Key Features

Real-time Dashboard: Collect 28 sensor data points at 1Hz and visualize with multi-axis charts
P&ID Screen: 25+ equipment components implemented as SVG with real-time status reflection and integrated control
Protocol Editor: Drag-and-drop operation sequence editing with loop/delay support and real-time execution monitoring
Alarm/Event Management: 5-category classification, individual/bulk acknowledgment, audit trail preservation
Multi-Project: Isolated databases per experiment/operation for data separation

Key Achievements

Embedded MQTT Broker: Aedes integrated into Electron for offline operation without external server
Message Integrity Verification: Real-time hardware communication spec (ICD v2.0) compliance verification with Zod schemas
Multi-Project DB Isolation: Independent SQLite DB per project for experiment/operation data separation
High-Performance Concurrency: WAL mode + read/write connection separation for stable processing of 86,400 daily telemetry records
Time-Series Data Optimization: 5-tier aggregation tables + LTTB downsampling for sub-100ms queries on 7-day data
Non-blocking Export: Worker Thread-based CSV export preventing communication/UI blocking during large data processing
Protocol Safety Validation: Loop validity checking to prevent infinite loop/nesting errors in advance
