Background
With the change of science and technology, more and more products based on the application of vibration sensing technology to vital sign monitoring emerge like bamboo shoots in the spring after rain. The long-term monitoring requirement can be met because the subject does not need to wear any sensors on his body. Based on the signal capturing mode, the optimal use scene is used in a sleep state, so that a large number of products (such as a vibration monitoring cushion) based on the vibration sensing technology applied to vital sign monitoring, particularly sleep monitoring, emerge. However, since the vibration sensor is sensitive to vibration, it is easily interfered by the external environment, and thus there is a great challenge when two or more persons lie on the same bed.
As shown in fig. 1, assume that a subject a is a subject who uses a vibration monitoring pad for vital sign monitoring, the subject a and a non-subject B sleep on the same bed, the vibration monitoring pad is placed on the bed, and the subject a lies on the vibration monitoring pad. When the non-subject B and the subject A are very close to each other and both lie on the vibration monitoring pad, the vital sign signals of the non-subject B are mixed with the original signals collected by the vibration monitoring pad, and the original signal components of the subject A and the non-subject B are difficult to peel off, so that the measurement result of the subject A is influenced and even a diagnosis error is caused; if the non-subject B does not lie on the vibration monitoring pad, but the non-subject B does physical movement to different degrees, the final vibration transmitted to the vibration monitoring pad can also introduce a signal with the same signal energy amplitude as the subject A, and at the moment, the original signal components of the subject A and the non-subject B are difficult to peel off, which also influences the measurement result and even causes diagnosis error; there are more complex measurement effects when the two scenarios are combined. Vibration monitoring pads present a major challenge in application scenarios where two or more people lie on the same bed.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
The first embodiment is as follows:

S101, acquiring vital sign monitoring data of a first object acquired by a vibration sensor and distance information acquired by a distance measurement module, wherein the distance information is used for judging whether a second object interferes with the acquired vital sign monitoring data of the first object.
In the first embodiment of the present invention, the first object is a subject, and the second object is a non-subject, as shown in fig. 3, the first object and the second object are laid on the same bed or mattress. The vibration sensor 1011 is configured to be placed under the body of a first subject a in a supine, prone, side lying or semi lying state, and specifically may be configured to be placed in contact with the shoulder, back, waist or hip of the first subject. The first ranging module 1012 of the pair of ranging modules is configured to be placed anywhere on the body of the second object B, such as in a coat pocket, strapped to a shoulder, strapped to a belt, worn on the wrist, etc. The second one 1013 of the pair is configured to be placed in any fixed position (e.g. any position in the mattress plane, a foot position, or even some position not belonging to a region of the bed), shown in fig. 3 as a headrest edge position placed on the first object a side. The second object may be one or more.
The first ranging module in the ranging module pair is a signal transmitting end, and the second ranging module is a signal receiving end, but it is also possible that the first ranging module is a signal receiving end, and the second ranging module is a signal transmitting end.
The distance measurement module pair can be any module which can be used for measuring distance, such as an infrared distance measurement module pair, an ultrasonic distance measurement module pair, an acoustic distance measurement module pair and the like, and a non-radiative distance measurement scheme is preferred in consideration of human health, such as the infrared distance measurement module pair.
In the first embodiment of the present invention, in order to obtain a more accurate positioning effect, the distance information may be collected by a plurality of sets of ranging modules. The multiple groups of ranging module pairs can comprise a second ranging module and a plurality of first ranging modules, and each second object is provided with a plurality of first ranging modules; alternatively, the plurality of ranging module pairs may include a first ranging module and a plurality of second ranging modules, each second object is configured with a first ranging module, and the plurality of second ranging modules are configured to be placed at a plurality of different arbitrary fixed positions, for example, a plurality of different positions of the plurality of second ranging modules on the mattress plane, etc.; alternatively, the plurality of ranging module pairs may include a plurality of first ranging modules and a plurality of second ranging modules, each second object being configured with the plurality of first ranging modules, the plurality of second ranging modules being configured to be placed at a plurality of different arbitrary fixed positions.
And when the distance information is acquired by the plurality of groups of distance measuring modules, the distance information acquired by the plurality of groups of distance measuring modules is comprehensively calculated to obtain final distance information. For example, the average value of the distance information collected by the multiple groups of ranging modules is used as the final distance information.
The vibration sensor is one or more of an acceleration sensor, a velocity sensor, a displacement sensor, a pressure sensor, a strain sensor, or a sensor that equivalently converts a physical quantity based on acceleration, velocity, pressure, or displacement. The strain sensor may be a fibre optic sensor. The optical fiber sensor in the first embodiment of the present invention may have an appearance of a mat.
And S102, judging whether the second object can interfere with the acquired vital sign monitoring data of the first object or not according to the distance information, if so, processing the interference caused by the second object to the acquired vital sign monitoring data of the first object, and if not, directly returning to S101.
Please refer to fig. 4, which is a schematic diagram illustrating that when the second ranging module of the ranging module pair is configured to be disposed at the first object side (e.g., the edge of the bed head), it is determined whether the distance information is smaller than the predetermined threshold. The second ranging module 1013 is used as a center of a circle, a circle is drawn with a suitable radius r, a boundary between an arc and a bed edge is taken as a boundary, as shown by a shaded portion in the figure, the region is defined as an affected region, that is, if the first ranging module 1012 enters the region during sleep of the second subject, the second subject is considered to cause interference on the acquired vital sign monitoring data of the first subject. At this time, since the second ranging module is located at the first object side, in this scenario, the determining whether the second object will cause interference to the acquired vital sign monitoring data of the first object according to the distance information may specifically be:
and judging whether the distance information is smaller than a preset threshold value or not, if so, judging that the second object can interfere the acquired vital sign monitoring data of the first object, wherein the preset threshold value is the distance acquired by the distance measurement module when the second object possibly lies on the vibration sensor or the distance between the second object and the vibration sensor is smaller than an empirical value. The empirical value is the interval at which the second subject does not lie on the vibration sensor but is relatively close to the vibration sensor, which would interfere with the vital sign monitoring data of the first subject. The preset threshold may be a maximum value, a minimum value, an average value in a period of time, and the like of a distance that the second object may lie on the vibration sensor, which is measured in advance after the actual scene simulation. In this embodiment, it may be the minimum value.
Please refer to fig. 5, which is a schematic diagram illustrating that when the first ranging module of the ranging module pair is configured to be disposed at the second object side (e.g., the edge of the bed head), it is determined whether the distance information is greater than the predetermined threshold. Taking the second distance measurement module 1013 as a center of a circle, drawing a circle with a suitable radius r, taking the boundary between the circular arc and the bed edge as a boundary, as shown by the shaded portion in the figure, defining the area as an affected area, that is, if the second object enters the area during sleep, we consider that the second object will interfere with the acquired vital sign monitoring data of the first object. At this time, since the second ranging module is located at the second object side, in this scenario, the determining whether the second object interferes with the acquired vital sign monitoring data of the first object according to the distance information may specifically be:
and judging whether the distance information is larger than a preset threshold value or not, if so, judging that the second object can interfere the acquired vital sign monitoring data of the first object, wherein the preset threshold value is the distance acquired by the distance measurement module when the second object possibly lies on the vibration sensor or the distance between the second object and the vibration sensor is smaller than an empirical value. The empirical value is the interval at which the second subject does not lie on the vibration sensor but is relatively close to the vibration sensor, which would interfere with the vital sign monitoring data of the first subject. The preset threshold may be a maximum value, a minimum value, an intermediate value between the maximum value and the minimum value, and the like of a distance that the second object may lie on the vibration sensor, which are measured in advance after the actual scene simulation.

Referring to fig. 6, in a first embodiment of the present invention, a second ranging module of the pair of vibration sensor and ranging module may be built into a mat, the mat including a central sleep test zone and an air bag at one or both side edges of the mat, and when the mat includes an air bag at one side edge of the mat, a second object is laid beside the air bag. The cushion also comprises an air pressure adjusting module connected with the air bag vent valve and used for adjusting the air pressure value in the air bag.
In this scenario, the determining, according to the distance information, whether the second subject interferes with the acquired vital sign monitoring data of the first subject may specifically be:
and judging whether the distance information is smaller than a preset threshold value or not, if so, judging that the second object can interfere the acquired vital sign monitoring data of the first object, and the preset threshold value is the distance that the second object can lie on the vibration sensor. The preset threshold may be a maximum value, a minimum value, an intermediate value between the maximum value and the minimum value, or the like, which is measured in advance to obtain a distance that the second object may lie on the vibration sensor. In this embodiment, it may be the minimum value.
In the first embodiment of the present invention, before or after S101, the method may further include the following steps:
receiving an instruction of manually controlling the air bag;
controlling the air pressure adjusting module to start working and inflating the air bag;
controlling a pressure measuring module to measure the air pressure value in the air bag;
and judging whether the air bag reaches the set air pressure value, if so, stopping inflating the air bag by the air pressure adjusting module, so as to prevent the second object from approaching or even pressing the cushion in the sleeping process from influencing the test result.
In the first embodiment of the present invention, the processing of the interference caused by the second object on the collected vital sign monitoring data of the first object may specifically be:
determining the vital sign monitoring data of the first subject acquired within a time period of interference caused by the second subject on the acquired vital sign monitoring data of the first subject as invalid data;
controlling the air pressure adjusting module to start working and inflating the air bag;
controlling a pressure measuring module to measure the air pressure value in the air bag;
and judging whether the air bag reaches the set air pressure value, if so, stopping inflating the air bag by the air pressure adjusting module, and returning to the step S101.
The processing of the interference caused by the second object on the acquired vital sign monitoring data of the first object may also be:
s1031, determining the vital sign monitoring data of the first object, which is acquired within a time period of interference caused by the second object on the acquired vital sign monitoring data of the first object, as invalid data;

As shown in fig. 6, the second object is at a distance l from the mat, and the preset threshold is r; l can be the linear distance between the first ranging module and the second ranging module or the calculated distance mat of the first ranging moduleThe distance of the edges, etc., where the linear distance l between the first ranging module and the second ranging module is chosenAB(ii) a r may be a maximum value, a minimum value, an average value over a period of time, and the like of the distance between the first ranging module and the second ranging module, and in this embodiment, may be a minimum value.
Can be based on the linear distance l between the first ranging module and the second ranging moduleABChange of short time l'ABPresume the sleep state of the second subject, etc.; by calculating lABRelative relationship to r'ABThe size of (a) gives the interference probability a1And interference level beta1。
As shown in fig. 7, the pressure P of the second subject's arm and torso against the bladder is different; for example, since the pressure P of the trunk on the air bladder is larger than that of the upper limbs, it can be presumed that to some extent, the larger P, the closer the second object is to the first object, and the possibility of interference α1To a greater extent, interference degree beta1It is also relatively severe; for another example, when the second object has an action pressure similar to turning over and the like on the airbag and approaches the first object, the change value Δ P of the air pressure in the airbag is large, and if the action of turning over and the like on the airbag is finished, the change value Δ P is 0 or is relatively small. The interference probability α can thus be calculated from the pressure P of the limb or torso of the second object against the bladder and the change Δ P in the bladder due to the movement of the limb or torso2And interference severity degree beta2。
The S1032 may specifically be: synthesis of alpha1、α 2And beta1、β 2The interference probability a and the interference level β are evaluated. Alpha and beta can be represented by the formula1、α 2Or beta1、β 2Each assigned a respective coefficient and then summed or calculated by another formula, e.g. α ═ j · α1+k*α 2，β＝s*β 1+t*β 2(ii) a Wherein the coefficients j, k, s, t and the size and shape of the air bag areAnd off. For example, it may be desirable to have α ═ α1+α 2)/2，β＝(β 1+β 2)/2；
And when both alpha and beta are greater than the preset values, the air pressure regulating module is controlled to inflate the air bag, so that the inflated and expanded air bag can interfere the second object to be far away from the cushion.
After the balloon is inflated, the method may further comprise the steps of:
synthesis of alpha1、α 2And beta1、β 2Estimating the interference possibility alpha and the interference level beta, alpha and beta can be obtained by comparing alpha1、α 2Or beta1、β 2Each assigned a respective coefficient and then summed or calculated by another formula, e.g. α ═ j · α1+k*α 2，β＝s*β 1+t*β 2(ii) a Wherein the coefficients j, k, s, t are related to the size, shape, etc. of the air bag. For example, it may be desirable to have α ═ α1+α 2)/2，β＝(β 1+β 2)/2；
And when the alpha and the beta are both smaller than the preset value, controlling the air pressure adjusting module to deflate the air bag.
