Description

The minimum card setting device that carries of card vending machine

Technical field

The utility model relates to a kind of relatively control device, the minimum card setting device that carries of particularly a kind of card vending machine.

Background technology

Smart-card dispenser of the prior art comprises card case, card-issuing device and coin identifying device, the card case connects card-issuing device and coin identifying device respectively, after people import a bank note, after coin identifying device receives this bank note and confirms, the driver card case will be blocked cartoon in the case cross card-issuing device card is sent.Its weak point is: in actual operation process, general size and selected Card Type card release according to filling in Renminbi face amount, but when the card in a certain class card case only is left one, because of also having card in the card case, so corresponding prompt is shown as normally, and that the client fills in face amount is double in the Renminbi of this card calorific power, want to buy two such cards, at this moment, the card number in the card case is undesirable, will cause card vending machine to break down easily.For example, the card of only remaining 50 yuan of face amounts when the client fills in 50 yuan, can normally be bought this card in the card case, and after this card vending machine also will be pointed out no card state; If the client fills in 100 yuan of desires and buys 2 cards, at this moment, no corresponding 2 cards can be sold in the card case, will cause gulping down phenomena of the failure such as paper money, use to the client and cause very big inconvenience.

Invention constitutes

The purpose of this utility model is to overcome weak point of the prior art and provides a kind of and minimum card loading amount is set with the minimum card setting device that carries of the card vending machine that guarantees under any circumstance, the client all can normally purchase card.

The purpose of this utility model can realize by following approach:

The minimum card setting device that carries of card vending machine comprises card case and card-issuing device, and its structural feature is, also include sampler, comparison means and drive unit, and be electrically connected in regular turn, wherein the sample of signal end of sampler is connected with the card case, and the signal output part of drive unit is connected with card-issuing device.

So just can carry out minimum setting of carrying card: sampler subtracts counting and obtains residue card number the card number in the card case earlier, by comparison means the residue card number counted and the standard value that sets of comparison means inside are compared, this standard value is minimum card loading amount, when the overgauge value, then count again; When less than standard value, then drive card-issuing device and close by drive unit.

The standard value that sets can be the multiple of card face amount, like this, when blocking number less than standard value, will close card-issuing device, and the client can not be operated again, when preventing that the card remainder is not enough, and causes faults such as gulping down paper money.As: when the card face amount is 50 yuan, the set minimum card loading amount of comparison means is 2, if when the card of card in the case remaining 2 or 3, at this moment, buy 2 when the client fills in 100 yuan of desires, card vending machine still can normally be sold this card, after the sale, just remaining 0 or 1 of the card number in the card case is less than set minimum card loading amount, card vending machine will be closed card-issuing device, and the client can not be operated again.

The utility model can also further be specially:

Comparison means also includes comparer and data processing equipment, and the two is connected.

Comparer compares resulting numerical value of sampler and the standard value that sets, then comparative result is sent into data processing equipment, when fiducial value is that little (being that sampling value is less than standard value) then closes card-issuing device by drive unit, return sampler when fiducial value then sends signal for big (being that sampling value is more than or equal to standard value), carry out sampling next time.

Also include coin identifying device, it is electrically connected with comparison means.

Acting as of coin identifying device receives the Renminbi that the client imported, after differentiating affirmation, send a signal and pass through the data processing equipment of comparison means to drive unit, after the driving card-issuing device carries out the hair fastener operation, carry out card case card number sampling next time and handle by sampler and comparison means, when the card number carries card and is provided with less than minimum, comparison means will cut out card-issuing device by drive unit, close coin identifying device simultaneously, make the client can not import bank note again.

Also include display device, it is electrically connected with comparison means.

The effect of display device is to show the current state of card vending machine, when comparison means cuts out card-issuing device or returns sampler when taking a sample next time, send signal to display device, showing that current card has been sold finishes or sells card the present situation such as normally, so that the client understands the current state of card vending machine, and prevent situations such as maloperation.

Also comprise one drive circuit, it is plugged between sampler and the comparison means.

Driving circuit is used to handle sampled data and drives comparison means and compares operation.

Card-issuing device comprises driver and emerging device, and the signal output part of drive unit is electrically connected with the driver signal receiving end, the input end mechanical connection of output end of driver and emerging device.

After drive unit sent a signal and delivers to driver by signal output part, driver received this drive signal, promptly drove the hair fastener operation, by emerging device with card output that the client purchased.

Also include a control program, it is installed in the comparison means.

It is data analysis, judgement and the processing of handling in the operating process that this control program mainly acts on.Its workflow is as follows: card vending machine is under the normal condition, to judge whether reception bank note, if the input of no bank note, then enter comparing element, relatively block case card number and minimum card loading amount, when relatively being big, then indicate normal operating conditions, when relatively being little, then cut off card-issuing device, simultaneously the no card state of prompting; If the input of bank note is arranged, then carry out the card release operation, and the card number is subtracted bit manipulation, and enter comparing element.

Sampler comprises interface DISPEND1, driving circuit comprises chip UDN2595A, comparison means comprises chip ATMEGA103, wherein 2～9 pin of interface DISPEND1 are connected with 1～8 pin of chip UDN2595A respectively, and 11～18 pin of chip UDN2595A are connected with 61～54 pin of chip ATMEGA103 respectively.

Drive unit comprises chip SN74HC259N, card-issuing device comprises interface DISPEND2,35～39 pin of chip ATMEGA103 are connected with 1～3 pin, 13～14 pin of chip SN74HC259N respectively, and 4～7 pin of chip SN74HC259N, 9～12 pin are connected with 1～8 pin of interface DISPEND2 respectively.

Above-mentioned interface DISPEND1 and DISPEND2 are the self defined interface title, can carry out self-defined title to it according to user's custom.

In sum, advantage of the present utility model is: utilize central processing unit to carry out minimum card loading amount setting, thereby guarantee that card vending machine can normally use on the basis of minimum card loading amount, prevent to be not enough to carry out next operation at the remainder of card, and do not have when the client purchases card under the situation of any prompting, gulp down faults such as paper money.
