Definitions

  • the present invention relates to a security system for providing a secured railroad crossing.
  • Unsecured level crossings are currently still a threat to people and material, because it is due to carelessness again and again to accidents, some of which unfortunately even end in death.
  • a sure prescription against avoidance of these accidents is the establishment of secured level crossings, which are usually equipped with a turnpike and optical warning lights.
  • these level crossings are usually controlled and monitored by signal boxes.
  • signal boxes In addition to this relatively high outlay for the equipment and connection to a signal box and for maintenance is also the cost of the electrical power supply added, so that alone here sometimes cable lengths in the two-digit kilometer range are required.
  • level crossings are for example from the German Offenlegungsschriften DE 197 25 320 A1 and DE 199 00 696 A1 as well as the German Patent DE 199 28 317 C2 known.
  • the present invention is therefore an object of the invention to provide a security system for a railroad crossing, which has a relatively high level of security and can still be designed considerably cheaper in price.
  • a security system which has a simplified island-like operable structure Nevertheless, due to the possibility of communication, it is able to receive data and / or to send data, in particular fault messages.
  • the optical warning elements comprise LED lighting means. At this point, when using LED bulbs known traffic lights with yellow and red light can be used from the road.
  • a particular safe and sufficient in terms of the required power power supply is obtained when the power supply unit is designed as a self-sufficient photovoltaic unit with a storage battery and / or if the power supply unit has an induction loop in which voltages are induced by the magnetic field of Tranktions Wegströmen.
  • the communication device can be configured as a GSM module or as a GSM-R module or as a UMTS module. Of course, other wireless transmission methods are also conceivable.
  • the control unit may be provided to control the power output of the power supply unit as a function of the availability of electrical power.
  • the control unit may be assigned a brightness sensor, wherein the control unit adjusts the emission characteristic of the warning elements as a function of the ascertained brightness. Even with this measure, it is possible to adjust the brightness of the bulbs to the ambient brightness and to consume, for example, at dusk and darkness considerably less electrical power for the bulbs.
  • LED signals for example, only subsets of the LED total can be controlled.
  • time intervals can be defined in the control unit during which electrical consumers are switched off. For example, larger gaps in the timetable or even the night can be defined as such intervals on a siding transition. But it may also be possible that the entire security system only turns on when a train has operated the first rail contact and turns off again when the train has pressed the last rail contact.
  • At least one radio clock can be assigned to the control unit for adjusting the time intervals.
  • the drawing shows a schematic representation of a railway line S with four level crossings BUel to BUe4, which are each secured by a security system SA according to the present invention.
  • Each security system SA comprises on the track side three pairs of train direction resolving rail contacts SK1, SK2 and SK3 and a light signal LS on each side of the track.
  • a solar module SM and an induction loop L are provided for inducing voltages by reverse transient currents.
  • each security system SA comprises a control unit SE which has a programmable logic controller PLC, an interface I_SK for the rail contacts SK1 to SK3, an interface I_LS for the light signals, a power supply unit PS and an interface I_GSM for wireless communication.
  • the PLC is also assigned a brightness sensor HS and a radio clock FU.
  • a train on route S travels from station A to station B, it passes the first level crossing BUel.
  • the first rail contact pair SK1 is activated.
  • the state of charge of the power supply unit PS and the signal of the brightness sensor HS are queried and a corresponding control of the light signals LS, which may optionally also have an audible warning element made.
  • the configured as LED array light signals LS are controlled in accordance with the brightness and the state of charge in a special way to deal rationally with the available energy.
  • the control is provided, for example, that with decreasing brightness, the number of brought to light LED's decreases and decreases with decreasing state of charge, the blinking time and / or the period between two lighting phases is increased.
  • lightning durations of only 1/1000 sec. can be provided, as are known, for example, from the energy-saving firing of aircraft.
  • the light signals LS are then switched off and the control unit SE is again switched to a stand-by mode with the operation of the rail contact pair SK3 arranged directly in the direction of traction of the rail contact pair SK3 arranged directly in the vicinity of the level crossing BUe1.
  • the SPS further defines a number of fault criteria, such as "rail contact pair SK1 or SK2 not actuated within a predetermined period of time", “no current flow or excessive current flow to light signal LS", “low battery state” or the like, overrides the control unit its communication interface I_GSM from a fault message to a the route S controlling control system CS.
  • a control system-side control unit SEL also has the interface I_GSM, a programmable logic controller PLC and an interface I_CS to the control system CS.
  • the security system SA can then be remotely tested by the control system-side control unit SEL or checked locally by the control unit SE.
  • a security system SA is created, which is particularly inexpensive in terms of initial installation, and still has a high availability while maintaining good maintainability. Due to the intelligent control of the power consumption, it is thus also possible to operate warning events in the case of a low storage state of the energy supply unit PS.
