Definitions
- the invention relates to a method for signal-technical securing rail-bound vehicles, which are connected via a data thennfunkksystem with at least one central monitoring device and a related safety system.
- train control systems are based on a train track side ⁇ locating means locating devices, such as beacons or axle counter. These train protection systems are highly centralized, so that the smallest changes ⁇ ments, for example, on the track layout, require considerable adaptation effort.
- Another disadvantage is that a high financial outlay is created by the setup, cabling and maintenance of external elements. Satellite-based methods currently do not provide sufficient recuperzi ⁇ sion to be set once the traditional backup method for locating.
- the invention has for its object to provide a method for signaling backup rail-bound vehicles and a related security system, which allow simple means, especially without track elements for locating a technical support for detecting and avoiding a collision hazard.
- the object is achieved in that the vehicles transmit their instantaneous position data via the radio data transmission system to the monitoring device, that a safety range dependent on a vehicle speed and a measured value dispersion of the position data acquisition method used and a warning range encompassing it are determined around the vehicles and that the monitoring device based on the vehicle-specific
- a security system in which a transceiver is provided on the vehicle side, whose transmitting component is connected to a device for position data acquisition, in which a device for determining a security area as a function of a vehicle speed and a measured value spread of the device for Positioning of the vehicle and a safety area comprehensive warning area is provided around the vehicle and in which the monitoring device comprises means for determining journey-determining data on the basis of the vehicle-specific position data, safety areas and warning areas such that collision-relevant Students- Lapses of security areas are avoided and collision-relevant overlaps of warning areas is counteracted, the driving-determining data, at least in the event of collision-relevant overlaps via the radio data transmission system to the affected vehicles are transferable.
- the vehicle In the safety area, the vehicle is completely, ie including entrained wagons embedded, the extent must correspond at least in the direction of travel at least the speed-dependent braking distance.
- the size of the security area is also dependent on the measured value scattering , ie on the measurement inaccuracy, in the position data acquisition. It should be striven that this safety area can never overlap collision relevant with the safety ⁇ range of another vehicle. For this purpose, set a warning area to the safety area around ges already been a backlash at its overlap with the warning area of another Fahrzeu-, if it is indeed plural ⁇ a collision-relevant overlap.
- Nonsecurity overlaps are possible in particular when two vehicles meet on rallelumblen Pa ⁇ or overtake without meeting for can. Even at scheduled scheduled at the identified position expected vehicles that wait for single-track on a neighboring station siding or a siding on driving license, can be recognized as uncritical.
- the monitoring means may evaluate starting from the start position of each vehicle on the basis of point position and the present position data of the vehicles without further Informa ⁇ functions the danger of overlaps.
- non-collision-relevant overlaps are detected by a token method.
- the token method known per se, it is ensured that only one vehicle always moves on the monitored route section under the full responsibility of the driver and all other vehicles are in overlapping warning zones or, if applicable, in overlapping security zones.
- the sequence must be manually controllable, wherein a token can possibly also be returned to the central monitoring device.
- the method of token-based restricts the movement of the vehicles, the driver of the moving vehicle is responsible for ensuring that no collision with a stationary vehicle occurs. The safety level achievable in this way corresponds to the previous safety on secondary lines.
- an emergency braking is provided according to claim 5 ⁇ .
- the vehicle-internally determined position data are determined according to the preferred embodiment of claim 6 satellite-based.
- the position data determination can be continued for the last projectable time using the last position and the speed.
- ⁇ can be used as well odometrisch determined position data.
- the relatively wide spread of the location data, in particular satellite location data is used for the determination of the safety area and the warning area and therefore no longer poses a problem. Since the vehicles are moving objects, the safety and warning area is speed-dependent for to individually determine each vehicle.
- the speed is not transmitted together with the location data to the central moni ⁇ monitoring device, also valid in the stretch maximummaige ⁇ speed for determining the safety zone and warning area can be used.
- different spreads occur with respect to the location accuracy, which also go into the determination of the warning and security areas.
- the stability of the radio data transmission Transmission are taken into account. Due to the use of radio technology, it can always come to a failure of the data connection between the vehicle and monitoring device. The maximum time for such a connection failure can be additionally included in the determination of the warning and safety area.
- the single figure shows two vehicles for a safety ⁇ range 1.1 and 1.2 and a warning range 2.1 and 2.2 in interaction with a central monitoring device 3.
- the vehicle not shown, are completely embedded in the security area JE INT 1.1 and 1.2, while the Warning area 2.1 or 2.2 completely covers the security area 1.1 or 1.2.
- the vehicles are equipped with Empfangsgerä ⁇ th to satellite positioning, the measured value litter ⁇ clothes, which can also include neighboring tracks, the extension of the security zone 1.1 and 1.2 and also 2.1 and 2.2 largely determines the Warnbe ⁇ rich.
- the vehicles ste ⁇ hen via data radio links 4.1 and 4.2 via wireless communication, for example.
- the surveil ⁇ monitoring device 3 provides the basis of the location data, security areas 1.1 and 1.2 and warning ranges 2.1 or 2.2 determines whether there is an overlap of warning areas 2.1 and 2.2 and, if so, whether this overlap is collision-relevant. The latter is only the case when the vehicles drive on the moving ⁇ che soft layer-specific driveway.
- the points ⁇ position is known in the monitoring device 3, so that the monitoring device 3 is able to recognize whether collision danger actually exists or whether the vehicles pass each other only on neighboring tracks, in which case also safety areas 1.1 and 1.2 at the overlap can be ⁇ shares.
- the monitoring device 3 Only in the event of a real risk of collision, the monitoring device 3 transmits warning messages to the vehicles involved, which are then decelerated in the responsibility of the driver or automatically forcibly braked via a ent ⁇ speaking vehicle device.
- the described method allows the use of inaccurate in-vehicle positioning methods, in particular satellite positioning, whereby a very high level of security can be achieved even without the use of the conventional, cost-intensive route safety technology.
