Description

Technical field

The utility model relates to a card counting machine, in particular to a multifunctional card counting machine.

Background art

The existing card counting machines are special equipment specially designed for counting tickets or cards at places like metro stations, highways, supermarkets, tourist attractions, etc. The wheel-type card counting machines have a high-accuracy sensor that could accurately and precisely feeding, conveying, and counting cards; the counting mechanism can be preset, and automatically stopped when it reached the preset value; it can be used for tickets or cards that are larger than 0.46mm, regardless of the materials they made of; the machines will stop operating whenever there is a malfunctioning, such as cards jammed during the counting process, and it will display the particular fault type; these card counting machines are widely used in metro stations, highways, or places in which require counting a massive volume of cards. Since cards are unified in the same specification and the information on each card has no difference, therefore card counting process will become more convenient by adopting the card counting machines.

In the banking industry, tellers need to make daily count on both cash and debit cards that are distributed from a card making center to each branch. Cash counting machines can be used to count the cash, but card number information cannot be acquired as only bank cards are counted. If card numbers need to be acquired, operators must use an IC module in order to do so, which is labor-intensive, timeconsuming, low in efficiency and also prone to errors. In view of the above reasons, equipment for recognizing bank card number is developed, and OCR is utilized to recognize the numbers of physical cards, achieving the purpose of band card counting and card number output.

Invention content

The utility model aims to solve the problems in the prior art and provides a multifunctional card counting machine which can utilize OCR to recognize the numbers of physical band cards, achieving the purpose of band card counting and card number output.

In order to solve the above technical problems, the utility model adopts the following technical solution:

A multifunctional card counting machine, which is characterized in that it is composed of a card feeding slot, a card conveying unit, an image acquisition module, a recognition module and a card receiving unit; the card feeding slot is connected with the inlet of the card conveying unit; the image acquisition module and the recognition module are sequentially arranged on the card conveying unit along the conveying direction of the cards, and the tail end of the card conveying unit is connected with the card receiving unit.

The card feeding slot is a long passage.

A stepping motor is arranged on the card conveying unit which can count the cards and convey them to the preset position; the stepping motor transmits signals to the scanner to start it, and the scanner starts scanning card numbers to acquire image of the front of each card; the images are accurately analyzed and then converted into documents; and the software system outputs the acquired information and reasonably receives and stores the cards in the card receiving unit.

The image acquisition module is a charge coupled device (CCD). Tens of thousands of photoelectric triodes are integrated on a silicon single crystal, and the photoelectric triodes are divided into three columns and covered by red, green and blue color filters respectively to realize colored scanning. The photoelectric triodes can generate current when being irradiated by light, and the current is amplified and then output. When a light source of the scanner passes the cards, card images are transmitted to the CCD by using a mirror face; the CCD converts brightness signals into electric signals, and then data information of the images is obtained through analogy-digital conversion. The scanning light source continues moving to scan nextcolumn images of the cards till moving to a scanning range boundary preset by a user.

The recognition module is optical character recognition equipment. Automatic recognition of characters is realized on the basis of scanning technology in the image acquisition module. After receiving reflective light signals on a paper plane, the OCR inside circuit recognizes the characters and inputs character codes into a computer.

The optical character recognition equipment (OCR system) structurally comprises a scanning input module, a character segmentation module, a character recognition module and a post-processing module. Document images containing the characters are acquired through the scanner and then segmented into independent character images by the character segmentation module; the character recognition module extracts features of the characters, which are recognized by a recognizer; finally the post-processing module corrects errors of recognition results according to language knowledge. The recognition process of the system starts from image scanning, so the scanning input stage is a foundation of the whole recognition system. If regular lead print characters are recognized, the characters can be generally recognized by utilizing a method of superposition comparing with reference images without extraction of features from the character images. If handwritten characters are recognized, corresponding character features are extracted by utilizing a contour tracing method. The extracted features serve as a basis for recognition, such as length, angle, end point, distribution and surrounding features of strokes, which are expressed in a form of multidimensional data. Learned graphs serving as recognition criteria are stored in a recognition dictionary in the form of multidimensional vectors.

According to the multifunction card counting machine, the conveying unit is utilized to feed the cards; the cards are counted accurately and the front images of the cards are scanned; OCR technology is utilized to recognize lithoprint or embossed card number portions, and the card number information is output in xls/txt format, achieving the purposes of converting image information into document information. In addition, the multifunctional card counting machine can also directly recognize IC card information and read card number information for display.

The multifunctional card counting machine has the advantages that the images scanned by the multifunctional card counting machine have high quality and certain depth of field, and the card counting machine can scan uneven objects; due to low temperature coefficient, and the change of surrounding environment temperature is negligible for common work. Graphs in images continue to be stored, and information in forms and characters in the images are all converted into computer characters, so that storage capacity of image information is reduced, and the recognized characters can be reused and analyzed, and of course, manpower and time for keyboard input are saved. In addition, accurate counting can be realized, so that the multifunctional card counting machine is a qualitative leap in statistical recording work.

The multifunctional card counting machine brings convenience to bank tellers to timely acquire card number information, and greatly improves daily work in banks. It has overcome the defects of labor consuming and high error rate of manual input of the information into computers and realizes high-speed and automatic input of information like characters and images. A noncontact IC mode and in-card power-free and contactfree technology are adopted, so that the security of bank cards is ensured. The product provides the card counting machine and related system software tools, so that bank card number counting can be performed daily; the card counting machine can be connected with the computer through an interface to achieve subsequent data sharing, recording and printing. The multifunctional card counting machine has a quite wide practical range, high practical value, and is worthy of being vigorously popularized and applied in other standard card industries.
