Referring to Fig. 2, the embodiment of the present application provides a kind of paper money safety line detection method, the bank note safety line detection side
Method is applied to detection device, which includes：Step S100, step S200 and step S300.
Step S100：During the non magnetic safety line based on eddy current detection bank note to be measured, obtain described non-magnetic
The high low signature of property safety line.
When needing to carry out true and false detection to bank note to be measured, bank note to be measured can be placed on detection device first, and with
Bank note to be measured is set to be equipped with the eddy current detection unit that non magnetic safety line one side faces detection device.Optionally, on bank note to be measured
Non magnetic safety line can be hollow out opened window safety line in 100 yuans of latest edition in 2015, but be not intended as to this
The restriction of embodiment.
Afterwards, detection device presses the eddy current detection unit movement on default moving direction control detection device, so that inspection
Measurement equipment can perform eddy current detection by default moving direction to the non magnetic safety line on the bank note to be measured.
Such as shown in Fig. 3, on the RMB for being 100 for a face amount on bank note A to be measured, the institute in the bank note A such as figure to be measured
In the orientation shown, the right side of bank note A to be measured is high line there is the hollow out opened window safety line region B of multiple strips, Mei Gechang

It is low line between the hollow out opened window safety line region B of adjacent strip.Further, detection device is to dotted line on bank note A to be measured
Boxed area C is checked, and the default moving direction of detection device can be the side in the orientation of Fig. 3 displayings from the bottom to top
To or direction from top to bottom.
During detection device presses default moving direction to the bank note to be measured execution such as exemplary eddy current detections of Fig. 3,
Include the non magnetic safety line region in bank note to be measured in the region that detection device needs to detect.Therefore in the mistake for performing the detection
Cheng Zhong, checks the sustainable detection signal for obtaining bank note to be measured of detection device, and detects in signal and include non magnetic safety line
The high low signature of the high line in the region non magnetic safety line corresponding with low line.
It is understood that detection device is detected bank note to be measured based on current vortex, the Lift-off effect of the current vortex
The intensity for characterizing detection device is obtained when bank note distance measuring device to be measured is nearer magnetism or inductance signal is bigger.Cause
This, high line enables detection device to detect and exports a high level signal in non magnetic safety line region, is " 1 ".Conversely,
Low line enables detection device to detect and exports a low level signal in non magnetic safety line region, is " 0 ".Further
, when detecting non magnetic safety line region, detection device obtains non magnetic safety corresponding to the non magnetic safety line region
The high low signature of line is the digital signal being made of 0 and 1, for example, high low signature is：0111011001111, its
In, the quantity of " 1 " corresponds to high line number amount, and the quantity of " 0 " corresponds to low line number amount.
Further, as the progress of detection process, detection device obtain the detection signal of bank note to be measured.According to above-mentioned
Testing principle, it can be that discontinuous high low signature is formed between each other by multistage that detection signal, which obtains detection signal,
I.e. in the signal waveforms that detection signal is presented, it is separated by every between every two sections of high low signatures at a distance
Segment distance is the detection corresponded to non magnetic safety line region.Detection device, can will be every according to default feature extraction algorithm
The target signal filter corresponding to a distance between two sections of high low signatures.Further, based on this feature extraction algorithm, inspection
Measurement equipment then extracts the high low signature of non magnetic safety line corresponding to non magnetic safety line region from detection signal.Obviously
It is understood that when non magnetic safety line region is multiple, the high low signature extracted is as multiple, and each
High low signature is the digital signal being made of 0 and 1.
Step S200：Judge that the high low signature symbolizes high line number amount and low line in the non magnetic safety line
Whether the ratio of quantity meets default ratio.
High low signature in the present embodiment can be multiple, and since detection device is to each high low signature
Processing mode all same, therefore the present embodiment is carried out by taking any one high low signature in multiple high low signatures as an example
Describe in detail.
After high low signature is obtained, since the high low signature is the digital signal to be made of 0 and 1, therefore examine
Measurement equipment carries out feature extraction according to default signal processing rule to the high low signature.Specifically, detection device can obtain
The quantity of high level in high low signature is obtained, that is, obtains in high low signature the quantity of " 1 ", and detection device can obtain
Low level quantity in high low signature, that is, obtain in high low signature the quantity of " 0 ".It is understood that high level
Quantity symbolize high line number amount in the non magnetic safety line, low level quantity symbolizes the low line in non magnetic safety line
Quantity.Such as one high low signature be：0111011001111, then obtain the quantity of high level in the high low signature
For 9, and it is 5 to obtain low level quantity in the high low signature.Further, this illustrates that the high low signature institute is right
In the non magnetic safety line region answered, the quantity of high line is 9, and the quantity of low line is 5.
In the present embodiment, the quantity of high line and low line should be fixed in the non magnetic safety line region of a genuine note,
Further, the ratio of high line and low line is also for certain value in the non magnetic safety line region of a genuine note.Therefore in detection device
A default ratio is pre-set, this presets the ratio of high line and low line in the non magnetic safety line region that ratio is genuine note.
After the quantity of high level in obtaining high low signature and low level quantity, detection device can further basis
The quantity of high level obtains the ratio that high low signature is symbolized compared with low level quantity.Therefore detection device will can compare
Value is compared with default ratio, to judge whether ratio meets the default ratio.As a kind of mode, to avoid error from causing to miss
Detection, detection device can determine whether the difference between ratio and default ratio absolute value whether positioned at a default error range with
It is interior.Wherein, which can be 0%-5%.
Step S300：For it is no when, it is counterfeit money to determine the bank note to be measured, and generate one detection alarm first prompting letter
Breath.
By above-mentioned judgement, when detection device judges that the absolute value of the difference between ratio and default ratio is missed default
When beyond poor scope, for example, the absolute value of difference is 10%, and default error range is 0%-5%.At this time, ratio is with presetting
Difference between ratio is excessive, and detection device can further be judged non-corresponding to the high low signature of the bank note to be measured
Magnetic security line region is mismatched with genuine note, that is, determines that the bank note to be measured is counterfeit money.Detection device according to pre-set control programs then
First prompt message of the detection alarm of generation one, detection device are carried according to first prompt message to perform by display or sound
Show using the teaching process personnel bank note to be measured as counterfeit money.
It should be noted that, although the non magnetic safety line region of bank note to be measured is multiple, but have that any one is non magnetic
Safety line region mismatches when detecting, and can determine that the bank note to be measured is counterfeit money.
Also by above-mentioned judgement, when detection device judges the absolute value of the difference between ratio and default ratio default
When within error range, for example, the absolute value of difference is 1%, and default error range is 0%-5%.At this time, detection device is sentenced
Determine the non magnetic safety line Region Matching corresponding to ratio.But detection device needs to determine whether the ratio is multiple non-
Last in multiple ratios corresponding to magnetic security line region, i.e. detection device judge whether after testing to multiple
Last non magnetic safety line region in non magnetic safety line region.
For it is no when, then illustrate that currently detected non magnetic safety line region is not last, for example, non magnetic peace
All fronts region has 5, and current is to detect the 3rd successively.Therefore detection device can return to and perform step S200, to continue to sentence
It is disconnected.
When to be, then illustrate that currently detected non magnetic safety line region is last, and last region leads to
It is also matching to cross inspection.Last region by check also for matching when, detection device can determine whether out all non magnetic
Safety line region matches, and detection device and then can determine whether out that the bank note to be measured is genuine note.Detection device is according to default control journey
Sequence then generates the successful second prompting letter of a detection, and detection device is performed by display or sound according to second prompt message
Prompting is using the teaching process personnel bank note to be measured as genuine note.
