Solution Approach 1:

The patent creates a universal remote monitoring system that can serve multiple turbine engines across an entire fleet through a single centralized server. This multi-functional architecture allows one server to analyze data from numerous engines simultaneously, achieving fleet-wide surveillance coverage without requiring individual local systems on each engine, thereby dramatically reducing implementation time and cost.

Inventive Principle:
