Design And Development Of The Drowning Alarm System

With the continuous advancement of society and the gradual improvement of people’s living standards,the national health consciousness has gradually awakened,and the pursuit of physical beauty has been increasing.More and more people have developed good exercise habits.Under the stimulation of people’s needs,various commercial sports operators are increasing,and swimming pools are one of them.At the same time,the swimming pool drowning incident showed a high incidence.Although many swimming pools employ professional lifeguards,given the large number of people in the pool,lifeguards are often difficult to detect and respond to in the first time in the event of a drowning.Therefore,it is of great practical value to study how to find the drowning person in time,show the location of the drowning water and inform the lifeguard to take rescue action,which can provide a strong guarantee for people’s life safety.With the continuous advancement of society and the gradual improvement of people’s living standards,the national health consciousness has gradually awakened,and the pursuit of physical beauty has been increasing.More and more people have developed good exercise habits.Under the stimulation of people’s needs,various commercial sports operators are increasing,and swimming pools are one of them.At the same time,the swimming pool drowning incident showed a high incidence.Although many swimming pools employ professional lifeguards,given the large number of people in the pool,lifeguards are often difficult to detect and respond to in the first time in the event of a drowning.Therefore,it is of great practical value to study how to find the drowning person in time,show the location of the drowning water and inform the lifeguard to take rescue action,which can provide a strong guarantee for people’s life safety.To this end,this paper studies a set of alarm and positioning system that can automatically detect the pool water accident,which consists of two parts: the sports bracelet and the monitoring alarm equipment.The sports bracelet includes a heart rate monitoring module,a water immersion duration module,an alarm module,and the monitoring alarm device includes a positioning module and a host computer processing software.When the swimmer is unable to rescue the drowning water,the system triggers the synchronous alarm processing of the upper computer and the wristband through the judgment of the relevant data,and uses the informational means to monitor the swimming crowd,prompting the drowning danger by sound and light,and matching with the positioning of the positioning system.The lifeguard suspects the location information of the drowning person,improves the efficiency of personnel search and rescue,and also reduces the observation work intensity of the lifeguard.The drowning alarm system solution takes into account the complex environment of the swimming pool,integrates the physiological characteristics of the human body’s hydrophobic reaction,embedded technology,wireless positioning technology and computer technology,and discusses in detail the design and implementation process of the automatic alarm and positioning system for the swimming pool.The system was quickly developed using the Arduino development board to realize the following functions: 1.The system automatically judges whether the swimmer has drowning conditions;2.The upper computer and the wristband synchronously stratify the alarm;3.The positioning search and rescue.In the application software,all the bracelets in the swimming pool can be monitored to provide a safe and entertaining environment for swimmers.
