基于心率检测的儿童溺水呼救报警系统设计

Design of Children Drowning Alarm System Based on Heart Rate Detection

儿童自我保护意识差、危险辨识能力弱,尤其是在游泳等户外运动时因兴奋而导致忘我。暑期儿童溺水事件频发,给溺水儿童家庭带来了无尽的痛苦。设计并制作了一款基于心率检测的儿童溺水呼救报警系统,该系统可以实时监测儿童的心率,当儿童在游泳时心率数值出现异常,系统将及时发出溺水呼救报警的信号。系统以STC89C52单片机为主控芯片,用ST188光电传感器采集儿童心率信号,采用滤波整形电路对采集到的心率信号进行处理并送入单片机,同时将实时的心率数据显示在LCD1602液晶屏幕上,实现了溺水第一时间发出报警功能。

Children have poor self-protection awareness and weak risk identification ability,especially in outdoor sports such as swimming leading to ecstasy.The frequent drowning incidents in summer bring endless pain to the families of drowning children.A drowning alarm system for children based on heart rate detection is designed and made,which can monitor the heart rate of children in real time,and send out the drowning alarm signal in time.The system uses STC89C52 as the main control chip,uses ST188 photoelectric sensor to collect the heart rate signal of children,and uses the filtering and shaping circuit to process the signal then sends it to the single-chip computer.The real-time heart rate data is displayed on the LCD1602 screen,and triggers the alarm.
