Moreover, wearing some wearable devices during sleep may actually hinder sleep and have a certain impact on the comfort of the sleep process. Therefore, in some existing products, the detection device of sleep quality is arranged on the mattress or around the mattress.

For example, the Chinese patent document with the publication number CN 104101383B discloses a smart mattress based on a fiber grating sensor.

However, the main problems in this patent are as follows: First, people have different physiques, so there are differences in individual body temperature during sleep. Although some people have high body temperature, they are not "hot" in nature. Measuring data to adjust temperature cannot achieve good results; second, the arrangement of sensors is not optimized according to the characteristics of the corresponding sensors, resulting in a large number of installed sensors, high cost and low accuracy of measurement results.

Therefore, the present invention further judges the real reason affecting the sleep quality of the user by setting the ISFET-based chemical sensor to measure the concentration of sweat ions.

The setting of the leakage hole can prevent the user's skin surface and the upper surface of the second sensor from forming a closed area, causing the skin in the closed area to have dermatitis, prickly heat or other skin problems due to airtightness. In addition, the skin located in the closed area It is also possible that the user sweats abnormally without being hot, which affects the accuracy of the measurement results. The upper opening of the leak hole is small and the lower opening is large to prevent sweat from blocking the leak hole. The first opening of the ventilation hole is arranged at the upper end of the vertical groove, and the lowest point of the first opening is higher than the lowest point of the lower convex part so that the first opening is hidden in the groove between the lower convex part and the side wall , to prevent the liquid flowing down the upper edge from blocking the first opening, and the second opening of the vent hole is arranged at the connection between the lower surface of the recessed part and the inner side of the side wall of the second sensor. With a downward inclination, the liquid flowing down from the leakage hole will not flow back to the second opening to block the second opening, so the vent hole has good anti-blocking performance. Since the herringbone air hole opens downward, it is not easy to accumulate a large amount of liquid, which can further improve the air permeability. The measuring surface of the second sensor is set on the upper edge and is depressed toward the center in the center of the depression, and the upper surface of the depression is provided with a leaky hole with a small upper opening and a large lower opening in the central area of the depression, which helps to prevent sweat from always accumulating on the measuring surface and cause the second stage in the later stage. The second sensor measures non-real-time measurement data and affects the accuracy of measurement results.

According to a preferred embodiment, the connection wires used to communicate with the second sensors are set in such a way that the wiring length between two adjacent second sensors is greater than the distance between the two second sensors, wherein the The connection line is arranged in the gap between the middle layer and the bottom layer in a movable manner relative to the middle layer or the bottom layer and is connected to the corresponding second sensor through a detachable electrical connector with an extension line, Wherein, the bottom layer is provided with an anti-rotation flange matched with the corresponding vertical groove to prevent the rotation of the second sensor so that the electrical connector arranged in a vertical groove can drive the corresponding extension wire The gap between the vertical groove and the installation channel moves up and down with the second sensor. The wiring length between two adjacent second sensors is greater than the distance between the two second sensors, allowing relative movement of the two second sensors, reducing the probability of the electrical connector being disconnected due to pulling force, and improving the The reliability of smart mattresses with sweat sensors.

According to a preferred embodiment, the hole wall of the leakage hole is also provided with at least one drainage part whose upper part is flush with the upper surface of the concave part and whose lower part exceeds the lower surface of the concave part, and the lower part of the drainage part is suspended with a loose and porous evaporation part , wherein the minimum lateral dimension of the evaporation portion is greater than the maximum lateral dimension of the lower opening of the leakage hole and the projection line of the outer contour of the evaporation portion in the projection plane facing the ground surrounds the projection line of the lower opening of the leakage hole In, wherein, the lower part of the drainage part is connected to the upper edge of the evaporation part and the first included angle between the part of the drainage part beyond the lower surface of the recessed part and the horizontal plane is smaller than that of the drainage part that does not exceed the A second included angle between a portion of the lower surface of the recessed portion and the horizontal plane. The setting of the drainage part helps to further prevent the liquid from clogging the leakage hole and affecting the accuracy of the measurement result and the gas permeability of the second sensor. At the same time, the lower part of the drainage port is connected with a loose and porous evaporation part to quickly evaporate the liquid, especially the sweat, and also prevent the sweat from directly dripping onto the mattress body, which is not easy to clean and cause corrosion to the mattress body. The evaporated water vapor can be discharged through the air holes and/or air holes and escape to the outside through the gaps in the surface layer or the gap between the middle layer and the bottom layer.

According to a preferred embodiment, the smart mattress with a sweat sensor further includes a device integrated in the housing of the second sensor or arranged adjacent to the second sensor to correct the measurement result of the second sensor A temperature sensor, wherein when the temperature sensor is integrated in the housing of the second sensor, the measurement point of the temperature sensor is set within the upper edge. There is a linear relationship between the sensing element temperature of an ISFET and its output. Therefore, setting the temperature sensor at the same time helps to correct the measurement result of the second sensor to improve the accuracy of the second data. In addition, the temperature sensor can also be used to directly respond to the body temperature of the user so as to comprehensively analyze the actual situation of the user. The measurement point of the temperature sensor is set within the upper edge so that the measurement point directly contacts the skin to improve the accuracy of temperature measurement.

According to a preferred embodiment, the intelligent unit includes a data storage module, an analysis module and an execution module, wherein the analysis module monitors a plurality of the first data and counts the number of times the maximum rate of change exceeds the first threshold to obtain The first comparison result representing the frequency, and when the first comparison result exceeds a third threshold, selectively open and close part of the second sensor to collect second data according to a predetermined method, and perform the second data exceeding the second threshold The second comparison result is obtained through analysis, and the analysis module is further configured to send the first comparison result and the second comparison result to the execution module; the execution module sends the first comparison result and the The second comparison result is compared with the first reference value and the second reference value stored in the data storage module to obtain a corresponding preset control scheme and control one or more external devices based on the preset control scheme. The first comparison result can reflect the user's actions on the smart mattress with sweat sensor, such as turning over, swinging the arm or moving the legs and feet, etc., alone, it can feedback that the user may be restless or the user feels that the heat is adjusting the posture cooling, but the specific reason is not clear. The first comparison result combined with the second comparison result measured by contact with the user's body can further analyze the reasons for the user's first comparison result, thereby improving the user's sleep quality by controlling corresponding types of external devices. Preferably, since the second sensors are set to be in contact with the user's body to measure the second data, selectively energizing some of the second sensors when needed can reduce potential safety hazards.

According to a preferred embodiment, the analysis module collects the second data according to the following predetermined method and analyzes it to obtain the second comparison result: when the first comparison result exceeds the third threshold, the analysis module And when the current time is not in the analysis period, a reference time mark is set and an analysis period of a second preset duration is set with the time of the reference time mark as a reference point, wherein the analysis module is at the second preset time monitor the first data during the long analysis period, and set an intermediate time mark after the maximum rate of change exceeds the first threshold and then falls back to the first threshold for a first preset period of time until the The analysis period of the second preset duration ends; the analysis module selectively activates the second sensor in the center of gravity area or the second sensor in the non-center of gravity area according to the reference time mark or the intermediate time mark to collect the second data; when the analysis module does not collect the second data exceeding the second threshold within the analysis period of the second preset time length, it stops restarting the second data within the analysis period of the second preset time length Two sensors; when the analysis module collects at least one second data exceeding a second threshold within the analysis period, the analysis module analyzes the second data and obtains a second comparison result. Since the second sensor is configured to be in contact with the user's body to measure the second data, selectively energizing some of the second sensors when needed can reduce potential safety hazards. Because the probability that the user may be in the center of gravity area is greater than the probability that the user may be in the non-center of gravity area, first only turning on the second sensor in the center of gravity area can save energy, reduce the frequency of use of the second sensor to increase its life cycle, and reduce the long-term use of the second sensor Potential safety hazards that may result. However, since there may be more than one person on the mattress, there may be two or more. Therefore, the center of gravity area is only the position where the user exists in an ideal state. If the second data is not measured after turning on the second sensor in the center of gravity area, it is possible that the user is not actually in the center of gravity area or the measurement condition of the contact part of the user's body and the second sensor does not meet the measurement standard, for example: no sweat , unstable contact or no direct contact with the body, etc. In addition to the above reasons, during the alternation period, the user's body may also have fine-tuning, causing one or more second sensors in the center of gravity area or non-center of gravity area to measure the second data, so at this time the switch is alternately in the The second sensor in the center of gravity area and the second sensor in the non-center of gravity area help to obtain the second data, and can also save energy.

According to a preferred embodiment, the second sensor is started and stopped in the following way: the analysis module first calculates the center of gravity of the target to be measured according to a plurality of the first data at the reference time mark or the intermediate time mark region and alternately switch the second sensor in the center of gravity region and the second sensor in the non-center of gravity region according to a preset number of times at a time interval of a third preset duration; when the analysis module is in the When the second data exceeding the second threshold is collected within the preset number of times, the analysis module stops restarting the second sensor within the analysis period of the second preset time length, and when the analysis module When the second data exceeding the second threshold is not collected within the number of times, the analysis module repeats the above process when the next intermediate time mark is set and the analysis period is not over. When no second data exceeding the second threshold is collected at the end of the period, the analysis module calls the smallest second comparison result stored in the data storage module within the preset period. For the second data, since the ion concentration of sweat less than the second threshold indicates that the user's physical condition is good and the body surface is slightly hot, it is not necessary to turn on the external device as soon as there is sweat. Therefore, setting the second threshold to filter out the available second data helps to turn on the external device according to the actual situation, and prevent the life of the external device from being reduced and unnecessary noise caused by frequent startup of the external device. Measurements that fall outside the physiological range may indicate an accumulation of cleaning product residue on clothing, such as ionic concentrations in sweat, such as sodium or potassium concentrations greater than 1.1 times the physiological maximum ion concentration indicate residue accumulation, in which case It indicates that the collected second data is not available, therefore, setting the second threshold helps to screen out the available second data and ensure the accuracy of the measurement.

According to a preferred embodiment, the execution module obtains the corresponding preset control scheme and controls the corresponding external device in the following manner: when the first comparison result is greater than or equal to the first reference value and the second comparison When the result is greater than the second reference value, the first preset control scheme is obtained, and the execution module controls at least one first external device for hypnosis and at least one second external device for cooling the user according to the first preset control scheme. External equipment; when the first comparison result is greater than or equal to the first reference value and the second comparison result is less than the second reference value, a second preset control scheme is obtained, and the execution module controls the user according to the second preset control scheme At least one first external device for hypnosis; when the first comparison result is less than the first reference value and the second comparison result is greater than or equal to the second reference value, the third preset control scheme is obtained, and the execution module according to the first Three preset control schemes control at least one second external device used to cool the user; when the first comparison result is less than the first reference value and the second comparison result is less than the second reference value, the fourth preset control is obtained According to the fourth preset control scheme, the executive module controls not to turn on the first external device and the second external device; wherein, the first external device has a sound that can play hypnotic music and/or can release aromatherapy In the electronic sleep aid aromatherapy, the second external device is an air conditioner and/or a fan. By analyzing the reasons that affect the user's sleep quality and using the preset scheme to control the external device can significantly improve the user's sleep quality.

detailed description

A detailed description will be given below in conjunction with the accompanying drawings.

1, 2, 3, 4 and 5, the intelligent mattress with sweat sensor of the present invention is shown below.

Example 1

According to a preferred embodiment, an intelligent mattress with a sweat sensor includes a mattress body 1 and an intelligent system 2 . The intelligent system 2 includes: an intelligent unit 21, at least four first sensors 22 capable of supporting the mattress body 1 and obtaining first data representing the force status of the corresponding supporting point, and in a manner capable of directly contacting the target to be measured. A plurality of second sensors 23 are provided. The second sensor 23 is an ISFET-based chemical sensor for measuring second data representative of sweat ion concentration. The second sensor 23 is arranged on the mattress body 1 along the length direction from the first side A to the second side B of the mattress body 1 according to the trend that the density first decreases and then increases. The density of the second sensors 23 in the middle region between the first side A and the second side B is the smallest and the density of the second sensors 23 in the middle region between the first side A and the second side B decreases to a first degree greater than the second side B to the middle. The density of the second sensor 23 of the region is reduced to a second degree. The intelligent system 2 controls one or more external devices by obtaining a corresponding preset control scheme after analyzing the first data and the second data.

According to a preferred embodiment, the first sensor 22 is a pressure sensor.

According to a preferred embodiment, the first sensor 22 is a displacement sensor.

Preferably, by optimizing the arrangement of the second sensors, the purpose of measurement can be achieved with as few sensors as possible, which can reduce manufacturing and purchase costs and improve resource utilization. Moreover, the sensor is an electronic product, although it can improve safety by protecting the circuit and reduce the probability of accidents such as leakage or short circuit. However, the densely arranged second sensors will not only cause psychological stress to users, but also affect sleep quality. Moreover, the greater the number of second sensors, the higher their potential safety risks. Therefore, by optimizing the arrangement of the second sensors, the safety can be further improved, the psychological pressure of the user can be reduced, and the negative impact of the densely arranged second sensors on the user's sleep quality can be reduced psychologically. Because when sleeping, especially in summer, most people are used to sleeping half naked only in shorts or underwear, or wearing underwear and shorts, or shorts and short sleeves and so on. Among them, the middle part of the body is more likely to be covered, and the second sensor needs to be in contact with the user's skin to accurately measure the second data. Therefore, the area around the middle of the body should have as few second sensors as possible. The back and feet are most likely to be exposed during sleep. In order to improve the measurement efficiency, more second sensors should be installed on the back and legs. Therefore, the second sensor 23 is arranged on the mattress body 1 along the length direction from the first side A to the second side B of the mattress body 1 according to a trend that the density first decreases and then increases. Preferably, when each user is sleeping, due to individual differences and different wearing habits, the areas of contact between the upper body and the lower body of the mattress body 1 are different. Therefore, it is not necessary to set the density of the second sensor symmetrically. Wherein, the difference between the first degree and the second degree fully considers the individual differences and wearing habits of each user, and further reduces the number of arrangement of the second sensors. For example, if the first user is used to wearing only shorts when sleeping, his upper body and legs will be in contact with the mattress body 1 when sleeping. However, since the upper body has a large contact area with the mattress body 1, it is easier to measure the second data, so more sensors should be arranged near the upper body of the first user. Therefore, the first user can sleep with the pillow arranged near the first side A in this case. For another example, if the second user is used to wearing short sleeves and underpants while sleeping, the main parts that contact the mattress body 1 when sleeping are the legs and hands, but the area where the legs contact the mattress body 1 is larger and more It is easy to measure the second data, and more sensors should be arranged near the legs of the second user. Therefore, the second user can sleep with the pillow arranged near the second side B in this case. For another example, although the third user only wears shorts when sleeping, according to his experience, his legs and feet sweat more than his upper body when the ambient temperature is high. Therefore, in this case, the first side A may be arranged away from the third user's head. In this case the third user can arrange the pillow near the second side B to sleep. Preferably, the surface layer 11 is detachable and washable.

Preferably, the ISFET is an ion selective field effect transistor. Preferably, the ISFET-based chemical sensor may comprise an ISFET and a reference electrode, wherein the ISFET and the reference electrode are arranged to be in direct contact with the user's skin. The reference electrode can be selected from Ag/AgCl electrodes, Ag/AgCl plastic composite electrodes, Ag/AgCl gel electrodes, Ag/AgCl electrodes coated with permeable membranes, polypyrrole electrodes and poly-3,4-ethylenediene electrodes. A group consisting of oxythiophene electrodes. The reference electrode may be an Ag/AgCl electrode coated with a permeable membrane and permeated with chloride ions. The reference electrode can be a carbon paste electrode mixed with a mediator such as ferrocene or Prussian blue. The reference electrode may be a noble metal reference electrode and/or a pseudo-reference electrode, eg the noble metal may be gold or platinum. The permeable membrane may be selected from polyvinyl butyral, polyhydroxyethyl methacrylate, perfluorosulfonic acid polymers, and combinations thereof. Preferably, a portion of the ISFET is located on a protrusion of the housing arranged to enhance skin contact with the portion. Preferably, the ion concentration is primarily of the group consisting of sodium ion concentration and potassium ion concentration. Preferably, in addition to the chemical sensor, the smart mattress with sweat sensor of the present invention also includes at least one additional second chemical sensor based on ISFET, wherein the ISFET of the second chemical sensor is configured to monitor A property of a liquid other than its ion concentration. For example, pH. The pH value can reflect the user's skin health index, for example, a pH value greater than or equal to 6 is an index of skin irritation or poor skin health. Users can prevent skin health from deteriorating by changing cosmetics or adjusting diet based on the pH information measured at night. Alternatively, the intelligent mattress with sweat sensor of the present invention uploads the pH value information to cloud storage, and the data stored on the cloud can be viewed by professionals such as doctors or skin care personnel in beauty salons, so as to provide users with reasonable suggestions.

Preferably, the slope of the upper surface of the recessed portion 232 is 5%˜12%. If the slope of the upper surface of the recessed portion 232 is too large, the sweat will flow out of the leakage hole too fast, so that the corresponding second sensor 23 has no time to measure the corresponding second data. If the slope is set too small, the sweat beads will always be adsorbed on the measurement surface, which will affect the accuracy of the measurement. It has been found through experiments that a slope of 5% to 12% can prevent sweat from leaking from the leakage hole too quickly and will not cause sweat beads to absorb.

The bottom layer 12 is provided with an anti-rotation flange 122 matched with the corresponding vertical groove 236 to prevent the rotation of the second sensor 23 so that the electrical connector 42 located in a vertical groove 236 can drive the corresponding extension. The wire 41 moves up and down with the second sensor 23 in the gap between the vertical groove 236 and the installation channel. Preferably, the electrical connector 42 and the anti-rotation flange 122 are disposed in different vertical grooves to prevent the anti-rotation flange 122 from obstructing the movement of the extension wire 41 . Preferably, the diameter of the connection line 4 or the extension line 41 is smaller than the height of the gap between the middle layer 13 and the bottom layer 12 so that the connection line 4 or the extension line 41 can move freely in the gap.

According to a preferred embodiment, the smart mattress with sweat sensor further includes a temperature sensor 24 integrated in the housing of the second sensor 23 or disposed adjacent to the second sensor 23 to correct the measurement result of the second sensor 23 . When the temperature sensor 24 is integrated in the housing of the second sensor 23 , the measurement point of the temperature sensor 24 is located within the upper edge 231 . Preferably, the temperature sensor 24 is paired with the second sensor 23 so that when the ion concentration data is measured, the temperature during the ion concentration measurement is simultaneously recorded and used to correct the influence of temperature on the ion concentration data determined by the ISFET. Alternatively, the temperature sensor 24 may be used to measure the user's skin surface temperature as a physiological indicator. Preferably, instead of temperature correction, a heating element can also be integrated within the second sensor to keep the ISFET at a constant temperature, eg body temperature or above, but within the comfort limits of the skin.

According to a preferred embodiment, the intelligent unit 21 includes a data storage module 211 , an analysis module 212 and an execution module 213 . The analysis module 212 monitors a plurality of first data and counts the number of times the maximum rate of change exceeds the first threshold to obtain a first comparison result representing the frequency, and selectively activates according to a predetermined method when the first comparison result exceeds the third threshold. The second sensor 23 of the closing part collects second data and analyzes the second data exceeding the second threshold to obtain a second comparison result, and the analysis module 212 is also used to send the first comparison result and the second comparison result to the execution module 213. The execution module 213 compares the first comparison result and the second comparison result with the first reference value and the second reference value stored in the data storage module 211 to obtain a corresponding preset control scheme and control one or more control schemes based on the preset control scheme. external device. Preferably, experiments have shown that the first threshold value of 2% to 6% can filter out slight changes in the first data caused by the user's head tilting or slight movement of hands and feet. Such slight changes are unavoidable when people sleep. It cannot feedback the user's anxiety, anxiety or subconscious feeling of heat. At the same time, exceeding the first threshold means that the user has turned over or moved his hands and feet with a large movement, and at this time, it needs to be recorded in order to obtain the first comparison result. The first frequency or the first comparison result can reflect the frequency at which the user makes an action exceeding the first threshold on the smart mattress with a sweat sensor, and can be compared with smart bracelets or watches when the above-mentioned slight changes are excluded. Wearable devices better reflect the actual situation of the user. Preferably, the external devices mentioned in the present invention are all existing products. These external devices can be a single device such as an air conditioner, a fan, a stereo with hypnotic music stored on it, or an electronic sleep aid aromatherapy. The present invention can control these external devices uniformly or individually by controlling the power supply of the sockets of these external devices and/or the intelligent gateway of smart home and smart home appliances. For example, the use of external devices such as electronic sleep aid aromatherapy with few functions does not require too many settings, and only needs to be connected to the power supply. Therefore, when controlling this type of product, it can be plugged into a power strip that can be controlled by the intelligent unit 21, and the power supply of the power strip can be switched on and off according to the actual situation of the user to control Start and stop of electronic sleep aid aromatherapy. For external devices such as air conditioners that require multiple settings such as temperature, wind direction, wind speed, and ventilation during use, they can be connected to the smart gateway through the first dedicated controller of the air conditioner, and the sweat sensor The smart mattress is connected to the smart gateway through the second dedicated controller of the smart mattress with sweat sensor, and the smart mattress with sweat sensor can control its temperature, wind direction, wind speed and ventilation through a preset control scheme. and other settings and controls to achieve the purpose of intelligent control. When the smart mattress with sweat sensor detects that the user has not turned over for a long time and other large movements, it can also control the wind direction to avoid the user's position based on the measured user's position to prevent the user from catching a cold. Preferably, the smart mattress with a sweat sensor can also continuously learn and improve the preset control scheme to optimize the time to turn on each external device, the temperature set by the air conditioner, the wind direction or wind speed, etc., and finally achieve cost and resource savings. To improve the user's sleep quality. For example, a smart mattress with a sweat sensor increases the set temperature of the air conditioner by one degree every 15 minutes after reaching the preset target temperature for 30 minutes during a two-hour analysis period, and then monitors the temperature for the 15 minutes. Whether the user has a certain number of large actions. When a certain number of large movements are detected, the temperature of the air conditioner is lowered by one degree and maintained at this temperature during the analysis period, and then the target temperature in the corresponding preset control scheme is modified to this temperature. For the second data, since the ion concentration of sweat less than the second threshold indicates that the user's physical condition is good and the body surface is slightly hot, it is not necessary to turn on the external device as soon as there is sweat. Therefore, setting the second threshold to filter out the available second data helps to turn on the external device according to the actual situation, and prevent the life of the external device from being reduced and unnecessary noise caused by frequent startup of the external device. In addition, ion concentrations in sweat that fall outside the physiological range may indicate accumulation of cleaning product residue on clothing, for example sodium ion concentrations or potassium ion concentrations greater than 1.1 times the physiological maximum ion concentration indicate residue accumulation, which is the case in humans The impossible level of sweat ion concentration indicates that the collected second data is not available. Therefore, preferably, the present invention can also selectively open and close part of the second data according to a predetermined method when the first comparison result exceeds the third threshold. The sensor 23 collects the second data and analyzes the second data exceeding the second threshold and not exceeding the fourth threshold to obtain a second comparison result. Setting the fourth threshold helps to filter out the available second data and ensure the accuracy of measurement.

According to a preferred embodiment, the analysis module 212 collects the second data according to the following predetermined method and analyzes it to obtain the second comparison result: when the first comparison result exceeds the third threshold and the current time is not in the analysis period, the analysis module 212 A reference time mark is set and an analysis period of a second preset duration is set with the time of the reference time mark as a reference point. The analysis module 212 monitors the first data during the analysis period of the second preset time length and sets an intermediate time mark until the maximum rate of change falls back to the first threshold value and maintains the first preset time length every time the maximum rate of change exceeds the first threshold value. The analysis period of two preset durations is over; the analysis module 212 selectively activates the second sensor 23 in the center of gravity area or the second sensor 23 in the non-center of gravity area according to the reference time mark or the intermediate time mark to collect the second data; the analysis module 212 at When the second data exceeding the second threshold is not collected in the analysis period of the two preset time lengths, stop restarting the second sensor 23 in the analysis period of the second preset time length; When there is at least one second data of the threshold value, the analysis module 212 analyzes the second data to obtain a second comparison result. Preferably, the first preset duration is short in order to determine that the user has completed a large movement such as turning over and moving the body position and remains stable for a while, for example, two to five seconds. Because the first data is fluctuating when the user completes such a large action, there may be times when the first data exceeds the first threshold and returns to the first threshold, and when the first data falls back to the first Threshold and after a short first preset duration, it means that the large-scale action has been completed and can selectively start part of the second sensor 23 to collect data based on the set reference time mark or the first data at the intermediate time mark. second data.

According to a preferred embodiment, the second sensor 23 starts and stops in the following manner: the analysis module 212 first calculates the center of gravity area of the target to be measured according to a plurality of first data at the reference time mark or the intermediate time mark and uses a third preset The time interval of the duration alternately switches the second sensor 23 in the center of gravity area and the second sensor 23 in the non-center of gravity area according to the preset number of times; when the analysis module 212 collects second data exceeding the second threshold within the preset number of times , the analysis module 212 stops re-starting the second sensor 23 within the analysis period of the second preset time length; when the analysis module does not collect second data exceeding the second threshold within the preset number of times, the analysis module 212 will start again at the next intermediate time When the flag is set and the analysis period is not over, the above-mentioned process is repeated. When the analysis module does not collect the second data exceeding the second threshold at the end of the analysis period, the analysis module calls the smallest first data stored in the data storage module 211 during the preset period. Two comparison results. Preferably, in the present invention, only selectively turning on part of the second sensors 23 at a time can save energy more than turning on all the second sensors 23 at the same time, and the required power supply voltage is also smaller, reducing the potential danger caused by leakage. At the same time, the present invention alternately switches the second sensor 23 in the center of gravity area and the second sensor 23 in the non-center of gravity area. The factors considered include but are not limited to: in actual situations, it is impossible for only the user to , there may also be other objects, such as quilts and pillows, and even pets. The target to be tested is the sum of everything located on a smart mattress with a sweat sensor. Therefore, the center of gravity area can only feed back the center of gravity area of the target to be measured for these objects and people as a whole. Even in summer, using a thin quilt can reduce the impact of other things on the user's actual location. There is also a case where the target to be measured is a plurality of persons, for example, two persons. When these two people sleep far away, the center of gravity region may exist between the two people without any contact with these two people. If only the second sensor 23 of the center of gravity region is turned on in order to save electric energy at this moment, it cannot be measured. second data. Moreover, even if the user exists in the center of gravity area, the condition that the user's body is not in contact with the second sensor 23 or in contact with the second sensor 23 still fails to meet the measurement requirements of the second sensor 23 . There may also be a center of gravity area and a non-center of gravity area where no second sensor 23 can measure the second data temporarily, but after the user's body is slightly adjusted, the detection conditions of one or more second sensors that did not meet the detection conditions before change , the second data can be measured.

According to a preferred embodiment, the execution module 213 obtains the corresponding preset control scheme and controls the corresponding external device in the following manner: when the first comparison result is greater than or equal to the first reference value and the second comparison result is greater than the second reference value Obtain the first preset control scheme, and the execution module 213 controls at least one first external device for hypnosis and at least one second external device for cooling the user according to the first preset control scheme; when the first comparison result is greater than or equal to When the first reference value and the second comparison result are less than the second reference value, the second preset control scheme is obtained, and the execution module 213 controls at least one first external device used for hypnosis according to the second preset control scheme; when the first comparison result When it is less than the first reference value and the second comparison result is greater than or equal to the second reference value, the third preset control scheme is obtained, and the execution module 213 controls at least one second external device for cooling the user according to the third preset control scheme; when When the first comparison result is less than the first reference value and the second comparison result is less than the second reference value, the fourth preset control scheme is obtained, and the execution module 213 controls not to turn on the first external device and the second external device according to the fourth preset control scheme. ; Wherein, the first external device has a sound that can play hypnotic music and/or an electronic sleep aid aromatherapy that can release aromatherapy, and the second external device is an air conditioner and/or a fan. Preferably, the first external device may be a plurality of independently configured devices, such as an independently configured electronic music box and electronic sleep aid aromatherapy.

The intelligent system 2 controls one or more external devices by obtaining a corresponding preset control scheme after analyzing the first data and the second data.

Preferably, by optimizing the arrangement of the second sensors, the purpose of measurement can be achieved with as few sensors as possible, which can reduce manufacturing and purchase costs and improve resource utilization. Moreover, the sensor is an electronic product, although it can improve safety by protecting the circuit and reduce the probability of accidents such as leakage or short circuit. However, the densely arranged second sensors will not only cause psychological stress to users, but also affect sleep quality. Moreover, the greater the number of second sensors, the higher their potential safety risks. Therefore, by optimizing the arrangement of the second sensors, the safety can be further improved, the psychological pressure of the user can be reduced, and the negative impact of the densely arranged second sensors on the user's sleep quality can be reduced psychologically. Because when sleeping, especially in summer, most people's habits only wear shorts, underpants, underpants and short sleeves or half-naked sleeping of shorts and short sleeves. Among them, the middle part of the body is mostly covered by clothes, and the second sensor needs to be in contact with the user's skin to accurately measure the second data. Therefore, the area around the middle of the body should have as few second sensors as possible. The back and feet are most likely to be exposed during sleep. In order to improve the measurement efficiency, more second sensors should be installed on the back and legs. Therefore, the second sensor 23 is arranged on the mattress body 1 along the length direction from the first side A to the second side B of the mattress body 1 according to a trend that the density first decreases and then increases.

According to a preferred embodiment, the intelligent mattress with the sweat sensor is divided into eight equal parts in the length direction, and the first to eighth equal parts are respectively in order.

Among them, the first decile and the ninth decile are located at both ends, which are usually measurement blind areas. For example, the first decile is where the user's head is, and is usually used to place a pillow, while the ninth decile is usually a vacant area, and the user's feet usually extend to the seventh or eighth decile in a lying state. Therefore, if the second sensor is not installed in the first and ninth equal parts, the density of the second sensor 23 decreases gradually from the second to the fifth equal part, and then gradually from the fifth to the ninth equal part.

Preferably, when each user is sleeping, due to individual differences and different wearing habits, the areas of contact between the upper body and the lower body of the mattress body 1 are different. Therefore, it is not necessary to set the density of the second sensor symmetrically. The difference between the first degree and the second degree fully considers the individual differences and wearing habits of each user, further reducing the number of arrangements of the second sensors.
