Computer System에 의한 산업용 DNC System에 관한 연구
박영식,오창주,Park Young sik,Oh Chang-ju 한국융합신호처리학회 2000 융합신호처리학회 논문지 (JISPS) Vol.1 No.2
Some evolutional system has been used to promote the efficiency of the DNC(Direct Numerical Control) Controller. However, these are many inconvenience to this operator because it lacks harmony in interaction between the computer and the NC(Numerical Control) Controller. Also, there are some controversial points when data error occurs at the Data Input/Output. Accordingly, this paper explores a new Data Remote Control System. In this study, the NC Controller of the DNC network has to get full data by removing data error in this system. In this system, the main merits are easy manufacturing and the convenience of Data Input/Output. That is, remote control of the NC machine tool is possible without mutual interaction between the computer and itself.

Water supply system in modern society is one of the most important urban infrastructures as a life line stippling necessary amount of treated water to meet living standard and proper operations of city organizations and urban facilities according to social development and economic growth. The purpose of this study is to analyze the water supply and distribution systems in small cities in Korea and to suggest the enhanced maintenance and the management methods of those facilities. The data from the city of Namwon was analyzed and following result are obtained. Leakage may has been occurred out of pipe network but, the area of high elevation has a little lack of water because the low pressure prevails in the distribution pipes. In order to secure the stabilized water supply to those area the distribution tank are required and the downtown area of the city having problems with water supply needs to adopt the concept of block type pipe network with profound research whereas the new developed area of the cities should utilized the concept of the blocked type pipe network from the beginning stage of development.
