Abstract
An automated fire detection system includes a distributed network of standalone sensor units having mulifunctional capability to detect wildfires at their earliest stage. Multiple modes of verification are employed, including thermal imaging, spectral analysis, near infrared and long-wave infrared measurements, measurements of the presence and/or concentration of smoke, and sensing local temperature and humidity and wind speed and direction. A dedicated algorithm receives all data from the network and determines the location of flames from the imaging sensors, combined with the smoke, temperature, humidity, and wind measurements at every dispersed device.

An automated system for monitoring a large area and detecting dangerous fire conditions as they develop, including:
- a plurality of data acquisition assemblies directed to surveil the area, each including a plurality of sensors adapted to detect emissions that may be indicative of a dangerous fire condition;
- said data acquisition assemblies further including communications devices for mutual transfer of the output signals of said sensors;
- an artificial intelligence network for receiving said output signals of said sensors and analyzing said output signals to determine if a dangerous fire condition is occurring.
A method for monitoring a large area and detecting dangerous fire conditions as they develop, including the steps of:
- initially imaging the area in two or more different near-infrared bands;
- calculating the ratio of the near-infrared images to detect any potential fire emissions and eliminate spurious non-fire sources;
- surveilling any detected potential fire emissions using sensors operating in the visible band and near-infrared band;
- calculating the ratio of the visible and near-infrared emissions to determine if a potential fire condition is being detected;
- surveilling any detected potential fire emissions using a long-wave infrared thermal imaging camera to detect a dangerous fire condition.
A data acquisition assembly for monitoring and detecting dangerous fire conditions, which may include a solar panel, Wide Area Network (or equivalent) wireless connection unit, rechargeable battery, smoke sensors, temperature sensor, humidity sensor, wind direction sensor, thermal imager, imaging cameras, near-infrared and visible diodes, narrow-band filters, at least one microcontroller, GPS locator and a memory card.
