Definitions

  • the invention relates to a device for detecting the finish of participants of a race, in which the participants are each equipped with a transmitter that has at least two receiving antennas at the destination and receivers connected to the receiving antennas.
  • a competition timekeeping and display system is known (DE-OS 21 41 001), in which two receiving antennas are arranged at the finish line in the floor of the racetrack, which consist of adjacent conductor loops which are successively run over by the participants in a car race.
  • Each of the participants is equipped with a transmitter that transmits a selective identifier and receivers are connected to the receiving antennas that are selectively matched to the identifiers of the transmitters.
  • the receiving antennas When the receiving antennas are passed over, the transmitters generate signals in these which are evaluated and not only lead to the determination of the passage of the finish, but also to the identification of the subscriber concerned.
  • the signals generated one after the other in the two antennas are summed. The summation produces an overall signal curve with three voltage peaks which follow one another in time.
  • the evaluation or detection of such a signal curve using electronic means for the exact determination of the target passage is difficult.
  • the transmitter of every racing car generates approximately the same voltage curve over time on the antennas, the amplitudes of the curves can differ greatly from one another at different finishings. This can be due, for example, to the fact that the transmission powers of the individual transmitters are different, or to the fact that the transmitters are at different distances from the road. If the finish crossing signal is only generated after a proper sequence of three voltage peaks has been detected on the receiving antennas, then the racing car has already passed the finish line so that the indicated timing of the finish crossing does not exactly match the actual finish crossing.
  • the known antenna system is also sensitive to deliberately generated interference. For example, it is possible to set up a transmitter in the vicinity of the antenna system, which generates a signal curve with three voltage peaks according to FIG. 5 in order to simulate a target crossing.
  • the receiving system would also respond to such a stationary transmitter, since it only analyzes the total voltage curve at all three antennas together, but does not check whether the voltage maxima occur in succession at the individual antennas.
  • the object of the invention is to provide a device of the type mentioned, which enables a very fast and therefore exact determination of the finish and is insensitive to short and long-distance interference in that it only responds to moving transmitters, but not to stationary transmitters.
  • the two receiving antennas are arranged with a directional sensitivity essentially perpendicular to one another, and that a target cross-over signal is generated when the signal of one receiving antenna is above a high first threshold value and the signal of the other receiving antenna is below a low second Threshold.
  • the signal of the first receiving antenna rises slowly when a transmitter approaches the receiving antenna, reaches its maximum when the transmitter has reached the smallest distance from the receiving antenna and then decays again. In the vicinity of the target crossing in front of and behind the target, the signal level of the first receiving antenna exceeds the first threshold. This area is relatively large and is not sufficient for an accurate determination of the target passage.
  • the second receiving antenna whose main receiving direction is perpendicular to that of the first receiving antenna, determines the exact passage.
  • the signal that the transmitter of a subscriber approaching the target generates on the second receiving antenna rises with increasing proximity, but drops sharply to zero shortly before reaching the target and rises again sharply after crossing the target and then decays .
  • the sudden drop in this signal during the passage of the target is used to accurately determine when the target has been reached. Evaluating the signal of the two Receiving antennas can be carried out using simple technical means. All you need is two threshold switches to determine whether the two conditions of the AND condition are met.
  • the receiving antennas are induction loops, one of which is arranged in a substantially horizontal plane and the other in a substantially vertical plane.
  • the levels of the induction loops can cross each other in the middle of the loop.
  • the wavelength of the transmission signals should be large compared to the length of the loops in order to avoid standing waves on the induction loops.
  • the identifiers of the individual transmitters consist in the fact that each transmitter transmits a selective frequency to which the relevant receivers of the measuring device are tuned. This tuning can be done with crystal controlled oscillators. Different identifications are also possible due to different modulations of a single transmission frequency.
  • the induction loops are preferably sunk in the floor of the racetrack with main axes running transversely to the direction of movement of the participants.
  • Such an installation of the receiving antennas in or under the floor along the finish line avoids disturbances for the competition participants and the spectators. It is not visually recognizable at all and ensures high accuracy. It has thus been found that the presence of a transmitter can be determined with certainty in a range of a few angular degrees with respect to the vertical plane passing through the common axis of the receiving antennas.
  • the target crossing signal is therefore generated precisely when the transmitter in question is exactly above the target degrees below which the two receiving antennas are laid.
  • the induction loops are preferably attached to a common carrier body.
  • This can be a pipe.
  • the required dimensional stability of the two receiving antennas is thus achieved, so that no deformations of the induction loops can occur when laid in the ground.
  • the wires of the induction loops can also be attached to the inner wall of the tube.
  • the device shown is particularly suitable for detecting the passage of the finish in car races.
  • transmitters are attached to the individual racing cars, all of which emit different frequencies.
  • the transmitters are preferably mounted under the floor panels of the racing cars or embedded in a cutout on the floor panel. Their main direction of radiation is perpendicular downwards.
  • the racing car forms a shield that prevents a larger proportion of the radiation from being emitted upwards and to the sides. Due to the low ground clearance of racing cars, the transmitters are very close to the ground, so that they manage with low transmission power.
  • the two induction loops 10, 11 are laid below the finish line in the floor of the racetrack.
  • the direction of travel of the racing car is indicated by arrow 12.
  • the main directions of the induction loops 10 and 11 are transverse to the direction of travel 12.
  • Each induction loop consists of two parallel conductors 13, 14 which are connected at one end by a connecting conductor 15. The opposite ends of the conductors 13, 14 are connected to the evaluation device.
  • the conductors of the first induction loop 10 lie in a substantially horizontal plane, while the conductors of the induction loop 11 are arranged in a substantially vertical plane.
  • the levels of the two induction loops cross each other in the middle of the loop.
  • the ends of the horizontal induction loop 10 are connected to a series of selective receivers E 1 , only one of which is shown in FIG. 1, and the ends of the vertical induction loop 11 are connected to a series of frequency-selective receivers, of which only one is shown in FIG. 1 Receiver E z is shown.
  • Each transmitter or racing car is assigned a pair of receivers E i , E2, which is tuned to the frequency of the transmitter in question.
  • FIG. 2 shows the voltage curve U 1 at the output of the receiver E i , which results when the racing car assigned to the relevant pair of receivers crosses the finish line. It can be seen that the voltage U 1 rises as the racing car approaches the finish line, assumes its maximum value in the finish passage z and then subsides again. On the basis of the voltage U 1 , the exact point in time of the target crossing cannot easily be determined, because the curve is too flat in the area of the maximum.
  • the voltage curve U 2 at the output of the receiver E2 is shown in Figure 2b. Since the directional characteristic of the induction loop 11 is mainly horizontal, the voltage U 2 has a first maximum 16 if the transmitter is still in front of the finish line and a second maximum 17 if the transmitter is already behind the finish line. In between there is a sharp dip 18, because if the transmitter is exactly in the vertical plane of the induction loop 11 be finds, ie above the finish line, no voltage is induced at all in the vertical induction loop 11. The voltage U 2 therefore drops sharply briefly to zero in the exact target crossing.
  • a first threshold value circuit 19 is connected downstream of the receiver E 1 .
  • a relatively high threshold value 20 is set at this.
  • the threshold value circuit 19 outputs an output signal when the voltage U 1 exceeds the threshold value 20. As FIG. 2a shows, this is the case in a certain period of time before and after the target passage z.
  • the high directional sensitivity of the vertical induction loop 11 is used to determine the exact target passage z, while the first induction loop 10 is used to delimit the larger time range in which a target passage signal 25 is possible.
  • Figure 3 shows a realization of the induction loops 10, 11. These are attached to the inner wall of a plastic tube 26, in such a way that the two induction loops 10 and 11 are perpendicular to each other.
  • the induction loops are protected from damage and deformation by the tube 26.
  • the pipe 26 can be embedded or sunk into the ground transversely to the roadway with a horizontal pipe axis.
