Designing and Realization of Bill Acceptor System based on Embed system
Zhang Jing-hu · Microcomputer Information · 2008
The main modules, such as image sampling, processing and identification, in identification system of RMB paper currency are designed and studied. Designing and applying of real-time data acquisition system of bill characteristic is a key issue of bill ac-ceptor system based on embedded system. According to the Characteristic of uclinux and S3C4510B, A real-time data acquisition system which uses interrupt is designed. And it can greatly improve the ability of concurrent processing of this bill acceptor system. size feature is chosen to identify the value of RMB paper currency images by the method of fuzzy reasoning which have been pre-processed Moment invariants are selected as features to recognize the orientation of RMB paper currency by RBF neural network .The validity and feasibility of the system are proved by experiments.
