摘要


本文的目的是以嵌入式微控制器開發一套簡易型、低價位、多功能生理訊號量測模組,可以針對個人進行連續的健康監控。目前階段已完成的量測生理訊號包括心電圖、肌力、體溫和血壓脈搏等。本系統採用ATMega 8515嵌入式微控制器作為核心晶片平台,一方面監測生理訊號並將測量結果即時顯示在320×240的繪圖型液晶顯示器上,另一方面則透過UART介面即時傳送量測資料至個人電腦上,以便進行各種不同的資料處理(包括資料壓縮、小波基底轉換或者頻譜分析等)。期望未來這套系統具有自行診斷的功能,尤其能夠結合中醫的脈診,對於人體心、肝、脾、肺、腎的氣血強弱作有效的評估。

The objective of this paper is to develop a small type, low cost, multi-function physiological signal measurement module integrated in an embedded micro-controller for monitoring the index of health. Up to now, the different kinds of measurement signals including ECG, muscle strength, body temperature, blood pressure and pulses are merged into our system. The ATMega8515 family of 8-bit RISC provides the ultimate solution to measure the physiological signals displayed in 320×240 graphic mode LCD, as well as transmit to PC via standard industrial interface RS232 for data processing. Self-diagnosis is expected in future works, in particular, Chinese medicine diagnosis by feeling the pulse can be combined to evaluate the strong or weak for the heart, liver, spleen, lung, kidney of human.
