摘要
本文分析了某厂引进的焊管生产线计算机数据采集系统SDC的工作原理、系统结构、硬、软件框图及设计中采用的先进技术:modula-2语言,灵活而海量的三级存储器;由索引表,系统文件配合RSX—11操作系统层次型数据库管理的灵活而可靠的方法……等等.同时指出了外国某公司在SDC系统设计中的错误——管号无法识别,致使该系统无法工作.
This paper analyses the working principles, system structure, the block diagrams of hardware and software and the advanced technique taken in statistic data collection (SDC) system, such as: Modula 2 language, flexible and huge memory with three levels, flexible and reliable management of the layered data base by key table, system file and RSX—11 operating system……and so on.
