Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.

The intelligent mattress that this application embodiment relates to, including mattress body and peripheral part, wherein, the mattress body divide into contact layer and functional layer, and the peripheral part includes intelligent control ware. Specifically, the contact layer directly contacts with the human body, the uppermost surface of the contact layer is wrapped with a bedspread made of cotton, hemp and other materials, the inside of the bedspread is filled with fillings such as sponge to provide soft and comfortable touch feeling for the human body, the functional layer is embedded inside the contact layer and close to the surface of the contact layer, and the bedspread is composed of various sensors and electric functional elements, wherein the sensors comprise a certain number of temperature sensors for collecting temperature data of the functional layer, the electric functional elements comprise a certain number of electric heating elements such as carbon film heating sheets and the like, and the temperature sensors and the electric heating elements are connected with the intelligent controller through a flexible circuit. The intelligent controller comprises an intelligent control unit and a temperature control circuit, wherein the intelligent control unit can store preset temperature data (preset temperature data) and acquire the current temperature data acquired by the temperature sensor, the current temperature data and the preset temperature data are compared, if the current temperature data are lower than the preset temperature data, the heating power of the electric heating element is increased by the control circuit, and if the current temperature data are higher than the preset temperature data, the heating power of the electric heating element is reduced by the control circuit, so that the current temperature data gradually tend to the preset temperature data. However, because the temperature sensor is wrapped under the surface layer of the bed cover of the contact layer, and the heat conductivity of the fabric of the bed cover is generally not strong, a large error may exist between the current temperature data measured by the temperature sensor and the real temperature data of the surface of the contact layer, and in addition, the temperature sensor itself may malfunction, output signal error and other abnormalities may occur, so that temperature control errors are easily generated, the surface of the bed cover is overheated or overcooled, the preset target temperature value cannot be reached, the comfort level of a user is further affected, and meanwhile, the human health may be damaged due to temperature runaway, and the mattress may be damaged.
In order to overcome the above defects, embodiments of the present application provide an intelligent mattress temperature control fault automatic alarm processing system and method, and specifically, as shown in fig. 1, it is a schematic structural diagram of the intelligent mattress temperature control fault automatic alarm processing system according to the first embodiment of the present application. As can be seen from the figures, as an embodiment of the present application, the intelligent mattress temperature control fault automatic alarm processing system includes:
a mattress body 101 and an intelligent controller 102. The mattress body 101 comprises a contact layer 1011 and a functional layer 1012, the functional layer 102 is embedded in the contact layer 1011, the functional layer comprises an electric heating element and a temperature sensor, the electric heating element is used for heating the contact layer, the temperature sensor is used for collecting temperature data in the functional layer, and the electric heating element and the temperature sensor are connected with the intelligent controller 102 through a flexible conducting circuit.
In this embodiment, the functional layer 1012 includes a plurality of electrical heating elements and a plurality of temperature sensors, the plurality of electrical heating elements and the plurality of temperature sensors are arranged in an array within the functional layer 1012, each electrical heating element and each temperature sensor has a corresponding number, and each electrical heating element corresponds to one temperature sensor.
The intelligent controller 102 includes an intelligent control unit 1021 and a temperature control circuit 1022, where the intelligent control unit 1021 is configured to compare current temperature data acquired by the temperature sensor with preset temperature data, and generate a comparison result. In this embodiment, the preset temperature data may be a temperature value set manually by a user according to a use requirement, or may be automatically set according to a sleep depth of the user or a health requirement of the user. The intelligent control unit 1021 acquires temperature data acquired by the temperature sensor at preset time intervals, (for example, the temperature data acquired by the temperature sensor is acquired every 10S), and for the temperature data acquired by the temperature sensor (namely, current temperature data) acquired every time, the intelligent control unit 1021 determines whether the functional layer 1012 normally operates according to preset conditions, namely, determines whether the temperature sensor in the functional layer 1012 normally operates, and determines whether the temperature of the area where the temperature sensor is located meets a preset temperature by heat generated by the electric heating element corresponding to the temperature sensor. If the functional layer 1012 works normally, the working state of the electric heating element is adjusted through the temperature control circuit 1022 according to the current temperature data, and if the functional layer works abnormally, the abnormal type is alarmed according to a preset condition, and meanwhile, a preset control mode is adopted to control the electric heating element.
Specifically, for each of the temperature sensors, the intelligent control unit 1021 compares the current temperature data acquired by the temperature sensor with a first preset temperature threshold, and determines whether the current temperature data is within the first preset temperature threshold, where the first preset temperature threshold may be, for example, 20 degrees below zero to 80 degrees, or another preset temperature threshold. And if the current temperature data is not within the first preset temperature threshold, determining that the temperature sensor is abnormal. Because the temperature of the intelligent mattress is unlikely to be lower than minus 20 degrees and is unlikely to be higher than 80 degrees under normal conditions, the current temperature data acquired by the temperature sensor is in the range of minus 20 degrees to 80 degrees, namely, within the first preset temperature threshold. And when the current temperature data acquired by the temperature sensor is not within the first preset temperature threshold, the temperature sensor is judged to have a fault. At this time, in order to ensure that the electric heating element corresponding to the temperature sensor normally operates, the average value of the current temperature data acquired by other temperature sensors around the temperature sensor is used as the current temperature data acquired by the temperature sensor, for example, the average value of the current temperature data acquired by 8 temperature sensors around the temperature sensor, and the electric heating element corresponding to the temperature sensor is controlled according to the average value of the current temperature data acquired by other temperature sensors around the temperature sensor.
If the current temperature data is within the first preset temperature threshold, further judging whether the current temperature data is within a second preset temperature threshold, if the current temperature data is not within the second preset temperature threshold, determining that the power of the electric heating element corresponding to the temperature sensor is too high, and simultaneously controlling the temperature control circuit to stop supplying power to the electric heating element. In this embodiment, the second preset temperature threshold may be 20 degrees below zero to 50 degrees, and if the current temperature data is not within the second preset temperature threshold, that is, the current temperature data is higher than 50 degrees, it is determined that the power of the electric heating element corresponding to the temperature sensor is too large, so that the temperature around the temperature sensor is higher than the human body safety temperature, and therefore, the temperature control circuit 1022 may be controlled to stop supplying power to the electric heating element, so as to reduce the temperature around the temperature sensor.
If the current temperature data is within the second preset temperature threshold value, namely within minus 20 ℃ to 50 ℃, the temperature sensor works normally, and the heating temperature of the corresponding area of the electric heating element corresponding to the temperature sensor is within the human body safety temperature range. However, because the temperature sensor is wrapped under the surface layer of the bed cover of the contact layer, and the thermal conductivity of the bed cover fabric is generally not strong, the current temperature data measured by the temperature sensor and the real temperature data of the surface of the contact layer may have a large error. Therefore, in order to avoid the above errors, the mapping coefficient between the historical temperature data and the heat generation amount can be determined according to the historical temperature data collected by the temperature sensor and the heat generation amount obtained by integrating the historical working power of the electric heating element corresponding to the temperature sensor for a plurality of historical temperature data. After the mapping coefficient is determined, theoretical temperature data collected by the temperature sensor is determined according to the mapping coefficient and the current heat productivity of the electric heating element corresponding to the temperature sensor, the theoretical temperature data and the current temperature data are compared, and then the working state of the electric heating element corresponding to the temperature sensor is controlled through the temperature control circuit. Specifically, the working power of the electric heating element and the temperature value measured by the temperature sensor can be recorded periodically (for example, once every minute) every time the intelligent mattress works; the working power is used for integral operation to obtain the heating value of the electric heating element within one minute, and then the mapping coefficient between the heating value and the temperature value can be calculated according to the temperature value measured by the temperature sensor; therefore, when the intelligent mattress works at the time, the heat value can be obtained according to the mapping coefficient calculated by the accumulated data (such as the data in the previous month) and the integral during the work at the time, a theoretical temperature value is calculated, the theoretical temperature value is compared with the actually measured current temperature value, whether the current temperature value is obviously deviated from the theoretical temperature value or not is judged, if the current temperature value is obviously deviated from the theoretical temperature value, the heating power of the electric heating element corresponding to the temperature sensor is controlled according to the theoretical temperature value, and the heating temperature of the corresponding area of the intelligent mattress by the heat emitted by the electric heating element tends to the theoretical temperature value.
The intelligent mattress temperature control fault automatic alarm processing system can effectively avoid temperature control errors, further enables the surface of the bedspread to reach a preset target temperature value, improves comfort level of a user, avoids temperature runaway simultaneously, further guarantees human health, and protects the mattress.
Fig. 2 is a schematic structural diagram of an intelligent mattress temperature control fault automatic alarm processing system according to a second embodiment of the present application. As can be seen from fig. 2, the intelligent mattress temperature control fault automatic alarm processing system of the embodiment includes:
The mattress body 201 comprises a contact layer 2011, a functional layer 2012 and a hardness adjusting layer 2013, the functional layer 102 is embedded in the contact layer 1011, the functional layer comprises a plurality of electric heating elements 20121, a plurality of temperature sensors 20122 and a plurality of sweat sensors 20123, the electric heating elements 20121 are used for heating the contact layer, the temperature sensors 20122 are used for collecting temperature data in the functional layer, and the sweat sensors 20123 are used for collecting sweat secretion states of a user, so that a preset heating temperature of the intelligent mattress is determined according to the sweat secretion states of the user. The electrical heating elements 20121, the temperature sensor 20122 and the sweat sensor 20123 are connected to the intelligent controller 202 by flexible conductive traces. In this embodiment, the electrical heating elements 20121 and the temperature sensors 20122 may be arranged in an array in the functional layer, each electrical heating element 20121 corresponds to one temperature sensor 20122, and each of the electrical heating element 20121, the temperature sensor 20122 and the sweat sensor 20123 corresponds to a number.
The hardness adjusting layer 2013 is located below the functional layer 2012, the hardness adjusting layer 2013 comprises a plurality of independent chambers, each independent chamber is correspondingly provided with an air duct, the air duct is used for inflating the corresponding chamber to increase the air pressure in the corresponding chamber, so that the hardness of the mattress region corresponding to the chamber is increased, or the corresponding chamber is exhausted to reduce the air pressure in the corresponding chamber, so that the hardness of the mattress region corresponding to the chamber is reduced. Each chamber of the hardness adjusting layer 2013 is connected with the inflating device 204 through an air duct, and then the inflating device 204 inflates and deflates the hardness adjusting layer 2013 so as to change the hardness of the intelligent mattress.
The intelligent controller 202 includes an intelligent control unit 2021 and a temperature control circuit 2022, and the intelligent control unit 2021 is configured to compare current temperature data acquired by the temperature sensor with preset temperature data, and generate a comparison result. In this embodiment, the preset temperature data may be preset temperature data automatically set according to the sweat secretion state of the user during sleep. The intelligent control unit 2021 obtains temperature data acquired by the temperature sensor at preset time intervals, (for example, obtaining the temperature data acquired by the temperature sensor every 10S), and for the temperature data (i.e., the current temperature data) acquired by the temperature sensor obtained each time, the intelligent control unit 1021 determines whether the functional layer 2012 normally operates according to preset conditions, that is, determines whether the temperature sensor in the functional layer 2012 normally operates, and whether the temperature of the area where the temperature sensor is located meets a preset temperature due to heat generated by the electric heating element corresponding to the temperature sensor. If the functional layer 2012 works normally, the working state of the electric heating element is adjusted through the temperature control circuit 2022 according to the current temperature data, and if the functional layer works abnormally, the abnormal type is alarmed according to a preset condition, and meanwhile, a preset control mode is adopted to control the electric heating element.
Specifically, for each temperature sensor 20122, the intelligent control unit 2021 compares the current temperature data collected by the temperature sensor with a first preset temperature threshold, and determines whether the current temperature data is within the first preset temperature threshold, where the first preset temperature threshold may be, for example, 20 degrees below zero to 80 degrees, or another preset temperature threshold. And if the current temperature data is not within the first preset temperature threshold, determining that the temperature sensor is abnormal. At this time, the intelligent control unit 2021 sends alarm information to the temperature control circuit 2022, the type of the alarm information is that the temperature sensor 20122 is abnormal in operation, and simultaneously sends the number of the abnormal temperature sensor to the temperature control circuit 2022, and sends the alarm information to the intelligent terminal through the communication module 203 to remind the user. The intelligent terminal in this embodiment may be a smart phone or a tablet computer, and after receiving the alarm information, the intelligent terminal may display the type of the alarm information and the number of the abnormal temperature sensor 20122. Because the temperature of the intelligent mattress is unlikely to be lower than minus 20 degrees and is unlikely to be higher than 80 degrees under normal conditions, the current temperature data collected by the temperature sensor 20122 is in the range of minus 20 degrees to 80 degrees, that is, within the first preset temperature threshold. When the current temperature data acquired by the temperature sensor 20122 is not within the first preset temperature threshold, it indicates that the temperature sensor 20122 has a fault. At this time, in order to ensure that the electrothermal element 20121 corresponding to the temperature sensor 20122 operates normally, the temperature control circuit 2022 uses the mean value of the current temperature data acquired by the other temperature sensors 20122 around the temperature sensor 20122 as the current temperature data acquired by the temperature sensor 20122, for example, the mean value of the current temperature data acquired by the 8 temperature sensors 20122 around the temperature sensor 20122, and controls the electrothermal element 20121 corresponding to the temperature sensor 20122 according to the mean value of the current temperature data acquired by the other temperature sensors 20122 around the temperature sensor 20122.
If the current temperature data is within the first preset temperature threshold, further determining whether the current temperature data is within a second preset temperature threshold, and if the current temperature data is not within the second preset temperature threshold, determining that the power of the electric heating element 20121 corresponding to the temperature sensor 20122 is too high, at this time, the intelligent control unit 2021 sends alarm information to the temperature control circuit 2022, and simultaneously sends the alarm information to the intelligent terminal through the communication module 203. The type of the alarm information is that the electric heating element 20122 has over-power and the number of the electric heating element 20122. The temperature control circuit 2022 stops supplying power to the electric heating element after receiving the alarm information. In this embodiment, the second preset temperature threshold may be 20 degrees below zero to 50 degrees, and if the current temperature data is not within the second preset temperature threshold, that is, the current temperature data is higher than 50 degrees, it is determined that the power of the electric heating element corresponding to the temperature sensor is too large, so that the temperature around the temperature sensor 20122 is higher than the human body safety temperature, and therefore, the temperature control circuit 1022 may be controlled to stop supplying power to the electric heating element, so as to reduce the temperature around the temperature sensor 20122.
If the current temperature data is within the second preset temperature threshold, that is, within-20 to-50 degrees, it indicates that the temperature sensor 20122 is working normally, and the heating temperature of the corresponding area by the electric heating element 20121 corresponding to the temperature sensor 20122 is within the human body safety temperature range. However, since the temperature sensor 20122 is wrapped under the surface layer of the bed cover of the contact layer, and the thermal conductivity of the bed cover fabric is generally not strong, the current temperature data measured by the temperature sensor 20122 may have a large error from the real temperature data of the surface of the contact layer. Therefore, in order to avoid the above errors, a mapping coefficient between the historical temperature data and the heat generation amount may be determined according to the historical temperature data collected by the temperature sensor 20122 and the heat generation amount obtained by integrating the historical operating power of the corresponding electric heating element 20122 of the temperature sensor for a plurality of historical temperature data. After the mapping coefficient is determined, theoretical temperature data collected by the temperature sensor 20122 is determined according to the mapping coefficient and the current heat productivity of the electric heating element 20121 corresponding to the temperature sensor 20122, the theoretical temperature data and the current temperature data are compared, and then the working state of the electric heating element 20121 corresponding to the temperature sensor 20122 is controlled through the temperature control circuit. Specifically, the working power of the electric heating element and the temperature value measured by the temperature sensor can be recorded periodically (for example, once every minute) every time the intelligent mattress works; the working power is used for integral operation to obtain the heating value of the electric heating element 20121 in one minute, and then the mapping coefficient between the heating value and the temperature value can be obtained through calculation according to the temperature value measured by the temperature sensor 20122; therefore, when the intelligent mattress works at the time, the heat value can be obtained according to the mapping coefficient calculated by the accumulated data (such as the data in the previous month) and the integral during the work at the time, a theoretical temperature value is calculated, the theoretical temperature value is compared with the actually measured current temperature value, whether the current temperature value is obviously deviated from the theoretical temperature value or not is judged, if the current temperature value is obviously deviated from the theoretical temperature value, the heating power of the electric heating element corresponding to the temperature sensor is controlled according to the theoretical temperature value, and the heating temperature of the corresponding area of the intelligent mattress by the heat emitted by the electric heating element tends to the theoretical temperature value.
The intelligent mattress temperature control fault automatic alarm processing system can effectively avoid temperature control errors, further enables the surface of the bedspread to reach a preset target temperature value, improves comfort level of a user, avoids temperature runaway simultaneously, further guarantees human health, and protects the mattress.
Fig. 3 is a flowchart of an intelligent mattress temperature control fault automatic alarm processing method according to a third embodiment of the present application. In this embodiment, the intelligent mattress temperature control fault automatic alarm processing method includes:
s301: the method comprises the steps of obtaining current temperature data collected by each temperature sensor, comparing the current temperature data collected by the temperature sensor with a first preset temperature threshold value for each temperature sensor, judging whether the current temperature data are within the first preset temperature threshold value, determining that the temperature sensor is abnormal if the current temperature data are not within the first preset temperature threshold value, sending the serial number of the temperature sensor to an intelligent terminal, and taking the average value of the current temperature data collected by other temperature sensors around the temperature sensor as the current temperature data collected by the temperature sensor.
Because the temperature of the intelligent mattress is unlikely to be lower than minus 20 degrees and is unlikely to be higher than 80 degrees under normal conditions, the current temperature data acquired by the temperature sensor is in the range of minus 20 degrees to 80 degrees, namely, within the first preset temperature threshold. And when the current temperature data acquired by the temperature sensor is not within the first preset temperature threshold, the temperature sensor is judged to have a fault. At this time, in order to ensure that the electric heating element corresponding to the temperature sensor normally operates, the temperature control circuit uses the average value of the current temperature data acquired by other temperature sensors around the temperature sensor as the current temperature data acquired by the temperature sensor, for example, the average value of the current temperature data acquired by 8 temperature sensors around the temperature sensor, and controls the electric heating element corresponding to the temperature sensor according to the average value of the current temperature data acquired by other temperature sensors around the temperature sensor.
S302: if the current temperature data is within the first preset temperature threshold, further judging whether the current temperature data is within a second preset temperature threshold, if the current temperature data is not within the second preset temperature threshold, determining that the power of the electric heating element corresponding to the temperature sensor is too high, and simultaneously controlling the temperature control circuit to stop supplying power to the electric heating element.
Specifically, the second preset temperature threshold may be 20 degrees below zero to 50 degrees, and if the current temperature data is not within the second preset temperature threshold, that is, the current temperature data is higher than 50 degrees, it is determined that the power of the electric heating element corresponding to the temperature sensor is too high, so that the temperature around the temperature sensor is higher than the human body safety temperature, and therefore, the temperature control circuit may be controlled to stop supplying power to the electric heating element, so as to reduce the temperature around the temperature sensor.
S303: if the current temperature data is within the second preset temperature threshold, determining a mapping coefficient between historical temperature data and heating power according to the historical temperature data acquired by the temperature sensor and the heating power obtained by integrating the historical working power of the electric heating element corresponding to the temperature sensor, determining theoretical temperature data acquired by the temperature sensor according to the mapping coefficient and the current heating power of the electric heating element corresponding to the temperature sensor, comparing the theoretical temperature data with the current temperature data, and further controlling the working state of the electric heating element corresponding to the temperature sensor through the temperature control circuit.
Specifically, the working power of the electric heating element and the temperature value measured by the temperature sensor can be recorded periodically (for example, once every minute) every time the intelligent mattress works; the working power is used for integral operation to obtain the heating value of the electric heating element within one minute, and then the mapping coefficient between the heating value and the temperature value can be calculated according to the temperature value measured by the temperature sensor; therefore, when the intelligent mattress works at the time, the heat value can be obtained according to the mapping coefficient calculated by the accumulated data (such as the data in the previous month) and the integral during the work at the time, a theoretical temperature value is calculated, the theoretical temperature value is compared with the actually measured current temperature value, whether the current temperature value is obviously deviated from the theoretical temperature value or not is judged, if the current temperature value is obviously deviated from the theoretical temperature value, the heating power of the electric heating element corresponding to the temperature sensor is controlled according to the theoretical temperature value, and the heating temperature of the corresponding area of the intelligent mattress by the heat emitted by the electric heating element tends to the theoretical temperature value.
The intelligent mattress temperature control fault automatic alarm processing method provided by the embodiment of the application can obtain the technical effects similar to those of the system embodiment, and is not repeated here.
