| 摘 要： | 在瞬变电磁勘探中,需要在高压强电磁环境下采集电磁信号进行反褶积运算.如果模拟量与数字量之间没有电气隔离,那么高压很容易窜入低压器件并将其烧毁.设计了一个基于高精度线性光耦器件HCNR201双极性信号隔离转换电路,并介绍了高精度线性光耦器件HCNR201的主要特性及工作原理.应用于实际仪器的实验结果表明,该电路具有良好的线性度、准确度和适用性.

| Abstract: | Data acquisition in transient electromagnetic method(TEM) is in a high voltage and strong electromagnetic field.If there is not electric isolation between analog quantity and digital amount,the high voltage is easy to entry in the low voltage device and destroy it.A bipolarsignal isolation circuit was designed based on the features of the high-linearity optocoupler HCN201,and the working principle and the features of the high-linearity optocoupler HCN201 were introduced.The experimental results show the cir... |
