The bottom of described bank note conveyer belt 1 is fixed on horizontal plane, is used at the uniform velocity transmitting bank note to be detected,
During conveyer belt, between bank note and bank note conveyer belt 1, there is not relative motion；Described fixed mount
The bottom of base plate 2 is fixed in same level；Described fixing rack for sensor 3 is several font structures, bank note
Conveyer belt 1 is positioned in several font structures of fixing rack for sensor 3, fixing rack for sensor 3 both sides and fixed mount
Base plate 2 upper surface is threaded；Described fixing rack for sensor 3 top be provided with the first photoelectric sensor 4,
Two photoelectric sensor 5 and the 3rd photoelectric sensors 6；First photoelectric sensor the 4, second photoelectric sensor 5 and
3rd photoelectric sensor 6 distance between any two is identical, and scope is 15-17mm, is 16mm in the present embodiment；
Described first photoelectric sensor the 4, second photoelectric sensor 5 and the 3rd photoelectric sensor 6 are perpendicular to bank note transmission
Band 1, and be connected with control module 7 by wire；Described first photoelectric sensor the 4, second photoelectric sensor
5 is identical apart from the distance of bank note conveyer belt 1 with the 3rd photoelectric sensor 6, and scope is 30-800mm, this reality
Execute in example is 250mm.
Described control module 7 include single-chip microcomputer 71, power supply 72, extend out storage chip 73, time chip 74,
LCDs 75 and button 76；Described single-chip microcomputer 71 respectively with power supply 72, extend out storage chip 73, time
Between chip 74, LCDs 75 and stand-alone keypad 76 connect；Described power supply 72 is 12V DC source,
It is responsible for powering to control module 7；Described single-chip microcomputer 71 is AT89C51 model single-chip microcomputer；Described extend out storage
Chip 73 is AT24C02 chip；Described time chip 74 is DS1302 chip；Single-chip microcomputer 71 is from the time
Chip 74 reads current time, and data are stored in extend out in storage chip 73；Described LCDs
Model be TJC4827T043_011, LCDs 75 can demonstrate current coin quantity and total value etc.
Information, button 76 can be used to adjust display information.
Described first photoelectric sensor the 4, second photoelectric sensor 5 and the 3rd photoelectric sensor 6 are that model is
The diffuse-reflectance formula photoelectric sensor of E18-D80NK.
Operation principle and the workflow of note detection device of the present invention be:
Operation principle: first photoelectric sensor the 4, second photoelectric sensor 5 and the 3rd photoelectric sensor 6 are side by side
It is perpendicular to bank note conveyer belt 1 on highland；Three photoelectric sensors distance between any two is identical, for 16mm,
Ensure this bank note to be measured apart from lower any face amount, no matter how to tilt on bank note conveyer belt 1, all can be complete
Entirely block three photoelectric sensors.First photoelectric sensor the 4, second photoelectric sensor 5 and the 3rd photoelectric sensing
The output signal of device 6 connects P3.2, P3.3, P3.6 interface of single-chip microcomputer 71 respectively.By detection P3.2, P3.3,
Whether the condition adjudgement of P3.6 interface has bank note to be measured to arrive, when there is no bank note through out-of-date, and P3.2, P3.3, P3.6
Interface output " 0 " state；When having bank note through out-of-date, if the long limit of bank note is parallel to the edge of bank note conveyer belt 1,
Then P3.2, P3.3, P3.6 interface exports one state simultaneously；If the long limit of bank note is compared with the limit of bank note conveyer belt 1
Edge has certain angle (tilt of paper money), then P3.2, P3.3, P3.6 interface is sequentially output one state；Due to
Bank note conveyer belt 1 at the uniform velocity transmits bank note, therefore blocks the first photoelectricity by bank note on detection bank note conveyer belt 1
Sensor the 4, second photoelectric sensor 5 and the time of the 3rd photoelectric sensor 6, just can get surveyed bank note
Length, through single-chip microcomputer 71 and the different denominations length ranges pre-set relatively after, just can finally sentence
Break and the denomination of surveyed bank note.The a length of 130mm of such as one yuan note, the maximum detected after inclination away from
From for 132mm, fall in the range of 130mm～132mm if being therefore computed length of paper currency, i.e. it is believed that should
The denomination of bank note is unitary, and remaining denomination detection method is similar to.
If bank note to be measured has defect, for worn coin, its size differs with genuine note, then this worn coin is passing
The light of three sensors, now first photoelectric sensor the 4, second light will not be sheltered from during sending simultaneously
The time of blocking that electric transducer 5 and the 3rd photoelectric sensor 6 detect will be incomplete same, the most just
Can decide whether as worn coin.
Work process: after this device assembles, is sent to bank note to be measured on bank note conveyer belt 1, paper to be measured
Coin at the uniform velocity forwards via bank note conveyer belt 1, will block first photoelectric sensor the 4, second photoelectric transfer afterwards
Sensor 5 and the 3rd photoelectric sensor 6.After bank note is completely by three sensors, detection signal is sent to
In control module 7, analyze through single-chip microcomputer 71 and show that bank note to be measured blocks first photoelectric sensor the 4, second light
Electric transducer 5 and the time of the 3rd photoelectric sensor 6, after calculating, draw the face amount and whether of this bank note
Incompleteness, final LCDs 75 demonstrates the information such as the face amount of this bank note and damaged situation, and button 76 can
To be used for adjusting display information.
The present invention does not addresses part and is applicable to prior art.
