Embodiment
As shown in the figure; The present invention includes frame 1, in frame 1, be provided with subsides coin roller 3, be installed on the support 5 with subsides coin roller 3 relative Magnetic Sensors 4 by motor 2 transmissions; Support 5 is slidingly arranged in and pastes on the guide rail 28 that coin roller 3 parallels, and Magnetic Sensor 4 connects computer processing systems 6.Above-mentioned support 5 can match with screw mandrel 7 and be slidingly arranged on the guide rail 28; Screw mandrel 7 connects slippage motor 8 drive supports 5 and moves; Certainly; Support 5 is not limited to match with screw mandrel 7 and is slidingly arranged on the guide rail 28, and screw mandrel 7 can be replaced by other gear train mutually, as long as support 5 is laterally moved; Roll shaft 9 ends of pasting coin roller 3 are provided with speed probe 10; The end of screw mandrel 7 connects displacement transducer 27; Speed probe 10 all is connected computer processing system 6 with displacement transducer 27; Pasted the displacement of Magnetic Sensor 4 on rotating speed and the support 5 of coin rollers 3 by computer processing system 6 control, thereby reach accurate detection, slippage motor 8 can adopt stepper motor.Support 5 comprises carrier base 11, slide 12 and frame plate 13; Magnetic Sensor 4 is fixed on the frame plate 13; Frame plate 13 is articulated in slide 12 through hinge 14, and frame plate 13 is provided with fan-shaped teeth groove 15, and fan-shaped teeth groove 15 matches with gear 16 on the slide 12 can adjust the angle of Magnetic Sensor 4 on the frame plate 13.Carrier base 11 is slidingly arranged on the guide rail 28; Carrier base 11 is provided with chute 17, and slide 12 is slidably disposed in the chute 17 rotating screw bolt 18 through matching with screw rod 18; Slide 12 promptly moves in chute 17, can adjust on the frame plate 13 big spacing between the Magnetic Sensor 4 and subsides coin roller 3.Both sides are respectively equipped with the initial position limiting slide block 29 and termination position limiting slide block 19 of control support 5 slip locations in the frame 1 below pasting coin roller 3; Initial position limiting slide block 29 is respectively equipped with initial limit sensors 20 and stops limit sensors 21 with stopping on the position limiting slide block 19; Initial limit sensors 20 matches with the baffle plate 22 that is fixed on support 5 lower ends with termination limit sensors 21; Initial position limiting slide block 29 is slidingly arranged on the guide pillar 23 with termination position limiting slide block 19; Initial position limiting slide block 29 with stop position limiting slide block 19 and be threaded with separately adjustment screw mandrel 24, rotate initial working position and termination working position that two adjustment screw mandrels 24 can be regulated Magnetic Sensor 4.On frame 1, also be provided with the initial sensor 25 of information acquisition, the initial sensor 25 of information acquisition be arranged on the catch 26 that pastes on the coin roller 3 and match.Initial limit sensors 20, stop limit sensors 21 and the initial sensor 25 of information acquisition all is connected to computer processing system 6.Before the start, bank note is attached on the coin roller 3, bank note edge and the justified margin that pastes coin roller 3 upper stop pieces 26; After the start, what carry out earlier is the reset operation of Magnetic Sensor 4 positions, and slippage motor 8 rotates; Move to initial limit sensors 20 through screw mandrel 7 control Magnetic Sensors 4, blocked by baffle plate 22 up to initial limit sensors 20, slippage motor 8 shuts down; System gets into readiness, after starting working, pastes coin roller 3 and rotates; When catch 26 was passed by the initial sensor 25 of information acquisition, the initial sensor 25 of information acquisition sent a start signal for computer processing system 6, and capture program starts; Support 5 slides on guide rail 28, and Magnetic Sensor 4 begins carry out the AD sampling with the magnetic signal on the bank note that pastes 3 rotations of coin roller.In the present invention, setting speed probe 10 line numbers is M (M is high more, and precision is high more), and pasting coin roller 3 girths is L, and width of paper money is I, and then bank note is walked out-of-date speed probe 10 and can be provided I/L*M pulse.Once appearance is adopted in speed probe 10 pulses of the every reception of system, and the umber of pulse that metering rotating speed sensor 10 provides is gathered N (N >=I/L*M) inferior altogether.After stopping sampling, computer processing system 6 control slippage motors 8 rotate α degree (α calculates according to pitch, sampling lateral resolution), and rotating the α angle needs in M-N pulse, to rotate to finish, otherwise influences the sampling of next line.When umber of pulse reaches M, counter O reset, sampling restarts.Move to when stopping limit sensors 21 or artificial button and stopping up to baffle plate 22, system quits work, and further handles to host computer transmission AD sampled data through computer processing system 6.Above-described embodiment describes the preferred implementation of the device of magnetic information on a kind of detection plane article of the present invention; Be not that the design and the scope of inventing limited; Under the prerequisite that does not break away from the present invention program; Various external form modification and improvement that those skilled in the art make technical scheme of the present invention all should fall into the protection domain of the device of magnetic information on a kind of detection plane article of the present invention.
