Analysis and Design of a Novel Integrated Automatic Verification System Software Platform

Abstract

In order to study the intelligent verification system of microprocessor-based relay protection tester, a novel software platform of integrated automatic verification system is designed in this paper. First of all, the composition and principle of the verification system are introduced, and then the communication between the relay protection tester and high precision AC-DC meter whose entire closed-loop system is completed theoretically. The software platform adopts the design concept of layering and modularization. Through the program generation platform layer, the verification schemes of relay protection tester under tested with different voltage and current output channels are completed to edit and design. Through the hardware interface layer, the communication modules of driver module and verification system of relay protection tester under tested are complete to design. Through drive modules of tester, analog voltage and current output are completed. Through communicating with high-precision meter, the reading of measurement is completed. And also, the calculation and result judgment of measurement error and test report generation are intelligently completed. The designed platform implements to automatically verify microprocessor-based relay protection tester, which greatly improves the efficiency of the verification system.
