Embodiment Construction

[0047] The present invention proposes an on-line detection method for printed codes. The method includes positive number detection, and adopts multiple color cameras and a multi-channel parallel high-speed image acquisition and operation processing system. The high-definition images obtained by the color cameras are collected through digital image acquisition and Processing, and comprehensively judge the processed data, detect the printing defects of the online printing products, and issue corresponding control commands when printing defects are found, so as to conduct online detection and real-time monitoring of the printing quality of the front number of the online printing products. In addition, the present invention also proposes an online code printing detection system, which includes more than one detection unit, such as a front number detection unit, which uses multiple color cameras and a multi-channel parallel high-speed image acquisition and calculation processing syst...

Abstract

The invention discloses an online imprinting detection method and system. The system employs multiple colorful CCD (Charge Coupled Device) cameras and multiple parallel high-speed image collecting, operating and processing systems to detect and timely monitor printing qualities, including the front-side number printing quality, the front-side fluorescent pattern printing quality, the front and back side nominal value printing quality and the watermarking pattern printing quality (inverted note defect detection), for large RMB note products which are printed online; and the detection system emits a related command and an acousto-optic alarm signal the moment that continuous wastes or severe wastes are detected, thereby controlling an imprinting machine to stop running. Operation interfaces of different detection functions are integrated in a terminal display with a big screen for concentrated display, wherein the interfaces are clear, and operation is convenient. Number printing is the last procedure for RMB note printing, the printing quality detection after number printing can be used to verify defects detected in the previous procedures and intercept products missed in detection, thereby ensuring the quality of delivered products, and improving the production efficiency.

Description

technical field [0001] The invention relates to a post-code quality detection technology, in particular to an online code detection method and system. Background technique [0002] Number printing is the last process of RMB production, so there are usually very strict requirements on the quality of number printing. The number printing online inspection equipment developed in the early days of the printing industry uses a black and white CCD camera to image, and its detection accuracy is not high, and the detection function is not complete. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an on-line detection method and system for printed codes, which adopts multiple color CCD cameras and multi-channel parallel high-speed image acquisition and calculation processing systems, and is installed on the printing code machine to ensure the printing of printed products. Defects are detected online in real time. [0004]...
