Definitions
- the invention relates to a method for transmission a control signal to one at a drive power feed point fed into a traction current conductor, electric drive current powered vehicle connected to the Contact conductors using a drive current collector is electrically connected in such a position that the drive current collector together with the drive current feed point forms a route section, with the The control signal is fed into the traction current conductor is and the control signal on the vehicle side with an inductive receive current sensor coupled to the contact wire becomes.
- the rail vehicle To receive the control signal is the rail vehicle with two inductive on the contact wire coupled current sensors equipped in the form of two coils; one of the two current sensors is on one Vehicle end and the other of the two current sensors on the attached to the other end of the vehicle. How the disclosure can also be removed to receive the control signal both current sensors used.
- the invention has for its object a method of to further develop the type specified at the outset in such a way that the transmission of the control signal to the vehicle by im Interference frequency components contained in the drive current as far as possible is unaffected.
- a major advantage of the method according to the invention is to see that only to receive the control signal a current sensor is used that is outside the Route section lies; because only one outside of Current sensor section ensures a undisturbed reception of the control signal.
- This fact can be explained as follows: When transferring the drive current from the drive current feed point to the drive current collector Sparking occurs occasionally or arc generation by the drive current collector, whereby high-frequency interference currents in the contact wire be generated; these interference currents flow from the Drive current feed point to the drive current collector of the Vehicle and then via a return line, e.g. Rails in railbound vehicles, to which Drive current feed point back, so that the through the drive current feed point and the drive current collector limited section with these high-frequency interference currents is applied.
- a return line e.g. Rails in railbound vehicles
- the method according to the invention is to ensure reliable inductive Transmission provided that the control signal from Contact line conductors to a return conductor of the control signal transmit a low-resistance suction filter for the control signal is, the stationary, for example, on rail vehicles Track, is arranged such that the current sensor is spatially between a control signal feed point of the Contact line and the suction filter.
- the control signal to the can be particularly reliable Vehicle transmitted when a binary control signal coded signal is transmitted because binary coded signals enable the use of additional control bits with which the received control signal in the vehicle Transmission errors can be checked.
- the control signal can be particularly simple and therefore advantageous be transmitted if an FSK as a binary coded signal (Frequency Shift Keying) signal, an OFDM (Orthogonal Frequency Division multiplexing) signal or a spread Spectrum signal is transmitted.
- FSK Frequency Shift Keying
- OFDM Orthogonal Frequency Division multiplexing
- the invention also relates to a receiving device for receiving a control signal for one Vehicle with two drive pantographs Current sensors on both sides of the drive current collector are arranged. Such a device can also be used can be found in the aforementioned disclosure.
- a receiving device based on the previously known Establishment in accordance with the aforementioned disclosure is further developed in that the transmission of a Control signal by contained in the drive current Interference frequency components are not affected proposed according to the invention with claim 7.
- This Receiving device according to the invention is characterized by this from that it has a switching device that those Current sensor for receiving the control signal selected by the two current sensors has the lower total received power.
- the main advantage of the arrangement according to the invention is in that guaranteed due to the switching device is that the control signal is always when operating the vehicle is only received with the current sensor that outside of the by the drive current feed point and the Location of the drive pantograph specific section of the route lies; because the switching device always activates one Current sensor for receiving the control signal, the one has lower overall reception power.
- flows over the part located in the route section of the contact wire both the control signal current and the drive current with its high-frequency interference so that the current sensor located in the route section must have a significantly greater total reception power than the current sensor that is outside of this Route section is located outside of the Section only the control signal current in the traction current conductor flows.
- the switching device in the receiving device according to the invention is thus the one Current sensor selected with which the received signal can be received more reliably because the selected one Current sensor not with its own drive current and therefore not with those contained in the own drive current Interference currents is applied.
- FIG. 1 shows an embodiment an arrangement for performing the invention Method and an embodiment for receiving device according to the invention.
- the figure shows a rail vehicle 5 with a drive pantograph 10 to a contact wire 15 as Contact wire is connected. Is on the contact wire 15 a drive voltage at a drive current feed point 20 Among other things, through which a drive current Ia through the contact wire 15, the drive current collector 10 and a drive motor 21 of the Rail vehicle 5 flows. The reflux of the drive current Ia is ensured by rails 22 on which the Rail vehicle 5 runs.
- the drive current feed point 20 and the drive current collector 10 or its location lay one Section 25 fixed.
- a control signal feed point 30 there is a control signal in the form of a control signal current Is in the contact wire 15 fed.
- the control signal current Is arrives at the rail vehicle 5 and a suction filter 35 through a series resonant circuit with a capacitance C and an inductance L is formed and that together with the control signal feed point 30 defines a further route section 40.
- the return flow of the control signal or the control signal current Is is guaranteed by the rails 22.
- This further Section 40 is therefore the control signal or Control signal current Is transmitted over the contact wire 15.
- the Rail vehicle 5 has two current sensors 45 and 50 in the form of antennas, for example designed as coils, which inductively at a distance of approx. 0.5 m to the Contact wire 15 are coupled.
- the one of the two Current sensors 45 are located in one section of the route 25, whereas the other of the two current sensors 50 lies outside of this section 25. With the two Current sensors 45 and 50 determine current measured values that through the contact wire 15 on the respective Specify current sensor location current flowing.
- the current measurement M1 of the current sensor 45 thus gives the current Ia + Is in the contact wire 15 and the current measured value M2 the current measured value Is in the contact wire 15 on; it is assumed that the Drive motor 21, be it on its own or by corresponding executed, assigned to the drive motor 21 Operating current filter circuits, for the control current Is so is high-impedance that an outflow of the control current Is through the drive motor 21 is negligibly small.
- the two Current measured values M1 and M2 each arrive at an input one Switching device 55, a control signal evaluation device on the output side 60 is subordinate.
- the switching device 55 and the control signal evaluation device 60 and the two current sensors 45 and 50 form a receiving device 65 for the rail vehicle 5 for receiving the Control signal or the control current Is.
- the two current measured values M1 and M2 are compared in the switching device 55 with regard to their total received power. It is found that the total received power P1 of the current sensor 45 is significantly greater than the total received power P2 of the current sensor 50; because it applies: P1 ⁇ (Ia + Is) 2 >> P2 ⁇ Is 2 since the drive current Ia is significantly larger than the control signal current Is.
- the switching device 55 selects the current sensor 50 to receive the control current Is, since the current measured value M2 of the current sensor 50 free of the drive current Ia and thus free of high-frequency interference currents contained in the drive current Ia and transmits the current measurement value M2 to the control signal evaluation device 60, in which the control signal or the control signal current Is evaluated.
- the suction filter 35 is between the contact wire 15 and the rails 22 attached on the track side. Instead, it is also possible to use the suction filter 35 to be attached to the rail vehicle.
- the electrical contact to the contact wire 15 is in such a case, for example to ensure by an additional pantograph which is to be arranged on the vehicle in such a way that it is for reception of the control signal or control current Is suitable current sensor 50 spatially between the control signal feed point 30 and the suction filter.
- the current sensors 45 and 50 are exemplary embodiments provided with which the current measured values M1 and M2 for the Switching device 55 are measured; at accordingly configured switching device 55 is also possible, instead of the current sensors 45 and 50 of different types To use current sensors, namely those with each the current flowing in the contact wire 15 at the respective point proportional current or voltage measurements for the Switching device 55 are formed.
- control signal or control current Is for example binary coded signal, preferably an FSK (Frequency Shift Keying) signal, an OFDM (Orthogonal Frequency Division Multiplexing) signal or transmit a spread spectrum signal become.
- FSK Frequency Shift Keying
- OFDM Orthogonal Frequency Division Multiplexing
- the method according to the invention can advantageously for rail vehicles, trolleybuses (trolleybuses), Gondola lifts, monorails or other electrically via one Contact conductors driven vehicles are used.
- the contact wire can be a contact wire (e.g. B. overhead line in rail vehicles) or by a Act track or the like.
