Embodiment 1

[0038] An intelligent drowning monitoring alarm is an intelligent drowning alarm device worn on the swimmer's wrist, also known as an intelligent lifesaving watch. The intelligent drowning monitoring alarm is equipped with a sensor and a control chip for sensing water pressure and water depth. The intelligent drowning monitoring alarm is also equipped with an electroacoustic transducer that emits a sound wave signal. The control chip is analyzed according to the data collected by the sensor. Processing, the electrical signal is converted into an acoustic signal through a transducer, and when a swimmer is drowning, the electroacoustic transducer automatically sends out a sound wave signal for help;

[0039] The water pressure detection range of the sensor for sensing water pressure in the intelligent drowning monitoring alarm is 0-0.1 MPa, the detection error is ≤ 100 Pa, the maximum underwater depth that can be detected is 10 meters, and the detection depth error is ≤ 0.02 mete...

Embodiment 2

[0053] like figure 1 , a swimming pool drowning lifesaving system installed in a public standard swimming pool of 25 meters x 50 meters, including the intelligent drowning monitoring alarm (smart lifesaving watch) worn on the swimmer's wrist as described in the first embodiment 10, set in Three acoustic-electric transducers 20 in three corners of the swimming pool, and a computer data processing device 30 arranged in the rescue room; The signal receiving and converting device receives the acoustic signal from the intelligent drowning monitoring alarm underwater, converts it into an electrical signal, and transmits it to the data processing device through a wired data cable. The data processing device processes the received signal and accurately locates the drowning person at The location in the water, recording and displaying the underwater movement track of the drowning person.

[0054] The underwater acoustic signal receiving and converting device includes an acoustic-elect...

Embodiment 3

[0059] like figure 2 , this embodiment is a swimming pool drowning rescue system according to Embodiment 1, which uses radio communication technology to send signals from the acoustic-electric transducer to the data processing device.

[0060] The upper end of the acoustic-electric transducer 20 is connected with the buoy on the water surface by a rope, and the lower end is connected with a fixed anchor to prevent the device from moving. A wireless signal transmitting device 22 is installed in the buoy to float on the water surface, and a wireless signal transmitting antenna 21 is arranged on the buoy. A wireless signal receiving device 31 and a data processing device 30 are provided, and the two are connected by a cable. The wireless signal receiving device receives the wireless signal sent by the wireless signal transmitting device and transmits it to the data processing device.

[0061] The communication distance between the wireless signal transmitting device and the wir...

Abstract

The invention discloses a swimming pool drowning life-saving intelligent system. The swimming pool drowning life-saving intelligent system comprises an intelligent drowning monitoring alarm apparatus, an underwater sound signal receiving conversion device and a data processing device. When a swimmer is in a drowning condition, the intelligent drowning monitoring alarm apparatus automatically sends a sound wave signal, the underwater sound signal receiving conversion device receives the sound wave signal sent by the intelligent drowning monitoring alarm apparatus underwater, converts the sound wave signal in to an electric signal and transmits the electric signal to the data processing device through a wired or wireless communications technology; the data processing device processes the received signal so as to precisely locate the position of a drowning man in the water, and records and displays the underwater moving track of the drowning man. The swimming pool drowning life-saving intelligent system provided by the invention has the beneficial effects that the intellectualized and automatic drowning alarm and processing device is adopted, thus the defect of the existing drowning life-saving manner is overcome, the intellectualized and automatic alarm of a drowning accident is realized, the active prevention, prewarning and in-time detection of drowning life saving are realized, and the incidence rate of the drowning accident, especially, the drowning fatal accident, can be basically avoided.

Description

technical field [0001] The invention belongs to a drowning lifesaving device, in particular to an intelligent and automatic drowning lifesaving early warning and alarm system for a swimming pool. Background technique [0002] According to the estimates of the Ministry of Health, more than 150 people die from drowning every day in my country (more than 57,000 people a year). The World Health Organization estimates more than 112,000 people a year. According to statistics from the International Life Saving Federation, millions of people are killed by water every year in the world. [0003] According to the statistics of the "Fifth National Sports Venue Census Data Bulletin" of the State Sports General Administration in 2005, "There are 850,080 sports venues of various types in various systems, industries, and various forms of ownership (excluding Hong Kong, Macao and Taiwan regions) in China. There are more than 210,000 swimming pools." Due to the large area and quantity of ...
