Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an interconnection control method, device and air conditioner for an air conditioner and an assisted bed for getting up and lying down. Background Technology

[0002] With the continuous development of an aging population, and the increasing mobility issues caused by various factors (such as slow movement and cognitive decline), intelligent adjustable beds have emerged to assist the elderly in getting up and down. When an elderly person is prone to sleep, the bed surface can gradually flatten as they slowly lie down. After the elderly person wakes up, the bed surface is immediately raised to help them lean back or get up.

[0003] Under this premise, the elderly have increasingly higher requirements for the additional functions of everyday household appliances, and their requirements for air conditioning technology are no exception. In addition to the most basic cooling and heating functions, current air conditioners and lifting beds that assist the elderly in getting up and lying down cannot be effectively interconnected and cannot be intelligently adjusted according to each other's actual conditions. As a result, even after the elderly have already lay down with the assistance of the lifting bed, they still need to spend effort to find the air conditioner remote control to adjust the air conditioner's operating mode, resulting in a poor user experience for the elderly user group. Summary of the Invention

[0004] This invention provides an interconnection control method, device, and air conditioner for an air conditioner and an assisted bed-raising and lowering bed, which solves the problem in the prior art where users need to manually adjust the parameters of the air conditioner and the assisted bed-raising and lowering bed that are connected to each other, resulting in poor control accuracy and efficiency.

[0006] Based on the head position detected by the radar module for each individual, the lower boundary of the default swing range of the horizontal guide plate assembly is updated to the target execution angle.

[0007] During the process of controlling the horizontal guide plate assembly to swing up and down within the new swing zone, the radar module monitors the key points of each individual to determine the user's behavioral intention.

[0008] If the user's behavioral intention matches the trend of getting up, the first bed control command controls the movable bed to rotate clockwise by an auxiliary angle change value corresponding to the target range, based on the target range of the angle between the individual's upper body and the movable bed board collected by the radar module, so as to assist the individual in getting up.

[0009] The target execution angle is greater than the included angle formed by the head position of the individual and the vertical direction of the radar module; the target interval is one of all included angle subintervals between the upper body of the elderly and the movable bed board during the process of executing the getting-up action; and any of the included angle subintervals is respectively provided with an auxiliary angle change value of the rotation of the movable bed board relative to the fixed bed board.

[0012] If the included angle formed by the first trunk segment and the second trunk segment at the hip key point decreases from 180° over time within a preset time length, the user behavior intention is set as a getting-up trend;

[0028] If it is determined that the included angle between the upper body of the individual and the movable bed plate is reduced to a first threshold value and maintained at a state smaller than the first threshold value and larger than a second threshold value within a preset time length, the counterclockwise rotation of the movable bed plate is stopped through the fourth bed body control instruction, so that the individual leans on the movable bed plate fixed in the lowering process with the upper body.

[0029] If it is determined that the included angle between the upper body of the individual and the movable bed plate is reduced to a first threshold value and continues to reduce to 0 within a preset time length, the counterclockwise rotation of the movable bed plate is reset through the fourth bed body control instruction, so that the individual lies down along with the movable bed plate in a state that the included angle between the upper body and the movable bed plate is 0.

As used in this application, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0053] Figure 1 is one of the flow schematic diagrams of the interconnection control method of the air conditioner and the auxiliary getting-out-of-bed bed provided by the application. As shown in Figure 1 The interconnection control method of the air conditioner and the auxiliary getting-out-of-bed bed provided by the embodiment of the application, wherein the air conditioner and the auxiliary getting-out-of-bed bed are arranged in the same indoor environment, the auxiliary getting-out-of-bed bed is provided with a fixed bed plate and a movable bed plate rotating relative to the fixed bed plate, comprises the following steps: 101, updating the lower boundary of the default swing range of the horizontal guide plate assembly to a target execution angle based on the head position of each individual monitored by the radar module.

[0054] The target execution angle is greater than the included angle formed by the head position of the individual and the vertical direction of the radar module.

[0055] It should be noted that the execution subject of the interconnection control method of the air conditioner and the auxiliary getting-out-of-bed bed provided by the embodiment of the application is the interconnection control device of the air conditioner and the auxiliary getting-out-of-bed bed.

[0056] The application scenario of the interconnection control method of the air conditioner and the auxiliary getting-out-of-bed bed provided by the embodiment of the application is that the air conditioner and the auxiliary getting-out-of-bed bed are in the same indoor environment and are connected in communication by the same local area network. When the user activates the air conditioner, the behavior intention of the individual is determined through the contour information fed back by the radar module in real time, and the air supply mode of the air conditioner and the lifting of the auxiliary getting-out-of-bed bed are adjusted accordingly.

[0057] The auxiliary getting-up-and-lying bed is mainly used for the disabled, the elderly and other vulnerable groups. The auxiliary getting-up-and-lying bed comprises a hinged movable bed board and a fixed bed board. The movable bed board is supported by a pneumatic device below and is driven by a controlled instruction to change the included angle of the movable bed board and the fixed bed board at the hinge, so as to realize the lifting of the movable bed board. That is, when the included angle of the movable bed board and the fixed bed board at the hinge gradually increases to 180°, the movable bed board of the auxiliary getting-up-and-lying bed gradually descends until it is completely flattened to assist the user to lie down and sleep. When the included angle of the movable bed board and the fixed bed board at the hinge gradually decreases from 180°, the movable bed board of the auxiliary getting-up-and-lying bed gradually rises until it is completely lifted to assist the user to get up, to lean or sit.

[0058] In addition, the radar module is arranged on the air conditioner, periodically collects all individuals in the indoor space at a specified time interval, and sends the spatial distribution position of each individual to the interconnection control device of the air conditioner and the auxiliary getting-up-and-lying bed. The working period of the radar module is not limited in the embodiment of the present application.

[0059] Optionally, the radar module can perform the collection operation at a default working period.

[0060] Optionally, the user can change the working period of the radar module by issuing a period change instruction, and the radar module receives and responds to the instruction to change the working period to the period indicated by the instruction for the collection operation.

[0061] It should be noted that before step 101, the user needs to send an activation instruction through a transmission medium to activate the working mode of the air conditioner, so that the indoor unit of the air conditioner operates at the default wind speed in the mode, and the outdoor unit operates at the default frequency in the mode.

[0062] Optionally, the user can transmit the activation instruction by using a wireless communication mode between the control device and the air conditioning system through the control device to initialize the working mode of the air conditioning system and start the radar module.

[0063] Optionally, the user can issue the activation instruction through voice interaction, and the air conditioning system receives the activation instruction, performs voice recognition, initializes the working mode, and starts the radar module.

[0064] Specifically, in step 101, after the air conditioner starts the working mode, the interconnection control device of the air conditioner and the auxiliary getting-up-and-lying bed receives the human feature information collected by the radar module in real time for each individual in the space where the air conditioner is located, extracts the position information corresponding to the head feature of each individual, calculates the included angle of the head position of the human body relative to the vertical line where the radar module is located, and continues to expand upward based on the included angle to obtain a target execution angle, so that the target execution angle is greater than the azimuth angle of the head of the human body.

[0065] Then, the target execution angle is packaged into an air conditioner control instruction and sent to the indoor unit, so that the yawing leaf assembly formed by the vertical arrangement of the plurality of guide vanes at the air outlet of the indoor unit updates the lower boundary of the original default swing range to the target execution angle obtained in step 101 while keeping the upper boundary of the default swing range unchanged, to form a new swing range.

[0066] Exemplarily, Figure 2 is one of the distribution maps of the air conditioner and the auxiliary getting-up-and-lying bed provided by the application. Figure 2 As shown, the new swing range is always above the head of the human body, and the air conditioner always swings above the head.

[0067] In step 102, the interconnection control device of the air conditioner and the auxiliary getting-up-and-lying bed determines the user behavior intention according to the position of the key points of the human body monitored by the radar module during the process in which the horizontal guide plate assembly swings up and down in the new swing range.

[0068] Specifically, in step 102, the interconnection control device of the air conditioner and the auxiliary getting-up-and-lying bed determines the user behavior intention according to the position of the key points of the human body monitored by the radar module during the process in which the horizontal guide plate assembly swings up and down in the new swing range.

[0069] The application does not specifically limit the type and number of radar sensing devices in the radar module.

[0070] Exemplarily, the radar module can include a laser radar, an infrared sensor, etc.

[0071] Optionally, the horizontal detection range of the millimeter wave radar can reach ±75°, the vertical detection range can reach ±40°, the maximum detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, the angle output accuracy can reach 1°, and it does not involve privacy issues and is not affected by light. Its response speed is also faster.

[0072] Therefore, the interconnection control device of the air conditioner and the auxiliary getting-up-and-lying bed parses the posture of the user individual according to the human feature information collected by the millimeter wave radar in real time.

[0073] Exemplarily, the radar module can include multiple types of sensing elements such as millimeter wave radars, laser radars, and infrared sensors, and the interconnection control device of the air conditioner and the auxiliary getting-up-and-lying bed integrates the human feature information collected by each sensing element to comprehensively depict the real-time posture of the individual.

[0074] For example, the individual's body feature information can be collected by using the millimeter wave radar, and the mapping relationship between the body feature information and the posture is fitted according to a large amount of prior data, so as to directly obtain the posture corresponding to the current body feature of the individual.

[0075] In step 103, when it is determined that the user behavior intention matches the getting-up trend, the active bed board is controlled to rotate clockwise by a first bed body control instruction according to a target interval in which an included angle between the upper body of the individual and the active bed board is located, and a supplementary angle change value corresponding to the target interval, so as to assist the individual to get up.

[0076] The target interval is one of all included angle subintervals between the upper body of the elderly and the active bed board during the process of performing the getting-up action. Any included angle subinterval is respectively provided with a supplementary angle change value of the active bed board relative to the fixed bed board.

[0077] It should be noted that, since the active bed board of the assisted getting-up and lying-down bed tracks the back of the individual in real time when performing the assistance task, the user individual subjectively pulls away the distance between the back and the active bed board, which means different behavior intentions.

[0078] For example, when the included angle between the upper body of the individual and the active bed board becomes smaller, it is considered that the individual needs to approach the active bed board for support, and when the included angle becomes larger, it is considered that the individual does not need to approach the active bed board and does not need the support.

[0079] Therefore, before step 103, N continuous included angle subintervals are divided between the upper limit and the lower limit of the included angle between the upper body of the individual and the active bed board under different behavior intentions, and the different included angle subintervals are quantified to distinguish the user intention.

[0080] Correspondingly, N supplementary angle change values corresponding to the rotation angle of the active bed board relative to the horizontal plane of the fixed bed board are also divided according to the N set included angle subintervals.

[0081] N is an integer greater than 1, and the interconnection control of the air conditioner and the assisted getting-up and lying-down bed can be evenly divided or custom divided between the upper limit and the lower limit of the included angle to obtain a plurality of included angle subintervals, which are not limited in the embodiments of the present application.

[0082] Specifically, in step 103, the interconnection control device of the air conditioner and the assisted getting-up and lying-down bed compares and queries the behavior intention corresponding to the posture corresponding to the body feature exhibited by the individual:

[0083] If the user behavior intention matches the getting-up trend, the radar module is used to collect the included angle between the upper body of the individual and the movable bed board, and the included angle sub-interval in which the current included angle is located is taken as the target interval, and the auxiliary angle change value corresponding to the included angle sub-interval is taken as the rotation angle to be executed by the auxiliary sit-to-stand bed in the current control.

[0084] Then, the auxiliary angle change value is packaged into the first bed body control instruction and sent to the auxiliary sit-to-stand bed, so that the auxiliary sit-to-stand bed rotates the movable bed board clockwise by the corresponding auxiliary angle change value on the basis of the current position, and provides auxiliary assistance for the getting-up action of the individual under different intentions in the process of lifting the movable bed board.

[0085] If the user behavior intention does not match the getting-up trend, no further processing is performed, and further analysis is required.

[0086] In the process of positioning the human body position by the radar module, the new execution angle of the horizontal swing leaf assembly is fitted according to the head position of the individual, so as to swing the air up and down above the head of the individual, and the user behavior intention is determined by the key point position of the human body monitored by the radar module. When the user behavior intention matches the getting-up trend, the target interval corresponding to the angle between the upper body of the individual and the movable bed board is determined, so that the auxiliary sit-to-stand bed is adjusted in combination with the auxiliary angle change value corresponding to the interval, to assist the individual to get up. When the air conditioner and the auxiliary sit-to-stand bed establish a communication relationship in the same local area network, the working states of the air conditioner and the auxiliary sit-to-stand bed are cooperatively controlled according to the posture change of the user, without the need for the user to manually adjust the parameters of the two intelligent devices respectively, the control time delay of the two intelligent devices is reduced, the control precision is improved, and the use experience of the user for the air conditioner and the auxiliary sit-to-stand bed is optimized.

[0087] On the basis of any of the above embodiments, the user behavior intention is determined by the radar module for the key point position of the human body monitored by each individual, including: determining the first trunk segment and the second trunk segment connected by the hip key point based on the key point position of the human body monitored by the radar module for each individual.

[0088] The first trunk segment is determined at least according to the head key point and the hip key point, and the second trunk segment is determined at least according to the hip key point and the foot key point.

[0089] Specifically, in step 102, the interconnection control device of the air conditioner and the auxiliary sit-to-stand bed segments the posture of the human body according to the distribution of the key point position of the human body monitored by each individual, to obtain the first trunk segment and the second trunk segment divided by the hip key point.

[0090] The first trunk segment is obtained by connecting the head key point, the crotch key point and other key points between the two in joint order after coordinate system conversion and standardization, and the posture of the upper body is output as the posture information of the upper body.

[0091] The second trunk segment is obtained by connecting the crotch key point, the foot key point and other key points between the two in joint order after coordinate system conversion and standardization, and the posture of the lower body is output as the posture information of the lower body.

[0092] If the included angle formed by the first trunk segment and the second trunk segment at the crotch key point decreases from 180 degrees over a preset time period, the user behavior intention is set as a getting-up trend.

[0093] If the included angle formed by the first trunk segment and the second trunk segment at the crotch key point is continuously maintained at 90 degrees over a preset time period, the user behavior intention is set as a lying-in-bed trend.

[0094] Specifically, the air conditioner and the auxiliary getting-up-and-lying-in-bed interconnection control device analyze the user behavior intention by using the relative position relationship of the crotch joint at the connection of the first trunk segment and the second trunk segment.

[0095] If the included angle formed by the first trunk segment and the second trunk segment at the crotch key point of any individual decreases from 180 degrees over a preset time period, it means that the user gradually gets up from the original lying posture, and the user behavior intention is set as a getting-up trend.

[0096] If the included angle formed by the first trunk segment and the second trunk segment at the crotch key point of any individual is always maintained at 90 degrees over a preset time period, it means that the user maintains a sitting posture on the bed body for a period of time after the original active state, and it is determined that the user has a rest tendency, and the user behavior intention is set as a lying-in-bed trend.

[0097] The embodiment of the application uses a radar module to segment and analyze the key point positions of the human body monitored by an individual, and determines the user behavior intention by using the relative position relationship between the first trunk segment and the second trunk segment connected by the crotch. The recognition accuracy of the user intention is improved, and the use experience of the user for the air conditioner and the auxiliary getting-up-and-lying-in-bed is optimized.

[0098] On the basis of any of the above embodiments, the target interval includes an increasing first included angle interval, a second included angle interval and a third included angle interval.

[0099] Specifically, the air conditioner and the interconnection control device of the auxiliary getting-up bed take the upper limit and the lower limit of the included angle between the upper body of the individual and the movable bed board under different behavior intentions as the starting point and the ending point of the threshold interval, divide the threshold interval into N-1 points, obtain N included angle subintervals, and preset a corresponding auxiliary angle change value for each included angle subinterval.

[0100] The embodiment of the present application does not specifically limit the division of the included angle subinterval.

[0101] Exemplarily, N can be 3, and the first included angle interval, the second included angle interval and the third included angle interval in which the included angle increases in turn can be [0, 5), [5, 10) and [10, +∞) respectively.

[0102] In a case where it is determined that the user behavior intention matches the getting-up trend, the movable bed board is controlled to rotate clockwise by a first bed body control instruction by an auxiliary angle change value corresponding to a target interval in which the included angle between the upper body of the individual and the movable bed board is located, to assist the individual to get up, including: if the included angle between the upper body of the individual and the movable bed board collected by the radar module is in a first included angle interval, the movable bed board is controlled to rotate clockwise by the first bed body control instruction by a first auxiliary angle change value, so that the individual leans on the bed body with the included angle between the upper body and the movable bed board being 0.

[0103] The first auxiliary angle change value is the included angle between the upper body of the individual and the movable bed board currently collected by the radar module.

[0104] Specifically, in step 103, the air conditioner and the interconnection control device of the auxiliary getting-up bed set the first auxiliary angle change value to a value corresponding to a slight included angle between the upper body of the individual and the movable bed board if it is determined that the included angle between the upper body of the individual and the movable bed board is in the first included angle interval, that is, the user individual tends to keep a certain distance between the back and the movable bed board, and that the user subjectively hopes to pull away a little distance when the movable bed board rotates clockwise to a certain position, but cannot be too far away to stop the movable bed board from continuing to rotate, so that the movable bed board compensates for the angle error between the individual and the bed body after the individual pulls away from the bed body in the tendency and is fixed at the current position, so that the individual can lean on the bed body.

[0105] If the included angle between the upper body of the individual and the movable bed board collected by the radar module is in a second included angle interval, the movable bed board is controlled to rotate clockwise by the first bed body control instruction by a second auxiliary angle change value, so that the individual gets up under the action of the movable bed board pushing the back of the upper body of the individual.

[0106] The second auxiliary angle change value is determined according to the rated rotation angle of the movable bed board when the auxiliary getting-up bed is in a bed surface lifting state.

[0107] Specifically, in step 103, if the interconnection control device of the air conditioner and the auxiliary getting-on-and-off bed determines that the included angle between the upper body of the individual and the movable bed board is in the second included angle interval, that is, the user individual tends to keep his back close to the movable bed board to obtain the support of the movable bed board, the corresponding second auxiliary angle change value is set as the difference between the rated rotation angle of the movable bed board when the auxiliary getting-on-and-off bed is fully lifted on the bed surface and the current rotation angle, so that the movable bed board is always close to the back of the individual during the clockwise rotation until the bed is lifted to the rated position to complete the auxiliary task of supporting the individual to stand upright.

[0108] If the included angle between the upper body of the individual and the movable bed board collected by the radar module is in the third included angle interval, the movable bed board is rotated counterclockwise by a third auxiliary angle change value through the first bed body control instruction, so that the individual stands up by himself without changing the position of the movable bed board.

[0109] The third auxiliary angle change value is 0.

[0110] Specifically, in step 103, if the interconnection control device of the air conditioner and the auxiliary getting-on-and-off bed determines that the included angle between the upper body of the individual and the movable bed board is in the third included angle interval, that is, the user individual has good action force and can complete getting up without the support of the movable bed board, the corresponding third auxiliary angle change value is set to 0, so that the movable bed board is fixed at the current position to perform the auxiliary task when the posture changes subsequently.

[0111] The embodiment of the present application divides the included angle interval between the upper body of the individual and the movable bed board into magnitudes, so that the auxiliary angle change value of the movable bed board in the auxiliary getting-on-and-off bed is determined as the corresponding preset magnitude value in the magnitude, which realizes quantitative adjustment of the rotation amount of the movable bed board according to the relative distance between the upper body of the individual and the movable bed board, dynamically matches the lifting of the auxiliary getting-on-and-off bed with the posture of the user individual, improves the comfort and safety of the user using the auxiliary getting-on-and-off bed, and also considers energy saving.

[0112] On the basis of any of the above embodiments, after the first bed body control instruction is used to rotate the movable bed board clockwise by the first auxiliary angle change value, or the first bed body control instruction is used to rotate the movable bed board clockwise by the second auxiliary angle change value, the method further comprises: after the individual is determined to move away from the auxiliary getting-on-and-off bed by the radar module, the movable bed board is controlled to rotate counterclockwise to reset by a second bed body control instruction.

[0113] Specifically, after step 103, the interconnection control device of the air conditioner and the auxiliary getting-out-of-bed bed controls the air conditioner and the auxiliary getting-out-of-bed bed to complete the getting-up of the user individual, and then the relative position relationship between the individual and the auxiliary getting-out-of-bed bed in the indoor space is collected by the radar module, and the relative position relationship is used as the basis for resetting control.

[0114] If the relative distance between the individual and the auxiliary getting-out-of-bed bed in the indoor space is greater than or equal to a preset threshold, it indicates that the individual is far away from the bed body after getting up and is active, and then the movable bed board is controlled to rotate counterclockwise to be flat with the fixed bed board after the first auxiliary angle change value or the second auxiliary angle change value is changed, so as to complete the resetting of the bed body.

[0115] If the relative distance between the individual and the auxiliary getting-out-of-bed bed in the indoor space is less than the preset threshold, it indicates that the individual is still around the bed body after getting up, and it is determined that the individual does not have the tendency to be active, and the resetting is temporarily not performed.

[0116] After the movable bed board is controlled to rotate clockwise to assist the user individual to get up, the relative distance between the individual and the bed body is judged, and the bed body is controlled to reset when the individual is completely away from the bed body. The bed is directly reset after the auxiliary getting-out-of-bed bed completes the auxiliary task and the user does not use the auxiliary getting-out-of-bed bed again within a period of time, so as to avoid invalid occupation of space and save energy.

[0117] On the basis of any of the above embodiments, after the user behavior intention is determined, if the user behavior intention matches the bed lying trend, the movable bed board is controlled to rotate clockwise by a target rated rotation angle by a third bed body control instruction, and the included angle between the upper body of the individual and the movable bed board is monitored by the radar module.

[0118] The target rated rotation angle is a rated rotation angle of the movable bed board when the auxiliary getting-out-of-bed bed is in a bed surface lifting state.

[0119] It should be noted that the target rated rotation angle refers to a rated rotation angle of the movable bed board relative to the fixed bed board when the auxiliary getting-out-of-bed bed is in a bed surface lifting state.

[0120] Specifically, after step 102, the interconnection control device of the air conditioner and the auxiliary getting-out-of-bed bed compares and queries the behavior intention corresponding to the posture in which the individual exhibits the human body feature.

[0121] If the user behavior intention matches the bed lying trend, the movable bed board is controlled to rotate clockwise by a target rated rotation angle by a third bed body control instruction, and the included angle between the upper body of the individual and the movable bed board is monitored by the radar module after the auxiliary getting-out-of-bed bed is in a bed surface lifting state.

[0122] If the user behavior intention does not match the bed-lying trend, no further processing is performed, and further analysis is required.

[0123] When it is determined that the included angle between the upper body of the individual and the movable bed board is decreasing, the movable bed board is controlled to rotate counterclockwise to reset by a fourth bed body control instruction.

[0124] Specifically, the interconnection control device of the air conditioner and the auxiliary bed determines that the upper body of the user gradually fits to the movable bed board according to the included angle between the upper body of the individual and the movable bed board decreasing over time, and there is a tendency to gradually lie flat by relying on the bed body to descend, and sends a fourth bed body control instruction to the auxiliary bed to make the auxiliary bed respond to the instruction to rotate the movable bed board counterclockwise from the current position until reset, and the descending process of the movable bed board provides auxiliary support force for the lying action of the individual under different intentions.

[0125] In the process of positioning the human body position by the radar module, the new execution angle of the yawing leaf assembly is first fitted according to the position of the head of the individual to swing the wind up and down above the head of the individual, and the user behavior intention is determined by the key point position of the human body monitored by the radar module. When the user behavior intention matches the bed-lying trend, the movable bed board is first controlled to rotate clockwise to completely rise, and then the angle between the upper body of the individual and the movable bed board is determined to decrease over time, and the auxiliary bed is controlled to gradually reset to assist the individual to lie flat. When the air conditioner and the auxiliary bed establish a communication relationship in the same local area network, the working states of the air conditioner and the auxiliary bed are cooperatively controlled according to the posture change of the user, the user does not need to manually adjust the parameters of the two intelligent devices respectively, the control time delay of the two intelligent devices can be reduced, the control precision can be improved, and the use experience of the user for the air conditioner and the auxiliary bed can be optimized.

[0126] On the basis of any of the above embodiments, when it is determined that the included angle between the upper body of the individual and the movable bed board is decreasing, the movable bed board is controlled to rotate counterclockwise to reset by a fourth bed body control instruction, including: if it is determined that the included angle between the upper body of the individual and the movable bed board decreases to a first threshold value, and is maintained at a state less than the first threshold value and greater than a second threshold value within a preset time length, the counterclockwise rotation of the movable bed board is stopped by the fourth bed body control instruction, so that the individual leans on the fixed movable bed board during the descending process with the upper body.

[0127] It should be noted that the first threshold value and the second threshold value respectively refer to the lower limit and the upper limit of the included angle interval between the upper body of the individual and the movable bed board when the user tends to keep his back close to the movable bed board to get the support of the movable bed board.

[0128] Specifically, after the angle between the upper body of the individual and the movable bed plate gradually decreases to the first threshold value over time, and the angle is maintained at a state of being less than the first threshold value and greater than the second threshold value within a preset time length, it is indicated that the user individual tends to keep a certain distance between the back and the movable bed plate. When the movable bed plate is counterclockwise rotated to a certain position, the user subjectively desires to shorten a little distance, but cannot be too close, so as to make it stop continuing to rotate. A fourth bed body control instruction is sent to the auxiliary getting-out-of-bed bed, so that the auxiliary getting-out-of-bed bed counterclockwise rotates the movable bed plate on the basis of the current position in response to the instruction, so that the movable bed plate compensates for the angle error between the individual and the bed body after the individual shortens the angle in the tendency, and is fixed at the current position, so as to enable the individual to lean on the bed body.

[0129] If it is determined that the angle between the upper body of the individual and the movable bed plate decreases to the first threshold value and continues to decrease to 0 within a preset time length after the angle decreases to the first threshold value, the movable bed plate is controlled to be counterclockwise rotated to reset by the fourth bed body control instruction, so that the individual lies flat along with the movable bed plate as the movable bed plate is gradually lowered.

[0130] Specifically, after the angle between the upper body of the individual and the movable bed plate gradually decreases to the first threshold value over time, and the angle is maintained at a state of being less than the first threshold value and greater than the second threshold value within a preset time length, it is indicated that the user individual tends to keep a certain distance between the back and the movable bed plate. When the movable bed plate is counterclockwise rotated to a certain position, the user subjectively desires to shorten a little distance, but cannot be too close, so as to make it stop continuing to rotate. A fourth bed body control instruction is sent to the auxiliary getting-out-of-bed bed, so that the auxiliary getting-out-of-bed bed counterclockwise rotates the movable bed plate on the basis of the current position in response to the instruction, so that the movable bed plate compensates for the angle error between the individual and the bed body after the individual shortens the angle in the tendency, and is fixed at the current position, so as to enable the individual to lean on the bed body.

[0131] Exemplarily, Figure 3 is a flowchart of the interconnection control method of the air conditioner and the auxiliary getting-out-of-bed bed provided by the present application. Figure 4 is a distribution diagram of the air conditioner and the auxiliary getting-out-of-bed bed provided by the present application. As Figure 3 and Figure 4 indicated, the present application embodiment gives a specific implementation of the interconnection control method of the air conditioner and the auxiliary getting-out-of-bed bed:

[0132] (1) After the air conditioner is started, the human body posture trajectory is captured by the millimeter wave radar, and the top edge is raised by 5° on the basis of the air conditioner inclination angle to obtain a target execution angle.

[0133] (2) Continue to capture the human body by radar into two segments, according to the first trunk segment and the second trunk segment obtained by analyzing the respective continued posture, determine the user behavior intention. If the user behavior intention shows a trend of getting up, step (3) is executed, if the user behavior intention shows a trend of lying in bed, step (4) is executed.

[0134] (3) Capture the angle α between the upper segment of the human body and the bed body by radar (as shown in Figure 4 ), and analyze it:

[0135] If the angle α is within the first threshold (5°) for 2s, it is considered that the old people need to lean on the bed, and the bed body is controlled to start the leaning mode, so that the angle α tends to 0° to real-time fit the upper segment of the human body for reliance.

[0136] If the angle α is within the first and second thresholds [5°, 10°] for 2s, it is considered that the old people need assistance to get up, and the bed body is controlled to start the getting up mode, so that the bed is raised to 70° to real-time support the upper segment of the human body for getting up.

[0137] If the angle α is greater than the second threshold (10°) for 2s, it is considered that the old people do not need assistance to get up, and the bed body is not moved.

[0138] (4) First control the bed body to rotate 70° clockwise to be raised close to the human body in sitting position.

[0139] (5) Capture the angle α between the upper segment of the human body and the bed body from 20° to 0° by radar, and control the bed body to reset.

[0140] (6) During the resetting rotation of the bed body, if the angle α is within the first and second thresholds [5°, 10°] for 2s, the bed body stops rotating and enters the leaning mode

[0141] (7) During the resetting rotation of the bed body, the angle α changes from the first threshold 10° to 0° to fit within 2s, and the bed body resets and rotates.

[0142] The embodiment of the present application realizes quantitative adjustment of the rotation amount of the movable bed plate according to the relative distance between the upper half of the individual and the movable bed plate by changing the trend of the angle between the upper half of the individual and the movable bed plate, so that the lifting and lowering of the assisted getting up and lying down bed dynamically matches the posture of the user individual, improves the comfort and safety of the user using the assisted getting up and lying down bed, and also considers energy saving.

[0143] Figure 5 is a structural schematic diagram of the interconnection control device of the air conditioner and the assisted getting up and lying down bed provided by the present application. On the basis of any of the above embodiments, as Figure 5As shown, the device is arranged in an air conditioner arranged in the same indoor environment as the auxiliary bed, the auxiliary bed is arranged with a fixed bed plate and a movable bed plate rotating relative to the fixed bed plate, and comprises a supply air control module 510, a behavior recognition module 520 and a first auxiliary joint control module 530.

[0144] The supply air control module 510 is configured to update the lower boundary of the default swing range of the horizontal guide plate assembly to the target execution angle based on the head position of each individual monitored by the radar module.

[0145] The behavior recognition module 520 is configured to determine the user behavior intention by monitoring the key point position of the human body of each individual by the radar module during the process of controlling the horizontal guide plate assembly to swing up and down in the new swing range.

[0146] The first auxiliary joint control module 530 is configured to control the movable bed plate to rotate clockwise by an auxiliary angle change value corresponding to the target range according to the first bed body control instruction in the case that the user behavior intention matches the getting-up trend, so as to assist the individual to get up.

[0147] The target execution angle is greater than the included angle between the head position of the individual and the vertical direction of the radar module. The target range is one of all included angle sub-ranges between the upper body of the elderly during the execution of the getting-up action and the movable bed plate. Any of the included angle sub-ranges is respectively provided with an auxiliary angle change value of the movable bed plate rotating relative to the fixed bed plate.

[0148] Specifically, the supply air control module 510, the behavior recognition module 520 and the first auxiliary joint control module 530 are sequentially electrically connected.

[0149] The supply air control module 510 receives the human feature information collected by the radar module in real time for each individual in the space where the air conditioner is arranged after the air conditioner is turned on, and extracts the position information corresponding to the head feature of each individual to calculate the included angle of the head position of the human body relative to the vertical line where the radar module is arranged. The target execution angle is obtained by continuously expanding the included angle upward, so that the target execution angle is greater than the azimuth angle of the head position of the human body.

[0150] Then, the target execution angle is encapsulated into the air conditioner control instruction and sent to the indoor unit, so that the horizontal swing leaf assembly formed by the vertical arrangement of the plurality of guide vanes at the air outlet of the indoor unit updates the lower boundary of the original default swing range to the target execution angle on the basis of keeping the upper boundary of the default swing range unchanged, to form a new swing range.

[0151] The behavior recognition module 520 determines that the cross guide plate assembly has been in the process of up and down free swing in the new swing area according to the running state of the yawing leaf assembly, continuously monitors the human feature information of each individual through the radar module, connects the human key point positions contained therein, and analyzes the corresponding posture, maps the individual posture to the corresponding user behavior intention, and outputs.

[0152] The first auxiliary joint control module 530 compares the behavior intention corresponding to the posture of the individual showing the human feature:

[0153] If the user behavior intention matches the getting-up trend, the radar module is used to collect the included angle between the upper body of the individual and the active bed plate, the included angle sub-interval in which the current included angle is located is taken as the target interval, and the auxiliary angle change value corresponding to the included angle sub-interval is taken as the rotation angle to be executed by the auxiliary sit-to-stand bed in the current control.

[0154] Then, the auxiliary angle change value is packaged into the first bed body control instruction and sent to the auxiliary sit-to-stand bed, so that the auxiliary sit-to-stand bed rotates the active bed plate clockwise by the corresponding auxiliary angle change value based on the current position, and provides auxiliary assistance for the individual's getting-up action under different intentions in the process of raising the active bed plate.

[0155] If the user behavior intention does not match the getting-up trend, no further processing is performed, and further analysis is required.

[0156] Optionally, the behavior recognition module 520 includes a torso segmentation unit and a behavior recognition unit, wherein:

[0157] The torso segmentation unit is configured to determine, based on the human key point positions monitored by the radar module for each individual, a first torso segment and a second torso segment connected by a hip key point for each individual.

[0158] The behavior recognition unit is configured to set the user behavior intention to a getting-up trend if an included angle formed by the first torso segment and the second torso segment at the hip key point decreases from 180° over a preset time period.

[0159] If the included angle formed by the first torso segment and the second torso segment at the hip key point continuously maintains 90° over a preset time period, the user behavior intention is set to a bed trend.

[0160] The first torso segment is determined at least according to a head key point and a hip key point, and the second torso segment is determined at least according to the hip key point and a foot key point.

[0161] Optionally, the target interval includes a first included angle interval, a second included angle interval, and a third included angle interval.

[0162] The first auxiliary joint control module 530 is specifically configured to, if the included angle between the upper body of the individual collected by the radar module and the active bed board is in a first included angle interval, rotate the first active angle change value clockwise through the first bed body control instruction, so that the individual always reclines on the bed body in a state that the included angle between the upper body and the active bed board is 0.

[0163] The first auxiliary joint control module 530 is specifically configured to, if the included angle between the upper body of the individual collected by the radar module and the active bed board is in a second included angle interval, rotate the second active angle change value clockwise through the first bed body control instruction, so that the individual gets up under the action of the active bed board assisting the back of the upper body.

[0164] The first auxiliary joint control module 530 is specifically configured to, if the included angle between the upper body of the individual collected by the radar module and the active bed board is in a third included angle interval, rotate the third active angle change value clockwise through the first bed body control instruction, so that the individual gets up by himself under the condition that the position of the active bed board does not change.

[0165] The first active angle change value is the included angle between the upper body of the individual currently collected by the radar module and the active bed board. The second active angle change value is determined according to the rated rotation angle of the active bed board when the auxiliary getting-on-and-off bed is in a bed surface lifting state. The third active angle change value is 0.

[0166] Optionally, the device comprises a reset module, wherein:

[0167] The reset module is configured to, after determining that the individual is away from the auxiliary getting-on-and-off bed through the radar module, control the active bed board to rotate counterclockwise through a second bed body control instruction.

[0168] Optionally, the device comprises an auxiliary preparation module and a second auxiliary joint control module, wherein:

[0169] The auxiliary preparation module is configured to, after determining that the user behavior intention matches the bed lying trend, control the active bed board to rotate clockwise through a third bed body control instruction to a target rated rotation angle, and then monitor the included angle between the upper body of the individual and the active bed board by using the radar module.

[0170] The second auxiliary joint control module is configured to, after determining that the included angle between the upper body of the individual and the active bed board is decreasing, control the active bed board to rotate counterclockwise through a fourth bed body control instruction to a reset position.

[0171] The target rated rotation angle is a rated rotation angle of the active bed board when the auxiliary getting-on-and-off bed is in a bed surface lifting state.

[0172] Optionally, the second auxiliary joint control module is specifically configured to, if it is determined that the included angle between the upper body of the individual and the active bed plate decreases to the first threshold value, maintain the state of being less than the first threshold value and greater than the second threshold value within a preset time length, and stop the counterclockwise rotation of the active bed plate through the fourth bed body control instruction, so that the individual leans on the active bed plate with the upper body in the fixed active bed plate during the lowering process.

[0173] The second auxiliary joint control module is specifically configured to, if it is determined that the included angle between the upper body of the individual and the active bed plate decreases to the first threshold value, continue to decrease to 0 within a preset time length, and control the active bed plate to rotate counterclockwise to reset through the fourth bed body control instruction, so that the individual lies along with the active bed plate gradually lying flat in the state that the included angle between the upper body and the active bed plate is 0.

[0174] The air conditioner and the auxiliary getting-up-and-lying-down bed interconnection control device provided by the embodiments of the present application are used to execute the air conditioner and the auxiliary getting-up-and-lying-down bed interconnection control method provided by the present application, the implementation manners of which are consistent with those of the air conditioner and the auxiliary getting-up-and-lying-down bed interconnection control method provided by the present application, and the same beneficial effects can be achieved, which will not be described herein again.

[0175] In the process of positioning the human body position through the radar module, the embodiments of the present application first fit a new execution angle of the horizontal swing leaf assembly according to the head position of the individual to swing the air up and down above the head of the individual, and also determine the user behavior intention by using the radar module to monitor the key point position of the human body of the individual. When the user behavior intention matches the getting-up trend, the angle corresponding to the target interval between the upper body of the individual and the active bed plate is determined, so that the auxiliary getting-up-and-lying-down bed adjusts the auxiliary angle change value corresponding to the interval to assist the individual to get up. When the air conditioner and the auxiliary getting-up-and-lying-down bed establish a communication relationship in the same local area network, the working states of the air conditioner and the auxiliary getting-up-and-lying-down bed are cooperatively controlled according to the posture change of the user, the user does not need to manually adjust the parameters of the two intelligent devices respectively, the control time delay of the two intelligent devices can be reduced, the control precision can be improved, and the use experience of the user for the air conditioner and the auxiliary getting-up-and-lying-down bed can be optimized.

[0176] Figure 6 is a structural schematic diagram of the air conditioner provided by the present application. On the basis of any of the above embodiments, as shown in Figure 6 The air conditioner includes an indoor unit 610 and an outdoor unit 620, the indoor unit 610 is provided with a control processor 611 and a radar module 612, the radar module 612 is arranged on the surface of the shell of the indoor unit 610; further comprising a storage and a program or instruction stored on the storage and executable on the control processor 611, the program or instruction is executed by the control processor 611 to execute the interconnection control method of the air conditioner and the display device.

[0177] The indoor unit 610 is connected to the auxiliary bed through a local area network under the same indoor space;

[0178] The auxiliary bed is used to receive and respond to the bed body control instruction issued by the indoor unit 610 when the indoor unit 610 executes the interconnection control method of the air conditioner and the auxiliary bed, and control the rotation of the movable bed plate relative to the fixed bed plate.

[0179] The radar module 612 includes a millimeter wave radar.

[0180] Specifically, the air conditioner and the auxiliary bed are in the same indoor environment, and are connected through the same local area network. The air conditioner is provided with an indoor unit 610 and an outdoor unit 620 connected through a refrigerant pipeline. The radar module 612 is embedded on the surface of the shell of the indoor unit 610. When the user activates the air conditioner, the control processor 611 uses the radar module 612 to collect the human feature information of each individual in the space where the air conditioner is located in real time, extracts the position information corresponding to the head feature of each individual, and calculates the angle between the human head position and the vertical line where the radar module is located. On the basis of the angle, the target execution angle is continued to be expanded to make the target execution angle greater than the azimuth angle of the human head.

[0181] Then, the target execution angle is packaged into the air conditioner control instruction and sent to the indoor unit 610, so that the yawing leaf assembly formed by the vertical arrangement of the plurality of guide vanes at the air outlet of the indoor unit 610 updates the lower boundary of the original default swing area to the target execution angle to form a new swing area while keeping the upper boundary of the default swing area unchanged.

[0182] The control processor 611 determines the running state of the yawing leaf assembly and determines that the horizontal guide plate assembly is in the process of freely swinging up and down in the new swing area. The radar module 612 continuously monitors the human feature information of each individual, connects and analyzes the human key point positions contained therein, maps the individual posture to the corresponding user behavior intention, and outputs it.

[0183] The control processor 611 compares the behavior intention corresponding to the posture corresponding to the human feature exhibited by the individual:

[0184] If the user behavior intention matches the getting-up trend, the radar module 612 collects the angle between the upper body of the individual and the movable bed plate, and uses the angle sub-interval where the current angle is located as the target interval, and uses the auxiliary angle change value corresponding to the angle sub-interval as the rotation angle to be executed by the auxiliary bed in this round of control.

[0185] Then, the auxiliary angle change value is packaged into a first bed body control instruction and sent to the auxiliary sit-to-stand bed, so that the auxiliary sit-to-stand bed rotates the movable bed board clockwise by the corresponding auxiliary angle change value on the basis of the current position, and provides auxiliary assistance for the individual's getting-up action in different intentions in the process of lifting the movable bed board.

[0186] If the user behavior intention does not match the getting-up trend, no further processing is performed, and further analysis is required.

[0187] In the process of positioning the human body position by the radar module, the new execution angle of the horizontal swing leaf assembly is fitted according to the head position of the individual, so as to swing the air up and down above the head of the individual, and the user behavior intention is determined by the key point position of the human body monitored by the radar module, when the user behavior intention matches the getting-up trend, the target interval corresponding to the angle between the upper body of the individual and the movable bed board is determined, so that the auxiliary sit-to-stand bed adjusts the auxiliary angle change value corresponding to the interval to assist the individual to get up. When the air conditioner and the auxiliary sit-to-stand bed establish a communication relationship in the same local area network, the working state of the air conditioner and the auxiliary sit-to-stand bed is cooperatively controlled according to the user's posture change, the user does not need to manually adjust the parameters of the two intelligent devices respectively, the control delay of the two intelligent devices can be reduced, the control precision can be improved, and the use experience of the user for the air conditioner and the auxiliary sit-to-stand bed can be optimized.

[0188] In addition, the logical instructions in the above-mentioned memory can be realized in the form of a software functional unit and sold or used as an independent product, and can be stored in a computer readable storage medium.
