position - high-rise building fires, fire and rescue techniques
A "comprehensive rescue high-rise building fire key technology research and demonstration" projects of major importance, has been officially launched by experts argued, Beijing, Beijing Municipal Science and Technology Commission will invest 10 million yuan, plans to use three years to resolve the current high-rise building Fire Difficulties facing rescue, fire fighting difficult and hard on three major issues the command.
Crack rescue difficult:
Chip Lock Be trapped in one location
"Toot!" Building Science, Tsinghua University, building access ago, a staff member forefoot Credit card Door, three-tier computer command platforms at once shows his route and location of the simulation run. Mystery on the door of Cary in his hands. Once inside the building fire Fireman Can be created by implanting a chip card, remote locking trapped in the concrete location, targeted to launch the rescue.
In Olympics Tickets, RFID smart chips in their skills in high-rise building fire and rescue research will play a new role as fireman " Electronic Eye . "Over the past high-rise building on fire when firefighters outside the building is often difficult to determine the number of persons inside the building, location and physical condition. In the future," hiding "in the staff door Cary will be issued smart chip radio frequency signal. As receiver Fire command platform can clearly see the position of all cardholders and escape routes.
"When the representative of the red dot on the screen fixed, and that this person is likely to fall, injury or suffocation fainted, when firemen's special relief measures taken against them." SAFETY Tsinghua University Dr. Zhang Hui center side edge introduction in the computer presentation, of course, RFID radio frequency technology to staff members can determine the location and movement of non-house staff and personnel casualties, but also rely on the buildings of the video equipment.
Fighting hard to break:
Super High-pressure pump Direct water to 300 meters
For high-rise buildings that once appeared in the last 100 meters of the high degree of fire, how to successfully fire the fire water delivery point is to make the most headache problem firemen. General fire ladder truck to only 30 meters, while the fire pump bearing pressure is limited, usually only about the water to 100 meters high. If fire occurs in a higher position, firefighters can only hope the fire sigh.
Earlier, the Beijing Science and Technology Commission experts have tried to use "airship," spraying fire extinguishing powder in the high altitude, but the end result of air control, clear line of sight and the smoke may have other reasons to give up the second risk. At present, the commitment to this important special engineering experts are studying a dual piston high pressure pump water technology, if successful, can fire off the 2400 liters of water delivered to more than 300 meters high.
"Light highly enough," Director of Beijing Municipal Science and Technology Commission for Social Development Department, Chang with stress, the water at high altitudes also need a certain pressure to fire, being developed in the hydraulic power system very "symptomatic" of the system continuous pressure by the way, is expected to exert increasing pressure nozzle, a range of 15 meters. "Two-pronged approach to truly capture aerial fire-fighting problems."
Difficult to break the command:
Wireless devices to track firefighters and fire
Addition to the rescue difficult, the fire difficult, the high-rise building fire command undoubtedly is a major problem. More high-rise buildings in the city center, the external environment is complex, fire engines stuck in traffic anxious is nothing new. Beijing Municipal Science and Technology Commission for this research and development of mobile command system can be installed in the fire on the GPS satellite positioning devices and sensors, real-time to send the fire command center staff around the fire building, road and traffic conditions to assist the deployment of fire appliances, and develop rescue.
"Into the fire every building firemen carry a RFID radio frequency receiver," Dr. Zhang Hui introduced by this small device, the command center to track not only the whole fire, but also real-time control of their heart, temperature indicators such as vital signs, Once it was fatigue, substitutions will be immediately issued instructions.
