Specific embodiment
A kind of banknote of present invention offer is soft, hard magnetic anti-counterfeiting characteristic identifying system, to make the purpose of the present invention, technical scheme
And effect is clearer, clear and definite, below the present invention is described in more detail.It should be appreciated that described herein be embodied as
Example is not intended to limit the present invention only to explain the present invention.
Refer to Fig. 1, its be the present invention banknote is soft, hard magnetic anti-counterfeiting characteristic identifying system structured flowchart.As schemed
Show, the banknote is soft, hard magnetic anti-counterfeiting characteristic identifying system includes：Currency examination magnetic head 100, control circuit（210 to 250, meeting below
Describe in detail）And Zou Chao mechanisms（310 to 320, can describe in detail below）；Wherein, the currency examination magnetic head 100 sets
Put in the lower section of Zou Chao mechanisms, and the currency examination magnetic head is connected with control circuit, it is special for reading the soft, hard magnetic on banknote
Anti-counterfeiting information is levied, and two kinds of magnetic characteristic anti-counterfeiting information identifications are separated.
Specifically, in the present embodiment, the Zou Chao mechanisms include a money pressing wheel 310 and an infrared tube 320.When testing
When paper money machine works, banknote 10 is against currency examination work surface and is travelled forward by money pressing wheel 310.Banknote 10 is reached letter by infrared tube 320
Number pass to control circuit.The currency examination magnetic head 100 in the present embodiment, is also adopted by a special currency examination magnetic head, and it includes a screen
Cover shell（Generally rectangle）, it is provided with operation window along the length direction of shielding case and to be disposed with inside it several only
Vertical detector unit.
Please continue to refer to Fig. 2 a and Fig. 2 b, the banknote that it is respectively the present invention is soft, hard magnetic anti-counterfeiting characteristic identifying system
Horizontal, the longitudinal sectional view of currency examination magnetic head in embodiment.As illustrated, the detector unit 110 is successively by binding post 111, line
Frame 112, coil 113, bearing 114, magnetic core 115, middle magnetic sheet 116 and spacer shims 117 are constituted；
Magnetic sheet 116 is constituted during each detector unit 110 shares one piece by two groups of coils 113, magnetic core 115 and spacer shims 117
Symmetrical double magnetic loop, clips spacer shims 117 and forms gathering throat, for reading banknote between magnetic core 115 and middle magnetic sheet 116
Magnetic information；The gathering throat stretches out the operation window of shielding case 120, and coil 113, coil 113 are wound with coil holder 112
Two ends connect terminal 111 respectively, the bottom of shielding case 120 is provided with bonnet 121, and the binding post 111 is used for through bonnet 121
The signal that output is read.In the present embodiment, the number of the detector unit is 16, and 16 detector units constitute effective magnetic core
Reading length is 189mm, can contain banknote most long in the world.
The control circuit includes：CPU（Central processing unit, in the present embodiment, it adopts single-chip microcomputer）210th, magnetic head letter
Number amplify electronic circuit 220, DC source 230 and electrical switch 240.The CPU210 is connected to currency examination by electrical switch 240
Magnetic head 100, separately leads up to magnetic head signal amplification electronic circuit 220 and is connected to currency examination magnetic head 100；The DC source 230 and electricity
Son switch 240 is connected.The control circuit its can only read Hard Magnetic when DC source is not added with and can not read soft magnetism；Plus during DC source
Can read to be realized the characteristics of Hard Magnetic can read soft magnetism again that system is soft to banknote, the identification of hard magnetic anti-counterfeiting characteristic.
Its workflow is as follows（As a example by 100 yuans）：When cash inspecting machine works, money pressing wheel 310 pastes banknote 10
The work surface of currency examination magnetic head 100 to travel forward.The arriving signal of banknote 10 is passed to CPU210, CPU210 controls by infrared tube 320
Electrical switch 240 disconnects, and currency examination magnetic head 100 is not added with DC source（DC source 230 is disconnected）, on 100 yuans of banknotes
Serial number and safety line in hard magnetic material carry remanent magnetism, the magnetic line of force of these remanent magnetism is by detector unit in currency examination magnetic head 100
The magnetic loop short circuit being made up of coil 113, magnetic core 115, middle magnetic sheet 116 and spacer shims 117, causes the magnetic flux quantitative change in loop
Change, thus coil 113 produces faradism physical features output corresponding signal, signal Jing magnetic head signals amplify electronic circuit 220 and form waveform
It is sent to CPU210 and is compared discriminating；Simultaneously because the soft magnetic materials on the Great Hall of the People pattern on banknote is without remanent magnetism, nothing
The magnetic line of force, the magnetic flux in the magnetic loop of currency examination magnetic head 100 does not change, and coil 113 does not produce faradism physical features, currency examination magnetic head
100 no signals are exported.CPU210 judges banknote with the phase of currency examination magnetic head 100 according to infrared tube 320 and the tach signal of money pressing wheel 310
To position, output switch pulse electron switchs 240, and now electrical switch 240 is connected（DC source 230 is connected）, currency examination magnetic
100 added with DC source, and the interior loop of currency examination magnetic head 100 produces the constant magnetic line of force by magnetic core loop, produces at gathering throat
Raw stationary magnetic field, the stationary magnetic field magnetizes to the soft magnetic materials on the Great Hall of the People pattern on banknote, makes soft magnetic materials
With remanent magnetism, as banknote is moved, the magnetic line of force of these remanent magnetism causes the magnetic flux change in magnetic head loop, and coil 113 is thus
Faradism physical features output corresponding signal is produced, the signal Jing magnetic head signals amplification formation waveform of electronic circuit 220 is sent to CPU210 to be carried out
Relatively differentiate.
Further, the control circuit can also include a display device 250 being connected with CPU210, and it is used to reflect
Other result shows.
In sum, the invention provides a kind of banknote is soft, hard magnetic anti-counterfeiting characteristic identifying system, it includes：Currency examination magnetic
Head, control circuit and Zou Chao mechanisms；Wherein, the currency examination magnetic head is arranged on the lower section of Zou Chao mechanisms, and the currency examination magnetic head
It is connected with control circuit, for reading soft, hard magnetic feature anti-counterfeiting information on banknote, and by the false proof letter of two kinds of magnetic characteristics
Breath identification separates.The banknote is soft, hard magnetic anti-counterfeiting characteristic identifying system has can only read Hard Magnetic not when DC source is not added with
Soft magnetism can be read；Plus the characteristics of during DC source can read Hard Magnetic and can read soft magnetism again.It is soft, hard on banknote so as to read completely
Magnetic characteristic anti-counterfeiting information, and two kinds of magnetic information identifications are separated.It greatly improves the cash inspecting machine and recognizes the true, false distinguishing of counterfeit money
Ability, reaches currency examination technical field advanced level, with good popularizing application prospect.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, and for those of ordinary skills, can
To be improved according to the above description or be converted, all these modifications and variations should all belong to the guarantor of claims of the present invention
Shield scope.
