摘要
介绍了一种由微机控制的,用于核物理实验中的步进电机光电定位自动控制系统。并对硬件和软件的设计以及工作原理作了较详细的阐述。
This paper describles a system of automatic fixed position that consists of IBM486 computer and interface circuit. The interface circuit uses a programmable 8255 parallel interface chip and standard ISA BUS. This circuit board occupys one slot in PC which transmits data and control signal. The software was compiled by C language and operation adopts manmachine conversition. The rotary angle of rotation disk is controlled by a motor using photoelectricity fixed position signal. When rotation disk direcs at No.1 position the system collects sample and when rotaion disk direct at No.2 position it measures daughter nucleus. This method not only save time but also acquire data accurately. The system successfully was used in composition and research of superheavy new nuclear The experiment fully prove that operation of the system was stable and reliable.
