This application claims the benefit and priority of Chinese patent application No. 202310529618.6, filed on May 11, 2023, disclosure of which is hereby incorporated by reference in its entirety.
The present application relates to the technical field of smart clothing, in particular to a method and device for cutting off the power supply of heated clothing based on undressing detection.
Existing heated clothing products are mainly used in cold outdoor environments, which are powered by a mobile power supply, and the electric control board system controls the heating sheet sewn on the clothing to generate heat, so as to provide heat for the user's body surface. The generally designed battery can be used for heating clothes for 4-5 hours. After the power consumption is completed, the mobile power supply needs to be recharged. After the user enters the indoor warm place from the cold outdoor place, due to the increase of the ambient temperature, the user will naturally take off the heated clothing. However, according to the feedback from the vast majority of users, they often forget to turn off the power supply of the heated clothing after entering the room, which causes the battery power to be wasted, and the mobile power supply has no power to use when going out for use next time.
In view of the above problems, the present application proposes a method and device for cutting off the power supply of heated clothing based on undressing detection, which mainly solves the problem that existing heated clothing products do not have the function of automatically cutting off the power input.
To solve the above technical problems, the first aspect of the present application proposes a method for cutting off the power supply of heated clothing based on undressing detection, which comprises the following steps:
Setting a countdown for a preset time, and continuously detecting the user's breathing movement within the preset time, if no breathing movement is present within the preset time, then triggering to cut off a power input for a heating module.
In some implementations, the countdown of the preset time is reset after each detection of the breathing movement.
In some implementations, the preset time is set to 3-5 minutes.
In some implementations, the detection of the breathing movement comprising: acquiring its own three-axis data at intervals by a three-axis acceleration sensor arranged in a heated clothing, reading the three-axis data at intervals, sequentially splicing, reversing, and taking absolute values, and de-shaking processing, obtaining a corresponding motion posture, counting whether an average angle change of a plurality of the motion postures exceeds 3 degrees of deflection within the preset time, if not, determining that no breathing movement is present and triggering to cut off the power input for the heating module.
In some implementations, it further comprises: accumulating a number of breathing movements within the preset time, determining whether the number of breathing movements reaches a threshold, and triggering to cut off the power input for the heating module if the number of breathing movements does not reach the threshold.
In some implementations, the threshold is set to 3 to 5 times.
In some implementations, the detection of the breathing movement comprises: acquiring its own three-axis data at intervals by a three-axis acceleration sensor arranged in a heated clothing, if a discrete three-axis data forms a stable cycle in a time direction, accumulating each cycle as one breathing movement.
The second aspect of the present application proposes a device for cutting off power supply of heated clothing based on undressing detection comprising:
A time preset module, configured to set a countdown of a preset time;
An movement detection module, configured to continuously detect a breathing movement of a user within the preset time;
A power cut-off module, configured to determine whether the breathing movement is present within the preset time, and if not, trigger to cut off a power input for a heating module.
The third aspect of the present application proposes device for cutting off power supply of heated clothing based on undressing detection, comprising a memory, a processor and a communication module, wherein,
The memory is configured to store executable program codes;
The processor is coupled to the memory;
The processor is configured to invoke the executable program code stored in the memory to execute the above mentioned method for cutting off the power supply of heated clothing based on undressing detection.
The fourth aspect of the present application proposes a computer storage medium, wherein the computer storage medium stores computer instructions, and when the computer instructions are invoked, computer instructions execute the above mentioned method for cutting off power supply of heated clothing based on undressing detection.
The beneficial effect of the present application is: to continuously detect the breathing movement of the human body. When the user takes off his clothes, if there is no movement trigger within the preset time, the power input for the heating module will be cut off to reduce the meaningless power consumption of the mobile power supply, so as to achieve the purpose of energy saving.

In this embodiment, the heated clothing should be provided with a single-chip microcomputer control module for controlling the heated clothing. This solution is designed based on the original single-chip microcomputer architecture, and the original hardware is used as much as possible to increase the power cut-off function. Specifically, in step 101, the preset time can be manually set, such as burning into the single-chip microcomputer through a program, or written into the single-chip microcomputer by the user through the mobile phone APP. After the preset time is set, generate a subroutine to run. This subroutine is parallel to the main program of heated clothing to count down, and determines whether to cut off the power according to the subsequent trigger conditions, and the preset time is set to 3-5 minutes.
There may be various means for detecting the user's breathing movement, such as detecting the airflow in the user's nasal cavity, or the rise and fall of the chest cavity. In this embodiment, in order to reduce the cost of the detection device and reduce the volume of the product, a three-axis acceleration sensor is used to obtain the user's chest rise and fall, or the acceleration generated when the human body moves. It should be known that the detection of breathing movement is a technical means, and its purpose is still to reflect the state of the heated clothing, whether it is put on or taken off by the user.
In this embodiment, the heating module specifically refers to a heating sheet, a heating wire, or other forms of heating devices installed in the heated clothing. If no breathing movement is detected within the preset time, the power input for the heating module will be triggered to be cut off. When the power supply for the heating module is cut off, the power consumption of the entire heated clothing will drop precipitously, and only the single-chip microcomputer will keep running with low power consumption. If a breathing movement is detected within the preset time, the countdown of the preset time will be reset after each detection of the breathing movement, and the above subroutine will start counting down again. That is to say, every time a breathing movement is detected, there will be a heating time of at least 3 minutes (assuming the preset time is set to 3 minutes). If the user needs to leave immediately after entering the room for a short time, she/he can directly put on the heated clothing and leave without restarting the heating or waiting for the heated clothing to reach the expected temperature.
In this embodiment, one of the alternative implementations is provided to replace or supplement step 103, 104. The detection of the breathing movement comprising: acquiring its own three-axis data at intervals by a three-axis acceleration sensor arranged in a heated clothing, reading the three-axis data at intervals, sequentially splicing, reversing, and taking absolute values, and de-shaking processing, obtaining a corresponding motion posture, counting whether an average angle change of a plurality of the motion postures exceeds 3 degrees of deflection within the preset time, if not, determining that no breathing movement is present and triggering to cut off the power input for the heating module. In this alternative, the condition for power cutoff is to count whether the average angle change of a plurality of the motion postures exceeds 3 degrees of deflection within a preset time, the average angle change can effectively reflect whether the heated clothing is actually taken off. Even if the heated clothing is taken off and located in an unstable environment (for example, the heated clothing is placed on the back of the seat and then falls to the ground), the angle deflection will not exceed 3 degrees within the preset time of 3 minutes deflection. Even if the posture of the heated clothing changes in a short period of time, it will stabilize quickly without human intervention. Therefore, it will be reset at the beginning of the preset time, and the power will be cut off within 3-5 minutes.

For the above steps 201 to 203, please refer to the detailed description of steps 101 to 103 in the first Embodiment, which will not be repeated in this embodiment of the present application.
In this embodiment, another further optional implementation is provided to replace or supplement step 203, which also includes the following step 204.
In Step 204, accumulating a number of breathing movements within the preset time, determining whether the number of breathing movements reaches a threshold, and triggering to cut off the power input for the heating module if the number of breathing movements does not reach the threshold. In order to avoid falsely triggering the power cutoff operation and putting the user in danger of hypothermia, this embodiment proposes the concept of “breathing frequency threshold”. By detecting the number of accumulated breathing movements within a preset time, it is detected whether the heated clothing is actually worn by the user. Specifically, based on experience, the threshold should be set to 3 to 5 times within 3 minutes, and if the preset time is increased to 5 minutes, the threshold should be set to more than 10 times. Obviously, in some extreme situations in the wild, the user may be about to suffer extreme threats and have to reduce his own breathing rate, so an excessively high threshold should not be used to determine whether the heated clothing is still worn on the user.
Specifically, the detection of the breathing movement comprises: acquiring its own three-axis data at intervals by a three-axis acceleration sensor arranged in a heated clothing, if a discrete three-axis data forms a stable cycle in a time direction, accumulating each cycle as one breathing movement. In this alternative, only three-axis data that stably form a complete cycle can be identified as breathing movement.

A time preset module 301, configured to set the countdown of the preset time.
In this embodiment, the heated clothing should be equipped with a single-chip microcomputer control module for controlling the heated clothing. This solution is designed based on the original single-chip microcomputer architecture, and the original hardware is used as much as possible to increase the power cut-off function. Specifically, the time preset module 301 can be a peripheral hardware module of the single-chip microcomputer, or a software module embedded in the single-chip microcomputer. The above-mentioned preset time can be set manually, such as burning it into the single-chip microcomputer through a program, or writing into the single-chip microcomputer by the user through the mobile phone APP. After the preset time is set, generate a subroutine to run. This subroutine is parallel to the main program of heated clothing to count down, and determines whether to cut off the power according to the subsequent trigger conditions, and the preset time is set to 3-5 minutes.
A motion detection module 302, configured to continuously detect the breathing motion of the user within a preset time.

A power cut-off module 303, configured to determine whether there is a breathing movement within a preset time, and if not, triggering to cut off the power input for the heating module.
In this embodiment, the power cut-off module 303 needs to have at least two functions, one is the logical operation function for determining whether there is a breathing movement within a preset time, and the other is the data sending function, which sends the instruction to cut off the power input to the data receiving end of the power supply, physically disconnects the current between the heated clothing and the power supply, and provides a reliable cut-off action.
In this embodiment, the specific execution logic of the power cut-off module can refer to the first Embodiment or the second Embodiment, which will not be repeated here.
