Fire detection systems and methods
First Claim
1. A fire fighting control system comprising:
- a. a surveillance craft including;
(i) an imaging device, (ii) a controller coupled to the imaging device, and (iii) a communication circuit coupled to the controller;
b. a fire control headquarters having;
(i) a computer control system including a display system, a control program memory that stores a control program, and a database memory that stores data characterizing predefined fire control parameters for selected geographic regions of the earth, (ii) a first communication link between the computer control system and the communication circuit of the surveillance craft, and (iii) a second communication link between the computer control system and at least one fire fighting resource; and
c. wherein the control program includes;
(i) image acquisition commands that are executed by the computer control system to direct the surveillance craft to obtain and transmit to the computer control system image data defining images of selected geographic regions of the earth, (ii) image analysis commands that are executed by the command control system to analyze the communicated image data to determine whether a fire exists in a selected geographic region, and if a fire is determined to exist, to characterize selected features of the fire, (iii) database acquisition commands that are executed by the computer control system to locate and acquire from the database data defining fire control parameters characterizing the selected geographic region in which a fire exists, (iv) fuzzy logic analysis commands that are executed by the computer control system to analyze the data defining the selected features of the fire and the fire control parameters characterizing the selected geographic region in which the fire exists, and to render recommended fire fighting decisions, and (v) communication commands executed by the computer control system to control the display terminal to indicate recommended fire fighting decisions, and to communicate selected of the decisions to at least one fire fighting resource.

Abstract
A system and method for automatically detecting fires in select areas, and reacting thereto to put out the fires. A stationary, earth orbit satellite, pilotless drone aircrafts or piloted aircraft contains one or more infrared detectors and optical means for detecting small fires when they first occur in fields and wooded areas, preferably where man made campfires and trash dumping are prohibited. A computer in the satellite, drone or piloted aircraft and/or on the ground receives and analyzes image signals of the earth area or areas being monitored and, upon detecting infrared radiation of varying intensity and variable shape, indicative that a fire has started, generates coded signals which are (a) indicative of the coordinate locations of the fire, (b) the extent of the fire, (c) the shape of the area(s) burning, (d) the direction of movement of the fires (e) the speed(s) of the flame fronts, (f) smoke condition, (g) intensity of the fire, (h) fire ball location(s), etc. In one form, a conventional and/or infrared television camera(s) generates image or video signals which are digitized and recorded in memory and/or on tape or disc. Expert system logic, such as fuzzy logic, is used to prioritize dangerous areas to assist in directing fire fighting. Such information, or select portions thereof, is automatically transmitted to one or more earth bound and/or aircraft contained receivers where fire fighting equipment such as helicopter and aircraft containing drainable water or other fire fighting agents is available for immediate dispatch to the fire zone.
