Detailed Description
This patent is further described below with reference to the accompanying drawings:
as shown in fig. 1-2, a height adjusting method of a smart pillow based on a sleeping posture weight air pressure characteristic line, the smart pillow comprises a bottom plate 1 for supporting, a weighing sensor 3 is arranged on the upper portion of the bottom plate 1, an air bag 4 is arranged on the upper portion of the weighing sensor 3, a sponge 2 for supporting a head is arranged on the upper portion of the air bag 4, and a pillow case 5 is wrapped outside the bottom plate 1, the weighing sensor 3, the air bag 4 and the sponge 2. The weighing sensor 3 is used for measuring the weight of the head applied on the intelligent pillow. Preferably, the weighing sensor 3 comprises four strain sensors connected in series, the four strain sensors are uniformly distributed at four corners of the bottom plate 1, and a support plate is arranged above the strain sensors.
The height of the intelligent pillow is changed by inflating or deflating the air bag 4, and the optimal support for the head and the neck is realized. In order to realize inflation and deflation, the air bag 4 is connected with an air inlet valve and an air pressure sensor through a Y-shaped air pipe, and the air inlet valve is connected with an inflator pump through an air pipe. When the air inlet valve is opened and the inflator works, the air bag 4 is inflated; when the air inlet valve is opened and the inflator does not work, the air bag 4 is deflated. The air pressure sensor can measure the air pressure value in the air bag 4 and is in direct proportion to the height of the intelligent pillow. Preferably, the XGZP6847A module is used as the barometric pressure sensor. The module is small in size, comprises an air pressure detection and signal processing circuit chip, is powered by a DC5V power supply, has a measuring range of 0-40Kpa, and outputs a linear relation between a voltage value and an air pressure value.
In order to carry out centralized control, weighing sensor 3, baroceptor, admission valve and pump connection control circuit, control circuit pass through weighing sensor 3 measure the weight that the wisdom pillow bore, through baroceptor measure the atmospheric pressure value of gasbag 4, through admission valve and pump right gasbag 4 aerify and exit.
The control circuit is provided with a pillow height adjusting method, and the pillow height adjusting method comprises the following steps:
(1) Setting a lying weight air pressure characteristic line and a side lying weight air pressure characteristic line: measuring the weight w1 and the air pressure p1 when a user lies down and feels comfortable, recording as a state S1, keeping the air pressure as p1, and measuring the weight w2 when the user lies on the side, recording as a state S2; measuring the weight w3 and the air pressure p2 when the user feels comfortable when lying on the side, recording as a state S3, keeping the air pressure at p2, measuring the weight w4 when the user lies flat, and recording as a state S4; the line segment from the state S1 to the state S4 is a lying weight air pressure characteristic line, the line segment from the state S2 to the state S3 is a side lying weight air pressure characteristic line, and the line segment from the state S1 to the state S3 is a target state line;
the state S1 is a comfortable state of the user in a lying state, and the state S3 is a comfortable state of the user in a lying state. However, the sleeping postures of the user may have diversity and may be in a state between the lying-down state and the lying-on-side state, and therefore, a line segment between the state S1 and the state S3 is defined as a target state line and is a position where the intermediate sleeping posture between the lying-down state and the lying-on-side state should be located.
(2) During steady-state operation, namely the air inlet valve and the air pump are in a closed state, when the measured air pressure p = p1 of the air bag 4, if the measured weight w of the weighing sensor 3 is less than w 1-delta, the control circuit opens the air inlet valve and starts the air pump, and when | (w-w 1) - (p-p 1) | (w 3-w 1)/(p 2-p 1) | < delta or p = p2 is satisfied, the air inlet valve and the air pump are closed, wherein delta is a state tolerance, namely a permissible change amplitude of the state;
and (2) the intelligent pillow is in a low position state, namely the measured air pressure p = p1, if the user is not lying down, namely w < w 1-delta, the height of the pillow needs to be increased, and the state (w, p) is adjusted to a target state line. Ideally, the points on the target state line should satisfy: in order to allow the actual state to float by δ above and below the target state line, (w-w 1)/(p-p 1) = (w 3-w 1)/(p 2-p 1) | < δ, the condition is satisfied. In an abnormal situation, when the measured air pressure p is increased to p2, the target state can not be reached, and the inflation process is forcibly ended.
(3) When the measured air pressure p = p2 of the air bag 4 during steady-state operation, if the measured weight w of the load cell 3 is greater than w3+ δ, the control circuit opens the intake valve, and closes the intake valve when | (w-w 1) - (p-p 1) | (w 3-w 1)/(p 2-p 1) | < δ or p = p1 is satisfied;
similar to the step (2), the step (3) processes the situation when the intelligent pillow is in the high position state. If the user is not lying on his side, i.e. w > w3+ delta, the height of the pillow needs to be lowered and the state (w, p) is adjusted to the target state line. In an abnormal condition, when the measured air pressure p is reduced to p1, the target state can not be reached, and the air discharging process is forcibly ended.
(4) During steady state operation, the measured pressure p of the air bag 4 is in the interval (p 1, p 2), if the weight w and the pressure p satisfy: l (w-w 1) - (p-p 1) (w 3-w 1)/(p 2-p 1) | < delta, and the state is kept unchanged; if the weight w and the pressure p satisfy: (w-w 1) - (p-p 1) ((w 3-w 1)/(p 2-p 1) > δ, the control circuit opening the intake valve and closing the intake valve when | (w-w 1) - (p-p 1) ((w 3-w 1)/(p 2-p 1) | < δ or p = p1 is reached; if the weight w and the pressure p satisfy: (w-w 1) - (p-p 1) ((w 3-w 1)/(p 2-p 1) < - δ), the control circuit opens the intake valve and activates the inflator, and closes the intake valve and the inflator when | (w-w 1) - (p-p 1) | (w 3-w 1)/(p 2-p 1) | < δ or p = p2 is reached.
And (4) processing the situation that the measured air pressure p of the intelligent pillow is in the interval (p 1, p 2). The states (w, p) are divided into three cases: the first case is on the target state line, no processing is performed; in the second case, the air is discharged when the air is positioned above the target state line; and in the third case, the state is below the target state line, and then the inflation is performed. Finally, the state (w, p) is adjusted to the target state line, so that the head and neck of the user are in a comfortable supporting state.
In conclusion, the scheme disclosed by the invention judges the sleeping posture of the user according to the numerical values of the weight w and the air pressure p of the intelligent pillow and the sleeping posture weight air pressure characteristic line, so that the height of the intelligent pillow is adjusted, the supporting effect of the pillow on the head and the neck in the sleeping process is improved, and the sleeping quality is improved.
