Data acquisition and control system for lead-bismuth loop KYLIN-Ⅱ-M

Among different heavy liquid metals(HLMs), lead-bismuth eutectic(LBE) is considered at present as a potential candidate for the coolant of new generation fast reactors(critical and subcritical) and for liquid spallation neutron sources and accelerator driven systems(ADS). A high temperature liquid LBE loop, KYLIN-II-M,has been built to study the characteristics of corrosion and fluidity of LBE at the Institute of Nuclear Energy Safety Technology. However, due to the sensors and execution components of the loop work at high temperatures and in severely corrosive environments, the reliability and security of the data acquisition and control system(DACS) of KYLIN-II-M face challenges during the loop operation. In order to meet the urgent needs for KYLIN-II-M’s long-term stable operation, a virtualization and redundancy control system has been developed.The onsite operation result shows that the DACS is stable and reliable. In this paper, the experimental results are described in detail.     

基于STC单片机的弹丸速度测量系统设计

设计了一种速度大于1 km/s的高速弹丸测速装置。用光纤将入射光导入至弹丸表面,将其反射光导出至光电二极管（GT101）,利用光电转换后的信号触发STC12C5A60S2单片机计时器两路外部中断实现计时,根据两测量点间距和弹丸飞行的时间差,可计算弹丸速度值。利用单片机控制LCD显示速度值并作为下位机与上位机进行串行通信。将软硬件系统经集成为光电测速装置,并用于二级轻气炮的高速弹丸速度测量。结果表明,该测速装置简单可靠,可满足二级轻气炮宽范围速度测量的要求。
