Problems solved by technology
At present, the swimming rings on the market have various shapes, but they all maintain the design of a single circular air bag in structure, and this kind of swimming rings has great safety hazards
When the swimming ring leaks or the child is out of the swimming ring, the child is prone to the danger of drowning, and often when drowning, the child is often unable to call for help, parents and surrounding personnel to rescue and rescue

Embodiment
[0086] Step 1. The N pressure sensors (1) on the swimming ring are respectively arranged on the upper and lower layers of the outer surface of the swimming ring body (1), each layer has N / 2 sensors, and the pressure sensors (1) on the water surface will be used The group is set as group A, and the pressure sensor (1) group under the water surface is set as group B;
[0087] Let the N / 2 sensors of group A receive the force at time tn as:
[0088]
[0089] Let the N / 2 sensors of Group B receive the force at time tn as:
[0090]
[0091] Step 2. Calculate the average value avgFA of the N / 2 sensors in groups A and B at time tn tn , avgFB tn for:
[0092]
[0093]
[0094] Step 3. Calculate the variance varFA of the force on the N / 2 sensors of groups A and B at time tn tn , varFB tn for:
[0095]
[0096]
[0097] Step 4. Select varFA tn , varFB tn Medium and large values maxvar, minvar:
[0098] maxvar=max(varFA tn , varFB tn );
[0099] minvar=min(...

The invention discloses an outdoor child swim ring for prompting safety information and a safety detecting method thereof. A plurality of air bags are arranged in a swing ring body. The outdoor childswim ring further comprises pressure sensors which are evenly distributed on the upper surface of the outer portion of the swim ring body, a light-emitting alarm module and a waterproof switch which are arranged outside the swim ring body, and an air pressure sensor, a power module and a control module which are located in the swim ring body. By means of the method for detecting the safety abnormity of the swim ring, the judgment abnormity of the sensors is reduced, parents can observe the conditions of the swim ring in real time, when the swim ring leaks air, a child gets out of the swim ringor the swim ring is too far away from a cell phone, the swim ring can automatically give a sound and flash, the cell phone of the parents can vibrate and give an alarm at the same time, the parents can be reminded in time when the child is in danger during swimming, and drowning events are avoided.
Description
technical field [0001] The invention relates to the field of intelligent control systems, in particular to an outdoor children's swimming circle that prompts safety information and a safety detection method thereof. Background technique [0002] Nowadays, many parents like to take their children to swim in outdoor places such as rivers and seasides in summer. Outdoor swimming can not only allow children to enjoy the beautiful scenery, but also exercise their bodies and help them cool down in the hot summer. Although outdoor swimming is more interesting than indoor swimming, the safety of children is not well guaranteed. The tragedy of children swimming and drowning often occurs, which has to attract people's attention. [0003] For children who have not yet learned to swim, the swimming ring is the best safety guarantee for children. At present, the swimming rings on the market have various shapes, but they all maintain the design of a single circular air bag in structure, ...
