Pressure change judgment formula
Rate of pressure changeWhereinIs the initial timeThe value of the pressure that is detected is,Is carried out for a period of timeA later detected pressure value. As determined by a large amount of experimental data, when the pressure was within 5 seconds (i.eSeconds) continuously lower than 100 g (initial set normal wearing pressure lower limit value) And the rate of pressure dropExceeding 10 grams per second (preset pressure drop rate threshold value) In this case, it is determined that the arm band 3 may slip. For example, ifThe weight of the powder is calculated as the weight of the powder,Gram (g) thenGram/second equivalentAnd is also provided withAnd triggering the subsequent anti-falling action.
Air bag body 11 inflation amount calculation formula (approximate calculation)
Let the circumference of the inner ring of the arm band 3 be(In cm), the airbag body 11 has a desired thickness after inflation of(Unit: cm) the width of the balloon body 11 is(Unit: cm), the air bag body 11 is inflated. Experimental optimization shows that for common arm band 3 sizes, such as the circumference of the inner ring of the arm band 3Cm, design ideal thickness of the inflated airbag body 11Cm, widthCm, calculate the available inflation volumeIn practical application, the milliliter can be further finely adjusted according to the specification of the arm band 3 and the required holding force, for example, the milliliter can be selectedMilliliters are used as a standard inflation range to ensure that the airbag body 11, when inflated, provides sufficient holding force to prevent further slippage of the armband 3 without undue stress on the wearer.
Calculation of inflation time (based on inflation flow)
The charge flow rate of the charge pump 13 is known(In ml/s), depending on the amount of inflation requiredCalculating the inflation time. For the selected inflation source, its inflation flow rateMl/s, in combination with the selected inflation volume range described aboveMilliliters, can obtain the inflation timeIn the second, the inflation time can be set to be within 2-3 seconds in the actual control, so that the slip situation is prevented from being worsened rapidly and effectively in the initial stage of the slip of the arm band 3, and meanwhile, the bad influence on the arm band 3 and the wearer caused by the too-rapid inflation is avoided.
The working principle is that when the pressure value detected by the pressure detection unit 17 reaches a preset slip threshold value, a trigger signal is immediately sent to the control unit 16. After receiving the signal, the control unit 16 starts the inflator 13, simultaneously opens the gas control valve 14, and controls the airbag body 11 to inflate according to the preset inflation amount and inflation time. During inflation, the pressure detecting unit 17 continuously monitors the pressure change, and when the pressure rises to the normal wearing range (e.g. 150-200 g), the control unit 16 stops the operation of the inflator 13, and closes the gas control valve 14 to keep the gas pressure in the airbag body 11 stable. If the pressure falls below the threshold again within a period of time (e.g. 10 seconds) after inflation, the control unit 16 may either restart the inflation procedure or issue an alarm signal to alert the user to re-wear the arm band 3.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
