Abstract

This invention relates to the banknote serial number processing method and its device. Including: banknote serial number recording step, that is to convert the banknote serial number into image signal by using image capture device; banknote serial number recording decoded step, i.e. processing the banknote serial number image signal by filtration of image signals, A/D conversion, synchronizing separation and then stored in memory unit; banknote serial number digital signal processing step, the signals from image memory unit are processed for recognition, the bundle code and banknote serial number are stored into digital memory unit and output for later use; the comparison banknote serial numbers read-in steps, reading banknote serial number from a certain bundle code to be compared, then sent to read-in memory unit; comparison step for the banknote serial number to be compared and newly recording banknote serial number comparison, to compare the newly recording banknote serial number with each of the banknote serial number from the reading-in memory until there is a match and an alarm signal is sent out. Application of this invention can impose a strict strike upon the crimes such as robbery of money from bank saves, robbery of cash transport vehicles or kidnaps, and cash counterfeiting.

Claims

1. A banknote serial number processing method, its features include:

1) Banknote serial number recording step, that is to convert the banknote serial number into image signal by using image capture device;

2) Banknote serial number recording decoded step, i.e. process the banknote serial number image signal by filtration, analogue-digital conversion and synchronizing separation and store images signal in image memory unit;

3) Banknote serial number digital signal processing step, which is used for the stored image recognition processing, identifying the bundle code and storing banknote serial number and bundle code in digital memory and Outputting for later use;

4) Reading step for banknote serial number to be compared, that is to sort out corresponding banknote serial number from the bundle code to be compared, then store the serial number in reading-in memory unit;

5) Comparison step for the banknote serial number to be compared and newly recording banknote serial number comparison, which will compare the newly recording banknote serial number with each of the said banknote serial number from the reading-in memory until same serial number coincides and an alarm is activated.

2. The banknote serial number processing method according to the claim 1, characterized in that the obtaining step of newly recording banknote serial number repeat the above steps 1) to 3).

3. The banknote serial number processing method according to the claim 1, characterized in that the bundle codes can be printed or bar-coded type attached to banknote bundles.

5. The specific device of the banknote serial number processing method according to the claim 1, characterized in that the digital signal processing unit (5) has recording and comparison programs.

6. The specific device of the banknote serial number processing method according to the claim 5, characterized in that the recording program'"'"'s flow procedure is as follows:

starting, formatting, setting the cash note number as zero;

reading image from the image memory unit;

judging if it is valid image, if not, ending the program;

if it is valid image, Gauss filtration, modified projection location and digital mode mask processing are used, the serial numbers are rectified and converted to binary data, and then their structures are identified and output;

add one to number of cash note;

judging if the cash note is 100, if so, bundle up the banknote and assign a bundle code to the bundle, output the bundle code, reset the cash note number to zero and go back the above steps from the step of reading image from the image memory unit;

if the cash note number is not 100, the system goes directly back to the step of reading image from the image memory unit.

7. The specific device of the banknote serial number processing method according to the claim 5, characterized in that the comparison program procedures are:

starting, formatting, setting cash note number to zero;

reading the image from the image memory unit;

judging if the image is valid, if not, ending the program;

if the image is valid, Gauss filtration, modified projection location and digital mode mask processing are used, the serial numbers are rectified and converted to binary data, and then their structures are identified and sent out and compared with the stored possible robbed banknote serial number, when same serial number is found, signaling an alarm and ending the program;

if there is no same serial number, adding one to cash note number;

judging if the cash note number is 100, if so, bundling up the banknote and assigning a code to the bundle and output the bundle code;

resetting cash note number as zero and going back the above steps from the step of reading image from the image memory unit;

if the cash note number is not 100, returning directly to the step of reading image from the image memory unit.
