Design of a Page-Checking Instrument Based on Fuzzy Pattern Recognition

In this paper, a page-checking instrument via MCU Atmega128 and fuzzy pattern recognition theory is developed for automatic bookbinding machines. This instrument detects dynamically wrong pages locating in many word pages, graphic pages and word-graphic pages, and at the same time, takes a message to automatic bookbinding machine that lets wrong pages pass as soon as receiving the message. This instrument can communicate with computers by RS232 protocol, too. A detecting algorithm developed via fuzzy pattern recognition theory is stored in page-checking instrument. And this instrument detects wrong pages by two detecting modes, one is self-adaptive detecting mode, the other is non self-adaptive detecting mode. Experiments show that precision of this wrong page-detecting instrument is 0.5%, and possess fine stability
