Breaking, it falls in the interior still counterfeit money threshold range of genuine note threshold range, that is, tells the true and false of coin,
If it is counterfeit money, single-chip microcontroller is controlled after obtaining information, is just fallen by counterfeit money duct when counterfeit money is come by turntable band
Enter counterfeit money area；
If it is genuine note, coin will continue to be detected by driven by rotary disc by photoelectric sensor, when there is coin to pass through photoelectric transfer
When sensor, judges that it falls in the threshold range of different denominations and distinguish different denominations coin, single-chip microcontroller controls different denominations
Coin enter and its corresponding region and count, various coin total amount digital displays show variation, and such cycle operation operates, just continuously
Realize separation, counting and the discriminant function of coin.
Specifically, the present invention includes one, special funnel, and turntable one, pedestal one, Cortex-M4 K60 monolithic
Machine, the 24V DC servo motor of DIY one, correlation type photoelectric sensor, Hall sensor.
1. funnel is special component, unlike the funnel of conical surface in traditional impression, the bucket of the funnel is as non-
Conical surface, from the point of view of overlooking from the top down, shape is approximately oval；The neck of funnel is rendered as 45 degree of oblique angles (referring to attached
Fig. 1 and 2), the interior circular diameter of neck can guarantee that unitary coin smoothly slides, 2 millimeters bigger than unitary coin diameter.Funnel and pedestal
It is joined by gluing, funnel is located on pedestal disk, and there are the glued mating surfaces with funnel fan-shaped surface for disk edge.It is (attached
Fig. 2)
2. turntable is a round turntable (referring to attached drawing 3), there are the Photoelectric Detection hole of sensor, features on turntable
It is that detection hole profile is to carry out Boolean add operation by three circles to obtain, centre is 2 millimeters one bigger than unitary coin diameter
Circular hole, narrowing toward each end Circularhole diameter is macropore radius, and the aperture center of circle is located on macropore justifies, all Photoelectric Detection holes circumferentially array
Distribution.Turntable is placed on pedestal, between funnel and pedestal, is bolted by four in motor steering wheel, is driven by a motor
Turntable rotation.
3. motor is the direct current 24V servo motor of DIY, approximate rectangular shape is installed on pedestal lower part, is screwed
In on pedestal, the steering wheel of motor drives turntable rotation.
4. solenoid valve is the Miniature push-pull DC electromagnetic valve of purchase, approximate rectangular-shape is simple direct current magnetomechanical
Opening and closing that is flexible, and then controlling coin dropping channel door can be achieved under input pulse for structure.Gluing is fixed on the side below pedestal
On, there is the solenoid valve at the dropping channel door of each coin, original state is " pushing away " state, and cause to fall and break a closing.
Control line is connected to single-chip microcontroller.
5. correlation type photoelectric sensor and Hall sensor are that purchase uses.Photoelectric sensor emitter is fixed on turntable
Top position, receiving pole are fixed below turntable, and emitter face position, standing back set it is constant, when there is coin
When passing through photoelectric sensor, sensor generates the electric signal pulse with certain length, and different coin dimensions are different, generates
Pulse length is also different, can distinguish different denominations coin according to pulse length size.
6. ideal correlation type photoelectric sensor detection output pulse should be rectangle square-wave pulse, pulse shape is similar to
One rectangle, but photoelectric sensor is in the various interference environments in the external world in reality, thus the pulse generated will not be reason
The rectangle square wave thought, rising edge and failing edge are non-vertical, but entire according to there is certain slope, and shared by rising edge and failing edge
Pulse length specific gravity is very big, and shape is generally rendered as that bottom very little, bottom are very big trapezoidal, this is to the standard for carrying out threshold range
It really delimit and produce a very large impact, thus we carry out whole wave using voltage comparator to photoelectric sensor output signals waveform, it will
It is trimmed to comparatively ideal rectangle square wave, delimits the different coin threshold ranges of photoelectric sensor more accurate.
7. Hall sensor needs external magnetic field, usable permanent magnet generates the magnetic field, and permanent magnet is placed under turntable
Certain position of side, the position is forward relative to photoelectric sensor, i.e., coin first passes through sensor detection.Hall element, which is placed in, to be turned
Above disk, position and permanent magnet center face, when coin passes through, since coin is magnetic material, genuine coin is hard with vacation
It is different that coin can cause changes of magnetic field, thus magnetic field strength changes at Hall element, and potential change is just generated on Hall element,
True and false coin can be identified by detecting this variation.
The operating process of above-mentioned apparatus are as follows: the machine course of work is as follows:
When operation, funnel is poured by different denominations coin is several, and coin flows through funnel by the turntable that rotates with certain speed
It is taken away by piece, first passes around Hall sensor detection.Since the 5th set of coin is that magnetic material is made, there is different magnetic conductances
Rate, thus when coin passes through the permanent magnet of Hall sensor, the reinforcing of varying strength can be generated to magnetic field, made at Hall element
Magnetic field changes, and generates different Hall voltages, repeats test and finds the corresponding Hall voltage threshold range of true and false coin, into
And according to this threshold range, fuzzy control can be carried out, a Hall voltage value can be generated when coin passes through this sensor, is sentenced
Breaking, it falls in the interior still counterfeit money threshold range of genuine note threshold range, can tell the true and false of coin.It is now assumed that there is one piece of unitary
Coin is moved by driven by rotary disc, is detected by Hall sensor, and if it is counterfeit money, single-chip microcontroller is controlled after obtaining information, is led to
It crosses serial ports and shows that counterfeit money quantity increases by one on the screen, as shown in Fig. 7, single-chip microcontroller can give the electromagnetism in counterfeit money area whereabouts duct
One driving pulse of valve makes it carry out " drawing " movement, and carries out certain time-delay, thus counterfeit money dropping channel door can be opened and is delayed
Certain time is kept, counterfeit money area can be fallen into when such counterfeit money is come by turntable band by counterfeit money duct；If it is genuine note, coin meeting
Continue by driven by rotary disc through correlation type photoelectric sensor detection zone, when there is coin to pass through photoelectric sensor, sensor is generated
One electric signal pulse with certain length, since different denominations coin dimensions are different, generation pulse length is also different, according to
Test can equally obtain the pulse length threshold range of different denominations coin, and then carry out fuzzy control, when coin passes through this
Sensor generates a pulse length, and different denominations coin can be distinguished by judging that it falls in the threshold range of different denominations,
Equally, single-chip microcontroller shows that unitary number of coins increases by one by serial ports on the screen, and various coin total amount digital displays show variation,
Meanwhile as shown in Fig. 7, single-chip microcontroller can also control the electromagnetism valve events of unitary coin duct dropping door, and coin is made to fall into unitary
Coin zone.Separation counting and the Principle of identification of other par value coins are identical with this, and such cycle operation operating can be realized continuously
Separation, counting and the discriminant function of coin.
