第58届Intel ISEF中国参赛项目：泳池溺水报警器

学科：工程学

    溺水淹亡是3-14岁儿童非正常死亡的头号杀手，由此我们研制了“泳池溺水报警器”。
    该报警器采用了基于2.4G的无线网络通信技术、光电传感技术和计算机技术，可靠地实现了入水探测、信息传输和数据处理。报警器由溺水探测、手持报警和计算机数据处理装置三部分组成。正常情况下，溺水探测装置定时发射信号给手持报警装置和计算机。当游泳者的头部浸入水中时，溺水探测装置不发射信号，溺水探测、手持报警装置和计算机计时程序启动，若达到规定的计时门限后游泳者还未出水，程序判断游泳者溺水。此时，溺水探测装置发光闪烁，显示溺水者位置，手持报警装置和计算机声、光报警，以便救生员对溺水者施救。
    通过组网的方式，可用于海滨浴场或更广泛场合的报警。

Drowning is a top one killer of the unnatural death of children between 3 and 14 years old. Therefore, we develop an “Alarm System for Drowning in Swimming Pools”.

Adopting technology of wireless network communication in 2.4G, photoelectrical sensors and computer technology, this alarm system is reliable in detecting underneath water, information conveyance and data treatment. It consists of a drowning detector, an alarm handset and a computer data processor. Normally, the drowning detector sends signals to the alarm handset and computer at a fixed time. When a swimmer immerses his head in the water, the detector will not send signals, at the same time, the drowning detector, alarming handset and computer timing process start to operate. If the swimmer is still in the water beyond a specified timing threshold, the process estimates the swimmer is drowning. Then the detector emits radiance, indicating the location of the swimmer; the alarming handset and computer give light and sound for lifeguards to take measures to save drowned persons.

With a net-combining mode, it can be used for alarming in coastal bathing place or wider areas.
