Fiber Optic Detection System for Early Fire Localization

The patent replaces the mechanical pipe network transport system with an optical detection system. Fiber optic cables with light sources and sensors directly detect smoke particles at distributed nodes throughout the protected space, eliminating the need to physically transport smoke samples through pipes to a central detector. This substitution of mechanical transport with optical detection resolves the contradiction by providing both wide coverage through distributed nodes and immediate detection without transport delays.

The patent divides the protected space into multiple zones with distributed detection nodes, each containing fiber optic cables with light sources and sensors. This segmentation allows simultaneous detection across the entire coverage area rather than relying on centralized pipe network collection, thereby achieving both extensive coverage and immediate detection response at each location.

The patent replaces the pipe network air sampling system with distributed optical detection nodes that directly measure smoke particle concentration at each location. By using fiber optic cables with light sources and sensors positioned throughout the protected space, the system detects smoke in situ without mixing with clean air from pipe network sources, thereby maintaining both wide detection coverage and accurate smoke concentration measurements.

The patent introduces fiber optic cables as intermediary elements that transmit light through smoke particles to detect their presence and concentration. These optical intermediaries enable direct measurement of smoke at distributed locations without requiring physical air sampling and transport, thus avoiding dilution effects while maintaining detection coverage across the entire protected space.
