摘　　要：设计了一种输液瓶液位监测报警系统。该系统以光的折射原理为基础,将光电开关与透镜结合到一起,当输液瓶中的液位到达警戒位置时,光电开关输出的微弱信号经放大器放大和比较器滤除干扰信号后输出高电平,触发报警系统发出声光报警,以此来提醒医护人员进行相应处理。系统灵敏度高,成本低,具有很好的应用价值。This paper designs a kind of monitoring and alarm system of infusion bottle liquid level. This system is based on the principle of light refraction and combines photoelectric switch with optical lens, when the liquid level in the infusion bottle reaches to the alert position, the weak signal exported by the photoelectric switch is enlarged through enlarger and filtered out interfering signals through comparer and exports the high electrical level, then it trigger the alarm system to send out audible alarm and in order to remind the medi-cal staff to deal with the matter. The system has high sensitivity, low cost and good application value.
