The utility model discloses an input of singlechip 9 carries out the collection of user's static parameter (like blood pressure, oxyhemoglobin saturation, rhythm of the heart scope, static gesture characteristic range) and the collection of user's motion sign parameter (like blood pressure scope, oxyhemoglobin saturation, rhythm of the heart scope, the showy time of standing vertically) with data input such as user's sex, age, weight, height drowning monitoring devices 1 through a great deal of sensors on the drowning monitoring devices 1. For example, an authorized patent CN 208030481U, "an intelligent bracelet for monitoring human body physical signs capable of being accurately positioned", discloses a miniaturized manner of monitoring human body physical signs indexes. The collected data are analyzed by the single chip microcomputer by applying the prior art, the normal range of each physical sign parameter of the user is determined, a proper judgment threshold value is generated, when the parameter value is not in the normal range, the drowning monitoring device 1 sends out a signal, and the lifesaving device 12 takes protective measures to carry out drowning lifesaving.

When a swimmer encounters drowning, the swimmer does not call for help and flap flowers hard as in a movie. Since the time for the mouth to emerge from the water is short, there is no time at all to take other actions than ventilation. When the drowning condition appears, people who can not swim can want to make way to expose the water surface from instinctive response, through pressing down the form such as arm hard, kicking legs, when taking place the drowning condition, drowned person mostly keeps upright "climbing stair" gesture, and when this gesture lasts 30s, can judge that the user is in drowned state, needs rescue at once. The standing floating time refers to the duration time that the user is in a standing posture in water, the body is approximately vertical to the water surface, and the leg action is in a stair climbing state. The normal value is typically set to 30 s. The state is detected through the DUG20 split type LVDT displacement sensor, corresponding detection values are input into the single chip microcomputer 9, and if the state occurs, an alarm is given. Drowning monitoring devices 1 uses blood pressure, rhythm of the heart and upright suspension time etc. as the monitoring object, judges the simulation whether the user is drowned to confirm the simulation result as the alarm threshold value, carry out the structure that judges and the result of the true feedback of user to whether the user is drowned and compare.
