Abstract
The utility model discloses a magnetic detection array note counterfeit distinguishing device which comprises magnetic heads mounted in a money counter/detector, wherein five magnetic heads are arranged, namely a left magnetic head, a left middle magnetic head, a right magnetic head, a right middle magnetic head and a right magnetic head corresponding to the magnetic signals at the left part, left middle part, middle part, right middle part and right part of the breadth of the detected note; and each magnetic head is connected with a magnetic signal amplifying circuit to form a multi-magnetic head detection array mechanism. According to the utility model, multiple magnetic heads can perform magnetic signal comprehensive distribution induction analysis on the whole breadth of the note, realizes sensitivity and reliability in distinguishing the magnetic features of the true and counterfeit money, has high accuracy and can be used for greatly improving the counterfeit distinguishing performance of the money counter/detector while the detection parts are comprehensive and reasonable.
Description
Technical field: the utility model relates to the magnetic detection false-identifying device that uses in a kind of currency counting and detecting machine tool.
Background technology: present bank note generally all is provided with safety line, and safety line is a kind of magnetic material, and the magnetic characteristic has certain rule.Also have many positions to adopt special magnetic ink printing on the bank note, equally also have certain magnetic characteristic rule.Many currency counting and detecting machine tools are provided with magnetic detection device, but mostly are to survey the local magnetic signal of safety line or magnetic ink, can not carry out the magnetic signal induction analysis that comprehensively distributes to the whole breadth of bank note, and the false distinguishing accuracy of magnetic characteristic has much room for improvement.
Summary of the invention: to the deficiency of prior art, the utility model provides a kind of magnetic detection array bank note false-identifying device that can carry out the magnetic signal integrated sensor cable to the whole breadth of bank note.
The utility model comprises the magnetic head that is installed in the currency counting and detecting machine tool; Said magnetic head has five; Be respectively magnetic head and right magnetic head in magnetic head in left magnetic head, the left side, middle magnetic head, the right side; Corresponding left part, middle part, a left side, middle part, right middle and the right part position magnetic signal of surveying the bank note breadth, and each magnetic head all connects the magnetic signal amplification treatment circuit, formation multihead detection arrays mechanism.
A plurality of magnetic heads of the utility model can carry out the magnetic signal induction that comprehensively distributes to the whole breadth of bank note to be analyzed, and surveys the position comprehensive and reasonable, magnetic characteristic true, counterfeit money is distinguished responsive reliable, and degree of accuracy is high, can improve the false distinguishing performance of currency counting and detecting machine tool greatly.
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Description of drawings: Fig. 1 is the structural principle synoptic diagram of embodiment.
Embodiment:Embodiment: as shown in the figure; The magnetic head that is installed in the currency counting and detecting machine tool has five; Be respectively magnetic head 4 and right magnetic head 5 in magnetic head 2, middle magnetic head 3, the right side in left magnetic head 1, the left side; Corresponding left part, middle part, a left side, middle part, right middle and the right part position magnetic signal of surveying bank note 7 breadths, and each magnetic head all connects magnetic signal amplification treatment circuit 6, formation multihead detection arrays mechanism.The top of the position of magnetic head 4 deflection bank note 7 breadths in the magnetic head 2 and the right side in the left side of present embodiment, 3 of middle magnetic heads are rectangular big magnetic head, detecting location is more reasonable like this, and is more comprehensive to the induction of magnetic signal.
During work, each magnetic head outputs to the magnetic signal that bank note 7 each position induction produce in the magnetic signal amplification treatment circuit 6, is processed into corresponding magnetic characteristic synthetic distribution signal then, offers the currency counting and detecting machine tool and compares false distinguishing, and it is reliable to distinguish sensitivity, and degree of accuracy is high.
