【摘要】 研究了基于嵌入式计算机的多参数监护仪的设计原理与实现,该系统由多参数信号采集模块、嵌入式计算机系统和GPRS模块构成。介绍了嵌入式计算机系统的硬件和软件组成部分以及应用程序的交叉编译过程,并在此基础上实现了基于Qtopia的应用监护程序。该监护仪以嵌入式计算机为载体,以多参数信号采集模块采集到的血氧、心电、呼吸、血压、体温等人体生物医电方面的信号为基础,实现了基于无线GPRS的多参数实时在线监护。更多还原

【Abstract】 A multi-parameter monitoring instrument based on embedded system is presented. It consists of multi-parameter signal collecting module, embedded computer and GPRS module. Hardware, software and cross compiling of the embedded system are introduced, and the monitoring software based on Qtopia is also developed. The instrument is based on the vital bio-signal by multi -parameter signal collecting module, such as oxygenation of the blood, cardiograph, respiration, blood pressure and temperature, using embedded computer as baseplate. The system can monitor multi-parameter through wireless GPRS.更多还原
