Research On The Accurate Position And Guidance System About The Trapped In High-rise Building

With the social development and the improvement of people’s livingstandard,the advantages of high-rise building appear continuously, and promote theprocess of urbanization.High-rise building density is low, which is advanced to urbanlandscaping. small footprint,pipelines and other facilities can be concentrated roadlayout, effective conservation municipal resources;Development and application ofmodern advanced technology for the development of high-rise building to provide ascientific basis, so that continue to achieve new results in the construction sectorThe advantage of high-rise building is constently realized and accepted bypeople,while when we enjoy the convenience of high-rise building, the risk factor isbeing existence. Fires,earthquakes,terrorist attacks and other security threatsaccidents grim high-rise buildings.Therefore the problem of rescusing trapped inhigh-rise building is very important.Zigbee technology is a low-power,high-efficiency wireless senor networktechnology with high reliability, low cost,long standby time and so on.Zigbeetechnology is widely used in intelligent buildings,industrial automation,medicine andother fields.This text describes a positioning system based on Zigbee technology, the trappedaccurate position in the emergency situation can be achieved and timely guide in thehigh-rise building. This text mainly introduces the development of wireless sensornetworks, Zigbee technology included. This text mainly expounds the total designscheme of system, the design of reference node and blind node. Reference nodechooses CC2430chip and Blind node chooses CC2431chip.The system uses Zigbeetechnology, CAN bus technology, computer control technology, targeting algorithm,combined fire radio system and intelligent evacuation system to achieve athree-dimensional accurate positioning and evacuate the trapped in high-rise buildings.The system has the advantages of high positioning accuracy, good real-time,low-power, high reliability. And then the system effectively solve the problems of positioning allowed, search and rescue difficult, real-time and poor.
