Definitions

  • the inventions relate to circuit arrangements in coin validators according to the preambles of claims 1 and 2.
  • Circuit arrangements of the type mentioned in the preamble of claim 1 which accept a coin when this causes the oscillator vibrations to be suspended, as well as those which accept a coin when it initiates the vibrations.
  • the circuit arrangement according to the preamble of claim 2 basically works according to the same test principle as the former, in that the reduction in the oscillation amplitude caused by influencing the magnetic field (or electrical field) also serves as the test criterion. Instead of entering the field of the self-induction coil of the oscillator, the coin enters the coupling field between a primary and a secondary coupling element, a coin acceptance signal depending on the reduction in the degree of coupling caused by the coin, i.e. depending on the reduction in the amplitude of the received signal.
  • the aim of every coin check is to differentiate between acceptable coins and unacceptable ones as precisely as possible.
  • the damping limit of the oscillator which is decisive for the test and at which the vibrations cease, is set exactly according to the lower limit of the conductivity range of acceptable coins. So far, this has not been done, but rather a relatively large tolerance range has been specified. That was necessary because of the boundary conditions.
  • the oscillator oscillations start or stop, depending on the temperature and other influences.
  • the temperature e.g. the resistance of the winding of the oscillator coil and the amplification of transistors; further influence e.g. Metal residues in the dirty coin channel, the coil field and thus the damping.
  • the object of the invention is to restrict the test tolerance range more precisely to the permissible tolerance range of acceptable coins and to avoid additional tolerances for temperature fluctuations and other influences.
  • Gain values are stored as gain values, for example the value of a control voltage regulating the gain or the degree of negative feedback or feedback or the values of the resistors which control voltage , affect the degree of negative feedback or the degree of feedback. Preferred embodiments are described in claims 3 to 9.
  • the normal value of the amplification indicates the amplification at which the oscillator vibrations under normal conditions start or stop when there is no coin in the coil field.
  • the resonant circuit can either be damped by its own damping or additionally by switching on a resistor according to claim 3, which is not switched on during the coin check.
  • the resistance is dimensioned in such a way that it effects at least approximately the same damping of the resonant circuit as an acceptable coin. If several types of coins are to be tested, the resistance is expediently dimensioned such that the damping caused by it lies approximately in the middle of the damping range given by the coins of the different types of coins.
  • the normal value of the amplification and the value of the amplification determined before each coin check under the prevailing conditions are determined for a damping of the resonant circuit, which corresponds approximately to the damping of the resonant circuit caused by the acceptable coins.
  • setpoint limits of the gain corresponding to the prevailing conditions are obtained even if the relative damping change caused by operating conditions deviating from the normal conditions is not independent of the total damping.
  • the output 1 of an operational amplifier 2 is connected to its feedback input 3 by a feedback path 4 and 5, to which an oscillating circuit 6, 7 is connected.
  • a coin channel (not shown) leads through the field of the resonant circuit coil i.
  • At a negative feedback input 8 of the operational amplifier 2 is part of the output voltage of the same, which is tapped at a voltage divider.
  • the voltage divider consists of a fixed resistor 9 connected between the output 1 and the input 8 and one or more of the resistors 11 to 18 which can be switched into the voltage divider by applying one or more of the switching transistors 21 to 28.
  • the resistance value of the voltage divider partial resistor 11 to 18, at which the negative feedback voltage is tapped, can be changed in 255 steps.
  • the switching transistors 21 to 28 can be acted upon individually and in combinations by a program control device 29, as a result of which 255 different degrees of negative feedback can be set.
  • the relevant part of the program is - as described in more detail below - so that all 255 or selected gain precisely in increasing (or decreasing) order one after the other.
  • a comparator 30 compares the output signal of the amplifier 2 with a reference voltage at the output 31 of a voltage stabilizer 32.
  • the reactance of a capacitor 33 connected between the resistor 9 and the resistors 11 to 18 g is small compared to a discharge resistor 34 connected in parallel.
  • a calibration resistor 35 can be connected in parallel to the resonant circuit capacitor 7 by means of a transistor 36.
  • the resistor 35 when it is connected in parallel to the resonant circuit 6, 7 by the application of the transistor 36, has the same effect as a coin 37 of a certain acceptable type in the coil field 6 Resonant circuit, based on the damping range given by all coins.
  • the resistor 35 is small compared to a resistor 38, via which the stabilized DC voltage at the output 31 is led to the amplifier input 3.
  • the program control device 29 has a memory 39 with two memory parts, namely a read-only memory 49 (ROM or REPROM) and a read / write memory 59 (RAM), and an arithmetic logic unit 69.
  • ROM read-only memory
  • RAM read / write memory
  • a normal value of the gain and two predetermined normal limit values of the gain are stored in the read-only memory 49 for each acceptable coin type.
  • the gain values are the resistance values of the voltage divider part which determine the gain standes 11 - 18, at which the negative feedback voltage is tapped, stored.
  • the storage takes place in each case together with a code word which specifies which of the transistors 21 to 28 is conductive and which are not conductive.
  • the normal value of the gain is determined under normal conditions (temperature, operating voltage) and without a coin in the field da * coil 6, as follows: First, the resistor 35 is connected in parallel to the resonant circuit 6, 7 by applying the transistor 36. The program controller 29 then acts on the transistors 21 to 28 in such a way that the partial resistor 11 to 18 is gradually increased starting with the smallest of the 255 resistance values (all the transistors 11-18 are applied). At the lowest resistance value, the negative feedback is minimal. the gain is maximum and the oscillator 2, 6, 7 oscillates. The comparator 30 supplies pulses to the program control 29 in time with the upper half-wave of the oscillator oscillations.
  • two normal limit values for the gain are stored in the read-only memory 49 for each acceptable coin type. These are determined in a similar way to the normal value of the gain: first, the transistor 36 is blocked, so that the resistor 35 is not connected to the resonant circuit 6, 7. A coin of the acceptable type is then brought into the field of the coil 6. Under normal conditions, the partial resistance 11 to 18 is then gradually increased in the same way as in the determination of the normal value of the amplification until the resistance level is reached at which the oscillator vibrations cease. Two values of the partial resistance are then stored in the read-only memory 49 as normal limit values for the amplification, one of which is smaller by a tolerance and the other of which is greater than the resistance of the resistance level reached.
  • the tolerances are measured according to the allowable tolerance range of acceptable coins of the type concerned for strict testing.
  • the normal limit values of the amplification can also be determined by placing a coin representing the lower and an upper limit of the tolerance range of the coin type in the field of the coil 6 and determining the resistance value of the partial resistor 11 to 18, at which the oscillator vibrations stop.
  • the circuit arrangement is put into operation by a signal from a coin detector (not shown) arranged at the entrance of the coin channel.
  • the program controller 29 acts on the transistor 36, which connects the resistor 35 in parallel with the resonant circuit 6, 7.
  • the program controller 29 then initiates the operations described below of a first program part, which are ended before the inserted coin enters the field of the coil 6: the partial resistor 11 to 18 is gradually increased starting with the smallest resistance value until the resistance level is reached at which the oscillator vibrations stop. If conditions other than normal prevail, the value of the partial resistor 11 to 18 corresponding to this stage is not equal to the normal value stored in the read-only memory 49. Rather, there is a deviation.
  • the arithmetic unit 69 determines the ratio of this value of the partial resistance to the normal value and multiplies the upper and lower normal limit values of the individual coin types stored in the read-only memory 49 by this ratio. As a result, relevant upper and lower limit values for coin acceptance are obtained under the prevailing conditions. For each upper limit value obtained in this way, the next resistance level above it, for each lower level the next resistance level below it, is stored in RAM memory 59 as upper and lower target limit values for the coin type in question for coin testing. The transistor 36 is then blocked. This concludes the first part of the program.
  • the coin belongs to an acceptable coin type if the oscillator 2, 6, 7 oscillates at the lower target limit value of a coin type and does not oscillate at the upper target limit value of the same coin type.
  • the lower target limit is the smaller resistance value, it causes a greater degree of amplification.
  • the coin belongs to an acceptable coin type if the resistance level at which the oscillator vibrations are between the lower and upper target limit of a coin type.
  • test in case a) has the advantage that it takes place much faster than in case b).
  • the oscillator 2, 6, 7 oscillates in the idle state and the partial resistance 11 to 18 is increased in stages.
  • the oscillator could not oscillate in the idle state and the partial resistance, starting with the largest resistance value (or the largest stored target limit value), could be gradually reduced until the resistance level at which the oscillator vibrations set in is reached. The gain would not be gradually reduced, but rather increased.
  • the circuit arrangement according to FIG. 2 differs from that according to FIG. 1 by the circuit part drawn over the dash-dotted line.
  • the feedback path 4, 5 is omitted and the operational amplifier 2 is inductively coupled to the coil 42 of an AC generator (or oscillator) 43, which forms a primary coupling element, by a coil 41 forming a secondary coupling element.
  • the coin 37 gets into the coupling field between the two coils 41, 42 and changes the degree of coupling.
  • the transmitted signal passes through a capacitor 44 to the amplifier input 3.
  • the comparator 30 compares the amplitude of the output signal of the amplifier 2 with the reference voltage at the output 31 and emits signals to the program controller 29 in time with the upper half-wave of the transmitted and amplified AC signal until the signal amplitude with a corresponding reduction in the degree of coupling falls below the reference voltage. Otherwise, the circuit arrangement according to FIG. 2 operates in accordance with the circuit arrangement according to FIG. 1: A normal value of the gain is likewise stored in the read-only memory 49.
  • partial resistor 11 to 18 is gradually increased starting with the smallest resistance value until the resistance level and thus the amplification level is reached, at which the amplitude of the output signal of amplifier 2 is equal to that Comparison voltage at the output 31 is or falls below this.
  • the resistance value of the resistance level reached is then stored as the normal value of the amplification.
  • the coin check is then also analogous to that described above, in that the program controller 29 gradually increases the partial resistance 11 to 18 before the coin check until the output signal amplitude of the amplifier 2 assumes or falls below the reference voltage.
  • the arithmetic unit 69 then multiplies the quotient from the value of the partial resistance 11 to 18 thus obtained and the normal value by the lower and upper normal limit values stored in the read-only memory 49 for each coin type. For each lower and upper limit value calculated in this way, the next resistance level below and above it is stored in RAM memory 59 as the lower and upper target limit value of the coin type in question. During coin testing, the partial resistance 11 to 18 is then also gradually increased.
  • a coin acceptance signal is emitted if the output signal amplitude of the amplifier 2 assumes the comparison voltage at the output 31 when the value of the resistance level reached lies between the two target limit values. If only the target limit values of the resistance levels stored in the RAM memory 59 are run through from bottom to top, a coin acceptance signal is emitted if the amplitude of the amplifier output signal exceeds the reference voltage for the smaller of the two resistance target limit values of a coin type and falls below it for the larger one. Of course the partial resistance could also be gradually reduced starting with the greatest resistance value.
  • the accuracy of the coin check in the described embodiments does not depend on any external influences, it is only limited by the number of gain values that can be set by the resistors 11 to 18. A slight increase in the number of resistors 11 to 18 (and the corresponding switching transistors 21 - 28) results in a considerable increase in the adjustable gain values and thus in the accuracy.
  • the resistors 11 to 18 could of course also be connected to the feedback path of the oscillator instead of to the negative feedback path.
  • the advantage of the arrangement in the negative feedback path is that the quality of the resonant circuit is not influenced, which is essential for an accurate, selective coin check.
  • the gain could be controlled by capacitors instead of resistors 11 to 18.
  • an oscillator circuit with two coupled oscillating circuits could also be provided, in the coupling field of which the coin arrives.
  • the circuit could also be designed so that the oscillator vibrations begin when an acceptable coin gets into the coil field.
  • the first part of the program described in connection with FIG. 1 can be shortened by gradually increasing the partial resistance 11 to 18 instead of the smallest resistance value with a larger resistance value, which is chosen so that the oscillator vibrations even under the most extreme conditions (temperature. not heavily soiled coin channel).
  • predetermined normal limit values and a predetermined normal value of the gain can be stored in the ROMs 49 during the manufacture of the coin validators for the entire series of coin validators.
  • the value of the partial resistor 11 to 18 is determined in the manner described there, at which the oscillator oscillations cease when the resistor 35 is connected in parallel to the resonant circuit 6, 7 and no coin in the coil field 6 is.
  • the arithmetic logic unit 69 only determines the difference between this value and the predetermined normal value stored in the ROM 49 and stores this difference as a correction value in the RAM 59 successively all setpoint limit values, in each case by adding to the predetermined normal limit values stored in the ROM 49 RAM 59 stored correction value added.
  • the corresponding resistance level 11 to 18 is set and it is determined in the manner described above whether the oscillator vibrations stop.
