臺灣博碩士論文加值系統

本論文提出新穎的感測系統，主要量測人體手指姿態。透過建立感測數據資料庫與量測得到的感測數據進行感測演算，判讀出感測狀態。天線感測器在傳輸上不倚賴任何傳輸協定；加上天線結構單純、硬體成本相對較低；故可使用於大範圍監控。透過偶極天線作為感測器的基礎，分析其天線輻射場型、天線參數與彎曲角度的關係。天線為主動式天線，將兩種不同的振盪訊號連接混波器產生出多頻訊號，透過接收模組將接收之時域訊號轉為頻域訊號。取得6-8個頻域峰值作為特徵矩陣，並建立出特徵資料庫。辨識方式為將感測矩陣使用最小歐氏距離算出最小距離，可成功判讀出手指姿態與角度。本研發技術可應用於即時監視，把感測器智能化。此技術亦可延伸於距離量測、壓力、濕度與溫度等相關之無線感測。除醫療領域之外，無人駕駛車、無人機、智能工廠、智能居家等領域也將受惠於此新技術。

This paper proposes a novel sensing system, which mainly measures the posture of human fingers. The sensing calculation is performed by establishing a sensing data database and measuring the sensing data to determine the sensing state. The antenna sensor does not rely on any transmission protocol for transmission; in addition, the antenna structure is simple and the hardware cost is relatively low; therefore, it can be used for large-scale monitoring. The dipole antenna is used as the basis of the sensor to analyze the relationship between its antenna radiation pattern, antenna parameters and bending angle. The antenna is an active antenna. Two different oscillation signals are connected to the mixer to generate a multi-frequency signal, and the received time domain signal is converted into a frequency domain signal through the receiving module. Obtain 6-8 frequency domain peaks as the feature matrix, and build a feature database. The recognition method is to use the minimum Euclidean distance to calculate the minimum distance of the sensing matrix, which can successfully determine the finger posture and angle. This research and development technology can be applied to real-time monitoring, making the sensor intelligent. This technology can also be extended to wireless sensing related to distance measurement, pressure, humidity and temperature. In addition to the medical field, fields such as unmanned vehicles, drones, smart factories, and smart homes will also benefit from this new technology.
