Research on the accurate positioning system based on Zigbee for the trapped people in high-rise buildings

An accurate positioning and guidance system based on Zigbee was designed for the trapped people in high-rise buildings. In the system, Zigbee technology, CAN(Controller Area Network) bus technology, computer control technology and targeting position algorithm, in combination with the fire radio system and intelligent evacuation guidance system, were used to achieve a three-dimensional accurate position and evacuation guidance for the trapped people in high-rise buildings. With the advantages of high positioning accuracy, good real-time, low-power and high reliability, this system can effectively solve the problems of inaccurate positioning, difficult search and rescue, poor real-time existing in the fire search and rescue work.
