Definitions
- the invention relates to a method for detecting hazard sources, mainly those in the railway sector, and in particular to an early warning system for detecting approaching rail vehicles according to the preamble of claim 1.
- the persons in the danger area of the tracks are subject to heavy stresses due to physical work, noise, dust and high or low temperatures.
- a further difficulty for the people is that the modern high-speed trains approach the track components very quickly and with relatively little noise.
- the security posts that trigger a typhon as soon as they have visual contact with an approaching train cannot reach reasonable warning times for the endangered persons, at least in the case of construction sites on high-speed lines.
- Security posts can be integrated into the train registration chain and can be connected by telephone to the responsible dispatcher. Nevertheless, a track construction site represents an inevitably increased risk in rail operations due to the necessary deviation from established operating modalities.
- the cause of some accidents in the past were, for example, reporting errors in the transmission of the train report, arbitrary deviations of the operating personnel on train vehicles from the content of a train report that has already been submitted or a start of construction activities in the track area earlier than registered with the responsible driving service.
- DE 42 14 271 AI discloses a method for detecting sources of danger and for emitting acoustic and / or optical warning signals for persons employed in the hazardous area. nen.
- the source of danger for example a train, is detected with acoustic body shell sensors.
- the signals emitted by these structure-borne noise sensors are amplified and then fed to an alarm device for emitting warning signals.
- the system proposed according to the invention supplements the existing security item and helps to rule out the possible cause of the accident by underloading the security item.
- This system can, depending on the railway operating concerns and the applicable safety regulations, safely replace the security post.
- the system according to the invention can advantageously be used on a free route and / or in the station area.
- the security system is based on the evaluation of sensor signals, in particular structure-borne sound vibrations in the rail area, and a wirelessly transmitted alarm, based on corresponding evaluation results, which prompts the people of a construction site to leave the rail area.
- the persons can be warned both via the conventional typhon and via an alarm device to be worn on the body.
- These alarm devices on the body warn the person optically by means of flashes of light and / or acoustically and by emitting a strong vibration in a sensitive body area, for example in the buttocks or in the hoof area.
- the advantage of the pulsed structure-borne sound signal described in the subclaims resides in the fact that a second structure-borne noise signal, which is completely different from the structure-borne noise of the moving train, is thus entered into the rail, which is generated by the train or rail vehicle passing, e.g. is drawn directly via the wheel flange.
- the solution of the pneumatic driveover contact presented in the embodiment of the invention consists of an elastically deformable body which has chambers with the same resting pressure at all times. If a wheel flange of a vehicle wheel runs onto the body, the volume of the chambers is quickly reduced, where the pressure in the chambers rises above the resting pressure. This increased pressure is implemented via sensors. By arranging two separate chambers one behind the other with separate pressure sensors, for example PE converters, the direction of the rail vehicle traveling over can be detected by the sequence of the sensor actuation.
- the sensor element or the sensor elements for detecting structure-borne noise in the rail are preferably located in a housing which can be attached to the outer surface of the rail head or the rail web by means of built-in magnets.
- the advantage of this type of attachment is that no special tools are required to attach the sensors.
- other fastening means can be selected which can only be handled with special tools.
- the housing has a system switch for starting up and switching off the sensors. Too To rule out any manipulation here, an internal electronic switch can be used, which can be activated and deactivated from the outside.
- one or more sensors or sensor groups are preferred which can cover a range from 20 Hz to 20 kHz.
- Structure-borne sound vibrations of around 12.5 kHz have proven to be particularly advantageous because they can be easily transmitted in the rail.
- optical sensors for example infrared sensors, or other electronic sensors, for example ultrasound sensors
- other evaluation criteria are required for these sensors.
- Such criteria can be pure light barrier techniques.
- image processing techniques which means that the sensor detects a striking part of a train, compares it visually, for example in image computers, and triggers an alarm signal when the train is recognized.
- the sensor for the structure-borne noise should be arranged as precisely as possible between two sleepers. Because of the flexibility of the superstructure, the highest speed of transverse vibrations has been determined between two sleepers.
- the entire security system must be able to be activated quickly and without laying cables and must be ready for operation.
- the alarm devices must not represent an additional burden for the working person or the security post.
- no electrical fields, signal systems or other devices may be disturbed by the safety system, on the other hand, the safety system may not be see fields but are not disturbed themselves.
- FIG. 2 shows a rail with structure-borne noise sensor in section
- FIG. 3 shows a rail with another structure-borne noise sensor in section
- FIG. 4 shows a rail with a pressure sensor in section
- FIG. 5 shows the pressure sensor according to FIG. 4 in longitudinal section
- FIG. 6 shows the rail with the sensor carrier in section
- FIG. 7 shows the arrangement of fastening elements of the sensor carrier
- FIG. 8 an optical alarm device with an alarm in stage I
- FIG. 1 shows schematically the safety system of the type according to the invention, which is installed ready for operation on the track systems.
- the security system 1 exists as an early warning system for the detection of approaching track vehicles or rail vehicles from a sensor unit 2, which is attached to the tracks 3 at a safety distance, which corresponds to the approach distance specified by the railway authorities, from an evaluation unit 4 for evaluating the measurement signals transmitted by the sensor unit 2, a transmitter unit 5 for forwarding the corresponding warning signals to the various receiver units and a charging station 6, which is used at the same time as the storage location of the system elements.
- a sensor unit 2 it is also possible to use a plurality of sensor units or groups of sensors which can be linked to one another.
- the sensor unit 2 can also be mounted at the work station.
- the receiver units are located on the protocol unit 7, on the compressed air bottle (Typhon) 8, on the construction workers or people in the track area on the body 9, and possibly also on an optical warning signal device 10.
- the signal transmission between the individual elements of the Security system 1 is preferably wireless.
- the sensor unit 2 is mobile and can be installed on the rails 3 by means of magnets, for example, or can be attached to the rails with special tools for more secure attachment.
- these sensors 11 should be particularly sensitive to measurement at the frequency of f 12.5 kHz, since the structure-borne sound vibrations of this frequency are particularly well propagated in the rail.
- an infrared or laser signal can also be used as a sensor, for example. There is basically no dead time of the sensor 11 between two alarms.
- a amplifier unit 13 generates amplified signals for transmitting the measurement signals to the evaluation unit 4.
- a device In addition to the driving noise generated by a rail vehicle (train) in the rail, a device can also be installed in front of a track construction site, which is actuated by the wheel flange 25 of the wheels 26 of the train traveling over it and an im. Dependent on the speed of the train - Pulse-containing structure-borne noise signal entered in the rail 27. As a result, two different signals are available for structure-borne noise evaluation: namely a continuous structure-borne noise level in the rail 27 caused by the train journey, which level is detected by sensors 11 and the active pulse-containing structure-borne noise excitation.
- the impulse-containing structure-borne noise is preferably introduced into the rail head 28, it being possible to use the other available sides of the rail 27 in addition to the rail surface.
- the mechanism triggered by the wheel flange 25 of the wheel 26 passing over can transmit energy to the rail 27 by means of mechanical, hydraulic or pneumatic means.
- This energy can be stored in a spring memory 29 or another suitable device.
- the stored energy triggers, for example, a hammer 30 which strikes the rail 27 with the force F and thus enters impulsive structure-borne noise into the rail 27, the actuation the impact object can be triggered mechanically, electrically, or also pneumatically or hydraulically.
- the solution according to FIGS. 4 and 5 consists of a pneumatic / electrical or hydraulic or / and pneumatic / electrical system actuated by the wheel flange 25 of the wheel 26 of the rail vehicle, on the inside 31 of the rail 27 of a track there is an elastically deformable body 32, for example made of rubber-like square material, so fastened by means of a holder 33 that it ends with the top edge or running surface 34 of the body.
- the body is so wide that a passing flange 25 runs onto the body 32 even when that Rail vehicle is pressed by centrifugal force against the opposite rail of the track and the flange 25 on the side of the sensor 32 (11 ⁇ is not in contact with the rail head.
- the necessary length of the body parallel to the longitudinal axis of the rail is determined by the two separate chambers 35, one behind the other. A constant static pressure is ensured in both chambers 35 and is monitored simultaneously. If the chamber pressure drops below the static pressure, damage to the system must be assumed. If necessary, a fault signal is then emitted.
- Pressure is implemented via sensors, preferably PE converters, so that the crossing of a train is clearly identified.
- Signal trigger means The system can be designed so that after a first drawing of a signal in a defined
- the preferably used PE converters close an electrical switch due to the pressure surge under defined conditions.
- the hardness of the rubber-like body 32 can be designed so that a person cannot trigger the sensor without the aid of tools.
- FIGS. 6 and 7 show the possibility of fastening the sensors 32 and 11 to the rails 27.
- This fastening system can be installed between two adjacent sleepers of a track.
- An L-shaped support element 36 is positively attached to the inside 37 of the rail foot 38.
- a threaded rod 39 which passes through the vertical leg 40 of the carrier 36, is screwed in as far as possible and prevented, that the carrier 36 can detach from the rail 27 again.
- the threaded rod 41 is provided with a plurality of elongated holes 42 which are designed such that the threaded rod 41 can be secured against unauthorized unscrewing, for example by a padlock.
- the padlock is suspended in the elongated hole between the rail 27 and the leg 40 of the carrier 36, which is closest to the threaded hole in the leg 40.
- the required sensors are attached to the carrier 36 at 43.
- the use of three threaded rods 39 and their placement at three different points on the carrier in the form of a triangle ensures that the carrier 36 no longer has any degrees of freedom in its movement behavior.
- the solution presented has the advantages that it can be used to quickly mount a sensor, prevents unauthorized removal of the sensor, it is impossible to loosen the fastening device by vibration due to the positive locking, and the sensor can be mounted on various rail profiles without further adjustment work .
- the sensor unit 2 in FIG. 1 has an energy supply in the form of batteries or rechargeable batteries 14 for continuous operation of 24 hours, and optionally thermal batteries 15 for displaying or reporting empty batteries / rechargeable batteries.
- a switch 16 for starting up the sensor unit 2 is located either on the outside or, for better security against intentional or unwanted incorrect operation, inside the sensor unit 2. In the case of the internal arrangement of the switch 16, this is activated from the outside by an additional electronic device .
- a test device 17 for testing the operational readiness of the system emits a warning signal when switched on and off.
- the sensor unit 2 transmits the amplified measurement signals to the evaluation unit 4. This evaluates the mean value from the measurement signals of all three coordinate directions and calculates the Gradient of this effective value.
- the evaluation unit 4 works in the three-channel system. The gradient consideration of the measured effective value is therefore to be selected so that the security system 1 also functions when vibration-emitting working systems are used in the measuring range of the sensor 11.
- the current measurement signal In order to trigger an alarm, the current measurement signal must have a larger value than a defined threshold value and a larger value than the signal of the last measurement cycle, so that vibrations from a permanent source are suppressed.
- the evaluation unit 4 sends a characteristic horn tone.
- Batteries or rechargeable batteries 18 serve to supply energy for 24 hours of continuous operation, and a physically different battery system, such as Thermal batteries 15 for displaying / reporting empty batteries.
- the evaluation unit 4 delivers the command to send a yes or no signal to the transmission unit 5, which transmits the corresponding signal to the various receivers.
- the transmitter unit also has batteries or rechargeable batteries 20 for power supply for 24 hours of continuous operation and a physically different battery system, such as Thermal batteries 21 for displaying / reporting empty batteries.
- the evaluation unit 4 also sends an activation signal to the logging unit 7.
- the logging unit 7 logs activation and deactivation of the system and individual alarms with the time and date.
- the construction site, date, period, responsibility and location are in the log header captured.
- the receiver 22 on the compressed air bottle (Typhon) 8 receives the signal from the transmission unit 5 and, in the case of the YES signal, activates the peripheral device Ty ⁇ phon 8 via a compressed air valve 23. Manual operation of the Typhon 8 on site is additionally possible at any time .
- Another signal from the transmitting unit 5 goes to the receivers of the individual construction workers who are carried on the body 9 of the people.
- These receivers 9 are worn, for example, on the buttocks or hoof area which is sensitive to vibrations and, in the event of a yes signal, warn by vibration of predeterminable intensity and duration.
- an optical stimulus for example a flash or a plurality of flashing lights, can be generated in the receiver 9 at a predetermined interval and a predetermined total duration and / or an acoustic signal can be emitted. There is no dead time of the receiver between two alarms.
- the receiver on the body 9 has an energy store 24 with a quick charge and full charge function.
- FIGS. 8 and 9 A special optical warning signal device is shown in FIGS. 8 and 9. Warning signals at track construction sites, which signal an approaching train, must indicate the current warning level to the track construction workers until a defined reset command. This can be one or more warning levels.
- the example in FIGS. 8 and 9 shows a two-stage warning signal device.
- This two-stage warning signal device 44 consists of a preferably round cylinder 45 with a movable backdrop. This backdrop releases a glass cylinder 46. There is a flash lamp 47 on the cylinder 45 which is switched on when a train is approaching. This approach of a train represents the alarm level I and calls for the work in the track area to be interrupted and for the passing train to be observed. The viewer first sees a black cylinder 45 below the flash lamp 47 at any time. If the backdrop is opened, which means warning level II and calls for immediate clearing of the track area, 46 daylight passes through the glass cylinder during the day. A light inserted into the glass cylinder is activated during the night. In both cases, the observer recognizes a cylinder as a black line interrupted by light.
- Such an indicator can therefore be used day and night, its signaling can be seen from all sides, the warning can be perceived under unfavorable optical conditions, and it is suitable for all conditions of rail operations. If the power supply fails, the optical alarm device 44 generally takes the highest alarm position.
- a reset signal causes the indicator 44 that the flash light lamp 47 goes out and the backdrop is closed again.
- the indicator 44 can be controlled manually on site or connected to the control center via other data transmission techniques, such as radio, cable, infrared or ultrasound lines.
- the start of a time slice of a system can be set to the start of a second or minute.
- the number and duration of the individual segments of a time slice are stored in the system of the transmitter, so that a system composed of different transmission units can orientate itself on the basis of the stored information about the time slice used and on the known, exact time so that mutual "plugging" of the transmitters is eliminated.
