Drowning prevention pre-warning apparatus and method that combines posture, water depth and time information

Abstract

The present invention relates to a drowning prevention pre-warning apparatus and method that combines posture, water depth and time information. The apparatus comprises a wristband worn on a hand of aswimmer and a monitoring terminal for receiving a processing signal. An intelligent chip, a pressure sensor, a gyroscope, a timer, a battery, and a communication module are disposed inside the wristband. The intelligent chip is in communication connection with the monitoring terminal by using the communication module. The pressure sensor, the gyroscope, the timer, and the battery are all connected to the intelligent chip. Whether a user is drowning is comprehensively judged by detecting three parameters of an underwater depth, an underwater posture, and an underwater time of a swimmer, so that drowning judging accuracy is improved, and misinformation and misrepresentation of swimmer drowning are reduced.

Description

technical field [0001] The invention relates to the technical field of alarm equipment, in particular to an anti-drowning early warning device and method for integrating posture, water depth and time information. Background technique [0002] The judgment basis of the relatively mature water shield anti-drowning warning system in China is that the smart chip is embedded in the swimming cap. When the swimming cap is above the water surface, it will continuously send signals to the monitoring terminal, and when the swimming cap is below the water surface, it will stop sending. signal, and it is judged to be in a disconnected state, and the timing starts at this time. If the monitoring end has not received the signal after the system default time or user-defined time has passed, that is, the swimming cap is still under the water surface, it is judged that the user is drowning. First, the drowning criterion is based on the loss of contact as the criterion for judgment, and it do...

Problems solved by technology

The average person's resting heart rate is 60 beats per minute to 100 beats per minute. It is normal for the heart rate to increase during exercise, especially swimming. However, the heart rate varies greatly from person to person, especially when the heart rate is near drowning and struggling. It is impossible to define an accurate one. The upper limit of the upper limit value to judge whether to drown, so it is not practical to judge whether to drown by monitoring the heart rate
