近年來，心律變異性（Heart rate variability，HRV），一直是相當熱門的研究，在諸多非侵入式量測的生理信號中，是最常使用的，也最具有參考價值，而無線感測網路Zigbee之技術相當成熟，其應用也相當多，從保全系統、醫療系統、自動化系統等等，其技術擁有低成本、低耗電可應用於長時間監控。 本論文主要目的，是將HRV訊號應用於Zigbee無線傳輸系統，使HRV與Zigbee做結合，改變目前測試方式，將有線系統轉換成無線系統，以克服環境上之限制，及探討Zigbee無線系統之無線傳輸距離與天線涵蓋範圍，進而分析無線HRV訊號。 In recent years, the Heart Rate Variability (HRV) has been a popularly studied subject. Among various non-invasive measurements of physiological signal, the HRV is an extensively utilized data to provide the most valuable physiological reference. The Zigbee technology is a rather mature technology it has the advantages of low cost, low power consumption and can be applied in long-time monitoring; it has many practical applications such as in the fields of security system, medication system and automation system. The task of this report is to apply HRV in the Zigbee-implemented wireless transmission system and to Integrate HRV and Zigbee together to change the current HRV transmission from the wired one into the wireless system. The characteristics of the wireless HRV signals will be investigated; it will study the possible transmission and coverage range of the integrated Zigbee-HRV wireless transmission system and try to remove the restriction of its transmission in the wired environment.
