Design of the Embedded RLC Measurement Module

摘要

Based on the frequency measurement principle, an embedded RLC measurement module was designed in this paper. By the RC oscillator circuit and LC three-point oscillator circuit, the R, L, C analog parameters can be converted into a digital frequency for single-chip computer processing, according to the relationship between a function of frequency and component parameters, the RLC components corresponding parameter values is calculated. Experimental results showed that the RLC module has an automatic conversion range, high precision, enabling network connections and so on. It can be applied to management and fault monitoring and forecasting power transmission lines, oil and gas pipelines and submarine cables and other important public facilities.
