Description
Technical field
The utility model relates in paper money transaction or the sorting process width of paper money and spacing detects and the device of number statistics.
Background technology
The all-in-one of depositing and withdrawing carries out paper money transaction or cleaning-sorting machine when carrying out paper currency sorting, need carry out residue detection and counting statistics to the bank note in the passage.In the prior art, judge the residual of bank note and statistics number, or be blocked and the rising edge and the negative edge that do not block the high-low level that produces carry out counting statistics through infrared sensor through detecting whether being blocked of infrared sensor.Its shortcoming is to judge that bank note is overlapping, card paper money phenomenon, even leaks meter, causes the shortage of money phenomenon.
Summary of the invention
The purpose of the utility model provides a kind of paper money transaction or sorting process of being used for to width of paper money with spacing detects and the device of number statistics; Through the width of detection bank note and the umber of pulse of spacing; Realization has overcome the deficiency that prior art exists preferably to the precise statistics of bank note number.
The device of realizing the utility model is: comprise some infrared sensors, MUX, analog to digital conversion circuit, timer and data processing and logic control chip, wherein: some infrared sensors connect data processing and logic control chip through MUX and analog to digital conversion circuit; Data processing and logic control chip connect analog to digital conversion circuit through timer; Data processing and logic control chip connect MUX.
The beneficial effect that the utlity model has: this device all-in-one that is applied to deposit and withdraw carries out paper money transaction or cleaning-sorting machine and width of paper money and spacing is detected when carrying out paper currency sorting; And precise statistics bank note number; Can in time find away to occur card paper money in the paper money process and take counter-measure; Can write down the overlapping and separation case of bank note, avoid financial dispute.

Fig. 2 is the bank note note distribution synoptic diagram of the utility model.
Fig. 3-4 is the data sampling synoptic diagram of the utility model.
Fig. 5 is the process flow diagram of the utility model.
Among the figure: 11 data processing and logic control chip, 12 timers, 13 analog to digital conversion circuits, 14 MUXs.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
This device is made up of some infrared sensors (1-n), MUX 14, analog to digital conversion circuit 13, timer 12, data processing and logic control chip 11.Some infrared sensors connect data processing and logic control chip 11 through MUX 14 and analog to digital conversion circuit 13; Data processing and logic control chip 11 also connect analog to digital conversion circuit 13 through timer 12; Data processing and logic control chip 11 also connect MUX 14.
The course of work:
The normal detection:
1. after bank note is separated by bank note separating wheel, get into the transmission channel operation, as shown in Figure 1.
2. detecting unit carries out data sampling according to fixing clock frequency to infrared sensor in the passage; And write down infrared sensor signal high level number of times and the low level number of times that samples respectively, as using " bank note umber of pulse " and " gap pulsed " expression among Fig. 2 respectively.
3. calculate width of paper money and spacing through umber of pulse, when walking paper money speed one regularly, every corresponding umber of pulse of paper money is consistent; One timing of note distribution speed, spacing also is certain between the bank note, pairing umber of pulse is certain; Thereby calculate the width and the spacing of bank note.
4. the umber of pulse of statistics is then thought a complete banknote in the scope of preset width of paper money umber of pulse, carries out the number statistics.
Overlapping bank note and malsegregation detect:
Because friction force is bigger between new note, bank note overlapping phenomenon or malsegregation cause the bank note excesssive gap when note distribution occurring, and be as shown in Figure 3.Compare through record high-low level number of times and normal value, can effectively identify by note distribution bad error and card paper money fault.
Above example, employing be sensor when detecting bank note reaction is high level that reaction is low level when detector gap; But this patent is not limited to this, and sensor reaction when detecting bank note is low level, and reaction also is suitable for for high level when detector gap; Method is the same, does not repeat for example.
The principle of work explanation:
When a. the bank note medium was through sensor, according to the situation of blocking of medium and the penetrating light intensity of medium, sensor sensing went out the simulating signal that voltage magnitude does not wait, like Fig. 3, shown in Figure 4;
B. detecting unit carries out data sampling according to fixing clock frequency to infrared sensor in the transmission channel; And the infrared sensor signal high level number of times and the low level number of times that sample of record respectively; Wherein high level number of times and low level number of times are represented bank note umber of pulse and droped beat strokes per minute respectively, like Fig. 3, shown in Figure 4;
C. calculate width of paper money and spacing through umber of pulse, when one timing of bank note medium transmission speed, every corresponding umber of pulse of bank note is consistent; One timing of bank note velocity of separation, spacing also is certain between the bank note, pairing umber of pulse is certain; Thereby calculate the width and the spacing of bank note;
D. the umber of pulse of statistics is then thought a complete banknote in the scope of preset width of paper money umber of pulse, carries out the number statistics.
E. for can active zone the high-low level of sub sensor signal; We adopt " differential technique " to judge; The magnitude of voltage that samples when promptly utilizing the magnitude of voltage that samples when having bank note to block sensor and not having bank note to block sensor compares, if the difference of the two is greater than the threshold values of setting, then magnitude of voltage is high is judged to be high level; Magnitude of voltage is low is judged to be low level; If the two difference then is judged to be sensor failure less than setting threshold values, need carry out adjustment of sensor drive electric current or emat sensor more.
