On base, the steering wheel of motor drives rotating disk to rotate.
4. electromagnetic valve is the Miniature push-pull DC electromagnetic valve bought, and approximates rectangular-shaped, for simple unidirectional current magnetomechanical
Structure, can realize under input pulse stretching, and then controls the keying of coin dropping channel door.Gluing is fixed on the side below base
On, all there is this electromagnetic valve at the dropping channel door of each coin, original state is " pushing away " state, and cause to fall and break a closedown.
Control line is connected to single-chip microcomputer.
5. correlation type photoelectric sensor and Hall element are purchase use.Photoelectric sensor emitter stage is fixed on rotating disk
Certain position, top, receiving pole is fixed on below rotating disk, and with emitter stage just to position, standing back is put constant, when there being coin
During by photoelectric sensor, sensor produces a signal of telecommunication pulse with certain length, and different coin dimensions are different, produce
Pulse length is the most different, can distinguish different denominations coin according to pulse length size.
6. preferably correlation type photoelectric sensor detection output pulse should be rectangle square-wave pulse, and pulse shape is similar to
One rectangle, but during in reality, photoelectric sensor is in the various interference environments in the external world, thus the pulse produced will not be reason
The rectangle square wave thought, rising edge and trailing edge non-vertical, but according to there being certain slope, and whole shared by rising edge and trailing edge
Pulse length proportion is very big, and shape is rendered as that the end is the least generally, it is the biggest trapezoidal to go to the bottom, this standard to carrying out threshold range
Really delimit and produce a very large impact, thus photoelectric sensor output signals waveform used voltage comparator to carry out whole ripple by we, will
It is trimmed to comparatively ideal rectangle square wave, makes the different coin threshold ranges of photoelectric sensor delimit more accurate.
7. Hall element needs external magnetic field, and permanent magnet can be used to produce this magnetic field, and permanent magnet is positioned under rotating disk
Certain position, side, this position is forward relative to photoelectric sensor, i.e. coin first passes through the detection of this sensor.Hall element is positioned over and turns
Above dish, position is the most right with permanent magnet center, and when coin passes through, owing to coin is magnetic material, genuine coin is hard with vacation
Coin can cause changes of magnetic field different, thus at Hall element, magnetic field intensity changes, and Hall element just produces potential change,
Just true and false coin can be picked out by detecting this change.
The operating process of said apparatus is: the machine work process is as follows:
During operation, pouring funnel into by some for different denominations coin, coin flows through funnel by the rotating disk rotated with certain speed
Take away by piece, first pass around Hall element detection.Make owing to the 5th set coin is magnetic material, there is different magnetic conductances
Rate, thus when coin is by the permanent magnet of Hall element, magnetic field can be produced the strengthening of varying strength, make at Hall element
Magnetic field changes, and produces different Hall voltages, repeats to test the Hall voltage threshold range finding true and false coin corresponding, enters
And according to this threshold range, fuzzy control just can be carried out, when coin can produce a Hall voltage value by this sensor, sentence
Disconnected its falls in genuine note threshold range or counterfeit money 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 element, if counterfeit money, is controlled after single-chip microcomputer acquisition information, logical
Crossing serial ports and show that on screen counterfeit money quantity increases by one, as shown in Figure 7, single-chip microcomputer can give the electromagnetism in duct, whereabouts, counterfeit money district
One driving pulse of valve makes it carry out " drawing " action, and carries out certain time-delay, thus counterfeit money dropping channel door can be opened and time delay
Keep certain time, when such counterfeit money is come by rotating disk band, just can be fallen into counterfeit money district by counterfeit money duct;If genuine note, coin meeting
Continuing by driven by rotary disc by correlation type photoelectric sensor detection zone, when there being coin to pass through photoelectric sensor, sensor produces
One signal of telecommunication pulse with certain length, owing to different denominations coin dimensions is different, produces pulse length the most different, according to
Test equally obtains the pulse length threshold range of different denominations coin, and then carries out fuzzy control, when coin is by this
Sensor produces a pulse length, it is judged that it falls and can distinguish different denominations coin in the threshold range of different denominations,
Equally, by serial ports, single-chip microcomputer shows that on screen unitary number of coins increases by one, various coin total amount digital displays show change,
Meanwhile, as shown in Figure 7, single-chip microcomputer also can control the electromagnetic valve action of unitary coin duct dropping door, makes coin fall into unitary
Coin zone.The separation counting of other par value coin is identical with this with Principle of identification, and so circulation work operating, just can realize continuously
The separation of coin, counting and discriminant function.
