[0002] Children kicking off their blankets is a common behavior, but it can easily lead to colds, stuffy noses, and fevers when the weather is a little cool, affecting the health of infants and young children.

Summary of the Invention

[0004] The main objective of this invention is to provide a method for detecting whether a child kicks off their blanket, thereby solving the technical problem of the inability to continuously and effectively monitor whether a child kicks off their blanket.

[0005] To achieve the above objectives, the present invention provides a method for detecting being kicked, the method comprising the following steps:

[0006] Step S10: Obtain the temperature of the target quilt at each target location;

[0007] Step S20: Calculate the difference between the temperature of each target location and the temperature of each target location obtained in the previous step to obtain the temperature difference of each target location.

[0008] Step S30: When at least two of the temperature differences at each target location are greater than the first temperature change threshold, or at least one temperature difference is greater than the second temperature change threshold, it is determined that the target quilt has been kicked off, and the second temperature change threshold is greater than the first temperature change threshold.

[0011] Step S12: After entering the detection mode, start timing, and after reacquiring the temperature of the target quilt at each target position collected by multiple temperature sensors, return to execute steps S20 and S30.

[0012] Specifically, step S30 involves the following steps: within the first timing period, if at least two of the temperature differences at each target location are greater than the first temperature change threshold, or if at least one temperature difference is greater than the second temperature change threshold, then it is determined that the target quilt has been kicked off, and the second temperature change threshold is greater than the first temperature change threshold.

[0013] Optionally, between step S10 and step S20, the kick detection method further includes the following steps:

[0014] Step S13: When the difference between the highest and lowest temperature values ​​at each target location is not greater than the third temperature change threshold, and the highest temperature value does not exceed the second preset temperature value, then the system enters standby mode.

[0015] Step S14: In standby mode, determine the standby temperature based on the temperature of each target location. After performing the step of acquiring the temperature of the target blanket at each target location collected by multiple temperature sensors once every first preset time, execute steps S20 and S30.

[0016] Step S30 further includes: after the first timing period, when at least two of the temperature differences at each target location are greater than the first temperature change threshold, or at least one temperature difference is greater than the second temperature change threshold, and the difference between the lowest temperature value and the standby temperature is not greater than the fourth temperature change threshold, then it is determined that the target quilt has been kicked off, and the fourth temperature change threshold is greater than the third temperature change threshold.

[0017] Optionally, after performing step S30, the kick detection method further includes:

[0018] If the number of temperature differences at each target location that exceed the first temperature change threshold is less than two, then the target quilt kicking state is determined to be released.

[0019] Optionally, the first timing period is 115 to 125 seconds, and / or the first preset time is 90 to 150 minutes.

[0020] Optionally, the first temperature change threshold is 2 degrees, the second temperature change threshold is 3 degrees, the third temperature change threshold is 2 degrees, and the fourth temperature change threshold is 2 degrees.

[0021] And / or, the first preset temperature change value is 30 degrees, and the second preset temperature value is 27 degrees.

[0022] Optionally, after performing step S30, the blanket-kicking detection method further includes: generating an alarm signal based on the presence of blanket-kicking on the target blanket, and sending it to a mobile terminal.

[0029] Optionally, the temperature sensor, the first wireless communication module, and the control device are connected by a connecting cable, and a sealing sleeve is provided at the junction of the temperature sensor, the first wireless communication module, and the control device with their respective connecting cables.

[0030] In addition, to achieve the above objectives, the present invention also provides a control terminal for use in conjunction with a blanket-kicking detection device. The blanket-kicking detection device includes a second wireless communication module and multiple temperature sensors. The multiple temperature sensors collect the temperature of the target blanket at each target position according to a second preset time interval.

[0035] This invention utilizes a blanket-kicking detection method that continuously monitors the temperature at various locations on the blanket. When the temperature change exceeds a preset threshold, it determines that the blanket has been kicked off.

[0039] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] Children kicking off their blankets is a common behavior, but it can easily lead to colds, stuffy noses, and fevers when the weather is a little cool, affecting the health of infants and young children. Therefore, it is necessary to continuously and effectively monitor whether children kick off their blankets.

[0041] Currently, there are two main types of methods for recognizing children kicking off their blankets: one is wearable hardware sensor recognition, but it is inconvenient to wear, cumbersome to operate, and can affect children's sleep quality; the other is machine learning by learning from a large number of networked images, but this requires massive data computation.

[0042] To address the aforementioned problems, this invention proposes a kick-and-behind detection method, applicable to kick-and-behind detection devices or control terminals. The kick-and-behind detection device includes multiple temperature sensors, a wireless communication module, and a control device. After the temperature sensors collect the temperature data, the control device uses the kick-and-behind detection method to detect whether a kick-and-behind state has been entered, and transmits the status to the terminal via the wireless communication module. The control terminal works in conjunction with the kick-and-behind detection device; its kick-and-behind detection program is executed by the processor on the control terminal to implement the kick-and-behind detection method of this invention.

[0043] Reference Figure 1 In one embodiment of the present invention, the kick detection method includes the following steps:

[0044] Step S10: Obtain the temperature of the target quilt at each target location;

[0045] Step S20: Calculate the difference between the temperature of each target location and the temperature of each target location obtained in the previous step to obtain the temperature difference of each target location.

[0046] Step S30: When at least two of the temperature differences at each target location are greater than the first temperature change threshold, or at least one temperature difference is greater than the second temperature change threshold, it is determined that the target quilt has been kicked off, and the second temperature change threshold is greater than the first temperature change threshold.

[0047] In this embodiment, the temperature is collected by temperature sensors in the blanket-kicking detection device. These sensors are pre-installed on the blanket being tested, either inside or on the side closest to the body, to ensure accurate temperature detection. The number of temperature sensors can be multiple, depending on the required accuracy. For example, in this embodiment, six temperature sensors are used to collect the temperature inside the blanket. Considering different sleeping positions and various instances of children kicking off the blanket, the six sensors are placed in the center of the blanket. Figure 3 As shown, this refers to the area around the body after the blanket is pulled up, to avoid failing to detect situations where the blanket is kicked off. The temperature sensor is placed on the inside of the blanket, so the temperature change is more noticeable when the blanket is kicked off. In another embodiment, the temperature sensor is placed on the outside of the blanket, resulting in greater comfort after being covered.

[0048] The time interval for the temperature sensor to acquire the temperature at each target location can be 8 seconds, 10 seconds, 15 seconds, 20 seconds, etc. In this embodiment, the temperature sensor acquires the temperature of each target location every 10 seconds, and subtracts the previously acquired temperature from the temperature of each target location to obtain the temperature difference value for each target location. When the time interval is 10 seconds, the occurrence of the blanket being kicked off can be detected in time, while avoiding excessive power consumption and the need for frequent replacement of the temperature sensor battery.

[0049] In this embodiment, the first temperature change threshold can be 2 degrees Celsius, and the second temperature change threshold can be 3 degrees Celsius. After multiple experiments, setting the temperature change thresholds to 2 and 3 degrees Celsius is consistent with the normal temperature drop range when children kick off their blankets in real life, and can effectively detect whether children are kicking off their blankets.

[0050] It should be noted that in practice, when a user covers themselves with the blanket, their body temperature heats up inside the blanket and reaches a certain temperature. If the user doesn't kick off the blanket, this temperature will remain relatively stable. When the blanket is kicked off, cold air enters the uncovered or raised area, causing a temperature drop. The temperature sensor located at this point will detect a change in temperature, typically a decrease of 2-3 degrees Celsius. Of course, the magnitude of the drop will vary depending on the external temperature. Generally, a 3-degree drop is sufficient to preliminarily determine that the blanket has been kicked off. However, if the blanket is raised, the temperature drop may not be as significant. But if at least two temperature sensors detect a 2-degree drop, it indicates that the blanket has been kicked off. Therefore, in this embodiment, the first temperature change threshold can be 2 degrees Celsius, and the second temperature change threshold can be 3 degrees Celsius.

[0051] In this embodiment, by monitoring the temperature at various target locations on the blanket, and considering different sleeping postures, different conditions for judging the kicking off of the blanket are adopted to ensure that the judgment of the kicking off of the blanket is accurate and error-free.

[0052] The kick-over detection method of this invention does not require a high-performance processor and does not require massive data calculations. It only requires comparing temperatures and temperature differences. At the same time, the kick-over detection device of this invention is set on the blanket and does not affect the child's sleep.

[0053] Based on the above embodiments, further, between step S10 and step S20, the kick detection method further includes the following step:

[0054] Step S11: When any temperature value at any target location exceeds the first preset temperature value, the detection mode is entered.

[0055] Step S12: After entering the detection mode, start timing, and after reacquiring the temperature of the target quilt at each target position collected by multiple temperature sensors, return to execute steps S20 and S30.

[0056] Specifically, step S30 involves the following steps: within the first timing period, if at least two of the temperature differences at each target location are greater than the first temperature change threshold, or if at least one temperature difference is greater than the second temperature change threshold, then it is determined that the target quilt has been kicked off, and the second temperature change threshold is greater than the first temperature change threshold.

[0057] like Figure 2 As shown, in this embodiment, when any temperature value at each target location exceeds 30 degrees Celsius, indicating someone has covered themselves with a blanket, the detection mode is activated, and timing begins. After re-acquiring the temperatures of the target blanket at each target location from multiple temperature sensors, the difference between the temperature at each target location and the previously acquired temperature is calculated to obtain the temperature difference for each target location. This method distinguishes between the detection mode and other modes to control power consumption. Since this method is based on temperature sensors, wireless communication modules, control devices, and other equipment, and these devices are battery-powered, it is important to control power consumption to avoid frequent power outages affecting the implementation of this blanket detection method. In other modes, the equipment consumes less power, effectively extending standby time.

[0058] The first preset temperature change value can be 30 degrees Celsius, and the first timing time can be 115 to 125 seconds. The first timing time can be 115 seconds, 120 seconds, 125 seconds, etc. In this embodiment, the timing time is 2 minutes, or 120 seconds. Within two minutes, if at least two temperature differences at each target location are greater than 2 degrees Celsius, or at least one temperature difference is greater than 3 degrees Celsius, then it is determined that the target blanket has been kicked off. It should be noted that this embodiment detects whether a child kicks off the blanket while sleeping normally on their back. Because if the blanket is kicked off while sleeping on their back, the temperature drops rapidly, generally decreasing by 2-3 degrees Celsius within 2 minutes; therefore, the timing time is set to 2 minutes.

[0059] Based on the above embodiments, further, between step S10 and step S20, the kick detection method further includes the following step:

[0060] Step S13: When the difference between the highest and lowest temperature values ​​at each target location is not greater than the third temperature change threshold, and the highest temperature value does not exceed the second preset temperature value, then the system enters standby mode.

[0061] Step S14: In standby mode, determine the standby temperature based on the temperature of each target location. After performing the step of acquiring the temperature of the target blanket at each target location collected by multiple temperature sensors once every first preset time, execute steps S20 and S30.

[0062] Specifically, step S30 is as follows: after the first timing period, if at least two of the temperature differences at each target location are greater than the first temperature change threshold, or if at least one temperature difference is greater than the second temperature change threshold, and the difference between the lowest temperature value and the standby temperature is not greater than the fourth temperature change threshold, then it is determined that the target quilt has been kicked off, and the fourth temperature change threshold is greater than the third temperature change threshold.

[0063] In this embodiment, the first preset time can be 90 to 150 minutes; the second preset temperature value can be 27 degrees; the third temperature change threshold can be 2 degrees; and the fourth temperature change threshold can be 2 degrees.

[0064] like Figure 2 As shown, in this embodiment, when the difference between the highest and lowest temperatures at each target location is less than or equal to 2, and the highest temperature does not exceed 27 degrees Celsius, the device enters standby mode. In standby mode, the lowest temperature is defined as the standby temperature, and the temperature at each location is collected every 2 hours. A highest temperature not exceeding 27 degrees Celsius indicates that the blanket is not in use. Entering standby mode and collecting the temperature every 2 hours saves power and extends the device's standby time.

[0065] When any temperature value at any target location exceeds 30 degrees Celsius, indicating that someone has covered themselves with the blanket, the detection mode is activated, and a timer begins. After re-acquiring the temperatures of the target blanket at each target location from multiple temperature sensors, the temperature at each target location is calculated to obtain the temperature difference value for each target location. After 2 minutes, if at least two of the temperature differences at each target location are greater than 2 degrees Celsius, or at least one temperature difference is greater than 3 degrees Celsius, and the difference between the lowest temperature value and the standby temperature value is not greater than 2, then it is determined that the target blanket has been kicked off.

[0066] It should be noted that when a child is sleeping on their side, the temperature of the blanket on the side away from their body will slowly decrease. However, because the body constantly dissipates heat, the temperature on the side away from the body will not drop to the temperature when the blanket is unused. At this point, the temperature will be greater than 2 degrees Celsius compared to the temperature when the blanket is unused. If, after two minutes, the difference between the lowest temperature and the standby temperature is greater than 2, it is considered that the child has not kicked off the blanket, which is a normal phenomenon of temperature change when sleeping on their side. Only when the difference is no greater than 2 after two minutes is it considered that the child has kicked off the blanket.

[0067] Optionally, after performing step S30, the kick detection method further includes:

[0068] If the number of temperature differences at each target location that exceed the first temperature change threshold is less than two, then the target quilt kicking state is determined to be released.

[0069] In this embodiment, after detecting the state of kicking off the blanket, if the number of temperature differences greater than the first temperature change threshold is less than two, it is considered that the blanket is covered properly, and the kicking off the blanket state of the target blanket is released, so as to avoid the kicking off the blanket state from being present indefinitely and affecting the judgment.

[0070] Optionally, after performing step S30, the kick detection method further includes:

[0071] An alarm signal is generated based on whether the target quilt has been kicked off, and then sent to the mobile terminal.

[0072] In this embodiment, after detecting that the target quilt has been kicked off, the control device generates an alarm signal and sends the alarm signal to the mobile terminal through the wireless communication module, reminding parents or other guardians to cover the child with the quilt in time.

[0073] This invention also proposes a blanket-kicking detection device, the data transceiver comprising: multiple temperature sensors, wherein the multiple temperature sensors collect the temperature of the target blanket at each target location at preset time intervals; and

[0074] A first wireless communication module, wherein multiple temperature sensors are connected to the first wireless communication module;

[0075] Control device, the control device comprising:

[0076] Memory;

[0077] A processor, and a kick detection program stored in the memory and executed by the processor, wherein the kick detection program, when executed by the processor, implements the kick detection method as described in any one of claims 1 to 7.

[0078] Optionally, the temperature sensor, the first wireless communication module, and the control device are connected by a connecting cable, and a sealing sleeve is provided at the junction of the temperature sensor, the first wireless communication module, and the control device with their respective connecting cables.

[0079] In this embodiment, the temperature sensor, the first wireless communication module, and the control device are enclosed in a sealed housing, with a sealing sleeve at the connection point of the connecting wires. The battery is a removable battery that is magnetically charged, and the sealed housing achieves a waterproof effect. Since quilts are daily necessities and require washing periodically, making the temperature sensor, the first wireless communication module, and the control device waterproof eliminates the need to disassemble them when washing the quilt, facilitating cleaning. The magnetic charging method also prevents water from entering the charging port and causing the device to malfunction.

[0084] Memory;
