This project proposes a solution to counteract fires in decks made of dry organic material, replacing smoke, temperature and flame sensors with a video camera solution. For this purpose a scale model of a structure covered by dry organic material was implemented, where the presence of a fire is detected that is captured by a camera and analyzed by an engineering station. As an engineering station there is a Raspberry Pi 3, which evaluates a series of rules based on the RGB and YCbCr color components of the images captured by the camera for the classification of fire pixels; Subsequently, control actions are executed according to design criteria. To control the fire, there is an electrovalve that is operated by a control signal emitted from the engineering station, giving way to the water flow through a pipe that finally irrigates the cover by means of a sprinkler. The device's response to real fire situations is evaluated through a series of tests that help determine just how accurate, precise, and sensitive it is overall. The designed device has a percentage of 98% of fire detection and 12% of false alarms, fulfilling satisfactorily with the desired operation, since it detects, notifies and controls the presence of a fire that is present in a cover of dry organic material, Thus minimizing the losses that may occur in the event of catastrophe, where the main author is the fire. |
