摘要
本文主要论述了计算机控制系统在解决高压环境下采集小电流信号的一种尝试,这种方法巧妙地利用了霍尔元件的输入输出特性,在采样点和输出之间运用了电磁隔离,使得高压环境下的数据采样安全、可靠,且线性度较好。
In this paper an attempt on resoving the problom
of the acquisition of low current signals in the high voltage
is discribed.By using the I/O characters of Hall elements,
the acquisition points separated from output is ingeniously
realized by electromagntic so that he data acquisition in the
high voltage is made safely,reliably and best linearly.
