Beijing high-rise fire problem breaking vote by 10 million people trapped chips closed position - high-rise building fires, fire and rescue techniques
A rescue "global high-rise building fires key technology research and demonstration" projects of great 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 rescue tall building and the difficulties faced by fire, fire fighting difficult and hard on three main aspects of the command.
Crack rescue difficult
Chip lock trapped in one place
"Tut!" Building Science, Tsinghua University, creating Access ago, a staff member of the forefoot credit card door, the three-level platforms at the same time command shows its route and location of the simulation run. Mystery at the door of Cary in his hands. Once inside the building fire Fireman can be created with the introduction of a chip card, remote locking trapped in the specific location, specific to start the rescue.
In Olympics tickets, RFID smart chips in their abilities fire in high rise building rescue and research will play a new role as a firefighter "Electronic Eye." In recent high-rise building on fire when firefighters outside the building is often difficult to determine the number of people inside the building, location and physical condition. In the future, "hiding" at the door of Cary staff will be issued smart chip radio frequency signal. As a platform fire control unit can clearly see the position of all holders cards and escape routes.
"When the representative of the red dot on the screen fixed, and that this person is likely to fall, injury or asphyxia fainted when the anti-fire special relief against them. "SAFETY Tsinghua University Dr. Zhang Hui central side ahead in the presentation introduction computer, of course, the radio frequency RFID technology staff members can determine the location and movement of non-house staff and low staff but also based on the buildings of video equipment.
Fight hard to break:
Super high pressure water pump direct 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 point of delivery of fire water is to make the most headaches for firefighters problem. General fire truck ladder to only 30 meters, while the fire pump is bearing pressure limited, usually only on the water at 100 meters high. If fire occurs in a higher position, firefighters can expect only the breath of fire.
Previously, the Science and technology experts from Beijing Commission have sought to use "airship," spraying fire extinguishing powder in height, but the end result of air traffic control, the clear line of sight and the smoke may have other reasons for leaving the second risk. Currently, the commitment to this important special engineering experts are studying a double piston pump high pressure water technology, if successful, may trigger the 2400 liters of water that reaches over 300 meters high.
"The light well enough," Director of Beijing Municipal Commission of Science and Technology for the Department Social Development, Chang with stress, water high pressure also need some fire, are being developed in the hydraulic system very "symptomatic" pressure of the continuous system by the way, is expected to exert increasing pressure from the nozzle, a range of 15 meters. "Two-track approach to really capture aerial firefighting problems. "
Hard to break the command:
Mobile devices to track firefighters and fire
Adding to the difficult rescue, the fire difficult, high-rise building, no doubt, a symbol of fire is a major problem. More buildings high-rise in the center of the city, the external environment is complex, fire trucks stuck in traffic is nothing new anxious. Beijing Municipal Commission of Science and Technology for research and development of mobile command system can be installed in the fire in the GPS satellite positioning and time sensor to send real fire command center staff around the building fire, road and traffic conditions to help the deployment of vehicles firefighters, and rescue to be developed.
"Into the fire building all firefighters carry a RFID radio frequency receiver," presented by Dr. Zhang Hui This small device, the command center to track not only the fire together, but also the real-time control of their heart, temperature indicators, such as vital signs, once fatigue, substitutions will be immediately instructed.
