Description

Technical Field

[0001] The present application relates to the field of intelligent voice control technology, and in particular to a voice-controlled intelligent foldable nap bed and a control method thereof. Background Art

[0002] The foldable nap bed is mainly used for naps because of its easy folding characteristics that it can be opened and folded. As for the nap beds for kindergarten children, due to the large number of children in the kindergarten, teachers need to spend a lot of time every day to move, place and store them, which is a lot of physical work. In addition, there are certain safety hazards when placing the movable storage bed in the kindergarten classroom. In order to reduce the workload of teachers and effectively solve the safety of product use, how to provide a nap bed that can reduce the workload of teachers and improve the safety of use under the premise of existing functions and sizes has practical application value and significance. Summary of the invention

[0003] In order to provide a nap bed that can reduce the teacher's workload and improve the safety of use under the premise of existing functions and dimensions, the present application provides a voice-controlled intelligent folding and storage nap bed and a control method thereof.

[0004] In the first aspect, the invention objective of the present application is achieved by adopting the following technical solutions:

[0005] A voice-controlled intelligent folding and storage-type nap bed, comprising: a storage cabinet and a bed body, a storage drive component for driving the bed body to reciprocate relative to the storage cabinet to be in a folded state or an unfolded state is arranged between the storage cabinet and the bed body, the storage drive component is connected to a voice control component for controlling the opening and closing of the storage drive component, and the voice control component controls the storage drive component to open and execute bed body unfolding or bed body storage operation based on the acquired voice information instruction;

[0006] The nap bed also includes an infrared sensing module arranged in the storage activity range of the bed body. The infrared sensing module is used to sense whether there is a person within the storage activity range of the bed body when the storage drive component drives the bed body to move. When the infrared sensing module senses that a person is within the storage activity range of the bed body, it outputs a safety prompt message and controls the storage drive component to stop moving the bed body.

[0007] By adopting the above technical scheme, the present application provides a voice-controlled intelligent foldable and retractable nap bed. In the application context of kindergartens, since a large number of nap beds need to be placed for young children and young children may walk around at will after a nap, it is also necessary to pay attention to personnel safety issues when storing the bed to reduce accidental bumps. Therefore, the present application is not only provided with a storage drive component for intelligently controlling the bed to repeatedly move and switch between a folded state and an unfolded state, but in the unfolded state, the nap bed can be used normally, and in the folded state, the bed is stored in a storage cabinet to reduce the space occupied by the bed. The teacher only needs to input voice information instructions (such as bed folding instructions, bed storage instructions) through the voice control component to intelligently control the storage drive component to drive the bed to switch between the folded state and the unfolded state. The foldable bed can be switched between a folded state and an unfolded state, which helps to reduce the teacher's workload and makes the bed placement more efficient. In order to further improve the safety of the foldable nap bed, when the storage drive component drives the bed to move, an infrared sensing module is also provided for sensing whether there is a person within the storage activity range of the bed when the storage drive component drives the bed to move. When no person is sensed to be within the storage activity range of the bed, the bed is stored or unfolded normally. When a person is sensed to be within the storage activity range of the bed, the storage drive component controls the bed to stop moving and outputs a safety prompt message. Thus, the present application achieves the purpose of providing a nap bed that can reduce the teacher's workload and improve the safety of use under the premise of existing functions and dimensions.

[0008] In a preferred example of the present application: multiple beds are arranged side by side, and a support frame is provided at the bottom of the multiple beds, and one end of the support frame is hinged to the inner wall of the storage cabinet; the storage drive component includes a pneumatic telescopic rod and a drive motor, one end of the pneumatic telescopic rod is rotatably connected to the support frame, and the other end of the pneumatic telescopic rod is rotatably connected to the side wall of the storage cabinet, one end of the drive motor is rotatably connected to the support frame, and the other end of the pneumatic telescopic rod is rotatably connected to the side wall of the storage cabinet; the voice control component includes a control button for controlling the voice control component to be turned on and off.

[0009] By adopting the above technical solution, in actual application, in order to achieve efficient utilization of space, multiple beds are usually arranged side by side to accommodate more children in the same classroom; further, the driving motor drives the extension and retraction of the pneumatic telescopic rod to control the supporting force and up and down speed of the nap bed, so as to complete the unfolding, folding and storage of the nap bed in an intelligent and automatic manner; at the same time, the control button of the voice control component can effectively reduce the situation where the voice control component is accidentally touched by the child's voice when the nap bed is in use, which poses a safety hazard. Therefore, the control button can be used to control the voice control component to be turned off after the nap bed is placed according to the nap time interval, and the voice control component can be turned on after the nap time to complete the folding and storage of the nap bed, thereby further improving the safety of the nap bed.

[0010] In a preferred example of the present application: it also includes a sliding guide rail, and there are multiple beds, and the multiple beds are all slidably set on the sliding guide rails. The sizes of the multiple beds are gradually reduced along the length direction of the sliding guide rails. When the multiple beds are moved to a folded state, the larger size of two adjacent beds is overlapped on top of the other bed; a pulley is also provided at the bottom of each bed.

[0011] By adopting the above-mentioned technical solution, the present application provides another embodiment of a nap bed, which is stacked layer by layer and gradually becomes smaller on a sliding guide rail to provide a modular nap bed that is easy to store and fold, which is beneficial to saving the space occupied by the nap bed when not in use, and the pulley at the bottom facilitates the movement of the entire nap bed.

[0012] In a preferred example of the present application: the infrared sensing module includes a plurality of infrared sensing units spaced apart in the placement area of ​​the nap bed, and the infrared light emitted by the plurality of infrared sensing units forms a virtual detection frame on the ground of the nap bed, and the virtual detection frame is adapted to the placement area of ​​the nap bed.

[0013] By adopting the above technical solution, the infrared light emitted by multiple infrared sensing units forms a virtual detection frame, so as to sense in real time whether there is a person within the storage activity range of the bed when the storage drive component performs the bed expansion or bed storage operation, so as to facilitate the teacher to perform the bed expansion and storage work. Infrared light is harmless to young children. In actual use, the infrared sensing method of far-infrared light can achieve the purpose of infrared sensing the real-time standing position of the person and prevent the far-infrared light from causing additional harm to the person, thereby improving the intelligent control and use safety of the nap bed.

[0014] In the second aspect, the invention objective of the present application is achieved by adopting the following technical solutions:

[0015] A control method based on a voice-controlled intelligent folding and storing nap bed is applied to the voice-controlled intelligent folding and storing nap bed as described above, and the method comprises:

[0016] Acquiring a voice information instruction through the voice control component, and controlling the storage drive component to start and perform a bed unfolding operation or a bed folding operation based on the voice information instruction;

[0017] When the storage drive component is in the on state, an infrared sensing signal of the infrared sensing module is obtained; the infrared sensing signal is compared with a preset infrared sensing threshold signal to sense whether a person is within the storage activity range of the bed when the storage drive component drives the bed to move;

[0018] When the infrared sensing signal is less than a preset infrared sensing threshold signal, a safety prompt message is output, and the storage drive component is controlled to stop moving the bed.

[0019] By adopting the above technical solution, in the application context of kindergartens, since there are a large number of nap beds that need to be placed for young children and young children may walk around at will after taking a nap, etc., it is also necessary to pay attention to personnel safety issues when storing the bed to reduce accidental bumps. Therefore, the present application is not only provided with a storage drive component for intelligently controlling the bed to repeatedly move and switch between a folded state and an unfolded state, but also, in the unfolded state, the nap bed can be used normally, and in the folded state, the bed is stored in the storage cabinet to reduce the space occupied by the bed. The teacher only needs to input voice information instructions (such as bed folding instructions, bed storage instructions) through the voice control component to intelligently control the storage drive component to drive the bed to switch between a folded state or an unfolded state. state, which is conducive to reducing the workload of teachers and the efficiency of placing the bed is higher; and in order to further improve the safety of the foldable and foldable nap bed, when the storage drive component drives the bed to move, an infrared sensing module is also provided for sensing whether there is a person within the storage activity range of the bed when the storage drive component drives the bed to move. When no person is sensed to be within the storage activity range of the bed, the bed is stored or unfolded normally. When a person is sensed to be within the storage activity range of the bed, the storage drive component controls the bed to stop moving and outputs a safety prompt message. Therefore, the present application achieves the purpose of providing a nap bed that can reduce the workload of teachers and improve the safety of use under the premise of existing functions and dimensions.

[0020] In a preferred example of the present application: a plurality of nap beds are provided, the infrared sensing module includes a plurality of infrared sensing units for forming a virtual detection frame on the ground of the nap beds, and the method further includes:

[0021] A bed activity area frame is arranged on the ground of the nap bed through an indicator light bar, the bed activity area frame is adapted to the virtual detection frame, and the cross-sectional area of ​​the virtual detection frame is larger than the cross-sectional area of ​​the bed activity area frame; the bed activity area frame is associated with a bed identifier;

[0022] When the infrared sensing signal is less than a preset infrared sensing threshold signal, the indicator light bar is controlled to be in an abnormal prompt state, and abnormal prompt information is output to a preset voice-controlled user terminal based on the bed identification.

[0023] By adopting the above technical solution, the bed activity area frame is laid out on the ground through indicator light strips, which is conducive to the arrangement of children to quickly find their arranged location for nap, saving children's searching time; at the same time, in actual application, setting the virtual detection frame to be slightly larger than the bed activity area frame is also conducive to early detection of whether there are people who are about to enter the storage and activity range of the bed, thereby improving the detection and prompt safety performance. The voice-controlled user terminal is a remote intelligent terminal, and teachers can control the voice control components of multiple nap beds through the voice-controlled user terminal, which is conducive to improving teachers' monitoring effect on the status of multiple nap beds and improving control efficiency.

[0024] In a preferred example of the present application: the method further includes:

[0025] When the storage drive component is turned on to perform the bed unfolding or bed folding operation, a current detection signal of the storage drive component is obtained, and the indicator light bar is controlled to be in an active prompt state;

[0026] The current detection signal is compared with a preset current detection threshold value, and when the current detection signal is less than the preset current detection threshold value, a driving abnormality prompt signal is output to the preset voice-controlled user terminal based on the bed identification, and the corresponding indicator light bar is controlled to be in a driving abnormality prompt state;

[0027] Based on the acquired color differentiation display instruction of the preset voice-controlled user terminal, the corresponding indicator light bar is controlled to display the corresponding color state.

[0028] By adopting the above technical solution, by obtaining the current detection signal of the storage drive component and comparing it with the current detection threshold, it is determined whether the storage drive component has an abnormal operation or fault during a long-term operation; when it is detected that the current detection signal is less than the current detection threshold, it indicates that the storage drive component has an abnormal situation of short circuit or open circuit. At this time, the abnormal driving prompt signal is used to give an abnormal prompt to the teacher connected to the voice-controlled user terminal, and the corresponding indicator light bar is controlled to be in the driving abnormal prompt state, so as to remind the children to pay attention to safety and find the faulty nap bed among many nap beds, which is convenient to operate; further, in order to facilitate the children to find their own nap position, after the nap bed is unfolded, the teacher can control multiple adjacent nap beds to display in different colors through the voice-controlled user terminal, so that the children can quickly find their own nap bed position according to the color, saving the time of finding the nap bed position, improving the work efficiency of the teacher, and assisting the children to find their own nap bed position in a simple and easy-to-understand way, which has high application value.

[0029] In a preferred example of the present application: the inner side wall of the storage cabinet is provided with a distance measuring module for measuring the distance between the bed and the storage cabinet during the movement of the bed; the method further includes:

[0030] When the storage drive assembly is turned on to perform the bed unfolding operation, the distance between the bed and the storage cabinet is obtained multiple times by the distance measurement module to obtain different unfolding distance measurement data;

[0031] When the storage drive assembly is turned on to perform the bed folding operation, the distance between the bed and the storage cabinet is obtained multiple times by the distance measurement module to obtain different folding distance measurement data;

[0032] Associating different unfolded ranging data and different folded ranging data with corresponding time nodes and sending them to a preset fault judgment model, identifying and obtaining the distance threshold intervals corresponding to the unfolded ranging data and the folded ranging data;

[0033] Comparing the different unfolded distance measurement data with the corresponding distance threshold interval to obtain a corresponding unfolded distance measurement judgment result, and comparing the different folded distance measurement data with the corresponding distance threshold interval to obtain a corresponding folded distance measurement judgment result;

[0034] When the unfolded ranging judgment result meets the preset fault judgment condition, or when the folded ranging judgment result meets the preset fault judgment condition, fault warning information is generated based on the corresponding bed identification and sent to the preset voice control user terminal.

[0035] By adopting the above technical solution, the bed unfolding effect and bed folding effect of the storage drive component are detected in real time through the distance measurement module, so as to timely discover and issue abnormal prompts when the bed unfolds or the bed folds abnormally. Specifically, during the unfolding of the bed, under normal circumstances, the distance between the bed and the active end of the storage cabinet gradually increases. In this process, multiple unfolding distance measurement data are obtained, and each unfolding distance measurement data is compared with the distance threshold interval of the corresponding time node to determine whether the bed is unfolded normally, and the corresponding unfolding distance measurement judgment result is obtained. When the storage drive component is abnormal, the distance of the bed is at a certain detection time. The distance between the nodes may appear abnormally large or abnormally small; by the same token, during the storage process of the bed, under normal circumstances, the distance between the bed and the active end of the storage cabinet gradually decreases. During this process, multiple folding distance measurement data are obtained, and the multiple folding distance measurement data are compared based on the distance threshold interval of the corresponding time node to determine whether the bed is folded and stored normally, and the corresponding folding distance measurement judgment result is obtained; when the unfolding distance measurement judgment result meets the fault judgment condition, it indicates that the bed is unfolded abnormally, and a fault warning information is sent to the voice-controlled user terminal based on the corresponding bed mark, so as to promptly provide a fault prompt and take fault handling measures.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. In actual application, in order to achieve efficient utilization of space, multiple beds are usually arranged side by side to accommodate more children in the same classroom; further, the driving motor drives the extension and retraction of the pneumatic telescopic rod to control the support force and up and down speed of the nap bed, so as to complete the unfolding, folding and storage of the nap bed in an intelligent and automatic manner; at the same time, the control button of the voice control component can effectively reduce the situation where the voice control component is accidentally touched by the voice of the child and causes the nap bed to be folded when there are people, which poses a safety hazard. Therefore, the control button can be used to control the voice control component to be turned off according to the nap time interval after the nap bed is placed, and the voice control component is turned on after the nap time is over to complete the folding and storage of the nap bed, thereby further improving the safety of the nap bed;

[0038] 2. The method of laying out the bed activity area frame on the ground through the indicator light bar is conducive to the arrangement of children to quickly find their arranged location for nap, saving children's searching time; at the same time, in actual application, setting the virtual detection frame to be slightly larger than the bed activity area frame is also conducive to early detection of whether there are people who are about to enter the storage activity range of the bed, improving the detection and prompting safety performance. The voice-controlled user terminal is a remote intelligent terminal. Teachers can control the voice control components of multiple nap beds through the voice-controlled user terminal, which is conducive to improving the status monitoring effect of multiple nap beds by teachers and improving control efficiency;

[0039] 3. The bed unfolding effect and bed folding effect of the storage drive component are detected in real time through the distance measurement module, so as to timely discover and give abnormal prompts when the bed unfolds or the bed folds abnormally. Specifically, during the unfolding of the bed, under normal circumstances, the distance between the bed and the active end of the storage cabinet gradually increases. In this process, multiple unfolding distance measurement data are obtained, and each unfolding distance measurement data is compared with the distance threshold interval of the corresponding time node to determine whether the bed is unfolded normally and obtain the corresponding unfolding distance measurement judgment result. When the storage drive component is abnormal, the distance of the bed at a certain detection time node will be It presents an abnormally large or abnormally small phenomenon; by the same token, during the storage process of the bed, under normal circumstances, the distance between the bed and the active end of the storage cabinet gradually becomes smaller, and multiple folding distance measurement data are obtained in this process, and the multiple folding distance measurement data are compared based on the distance threshold interval of the corresponding time node to determine whether the bed is folded and stored normally, and the corresponding folding distance measurement judgment result is obtained; when the unfolding distance measurement judgment result meets the fault judgment condition, it indicates that the bed is unfolded abnormally, and a fault warning information is sent to the voice-controlled user terminal based on the corresponding bed mark, so as to promptly issue a fault prompt and take fault handling measures.

The storage cabinet 1 is an integrated storage cabinet 1 fixedly arranged on the ground, and a plurality of bed bodies 2 are arranged side by side. A support frame 21 is arranged at the bottom of the plurality of bed bodies 2, and one end of the support frame 21 is hinged to the inner wall of the storage cabinet 1; in this embodiment, four bed bodies 2 are arranged on one support frame 21 as an example, and a storage drive component 3 for driving the bed body 2 to reciprocate relative to the storage cabinet 1 to be in a folded state or an unfolded state is arranged between the storage cabinet 1 and the bed body 2, and the storage drive component 3 is connected to a storage drive component for controlling the storage drive component 3. The voice control component 4 is turned on and off by the component 3. The voice control component 4 is an intelligent terminal device that is controlled based on voice commands. The voice control component 4 controls the storage drive component 3 to start and execute the bed body 2 unfolding or bed body 2 storage operation based on the acquired voice information command. The voice control component 4 includes a control button for controlling the voice control component 4 to start and stop. The control button can be used according to the nap time interval. After the nap bed is placed, the voice control component 4 can be controlled to be turned off. After the nap time, the voice control component 4 can be controlled to start to complete the folding and storage of the nap bed, thereby further improving the safety of the nap bed.

[0052] like Figure 1 and Figure 2As shown, the nap bed also includes an infrared sensing module arranged in the storage activity range of the bed body 2. The infrared sensing module is used to sense whether there is a person within the storage activity range of the bed body 2 when the storage drive component 3 drives the bed body 2 to move. When the infrared sensing module senses that there is a person within the storage activity range of the bed body 2, it outputs a safety prompt message and controls the storage drive component 3 to stop moving the bed body 2. The nap bed is used normally in the unfolded state. In the folded state, the bed body 2 is stored in the storage cabinet 1 to reduce the space occupied by the bed body 2. The teacher only needs to input voice information instructions (such as bed folding instructions, bed storage instructions) through the voice control component 4, that is, The storage drive component 3 can be intelligently controlled to drive the bed body 2 to switch between a folded state and an unfolded state, which is beneficial to reducing the workload of teachers and making the placement of the bed body 2 more efficient; and when the storage drive component 3 drives the bed body 2 to move, when the infrared sensing module does not sense that a person is within the storage activity range of the bed body 2, the bed body 2 is normally stored or unfolded. When the infrared sensing module senses that a person is within the storage activity range of the bed body 2, the storage drive component 3 controls the bed body 2 to stop moving and outputs a safety prompt message. Thus, the present application achieves the purpose of providing a nap bed that can reduce the workload of teachers and improve the safety of use under the premise of existing functions and dimensions.

[0053] like Figure 1 and Figure 2 As shown, the storage drive assembly 3 includes a pneumatic telescopic rod 31 and a drive motor 32. One end of the pneumatic telescopic rod 31 is rotatably connected to the support frame 21, and the other end of the pneumatic telescopic rod 31 is rotatably connected to the side wall of the storage cabinet 1. One end of the drive motor 32 is rotatably connected to the support frame 21, and the other end of the pneumatic telescopic rod 31 is rotatably connected to the side wall of the storage cabinet 1; the drive motor 32 drives the extension and retraction of the pneumatic telescopic rod 31, controls the supporting force and the up and down speed of the nap bed, and completes the unfolding, folding and storage work of the nap bed in an intelligent and automated manner.

[0054] In practical application, the infrared sensing module can be an infrared human body sensor installed at the top of the storage cabinet 1, or Figure 3As shown, the infrared sensing module also includes a plurality of infrared sensing units (the infrared sensing units are not shown in the figure) which are spaced apart and distributed in the placement area of ​​the nap bed. The infrared light emitted by the plurality of infrared sensing units forms a virtual detection frame on the ground of the nap bed. The virtual detection frame is adapted to the placement area of ​​the nap bed. In actual application, it also includes a top plate (not shown in the figure) arranged on the top of the nap bed. The infrared sensing unit includes an infrared radiation unit and an infrared receiving unit which are symmetrically arranged. The infrared radiation unit is arranged on the top plate, and the infrared receiving unit is arranged on the ground of the nap bed. Alternatively, the infrared radiation unit is arranged on the top plate of the nap bed. The ground of the bed is provided with an infrared receiving unit on the top plate, so that the infrared light emitted by multiple infrared sensing units forms a virtual detection frame, so as to sense in real time whether there is a person within the storage activity range of the bed body 2 when the storage drive component 3 performs the operation of unfolding the bed body 2 or folding the bed body 2, so as to facilitate the teacher to unfold and fold the bed body 2, and the infrared light is harmless to young children. In actual use, the infrared sensing method of far-infrared light can achieve the purpose of infrared sensing the real-time standing position of the person and prevent the far-infrared light from causing additional harm to the person, thereby improving the intelligent control and use safety of the nap bed.

[0055] The implementation principle of a voice-controlled intelligent foldable nap bed in the embodiment of the present application is as follows: the present application is not only provided with a storage drive component 3 for intelligently controlling the bed body 2 to repeatedly move and switch between a folded state and an unfolded state, but also when in the unfolded state, the nap bed can be used normally, and when in the folded state, the bed body 2 is stored in the storage cabinet 1, reducing the space occupied by the bed body 2. The teacher only needs to input voice information instructions (such as bed folding instructions, bed storage instructions) through the voice control component 4 to intelligently control the storage drive component 3 to drive the bed body 2 to switch between a folded state and an unfolded state, which is conducive to reducing the teacher's workload and the efficiency of placing the bed body 2 is higher. In addition, the present application is further In order to improve the safety of the foldable nap bed, when the storage drive component 3 drives the bed body 2 to move, an infrared sensing module is also provided for sensing whether a person is within the storage activity range of the bed body 2 when the storage drive component 3 drives the bed body 2 to move. When no person is sensed to be within the storage activity range of the bed body 2, the bed body 2 is stored or unfolded normally. When a person is sensed to be within the storage activity range of the bed body 2, the storage drive component 3 controls the bed body 2 to stop moving and outputs a safety prompt message. Thus, the present application achieves the purpose of providing a nap bed that can reduce the teacher's workload and improve the safety of use under the premise of existing functions and dimensions.

[0056] Example 2

[0057] Reference Figure 4, the embodiment of the present application is different from the embodiment 1 in that: the nap bed also includes a sliding rail, and four bed modules are used as an example for explanation. For the convenience of distinction, they are marked with 101, 102, 103, and 104 in the figure. Multiple bed bodies are slidably arranged on the sliding rail, and the sliding rail is a three-section rail 104 in the figure; the sizes of the multiple bed bodies are gradually reduced along the length direction of the sliding rail. When the multiple bed bodies move in a folded state, the larger size of the two adjacent bed bodies is overlapped on top of the other bed body; a pulley is also provided at the bottom of each bed body; ( Figure 5 The installation diagram of the storage cabinet is omitted in the figure. When the present embodiment is actually applied, the installation of the storage cabinet can be omitted according to one's own needs); the present embodiment provides a modular nap bed that is easy to store and fold by stacking layers and gradually getting smaller on the sliding guide rail, which is beneficial to saving the space occupied by the nap bed when not in use, and the pulley at the bottom facilitates the movement of the entire nap bed.

[0058] In one embodiment, a control method for a voice-controlled intelligent foldable nap bed is provided. The control method for a voice-controlled intelligent foldable nap bed is applied to a voice-controlled intelligent foldable nap bed as described above.

[0059] like Figure 5 As shown, a control method of a voice-controlled intelligent folding and storage nap bed comprises:

[0060] S1: Acquire voice information instructions through the voice control component, and control the storage drive component to start and execute the bed expansion operation or storage operation based on the voice information instructions.

[0061] In this embodiment, when in the unfolded state, the nap bed can be used normally, and when in the folded state, the bed is stored in the storage cabinet to reduce the space occupied by the bed. The teacher only needs to input voice information instructions (such as bed folding instructions, bed storage instructions) through the voice control component to intelligently control the storage drive component to drive the bed to switch between the folded state and the unfolded state, which is conducive to reducing the teacher's workload and making the bed placement more efficient.

[0062] S2: When the storage drive component is in the on state, an infrared sensing signal of the infrared sensing module is obtained; the infrared sensing signal is compared with a preset infrared sensing threshold signal to sense whether a person is within the storage activity range of the bed when the storage drive component drives the bed to move.

[0063] S3: When the infrared sensing signal is less than a preset infrared sensing threshold signal, a safety prompt message is output, and the storage drive component is controlled to stop moving the bed.

[0064] In this embodiment, when the infrared sensing module does not sense that a person is within the storage and activity range of the bed, the bed is stored or unfolded normally. When it senses that a person is within the storage and activity range of the bed, the storage drive component controls the bed to stop moving and outputs a safety prompt message. Thus, this application achieves the purpose of providing a nap bed that can reduce the teacher's workload and improve the safety of use under the premise of existing functions and dimensions.

[0065] In one embodiment, a plurality of nap beds are provided, and the infrared sensing module includes a plurality of infrared sensing units for forming a virtual detection frame on the ground of the nap bed. A control method based on a voice-controlled intelligent foldable nap bed also includes:

[0066] S11: a bed activity area frame is arranged on the ground of the nap bed through an indicator light bar, the bed activity area frame is adapted to the virtual detection frame, and a cross-sectional area of ​​the virtual detection frame is larger than a cross-sectional area of ​​the bed activity area frame; and the bed activity area frame is associated with a bed identifier.

[0067] In this embodiment, the bed activity area frame is located within the virtual detection frame.

[0068] Specifically, the method of laying out the bed activity area frame on the ground through the indicator light strip is conducive to the arrangement of young children to quickly find their arranged positions for naps, saving the children's searching time.

[0069] S12: When the infrared sensing signal is less than a preset infrared sensing threshold signal, the control indicator light bar is in an abnormal prompt state, and an abnormal prompt information is output to a preset voice control user terminal based on the bed identification.

[0070] In this embodiment, setting the virtual detection frame to be slightly larger than the bed activity area frame is also beneficial for detecting in advance whether there are people who are about to enter the storage and activity range of the bed, thereby improving the detection and prompt safety performance. The voice-controlled user terminal is a remote intelligent terminal, and the teacher can control the voice control components of multiple nap beds through the voice-controlled user terminal, which is beneficial for improving the teacher's status monitoring effect of multiple nap beds and improving control efficiency.

[0071] In one embodiment, if Figure 6 As shown, a control method based on voice-controlled intelligent folding and storage nap bed also includes:

[0072] S111: When the storage drive component is turned on to perform the bed unfolding or bed storage operation, a current detection signal of the storage drive component is obtained, and the indicator light bar is controlled to be in an active prompt state.

[0073] Specifically, by obtaining the current detection signal of the storage drive component and comparing it with the current detection threshold, it is determined whether the storage drive component has an operation abnormality or failure during a long-term operation.

[0074] S112: Compare the current detection signal with a preset current detection threshold. When the current detection signal is less than the preset current detection threshold, output a drive abnormality prompt signal to a preset voice-controlled user terminal based on the bed identification, and control the corresponding indicator light bar to be in a drive abnormality prompt state.

[0075] Specifically, when it is detected that the current detection signal is less than the current detection threshold, it indicates that a short circuit or open circuit occurs in the sensor drive component. At this time, the teacher connected to the voice-controlled user terminal is prompted with an abnormality through a driving abnormality prompt signal, and the corresponding indicator light bar is controlled to be in a driving abnormality prompt state; so as to remind the children to pay attention to safety and find the faulty nap bed among many nap beds, which is more convenient to operate.

[0076] S113: Based on the acquired preset color differentiation display instruction of the voice-controlled user terminal, control the corresponding indicator light bar to display the corresponding color state.

[0077] In this embodiment, in order to facilitate young children to find their own nap positions, after the nap beds are unfolded, the teacher can control multiple adjacent nap beds to display in different colors through the voice-controlled user terminal, so that young children can quickly find their own nap beds according to the colors, saving time in finding the nap bed positions, improving the work efficiency of teachers, and assisting young children to find their own nap beds in a simple and easy-to-understand way, which has a high application value.

[0078] In one embodiment, if Figure 7 As shown, the inner wall of the storage cabinet is provided with a distance measuring module for measuring the distance between the bed and the storage cabinet during the activity of the bed; a control method based on a voice-controlled intelligent folding storage nap bed also includes:

[0079] S10: When the storage drive assembly is turned on to perform the bed unfolding operation, the distance between the bed and the storage cabinet is obtained multiple times through the distance measurement module to obtain different unfolding distance measurement data.

[0080] In this embodiment, the distance measuring module is a distance measuring sensor, and two distance measuring sensors are provided and respectively installed at the top and the middle of the inner wall of the storage cabinet.

[0081] Specifically, in the same bed deployment operation, the distance measurement sensors in the middle and the top collect data at least twice to obtain deployment distance measurement data based on different time nodes.

[0082] S20: When the storage drive component is turned on to perform the bed folding operation, the distance between the bed and the storage cabinet is obtained multiple times through the distance measurement module to obtain different folding distance measurement data.

[0083] Specifically, in the same bed folding operation, the ranging sensors in the middle and the top collect data at least twice to obtain folding ranging data based on different time nodes.

[0084] S30: Associating different unfolded ranging data and different folded ranging data with corresponding time nodes and sending them to a preset fault judgment model, identifying and obtaining distance threshold intervals corresponding to the unfolded ranging data and the folded ranging data.

[0085] Specifically, the preset fault judgment model pre-stores corresponding distance threshold intervals for different time nodes, and the time node starts timing when the voice control command is received. For example, in the unfolded state, at the 3rd second, the distance threshold interval corresponding to the middle ranging sensor is 30-40 cm, and the distance threshold interval corresponding to the top ranging sensor is 70-80 cm; the designer can obtain the distance threshold intervals corresponding to the unfolded ranging data and the folded ranging data according to the custom settings of the ranging distance obtained by measuring the nap bed in a normal state, and pre-store them in the fault judgment model for comparison.

[0086] S40: Compare different unfolded distance measurement data with corresponding distance threshold intervals to obtain corresponding unfolded distance measurement judgment results, and compare different folded distance measurement data with corresponding distance threshold intervals to obtain corresponding folded distance measurement judgment results.

[0087] S50: When the unfolded ranging judgment result meets the preset fault judgment condition, or when the folded ranging judgment result meets the preset fault judgment condition, a fault warning message is generated based on the corresponding bed identification and sent to the preset voice control user terminal.

[0088] In this embodiment, when the unfolded ranging judgment result meets the preset fault judgment condition, that is, the unfolded ranging data is not within the corresponding distance threshold interval; when the folded ranging judgment result meets the preset fault judgment condition, that is, the folded ranging data is not within the corresponding distance threshold interval.

[0089] Specifically, during the unfolding of the bed, under normal circumstances, the distance between the active end of the bed and the storage cabinet gradually increases. During this process, multiple unfolding distance measurement data are obtained, and each unfolding distance measurement data is compared with the distance threshold interval of the corresponding time node to determine whether the bed is normally unfolded, and the corresponding unfolding distance measurement judgment result is obtained. When the storage drive component is abnormal, the distance of the bed at a certain detection time node will be abnormally large or abnormally small; similarly, during the storage of the bed, under normal circumstances, the distance between the active end of the bed and the storage cabinet gradually decreases. During this process, multiple folding distance measurement data are obtained, and the multiple folding distance measurement data are compared based on the distance threshold interval of the corresponding time node to determine whether the bed is normally folded and stored, and the corresponding folding distance measurement judgment result is obtained; when the unfolding distance measurement judgment result meets the fault judgment condition, it indicates that the bed is abnormally unfolded, and a fault warning information is sent to the voice-controlled user terminal based on the corresponding bed position identification, so as to promptly issue a fault prompt and take fault handling measures.
