Definitions
- the invention relates to a method and a device for avoiding unwanted influences of dual sensors in axle counting systems according to the preamble of claims 1 and 7.
- Axle counting systems are used for free and busy reporting of track sections in the railway network.
- Inlets to a track section are monitored with doubled wheel sensors (so-called double sensors).
- double sensors As soon as at least one of the two wheel sensors of a double sensor is influenced by a railway wheel at an inlet to the free track section, the evaluation unit reports an occupancy for safety reasons and remains in this state.
- the second group includes procedures for distinguishing signals originating from railway wheels from other signals. Due to the required error safety, however, this technique has narrow limits. An example of this is provided by the filtering of the wheel sensor signals (see DE 23 19 164 C2), where shorter pulses are discarded than influences which are not caused by wheels. However, high speeds and small wheel diameters mean that only extremely short pulses can be discarded without impairing the safe detection of railway wheels.
- EP 1 086 873 A1 describes a possibility of interference filtering, which recommends the group-wise evaluation of the axes taking into account the pulling speed. In this evaluation, wheel sensor pulses are discarded which do not have the same pattern (direction of movement and speed of movement) as those of the other wheels on the same double sensor within one observation period.
- EP 0662 898 B1 recommends correcting any counting errors by comparing the number of axles of successive counting sections. The prerequisite for this, however, is an expensive superordinate logic as well as a simple track topology. A similar approach is pursued by DE 197 06 021 A1.
- the aim of the present invention is to activate the double sensor for counting exactly when a train is approaching, and to switch the double sensor insensitive to undesired influences as soon as there is no rail vehicle in the surrounding area.
- the secure information that there is no rail vehicle there, is obtained for this purpose directly from the adjacent monitoring sections. As a result, no further aids or detectors are necessary in order to activate or deactivate the counting in good time.
- Track areas (tracks and stations) to be monitored are regularly divided into individual sections, which are automatically monitored by suitable track-free signaling devices.
- the individual sections are directly adjacent to each other.
- the boundary points between two sections, that is, when using axle counting systems, the mounting location of the double sensors are framed on both sides by free field sections, which can always provide the secure information on whether this section is free of rail vehicles. This secure information can then be used to temporarily disable counting by the dual sensor.
- the functionality of the double sensor is permanently monitored. Failure or damage will be detected immediately.
- signal patterns can be defined depending on the requirements of the rail operator, which should lead to an occupancy of the double sensor and the two associated free reporting sections. Application can find this in the detection of vehicles that are used in an outdoor reporting section (trolley), so do not run properly over the rail to the Free Signal section.
- activation by certain signal patterns can also serve to increase security. This prevents in the case of a very unlikely but possible failure of a double sensor that the following dual sensors are not activated in time.
- FIG. 1 shows the schematic representation of a double sensor for detecting and counting rail vehicle wheels in axle counting systems
- Figure 2 is a schematic representation of a track area with free field sections and double sensors for automatic axle counting and
- Figure 3 is a flow chart of the method for activating or deactivating the wheel sensors according to the invention.
- FIG. 2 shows the arrangement of double sensors 3 at the inlet and outlet of free-field sections.
- Track sections IM, IV are bounded by two double sensors each, switch sections I 1 II of 3 double sensors each. The number may vary depending on the track position. Exiting rail vehicles from station A drive over the double sensors a, b or d and thereby occupy the free field sections I or II.
- the wheel sensors a, b and d are either always activated or are activated by secure arguments (driving license, track circuit).
- the wheel sensors c, e and f are inactive as long as the two immediately adjacent free field sections are free (I and II for wheel sensor c, II and III for wheel sensor e and III and IV for wheel sensor f). As soon as the free-field systems of sections I or II no more free message occurs (by rail vehicles or error message), the wheel sensors c and e are activated. In the further course, by occupying the section IM, the wheel sensor f is activated. This scheme can then continue indefinitely, as well in the opposite direction. In the following, the method according to the invention will be described in detail with reference to FIG.
- step S200 the double sensor is activated to count in step S200.
- step S201 it is determined whether the adjacent free field sections are free of railway vehicles. If the result is NO, the program returns to step S200, if the result is YES, it is checked in step S202 whether there are further arguments for compulsorily activating the counting capability. In the positive case, the program proceeds to the program step S200, in the negative case to the program step S203. Here it is determined whether the double sensor is functional. If NO, the program goes to step S205 and reports an error to the axis counter. After that, in step S200, the double sensor is activated again for counting.
- step S203 If the result in step S203 is positive, it is checked in step S204 whether certain signal patterns were identified which should lead to an error message. If NO, the counting function of the wheel sensor is deactivated and then returned to the program step S201.
- step S205 If a corresponding signal pattern has been detected (YES), the program proceeds to step S205 and to S200.
