Embodiment
Shown in Fig. 1,2,3,4, Renminbi magnetic ink dynamic testing method of the present invention, it is that a Renminbi magnetic ink detection of dynamic mechanism is set between the currency feeding mechanism of paper money counter and cash-out machine structure; And at least three magnetoresistive magnetic heads 9 are set in this testing agency, utilize this magnetoresistive magnetic head 9 to detect the position of Renminbi magnetic ink, magnetic signal by cpu chip control magnetoresistive magnetic head 9, the micro-signal that magnetoresistive magnetic head 9 is collected amplifies, filtering, correction, comparison, convert magnetic signal to digital signal by the A/D analog to digital converter, this digital signal is handled, calculates, judged, finally differentiate the true and false of Renminbi.
The Renminbi magnetic ink detection of dynamic mechanism that the present invention is provided with is arranged between the currency feeding mechanism and cash-out machine structure of paper money counter; Mainly comprise be located on the paper money counter press-note wheel shaft 10 about two money pressing wheels 1, be located in paper money counter to about on the runner shaft 11 two to runner 3; One end of press-note wheel shaft 10 wears a code-disc 6, and code-disc 6 is provided with a secondary code-disc to managing 7.
At press-note wheel shaft 10 and between, be positioned at two money pressing wheels 1, the inboard of runner 3 is provided with at least two secondary penetration infrared emission counting optocouplers 2 and the infrared count pick up optocouplers 4 of penetration runner shaft 11; Between two secondary penetration infrared counting optocouplers 2,4, be provided with at least three magnetoresistive magnetic heads 9, evenly be located on the described press-note wheel shaft 10 with several magnetic head pinch rollers 8 of magnetoresistive magnetic head 9 corresponding settings.
Be not difficult to find out that from Fig. 2 in the present embodiment, three magnetoresistive magnetic heads 9 are provided with at interval with respect to penetration infrared emission, count pick up optocoupler 2,4.And press-note wheel shaft 10 of the present invention, the center line of the center line of runner shaft 11 and penetration infrared counting optocoupler 2,4, magnetoresistive magnetic head 9 is coexisted in the vertical plane.Like this, can guarantee that penetration infrared counting optocoupler 2,4, magnetoresistive magnetic head 9 can synchronous workings, the situation of unlikely generation omission or flase drop.
Detection speed of the present invention: 1000/minute; Sensing range: 100 yuan of quadruplet Renminbi, 50 yuan.
Penetration infrared counting optocoupler 2,4 be installed in press-note wheel shaft 10 under.It can respond to the signals collecting district when currency has entered testing agency, and when tested currency 5 leaves the signals collecting district.
Code-disc 6 is installed on the same axis of money pressing wheel 1 (being on the press-note wheel shaft 10).How many circles money pressing wheel 1 rotates, and how many circles code-disc 6 also just rotates, and code-disc 6 is rotating, and the grid 6a on the code-disc 6 is also rotating, the grid 6a on the code-disc 6 each pass through code-disc to managing 7.
Code-disc is worked under the control of cpu chip to managing 7, when tested currency 5 during at signals collecting district rectilinear motion, gathering code-disc grid 6a rotates by code-disc managing 7 quantity, can calculate currency from having entered the signals collecting district when leaving the signals collecting district, the quantity that code-disc grid 6a is turned over is exactly vertical width of tested currency 5.
Simultaneously, to leaving the signals collecting district once, penetration infrared counting optocoupler 2,4 can calculate a currency, can be used as the number that shows detected currency 5 from tested currency 5 entering signal acquisition zones.
Because quadruplet Renminbi (genuine note) adopts magnetic ink printing, the unusual nonmagnetic printing ink of currency (counterfeit money) adopts common ink to print and forms.According to these characteristics, when tested currency 5 during in the signals collecting district, magnetoresistive magnetic head 9 detects quadruplet Renminbi magnetic inks, and acquired signal.Tested currency 5 is judged when leaving the signals collecting district at once.
Referring to Fig. 5, detection method of the present invention and step are roughly as follows:
On the smooth money-supplying board that is placed on the paper money counter currency feeding mechanism of tested currency 5, drive money pressing wheel 1 behind the electric motor starting, runner 3 rotated, make tested currency 5 be folded in rubber money pressing wheel 1 and between the runner 3, and with certain speed along the B among Fig. 3 to operation.Utilize the signal of two secondary penetration infrared counting optocouplers 2,4 to send into cpu chip, judge whether tested currency 5 enters in the measured zone.
When cpu chip determines currency when being in the measured zone, cpu chip is according to the feedback signal of this two secondary penetration infrared emission, count pick up optocoupler 2,4, control setting at code-disc 6 of press-note wheel shaft 10 1 ends and a secondary code-disc to managing 7, measure the longitudinal signal of tested currency 5, cpu chip utilizes counter to gather this signal.
When tested currency 5 is in the measured zone, the magnetic signal of cpu chip control magnetoresistive magnetic head 9, and under certain relative velocity, the micro-signal that magnetoresistive magnetic head 9 is collected amplifies, filtering, correction, relatively wait a series of processing, and convert magnetic signal to digital signal by the A/D analog to digital converter, cpu chip utilizes the timer acquired signal again, and then the signal that is collected is stored.
When cpu chip determines tested currency 5 when leaving measured zone, cpu chip is put in order and is calculated the data that collect and makes comparisons with standard signal, to differentiate the true and false of tested currency 5.
If there is unusual currency to enter, promptly tested currency 5 is judged as doubtful coin, and paper money counter then quits work and notifies buzzer warning;
If tested currency 5 is normal currency, then continue to detect, show the number of tested currency 5 simultaneously.
