Definitions
- the invention relates to a device and a method for locating a railway vehicle along a railway track equipped with a beacon system and more particularly to a device allowing precise and punctual localization of a rail vehicle in relation to a beacon emitting an electromagnetic signal for the transmission of information.
- the invention also relates to a antenna intended to equip a railway vehicle in such a device.
- the object of the present invention is therefore to propose a device and a method for localization of a railway vehicle which makes it possible to localize punctually and precisely the rail vehicle compared to a beacon system, in particular EUROBALISE type, which is simple and economical to produce.
- the invention relates to a device for the punctual location of a vehicle rail along a railroad track equipped with a beacon system, the beacons being intended to transmit information to the vehicle by sending a signal electromagnetic, the vehicle comprising an antenna having a first circuit receiver for picking up the electromagnetic signal emitted by the beacon which is crossed by the antenna, characterized in that the antenna comprises a second circuit eight loop receiver for precise timing where the antenna is centered on the beacon.
- the invention also relates to a method for the punctual localization of a vehicle fitted with a device according to any of the characteristics previously described, characterized in that the phase change of the signal delivered by the second receiving circuit with respect to the signal delivered by the first receiver circuit to deduce the instant when the antenna is centered on the tag.
- the invention further relates to an antenna for picking up waves.
- electromagnetic emitted by a beacon the antenna comprising a first circuit simple loop receiver for receiving information communicated by the tag, characterized in that it comprises a second circuit eight loop receiver for precise timing where the antenna is centered on the beacon.
- the antenna is on-board on a railway vehicle and cooperates with beacons conforming to the standard EUROBALISE.
- Figure 1 shows a point-in-time location device for a vehicle railway on a railway track with ground facilities that consist mainly beacons 2, of a type known per se, provided with their electronic control and fixed along the track in known locations.
- beacons 2 of a type known per se
- the location device also includes equipment on board of the railway vehicle which mainly consist of a receiving antenna and of an evaluation unit 6.
- the evaluation unit 6, which can be a calculator, is powered by its own converter and is connected to the antenna 1.
- the antenna 1 is located under the vehicle in a location such that the antenna 1 passes in the axis of the beacons 2 when the train is running on the track.
- the beacons 2 comprise a transmission circuit provided a transmitting loop intended to emit electromagnetic waves representative of the information to be transmitted to the vehicle.
- the beacons 2 are supplied with radiation from a transmitter on board the antenna 1 of the rail vehicle, the latter providing the energy necessary for the operation of the beacon 2 which is crossed by the vehicle rail.
- This electrical supply of the beacon 2 is produced for example by integrating into the beacon an antenna circuit provided with a connected take-up coil in series at the primary of an isolation transformer, the secondary of the latter being connected to the beacon transmission circuit.
- the tags 2 are in accordance with the European standard EUROBALISE, i.e. they ensure the communication by magnetic coupling with the antenna 1 of the vehicle in the band of frequency 3.9 - 4.5 MHz, these beacons having the advantage of being compact, with a length of about 50 cm and light, with a weight of about 5 kg.
- the antenna 1 of the vehicle comprises, in a manner known per se, a first circuit receiver 3 which consists of a single loop.
- the first receiver circuit 3 is intended to receive the signal emitted by the beacon 2 and is connected to the evaluation unit 6 of the vehicle which analyzes the information transmitted by the tag 2 crossed by antenna 1.
- the antenna 1 also includes a second circuit receiver 4 which consists of an eight-shaped loop, the latter being substantially concentric with the simple loop of the first receiving circuit 3.
- the second receiver circuit 4 is also connected to the evaluation unit 6 of the vehicle.
- the size of the figure-eight loop is close to the size of the beacon 2 emission loop in order to achieve optimal precision on the location of the antenna 1.
- the beacon 2 When the vehicle approaches a beacon 2 and the transmitter of antenna 1 of the vehicle is in the contact zone of beacon 2, i.e. the level of energy captured by the beacon on the ground is sufficient to ensure its operation, the beacon 2 emits an electromagnetic signal representative of the information to pass.
- This signal is picked up by the antenna 1 of the vehicle and in particular by the loop forming the first receiving circuit 3.
- the power of the signal picked up by the first receiving circuit 3, as a function of the movement of the antenna 1 carried by the vehicle according to l axis X, is represented in FIG. 3.
- the first receiver circuit 3 of the antenna 1 delivers a signal S 3 which is maximum over a relatively wide range which is centered on the contact zone of the beacon 2, the signal thus captured can favorably be used by the evaluation unit 6 to analyze the information transmitted by the beacon 2.
- the amplitude of the signal varies for cancel at the start and exit of the contact zone with, however, the presence of secondary lobes on either side of the contact zone.
- the signal emitted by the beacon 2 is picked up by the second receiver circuit 4 of the antenna 1.
- the power of the signal picked up by the second receiver circuit 4 as a function of the movement of the antenna 1 along the axis X is represented in FIG. 4.
- the second receiving circuit 4 delivers a signal S 4 which varies in amplitude at the start and at the end of the contact zone of the beacon 2 and which is zero in the center of the contact zone, that is to say when the crossing point of the eight loop is centered on the emission loop of the beacon 2.
- the signal S 4 also includes secondary lobes on either side of the contact area.
- the point localization method according to the invention therefore consists in detecting, at using the evaluation unit 6, the phase change of 180 ° between the signal delivered by the second receiving circuit 4 and the signal delivered by the first circuit receiver 3, in order to deduce the instant when the antenna 1 is centered on the beacon 2.
- Such a localization process makes it possible to identify the instant when the antenna 1 is centered on the beacon 2 with an accuracy of less than ⁇ 5 cm and therefore localize the point vehicle on the track with a precision of the same order.
- the location of antenna 1 relative to beacon 2 will only be validated if the signal emitted by the tag 2 contains an informational message, the evaluation unit 6 thus verifying that the detected phase change is accompanied by reception a clear message by the first receiver circuit 3 to validate the location.
- the security of the localization process can also be reinforced by the implementation in place of a voltage threshold in order to filter all phase changes untimely which can appear on the existing secondary lobes at the ends of the beacon contact.
- Such a device associated with such a method thus has the advantage of allowing a punctual readjustment, when each beacon passes, of the railway vehicle on the track rail with an accuracy of less than ⁇ 5 cm, and this while keeping a beacon EUROBALISE type standard widely used on rail networks.
- the location device and method according to the invention therefore make it possible, in simply equipping railway vehicles with an antenna according to the invention, very economically to obtain very good precision on the points of registration of the vehicle on the railway.
