| Abstract: |
| There are problems of the lack of unified specifications for the live detection and power outage test data of power grid equipment, low input efficiency and poor data reliability. Thus a system for automatic collection and verification of power grid equipment test data based on digital-analog normalization is built in this paper. First, a standardized model of power grid equipment test data and interface communication is proposed, including protocol automatic identification, data verification and protocol dispatch modules. The process of automatic collection and analysis of field data is designed to realize data exchange between instruments and data collection terminals. Considering the image characteristics of the power grid equipment detection test site, a high-magnification video compression coding technology based on content analysis is used to adapt to the differences in the imaging environment and achieve high-quality imaging. The hardware configuration and function realization of the data acquisition system are given. Finally, the feasibility of the design system is proved through the platform visualization application.
