Example 1

In this embodiment, as shown in fig. 1A, there is provided a mattress control method, which includes:

step 110, collecting the compression pressure values of pressure sensors in preset adjusting areas on a mattress, wherein the mattress is divided into a plurality of preset adjusting areas in advance, and a plurality of pressure sensors are arranged in each preset adjusting area.

In this embodiment, as shown in fig. 4, the mattress is uniformly divided into a plurality of areas, each area is a preset adjustment area, and a plurality of pressure sensors are disposed in each preset adjustment area and are used for detecting the pressure of a human body, when a user lies or sits on the mattress, the pressure is generated on the mattress, and each pressure sensor detects the pressure of the user on the mattress. It should be understood that the user's lying and sitting postures are different, and the pressure values detected by the pressure sensors are also different. In this embodiment, the pressure value detected by each pressure sensor is a pressure-receiving pressure value.

It should be noted that the areas and shapes of the preset adjusting areas may be different or equal. The division of the preset adjustment area may be divided according to user habits and may be divided into different shapes. In order to uniformly detect the pressure value, in one embodiment, as shown in fig. 4, the preset adjustment regions are identical in shape and equal in area. In one embodiment, each preset adjustment area is square in shape, and the areas of the preset adjustment areas are equal. In this embodiment, the mattress is divided into a plurality of preset adjustment areas of equal size. In other embodiments, the shape of the preset adjusting area may be a triangle, such as an equilateral triangle, or a regular hexagon or an octagon, which is not listed in this embodiment.

Step 120, calculating an average pressure value according to each of the pressure values of each of the preset adjustment areas.

In this embodiment, an average value of pressure values detected by each pressure sensor in a preset adjustment area is calculated, so as to obtain an average pressure value of the preset adjustment area.

In one embodiment, the average pressure value is an average of the pressure values detected by the pressure sensors of the single preset adjustment area; in one embodiment, the average pressure value is an average of the pressure values detected by the pressure sensors in all preset adjustment areas.

And 130, calculating the proportion of the pressure sensor with the pressure value larger than the average pressure value in the preset adjusting area, and determining the proportion as a high pressure proportion.

In this embodiment, the number of pressure sensors whose pressure values are greater than the average pressure value is first determined, the number of pressure sensors whose pressure values are greater than the average pressure value is divided by the total number of sensors in the preset adjustment area, so that the proportion of pressure sensors whose pressure values are greater than the average pressure value in the preset adjustment area is obtained, and the proportion is determined as a high pressure proportion.

And 140, adjusting the air pressure of the air bags of the corresponding preset adjusting areas according to the high-pressure ratio, wherein at least one air bag is arranged in each preset adjusting area.

In this embodiment, the high pressure ratio reflects the ratio of the pressure value of the pressure sensor in the preset adjustment area to be greater than the average pressure value, and reflects whether the pressure distribution is balanced, and the greater the high pressure ratio is, the greater the pressure received by the preset adjustment area is, so that the air pressure of the air bag in the preset adjustment area is adjusted accordingly. It should be noted that at least one air bag is disposed in each preset adjusting area, and in one embodiment, an air bag is disposed in each preset adjusting area, so that the air bags in the preset adjusting areas are individually adjusted according to the high pressure ratio of the preset adjusting areas. In one embodiment, a plurality of air bags are arranged in each preset adjusting area, and the position of each air bag corresponds to the position of the pressure sensor, so that the air pressure of the plurality of air bags in the preset adjusting areas can be adjusted simultaneously by arranging the plurality of air bags in the preset adjusting areas.

The air bag can be inflated through the air supply element such as the air pump, so that the air pressure in the air bag is increased, and the greater the air pressure in the air bag is, the better the supporting property of the air bag is. Therefore, through the high-pressure ratio of each preset adjusting area, the air bags of the areas with larger pressure can be inflated accurately, and the air bags of the areas with smaller pressure can be kept, so that the air bags are better adapted to the postures of users, and better support is provided for the users.

In the above embodiment, by detecting whether the pressure value of each pressure sensor in each preset adjusting area is greater than the average pressure value of the preset adjusting area, it is determined whether the preset adjusting area has uneven pressure, so that the air pressure of the air bag in the preset adjusting area is correspondingly adjusted, the user can lie more comfortably, automatic pressure adjustment is realized, the pressure adjustment is more suitable for the lying position and posture of the human body, and the pressure adjustment is more accurate. In addition, through carrying out gasbag inflation regulation to the great region of local pressure, can alleviate the local long-term pressurized of user when lying down, do not receive sufficient support and lead to ache, sweating, avoid the body surface moist.

In one embodiment, each preset adjusting area is divided into a plurality of collecting areas in advance, each collecting area is internally provided with a pressure sensor, and each collecting area is internally provided with a gas bag; the step of adjusting the air pressure of the air bag of the corresponding preset adjusting area according to the high pressure ratio comprises the following steps: detecting whether the high-voltage ratio of the preset adjusting area is in a preset ratio range or not; when the high-pressure ratio is in the preset ratio range, determining an acquisition area where a pressure sensor with a pressure value larger than the average pressure value is located as a reference area; and adjusting the air pressure of the air bags of the reference area and the acquisition area adjacent to the reference area.

In this embodiment, as shown in fig. 5, the preset adjusting area is divided into a plurality of collecting areas, and a pressure sensor and an air bag are disposed in each collecting area, so that when the air pressure of the air bag is adjusted, the air bag can be adjusted aiming at a single collecting area, local adjustment is realized, and further, the adjustment of the pressure is more accurate. When the high pressure ratio of the preset adjusting area is within the preset proportion range, the collecting area where the pressure sensor with the pressure value larger than the average pressure value is located is taken as a reference area, and the air pressure of the air bags of the collecting area adjacent to the reference area is adjusted, for example, as shown in fig. 5, the pressure value of the collecting area with the coordinates of (x, y) is larger than the average pressure value, and then the collecting area is taken as the reference area, and the air bags of the collecting area adjacent to the periphery of the reference area (x, y) are correspondingly adjusted, so that good support can be provided for users by correspondingly adjusting the air pressures of the air bags of the collecting areas with the larger pressure and the surrounding areas.

It should be understood that the shapes of the acquisition regions may be the same or different, and the areas may be equal or different. For example, the shape of each acquisition region may be triangular, such as an equilateral triangle, or regular hexagon or octagon, which is not shown in this embodiment.

In one embodiment, as shown in fig. 5, the preset adjusting area is uniformly divided into a plurality of collecting areas, and each collecting area is square in shape, so that pressure can be uniformly collected for the preset adjusting area, and air pressure of the air bag can be uniformly adjusted, so that more accurate pressure adjustment is realized.

In one embodiment, the relationship between the high pressure ratio of the preset adjustment region and the air pressure of the air bag is a direct proportional correlation function.

In one embodiment, the relationship between the high pressure ratio of each preset adjustment zone and the air pressure of the air bag is a direct proportional correlation function, i.e. the high pressure ratio of each preset adjustment zone is proportional to the air pressure of the air bag. The larger the high pressure ratio of the preset adjustment area, the more areas are exposed to a greater pressure than the average pressure, and the more air is correspondingly filled into the air bag, so that the air pressure of the air bag is greater, and better support is provided.

In this embodiment, the third air pressure is greater than the second air pressure, the second air pressure is greater than the first air pressure, the extremum of the two ends of the third ratio range is greater than the extremum of the two ends of the second ratio range, and the extremum of the two ends of the second ratio range is greater than the extremum of the two ends of the first ratio range.

As shown in fig. 6, the air pressure of the air bag is set to three stages, which are respectively an air bag comfort mode, an air bag decompression mode, and an air bag jack-up mode. The air bag pressure corresponding to the air bag comfort mode is first air pressure, the air bag pressure corresponding to the air bag decompression mode is second air pressure, and the air bag pressure corresponding to the air bag jacking mode is third air pressure. The three-gear air bag working mode corresponds to three ranges where the high pressure proportion is located. Thus, the larger the high-pressure ratio of the preset adjusting area is, the higher the air pressure of the corresponding air bag is, which is beneficial to good support of human body.

In one embodiment, as shown in FIG. 6, the first ratio range is less than or equal to 10%, the second ratio range is greater than 10%, and less than or equal to 30%, and the third ratio range is greater than 30%, e.g., the first gas pressure is 15kpa, the second gas pressure is 20kpa, and the third gas pressure is 20kpa. Therefore, the air pressure of the air bag can be regulated in three steps, so that the air bag is suitable for different pressures of users.

when the high-pressure ratio is in a first ratio range, determining an acquisition area where a pressure sensor with a pressure value larger than the average pressure value is located as a reference area; and adjusting the air pressure of the air bags of each acquisition area with the distance from the reference area within a first preset distance to be the first air pressure, and controlling the air bags of the reference area to be not operated. When the high-pressure ratio is in the first ratio range, the air bag enters a relieving mode, the air bag corresponds to the pressure points one by one in the mode aiming at the pressed relative balance area, the coordinates of the points exceeding Gi are assumed to be Gx and y coordinates, the G (x+/-2 and y+/-2) air bag is started at the moment, namely the air bag works in the range around the overload pressure point, and the air bag at the Gx and y points does not work.

When the high-pressure ratio is in the second ratio range, determining an acquisition area where the pressure sensor with the pressure value larger than the average pressure value is located as a reference area; and adjusting the air pressure of the air bags of each acquisition area with the distance from the reference area being within a second preset distance to be the second air pressure, and controlling the air bags of the reference area to be not operated. When the high pressure ratio is in the second ratio range, the air bag enters a decompression mode, the air bag corresponds to the pressure points one by one in the stressed relatively unbalanced area in the mode, the coordinates of the points exceeding Gi are assumed to be Gx and y coordinates at the moment, the G (x+/-1, y+/-1) air bag is started at the moment, namely the air bag works in the range around the overload pressure point, and the air bag at the Gx and y points does not work.

When the high-pressure ratio is in a third ratio range, determining an acquisition area where a pressure sensor with a pressure value larger than the average pressure value is located as a reference area; and adjusting the air pressure of the air bags of the reference area and each acquisition area with the distance from the reference area being within a third preset distance to be the third air pressure, and controlling the air bags of the reference area to be not operated. When the high-pressure ratio is in the third ratio range, the air bag enters a jacking mode, the mode corresponds to the pressure points one by one for the very unbalanced area under pressure, at the moment, the coordinates of the points exceeding Gi are assumed to be Gx and y coordinates, at the moment, the air bag of the square area on the upper, lower, left and right sides of the area where G (x, y) is positioned is started, the loaded square area is jacked up, the condition of relieving stress concentration is realized, and the air bag of the square area where the overload pressure point is positioned does not work; it should be noted that, when the area is overloaded by more than 30% of the air bags, it is indicated that there is a significant pressure concentration in the area, and at this time, when the area is mobilized, the air bags cannot relieve the pressure load and may cause a more concentrated pressure, so that the air bags mobilizing the peripheral area of the square area work to lift the peripheral area of the pressure concentration point, thereby relieving the load bearing condition of the area.

In this embodiment, the first distance is greater than the second distance, and the second distance is greater than the third distance.

In one embodiment, the mattress control method further comprises: collecting the surface humidity value of the humidity sensor in each preset adjusting area; and adjusting the ventilation quantity of the ventilation air channels of the corresponding preset adjusting areas according to the surface humidity value, wherein at least one ventilation air channel is arranged in each preset adjusting area.

In this embodiment, the humidity value detected by each humidity sensor is a surface humidity value. It should be understood that the two main reasons for the bedsores caused by the influence on the health of bedridden people are that the body part is pressed to cause qi and blood to be unsmooth, and the body surface is airtight to cause higher humidity. The fact that the body part is pressed to cause qi and blood unsmooth can be known through detecting the pressure, when the high pressure ratio of a certain preset adjusting area is large, the fact that the pressure of the area is large indicates that the body part of a user is pressed, and therefore the air pressure of an air bag of the area needs to be adjusted. Too much pressure or long-term compression can also lead to airtight body surface, high humidity and bedsores. Therefore, in order to solve this problem, in addition to adjusting the air pressure of the air bag to adjust the supporting force, it is also necessary to adjust the ventilation amount of the ventilation air path in combination with the humidity detection, so as to perform a good ventilation effect, so that the user locally dries.

In this embodiment, the ventilation air path also can become ventilation passageway, ventilation gas pocket, and this ventilation air path communicates with the fan, and the wind that the fan blown out can blow out from mattress surface through this ventilation air path to make the body surface of human body obtain ventilating, and keep dry and comfortable. In this embodiment, the ventilation amount of the ventilation air path indicates the magnitude of the wind blown out from the ventilation air path. The power of the fan is controlled, so that the air quantity of the ventilation air paths can be controlled, and in addition, each ventilation air path can be provided with a regulating valve for regulating the air quantity of the ventilation air paths. In order to reduce the cost, an adjusting valve can be configured for a plurality of ventilation air paths in the same preset adjusting area, the plurality of ventilation air paths in the same preset adjusting area are connected with the fan through a main passage, and the main passage is provided with the adjusting valve, so that the air quantity of the ventilation air paths in the preset adjusting area can be adjusted through one adjusting valve, each ventilation air path is not required to be configured with the adjusting valve, and the cost is effectively saved.

It should be understood that in this embodiment, the collected humidity is not the body surface humidity of the human body, and the body surface humidity referred to in this embodiment is accurately monitored by the superhydrophobic biosensor to accurately monitor the humidity and perspiration condition of the human body surface in each preset adjustment area.

In this embodiment, through the combination of the regulation of the air pressure of the air bag and the regulation of the ventilation amount of the ventilation air path, not only can the human body be better supported, but also the human body can be prevented from being partially pressed, the humidity caused by air impermeability is higher, and the bedsore is prevented from being caused.

In one embodiment, the preset adjusting area is divided into a plurality of collecting areas, a humidity sensor is arranged in each collecting area, and ventilation air paths are uniformly distributed in each collecting area. Like this, through the humidity transducer in the collection region that more closely distributes carries out humidity detection, can detect the humidity of human body surface more accurately, in addition, can also blow to the ventilation gas circuit in each collection region individual control collection region, more accurately bloies.

In one embodiment, the relationship between the surface humidity value and the ventilation volume of the ventilation air path is a direct proportional correlation function relationship.

In one embodiment, the relationship between the surface humidity value of each preset conditioning area and the ventilation amount of the air bag ventilation circuit is a direct proportional correlation function relationship, that is, the surface humidity value of each preset conditioning area is in direct proportion to the ventilation amount of the air bag ventilation circuit. The larger the surface humidity value is, the serious local compression of the user is indicated, the perspiration can not be quickly evaporated, and the higher the humidity is, therefore, the ventilation quantity of the ventilation air path is correspondingly increased, and the quick evaporation of the sweat and the body fluid on the surface of the human body is realized.

In this embodiment, as shown in fig. 6, the ventilation amount of the ventilation air path is set to three levels, namely, a low ventilation level, a middle ventilation level and a high ventilation level. Wherein, the low ventilation grade corresponds to the first air volume, the middle ventilation grade corresponds to the second air volume, and the high ventilation grade corresponds to the third air volume. The three-gear ventilation quantity corresponds to three ranges of the surface humidity value. Therefore, the larger the surface humidity value of the preset adjusting area is, the higher the ventilation quantity of the corresponding ventilation air channel is, which is favorable for quickly evaporating sweat and body fluid on the surface of the human body, so that the surface of the human body is kept dry and comfortable, and bedsores caused by long-term lying are avoided.

In one embodiment, as shown in fig. 6, the humidity value of the normal human body surface is R0, the first humidity range is less than or equal to R0, the second humidity range is greater than R0 and less than or equal to 2 times R0, and the third humidity range is 2 times R0, for example, the third air volume is greater than the second air volume, and the second air volume is greater than the first air volume. The extremum at both ends of the third humidity range is greater than the extremum at both ends of the second humidity range, which is greater than the extremum at both ends of the first humidity range. Like this, can carry out three to ventilation gas circuit's ventilation volume and keep off the regulation to adapt to different pressure and the humidity of user, effectively improve user's comfort level, avoid human part long-term pressurized, the humidity that airtight arouses is higher, avoid arousing the bedsore.

In one embodiment, the step of adjusting the air pressure of the air bag of the corresponding preset adjusting area according to the high pressure ratio includes: adjusting the air pressure of the air bag of the corresponding preset adjusting area according to the high-pressure ratio, and controlling the air pressure of the air bag to be maintained at the preset air pressure corresponding to the high-pressure ratio; the time length for maintaining and controlling the air bag at the preset air pressure is preset time, and the relation between the high pressure proportion and the preset time is a proportional correlation function relation. In one embodiment, the control air bag is deactivated after a preset time and is activated again after a preset rest time.

In this embodiment, the preset time corresponds to a range in which the high voltage ratio is located, each ratio range corresponds to a preset time, and the preset times may be equal or unequal. The preset air pressure is the air pressure of the air bag corresponding to each proportional range. For example, when the high pressure ratio is in the first ratio range, the preset air pressure is the first air pressure, for example, when the high pressure ratio is in the second ratio range, the preset air pressure is the second air pressure, for example, when the high pressure ratio is in the third ratio range, the preset air pressure is the third air pressure.

In this embodiment, according to the high pressure ratio, the air bag of the preset adjusting area is controlled to enter a working mode corresponding to the high pressure ratio, and the working mode is maintained for a preset time. As shown in fig. 6, when the high pressure ratio is less than 10%, the operation mode of the airbag controlling the preset adjustment region is the airbag relaxing mode, the airbag inflation pressure is 15kpa, and the preset time is maintained for 20 seconds. When the high pressure ratio is more than 10% and less than or equal to 30%, the operation mode of the air bag controlling the preset adjusting area is an air bag decompression mode, the air bag inflation pressure is 20kpa, and the preset time is maintained for 30 seconds.

In one embodiment, the air pressure of the air bag of the corresponding preset adjusting area is adjusted according to the high-pressure ratio, and the air pressure of the air bag is controlled to be maintained at the preset air pressure corresponding to the high-pressure ratio; adjusting the ventilation quantity of the ventilation air circuit of the corresponding preset adjusting area according to the surface humidity value, and controlling the ventilation quantity of the ventilation air circuit to be maintained at the preset ventilation quantity corresponding to the surface humidity value; the air bag is controlled to be at preset air pressure and the time length for maintaining the ventilation air path to be at preset ventilation amount is maintained to be at preset time, and the relation between the high-pressure proportion and the preset time is a direct proportion correlation function relation. In one embodiment, the air bag and the ventilation circuit are controlled to stop working after a preset time, and the working is started again after a preset rest time.

In this embodiment, according to the high pressure ratio, the air bag of the preset adjusting area is controlled to enter a working mode corresponding to the high pressure ratio, the ventilation air path is controlled to enter a working mode corresponding to the surface humidity value according to the surface humidity value, and the air bag and the ventilation air path are maintained to reach preset time in the respective working modes. That is, the preset time is determined according to the high pressure ratio, and when the high pressure ratio is determined, the air bag and the ventilation air path enter the corresponding operation modes and maintain the preset time. As shown in figure 6 of the drawings,

When the high-pressure ratio is less than 10%, and the surface humidity value is in the first humidity range and is less than or equal to R0, the ventilation air passage is controlled to enter a ventilation low gear, and the ventilation air passage is controlled to enter a working mode of the ventilation low gear for 20 seconds. When the high-pressure ratio is more than 10% and less than or equal to 30%, and the surface humidity value is in the second humidity range and is more than R0 and less than or equal to 2R0, the ventilation air passage is controlled to enter a ventilation middle gear, and the working mode of the ventilation air passage entering the ventilation middle gear is maintained for a preset time of 30 seconds.

Example two

In this embodiment, as shown in fig. 1B, a mattress control method is provided, including:

step 161, collecting the pressure values of the pressure sensors in each preset adjusting area on the mattress.

Step 162, calculating an average pressure value according to each of the pressure values of each of the preset adjustment areas.

And 163, calculating the proportion of the pressure sensor with the pressure value larger than the average pressure value in the preset adjusting area, and determining the proportion as a high pressure proportion.

And step 164, collecting the surface humidity value of the humidity sensor in each preset adjusting area.

And step 165, adjusting the air pressure of the air bag of the corresponding preset adjusting area according to the high-pressure ratio, and adjusting the ventilation quantity of the ventilation air path of the corresponding preset adjusting area according to the surface humidity value.

It should be understood that the two main reasons for the bedsores caused by the influence on the health of bedridden people are that the body part is pressed to cause qi and blood to be unsmooth, and the body surface is airtight to cause higher humidity. The fact that the body part is pressed to cause qi and blood unsmooth can be known through detecting the pressure, when the high pressure ratio of a certain preset adjusting area is large, the fact that the pressure of the area is large indicates that the body part of a user is pressed, and therefore the air pressure of an air bag of the area needs to be adjusted. Too much pressure or long-term compression can also lead to airtight body surface, high humidity and bedsores. Therefore, in order to solve this problem, in addition to adjusting the air pressure of the air bag to adjust the supporting force, it is also necessary to adjust the ventilation amount of the ventilation air path in combination with the humidity detection, so as to perform a good ventilation effect, so that the user locally dries. Therefore, in this embodiment, not only the air pressure of the air bag is adjusted according to the high-pressure proportion, but also the ventilation amount of the ventilation air path is adjusted according to the surface humidity value, so as to adapt to different postures of the user, avoid the user lying for a long time to cause local compression, improve the ventilation efficiency of the body surface, avoid the body surface to be airtight and cause higher humidity, and avoid bedsores. The pressure regulation and the ventilation quantity regulation of the air bag are combined, so that discomfort of a user can be effectively avoided.

It should be noted that, in this embodiment, the layout of the mattress, the control logic of the air bag, and the control logic of the ventilation amount of the ventilation air path may all adopt the same manner as in the first embodiment, and in this embodiment, no redundant description is made.

Example III

In this embodiment, the intelligent mattress needs to be equipped with the following functional modules:

1. the intelligent mattress is provided with a super-hydrophobic biosensor, accurately monitors the humidity and perspiration conditions of the surface of the human body, and presumes that the actual measured humidity condition of the surface of the human body is R;

2. the intelligent mattress is provided with a ventilation system, and can provide different modes of active ventilation operation according to different wet and dry states of the body surface of a user, the ventilation system is protected by related patents, and the ventilation scheme structure protection is not carried out, so that detailed description is omitted;

3. the intelligent mattress provides an air bag device, the intelligent mattress provides a pressure sensor, a plurality of air bags and a plurality of pressure sensors are densely distributed in the mattress, one air bag corresponds to one pressure sensor, and the air bag mode is divided into a relieving mode, a decompression mode and a jacking mode, and different application scenes are different, and are described in detail below.

4. The mat was divided into areas of different square areas, as shown in fig. 4, including area 1.2.3. The inner square area is correspondingly provided with a super-hydrophobic biosensor for accurately monitoring the humidity and perspiration of the surface of the human body, and the ventilation air channels are correspondingly arranged in the corresponding square areas to perform ventilation operation according to the body surface dry and wet conditions, wherein the ventilation air channels in the square areas can be independently controlled.

The pressure sensors are arranged in the areas of each block, and can acquire pressure values of the device, wherein in the i pressure area, the average value of the pressure of each pressure point is as follows:

G _i ＝(G _1，1 +G _1,2 +...G _n,m )/(n*m)

the information of the G point at the different positions can be referred to in fig. 5 as the position and relative coordinate relationship, wherein the different modes of the balloon action are related to the positions of the different pressures.

Based on the above modules, in this embodiment, please refer to fig. 6, the control logic of the intelligent mattress for the long-term bedridden person is as follows:

a) Opening an intelligent mattress;

b) Dividing the cushion layer into a plurality of square areas;

it can be assumed, but is not limited to, setting the mat length to 2 meters and width to 1.2 meters for application to a single person, divided into several square areas, 1.2.3.

c) Calculating and obtaining average pressure values Gi in different areas;

the pressure sensors are arranged on the surface of the mattress, and a plurality of pressure sensors, namely pressure points are contained in different areas, wherein the average value of the pressure of each pressure point is Gi in the pressure area, and the fifth point can be seen in particular;

d) The system acquires the number of the duty ratios exceeding the Gi pressure values in different square areas;

the number of location points exceeding the Gi pressure value/total number in square area is 100%

When the point exceeding Gi in the area of a single square is less than or equal to 10%, the stress in the area is relatively balanced, the difference between the maximum point and the minimum point is not large, and the human body feeling is relatively relaxed;

when the point exceeding Gi in the area of a single square is more than 10% and less than or equal to 30%, the stress in the area is relatively unbalanced, the difference between the maximum point and the minimum point is large, and the human body feel is not relaxed;

when the point exceeding Gi in the area of a single square is more than 30%, the stress in the area is very unbalanced, the difference between the maximum point and the minimum point is very large, and the human body feel is very uncomfortable;

e) After the system judges the pressure bearing condition of the local area of the human body, judging the body surface humidity value;

as is well known, the health of bedridden people is affected, the most main two points of bedsore are that the body part is pressed to cause qi and blood to be unsmooth, the body surface is airtight to cause higher humidity, after judging the body part to bear pressure in the step d, the body surface humidity is judged next, the air humidity is required to be explained here and is not the human body surface humidity, the body surface humidity is pointed here, through super-hydrophobic biosensor, the humidity and perspiration condition of the human body surface in each square area are accurately monitored, the actual measurement of the human body surface is assumed to be R, the humidity value of the normal human body surface is RO:

When the humidity value R of the human body is less than or equal to RO, the human body is in a normal humidity range at the moment, and only a low-grade ventilation mode is started, so that the ventilation and drying requirements of the basic human body are maintained;

when the humidity value RO of the human body is less than R and less than or equal to 2RO, the human body is in a higher humidity state, a middle-grade ventilation mode is started, and sweat on the surface of the human body is air-dried and volatilized;

when the humidity value R of the human body is more than 2RO, the human body is in a high humidity state, a high-grade ventilation mode is started, and sweat on the surface of the human body is air-dried and volatilized;

f) After the surface humidity is judged, different countermeasures and judgment are made by the system according to different humidity values and different bearing conditions, and besides the ventilation scheme, the system also comprises the following steps:

when the point exceeding Gi in the area of a single square is less than or equal to 10%, the stress in the area is relatively balanced, the difference between the maximum point and the minimum point is not large, and the human body feeling is relatively relaxed; -airbag deployment release mode:

the mode aims at a pressed relative balance area, the air bags and the pressure points are in one-to-one correspondence, at the moment, the coordinates of the points exceeding Gi are assumed to be Gx and y coordinates, at the moment, the G (x+/-2, y+/-2) air bags are started, namely the air bags in the range around the overload pressure point work, and the Gx and y point air bags do not work;

Because the stress is relatively balanced, the inflation pressure of the air bag is set to 15KPa, the inflation is carried out for 20S and the rest is carried out for 10S (the specific time is defined herein, if the protection scope of the patent is reduced, letters can be set to refer to the specific number);

when the point exceeding Gi in the area of a single square is more than 10% and less than or equal to 30%, the stress in the area is relatively unbalanced, the difference between the maximum point and the minimum point is large, and the human body feel is not relaxed; airbag opening decompression mode:

the mode aims at a relatively unbalanced area under pressure, the air bags and the pressure points are in one-to-one correspondence, at the moment, the coordinates of the points exceeding Gi are assumed to be Gx and y coordinates, at the moment, the G (x+/-1, y+/-1) air bags are started, namely the air bags in the range around the overload pressure point work, and the Gx and y air bags do not work;

because the stress is relatively unbalanced, the inflation pressure of the air bag is sufficiently set to 20KPa, 30S is inflated and 10S is at rest (letters can be set to refer to specific numbers if the specific time is defined herein to reduce the protection range);

it should be noted that, when the local load bearing condition is greater than 10% and less than or equal to 30%, the load bearing condition is more concentrated than the previous condition, so when the air bag working area is selected, the more concentrated air bag working area is selected to relieve the condition of pressure concentration;

When the point exceeding Gi in the area of a single square is more than 30%, the stress in the area is very unbalanced, the difference between the maximum point and the minimum point is very large, and the human body feel is very uncomfortable; -air bag opening jack-up mode:

aiming at a very unbalanced area under pressure, the air bags and the pressure points are in one-to-one correspondence, at the moment, the coordinates of the points exceeding Gi are assumed to be Gx and y coordinates, at the moment, the air bags of square areas on the upper, lower, left and right sides of the area where G (x, y) is positioned are opened, the area of the loaded square is lifted, the condition of relieving stress concentration is realized, and the air bags of the square areas where the overload pressure points are positioned do not work;

it should be noted that when the area is overloaded by more than 30% of the air bags, it is indicated that the area has obvious pressure concentration, and at this time, when the area is mobilized, the air bags cannot slow down the pressure loading and may cause more concentrated pressure, so that the air bags mobilizing the peripheral area of the square area work to lift the peripheral area of the pressure concentration point, so as to slow down the bearing condition of the area;

g) Finally, the working time T0/T1/T2 refers to the time length of defining the working mode to be started according to different loading conditions and surface humidity conditions, and T0 < T1 < T2 are defined.

It should be understood that, although the steps in the flowchart of fig. 1 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. For example, the pressure acquisition and the humidity acquisition can be performed simultaneously, or the humidity acquisition can be performed first and then the pressure acquisition can be performed. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 1 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor do the order in which the sub-steps or stages are performed necessarily performed in sequence, but may be performed alternately or alternately with at least a portion of other steps or sub-steps of other steps.
