Description
Technical field
The utility model relates to a kind of Renminbi incompleteness degree counter.
Background technology
Incompleteness, stained Renminbi should gratuitously be exchanged for the public by the financial institution (hereinafter to be referred as financial institution) of People's Bank of China's incomplete stained Renminbi exchange way regulation Renminbi the deposit or the withdrawal.Bank adopts naked eyes and the range estimation of complete bank note mostly for the calculating of the incomplete degree of worn coin, and this kind method shortcoming is that the result is inaccurate, and error is bigger, and staff's experience is had relatively high expectations.The staff who also has asks area of a polygon with the size on a plurality of limits of ruler measurement worn coin.This kind measured computing method, and accuracy is higher, but complex operation, calculation of complex, particularly some are through burning, and irregular bank note weares and teares.The accuracy of above computing method ubiquity is not high, complex operation, calculation of complex, shortcoming such as efficient is low.
The utility model content
At above-mentioned deficiency, the utility model type provides a kind of Renminbi incompleteness degree counter.
The utility model is achieved through the following technical solutions: Renminbi incompleteness degree counter, and mainly by a plurality of infrared transmitting tubes, a plurality of infrared receiving tubes, infrared emission drive circuit, infrared received signal conditioning circuit, single-chip microcomputer, the input button, liquid crystal is formed; Wherein single-chip microcomputer connects input by, liquid crystal and infrared emission drive circuit and infrared received signal conditioning circuit; A plurality of infrared transmitting tubes form arranged and form the infrared light emission element; A plurality of infrared receiving tubes form the infrared light receiving matrix and form infrared receiving-member; Infrared emission drive circuit links to each other with a plurality of infrared transmitting tubes, and a plurality of infrared receiving tubes link to each other with infrared received signal conditioning circuit.
Described infrared emission drive circuit produces continuous high-frequency drive pulse current and drives the continuous infrared light of infrared transmitting tube generation, and infrared received signal conditioning circuit amplifies conditioning with the reception information of infrared receiving tube and flows to single-chip microcomputer.
Used measuring sensor is infrared light power valve and infrared light receiving tube.The infraluminescence driving circuit produces continuous high-frequency drive pulse current and drives the continuous infrared light of infraluminescence pipe generation, and infrared receiving conditioning circuit amplifies conditioning with the reception information of infrared receiving tube and flows to single-chip microcomputer.Single-chip microcomputer obtains the revolution mark of tested worn coin by reading the infrared receiving tube signal, draw the number of the power valve that is not blocked.Button input need to select Currency Type and year of issue generation of the worn coin measured, and the counter storage inside has the area of corresponding complete bank note, compares the incomplete degree that obtains tested worn coin by the area of the worn coin measured and the area of complete bank note.After the incomplete degree of worn coin was finished by correct measurement, measurement result can be passed through liquid crystal display displays, and display parameter comprise, the real surplus area of tested bank note, incomplete degree and the amount of money that should change.
During Renminbi incompleteness degree calculator application described in the utility model, the Renminbi of incompleteness is placed between a plurality of infrared light power valves and the infrared light receiving tube, measures then and calculate.Incomplete Renminbi reserve part shelters from the light that infrared transmitting tube sends, and the infrared light that the infrared transmitting tube of broken partial section sends can be received by infrared receiving tube smoothly.By reading the infrared receiving tube signal, draw the number of the power valve that is blocked, obtain the area of the residual fraction of worn coin.This calculator structure is simple, and the accuracy height is easy and simple to handle.
Description of drawings
Fig. 1 is a structural principle synoptic diagram of the present utility model.
Wherein, 1, infrared receiving tube 2, infrared received signal conditioning circuit 3, liquid crystal 4, single-chip microcomputer 5, input button 6, infrared emission drive circuit 7, infrared transmitting tube.
Embodiment
Among Fig. 1, a plurality of infrared transmitting tubes 7 are arranged an infrared emission light matrix in the circuit board, and a plurality of infrared receiving tubes 1 form and launch the receiving matrix of light correspondence.Infrared emission drive circuit 6 receives the instruction of single-chip microcomputer 4, drives infrared transmitting tube 7 and launches the matrix infrared light.Infrared received signal conditioning circuit 2 is converted to electric signal to the light signal that infrared receiving tube 1 receives, and conditioned signal is sent to single-chip microcomputer 4.A plurality of infrared transmitting tubes 7 are installed in the housing top of a rectangle, and a plurality of infrared receiving tubes 1 are installed in lower part of frame, and housing leaves the space between the upper and lower, deposits tested worn coin.By input button 5, import measured emission of banknotes age and face amount to single-chip microcomputer 4.Single-chip microcomputer 4 obtains the area of complete bank note by program by the model of the bank note of selection.This Renminbi incompleteness degree counter design is light and handy, easy and simple to handle.
When use calculating the incomplete degree counter of Renminbi, the complete laid out flat of measured Renminbi between infrared transmitting tube 7 matrixes and infrared receiving tube 1 matrix.Startup on pushing button input button 5 is selected value of money and year of issue generation of tested worn coin.Single-chip microcomputer 4 control infrared emission drive circuits 6 produce emission voltage and are applied on infrared transmitting tube 7 matrixes.Infrared transmitting tube 7 sends the matrix infrared light under the driving of infrared emission drive circuit 6, points to infrared receiving tube 1.Infrared transmitting tube 7 matrixes are launched infrared light simultaneously, and these infrared lights have part to be radiated on the worn coin to be blocked by worn coin and can't shine infrared receiving tube, part infrared light direct irradiation with its corresponding infrared receiving tube 1 on.On whole infrared receiving tube 1 matrix, by infrared light-struck infrared receiving tube conducting, produce Continuity signal, the then not conducting of part infrared receiving tube of being blocked by worn coin.Infrared received signal conditioning circuit 2 the respective signal of infrared receiving tube 1, by computing amplification and Filtering Processing, outputs on the single-chip microcomputer 4.Single-chip microcomputer 4 calculates the number of the photoelectric tube that is blocked, and according to each infrared receiving tube physical size, obtains the area of all photoelectric tubes that are blocked, thereby obtains the real area of measured worn coin.
Single-chip microcomputer 4 stores People's Bank of China, and all have been issued and the paper money in circulation full-size.Before the use, select the model of the pairing complete bank note of tested worn coin with input button 5.Single-chip microcomputer 4 just reads the details of the complete bank note that is stored in self automatically, and these information comprise the complete area of complete bank note, value of money lamp.Measure and finish, single-chip microcomputer 4 compares the residual area of the worn coin of measuring and the area of complete bank note, obtains the incomplete degree of tested worn coin.Multiply by the value of money of complete bank note by formula with the incomplete degree of tested worn coin, obtain the amount of money that tested worn coin should be exchanged.Calculating finishes, and single-chip microcomputer 4 drives liquid crystal 3 and shows measuring result of calculation, and displaying contents comprises, the area of the corresponding complete bank note of tested worn coin, and the amount of money that the area value of money of value of money and tested worn coin should have been exchanged is for staff's reference.
