Abstract
The utility model relates to a bank note, ticket detection area specifically are a compound infrared reflectivity detection device of multichannel. This detection device is equipped with infrared emission light source more than two tunnel, more than two tunnel infrared receiving sensor, is provided with infrared receiving sensor in the reflection direction of every way infrared emission light source. Infrared emission light source and infrared receiving sensor place in pairs, and the infrared emission light source is side by side parallel, and infrared receiving sensor is side by side parallel, form array composite construction, and infrared emission light source and infrared receiving sensor set up respectively in the both sides of the perpendicular of bank note. The utility model discloses can compound simultaneously and detect the infrared external reflection characteristic in a plurality of regions of face value, through carry out information fusion to the infrared reflected signal of multichannel after, can integrated analysis judge the infrared external reflection characteristic of face value. The utility model discloses simple structure, the assembly is nimble, can adjust the position of multichannel detected signal according to the detection demand, reaches the testing goal.
Description
Technical field
The utility model relates to banknote, ticket detection field, is specially a kind of multichannel compound infrared reflectivity pick-up unit.
Background technology
Banknote, ticket are all with infrared signature, these infrared signatures are on specific reflection angle, Infrared major part is by nominal value Surface absorption, reflected signal is very weak, and when banknote surface is stained with adhesive tape or other hyaline membrane, infrared emission light cannot be absorbed by nominal value, so the Infrared of reflection is very strong, feature after reflection just has obvious change, by carrying out comprehensive analysis and judgement to the difference of this infrared external reflection feature, can improve the Detection results of banknote.
Utility model content
The purpose of this utility model is to provide a kind of multichannel compound infrared reflectivity pick-up unit, solves detection banknote surface being stained with to adhesive tape, bonding banknote.
The technical solution of the utility model is:
A kind of multichannel compound infrared reflectivity pick-up unit, this pick-up unit is provided with the above infrared emission light source of two-way, the above infrared receiver sensor of two-way, and the reflection direction of every road infrared emission light source is provided with infrared receiver sensor.
Described multichannel compound infrared reflectivity pick-up unit, infrared emission light source and infrared receiver sensor are placed on the homonymy of banknote, and the intersection point of infrared emission light source center line and infrared receiver center sensor line drops in detected banknote nominal value.
Described multichannel compound infrared reflectivity pick-up unit, the angle of infrared emission light source center line and infrared receiver center sensor line is 20-70 °.
Described multichannel compound infrared reflectivity pick-up unit, infrared emission light source and infrared receiver sensor are placed in pairs, infrared emission light source parallel side-by-side, infrared receiver sensor parallel is arranged side by side, form array composite structure, infrared emission light source and infrared receiver sensor are arranged at the both sides of the vertical plane of banknote respectively.
The beneficial effects of the utility model are:
The utility model can the infrared external reflection feature of complete detection whole nominal value, and by the comparison to infrared external reflection characteristic amplitude, rule, detect the true and false and the quality of banknote, its Detection results is obvious, and structure is simple, and cost is lower.
Accompanying drawing explanation
Fig. 1 is the utility model multichannel compound infrared reflectivity pick-up unit schematic diagram.
Fig. 2 is the vertical view of Fig. 1.
In figure, 1 infrared emission light source; 2 infrared receiver sensors; 3 banknotes.
Embodiment
As Figure 1-Figure 2, the utility model multichannel compound infrared reflectivity pick-up unit, mainly comprise: infrared emission light source 1, infrared remote receiver 2, circuit board etc., infrared emission light source 1 is angled with the nominal value of banknote 3, arrange infrared receiver sensor 2 at the reflection direction of infrared emission light source 1, its concrete structure is as follows:
Infrared emission light source 1 and infrared receiver sensor 2 are arranged at the both sides of the vertical plane of banknote 3 respectively, angle between the center line of infrared emission light source 1 and the center line of infrared receiver sensor 2 is 20-70 °, wherein the center line of infrared emission light source 1 is equal with the angle of banknote vertical plane with infrared receiver sensor 2 with the angle of banknote vertical plane, the Infrared that guarantee infrared emission light source 1 is launched, after the reflection of banknote nominal value, reflexes to infrared remote receiver 2 all completely.
In the utility model, infrared emission light source 1 and infrared receiver sensor 2 must be placed in pairs, can adopt array, obtain infrared external reflection characteristic signal by multichannel infrared receiver sensor 2.Compound is carried out to the signal of multichannel infrared receiver sensor, comprehensively analyzes, the true and false and the quality of banknote can be detected.
