Technical Principles

Technical Principles
The core working principle is based on modular testing integration, combining automated data capture and processing with manual wiring for high-voltage test items.
Implementation Workflow
1. Use a test cart for one-time wiring to complete DC resistance and ratio tests, with data automatically uploaded to the central management system.
2. Conduct manual wiring for no-load, load, and withstand voltage tests, which are automatically executed by the system with standardized report generation.
Core Architecture & Innovative Design
1. Test Cart Module: Reduces wiring workload by 60% through one-time connection for core tests, improving operational efficiency.
2. Central Data Management Module: Automatically records all test data, eliminating manual errors and ensuring full traceability for quality audits.
