A plurality of air bags, a pressure sensor 1, a waterproof buzzer 5 and a waterproof switch 9 of a waterproof LED lamp 3 are arranged in the swim ring body 10, and an air pressure sensor 2, a power supply module 4 and a control module are arranged on the outer surface of the swim ring body 10; the core circuit part 6, the man-machine interaction part 7 and the antenna part 8 are located inside the swim ring body 10.
A suggestion safety information's outdoor children's water wing's safety inspection's principle:
the pressure sensors 1 are respectively arranged on the upper layer and the lower layer of the outer surface of the swim ring body 10, each layer is provided with N/2 sensors, the group of the pressure sensors 1 on the water surface is set as group A, and the group of the pressure sensors 1 under the water surface is set as group B when in use;
the first task of the multi-sensor data fusion algorithm is to distinguish the postures:
z1: which side is under water when the swim ring is in a horizontal posture during single-sided floating?
Z2: which side is under water when the swim ring is in longitudinal posture during forward swimming?
The second task is to perform data fusion on the basis of completion of the first task,
in the middle, the principle of the first task is that the pressure sensor is a point sensor, the force obtained by the pressure sensor group on the water surface is uneven stress, one or 2 arms or 4 limbs are possibly put on the sensor point, and the difference is large; the pressure sensor group under the water surface is influenced by the overall pressure of the water body, so that the force is relatively uniformly applied, and therefore, the working principle of the first task is to adopt a variance comparison method.
Examples
Step one, N pressure sensors (1) on a swim ring are respectively arranged on the upper layer and the lower layer of the outer surface of a swim ring body (1), each layer is provided with N/2 sensors, a group of the pressure sensors (1) on the water surface is set as a group A, and a group of the pressure sensors (1) under the water surface is set as a group B when the swim ring is used;
let the force received by the group A N/2 sensors at time tn be:
let the force received by the N/2 sensors of group B at time tn be:
step two, calculating the average value avgFA of the force received by the N/2 sensor of the A, B group at the time tntn、avgFBtnComprises the following steps:
step three, calculating the variance avgFA of the force applied to the N/2 sensor of the A, B group at the time tntn、avgFBtnComprises the following steps:
step four, selecting varFAtn、varFBtnMedium-size values maxvar, minvar:
maxvar＝max(varFAtn，varFBtn)
minvar＝min(varFAtn，varFBtn)
wherein the symbols max and min represent the process of selecting the maximum and minimum values;
step five, calculating a variance ratio Pvar:
step six, judging the state
Setting a threshold Tvar;
if Pvar is larger than Tvar, judging that the single side floats, the swim ring is in a transverse posture, and judging whether the A and B sides are on the upper side and the other side is on the lower side according to the side corresponding to maxvar;
if Pvar < ═ Tvar, then the swimming stroke is determined to be forward, the swim ring is in the longitudinal direction, and the maximum force of all the N sensors at the time is calculated:
step seven, if the swimming ring floats on a single surface and is in a transverse posture, calculating the stress sum totalfC of all sensors on the surface under the water surfacetn；
Then, the value is taken as the force value F applied to the swim ring in the vertical direction at the momenttnThe device is used for further judging the state of a user;
if the swimming life-buoy is in a forward swimming posture and the swimming circle is in a longitudinal posture, the data of the sensor at the moment is the transverse pressure of the water pressure, the transverse pressure is related to the underwater depth of the sensor, and the underwater depth of the sensor is also related to the stress value F of the swimming circle in the vertical directiontnIs a linear relationship, then using the result of step 6 yields Ftn：
Ftn＝Coh*maxFtn+Cob；
Coh and Cob are constants, which are related to the material and radius of the swim ring, and are required to be tested at different F by continuous tests in a laboratory after the material and radius of the swim ring are determinedtnAnd maxFtnThe Coh and Cob are calculated by a linear fitting method;
n-20, i.e., 20 external pressure sensors; tvar ═ 2; coh and Cob are constants, which are related to the material and diameter of the swim ring, in this embodiment, the swim ring material is plastic, the thickness is 1mm, the diameter of the swim ring balloon is 30cm, the overall diameter of the swim ring is 90cm, at this moment, Coh is 63, and Cob is-11;
step eight, judging abnormity
totalFC in either lateral statetnAnd F in the longitudinal directiontmThe buoyancy of water to the swim ring is reflected under users with different weights, before the swim ring is used, the force under a normal state is set under the condition that a guardian confirms the safety condition, and when the swim ring is used, the buoyancy cannot be changed too much under the condition that the guardian judges whether the swim ring is transverse or longitudinal;
if the loss is too large, the user is indicated to be separated from the swim ring, and then the danger can be judged to be generated and the alarm is required;
if the increase is too large, an overweight object presses the swim ring, or the swim ring loses buoyancy and falls in the water, and the dangerous condition also needs to be alarmed;
therefore, when the safety is confirmed by the guardian first, totalFC in the lateral direction is applied to the swim ring of the child in the normal statetnAnd F in the longitudinal directiontnSetting is carried out to obtain a standard value which is different from person to person, namely totalFC in a transverse statetnNormal and F in the longitudinal statetn_normal；
Then setting an upper variable threshold ratio Td _ up, a lower variable threshold ratio Td _ down and a time threshold T _ danger;
when in use, the horizontal state or the longitudinal state is continuously detected;
if the current state is the horizontal state, then continuing to judge the current totalfCtnAnd totalFC of the settingtnDifference of normal with totalfCtnA normal ratio, if the upper threshold ratio Td up and the lower threshold ratio Td down are varied and the time is greater than or equal to the time threshold T _ danger, then an alarm is issued;
if the state is the longitudinal state, then continuing to judge the current stateF of (A)tnAnd difference of set Ftn _ normal, and FtnA normal ratio, if the upper threshold ratio Td up and the lower threshold ratio Td down are varied and the time is greater than or equal to the time threshold T _ danger, then an alarm is issued;
when the distance between the swim ring and the mobile phone exceeds the safety range and the time is more than or equal to the time threshold value T _ danger, an alarm is given, and the method is characterized in that the information of the positioning device of the swim ring is compared with the positioning information of the mobile phone of the guardian.
The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
