【正文】 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。 本論文還介紹了處理數(shù)據(jù)的軟件方法。主控電路的單片機(jī)采用了 MSP430 系列中的 MSP430C1351；系統(tǒng)設(shè)置了液晶顯示模塊，能提供給用戶實(shí)時(shí)的心電波形和體溫；數(shù)據(jù)存儲(chǔ)功能可以存儲(chǔ)用戶的各項(xiàng)生理信息，以供醫(yī)護(hù)人員診斷做參考；系統(tǒng)終端可通過 COM 口和 USB 口與監(jiān)護(hù)中 心計(jì)算機(jī)進(jìn)行通信。此外，還有相應(yīng)的少量數(shù)據(jù)處理軟件等。GPRS 的遠(yuǎn)程醫(yī)療系統(tǒng)中數(shù)據(jù)采集終端的設(shè)計(jì)方法。該系統(tǒng)主要由四部分組成：體溫采集、心電采集、主控電路和藍(lán)牙通信模塊。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(jìn)行非線性補(bǔ)償；心電采集部分采用了金屬板電極作為傳感器，并對(duì)采集到的心電信號(hào)做放大和濾波等處理，并設(shè)計(jì)了數(shù)字濾波器對(duì)心電信號(hào)進(jìn)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(shí)時(shí)時(shí)鐘、數(shù)據(jù)存儲(chǔ)、液晶顯示、低電量報(bào)警和通信接口等。藍(lán)牙通信模塊用于采集終端與 GPRS 模塊之間數(shù)據(jù)通信。在體溫信號(hào)的處理中，介紹了線性插值法進(jìn)行線性補(bǔ)償；在心電信號(hào)的處理中，設(shè)計(jì)數(shù)字濾波器進(jìn)一步濾波并介紹了一種心電數(shù)據(jù)壓縮的方法。 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。 Data stored can store users’ physical information, and doctors can diagnose the disease。 E In ECG signal processing, it introduces the design of digital filter and a kind of ECG data pression method.
