测差 meaning in English

error of measurement

So to develop a new type of transformer calibrator which has the high precision and the high degree of automation is significative . for the outdated transformer calibrator is widely used , this paper analyzed the theory of previous calibrators and proposed an idea of designing a new type of intelligent calibrator , based on the theory of measure the difference , adopt the project of dsp and mcu structure , also use high speed a / d electric chip . after the design of hardware circuit diagram , adopt the theory of fft and quasi - synchronous sampling method to reach the demand of precision . this paper discuss the intelligent development of transformer calibrator , achieve some success in the study
本文针对国内市场目前普遍使用的老式互感器校验仪的现状，提出了智能型互感器校验的研制思想，并详细讲述了其理论依据和实现过程，提出了切实可行的方案：基于测差测量原理，进行基于dsp和mcu双cpu架构、并采用高速a / d的硬件电路设计，并在此基础上采用快速傅立叶变换和准同步采样算法，并完成相关的软件算法框图设计，对互感器校验仪的智能化发展进行了有益的探索，取得了具有实用意义的成果。
