[0048] Figure 1 is one of the flowcharts of the millimeter wave radar-based air conditioner old-age assistance control method provided by the present application. As shown in Figure 1 the millimeter wave radar-based air conditioner old-age assistance control method provided by the embodiment of the present application, wherein the air conditioner and the wheelchair are arranged in the same indoor environment, comprises: step 101, in the case that the posture information of at least one individual is determined to be a preset joint control wake-up posture, and the duration of the joint control wake-up posture reaches a preset threshold, the air conditioner is controlled to start a sleep mode, and the wheelchair is controlled to start a joint control mode.
[0049] Among them, the posture information is determined according to the human feature information collected by the radar module for each individual in the default working mode of the air conditioner.
[0050] It should be noted that the execution subject of the millimeter wave radar-based air conditioner old-age assistance control method provided by the embodiment of the present application is the millimeter wave radar-based air conditioner old-age assistance control device.
[0051] The application scenario of the millimeter wave radar-based air conditioner old-age assistance control method provided by the embodiment of the present application is that the air conditioner and the wheelchair 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, the wheelchair far away is controlled to move to the vicinity of the individual, and the air supply mode of the air conditioner is adjusted accordingly.
[0052] Among them, the radar module is arranged on the air conditioner, periodically collects all individuals in the indoor environment for monitoring in a specified time interval, and sends the distribution position of the human body of each individual in the space to the millimeter wave radar-based air conditioner old-age assistance control device. The working period of the radar module is not limited in the embodiment of the present application.
[0053] Optionally, the radar module can perform collection work in the default working period.
[0054] Optionally, the user can change the working period of the radar module by issuing a period change instruction, so that the radar module receives and responds to the instruction to change the working period to the period indicated by the instruction for collection work.
[0055] 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.
[0056] Optionally, the user can transmit the activation instruction by controlling the device through the wireless communication mode between the control device and the air conditioning system, so as to initialize the working mode of the air conditioning system and start the radar module.
[0057] Optionally, the user can issue an 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.
[0058] Specifically, in step 101, after the air conditioner starts the default working mode, the millimeter wave radar air conditioner old people control device receives the human feature information collected by the radar module for each individual in the space where the air conditioner is located, analyzes the human shape features contained therein, and if the posture information analyzed by any individual matches the pre-set joint control wake-up posture, and the individual maintains the joint control wake-up posture for a duration reaching a pre-set threshold, it means that the individual's current behavior intention is to actively perform the joint control wake-up action to activate the joint control of the air conditioner and the wheelchair, so that the wheelchair in the distance moves to the individual's vicinity.
[0059] The joint control of the air conditioner and the wheelchair includes adjusting the fan speed of the indoor unit and the operating frequency of the outdoor unit to the parameter values corresponding to the sleep mode based on the current operating mode of the air conditioner. At the same time, it also includes activating the wheelchair and starting the motor of the wheelchair in the joint control mode, and ensuring that the wheelchair has no fault and waits to travel according to the planned path through the forward and backward micro-motions of the wheels generated by the initialization of the drive wheels.
[0060] Conversely, if the posture information of any individual does not match the pre-set joint control wake-up posture, or the individual maintains the joint control wake-up posture for a duration that does not reach the pre-set threshold, it means that the individual's current behavior intention is only to make some specific actions in the indoor space, and there is no need to use the wheelchair, so the joint control of the air conditioner and the wheelchair is not triggered.
[0061] Wherein, the type and number of radar sensing devices in the radar module are not specifically limited in the embodiment of the application.
[0062] For example, the radar module can include a laser radar, an infrared sensor, etc.
[0063] Optionally, since 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, is not affected by light, and has a faster response speed.
[0064] Therefore, based on the millimeter wave radar air conditioner old people control device, the posture of the user individual in the current behavior action is analyzed according to the individual contour information collected by the millimeter wave radar in real time.
[0065] Exemplarily, the radar module can include multiple types of sensing elements such as millimeter wave radar, laser radar, infrared sensor, etc., and the millimeter wave radar air conditioner assisted old control device integrates the contour information collected by each sensing element to comprehensively depict the real-time posture of the individual.
[0066] It can be understood that the preset joint control wake-up posture is not specifically limited in the embodiment of the application.
[0067] Exemplarily, the joint control wake-up posture can be pre-set according to the individual's own action conditions, and after determining the body part with normal action ability, the action posture that can be performed by the body part is selected as the joint control wake-up posture.
[0068] For example, the lower limbs of the individual are paralyzed, but the arms can withstand the amplitude of most basic actions, so the individual's waving hand action at a certain frequency can be used as the joint control wake-up posture.
[0069] For another example, the individual has hemiplegia caused by stroke, but the hand can still maintain a certain action, so the individual's fingers maintaining a certain specific posture can be used as the joint control wake-up posture.
[0070] Step 102, based on the first posture information monitored by the radar module on the target individual, and the second posture information monitored by the radar module on the wheelchair, the wheelchair is controlled to travel to the fixed position where the target individual is located, and then assist the target individual to sit down.
[0071] Among them, the target individual is any one of the individuals in the indoor space in the joint control wake-up posture.
[0072] It should be noted that the target individual refers to an individual who continuously maintains the joint control wake-up posture in the current space, and the individual has a demand for calling a wheelchair from a distance, so the individual's subjective action intention is to activate the joint control of the air conditioner and the wheelchair.
[0073] Specifically, in step 102, based on the millimeter wave radar air conditioner assisted old control device, after determining that the sleep mode of the air conditioner and the joint control mode of the wheelchair are both turned on, the radar module in the joint control mode is used to monitor the first posture information of the target individual in the indoor space and the second posture information of the wheelchair in the indoor space, and the action route of the wheelchair is planned and corrected in real time according to the relative position relationship between the two, until the wheelchair travels to the fixed position where the target individual is located, directly meets the demand of the target individual for calling the wheelchair, and provides the function of assisting the seat.
[0074] The indoor space coordinate system is established with the position of the radar module as the origin, the horizontal line where the air conditioner is located is taken as the X-axis, the vertical line perpendicular to the X-axis in the horizontal plane where the air conditioner is located is taken as the Y-axis, the XoY plane is formed to represent the horizontal plane where the air conditioner is located, and the direction perpendicular to the XoY plane and downward is defined as the positive direction of the Z-axis.
[0075] The first pose information refers to the position coordinates of the target individual in the indoor space coordinate system and the corresponding azimuth angle. Due to the conditions of the target individual, generally, the first pose information does not change much.
[0076] The second pose information refers to the position coordinates of the wheelchair in the indoor space coordinate system and the corresponding azimuth angle. The second pose information changes over time to adjust the route, angle and distance of the wheelchair to the target individual in real time according to the changes in the relative position relationship between the user and the wheelchair.
[0077] Step 103: After determining that the target individual is seated, the swing range of the air conditioner is adjusted according to the position information of the target individual changed under the action of the wheelchair.
[0078] It should be noted that before step 103, the wheelchair needs to monitor whether the function of assisting the target individual to sit down is completed after the wheelchair approaches the target individual, and the embodiments of the present application do not make specific limitations on this.
[0079] For example, a pressure sensor can be installed below the seat of the wheelchair. When the pressure sensor monitors that the seat bears the pressure generated by the individual sitting on the seat, and the pressure value reaches the body weight of the individual, the wheelchair sends a signal to the air conditioner to indicate that the target individual has sat down.
[0080] For example, the radar module on the air conditioner can continue to monitor the posture of the individual. When the radar module monitors that the human posture is sitting, it is determined that the target individual has sat down.
[0081] Specifically, in step 103, after the millimeter wave radar air conditioner old-age control device determines that the target individual has completed sitting down at the current position, the target individual can change the position in the indoor space under the action of the wheelchair. The swing range of the air conditioner is adjusted according to the real-time position information of the target individual when the radar module continues to drive, so as to realize the function of "wind following the movement of the person".
[0082] The adjustment strategy of the swing range includes that the execution angle of the yawing leaf assembly arranged in parallel along the vertical direction at the air outlet of the air conditioner is always aligned with the real-time position of the target individual when the target individual changes the position under the action of the wheelchair, so that the yawing leaf assembly changes the wind guide direction in the vertical direction with the change of the body distribution range of the target individual in the vertical direction.
[0083] The adjustment strategy of the swing range further includes always aligning the execution angle of the vertical swing vane assembly parallelly arranged along the horizontal direction at the air outlet of the air conditioner with the real-time position of the target individual when the wheelchair is actuated to displace, so as to change the air guiding direction of the vertical swing vane assembly in the horizontal direction with the displacement of the target individual in the horizontal direction.
[0084] When the posture information of at least one individual monitored by the radar module shows a tendency to continuously maintain the wake-up posture, the linkage control between the air conditioner and the wheelchair is activated, and the relative position relationship between the target individual and the wheelchair activating the mode is captured by the radar module in real time to guide the wheelchair to the target individual to assist in seating, and then when the radar module monitors that the wheelchair carrying the target individual displaces in the indoor space, the swing range of the air conditioner is always aligned with the target individual. When the air conditioner and the wheelchair establish a communication relationship in the same local area network, the working states of the air conditioner and the wheelchair are cooperatively controlled according to the posture change of the user, without the user manually adjusting the two intelligent devices respectively, so that the wheelchair far away can automatically move to the user's position to provide assistance, reduce the control delay of the two intelligent devices, improve the control accuracy, and optimize the user's experience of using the air conditioner and the wheelchair.
[0085] On the basis of any of the above embodiments, based on the first posture information monitored by the radar module on the target individual and the second posture information monitored by the radar module on the wheelchair, the wheelchair is controlled to travel to the fixed position of the target individual to assist the target individual in seating, including: based on the first posture information and the second posture information, the wheelchair is controlled to travel to the target individual corresponding to the assist receiving range and brake.
[0086] Among them, the assist receiving range is a acceptable action range determined with the fixed position of the target individual as the center.
[0087] Specifically, in step 102, based on the millimeter wave radar air conditioner old control device, according to the second posture information of the empty wheelchair when it travels along the predetermined route, the angle and distance changes relative to the first posture information change over time, gradually guide the wheelchair to travel to the target individual corresponding to the assist receiving range, and then control the wheelchair to brake and temporarily stop in the assist receiving range to wait for further control instructions to approach the target individual.
[0088] Among them, the assist receiving range is a symmetric region divided with the fixed position of the target individual as the center.
[0089] Exemplarily, the assist receiving range can be a symmetric region divided with the fixed position of the target individual as the center and combined with the fixed distance from the target individual.
[0090] Exemplarily, the auxiliary receiving range can also be an action range divided with the fixed position where the target individual is currently located as the center, and matching the action ability of the target individual itself. The worse the action ability of the individual is, the smaller the radius of the auxiliary receiving range is.
[0091] For example, the auxiliary receiving range can be limited to a circumferential range of 0.5 meters (m) from the target individual.
[0092] In the case that the orientations of the target individual and the wheelchair are determined to be the same by the radar module, the wheelchair is controlled to travel to the auxiliary execution position in the auxiliary receiving range to assist the target individual to sit down.
[0093] The auxiliary execution position is closest to the fixed position where the target individual is located in the auxiliary receiving range.
[0094] Specifically, the orientation of the target individual is determined based on the azimuth angle in the first pose information collected by the radar module when the wheelchair is stationary in the auxiliary receiving range, and the orientation of the wheelchair opening is also determined according to the azimuth angle in the second pose information collected by the radar module at this time. The orientations of the two are compared:
[0095] If the orientations of the two are consistent, it means that the wheelchair seat is open to the target individual, and the target individual does not need other actions in addition to the sitting action. Therefore, the wheelchair is directly controlled to continue traveling in the auxiliary receiving range along its current orientation until it is braked at the auxiliary execution position to wait for the target individual to sit down.
[0096] The auxiliary execution position refers to the last path point in the predetermined route of the target individual when the wheelchair moves, and the planning of the path point needs to meet the requirement that after the movement direction of the last path point is continued, it is closest to the rear side of the target individual.
[0097] If the orientations of the two are consistent, it means that the wheelchair seat is not directly opposite to the back of the target individual, and the target individual needs to adjust its orientation to sit down. Therefore, the wheelchair is first controlled to be consistent with the orientation of the target individual, and then the wheelchair is controlled to continue traveling in the auxiliary receiving range towards the target individual until it is braked at the auxiliary execution position to wait for the target individual to sit down.
[0098] The embodiment of the present application guides the empty wheelchair to move to the auxiliary receiving range to wait for the judgment of the orientation based on the change of the relative position relationship of the first pose information relative to the second pose information, and decides to control the wheelchair to continue to assist in executing the position along the current orientation when the target individual and the wheelchair orientation are consistent. The wheelchair can execute more accurate assisted seating function in the process of controlling the empty wheelchair to approach the individual, and the control precision is improved, the physical consumption of the person in executing unnecessary actions is effectively avoided, and the use experience of the air conditioner and the wheelchair is optimized.
[0099] On the basis of any of the above embodiments, based on the first pose information and the second pose information, the wheelchair is controlled to travel to the auxiliary receiving range corresponding to the target individual to brake, comprising: determining an initial planning path based on the first pose information and the second pose information.
[0100] Specifically, based on the millimeter wave radar air conditioner old-age assistance control device, an initial planning path is obtained from the initial collected first pose information and second pose information, combined with the existing path planning algorithm, taking the initial position of the wheelchair as the starting point and the position of the target individual as the end point.
[0101] In a case where at least one path point in the initial planning path is in the object coordinate set, an obstacle avoidance planning path is determined based on the target object coordinate set and the initial planning path, so that the wheelchair continues to travel along the obstacle avoidance planning path to the auxiliary receiving range.
[0102] Wherein, the target object coordinate set is any object coordinate set in the object coordinate set which intersects with the path point coordinate of the initial planning path, and the object coordinate set is obtained by scanning the distribution range of any object in the indoor space by the radar module.
[0103] It should be noted that before step 102, the object distribution in the indoor space needs to be scanned by the radar module to obtain a set of object coordinate sets covered by each object in the indoor space coordinate system.
[0104] Specifically, based on the millimeter wave radar air conditioner old-age assistance control device, the path points recorded by the initial planning path are compared with all object coordinate sets:
[0105] If it is confirmed through comparison that there is an intersection between the two, that is, the initial planning path has a path point coinciding with the position of the indoor object, the object coordinate set with route conflict is taken as the target object coordinate set, and after setting it as an obstacle avoidance point, the initial planning path is re-planned in combination to obtain an obstacle avoidance planning path, and the obstacle avoidance planning path is sent to the wheelchair. So that the wheelchair avoids all obstacles along the obstacle avoidance planning path from the initial position to the position of the target individual.
[0106] The embodiment of the present application obtains an initial planning path based on first pose information and second pose information, and performs cross comparison on the initial planning path and the distributed positions of indoor objects. When it is detected that there is an obstacle on the route of the initial planning path, the obstacle avoidance planning path is re-planned by combining the target object coordinate set corresponding to the obstacle and the initial planning path. On the basis of automatic obstacle avoidance of the wheelchair, the wheelchair can approach the individual with the shortest route and the fastest time, improve the control accuracy of the wheelchair, reduce the waiting time of the user for the wheelchair as much as possible, and optimize the use experience of the user for the air conditioner and the wheelchair.
[0107] On the basis of any of the above embodiments, after the initial planning path is determined, the wheelchair is controlled to travel along the initial planning path to the auxiliary receiving range in a case where all path points in the initial planning path are not located in any object coordinate set.
[0108] Specifically, the initial planning path recorded by the millimeter wave radar air conditioner old-age control device is compared with all object coordinate sets:
[0109] If it is confirmed through comparison that there is no intersection between the two, that is, the initial planning path has no path point coinciding with the position of any indoor object, the initial planning path is directly sent to the wheelchair. So that the wheelchair moves from the initial position to the position of the target individual along the initial planning path.
[0110] The embodiment of the present application obtains an initial planning path based on first pose information and second pose information, and performs cross comparison on the initial planning path and the distributed positions of indoor objects. When it is detected that there is an obstacle on the route of the initial planning path, the obstacle avoidance planning path is re-planned by combining the target object coordinate set corresponding to the obstacle and the initial planning path. On the basis of automatic obstacle avoidance of the wheelchair, the wheelchair can approach the individual with the shortest route and the fastest time, improve the control accuracy of the wheelchair, reduce the waiting time of the user for the wheelchair as much as possible, and optimize the use experience of the user for the air conditioner and the wheelchair.
[0111] On the basis of any of the above embodiments, the wheelchair is controlled to assist the target individual to sit down after traveling to the assistance execution position in the assistance receiving range, comprising: if the assistance execution position and the fixed position where the target individual is located are on the same horizontal line, according to the target orientation of the target individual relative to the wheelchair, the target armrest of the wheelchair is controlled to rotate and expand to be parallel to the wheelchair back to assist the target individual to sit down.
[0112] Wherein, the target armrest is one of the two armrests of the wheelchair on the side of the target orientation.
[0113] Specifically, the assistance execution position where the empty wheelchair completes the predetermined route and the fixed position where the target individual is located are compared based on the millimeter wave radar air conditioning old-age assistance control device:
[0114] If the X-axis coordinate value of the assistance execution position is approximately equal to the X-axis coordinate value of the fixed position where the target individual is located, that is, they are on the same horizontal line, the side orientation (i.e. left or right) of the target individual relative to the wheelchair is taken as the target orientation, and the armrest of the two armrests of the wheelchair on the same side as the target individual is taken as the target armrest. To assist the target individual to sit down using the target armrest, the target armrest needs to be controlled to rotate at its hinge to face the target orientation, and the target armrest needs to be fully expanded from the original perpendicular state to the chair back to the parallel state to the chair back to provide the support required by the target individual when the target individual horizontally displaces to the side.
[0115] After determining that the target individual has sat down, the target armrest is controlled to rotate at its hinge to face away from the target orientation and return to the perpendicular state to the chair back.
[0116] Specifically, after determining that the target individual has sat down, the target armrest is controlled to rotate at its hinge to face away from the target orientation and return to the perpendicular state to the chair back based on the millimeter wave radar air conditioning old-age assistance control device. To make it easy for the individual to hold the armrest when the individual's arms naturally droop after the armrest is returned, the target armrest is fully retracted from the current parallel state to the chair back to the original perpendicular state to the chair back.
[0117] The embodiment of the present application judges the relative position relationship between the assistance execution position and the fixed position where the target individual is located. When it is determined that the assistance execution position is on the horizontal side of the fixed position where the target individual is located, the target armrest on the same side as the target individual is controlled to rotate outwardly to be parallel to the wheelchair back, and is returned to be perpendicular to the back after the target individual sits down. The support force of the armrest is always present for the user during the horizontal movement to the wheelchair, perfectly connecting the user to sit down, avoiding accidents, and improving safety.
[0118] On the basis of any of the above embodiments, the wheelchair is controlled to assist the target individual to sit down after traveling to the assistance execution position in the assistance receiving range, comprising: if the assistance execution position and the fixed position where the target individual is located are on the same vertical line, the two armrests of the wheelchair are controlled to stretch forward to assist the support when the target individual sits down to the rear.
[0119] Specifically, the assistance execution position where the empty wheelchair completes the predetermined route and the fixed position where the target individual is located are compared based on the millimeter wave radar air conditioning old-age assistance control device:
[0120] If the Y-axis coordinate value of the fixed position where the target individual is located is slightly greater than the Y-axis coordinate value of the assistance execution position, that is, they are on the same vertical line, the target individual is stretched forward relative to the wheelchair to provide the support required when the target individual vertically displaced to the rear.
[0121] After determining that the target individual sits down, the two armrests are controlled to retract backward to the original state.
[0122] Specifically, after determining that the target individual completes the sitting, the two armrests are controlled to completely retract backward to the original state based on the millimeter wave radar air conditioning old-age assistance control device, so that the individual's arms carried on the wheelchair can easily hold the armrest when the armrest is retracted and the arms naturally droop, facilitating the force.
[0123] Exemplarily, Figure 2 is a flowchart of the method for assisting the old based on the millimeter wave radar air conditioning provided by the present application. As shown in Figure 2 , the present application provides a specific embodiment of the method for assisting the old based on the millimeter wave radar air conditioning:
[0124] (1) After the air conditioner is started, the human body posture trajectory is captured by the millimeter wave radar.
[0125] (2) If the human body presents a "joint control wake-up" posture, the air conditioner is controlled to enter a sleep state, and the target individual is fixedly blown.
[0126] (3) When the "joint control wake-up" posture is monitored for 20s, the joint control mode of the wheelchair is activated. Otherwise, jump to step (1) to continue monitoring the human body posture.
[0127] (4) The wheelchair is controlled to initialize the front and rear micro-movement, and the initial planning route, angle and distance of the wheelchair to the target individual are calculated according to the position of the wheelchair.
[0128] (5) The initial planning route is rechecked in combination with the distribution of space articles. If there is no obstacle on the route, step (5) is executed. Otherwise, jump to step (5) to recalculate the obstacle avoidance planning path.
[0129] (6) According to the planned path, the wheelchair is guided to run to 0.5m away from the target individual (i.e. the auxiliary receiving range), and the face direction of the target individual is captured by the radar.
[0130] (7) The wheelchair is adjusted to be consistent with the direction of the target individual, and is driven to the auxiliary execution position close to the left (right) side of the target individual, and the target handrail on the corresponding side is controlled to be unfolded outward to be parallel to the chair back.
[0131] (8) After the target individual sits on the wheelchair, the target handrail is controlled to be reset.
[0132] (9) The air conditioner is turned on in the "wind follows the person" mode.
[0133] The embodiment of the present application judges the relative position relationship between the auxiliary execution position and the fixed position where the target individual is located. When it is determined that the auxiliary execution position is directly behind the fixed position where the target individual is located, the decision control is made to extend a pair of handrails forward, and reset them to the initial state after the target individual sits down. The support force of the handrails is always present for the user to move backward to the wheelchair, perfectly connecting the user to the seat, avoiding accidents, and improving safety.

[0136] The wheelchair control module 320 is used to control the wheelchair to proceed to the fixed position of the target individual and assist the target individual to sit down based on the first posture information monitored by the radar module on the target individual and the second posture information monitored by the radar module on the wheelchair.
[0137] The air conditioner control module 330 is used to adjust the air deflection range of the air conditioner according to the changed position information of the target individual on the wheelchair after the target individual sits down.
[0138] Wherein, the target individual is any one of the individuals in a joint control wake-up posture in an indoor space. The posture information is determined according to the human feature information collected by the radar module on each individual in the default working mode of the air conditioner.
