Definitions

  • the predetermined position By a suitable choice of the predetermined position, the greater the dimensions of an article the greater is the part of its volume influencing the measuring means at the moment said part of the article, e.g. the rear edge thereof, occupies said predetermined position, so that the measurement signal then provided by said measuring means is function of the material as well as of the dimensions of the article.
  • This coin recognition system forms part of a coin controlled telephone system with a coin box (not shown) including a coin path CP (Fig. 5) which extends along three coin sensing circuits CSC1, CSC3 and CSC2 (Figs. 1 and 5) in succession and further leads to a coin collection box and to a coin refund box via deflector mechanisms (all not shown) able to be operated under the control of the system.
  • This system includes a 1 MHz clock unit CLU (Fig. 2), a signal source SS (Fig. 2), a microprocessor MP (Fig. 2), a memory comprising a data memory DMEM (Fig..3) and a programme memory (not shown), an input-output circuit IOC (Fig. 3), a control circuit CC (Fig.
  • the digital-to-analogue converter circuit DAC (Fig. 3) is an 8-bit Buffered Multiplying DAC of the type AD7523 manufactured by Analog Devices. It has data inputs Do to D7 connected to like named outputs of counter CR2 and output terminals OT1 and RFB which are internally interconnected by a suitable feedback resistance (not shown).
  • the DAC also has a reference input VREF connected to Vo, a ground input GND connected to -V1 and an output OUT2 also connected to -Vl.
  • Coin sensing circuit CSC3 (Fig. 1) with input terminal I3 and output terminal 03 includes a cylindrical sensing coil L5 (Fig. 5) mounted along the above mentioned coin path CP and between , CSCl and CSC2.
  • CSC3 is however so close to CSC2 that even a coin with the smallest diameter able to be processed by the system is simultaneously sensed by CSC2 and CSC3 at least during a certain time interval.
  • Cylindrical coil L5 has a diameter which is considerably smaller than that of coils Ll to L4 in order that the variation of the output signal at terminal 03 should be relatively abrupt. Because of the use of such a small diameter coil L5 a higher frequency f3 is required to obtain a suitable output voltage signal.
  • junction point 05 of d2 and R10 is connected to the like named input 05 of an OR-gate OR (Fig. 3) the other input of which is connected to the output C03 of the microprocessor MP.
  • the output CL of OR-gate OR is connected to the like named clock input CL of the input/output circuit IOC.
  • the junction point of d2 and R10 is considered to be activated and de-activated when its voltage is larger and smaller than respectively.
  • a coin such as CN (Fig. 5)
  • it first passes between the sensing coils Ll and L2 of the transformer Tr of coin sensing circuit CSC1 due to which the amplitude of the sinusoidal voltage signal normally varying between a minimum value slightly smaller than -2V1 + Vo and a maximum value slightly larger than Vo gradually decreases towards a minimum value and afterwards again gradually increases.
  • Fig. 4 wherein two different time scales are used in the left and right hand parts of the drawing. More particularly when a coin is present the amplitude of this reduced signal becomes larger than -2V1 + Vo for a time interval much larger than the above mentioned predetermined time interval Tl.
  • this counter CR1 then counts the pulses of the square pulse waveform at frequency f2 applied to its clock input C I, and at its output D2 it generates a pulse waveform of frequency fl which is applied to counter CR2.
  • the above mentioned threshold voltage E which substantially linearly increases from about -2V1 towards -Vl with a speed depending on the period of fl, this period being equal to 64 microseconds. This voltage is applied to the inverting input of comparator COR1.
  • the microprocessor MP grants a request (de-activation of interrupt input INT) for a clock interrupt programme it activates its control output C04, due to which counter CR3 is then reset by the activation of its reset input RS.
  • the processor MP then also substracts a unit from a value stored in a counter word CR of the memory MEM, this value being at most equal to Np (Fig. 6).
  • Np Fig. 6
  • the microprocessor MP has finished a clock level programme it resumes the interrupted task level programme and after having executed this programme it executes the monitor programme. Under the control of this programme the value stored in the counter word CR is made equal to the maximum value Np. The latter value has been so chosen that taking the interrupts into account the resultant value stored in the counter word CR never becomes zero under normal operating conditions.
