Soc Trang students invent system to detect people trapped in fire

Help the fire department

Recently, fires, especially apartment fires, have caused heavy losses in human lives and property. "Apartment fires" has become the most searched keyword on the topic of fire prevention and fighting (PCCC).

According to statistics, from February 2022 to October 2023, there were more than 1,000 fires nationwide. In January 2024 alone, there were 376 fires nationwide, many people died, and more than 73 billion VND in damage.

Therefore, two students Lam Bao Tran (11A1 class student) and Lam Hung Vi (11A8 class student, Nguyen Thi Minh Khai High School for the Gifted, Soc Trang province) researched and created a "Warning and detection system for people trapped in apartment building fires".

"Through testing, we found that the project was initially successful and entered it into the provincial science and technology innovation competition, winning second prize (no first prize)," Lam Bao Tran excitedly shared.

Explaining the group's topic, Lam Hung Vi said: "The device created by the group has functions such as warning of fires through sensor signal recognition and navigation notifications to help people understand the situation.

The machine can detect survivors and trapped victims within each room through human recognition sensors, high temperature sensors and emergency buttons within each apartment.

According to Vi, the warning system is implemented in apartment buildings with many floors and many rooms. Each room will be equipped with a sensor (mounted on the ceiling or wall, inside and outside the house) with wifi connection to other devices in the apartment management department or connected to the smartphone of the device user.

When a fire breaks out, if someone is in the house, this device will identify whether the victim is in the room or outside and the device will automatically light up. At the same time, it will transmit information about the victim, room number, floor... to the apartment management department, fire fighting and rescue forces.

From there, people will proceed to rescue the victim from the danger zone.

The device is aesthetically pleasing and easy to use.

In other cases, when an accident occurs, if the victim is trapped inside a house with an emergency call device, the victim only needs to press the call button and the rescue team will immediately detect the location where the victim is trapped.

At the same time, the device also has a speaker system so that rescuers can encourage and guide victims through the initial steps to escape danger, waiting for rescuers to arrive to assist.

Wifi lost system still works

Lam Bao Tran added: "The system ensures the necessary factors such as stability and reliability; the price is only about 2 million VND, suitable for all families living in apartments to easily equip. Besides, the device is highly aesthetic and easy to use."

The system has a backup power source to provide wifi network, ensuring stable operation.

Commenting on the feasibility of the project, Lieutenant Colonel Bui Van Hong, Deputy Head of the Fire Prevention and Rescue Police Department - Soc Trang Provincial Police, said: "Through testing, the students' fire alarm system identified trapped victims, helping to determine the exact location of victims trapped in the fire.

At the same time, the system helps to accurately and quickly detect areas where fires and explosions occur so that building managers can notify people in the incident areas and neighboring areas.

The system uses a convenient management app for managers, who do not need to be constantly present at the location but can still grasp the situation if a fire or explosion occurs in the building.

The system uses wifi, however, to prevent power outages in case of fire or explosion, the students created a device that uses a backup power source to provide wifi to ensure the system operates stably.

We appreciate this model as very good and innovative in programming, creating a fire alarm system to find people and identify victims when a fire or explosion occurs.

The authorities highly appreciate this system.

This is also a very practical model, helping the Fire Prevention and Rescue force when arriving at the scene to quickly and accurately determine where the victims are trapped so they can approach as soon as possible, thereby bringing the victims out safely."

The system's objectives are to have a stable connection to the database (where data is stored on the website) via the internet from a 4G wifi transmitter; a stable speaker and warning light system; high performance in transmitting notifications, with the maximum recorded delay being 6 seconds.

The dashboard displays collected information intuitively and is easy to control. The hardware is optimized for mass production; the web-based dashboard is convenient to use and easily accessible remotely by users.
