基於Android平台實現即時Bluetooth與ANT心電訊號監測並應用於遠端病症分析
Design and Implementation of an Android-based Portable Real-Time ECG Monitoring with Heart Disorder Detection On-line Service
摘要
本論文在Android平台上實現藉由Bluetooth或ANT傳輸協定達到心電圖監測與紀錄系統，並應用於遠端專家心臟疾病分析系統，本論文分兩部分，心電圖監測與紀錄系統、遠端資料庫搭配心臟疾病分析系統，在前端心電訊號的擷取與處理部分，使用現有的ECG放大電路，透過MSP430做心電訊號的取樣與類比/數位轉換，再將訊號透過Bluetooth模組或ANT模組傳至Android手機端。在Android手機端，本論文實作AwinECGWave軟體整合Bluetooth和ANT通訊協定，使得Android手機能選擇上述兩種無線傳輸協定之一來接收ECG，能即時繪製使用者ECG波形，並即時的計算使用者當前心跳速率(Heart Rate)顯示於螢幕上方。當使用者停止ECG量測，可將該筆量測訊號儲存在SD卡，再透過手機軟體紀錄功能檢視各筆儲存在SD卡上的ECG，或選取紀錄中某筆ECG透過網路上傳，並應用遠端資料庫MYSQL儲存與後端電腦軟體運算分析該筆資料，該筆資料會依照該Android手機使用者分類儲存在資料庫中，透過遠端架設的電腦軟體心臟疾病分析系統分析，而心臟疾病分析系統能做到QRS各波的偵測、各段R-R Interval、Heart Rate、HRV、與辨識出九種心臟病徵，並將分析完數據儲存回資料庫中。搭配Android手機隨時搜尋有無分析完數據並下載回至手機端觀看，為方便也提供該專屬系統網頁觀看分析結果，讓使用者或醫療團隊可透過電腦、手機、平板3C裝置上網觀看歷史分析數據。

The main purpose of this paper is to design and implement a portable telecare system in cardiology. The designed system is an Android-based telecare system with two types of RF, the Bluetooth and ANT protocols. This paper focuses on two parts: (1) the Front-end ECG sisgnal acquisition system and (2) the remote database with an expert system that can detect the heat disorders. We use the existing ECG amplifier circuit board to acquire and process the ECG signal. In addition, a MSP430-based embedded system is used to perform the sampling and A/D signal conversion. After ADC processing, the ECG signals are transmits through Bluetooth module or ANT module to the Android mobile PDA to relay the ECG signals to the remote database. The expert system on the server can perform useful algorithm to identify the heart disorder patterns.In particular, this paper designs and implements the "AwinECGWave" software for the Android device, which enables the Android phone to receive the ECG signal and display them in real time. When user stops measuring the ECG signal, the ECG signal can be stored in SD card and uploaded to the MySQL-based database for different phone users. The expert system can detect the QRS complex , R-R Interval, Heart Rate, HRV, and distinguish other hear disorder patterns. As a result, the user and the medical team can check the analyzed data anytime on the mobile devices or on the web site. The proposed portable telecare system can provide instaneous heart information to users.
