Smart firefighting, preventing fires from "burning"

Recently, a fire broke out in the China Telecom Building in Changsha, Hunan Province. According to the video on the Internet, thick smoke billowed from the scene, and some items with fire were falling. The dozens of floors burned violently, and only about 10 minutes passed after the people in the building escaped. , the fire has spread to the upper floors, but fortunately no one was injured.

In the face of fire, the most common and prominent accident that poses a huge threat to the safety of people's lives and properties, the industry has long been pinning its hopes on various solutions to prevent unburned fires.

Nowadays, with the development of Internet of Things, artificial intelligence, virtual reality, communication and other technologies, fire protection is becoming more and more intelligent, and concepts such as Fire protection of Internet of things and smart fire protection have emerged.

Compared with traditional firefighting, smart firefighting has huge advantages in the collection and processing of multi-dimensional data. It pays more attention to opening up information islands between different systems, and widely uses sensing equipment to collect data including smoke, temperature, inductance, and fire hydrants. Various types of data such as hydraulic pressure and fire pool water level have improved the ability to sense and early warning. Through various technical means, the fire situation can be detected earlier, and then the collected data will be transmitted to the cloud through NB, LoRaand other technologies, so that equipment, water Elements such as resources and firefighters can be analyzed in a real-time, dynamic and integrated manner, so as to make faster fire-fighting decisions, rationally dispatch all surrounding fire-fighting resources, and minimize the risk and impact of fires.


For fire prevention, it can be roughly divided into two major scenarios: indoor and outdoor.

In indoor scenarios, the most commonly used sensor for firefighting IoT or smart firefighting is the smoke sensor. Whether you are in the office or at home, you can basically find the smoke sensor when you look up. With the advancement of technology, the traditional independent smoke sensor can no longer meet the new market demand, and the intelligent smoke sensor solution that can be linked will follow.

Through the linkage between the sensor and the automatic fire alarm system, when there is a fire, it will play a role with other systems in the building through BIM. For example, the non-fire power supply needs to be cut off in the event of a fire. This instruction can basically be completed by the automatic fire alarm system. At the same time, the relevant information of the fire will enter the fire control room or the corresponding graphic display device; if it is connected to the unified Internet of Things cloud platform of the public sector, the information will also be processed in time, and the relevant personnel will be notified in time.

For outdoor scenes, fire hydrants are the main source of water for fire fighting in cities, and are also an important part of urban public firefighting facilities, including above-ground fire hydrants, underground fire hydrants, and water cranes, which can be seen at almost every distance on the street to once. When a fire occurs, everyone will feel a sense of crisis, and when there is no fire, if they have not experienced a fire, it is often difficult for ordinary people to pay enough attention to fire protection. For equipment such as fire hydrants, they are not often used or even left idle for a long time. To ensure their effectiveness, they can only be checked regularly by assigning personnel, which is a large cost in terms of cost. In the Internet of Things, plug-and-play wireless communication modules that do not require wiring in the Internet of Things field can be effectively solved.
