摘要Abstract: 本研究提出了一套無線生理訊號傳輸系統,包含了微型無線生理訊號量測貼片、接收端與電腦觀測端,使用者可將貼片貼於胸前的第一導程位置量測心電訊號,並將此訊號送進TI公司研發的射頻晶片CC2430。此晶片內含了8051核心、類比數位轉換器、計時器與發送射頻訊號等功能,因此我們可利用C語言撰寫其韌體,將心電訊號轉為數位訊號並儲存於晶片的記憶體中,於一定時間之後執行無線發送的指令,並透過貼片上一自行設計之CPW型式的倒F天線,將射頻訊號於此轉換為電磁波發送至遠端接收器,接收器收到訊號之後會將訊號送至電腦端,使用者可透過LabView軟體設計的人機介面觀測心電圖。

A wireless micro biomedical signal transmission system has been designed and implemented in the thesis. This system is including a wireless micro biomedical signal measuring patch, receiver and a observing station. Users can affix this patch on their chest, and the ECG biomedical signal is sensed and processed by the ECG electrode sensor and its circuit respectively. Then send these signals into a chipset called CC2430 which integrates wireless front end module, analog to digital converter and a 8051 microcontroller. We can write firmware by C language to transform ECG biomedical signal to digital signal and then transmit by ZigBee wireless protocol to the ZigBee access node. And a CPW type Invert F Antenna is designed on the patch’s border, too. Finally, the ECG signal received by the remote node is plotted and shown on computer screen with the LabVIEW software system.
