Abstract

The utility model discloses a coin sorting and counting device capable of sorting and counting mixed coins, which comprises an upper module, a lower module and a guide rail, wherein the guide rail is arranged above the lower module; an infrared light source is arranged on the upper module; a CCD module and a microprocessor which is connected with the CCD module are arranged on the lower module; and when the coins pass through the guide rail, light rays sent by the infrared light source can be shielded, so the intensity of light received by the surface of the CCD module is changed, the output voltage of the CCD module is continuously changed, and the microprocessor calculates the maximum voltage change value which corresponds to the coin diameter. The utility model can automatically judge the face value of the coins, can sort and count the coils, and has the advantages of high efficiency and high practicability. In addition, in the whole detecting process, the coins are not in contact with photoconducting devices; and simultaneously, the utility model has a simple structure, and can be directly used for occasions for detecting the existing currency.

Description

Can be to the coin checking device of mixing coins differential count

Technical field

The utility model relates to a kind of currency checking device, be specifically related to a kind of can be to the coin checking device of mixing coins differential count.

Background technology

General employing is that photoelectric sensor is counted processing in the existing coin checking device, be coin in the middle of sensor emission pipe and receiving tube by the time, output low level is not when having coin to pass through, the output high level, single-chip microcomputer is judged quantity by coin by the variation of high-low level.Because this coin checking device can only be judged the quantity by coin, and the face amount of coin can't be judged,, then the judgement of every kind of number of coins can not be carried out mixing coins so can only carry out the counting of coin of the same race.

Summary of the invention

The utility model purpose is: at the deficiency of the existing coin checking device of mentioning in the background technology and provide a kind of can be to the coin checking device of mixing coins differential count.

The technical solution of the utility model is: a kind of can be to the coin checking device of mixing coins differential count, it comprises upper module, lower module and is installed in the guide rail of lower module top; Described upper module is provided with infrared light supply, the microprocessor that described lower module is provided with the CCD module and is electrically connected with the CCD module; Described coin is when guide rail passes through, the light that infrared light supply can be sent blocks, and the light intensity that makes CCD module surface receive changes, thereby the voltage of CCD module output is constantly changed, the maximal value that described microprocessor calculating voltage changes, this value is corresponding with coin diameter.

Infrared light supply described in the utility model further provides the directional light perpendicular to the CCD module.

The infrared source circuit plate specifically is installed on the upper module described in the utility model, and described infrared light supply is electrically connected with described infrared source circuit plate.

Lower module described in the utility model further vertically is installed on the upper module below.

The utility model also comprises orders about the coin transport means of coin by guide rail.

And the preferred travelling belt of described coin transport means.

Module of CCD described in the utility model and microprocessor are prior art, described CCD module can change the voltage change signal that is converted into correspondence with the light intensity that is radiated at its surface, and described microprocessor comprises sequential control circuit and analog to digital conversion circuit, is responsible for the voltage change signal of CCD module output is transformed into digital signal corresponding.No longer describe in detail with the concrete control technology that is connected between microprocessor for the CCD module in the utility model.

The concrete principle of work of the utility model is as follows: described infrared light supply provides the directional light perpendicular to the CCD module, when coin can block light when CCD module surface is passed through, and at CCD module surface shading, along with moving of coin, the shaded area respective change, the light intensity that makes CCD module surface experience constantly changes.The light intensity that the CCD module will shine its surface changes and to be converted into the correspondent voltage variable signal and to export to microprocessor, by microprocessor these voltage change signals are handled again and be transformed into value corresponding, and obtain maximal value in these numerical value, this maximal value is exactly the relative value of corresponding coin diameter, the coin of different denominations is owing to the diameter difference, so corresponding relative value is also different.Along with the continual conveying coin of conveyer by guide rail, microprocessor constantly obtains the relative value of corresponding different denominations coin diameter, and computing simultaneously draws the same peaked quantity that occurs, this quantity also is the quantity of par value coin of the same race.The utility model is differentiated coin value by above-mentioned detection means just, and these coins is classified check.

The utility model advantage is:

The utility model can be differentiated the face amount of mixing coins and automatically to they differential counts, and the efficient height is practical; And in whole testing process, coin does not contact with photoelectric device; The utility model is simple in structure simultaneously, can directly apply to existing currency and detect occasion.
