Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The currently marketed devices related to sleep data can only be used by one person in general, and if two persons are used, the data will be confused, for example: under the two conditions of sleeping on the bed, which turning-over position cannot be recorded, and which leaving-out position cannot be recorded. Basically, double beds are in many families, and inconvenience is brought to a user if only the existing technology is adopted to monitor sleep data. As shown in fig. 1, four sensors mounted at four bed feet of a bed are generally bound together to output a value, that is, only one weight value is output by the four sensors, however, when the sleep data of a sleeper is monitored in this way, it is impossible to sense which position (left area or right area) the user lies on the bed, and only the weight, the out-of-bed condition, the turning over condition, and the like of a single person can be simply sampled, but if two persons lie on the bed, the data is very confused and cannot be accurately identified.
Based on this, according to the sleep monitoring method and the sleep monitoring device provided by the embodiments of the present invention, the weights of two sleepers on the left side of the bed and the weights of two sleepers on the right side of the bed can be determined according to the input values of the sensors disposed on the two sides of the bed or near the two sides of the bed, that is, the bed is divided into the left part and the right part, and the sleeping conditions of the two sleepers on the bed are obtained according to the weights of the left part and the right part, so that the condition that only one person can be measured or the sleeping data of the two persons are recorded in a disordered manner in the.
To facilitate understanding of the present embodiment, a sleep monitoring method disclosed in the present embodiment is first described in detail:
first, it is to be described that a sleep monitoring method disclosed in the embodiment of the present invention is applied to a sleep monitoring apparatus 200, the sleep monitoring apparatus 200 includes a plurality of sensors 210, and the plurality of sensors 210 are respectively disposed at both sides of a bed or near both sides of the bed, that is, a part of the plurality of sensors 210 measures a pressure value at the left side of the bed or near the left side of the bed, and the remaining sensors 210 of the plurality of sensors 210 except the sensor 210 measuring a pressure value at the left side of the bed or near the left side of the bed measure a pressure value at the right side of the bed or near the right side of the bed. Wherein the plurality of sensors 210 may be pressure sensors.
As an example, referring to fig. 2, 3 and 4, taking the example that the plurality of sensors 210 are 4 sensors and four sensors are respectively disposed at four bed legs near both sides of the bed, in fig. 2 and 3, the first sensor group a, the second sensor group B, the third sensor group C and the fourth sensor group D each include one sensor 210, the support base 10 and the sensor decorative cover 20, the first sensor group a and the second sensor group B are at the left side bed leg of the bed, the sensors 210 in the first sensor group a and the sensors 210 in the second sensor group B measure the weight change on the left side of the bed, the third sensor group C and the fourth sensor group D are at the left side bed leg of the bed, the sensors 210 in the third sensor group C and the sensors 210 in the fourth sensor group D measure the weight change on the right side of the bed, that is, the bed can be divided into two left and right parts, the left and right regions. The output values of the sensors 210 of the first sensor group a, the sensors 210 of the second sensor group B, the sensors 210 of the third sensor group C and the sensors 210 of the fourth sensor group D are converted into digital values by analog-to-digital converters (ADCs) connected to the main controller 220, and then input to the main controller 220. In addition, the supporting seat 10 can be made of a hardware die casting, so that the structural strength can be ensured, and the weight of a bed and a human body can be borne.
Referring to fig. 5, a flow chart of a sleep monitoring method is shown, which includes:
s110: input values of a plurality of sensors are acquired.
Specifically, input values of the plurality of sensors 210 in the sleep monitoring device 200 are acquired, i.e., input values of the sensors 210 on the left side of the bed and input values of the sensors 210 on the right side of the bed are acquired. It should be noted that the input value may be an input value output by each sensor 210, may be an input value output by a plurality of sensors 210, or may have other input conditions for a plurality of sensors 210, which is not limited herein.
S120: the weight of the first sleeper and the second sleeper on the left side of the bed and the weight of the first sleeper and the second sleeper on the right side of the bed are determined according to input values of a plurality of sensors.
In some embodiments, step S120 specifically includes: acquiring a first input value of the sensor 210 at or near the left side of the bed and a second input value of the sensor 210 at or near the right side of the bed; acquiring a third input value of the sensor 210 at the left side of the bed or near the left side of the bed and a fourth input value of the sensor 210 at the right side of the bed or near the left side of the bed; and calculating the weight of the sleeper on the left side of the bed and the weight of the sleeper on the right side of the bed based on the preset relationship according to the first input value, the second input value, the third input value and the fourth input value.
Wherein, the preset relationship is as follows: the difference between the fourth input value and the second input value is the difference between the weight of the sleeper on the right side of the bed and the weight of the sleeper on the left side of the bed; the difference between the third input value and the first input value is the weight of the sleeper on the right side of the bed.
Further, the method also comprises the following steps: the weight of a sleeper on the left side of the bed and the weight of the sleeper on the right side of the bed are corrected.
It is noted that the sleep monitoring method of the present invention further comprises: the weight on the left side of the bed and the weight on the right side of the bed are stored as base points for the next measurement.
As an example, the sensor 210 at the left side of the bed or near the left side of the bed outputs one input value, and the sensor 210 at the right side of the bed or near the right side of the bed outputs one input value, for example, when capturing the base point, that is, with respect to the current time, the capture base point refers to the input value at the previous moment: the ADC of the base point corresponding to the 1 st group of measurement channels is Z1; the ADC of the base point corresponding to the 2 nd group of measurement channels is Z2; where group 1 is the sensor 210 input at the left side of the bed or near the left side of the bed and the second group is the sensor 210 input at the right side of the bed or near the right side of the bed, the same applies when measuring as follows. During measurement: the ADC inner code measured in group 1 is A1; the ADC inner code measured in group 2 was A2.
In summary, the ADC obtained when weighing and the ADC obtained when grabbing the base point can calculate 2 variation values, that is, the variation value of the input value at the left side of the bed or the left side close to the bed, the variation value of the input value at the right side of the bed or the right side close to the bed, and define 2 variation values as VAI1 and VAI3, respectively.
And obtaining a relation formula:
VAI3–VAI1=Z2-A2,VAI3=Z1-A1;
definition Z1-a 1-N1Z 2-a 2-N2 the above relation (r) can be simplified to relation (c):
VAI3–VAI1=N2,VAI3=N1;
the variable of each loadcell can be obtained by the relation: VAI1 ═ N1-N2; VAI3 ═ N1.
When corrected, it is known that:
the correction gain value corresponding to loadcell1 is K1;
the correction gain value corresponding to the Loadcell2 is K2;
the calculation formula of the weight is as follows: Weight-K2 VAI1+ K1 VAI 3;
Weight=K2*(N1-N2)+K1*N1。
s130: judging the sleeping conditions of the first sleeper and the second sleeper in the bed according to the weights of the first sleeper and the second sleeper on the left side of the bed and the weights of the first sleeper and the second sleeper on the right side of the bed.
In some embodiments, as shown in fig. 2, 3, 4, and 6, the plurality of sensors 210 are four sensors respectively disposed at the bed foot, and the four sensors are half-bridge sensors, the first half-bridge sensor and the second half-bridge sensor form a full-bridge circuit to output the sleeping condition of the first sleeper and the sleeping condition of the second sleeper on the left side of the bed, the third half-bridge sensor and the fourth half-bridge sensor form a full-bridge circuit to output the sleeping condition of the first sleeper and the sleeping condition of the second sleeper on the right side of the bed, and as shown in fig. 6, (a) the first half-bridge sensor Cell1 and the second half-bridge sensor Cell2 form a full-bridge circuit, and (b) the first half-bridge sensor Cell3 and the second half-bridge sensor Cell4 form a full-bridge circuit.
In combination with the structure of the sleep monitoring device, the step of determining the sleeping conditions of the first sleeper and the second sleeper in the bed specifically includes:
judging the left side or the right side of the first sleeper on the bed and the weight of the first sleeper according to the weight of the first sleeper on the left side of the bed and the weight of the first sleeper on the right side of the bed;
when at least one of the input values of the first half-bridge sensor and the second half-bridge sensor and the input values of the third half-bridge sensor and the fourth half-bridge sensor is changed, judging whether the condition that the sum of the weight of the current left side of the bed and the weight of the current right side of the bed is larger than the sum of the weight of the left side of the bed at the previous moment and the weight of the right side of the bed at the previous moment is met, and the difference value between the sum of the weight of the current left side of the bed and the weight of the current right side of the bed and the sum of the weight of the left side of the bed at the previous moment and the weight of the right; if so, determining that the second sleeper exists in the bed, and determining the left side or the right side of the second sleeper in the bed and obtaining the weight of the second sleeper according to the weight of the current left side of the bed and the weight of the current right side of the bed and the weight of the previous left side of the bed and the weight of the previous right side of the bed.
As an example, referring to fig. 7, the first measured weight may be represented by W1, the first weight on the left side of the bed may be represented by wcarh 1, the first weight on the right side of the bed may be represented by wcarh 1, where W1 ═ wcarh 1+ wcarh 1, and so on. The first sleeper may be represented by P1, the first sleeper's weight may be represented by WP1, the second sleeper may be represented by P2, and the first sleeper's weight may be represented by WP 2. Specifically, when there is at least one change of wye 1 and wye 1, that is, there is a person moving in the bed, it can be determined that there is P1, WP1 is W1 is W left 1+ W right 1, and W left 1 and wye 1 can also be determined by the size that P1 is actually on the left and right sides, that is, when wye 1> wye 1, P1 is on the left side of the bed, when wye 1< wye 1, P1 is on the right side of the bed, when measured for the second time, W2> W1, and W2-W1> R1, where R1 here can be preset, and the main range is the weight range of the person, for example: the weight of an adult is 40-100 kg, the weight of a child is 5-40 kg, and the weight range of other people is equal. When the criterion is established, P2 exists. At the same time, the weight of P2 and which area on the bed it is in, i.e., P2 is to the left when (Wleft 2-Wleft 1) > (Wright 2-Wright 1). When (Wleft 2-Wleft 1) < (Wright 2-Wright 1), P2 is on the right side. WP2 ═ W left 2-W left 1) + (W right 2-W right 1).
Further, the method also comprises the following steps: when the first sleeper and the second sleeper are determined to be in the bed, judging whether the difference value between the weight of the current left side of the bed and the weight of the left side of the bed at the previous moment is larger than the difference value between the weight of the current right side of the bed and the weight of the right side of the bed at the previous moment, the weight of the current left side of the bed is smaller than the weight of the left side of the bed at the previous moment, and the weight of the current right side of the bed is smaller than the weight of the right side of the bed at the previous moment; if so, it is determined that the sleeper on the left side of the bed is out of bed. Similarly, it can be determined that the sleeper on the right side of the bed is out of the bed.
Specifically, when Wleft 3< Wleft 2, and Wright 3< Wright 2, and | W left 3-Wleft 2| > | W right 3-Wright 2|, it is determined that the sleeper on the left side of the bed is out of the bed. When Wleft 3> Wleft 2, and Wright 3> Wright 2, and | W left 3-Wleft 2| < | W right 3-Wright 2|, it is determined that the sleeper on the right side of the bed is out of bed.
As another example, when determining that there are P1 and P2 in the bed, determining whether to leave the bed further comprises: w4< W2, and W4-W2> T, where T here may be preset, the main range being the weight range of a human body, for example: the weight of an adult is 40-100 kg, the weight of a child is 5-40 kg, and the weight range of other people is equal. Then judging whether P1 or P2 leaves the bed, if one of the two persons is on the left side and one is on the right side, judging that the sleeper on the right side of the bed leaves the bed when the sleeper passes through | W left 3-W left 2| < | W right 3-W right 2|, and if | W left 3-W left 2| > | W right 3-W right 2|, judging that the sleeper on the left side of the bed leaves the bed. If two persons are on the left side and the weight difference between the two persons is large, the person can be judged to be P2 out of bed by the changing conditions of | W left 4-W left 2|, | W right 4-W right 2|, if | W left 4-W left 2| changes, if the changes accord with the weight condition of P2 on the right side of the bed, and if the changes accord with the weight of P1 on the left side of the bed, P1 out of bed, and similarly, if the two persons are on the right side, the person can be judged to be P1 out of bed by the changing conditions of | W right 4-W right 2|, and the weights of P1 and P2 on the right side of the bed. If two persons are on the left side and the weight difference between the two persons is not great, the off-bed condition of P1 and P2 can be measured by installing a distance measuring sensor on both sides of the bed, in combination with the weight measuring sensor of the present invention. Variations on the above described examples are also within the scope of the invention.
Further, the method also comprises the following steps: judging whether the difference between the weight of the current left side of the bed and the weight of the right side of the bed at the previous moment is larger than the difference between the weight of the current right side of the bed and the weight of the right side of the bed at the previous moment; if so, judging that the sleeper turns left.
Specifically, no matter 1 or 2 sleepers are in the bed, as long as the difference value between the weight on the left side of the bed at present and the weight on the left side of the bed at the previous moment is judged to be larger than the difference value between the weight on the right side of the bed at present and the weight on the right side of the bed at the previous moment, the sleeper is judged to turn over to the left, and otherwise, the sleeper is judged to turn over to the right.
As an example, if a person is in the bed, using W5 as the weight currently in the bed, W left 5 as the weight currently on the left side of the bed, and W right 5 as the weight currently on the right side of the bed, using W1 as the weight value immediately before the bed, (W left 5-W left 1) > (W right 5-W right 1), i.e., the load on the left side of the bed increases, and the load on the right side of the bed decreases, it can be determined that the person in the bed turns left. Similarly, when two persons are in bed, W6 is the weight of the two persons in bed, Woofer 6 is the sum of the weights of the two persons on the left side of the bed, Woofer 6 is the sum of the weights of the two persons on the right side of the bed, and W6-Woofer 1 are compared, and the comparison value is a change value and is irrelevant to the magnitude of the value, so that even if the two persons are in bed at the same time, whether the sleeper turns left or right can be judged through the above formula. In addition, because the sleeper is dragged by muscle power in the process of turning over, the pressure of the sleeper to the sensor changes, and the pressure identified by the sensor is the gravity of the sleeper only when the sleeper is finally stable. In the process, the pressure change caused by the same traction is different from the instantaneous pressure change distributed to the left area and the right area, so that if two persons are determined to be in the bed, the signals output by the instantaneous fluctuation of the sensor are analyzed by the detection circuit on the main controller to judge which area is turned over. For example, when the signal fluctuation output by the first half-bridge sensor and the second half-bridge sensor is relatively large, it is described that the instantaneous weight change of the left zone is relatively large, the sleeper in which the left zone is located is performing the turning action, and when the signal fluctuation output by the third half-bridge sensor and the fourth half-bridge sensor is relatively large, the sleeper in which the right zone is located is performing the turning action. By the judgment, the person on the left side or the right side of the bed can be accurately judged to turn over, and the turning sleeper turns over in which direction. And can accurately find out which sleeper turns over by combining the identity of the sleeper on the left/right side of the bed determined before.
When the sleeper sleeps deeply or shallowly, whether the sleeper sleeps deeply or shallowly can be judged by recording the turning-over condition and the leaving-bed condition, the turning-over condition and the leaving-bed condition are rare when the sleeper sleeps deeply, and the turning-over condition and the leaving-bed condition are rare when the sleeper sleeps shallowly.
According to the sleep monitoring method, the time when the user turns over on the left side or the right side of the bed, the time when the user leaves the bed on the left side of the bed or the time when the user leaves the bed on the right side of the bed can be recorded, the user can be judged to wake up and leave the bed after the user leaves the bed for a long time, an alarm clock is set according to the habit of the user for reminding, the user only needs to leave the bed, and important matters are prevented from being missed due to bed-dependent reasons. Or, when the sleeper in bed includes children, the turning-over condition of the children is monitored in a key mode, if the children are always in one state, the normal growth of the children can be influenced, and the user is reminded to adjust the sleeping posture of the children by adjusting the auxiliary equipment in the bedroom in time. Such as: the position of the night light, the left and right side adjustment of the child in the bed, etc.
On the other hand, the sleep monitoring method can also be used for only one sleeper, and can obtain the weight, the turning-over condition and the bed leaving condition of the first sleeper so as to judge whether the sleeper is old or not, and which time is deep sleep and which time is shallow sleep.
In addition, after the first sleeper leaves the bed, the sleep condition of the second sleeper, such as in which area to turn over or leave the bed, may also be monitored separately.
