一种无线断电报警装置的设计

Design of a Wireless Power-off Alarm Device

目的设计一种无线断电报警装置。方法采用HT66F489为主控芯片,通过比较器对市电的时时监测,当市电异常时,一方面报警装置上的蜂鸣器直接报警,以提示医务人员设备供电异常,另一方面以无线的形式将断电报警信息发送给医学工程科工作人员,以提示尽快采取相应措施。整个报警装置可以外接任何监测设备,也可以镶嵌内供电插座内部,使用自由度高。结果经过临床测试,设计的无线断电报警装置可以以外接的方式连接各种长时间连续工作的医疗设备,达到时时监测的目的。结论设计的无线断电报警装置非常适合各种医疗设备的断电监测,进一步提高临床服务质量。

Objective To design a wireless power-off alarm device.Methods HT66F489 was used as the main control chip,and the city electricity was monitored through the comparator.When the city power was abnormal,an alarm device on the buzzer alarmed directly to prompt the medical equipment power supply anomalies.On the other hand,the power failure alarm information was sent to the medical engineering department staff in the form of wireless,so as to prompt the corresponding measures as soon as possible.The whole alarm device could be externally connected with any monitoring device,and could also be embedded inside the power supply socket,with high degree of freedom.Results After the clinical test,the designed wireless power-off alarm device could connect all kinds of long time continuous medical equipment in a way of external connection,so as to achieve the purpose of monitoring at any time.Conclusion The designed wireless power-off alarm device is very suitable for power failure monitoring of various medical devices,and further improves the quality of clinical services.
