碩士 === 國立臺北科技大學 === 電子工程系研究所 === 105 === Positioning technology has concerned and rapidly developed in recent years. Different from the Global Positioning System(GPS), Assisted Global Positioning System(AGPS) and other outdoor positioning system, etc. Although outdoor positioning technology has fully developed and widely used, as the end of positioning technology, however, the development of indoor positioning technology has relatively slow. And people spend more time indoor on work and life, thus the prospect of indoor positioning technology is also very broad. The indoor positioning technologys future will be more important with the rapid development of the Internet of Things, as technology improves every day, indoor positioning system will increasingly popularize, become indispensable in our life. ZigBee is applied for indoor positioning, because its transmission distance is 10~75 m, suitable for using more than three ZigBee network detection node to cover entire indoor space, ZigBee network can through 3 to 16 network detection node to enhance receiving signal to reach purpose of positioning, and meet environments the signal attenuation as moving object positioning. Presently, this technology is widely used in indoor factory workers positioning, can clearly show the location, and provide relevance information for use. Even can be used in factory workers security, e.g., when into the dangerous area, will send warning early. This paper presented using ZigBee network to locate positioning, ZigBee network through the technology of Received Signal Strength Indicator (RSSI). In the laboratory, use this technology Architecture to locate positioning, using four ZigBee network detection nodes to locate positioning, and present a way to improve the positioning.
