A concealed fire optical fiber early warning method and system for an external wall fire-retardant insulation layer
By establishing a discrete graph structure and a graph connectivity search algorithm in the photovoltaic building composite facade, the heat from external photovoltaic equipment and the internal fire heat core of the flame-retardant insulation layer are decoupled, solving the problems of false alarms, missed alarms, and location distortion in the existing fiber optic fire alarm system, and realizing a high-confidence concealed fire early warning.

AI Technical Summary
Existing fiber optic fire alarm systems cannot effectively decouple externally attached heat shadows from the actual hidden fire heat core inside the fire-retardant insulation layer of photovoltaic building facades, leading to false alarms, missed alarms, and distorted alarm location.
By establishing a discrete graph structure that reflects the connectivity of the building interface, and combining projection dimensionality reduction operators and graph connectivity search algorithms, the heat from external photovoltaic equipment is decoupled from the internal fire heat core of the flame-retardant insulation layer. The graph connectivity search algorithm is then used to locate the hidden fire alarm points and output electrical alarm signals.
It improves the confidence level of early concealed fire detection, ensures that alarm signals have high confidence and accurate location basis, and reduces the probability of false alarms and missed alarms.
