Abstract
With the rapid development of modern industrial technology, electrical parameter measurement, as an essential means for monitoring equipment operation status and fault diagnosis, directly affects the evaluation and optimization of system performance. Traditional measurement methods, limited by their strong hardware dependency and insufficient flexibility, are gradually unable to meet the complex and ever-changing application requirements. To address this issue, this study proposes an electrical parameter measurement technique based on virtual instrumentation, aiming to achieve intelligent and scalable measurement systems through software-defined approaches. The research employs the LabVIEW platform in conjunction with a data acquisition card to construct a virtual instrument system, utilizing signal processing algorithms for real-time acquisition and analysis of critical electrical parameters such as voltage and current. Additionally, an error correction mechanism is designed to enhance measurement accuracy. Experimental results demonstrate that this method outperforms traditional solutions in terms of dynamic response, measurement range, and cost-effectiveness, particularly exhibiting significant advantages in high-frequency signal measurements. The primary innovation of this study lies in the deep integration of virtual instrumentation technology with modern signal processing methods, overcoming the limitations of fixed functionality in traditional hardware and providing a flexible and efficient solution for electrical parameter measurement. Furthermore, this work lays a foundation for the intelligent development of related fields.
