| 摘要: | 密閉或高風險作業環境，如下水道、工業管線與地下設施，常伴隨高溫、有毒氣體、氧氣不足與氣體積聚等危險因子，對作業人員安全構成重大威脅。為提升現場作業安全與即時監控能力，本研究旨在開發一款具備生理與環境多參數監測功能之穿戴式系統，並可支援遠端即時資料傳輸與視覺化監控。
基於上述的環境風險，本論文研究與開發具遠端監控功能之即時生命跡象與氣體監測系統。本系統由兩個主要子系統組成：穿戴式裝置與地面監控終端。穿戴式裝置整合心率、血氧濃度與環境中有毒氣體濃度之感測模組，並透過低功耗無線通訊模組傳輸資料至地面主機，後者再透過網路將資訊上傳至伺服器，使近端與遠端皆可透過人機介面同步掌握人員生命跡象與作業環境狀況。整體系統採用可充電式鋰電池供電，具備可攜性與現場部署彈性。
實驗結果顯示，本系統可穩定量測並即時反映氣體濃度變化與生命跡象變化，所獲數據與標準儀器高度一致，且資料傳輸過程具高穩定性與準確性。此系統有助於強化高風險場域中人員安全監控機制，未來將進一步優化耗能表現並朝向更小型化之設計以提升實用性與攜帶便利性。
;Confined or high-risk working environments, such as sewers, industrial pipelines, and underground facilities, are often associated with hazardous conditions, including high temperatures, toxic gases, oxygen deficiency, and gas accumulation, all of which pose significant threats to worker safety. To enhance on-site safety and enable real-time monitoring, this study aims to develop a wearable system capable of multi-parameter physiological and environmental sensing, with support for remote data transmission and visualization.
To address environmental hazards, this thesis details the development of a real-time vital signs and gas monitoring system with remote capabilities. The system comprises a wearable device, which measures heart rate, blood oxygen saturation, and toxic gas levels, and a ground-based monitoring terminal. Data is wirelessly transmitted to a local base station, then forwarded to a server via the Internet. A web-based GUI allows local and remote access to real-time data, providing continuous awareness of personnel′s physiological status and environmental conditions. A rechargeable lithium battery powers the entire portable system for flexible field deployment.
Experimental results demonstrate that the system measures and responds to fluctuations in gas concentration and vital signs, producing data consistent with standard instruments. Stable and accurate data transmission ensures timely and reliable physiological and environmental information during field operations. This promising solution enhances safety monitoring in high-risk environments. Future development will focus on optimizing power consumption and miniaturization to improve usability and portability. |
