| 摘 要： | 心源性病人或体弱老人在运动或沐浴时常常会诱发心肌梗塞,如不及时发现救护即会导致猝死发生.多普勒监护仪就是针对此类情况研制的一种报警装置.监视仪基于雷达技术、微波技术、电子技术等,由外部天线向空间发射微波,形成一个立体空间的微波监视网,当网内人或物在一定时间内无活动时发出求救信号提醒他人注意.本文详细介绍了监护仪的设计思路,确定了主要电路结构及其参数,制作了原理样机,通过实验验证了其功能和可靠性并对出现的技术问题做了处理.所研制的监护仪监护范围和时间可调,成本低、体积小、生产工艺简单,使用方便灵活,具有较高的实用价值和推广价值.

| Abstract: | When patient who has heart disease or low old person is exercising or washing,miocardial infarction always occurs,and if not get rescue unexpected death will happen.Based on Doppler's effect,a novel instrument has been developed,which sends out warning signal when inspects somebody not moving in a period of time.Techniques about radar,microwave and electronics are applied in development.Main circuits and parameters have been designed and analyzed in detail.The feasibility of instrument has been verified by experiment.The instrument's merits are adjustability of time and range,low cost,small volume,which is worth using. |
