碩士 === 國立虎尾科技大學 === 航空與電子科技研究所 === 101 === In recent decades, technology has developed rapidly and the usage of high-tech building is also growing. Due to the structures, Global Positioning System (GPS) cannot receive signal transmission in the indoor space properly. Therefore, GPS positioning is ineffective in the indoor space. The study aims to implement an indoor positioning system which based on ZigBee wireless network. The researchers placed the reference node in the indoor space. Reference node send signals to the positioning node by ZigBee wireless signal transmission. Therefore, the researchers can calculate the distance between the reference nodes and the positioning nodes by received signal strength values. After calculating the distance of positioning node between the reference nodes and positioning node, the researchers can analyze the data and figure out the positions by Triangle Math. The current positions display on computer. With data and analysis of static and dynamic experiment, the researchers can find out the error of positioning and come out with the corrections. Indoor Positioning System with ZigBee wireless network improved the drawbacks of GPS by designing wireless, intelligent, humanization and low cost. It increases the accuracy of Positioning in buildings.
