计算机交流采样90°同步脉冲电路的研究
Research into Computer A.C Sampling 90° Simultaneous Pulses Circuits
【摘要】 针对将直流采样法改为最新的交流采样法.对产生90°同步脉冲的电路进行了设计和必要的理论分析,同时讨论了同步信号对遥测误差的影响。这两种电路经过计算机测试及实际应用.证明效果良好,它可使遥测的精度优于0.5%。
【Abstract】 To tackle the above mentioned problems, we use the method of new ac sampling instead of dc sampling. Our paper gives elaborate designs for the 90° simultaneous pulse circuit and theoretical analysis is also made.Meanwhile,we discuss the influence of simultaneous signals upon the error of remote control.These two kinds of circuits have proved to be quite effective through computer test and practical use. This can make the remote measuremeant more accurately by 0.5%.
