The invention discloses a swimming pool lifesaving system based on a smart bracelet. The system comprises a hydrophone array, a smart bracelet, an indication system and a control computer, the hydrophone array is composed of a series of underwater microphones at fixed positions and corresponding calibration microphones, and a micro-controller, an ultrasonic loudspeaker and an oximeter are arrangedin the smart bracelet. The indication system comprises a holder and a light source system, the control computer combines the other three subsystems into an organic whole, a coordinate system is established for the swimming pool according to known microphone positions, an equation set can be listed by utilizing the propagation speed of sound waves in water according to the time difference of ultrasonic signals received by a plurality of microphones recorded by the computer, and the distances from the microphones to a sound source can be calculated. According to a triangular positioning principle, the position of the sound source in the swimming pool coordinate system can be accurately calculated, and after the coordinate is calculated, the computer is controlled to converge the light to the sound source, namely the position of a drowning person, so that the rescue is facilitated for nearby personnel.

    本发明基于智能手环的泳池救生系统及方法,包括水听器阵列、智能手环、指示系统和控制计算机,水听器阵列为一系列固定位置的水下麦克风和对应的校准麦克风组成,智能手环内部含有微控制器、超声波扬声器和血氧测量仪,示系统包括云台和光源系统,控制计算机把其他三个子系统结合成为一个有机整体,由已知的麦克风位置,对游泳池建立坐标系,再根据计算机记录下多个麦克风接收到超声波信号的时间差,利用水中声波的传播速度就可以列出方程组,计算出麦克风到声音源的距离。再根据三角定位原理,就可以准确计算出声源在游泳池坐标系中的位置,计算出坐标后,控制计算机将指示系统将光汇聚到声源处,也就是溺水者的位置,方便附近人员施救。
