Definitions

  • the invention relates to a control method for safety devices for level crossings and a safety device for a level crossing according to the preamble of claim 1 and 3 respectively.
  • DE-A-1 918 911 discloses a safety device for a level crossing and a control method for the latter, vehicle detectors with active guide loops arranged on the tracks at certain intervals from a path crossing (safety area) having influencing areas greater than the smallest vehicle length and are smaller than the largest vehicle length.
  • the object of the invention is to provide a control method for a security device for a level crossing that reliably activates and / or deactivates the access control devices of this security area almost independently of the number of objects (trains or rail vehicles) approaching a security area and the frequency of these events.
  • a security device for a level crossing is to be created, which can differentiate between objects entering a monitored area and leaving this area.
  • the object on which the invention is based is achieved by the control method described in claim 1 and by the safety device described in claim 3.
  • the control method described and when the security device described is used it is possible for any number of counting objects to be able to penetrate into a monitoring area surrounding the security area without the operation of the control method or the security standard offered by the security device being impaired thereby.
  • This advantage enables the monitoring area to be made as large as desired choose because the possibly increased number of objects located in the surveillance area does not reduce the security level to be achieved by the invention.
  • control of the access control devices for fulfilling predeterminable security criteria is based on an easy to grasp and process feature.
  • the detection device of the security device is further developed in an advantageous manner.
  • contact-free contact sensors preferably induction loops, are provided as detectors ensures that, depending on an object that enters or leaves the monitored area, only one unambiguous signal is generated.
  • the security device is additionally equipped with a direction detection, which allows the direction of movement of the objects entering the surveillance area and the objects leaving the surveillance area to be reliably ascertained.
  • the security area is limited by further detectors which are connected to an evaluation module, at the output of which a direction signal corresponding to the direction of movement of the object and a status signal which represents the leaving of the security area by the object, are available, the deactivation of the Access control devices are already initiated when the security area is left by the object. Because the direction of movement of the object is also queried, an additional security feature of the security device is realized.
  • the one in one Security measures initiated in the direction of the moving object can only be resolved by an object moving in the same direction. A direction-dependent check is therefore carried out to determine whether objects are still in the security area or are approaching it.
  • the security device is developed such that the penetration of objects from any number of directions in the surveillance area is safely controlled.
  • the registration device is constructed from individual modules formed by modules, the registration device can be put together in accordance with the desired security standard and the relevant security area.
  • the security area 3 has an access control device 18, not shown in the drawing, which, for example, railway barriers, and signaling devices, such as Traffic lights included to secure the level crossing.
  • This access control device 18 is controlled by a registration device 19.
  • the securing area 3 is delimited on both sides by a first and a second switch-off loop 4 and 5 in the direction of extension of the track body 1.
  • the switch-off loops 4 and 5 are induction coils integrated in the track body 1, the loop width of which is ideally chosen between approximately 4 m and 7 m.
  • the switch-off loops 4, 5 are each connected to an evaluation module 6.
  • This evaluation module 6 comprises an evaluation logic circuit 7.
  • a switch-on loop 8 is integrated in the track body 1 at a suitable distance from the securing area 3.
  • a direction detection loop 9 is additionally let into the track body 1.
  • the switch-on loop 8 and the direction detection loop 9 are each connected to a control module 10.
  • the control module 10 essentially consists of a safety logic circuit 11, which is operatively connected to a counting device 12.
  • an AND gate 13 is connected to the counter 12 within the control module 10.
  • the AND gate 13 has two inputs which are in signal connection with the evaluation module 6. There is an active connection between the control module 10 and the access control device 18 located at the level crossing.
  • a further switch-on loop 14 a further direction detection loop 15 and a further control module 16 constructed analogously to the control module 10 are also provided on the other side of the security area 3.
  • the track body area delimited by the switch-on loops 8, 14 is referred to as the monitoring area 17.
  • a train traveling in the direction of the security area 3 first passes the switch-on loop 8 and then the direction detection loop 9. Both loop bodies 8 and 9 have current flowing through them.
  • the magnetic field thus formed is monitored by the control module 10.
  • the changes in the magnetic fields triggered as a result of the train passage are detected by the control module 10 and evaluated in such a way that, depending on the sequence in which the respective magnetic fields are traversed, it is determined in which direction the train in question is traveling. It is thus determined that first the switch-on loop 8 and then the direction detection loop 9 have been passed.
  • Such a signal input causes the safety logic circuit 11 of the control module 10 to send a counting pulse to the counting device 12.
  • This counting pulse causes the counting device 12 to be increased by a factor of 1.
  • a possible further passage through the train would increase the counting result by a further factor of 1.
  • the access control devices 18 are activated by the registration device 19 in such a way that all predetermined security criteria are fulfilled following a predetermined procedure.
  • the train now passes through the safety area 3 delimited by the first and second switch-off loops 4 and 5.
  • This passage of the train is evaluated by the evaluation logic circuit 7 located in the evaluation module 6.
  • the direction of the moving train is determined again on the basis of the sequence of switch-off loops 4 and 5 passed through. If the determined direction of travel of the train leads from the switch-on loop 8 to the further switch-on loop 14, a "high" signal is transmitted to one input of the AND gate 13.
  • driving on the second switch-off loop 5 lying in the direction of travel is evaluated as a switch-off pulse which, after a corresponding evaluation by the evaluation logic circuit 7, has the result that the second input of the AND gate 13 is also set to "high".
  • the AND gate 13 outputs a counting pulse to a countdown input of the counting device 12. This signal has the effect that the respective counting result is decreased by 1. If the result of the count is 0, the security measures initiated to secure the security area 3 are withdrawn within a predefinable time. If the counting result is greater than 0, the security measures initiated are retained since this stipulates that another train coming from the same direction is located in the monitoring area 17.
  • the train first passes the further direction detection loop 15 and then the further switch-on loop 14. This passage through the train is also evaluated in the further control module 16. Whenever a direction detection loop 9, 15 is passed first and only then the switch-on loop 14, 8, the train passage has no influence on the counting result of the counting device 12.
  • a train passage in the other direction is analogous.
  • the safety device shown would even allow trains to enter the monitoring area 17 from both directions. This only makes sense if there are 17 switches and / or other alternatives in the monitoring area. Because each of the possible directions of travel is assigned a separate counting device 12, proper functioning of the safety device is nevertheless ensured at all times.
  • the safety device according to FIG. 2 can be significantly simplified. It is then only necessary to arrange a switch-on loop 8 and a switch-off loop 5 as well as the associated evaluation and control modules 6, 10. Even with this greatly simplified security device, several trains can enter the monitoring area 17 without the security guaranteed by the security device being impaired thereby.
  • FIG. 3 shows the basic circuit diagram of another exemplary embodiment of the securing device.
  • the counting devices 12 each associated with a direction of travel and the required AND gates 13 are arranged in the evaluation module 6.
  • the counting pulse increasing the counting device 12 is transmitted either by the control module 10 or by the further control module 16.
  • the counting pulse which replaces the counting device 12 is given separately for each direction by an AND gate 13 as soon as, as in the exemplary embodiment shown in FIG. 1, the AND gate 13 has also received both a switch-off pulse and a signal corresponding to the relevant direction .
  • the access control device 18 is connected to the evaluation module 6.
  • control method described can also be used in connection with safety devices that are already in operation. In this case, it is only necessary to ensure by means of an appropriate evaluation circuit that a signal of such accuracy and quality is available through the sensors located in these track systems, which operate, for example, with the axle counting customary in railway technology, that one of the number of actually in corresponding counting result is available for trains entering the monitoring area 17 and / or for leaving this area 17.
  • FIGS. 4 to 8 show possible circuitry implementations of the control modules 10 and 16 and the evaluation module 6.
  • a circuit implementation it is also possible to generate the running algorithms by means of a software solution. This is achieved in a particularly advantageous manner by means of freely programmable control modules, in particular by using the applicant's control devices known under the name SIMATIC S5.
  • the control method in connection with the claimed safety device offers a safety standard that meets the highest demands.
  • traffic engineering due to the increase in traffic the available response times and the complexity of the increased security requirements to be met.
  • a level crossing can be designed in such a way that, instead of the block operation that used to be common in train control technology, it now masters the increasingly common train following operation.
