Definitions

  • the invention relates to a method for setting the Scanning range of vehicle-operated measuring devices, such as e.g. of hot runner location devices, in which a wheel sensor via a transmitter and two arranged on both sides of the transmitter Receiver has the signals of both receivers compared with each other and depending on the result of the Signal comparison a measurement is made as well as on a Device for setting and adjusting measuring devices Track paths relative to wheel sensors, with a base plate on which the wheel sensors are fixed and the measuring devices can be fixed in geometrically defined Distance to each other, the wheel sensors each have a transmitter coil and two assigned receiver coils.
  • vehicle-operated measuring devices such as e.g. of hot runner location devices
  • Wheel sensor elements By being arranged on both sides of a rail head Wheel sensor elements is an arrangement of the hot runner location system in a position in which the wheel sensors also exactly Determine the overflow of a wheel, not for spatial reasons possible.
  • Wheel sensors have already become known from EP-A 340 660, which are characterized by the fact that they are only to one side of the rail head of a rail can be arranged.
  • the wheel sensors that can be removed from this EP-A 340 660 consist for example on an inside of a rail of the Track-mounted coil system with an AC-powered Transmitter coil and two assigned receiver coils.
  • the transmitter coils induce an induction voltage in the receiver coils. If there is a receiver coil in front of and behind the transmitter coil is arranged in the longitudinal direction of the rail, can for example, if the receiver coils are identical are and arranged at the same distance from the transmitter coil are identical in both receiver coils is induced to conclude that at this time a wheel runs in the middle above the sensor.
  • EP-A 340 660 An electric one Evaluation of signals from such sensors is in EP-A 340 660 has already been proposed and it will be used with such a signal intersection evaluating circuit the exact location of the wheel center or the wheel axis.
  • the hot runner location system can also be the location of the wheel be adjusted precisely, in particular by the fact that for one such sensor only for one side of the rail track the arrangement of the required sensor elements is required, an exact geometric correlation can also be maintained can.
  • the invention now aims at a method of the beginning to create the type mentioned, with which given a given geometric Arrangement of the individual components for vehicle-operated Measuring devices, such as hot runner location devices in particular, also after the completion of all mechanical adjustment work a fine adjustment is made possible without that this is an increase in the construction of the facilities for determining the parts of such a vehicle-operated Measurement device results.
  • a simple mechanical fixation of the parts found enough be and still an adjustability later still be possible.
  • the method according to the invention exists to achieve this object essentially in that to or from at least one of the signals the receiver of a wheel sensor an adjustable, constant Signal is added or subtracted electrically, and that the Measurement depending on the evaluation of the comparison of the received signals of the receiver of the wheel sensor becomes. Because now at least one of the signals of the receiver an adjustable constant signal electrically from a wheel sensor is added or subtracted, the EP-A 340 660 outlined procedure for determining a Change signal intersection so that this intersection can be moved. For example, through addition of an electrical signal changed signal one of the two Receiver coils lead to a shift of the intersection the voltage curves of the two receiver coils, resulting in a electrical fine adjustment of the intersection is made possible.
  • the shift of the intersection by the electrical Addition or subtraction of a DC component has to Consequence that, for example, a gate opening or gate closing time can be moved accordingly.
  • a gate opening or gate closing time can be moved accordingly.
  • the gate can be moved altogether or the Regulate the door width, which makes a high degree of adjustability possible given is.
  • the inventive device for setting and adjusting of measuring devices on track paths relative to wheel sensors with a base plate on which the wheel sensors are fixed and the Measuring devices can be determined at a geometrically defined distance from each other, wherein the wheel sensors each have a transmitter coil and two assigned Have receiver coils is characterized in that that at least one voltage signal from a receiver coil is supplied to a computing circuit, which has a modified signal of the Voltage signal of the receiver coil forms, and that the output signal the arithmetic circuit and the voltage signal of the second receiver coil is fed to a comparator, the Output signal can be connected to the measuring device.
  • the arithmetic circuit becomes a modified signal Receiver coil formed and when compared to the induced Voltage in the second receiver coil will shift the parameters relevant for the evaluation, e.g. of the intersection of the two signal curves for a given correlation or identity of the two signals.
  • a simple arithmetic circuit is sufficient, whereby the training is made in a particularly simple manner, that the arithmetic circuit is designed as an addition circuit and adds an adjustable voltage value to the input signal or subtracted and / or as a multiplication or quotient circuit is formed, and with an adjustable factor multiplied or divided by this.
  • An adjustable Voltage signal can be obtained simply by conventional means Circuits can be achieved.
  • the device can be designed so that the arithmetic circuit an operational amplifier contains the inputs Signal of a receiver coil and a voltage source with adjustable Voltage is connected.
  • FIG. 1 shows a schematic representation of an arrangement a vehicle-operated measuring device in the longitudinal direction of the rail seen, the rail is shown in section
  • Fig. 2 shows a plan view of a measuring device
  • FIG. 3 a detailed view of a wheel sensor from the inside of the track Seen here
  • Fig. 4 shows the waveform as it with the wheel sensor 3 can be obtained without modification of the signals
  • 5 shows the signal curve after electrical fine adjustment or Modification of the signals as originally received and are shown in Fig. 4.
  • Fig. 1 denotes a rail, the rail foot is connected to a mounting plate 2.
  • a wheel sensor 3 is arranged on the track.
  • the construction of the The wheel sensor is selected so that it is on one side of the web the rail 1 is arranged so that to the other side of the web a hot runner location device 4 can be arranged.
  • a wheel sensor 3 is shown schematically on the rail Wheel 5 can be seen, the axle journal 6 in the scanning area 7 the hot runner location system 4 arrives. Analog can over a further scanning range, the bearing temperature of the bearing 8 is also sampled will.
  • a wheel sensor 3 comprises a central one Transmitter coil 11, being on both sides in the longitudinal direction of the rail offset, receiver coils 12 and 13 are arranged.
  • the coil axes are here, as detailed in EP-A 340 660 set out, directed at the rail foot, which therefore as damping metal surface in the effective area under the receiver coils 12 and 13 lies.
  • the axes are in the correct arrangement past the rail head and are against the possible Passage area of the wheel rim of this wheel 5 directed. As long as there is no wheel 5 in the effective range, enter two receiver coils 12 and 13 the largest possible output signals on.
  • a new switching threshold can be set exactly and ⁇ t depending on ⁇ u, i.e. dependent on adjust the added voltage within wide limits and adjust.
