Abstract
The utility model provides an automatic converter for an optical filter of a paper money discriminator, which is provided with a plurality of sets of filter pieces embedded on a platform between tested paper money and a camera in the paper money discriminator, and the platform and a step motor in a control device have transmission connection. The utility model has the characteristics of obvious paper money discrimination effect, easy image observation and processing, etc.
Description
Technical field
The utility model relates to a kind of optical filter automatic transfer equipment, specifically a kind of paper banknote identifier optical filter automatic transfer equipment.
Background technology
Paper banknote identifier is various informative, be to be used for preventing that counterfeit money from flowing to the effective means of monetary field of circulation, existing paper banknote identifier is not owing to adopt the optical filtering means, can not carry out quantitative spectral analysis to the light wave of the different wave length that bank note reflected, along with improving constantly of counterfeit money manufacturing technology, existing paper banknote identifier can not adapt to the needs of monetary field of circulation far away.
The utility model content
The purpose of this utility model is to provide a kind of paper banknote identifier optical filter automatic transfer equipment, and it has the different optical filters that can change automatically.
For achieving the above object, the technical solution adopted in the utility model is:
Optical filter of the present utility model is many groups, is embedded in the paper banknote identifier on the platform between the camera and tested bank note, and the stepper motor in this platform and the control device is in transmission connection.
Described control device has a central processing unit, and its communication pin is connected to primary processor by communication interface, and the digital quantity output terminal of central processing unit is connected to the Stepping Motor Control end by switch; Below cam lens and platform and the corresponding position of optical filter be provided with position transducer, its signal wire is connected to the digital quantity input end of central processing unit; The quantity of described position transducer is identical with the quantity of optical filter, can be optoelectronic switch, microswitch and magnetic switch; Described optical filter is arranged on the platform with form of straight lines, and this platform is in transmission connection by the output shaft of gear, belt or chain and stepper motor; Described optical filter also can be located on the circumference on the platform, and the center of circle of this circumference can directly be fixedly installed on the output shaft of stepper motor, also can be in transmission connection by the output shaft of gear, belt or chain and stepper motor.
The utlity model has following advantage:
1. be installed in the paper banknote identifier owing to the utility model, adopt the different optical filter of optical filtering spectrum, by the fluorescent material on infrared light or the ultraviolet excitation bank note, produce the different fluorescence of spectrum, under the effect of different optical filters, the light that makes required wavelength is by optical filter, and the fluorescence that genuine note and counterfeit money are reflected has obvious difference, is easy to observe.Identification result to bank note is remarkable.

Embodiment
As shown in Figure 1, 2, (present embodiment adopts 6 groups to the utlity model has many group optical filters 1, every group of optical filter can filter spectrum and not share the same light), be embedded in the paper banknote identifier on the platform 2 between the camera CCD and tested bank note 3 with form of straight lines, optical filter 1 is preferably equidistant arrangement, and this platform 2 is in transmission connection by the stepper motor in gear, belt or chain and the control device.
As shown in Figure 5, described control device has a central processing unit IC1, its communication connects P0.0～0.3 and carries out communication by serial interface IC2 (present embodiment adopt MAX232 serial ports) with primary processor and be connected, the digital quantity output terminal DJ3AZ of central processing unit IC1, DJ3AF, DJ3BZ, DJ3BF is connected to the Stepping Motor Control end by switch, stepper motor is 2 phases in the present embodiment, switch adopts 4 triode switches that this stepper motor is carried out stepping control, position transducer (present embodiment employing optoelectronic switch) by relative each optical filter 1 setting, carry out location to optical filter 1, make optical filter 1 when stepper motor stops, its center is positioned at the below of camera just, and the signal wire of position transducer is connected to the digital quantity input end of central processing unit IC1 by interface JTWZ1.
The course of work of the present utility model is as follows: receive the control command that primary processor transmits by central processing unit IC1 by the MAX232 serial line interface, the control step motor drives platform 2 translations by gearing (present embodiment employing belt), by stopping of position transducer control step motor, platform 2 moves each time, switch one time optical filter 1, because under the exciting of light beam, the spectrum difference of bank note reflected fluorescent light, by different optical filter 1 light of required wavelength is passed through, picked up by camera, the fluorescence that genuine note and counterfeit money are reflected has obvious difference, and carries out quantitative spectral analysis.
Shown in Fig. 3,4, be with the difference of embodiment 1: optical filter 1 is located on the circumference on the platform 2, be preferably on this circumference and evenly be provided with, platform 2 directly is fixedly installed on the output shaft of stepper motor at the home position of this circle, also can be in transmission connection by the output shaft of gear, belt or chain and stepper motor.The every action of progressive motor once just drives position of platform rotation, has realized the switching to different optical filters 1.
