专利摘要:
A method and an apparatus for testing and identifying electrically conductive coins and similar. According to the method, the effect of each coin 1 to be tested and identified on a magnetic field, generated by means of coils 101, 201, is measured and compared with a reference value such that a coin is accepted if the measured value is close enough to the reference value. This reference value is determined on the basis of the effect produced by a preselected reference coin 2 on a reference magnetic field generated by coils 102, 201 having the same magnitude as the measurement magnetic field. <IMAGE>

(5) COIN RECOGNITION DEVICE
one
i The invention relates to monitoring devices; coins and their equivalents and can be used in banking.
A device for sorting coins is known, comprising a housing in which a coin duct, a current generator, inductors and measuring unit 1 are placed.
A disadvantage of the known device is the relatively low reliability due to the influence of external factors on the parameters of the inductors and the measuring unit.
The closest in technical essence to the present invention is a device for detecting mo-: no and their equivalents, containing Kojanyc, in which is placed the coin duct, current generator, excitation element of measuring magnetic field, comparison element of reference and measuring magnetic fields, measuring block C21. AND THEIR EQUIVALENTS
A disadvantage of this device is the relatively low reliability due to the disconnection of the exciting, sensing and measuring circuits.
The purpose of the invention is to increase reliability.
The goal is achieved by the fact that in the device for recognition
10 coins and their equivalents, comprising a case in which a coin-carrier, a current generator, a field of a reference magnetic field, an element of a measuring magnetic field, a reference element of a reference and measuring magnetic field, a meter are placed. unit, the excitation element of this magnetic field is made in
20 as an exciting inductive coil with a chamber for accommodating a reference coin and a receiving inductive coil, the excitation element of the measuring magnetic field is more in the form of an exciting inductive
NOI coils with a cavity connected by means of a coin duct to a coin acceptor inlet, and a receiving coil, exciting and perceiving inductive coils are connected to a bridge circuit connected to the current generator and coe.t connected to the measuring unit.
In addition, in the device, the exciting and perceiving inductive coils are made in the form of one partitioned coil with corresponding taps from each section according to the number of coins to be tested.
FIG. 1 is a block diagram of the device; in fig. 2-bridge scheme of one section; in fig. 3 is a bridge circuit for several sections;
in fig. - coin channel; on Fig.5 the location of the coins in the section.
The device comprises a housing 1, a coin duct 2, inlets 3, a current generator k, an excitation element 5 of a reference magnetic field, an excitation element 6 of a measuring magnetic field, a comparison element 7 measuring unit 8, a reference coin 9, a branded coin 10, a chamber 11, a cavity 12 .
The device works as follows. About
A recognizable coin 10 enters the coin duct 2 through the inlet 3, which is fixed in cavity 12. A current generator A supplies the excitation element 5 of the reference magnetic field and the excitation element 6 of the measuring magnetic field, which are made in the form of inductive coils included in a bridge circuit connected to to the measuring unit 8. In accordance with the recognizable coin 10 with the reference value in the comparison element 7, the resulting magnetic field ooTBetcTByeT with the reference value (zero or maximum) and at the input will measure The target unit 8 is given an electrical signal that the recognized coin 10 is consistent with the nominal value.
If the recognized coin 10 does not match the nominal value, an electrical signal corresponding to the rejected coin is supplied to the input of the measuring unit 8.
The device can recognize all the coins for which this one exists.
the lone coins and for which the measuring unit is set up 8.
The device is highly reliable, since the comparison of a recognizable coin takes place directly from the reference coin under identical conditions. -
The device is quite easily reconstructed for any kind of coin recognition by installing one or several reference coins.
