Then it focuses on hardware design of control system with Intel 80C196KC and its corresponding circuit of operation, memory, man-machine interface, data collection channel, PWM pulse output, and communication interface etc. .
Based on the characters of IEEE-4888 bus bar and GPIB interface,data collection and collection format in DDL-III system are analyzed,software and hardware design for reconstructing the intelligent interface card used in CRT plotter with Printrex 820 plotting apparatus is described.
This article elaborates the background of constructing the geological data management system and makes an in-depth analysis on the demand of data users. Based on this, this article puts forward a detailed plan which is mainly about data flow, system framework and function, technology environment, interface, data collection and storage, software development etc. Thus the article does a useful research on the construction of geological data management system.
