METHOD OF DETECTING POSITION OF ZIGBEE TAG AND SYSTEM THEREFOR

摘要

PURPOSE: A method of detecting a position of a ZigBee tag and a system therefor is provided to calculate position information accurately even though a wireless propagation environment such as a mobile phone is changed. CONSTITUTION: Plural ZigBee fixing nodes(1201-120n) deliver radio signals, and plural ZigBee mobile nodes(1101-110n) detects the strength of a receiving signal for each wireless signal. Based on the strength of the receiving signal from the ZigBee fixing nodes, the ZigBee mobile nodes calculate the proportion values of the radio signal strength of the rest ZigBee fixing nodes. The proportion information is transmitted to the outside, and a server(140) detect the positions that correspond to the proportion values of the plural receiving signal strengths.
