线性插值法用于光测高电压的探讨

Research on Optical Measurement of High Voltage Using Linear Interpolation Method

在分析目前光测电压研究中系统设计特点及其存在的问题的基础上,提出了旨在消除零点温漂、扩大系统动态范围、减小非线性误差的光测电压新方法——线性插值法。同时给出了用于光电信号处理的单片机硬件框图和程序框图。最后,对该方法之中的几种主要的系统误差进行了分析。

This paper, after discussing the feature of system destign and problems of the present optical voltage measusing system, puts forward a new method——linear interpolation——by using monolithic computer, aimed at the elimination of the zero—point temperature,drift, expansion of the measuring Tange and reduction of the non—linear error of the system. Meanwhile the hardware structure flowchart and the program flowchart of the monolithic computer are given, along with the quantitative analysis of the main errors of the system.
