Project Objective:
Accidental fires may cause severe bodily harm and destruction of property. General Fire mishaps are often unexpected and abrupt. Therefore, Drone can assist firefighters in determining where to focus resources and how to approach and enter the situation. A fire extinguisher ball installed on a drone may be used in emergency situations when human assistance is impossible. The Fire Ball dropped into the Flame, where it activates and disperse a dry powder Fire Extinguisher agent. This fire extinguisher is effective against A, B, and C class fires. Thus defining the main objective of our drone that is to extinguish fire with the help of fire extinguishing ball.
Problem Statement:
We are dealing with a real-world problem. Fires have led to huge losses of life and property throughout history. Having a quick access to fire and instant extinguishing is key to countering fire threats. Here are the problems firefighters face in various situations:
Forest Wildfires: Wildfires that start in central forest areas are difficult to get to and by the time firefighters reach there with water tanks/ fire brigade vehicles the fires already spread to other areas.
Fires in high buildings: Fire fighting vehicles provide water for spraying on high building fires leading to heavy losses.
Fires in homes: Fire fighters need to manually get into homes and fire emergency areas risking their lives to put out those fires.
To help in all of the above situations we here propose to design a firefighting drone that can solve all these problems. The drone allows for easy fire extinguishing without risking life. Also, it can access forest areas in an instant which would require hours for fire trucks or humans to arrive at and instantly reach high building windows with fire extinguisher ball.
As there are many fire incidents which causes huge damage to constructed Buildings and many humans who end up their life in such kind of incidents. A drone with no aerial traffic can get on the scene and can extinguish those fires with less human involvement to save valuable human lives.
Socio-Economic Benefits:
Firefighting is a difficult task, as many fire fighters lose their lives trying to extinguish a fire. Some fires have even erupted out of control in the forest. which endangers the lives of many fire fighters who are trying to extinguish it. A drone in this scenario is just a machine fighting a fire incident, which with less human involvement can control fire accidents. Many new features can be added to the drone. These can be manufactured on an industrial level and can be given to the fire department. So, the firefighting UAV can put out or control big fires with less damage to people, buildings, nature, and the firefighters.
Project Methodology:
The Drone is Designed to have Hexa-copter Configuration, only then the required amount of Thrust will be produced by the rotors. The flying part which includes the drone frame, motors, propellers, and other components, is common to other drones, but with high payload carrying capacity. A RF transmitter will transmit a signal which will be received by the receiver of the drone. Then, the signal goes to the FCB where it sends the received and processed signal to other electronic sensors. Also, FCB have inbuild accelerometer and gyroscope sensor, which would be used to balance off the motors thrust difference after dropping the ball and will keep the drone stabilized mid-air.
With the aid of the Mission planner software, the most recent firmware is installed on the flight controller board based on the configuration specifications (hexa-copter). Performed calibrations on the drone's accelerometer, magnetometer, electronic speed controller, etc. prior to flight. We installed the Fire Ball Dropping Mechanism, and, with the help of an RF Controller, the mechanism can be controlled. The Mathematical Model with its control system was also designed on MATLAB, and to test the structure of the drone, certain tests were performed on the frame of the drone through ANSYS.
Conclusions:
The drone has been intended to carry a maximum payload of 1.5 kilograms for a duration of 15 minutes. It decreases the danger faced by firefighters engaged in firefighting operations. Drones must become intelligent and quick-witted so that they may improve industrial processes, maximize their value, and be extensively used in future industries. If greater attention is placed on these requirements, they may be met in engineering, maintenance, management of essential infrastructure, and asset management. Implementing drone systems into an industry may provide new prospects and novel business models. There are just a handful of drone startup firms in Pakistan, and they are attempting to integrate this revolutionary technology into their systems to make their operations safer, more dependable, and more predictable. Automotive sector deployment of this technology may be excellent from an industrial standpoint.
