Definitions
- the invention relates to a control method for safety devices, in particular traffic control technology, e.g. at level crossings, and a safety device to carry out this procedure.
- the object of the invention is to provide a control method for security devices that is almost independent of the number of objects approaching a security area and the frequency of these events reliably activate and / or deactivate the access control devices of this security area.
- a safety device is to be created to implement this control method. This security device should be able to distinguish 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 this affecting the sequence of the control method or the security standard offered by the security device.
- This advantage enables the monitoring area to be chosen to be of any size, since the number of objects located in the monitoring area, which may be increased as a result, 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 a feature that is easy to grasp and process.
- the detection device of the security device is further developed in an advantageous manner.
- contact-free contact sensors preferably induction loops
- induction loops are provided as detectors ensures that, depending on an object that is in penetrates the monitoring area or else leaves it, in each case only a clear signal is generated.
- the security device is additionally equipped with a direction detection, which allows the direction of movement of the objects penetrating into the surveillance area and objects leaving the surveillance area to be reliably ascertained.
- the deactivation of the access control devices can already be initiated when the security area is left by the object.
- an additional safety feature of the backup device is realized.
- the security measures initiated by an object moving in one direction can only be resolved again 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 further developed in such a way that the penetration of objects from any number of directions into the monitoring area is reliably controlled.
- the registration device is made up of individual modules formed by modules, the registration device can be put together in accordance with the desired security standard and the relevant security area.
- Advantageous further developments for a modular structure of registration devices are mentioned in claims 12 and 13.
- FIG. 1 shows a schematic diagram of a safety device
- FIG. 2 shows a schematic diagram of a second fuse device
- FIG. 3 shows a schematic diagram of a third fuse device
- FIG. 4 shows a schematic circuit diagram for a circuit part of a control module
- FIG. 5 shows a schematic diagram of a detail of the control module
- 6 shows a basic circuit diagram for a circuit part of the evaluation module
- FIG. 7 shows a basic circuit diagram for a further circuit part of the evaluation module
- FIG. 8 shows a basic circuit diagram of a detail of the evaluation module.
- the security area 3 has an access control device 18, not shown in the drawing, which includes, for example, railroad gates and signaling devices, such as traffic lights, to secure the level crossing.
- This access control device 18 is controlled by a registration device 19. This is done in the direction of extension of the track body 1 the safety area 3 is delimited on both sides by a first and a second switch-off loop 4 and 5.
- 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 embedded in 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.
- the train now passes the security 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 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 Counting device 12. This signal has the effect that the respective counting result is decreased by 1. If the result of the count is now 0, the security measures initiated to secure the security area 3 are withdrawn within a predetermined 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 first passed through 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 safety device, several trains can be in the Enter 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 safety 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 the further control module 16.
- the counting pulse which reduces 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 also has both a switch-off pulse and one of the relevant directions received the corresponding signal.
- 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 the sensors in these track systems who, for example, work with the axle counting customary in railway technology, a signal of such accuracy and quality is available that a counting result corresponding to the number of trains actually entering and / or leaving area 17 is available.
- FIGS. 4 to 8 show possible circuitry implementations of the control modules 10 and 16 and the evaluation module 6. Instead of a circuit implementation, it is also possible to generate the algorithms that are running 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 control devices of the applicant 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.
- the increased safety requirements to be met in traffic engineering due to the increase in traffic with regard to the available response times and the complexity are taken into account.
- a level crossing can be designed in the manner described such that, instead of the block operation previously customary in train control technology, it now masters the train sequence operation that is now more common.
- Control method for a safety device in particular traffic control technology, e.g. at level crossings, in which access to a predefinable security area (3) is regulated in such a way that an access control device (18) assigned to this security area (3) enables or blocks access, a monitoring area (3) surrounding the security area (3) 17) and a registration device (19) each intrusion into the surveillance area (17) and each leaving the surveillance area (17) of objects relevant to the security area is recorded with regard to the number of these events and in which the registration device ( 19) controls the access control device (18) as a function of this number to meet predefinable security criteria.
- Locking device in particular the recountleittech ⁇ technology, for example, associated with level crossings, with a predeterminable securing region (3)adossregelungseinrich ⁇ device (18) ⁇ and a this access control means (18) controlling registration means (19), the Detekto ⁇ ren (4 , 5, 8, 9, 14, 15), which any penetration of objects relevant for the security area (3) into a monitoring area (17) enclosing the security area (3) and each leaving this monitoring area (17) by these objects detect, and wherein these detectors (8, 14) with a detection device (12)
