摘要
本研究之目的在探討嵌入式生理訊號量測、無線傳輸之資料品質與數量的關係，此系統以MSP430F149為核心，擷取由心電圖類比訊號板所產生的心電圖(ECG)，心電圖訊號之取樣率為200Hz，並利用量測系統上之TFT LCD即時顯示心電圖訊號。心電圖訊號經過MSP430F149類比數位轉換後，可經由ZigBee無線傳輸系統，直接將量測到的心電圖訊號即時傳送到接收端，在接收端經由USB直接在Borland C++ Builder所建立之使用者介面即時顯示、儲存收到的訊號，此使用者介面可將已經儲存於電腦中的訊號讀取出來並加以顯示，且在使用者介面上顯示接收資料的總時間與接收到的總資料量。本研究以四種量測方式，包含了第一組為發送端與接收端均在室內，相隔距離為6公尺。第二組為發送端在室內，接收端在室外，相隔距離為13公尺。第三組為發送端在室內，接收端在室外，並在兩者之間增加一個節點，發送端與節點距離為18公尺，節點與接收端距離為22公尺。第四組為發送端在室內，接收端在室外，並在兩者之間增加兩個節點，發送端與節點一距離為11公尺，節點一與節點二距離為14公尺，節點二與接收端距離為20公尺。以此四種方式來探討在不同距離與空間與ZigBee節點數量的傳輸量，當節點每一百平方公尺放置0.84個時，只有55.58%的資料傳輸量，當節點每一百平方公尺放置1.07個時，資料傳輸量增加至98.05%，因此本研究具體評估在一定的空間內，ZigBee節點數量的多寡對於生理訊號資料傳輸量之通透性有著明顯的關係。

The objective of the study was to discuss the relationship between embedded measurement of bio-signal and the quality and accuracy of wireless transmitted data. The system was integrated using MSP430F149 to acquire the signals of ECG. The sampling rate of ECG was 200 Hz. The signal was real-time displayed on the TFT LCD of the device. After analog to digital conversion by MSP430F149, the signals could be transmitted real time to the receiving point through the ZigBee wireless transmission system. With user interface created by Boarland C++ Builder at the receiving point, the received signal could be displayed and saved through USB. The user interface could read and display signals stored in the computer and also show the total time and the total amount of data received. This study discussed the amount that transmitted under the conditions of different distances, different space, and the different densities of ZigBee router by using four methods of measurement. The transmitted rate of data was 55.58% when the density of ZigBee router was 0.84 per 100 square meter. And the rate increased to 98.05% when the density was 1.07 per 100 square meter. Therefore, the study concluded that the quantity of ZigBee routers was positively correlated to the penetrability of bio-signal data transmission within a fixed space.
