The principle of work of cash inspecting machine of the present utility model below underdraws:
As shown in Figure 1, transformer 4 provides the AC power of 9V to 12V for power circuit 5, and power circuit 5 is used to drive purple light fluorescent tube 303, and purple light fluorescent tube 303 provides light source for spectrum dash receiver 306.Power circuit 5 is simultaneously also for main control board 7 provides direct supply, and main control board 7 supplies other each sensor module with treated power supply again.Infrared emission assembly 310 emission infrared rays give the back infrared receiving unit 304, and the infrared receiving unit 304 in back send main control board 7 with the infrared transmission signal that receives again.Infrared and ultraviolet emitting module 309 emission infrared rays are given preceding infrared receiving unit 0307, preceding infrared receiving unit 3 07 send main control board 7 with the infrared transmission signal that receives again, infrared and ultraviolet emitting module 3 09 is also launched purple light and is given purple light receiving unit 305, and purple light receiving unit 305 send main control board 7 with the purple light signal that receives again.Infrared external reflection assembly 308 send main control board 7 with the infrared external reflection signal that receives.Spectrum receiving unit 306 send main control board 7 with the spectral signal that receives; The signal that each sensor module on 7 pairs of darkroom assemblies 3 of master control board sends is handled, and the result is delivered to pilot lamp panel 6 shows.Pilot lamp panel 6 is finished power supply indication, the indication of true and false coin and is doubted the function of coin indication.
Further specify the course of work of the utility model cash inspecting machine below in conjunction with accompanying drawing.
The paper money mode of advancing of cash inspecting machine regulation of the present utility model is that " People's Bank of China " printed words advance and detect the darkroom on earth towards right (having only a quadruplet Renminbi left side in 10 the Yuan Dynasty) straight inlet slot of paper note right side of being close to banknote to be checked front (the bust one side is arranged) up.Since the infrared transmitting tube 3101 and 3103 on the infrared emission assembly 310 respectively with the infrared receiving unit 304 in back on back infrared receiving tube 3041 and the position of the 3043 infrared correlation pipes of forming of two couples by the back and the right in detection darkroom, whether therefore can be used to detect banknote puts in place fully, and the signal that puts in place fully that will receive by the infrared receiving unit 304 in back send main control board 7, amplify the processing of A/D change-over circuit again through the signal of main control board 7, the signal after will handling at last send CPU to judge.Simultaneously, when 100 yuan of old editions or 50 yuan of banknotes put in place fully, the a pair of infrared correlation pipe that back infrared receiving tube 3042 on the infrared receiving unit 304 of infrared transmitting tube 3102 on the infrared emission assembly 310 and back is formed just in time faces toward the watermark position of banknote, the infrared transmission signal at this position that infrared receiving unit 304 just will receive like this, papery thickness signal and back positioning signal are sent main control board 7, amplify the processing of A/D change-over circuit again through the signal of main control board 7, the signal after will handling at last send CPU to judge.
As Fig. 2 and shown in Figure 4, preceding infrared transmitting tube 3091 on the infrared and ultraviolet emitting module 309 and preceding infrared receiving tube 3071 on the preceding infrared dash receiver 307 infrared correlation pipe that partners, can detect the infrared transmission feature on 100 yuan of old editions and base, 50 yuan of left sides, whether the width that also detects banknote simultaneously is overproof, the infrared transmission signal and the left width signal at this position that infrared dash receiver 307 just will receive are like this sent main control board 7, amplify the processing of A/D change-over circuit again through the signal of main control board 7, the signal after will handling at last send CPU to judge.Photoresistance 3051 on purple LED power valve 3092 on the infrared and ultraviolet emitting module 309 and the purple light receiving unit 305 and red color filter 3052 purple light that partners transmits and receives assembly, can detect the purple light shine-through feature of new old edition Renminbi and the fluorescence secret mark feature of new edition Renminbi, the purple light at purple light receiving unit 305 this position that just will the receive fluorescence secret mark signal that penetrates signal and new edition Renminbi send main control board 7 like this, amplifying the processing of A/D change-over circuit again through the signal of main control board 7, also is at last to send CPU to judge the signal after handling.
The infrared external reflection pipe 3081 of described infrared external reflection pipe assembly 308 is that infrared emission receives the one pipe, can detect the human head picture position infrared external reflection feature of 10 yuan of old editions, also be used for prelocalization simultaneously, the infrared external reflection signal and the prelocalization signal at infrared external reflection pipe assembly 308 this position that just will receive send main control board 7 like this, amplify the processing of A/D change-over circuit again through signal, the signal after will handling at last send CPU to judge.
As shown in Figures 2 and 3, main control board more than 7 pairs each the sensor board signal on the darkroom assembly 3 handle, and the result delivered to pilot lamp panel 6 show.Pilot lamp panel 6 is finished power supply indication, genuine note indication and is doubted the function of coin indication.Be expressed as genuine note one if " genuine note " pilot lamp is bright and ring " toot ", if " doubting coin ", then pilot lamp glimmers and sends the chimes of doom that does not stop and is expressed as doubtful coin.
This shows,, therefore can increase substantially the false distinguishing reliability because cash inspecting machine of the present utility model has been set up purple LED power valve and infrared external reflection sensor, and has considered new old edition banknote simultaneously in the position of arranging sensor groups.
Be noted that and make some changes to the structure of cash inspecting machine of the present utility model.For example, change into banknote to be checked front (the bust one side is arranged) down if advance the paper money direction, " People's Bank of China " printed words are the straight inlet slot of paper note left side of being close to towards a left side (having only the quadruplet Renminbi right side in 10 the Yuan Dynasty), advances and detects the darkroom on earth.Then the cover plate up and down of the darkroom assembly 3 among Fig. 4 should exchange, but its basic configuration is still constant, and the position of the relative genuine notes of each sensor is also constant.Each infrared sensor can adopt infrared emission to receive split-type pipe, or part adopts infrared emission to receive the one pipe.The position of purple light fluorescent tube also can be placed on the darkroom assembly below.In addition, main control board 7 can also change the integrated circuit AT89C2051 of signal controlling part with other universal single-chip microcomputer IC into.These simple conversion all are protection domains of the present utility model.
