無線生醫檢測平台之嵌入式行動裝置實現

Abstract

本論文以國立台灣大學的無線生醫奈米生醫檢測系統為發展中心，其中包括了三個部分植入式的體內感測器、無線生醫監控裝置和遠端健康監控伺服中心，本文中實現了以嵌入式ARM9模組為核心來設計周邊電路建構出一個無線生醫監控裝置的構想，裝置上架設Windows CE為作業系統，並且在無線生醫監控裝置上建構一初步訊號檢測系統，然後在健康監控伺服中心做更進一步的訊號診斷分析，並以心電圖來做為我們檢測的訊號的依據，其中訊號分析主要以頻譜估測和模糊群聚分析來作為生醫訊號檢測判斷的理論基礎。

This thesis develops a mobile transceiver for the NTU Wireless Health Advanced Monitoring Bio-Diagnosis System (WHAM-BioS). The system embeds one or more body-sensors into patient bodies and uses the mobile transceiver as a relay station to gather the bio-medical information and to relay the information up to the internet. The previous researches have developed the necessary fundamental technologies. This thesis realizes the technology into a small 7cm x 5.5cm device. The device is Win-CE based and runs on battery power for mobility. It is not only capable of relaying the data but can also perform preliminary biomedical signal analysis. This thesis demonstrated the embedded function on the device for preliminary ECG analysis. We use frequency spectrum templates as the basis for comparison and perform autoregressive model identification on the signals. Analysis results show that our device achieves conservative judgments which are necessary for safety operation.
