a dummy, it captures not only the speed of the vehicle, but also the non-stop at the red traffic light 103,

Giant. 6 illustrates a further barrier to the passage of the driver to the bolts 100 when it has passed the red traffic light 103. The detector 136 formed by a camera or a sensor at the edge of lane 134 preferably controls the "No Entry" traffic sign or the traffic sign 132 Commanded direction of travel, where on the parked lane 133 the driver preferably sees the police waiting sign 135 and the exit 130 is preferably prevented by a remote-controlled barrier 130. Preferably, the communication unit 139 is adapted for voice communication with the supervisor and / or the police.

Giant. 7 illustrates an example of securing a level crossing against flashing warning lights by means of traffic lights located at junction and "T" junction 70. Traffic lights control junction 69 in a conventional manner by means of control unit 6 to which they are connected by connections 105. The intermittent intermittent traffic lights 15, which control lanes “A”, from which the access to barriers 2 are placed, switch to “STOP” mode, in which they are lit red and if they are lit in a different color, they change to red in a prescribed manner, means from green to orange. This will prevent the passage from lanes “A” to the barriers 2 The lane traffic lights “B” leading from the barriers turn green so that the 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 closed, preferably after detection by the barrier detecting sensor 121 and / or the warning light sensor 107 of the end of their activation transmitted over the link 105.

• · ·

Vehicle sensors 71 detect vehicles traveling on lane "B" from barriers 1 and, in the case of a detected vehicle, switch the junction control so that these vehicles preferably have a green light 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 between intersections and crossings at the time of signal activation 206 and "STOP" mode arrive at the very beginning of activation 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 close. Other vehicles that would be risky to cross are already detained by traffic lights 15.

Or, the traffic lights 15 do not control the intersection at the time of the lift bars 2, the traffic lights are off or flash orange. The traffic light that steers the 'B' direction is preferably not installed, and the vehicles in this lane are constantly free to pass.

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

Giant. 8 illustrates a preferred embodiment of a signaling device system for stopping vehicles in front of a railway crossing barrier system 1 with increased safety, which is achieved by combining a vehicle stopper 83 until the barrier is triggered, preferably with a deceleration section 118 using traffic signs 155 changing maximum speed; Preferably, the traffic signs 155 varying the maximum permissible speed are illuminated, preferably comprising a set of LEDs, or in a mechanical design, preferably comprising flip-flops.

The vehicle stop 83 for the time until the barrier is triggered is constituted by a command signaling 323 preferably consisting of a tricolor traffic light 204 or an alternately flashing traffic light 55. It is activated at the moment of the vehicle alarm signaling. warning ring time. Preferably, a vehicle recording camera 226 that has traveled to red is disposed on the vehicle stop post 83.

The vehicle stopper 84 of the vehicle exceeding the maximum permissible speed is preferably formed by a tricolor traffic light 54 and is activated when the vehicle exceeds the maximum: a. ·::: ·: · · .. ·· .. · ........

the permissible speed given by the traffic sign 155 changing the maximum permissible speed, or, if not activated, the speed given by a notice or the speed given by another road sign, and is preferably deactivated when the gates 2 are lowered.

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, it is ensured that the traffic speed signals 155 changing the maximum permissible speed are preferably activated at the beginning of the ringing of the railway crossing barrier system 1 or at the time of the crossing warning light 106 being turned on, and preferably are switched off at the end of the ringing of the rail system 1 of the level crossing barriers, ie when the barriers 2 are 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. 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 at the speed with which 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 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 started, and the vehicles traveling at unabated speed will arrive at the bolts for at least 10s before they start. signaling could easily run over it.

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, eg 3 axes, and if 240 m from the railroad crossing, it would arrive to it even 13s before their start, ie in the case of illegal entry to the crossing would have enough time to cross the crossing before starting the race .. On the other hand, the driving time for a vehicle traveling at reduced speed 15 km / h 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 signaling device system 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 signaling device system is preferably provided with a switchable 120 "End of all prohibitions" sign, preferably light or mechanical with slats, and preferably located on a post of the "Signals" signal 85 preferably at a distance of 80 m and 160 m from the rail system 1 crossing. 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.

The signaling device system preferably comprises a voice unit 24, preferably located on a vehicle stopper post 83, i.e. at a distance of about 80m from the level crossing, and the voice unit 24 preferably reports text such as "Stop here, camera on red" ". The signaling device system preferably also includes a second voice unit 24, preferably 80m in front of the first voice unit 24. The voice units 24 preferably turn off when the vehicle sensor 21 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 203, which serves to detect the alarm signal of the security device.

This column preferably also includes a traffic sign 91 'End of speed measurement' and an omnidirectional transmitter 79 for transmitting a signal for at least one of the traffic signs 85 'Traffic signals', the vehicle stop 83 the time until the latches are triggered. 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 separately to ensure crossing safety and optionally applied.

Giant. 8 det. 1 illustrates a block diagram of an acoustic sensor 210 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 directed to the rail signaling device, and preferably the acoustic sensor 210 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 audio.

The signal of the railway warning sound at the level crossing, preferably for each crossing 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 210 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.

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. 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 the omnidirectional transmitter 79, so that all the pass-through security devices fitted with the receiver 80 can use the signal.

Or, the transmitter 79 is adapted for duplex communication with a receiver 80 also adapted for duplex operation over a mobile network, preferably a local WIFI 87 network. This makes it possible to collect device status information from the status detectors 88. These are preferably registered in the memory of the microprocessors 78 and / or preferably sent over the remote network 88, preferably the mobile operator network, to the server 806 of the supervisory center 762 and from there preferably to the selected subscribers 22.
