2. CONTENTS Introduction Design Working Application Advantages & Disadvantages Conclusion Reference

3. INTRODUCTION Equipped With Specialized thermal sensors that detect that capture infrared radiation emitted by objects ,including fire. Fire fighters commonly use thermal drones. Providing real-time situational awareness, mapping the fire perimeter and identifying hot spots. The drone allows for easy fire extinguishing without risking life. The main draw back they can be challenging to fly especially in windy conditions. The cost of purchase and maintenance. The potential for interference with other aircraft, and the possibility of restriction in certain areas.

4. DESIGN The quadcopter is the most used UAV frame due to its simple structure. An x frame configuration is selected. The frame is designed in solid works. THE MAIN PARTS:- Propellers Drone controller BLDC Motor Drone frame Transmitter and receiver Power module Drone camera Dry powder extinguisher system Lipo battery

5. PROPELLER:- Drone Propellers provide lift for the aircraft by spinning and creating an airflow. Which results in a pressure difference between the top and bottom surfaces of the propeller. Types:-fiber,plastic etc.. DRONE CONTROLLER:- A device that allows a drone pilot to control a drone from the ground wirelessly. Drones have other controllers such as ESC , FIGHT controller . ESC :-Esc full form- electronic speed controller Devices that allow drone flight controllers to control and adjust the speed of the aircrafts electric motors. FLIGHT CONTROLLER:-The brain of the drone , which controls the motors and ESCs in the drone. It moves the drone by changing the motors RPM. BLDC MOTOR:- A brush less direct current motor is known as BLDC MOTOR. Is a small but power fully type of electric motor that uses direct current as its power source because of their size and efficiency.

6. Brushless Motors have an overall higher speed and torque and less noise than traditional brushed motors. Disadvatage is high cost DRONE FRAME:- The drone frame almost all UAV structures are made from carbon fiber composites. A drone frame is the structural backbone of a drone . It is the skeleton on which all other components are mounted and provides protection to all the electronics inside the drone. TRANSMITTER AND RECEIVER: - A transmitter is a necessary component of all electronic devices such as cell phones , ships , television stations etc.. They are also used for navigation purpose. A receiver is an electronic device that receives signals and radio waves that are transmitted by an transmitter .

7. The receiver extracts the message signal from the transmitted carrier signal. POWER MODULE:- Provide a regulated power supply for the flight controller, along with information about battery voltage and current. The voltage or current information is used to determine the consumed power and to hence to estimate remaining battery capacity. DRONE CAMERA: - Equipped with a thermal camera. Used by fire fighters to identify hotspot. Search the unsafe-building after the fire was extinguished. DRY POWDER EXTINGUISHER SYSTEM:- Put out fire by coating the fuel with a thin layer of dust separating the fuel from the oxygen in the air. A dry powder fire extinguisher forms a barrier that separates the oxygen Source and the fire . Parts: cylinders , pressure nobe , servo mechanism to operate the valve. LIPO BATTERY: - A lithium polymer battery (LIP0). Is a rechargeable battery that in the case of true Lipo . Uses solid polymer for the electrolyte and lithium for one of the electrodes. Three cell , voltage :11.1v .

8. The design of Commercial fire protection Systems Must meet regulations set by the National fires protection association (NFPA) ,the international building code (IBC) ,and any local standards . Need construction must also consider the needs for accessibility under the Americans with disabilities act (ADA). Designing a fire protection Systems for your business is truly an art. High rise security system is a leader in fire safety employing fire alarm designers and engineers working together to ensure your commercial fire protection system design is tailored to meet all architectural and fire code requirements

9. As you begin the design process keep in mind the main goals of a fire protection system –protect people lessen recovery time and property protection. The following steps will help you design a fire protection system that meets your specific building needs while achieving these main goals. Step 1 :code compliance This must be the first goal in any design because there are minimum legal requirements that must be met. The skipped professionals at HRSS will ensure that your commercial fire Protection system meets all required codes and standards and we go above code compliance to cater your security system to your unique building layout and operations.

10. Step 2: Fire Detection Solutions

An upgraded, modern fire protection system is the difference between detecting a small fire that is manageable or risking a larger fire that causes more damage.

Integrated fire protection systems combine fire detection equipment, modern monitoring equipment, heat detectors, and notification systems. These inclusive fire protection systems make it possible to detect high and low levels of danger for the fastest notification of fire from the start.

11. Step 3: Alarms and Notifications

An integral part of your commercial fire safety system is fire alarms. Fire alarms alert building occupants of danger but also alert emergency personnel for quicker response time. The technology of fire alarms can provide information to emergency personnel on the location and seriousness of the fire. This allows emergency workers to be properly equipped and dispatched to the exact location they are needed. Furthermore, alarms can play recordings that provide direction to your building’s occupants for a safe exit.

12. Step 4: Suppression of a

Fire

Sprinkler systems are the most common fire suppression tool. Sprinklers are used to contain fires until they can be put out and are a critical part of a suppression system design.

Another option is chemical suppression for buildings where using water is not an option, depending on the contents of the building.

13. WORKING The working principle of a drone is newtons third law of motion Identify hotspots and search the unsafe building after the fire was extinguished . The drone allows for easy fire extinguishing without risking life. Drone make use of foam casting pvc balls with dry chemical agents for extinguishing the fire instantly with a small blast. On coming in contact with fire the balls explode with fire extinguisher to put out the fire. The system makes use of 4 x drone motors coupled with a drone frame controlled by a flight controller to operate the drone in a stable condition.

14. MOTOR ROTATION AND MOVEMENT OF DRONE Clockwise and counter clockwise motor direction. The three movement of drones :- Roll : Move forward , backward, left and right. Pitch : Move up and down along a vertical axis Yaw : looking down on a drone from above movement of the drone clockwise or counter clockwise.

15. THRUST RATIO FRES>M×G :- Gain altitude FRES=M×G:- Hover FRES<M×G:- loose altitude Thrust:- To push or drive With force

16. APPLICATION Equip fire officials with the latest technology. Prevention during a fire spread in building ,home ,warehouse. Aerial surveillance and situational awareness. Real time data and visuals. Drones capture the dynamic nature of fires. Drones allow fire fighters to quickly and effectively scout out dangerous fires. Allows for safely extinguishing fires in high rise buildings forecast fires remotely dropping dry chemical fire extinguisher balls.

17. CONCLUSION The drones applications in industrial inspection, package delivery, agriculture and others are evolving at an enormous rate and expected to get better in future. It is important to invest in proper fire safety measures keep equipment and systems in good working order. Ensure that people are properly trained to handle emergency situations.
