【正文】 GPRS 的遠程醫療系統中數據采集終端的設計方法。該系統主要由四部分組成：體溫采集、心電采集、主控電路和藍牙通信模塊。此外，還有相應的少量數據處理軟件等。體溫采集部分采 用 NTC 型熱敏電阻作為傳感器，并在硬件和軟件方面進行非線性補償；心電采集部分采用了金屬板電極作為傳感器，并對采集到的心電信號做放大和濾波等處理，并設計了數字濾波器對心電信號進一步濾波，從而得到了高可靠性的心電波形；主控電路主要包括實時時鐘、數據存儲、液晶顯示、低電量報警和通信接口等。主控電路的單片機采用了 MSP430 系列中的 MSP430C1351；系統設置了液晶顯示模塊，能提供給用戶實時的心電波形和體溫；數據存儲功能可以存儲用戶的各項生理信息，以供醫護人員診斷做參考；系統終端可通過 COM 口和 USB 口與監護中 心計算機進行通信。藍牙通信模塊用于采集終端與 GPRS 模塊之間數據通信。 本論文還介紹了處理數據的軟件方法。在體溫信號的處理中，介紹了線性插值法進行線性補償；在心電信號的處理中，設計數字濾波器進一步濾波并介紹了一種心電數據壓縮的方法。 關鍵詞 ：遠程移動醫療 體溫采集 心電采集 山東科技大學學士學位論文 摘要 ABSTRACT In this paper， a method of the design of Data Sampling Terminal based on GPRS is introduced. The system consists of four main parts: temperature collecting, ECG collecting, the main control circuit, and Bluetooth munication module. Another, it also consists of data processing software. Temperature collecting uses NTC thermistor as sensor, the signal is nonlinear pensation in hardware and software。 ECG collecting uses metal plate electrode as sensors and the collected ECG is amplified and filtered, then it is filtered by digital filters. We will get the high reliability of ECG waveform. The main control circuit includes realtime clock, data storage, LCD display, lowpower alarm and munication interface, etc. The main control circuit uses SCM MSP430C1351 as core。 the design is also equipped with LCD module, and it can offer customers realtime ECG waveform and temperature。 Data stored can store users’ physical information, and doctors can diagnose the disease。 the system can municate with the puters in the monitor center by the COM port and USB port. Bluetooth munication module is used in the munications between Acquisition terminal and GPRS module. This paper also introduces the software method of data processing. In temperature signal processing, it introduces the method of linear interpolation。 E In ECG signal processing, it introduces the design of digital filter and a kind of ECG data pression method.
