碩士 === 樹德科技大學 === 電腦與通訊系碩士班 === 107 === In this paper, we will analyze the measured data of Bluetooth RSSI (Received Signal Strength Indication) and apply it to the umbrella to design a smart technology umbrella that can automatically detect the distance from the user. In order to achieve the objectives, we first study the distance detection of wireless signals, RSSI is inversely proportional to the distance, thereby estimating the distance between the transmitting end and the receiving end., thereby estimating the distance between the transmitting end and the receiving end. In practice, we conducted multiple measurements and experiments to establish the relative relationship between the RSSI and the actual distance. The results of the study were applied to the anti-theft anti-lost warning of the umbrella. The mobile APP program will convert the RSSI into a distance. When the distance is greater than the value set by the user, the mobile phone and the umbrella will simultaneously emit a warning sound and a flashing light.
