Description

Fire escape guidance and search and rescue assistance systems, as well as Survival Information Application Methods

The invention relates to the technical field of escape/rescue equipment at a fire scene, in particular to a smoke detection device, a fire escape guidance system, a fire search and rescue assistance system, and a Optimization method to improve survival rate in fire scene.

In daily life, various disasters occur constantly, and among them, fires are the most frequent. When faced with a fire scene, the general public is usually helpless and can only rely on the rescue of fire and rescue personnel. The most terrible place for fire is often in the middle of the night or in a place with no one. If the fire is not detected early, it will often spread. It will become a fire and cause heavy casualties. It is often heard that in the early stage of a fire, due to the careless operation of the fire extinguishing device, the fire spreads or an irreversible fire occurs in an unmanned place. In fact, these can be reduced and avoided by the power of technology, such as the safety of the Haishan Coal Mine in the early years. When the personnel discovered the fire, they threw the fire extinguisher into the fire because they could not operate the fire extinguisher, resulting in irreparable heavy casualties. In the Taichung ALA nightclub, when the fire broke out, the fire extinguisher could not be found and the fire extinguisher did not know how to use it, which also caused several deaths and many injuries. Therefore, the fire-fighting principles promoted in the MRT stations of the Taipei MRT Corporation are to put out the fire, notify the escape, and put the fire-fighting as the first priority. With the trend of more and more emphasis on public safety in today's society, people pay more attention to disaster prevention. In addition to the disaster prevention design of buildings and the use of fire and earthquake resistant building materials, the evacuation and evacuation signs in buildings are also inaccessible. One of the missing equipment.

Fire regulations expressly stipulate that at the corners of indoor spaces, stairs, entrances and exits, security doors, escape doors or escape lines of buildings such as public places or homes, it is necessary to set up escape indicators, such as: direction indicators, floor indicators, Escape and evacuation indicators such as entrance and exit lights are used to guide personnel to escape directions and indicate exits in the event of fire or other accidents, so that they can quickly evacuate from the disaster site. However, today's escape indicators only provide a reminder function of lighting, not everyone knows the escape route and disaster situation, and displays the same status indication in normal and critical situations, making it difficult for people to discover the occurrence of a crisis. Furthermore, when a fire broke out, the visibility in the room was low, and it was impossible to clearly know the direction or location of the escape, and the smoke filled the air. Not only was it difficult to breathe, but even the eyes could not be opened, so people had to close their eyes to escape. In this case, the escape personnel have no way to clearly see the escape direction indicated by the "escape indicator light", and are often trapped inside because they can't escape in time. Furthermore, in large houses or shopping malls, due to the dense population of residents/personnel, the escaped residents/personnel will flock to one place according to the evacuation indicator, which is very likely to cause a stampede accident; at the same time, the situation at the fire scene is changing rapidly, sometimes There is a fire in the evacuation passage, so the evacuation instructions are likely to guide the personnel to a dangerous escape route. It can be seen that the current warning related equipment in the event of a fire has a limited effect.

The rescue personnel can receive the search and rescue notification information P2 from the cloud server 300 through their own portable mobile device 50 . The calculation and analysis results of the personnel location notification unit 322 can quickly understand the number of trapped persons on each floor: 1st floor: 3 trapped persons, 2nd floor: 1 trapped person, 3rd floor: 2 trapped persons, 4th floor: none Trapped persons, 5th floor: 3 trapped persons, 6th floor: 2 persons Trapped persons. In this way, the rescuers can immediately grasp the correct number of trapped persons and trapped positions on each floor before departure or when they arrive at the fire scene, which can be used as an important reference for the priority of rescue. It can be easily seen from Figure 5 that because The number of people trapped on the 1st and 5th floors is larger than that on other floors. Therefore, the 1st and 5th floors should be the first floors for rescue workers to replace the traditional carpet search and rescue method.
