Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Such as figure 1 As shown, the Hall-type detection device for banknote thickness of the present invention includes a plurality, such as 10 magnets that follow the follower roller assembly one by one, and the follower rollers are arranged at intervals along a straight line, one by one Correspondingly to the magnet, the Hall sensor arranged above it is fixed, that is, the Hall sensor does not move with the follower stick, and the Hall module composed of the Hall sensor and the magnet is used to transfer the magnetic flux caused by the thickness of the banknote The change is converted into a voltage signal; the signal amplification circuit is used to amplify the output voltage si...

Abstract

The present invention discloses a Hall-type detection device used for detecting thickness of paper money. The device comprises magnets moving along with a servo roller assembly, and Hall sensors; a signal amplification circuit used for amplifying a voltage signal output by the Hall sensors to be within a detection range; a channel selection circuit used for carrying out multi-channel switching on the signal processed by the signal amplification circuit and connected to a signal collection circuit; and a controller for receiving the digital signal output by the signal collection circuit, outputting the digital signal to an external circuit through an external connector, and generating a switch control signal of the channel selection circuit. The Hall-type detection device provided by the present invention is stable in function, fast in response speed, and capable of precisely detecting the thickness of paper money. Changes of output values of the Hall sensors are caused by the servo rollers, thus to achieve the thickness measuring aim, information about whether the paper money is stuck can be obtained, and the number of the paper money can also be obtained.

Description

technical field [0001] The invention relates to the technical field of financial automatic service terminals, in particular to a Hall-type detection device for banknote thickness. Background technique [0002] In order to ensure accurate counting of processed banknotes in cash processing equipment (banknote counting machines, recycling machines, sorting machines, etc.), a thickness detection device is equipped. The function of the thickness detection device in cash processing equipment is to detect the thickness of sheet media. That is, the thickness of banknotes. Obtaining the thickness of banknotes can not only be used to judge whether it conforms to the characteristics of real banknotes, but also can ensure the accuracy of counting when banknotes are separated and transported, and provide guarantee for quantitative and qualitative banknotes provided by cash processing settings. The current cash processing equipment generally uses ultrasonic sensors to detect the thickness...
