摘要
设计一种可对温度信号、心电信号实时监测的无线人体生理体征监测系统,系统充分利用MSP430单片机丰富的片内资源,降低了心电检测前置处理电路的功耗和体积,测量精度高,能有效抑制工频干扰和基线漂移,具有导联脱落自动探测,抗高频电刀干扰,抗心脏起搏器干扰等功能。带宽0.05—200Hz。系统采用分级分布式无线测控通信方式,中心监测站通过无线收发模块,可与多个便携式体征监测仪进行通讯,不需设置传输导线。在一定范围内,患者可移动、可隔离,系统也可移动、组网灵活方便。
To develop a wireless monitor system of moveable physiological signals .The system can monitor temperature signal and electrocardiogram （ECG） signal by wireless real-time. The interference of 50Hz and base line drift can be availably restrained. The functions include the automatic detect to the electrode shed off, restraint the high frequency interference such as the electric quire and the cardiac pacemaker. Bandwidth is 0.05--200Hz.The volume and the power waste are reduced, the accuracy of measuring is increased by using the rich inside resource of MSP430 single chip processor. The wireless control is classification and distributing mode. The center monitor communication with many detecting apparatus of physiology signal by wireless module without transmission lead. The detected person may move and be insulated in the area, when measuring.The system may be moved too. The buildup of the system network is agility. The install is easy.
