Financial self-service device, banknote recognition module thereof and recognition method therefor

摘要

A recognition module comprises a detection unit for real-time detection and control of a banknote moving state, wherein at least one group of the through-beam sensors comprises a first sensor and two second sensors, the first sensor whereof is arranged on a midline of a banknote transmission channel, and the two second sensors are arranged at the upstream position of the banknote moving direction relative to the first sensor and are symmetrically distributed on the two sides of the midline of the banknote transmission channel. The condition for judging whether a start signal of an image data acquisition unit is effective is whether a banknote-triggered insertion event is detected by the first sensor; and the condition for judging whether an end signal of the acquisition unit is effective is whether a banknote-exit completion event is detected by three through-beam sensors.

主权项

1. A banknote identification module comprising:
a monitoring unit, adapted to monitor in real time a moving state of a banknote in a conveying passage; an acquisition unit, adapted to start or stop acquiring image information of the banknote according to a starting or stopping signal provided by the monitoring unit; a counting unit, adapted to count the number of banknotes according to the times by which the acquisition unit acquires image information; an identification unit, adapted to identify the banknote according to the image data acquired by the acquisition unit and output a final identification result to a main control center for synthetic decision on a destination of the banknote; wherein the monitoring unit comprises at least one set of opposite-type sensors, and the set of opposite-type sensors comprises one first sensor and two second sensors; the first sensor is disposed at a central line of the conveying passage, and the two second sensors are disposed at an upstream location from the first sensor in a moving direction of the banknote and arranged symmetrically on two sides of the central line of the conveying passage, wherein the acquisition unit comprises a image sensor disposed at a downstream location from the set of opposite-type sensors in the moving direction of the banknote and separated from the set of opposite-type sensors at a distance; the distance between the second sensor and the image sensor is greater than the distance between the first sensor and the image sensor.
