Description of drawings

Fig. 1 is the structural representation of a kind of multifunctional image plate of the utility model.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as restriction of the present utility model.

Be illustrated in figure 1 as a kind of multifunctional image plate, be used for the identification note true and false, comprise the first controller and second controller, the first controller is fpga chip, and second controller is dsp chip; The first controller is connected with the UPP interface by the EMIF interface with second controller, is connected with analog to digital conversion parts (AD chip) and contactless sensing element on the first controller, and the analog to digital conversion parts are connected with sensing element;

Sensing element is used for gathering the information of bank note, and information is sent to the analog to digital conversion parts, and the analog to digital conversion parts receive information and conversion, then information are sent to the first controller.

Be connected with a constant current source chip at contactless sensing element, this constant current source chip also connects fpga chip, is used for offering the required electric energy of this multifunctional image plate normal operation.
