Autonomous forest fire detection, alerting and mitigation for communities
View Patent ↗Various embodiments for an autonomous forest fire detection, alerting and mitigation device includes a subterranean data gatherer having a plurality of soil temperature and soil moisture sensors installed at a plurality of different depths in a soil. A data assimilator that has a configured threshold change depending on the plurality of different depths in the soil of the plurality of soil temperature and soil moisture sensors, the soil properties, the duration of the fire, and a time delay duration. The data assimilator receives a data transmission packet from the subterranean data gatherer and detects a fire and generates a fire alert when the plurality of soil temperature and soil moisture sensors all breach the configured threshold change. A smart water pump is also started to slow the fire or completely stop it. The subterranean data gatherer is installed at the plurality of different depths in the soil.
1. A device for forest fire detection comprising:
a subterranean data gatherer having a plurality of soil temperature and soil moisture sensors installed at a plurality of different depths in a soil; and
a data assimilator having a configured threshold change for said plurality of soil temperature and soil moisture sensors, said configured threshold change is defined based on said plurality of different depths in said soil of said plurality of soil temperature and soil moisture sensors, and
said data assimilator receives a data transmission packet from said subterranean data gatherer and said data assimilator detects fire and generates a fire alert when said plurality of soil temperature and soil moisture sensors have all individually breached said configured threshold change; and
said plurality of different depths in said soil of said plurality of soil temperature and soil moisture sensors is decided by said soil properties including thermal conductivity, thermal diffusivity, volumetric heat capacity, said soil type, said soil density and said soil porosity.
2. The device of claim 1 , wherein said configured threshold change for said plurality of soil temperature and soil moisture sensors, for said data assimilator, is defined based on a duration of time since a start of a fire.
3. The device of claim 1 , wherein said configured threshold change for said plurality of soil temperature and soil moisture sensors, for said data assimilator, is defined based on a time delay duration, wherein said fire alert will be raised when said plurality of soil temperature and soil moisture sensors all individually continue to breach said configured threshold change once said time delay duration is over.
4. The device of claim 1 , wherein said subterranean data gatherer is placed inside a subterranean data gatherer housing and said subterranean data gatherer housing is installed at said plurality of different depths in said soil and said subterranean data gatherer housing is made of fire-resistant materials and is waterproof.
5. The device of claim 1 , wherein said subterranean data gatherer is placed inside a subterranean data gatherer housing and said subterranean data gatherer housing is installed on top of a trolley platform installed at said plurality of different depths in said soil such that a handle of said trolley platform is above the surface of said soil to easily locate said subterranean data gatherer for any maintenance.
6. The device of claim 1 , wherein said subterranean data gatherer is placed inside a subterranean data gatherer housing wherein said subterranean data gatherer housing consists of a latch to perform maintenance.
7. The device of claim 1 , wherein said plurality of different depths in said soil of said plurality of soil temperature and soil moisture sensors is decided by said soil properties including thermal conductivity, thermal diffusivity, volumetric heat capacity, said soil type, said soil density and said soil porosity, and said configured threshold change for said plurality of soil temperature and soil moisture sensors, for said data assimilator, is defined based on said plurality of different depths in said soil of said plurality of soil temperature and soil moisture sensors.
