마이크로컴퓨터를 이용한 온-라인 측정 시스템의 개발 Development of microcomputer-based on-line measurement system

An inexpensive and very simple microcomputer-aided measurement system has been designed for on-line experiments, which perform simultaneously data acquisition, data recorditing, calculations with the data, and positioning of necessary sensors. Interfacting between the microcomputer and the data acquisition board which consists of A/D converter, analog multiplexer, and sample-and-holder, etc. has been done through IEEE-488 interface port and parallel user port both provided by the PET computer"s main logic board. Data and control signals are transfered between devices without handshaking. By utilizing BASIC commands PEEK, POKE, SYS, USR which are offered by PET microcomputer, it is possible to link machine code subroutines into the main BASIC program. This facilitates ease of data transfer, programming, and speedy execution of the program. In addition, an X-Y scanning table has been concected to the system in order to automatically position measuring sensors along a pre-determined path of interest.
