Building fire intelligent rescue system and method based on ubiquitous network

Abstract

The invention discloses a building fire intelligent rescue system based on a ubiquitous network. The system comprises a fire monitoring network, a handheld terminal, a monitoring center computer and a fire fighting command terminal, wherein the fire monitoring network consists of a plurality of convergence sub-networks and is connected with the monitoring center computer through wireless convergence nodes of the convergence sub-networks and a 3rd generation (3G) network; each convergence sub-network is a wireless sensor network which is provided with a main-chain-type topology structure consisting of wireless sensor nodes, namely fire monitoring nodes; and the handheld terminal comprises a query handheld terminal and a rescue handheld terminal, reads the label data of radio frequency identification (RFID) data of neighboring fire monitoring nodes of the handheld terminal by an internal RFID card reader and an RFID reading link which are arranged in the hand-held terminal, and exchanges data with the monitoring center computer through the 3G network. The system has the advantages of convenience in arrangement and high real-time capability; and the system can effectively assist firetrapped personnel in escaping and fire rescue personnel in making a rescue scheme; and intelligent guide is provided for the fire trapped personnel and the fire rescue personnel under the emergency condition of fire, and lives and property can be effectively rescued.

Description

technical field [0001] The present invention relates to a fire intelligent rescue method and system in a high-rise building or complex terrain environment, in particular to a building fire intelligent rescue system and method based on a ubiquitous network. Background technique [0002] Among many disasters, fire has become one of the most frequent, destructive and most influential disasters in our country. In my country's fire statistics, building fires account for more than 80%. With the rapid development of economy and urban construction, high-rise buildings have become one of the symbols of urban modernization, followed by a great increase in fire hazards, and high-rise building fires are also emerging one after another. The number of high-rise building fires and the losses they cause are all There is an increasing trend year by year. After a high-rise building fire occurs, due to the characteristics of dense population, difficulty in evacuation and rescue, block fire d...

Although there were no casualties, the residents suffered heavy property losses; A fire broke out in a high-rise building, causing 42 injuries and an economic loss of about 6 million yuan; on November 5, 2010, a major fire broke out in a commercial building in Chuanying District, Jilin City, Jilin Province, resulting in 19 deaths and 24 injuries; On the 15th, a huge fire broke out in a high-rise residential building in Jing'an District, Shanghai, killing 53 people, injuring 70 people, and property losses of nearly 500 million yuan

WSN and RFID technology have the advantages of short distance, high speed, low cost, and convenient network construction. In the past, there were precedents for applying these two technologies at the same time in the fire rescue system, but the communication distance and service quality of these two technologies are limited. In the complex building environment with long-distance communication, the fire rescue scheme using WSN and RFID technology cannot work effectively or even paralyze the system
