Study And Implementation On The Rapid Analysis And Output System Based On Printed Test Data

"The rapid analysis and output system based on printing command test data" under the background of this thematic research project, according to the development requirements of the intelligent instrument system, in combination of development technologies on embedded Linux systems development, data analysis about Lex & Yacc, USB communication technologies and printing systems, this paper proposed a intelligent instrument system based on embedded Linux system and discussed the software implementation of the system.The main contents and results are shown as follows:Firstly, the original system output modes is improved , a new output system model was proposed in the article , reasearched and designed the new output system general structure, work processes and so on.Secondly , based on context-free grammar and context-sensitive grammar, raised a simple context-sensitive grammar to describe ESC PK stylus printer language , and raised the treatment to simple context-sensitive grammar in Lex & Yacc.Thirdly, Research and design the transformation from ESC PK printing sentence to PostScript document; Further analyzed the printing system correlation theories and realization technology, proposed printing system design model, implements the printing systems which have relatively perfect function and performance in the embedded Linux system.In this article, the study about the rapid analysis and output system based on print instructions test data in embedded Linux, processing mode and technical thinking has an active reference effort in which the PLA and China's existing equipment and technological innovation.
