带信号隔离的高精度测量系统

High precision measurement system with signal insulation

本文介绍了一个高精度信号测量系统的实现,并根据系统的设计要求,对隔离电路的位置进行了转移,达到简化信号隔离模块的目的。同时对在测量过程中如何提高信号测量精度、抗干扰及进行系统校正方法做了有益的探索。实际使用结果表明,本系统的设计实现兼顾了降低成本和提高性能两方面的要求,达到了良好的应用效果。

In this article, a precision measure system is presented. Especially, a method to simplify signal insulation is given. This goal is approached by migrating the insulation circuit. A valuable way to raise the measure precision and to correct system error was demonstrated. It has been proved that design of the system has given attention to both low cost and high performance.
