Description
Technical Field
[0001] This application relates to the field of bathroom product technology, and in particular to a smart towel rack control method and system. Background Technology
[0002] Smart towel racks, also known as electric towel racks, are a new type of product that combines traditional towel racks with electric heating devices. Because bathrooms are enclosed and humid environments, towels left hanging in the bathroom for extended periods without drying can easily breed bacteria. Regular towel drying and disinfection has become a necessity, and smart, convenient electric towel racks have emerged to meet this need.
[0003] In related technologies, when a smart towel rack is in use, it determines whether there is a towel on the heating rod. When there is a towel, it obtains the corresponding humidity through a humidity sensor installed on the heating rod. When the humidity is high, it can control the heating rod to heat the towel, thereby reducing the possibility of the towel being in a damp state for a long time and thus causing bacteria to grow.
[0004] Regarding the aforementioned technologies, the inventors believe that when users use towels, they may wipe their hands or face, and in this case, the towel is not fully used; only a portion of the towel is wet. At this time, the towel near the heating rod may not be wet, and the humidity sensor on the heating rod cannot obtain the specific humidity information. Therefore, it will not control the heating rod to operate, resulting in the overall intelligent effect of the smart towel rack still being relatively poor, and there is still room for improvement. Summary of the Invention
[0005] To further improve the overall intelligence of smart towel racks, this application provides a smart towel rack control method and system.
[0006] Firstly, this application provides a smart towel rack control method, which adopts the following technical solution:
[0007] A smart towel rack control method includes:
[0008] Obtain the pressure bearing capacity of the towel at the heating rod;
[0009] Establish a unit interval on the preset time axis with the current time point as the endpoint and the preset unit time length as the width, and calculate the difference in the towel bearing pressure obtained from the front and rear endpoints of the unit interval to determine the difference bearing pressure.
[0010] When the differential bearing pressure is greater than the preset base pressure, a use signal is output, and when the use signal is output and the differential bearing pressure remains less than the base pressure for a preset fixed duration, a feasible operation signal is output.
[0011] After the feasible operation signal is output, the edge contact position of the towel and the heating rod is obtained, and the preset clamping component is controlled to move to the edge contact position to clamp and fix the towel. After the towel is clamped and fixed, the heating rod is controlled to move downward and perform heating operation with the preset heating power.
[0012] The humidity value and the contact status of the preset contact points on both sides of the heating rod are acquired when the heating rod moves downward.
[0013] Determine whether the detected humidity value is lower than the preset baseline processing value;
[0014] If the detected humidity value is less than the baseline processing value, the heating rod is controlled to move downward by a preset fixed distance to re-judge the detected humidity value until the contact state of both contact points is consistent with the preset empty state, at which point the heating rod is controlled to rise to the preset initial position.
[0015] If the detected humidity value is not less than the baseline processing value, the heating rod will be kept in its original state until the detected humidity value is less than the baseline processing value.
[0016] By adopting the above technical solution, after the user uses the towel, this situation can be determined. At this time, the heating rod can be controlled to move to heat and dry each area of the towel, so as to reduce the occurrence of the situation where the towel is used but the heating rod does not trigger the heating command, and further improve the overall intelligent effect of the smart towel rack.
[0017] Optionally, the method may also include a step of determining the heating power, which includes:
[0018] After the feasible operation signal is output, the ranging component preset at the bottom of the heating rod is controlled to rotate along the preset rotation path to obtain the line of sight offset angle and obstacle interval distance;
[0019] When the obstacle interval distance is less than the preset reasonable upper limit distance, the height deviation distance is calculated based on the line of sight offset angle and the obstacle interval distance;
[0020] The maximum height deviation distance is determined according to a preset sorting rule, and this height deviation distance is defined as the permissible movement distance.
[0021] The towel bearing pressure at the front end of the unit interval corresponding to the signal output is defined as the dry towel pressure, and the towel bearing pressure at the rear end of the unit interval corresponding to the feasible operation signal is defined as the wet towel pressure.
[0022] The pressure required to add moisture is determined by calculating the difference between the pressure of a wet towel and the pressure of a dry towel.
[0023] The water distribution width corresponding to the water addition pressure is determined based on the preset width matching relationship, and the heating preparation distance is calculated based on the water distribution width and the permissible movement distance.
[0024] The heating power corresponding to the pressure of the wet towel and the heating preparation distance is determined based on the preset power matching relationship.
[0025] By adopting the above technical solution, the theoretical maximum position of moisture is determined based on the increased moisture content, so as to determine a more suitable heating power so that the heating rod can reach the corresponding drying temperature when it encounters a humid area, thereby improving the overall heating and drying effect.
[0026] Optionally, after the water addition pressure is determined, the intelligent towel rack control method also includes:
[0027] After using the signal output, the lowering coverage state of the preset lowering point is obtained, wherein the lowering point is located between two contact points on the lower arc surface of the heating rod;
[0028] The duration for which the coverage state and the preset bonding state are consistent before the feasible operation signal is output is recorded to determine the deployment and usage time;
[0029] Timing is performed after the use signal is output and before the feasible operation signal is output to determine the overall judgment time, and the overall usage time is calculated based on the overall judgment time and the fixed time.
[0030] The percentage of usage before and after the decentralization is determined by calculating the usage time before and after the decentralization and the overall usage time.
[0031] The pressure compensation value corresponding to the usage ratio before and after is determined based on the preset compensation matching relationship, and the pressure for adding water is adjusted and updated based on the pressure compensation value.
[0032] By adopting the above technical solution, the specific usage of the front and back sides of the towel can be determined based on the coverage of the distribution point, thereby determining a more accurate water addition pressure to determine the water distribution width.
[0033] Optionally, the smart towel rack control method further includes the following when the heating rod moves downward:
[0034] Get the downward movement distance in real time;
[0035] When the detected humidity value is not less than the baseline processing value, the downward movement distance is defined as the starting working distance;
[0036] The deviation handling distance is determined by calculating the difference between the starting operation distance and the heating preparation distance.
[0037] The required processing power is determined based on the preset demand matching relationship, which corresponds to the deviation processing distance and the moisture addition pressure. The heating rod is then controlled to operate at the required processing power.
[0038] By adopting the above technical solution and adjusting the operating power of the heating rod according to the actual situation, the overall heating effect of the towel can be better.
[0039] Optionally, after the clamping component clamps the towel, the smart towel rack control method further includes:
[0040] The distance between the edges is determined based on the contact points of the two edges;
[0041] Determine if the distance between the edges is less than the preset towel width;
[0042] If the distance between the edges is not less than the width of the towel, then control the heating rod to move downwards;
[0043] If the distance between the edges is less than the width of the towel, then control the two clamping components to move in opposite directions along the length of the heating rod and obtain a restricted pulling force;
[0044] When the restricted tension exceeds the preset damage tension, the clamping component is controlled to stop moving, and the component spacing distance between the two clamping components is obtained after both clamping components have stopped moving;
[0045] The overlap ratio of the towels is determined by calculation based on the distance between the components and the width of the towels;
[0046] The adjustment power corresponding to the towel overlap ratio is determined according to the preset adjustment matching relationship, and the heating power is corrected according to the adjustment power. After the heating power is corrected, the heating rod is controlled to move downward.
[0047] By adopting the above technical solution, it is possible to determine whether the towel is folded. When folded, the unfoldable towel is unfolded to facilitate heating and drying.
[0048] Optionally, the step of controlling the two clamping assemblies to move in opposite directions along the length of the heating rod includes:
[0049] Obtain the movable distance between the corresponding endpoints of the clamping component and the heating rod;
[0050] Determine if the movable distance is less than the preset reasonable distance;
[0051] If the movable distance is not less than a reasonable distance, then control the clamping component to move normally in the opposite direction;
[0052] If the movable distance is less than a reasonable distance, then the clamping component is defined as a limited component, and the other clamping component is defined as an open component, and the adjustment direction is determined based on the limited component and the open component;
[0053] Control the two clamping components to move synchronously along the adjustment direction until the movable distance of both clamping components is greater than the preset unit distance. Then continue to control the clamping components to move in opposite directions.
[0054] By adopting the above technical solutions, the occurrence of towels failing to unfold effectively can be reduced.
[0055] Optionally, after the towel overlap ratio is determined, the intelligent towel rack control method further includes:
[0056] Determine if the overlap ratio of the towels is greater than the preset flat lay ratio;
[0057] If the overlap of the towels is not greater than the flat area, then the clamping components are kept in their original state and the heating rod is moved downwards.
[0058] If the overlap ratio of the towels is greater than the flat ratio, then obtain the clamping thickness value of the clamping component;
[0059] The clamping component with the larger clamping thickness value is defined as the deployable component, and the other clamping component is defined as the fixed component.
[0060] The offset direction is determined based on the deployable component and the fixed component, and the two clamping components are controlled to move synchronously along the offset direction until the movable distance of the fixed component is a reasonable distance, at which point the movement stops to control the heating rod to move downward.
[0061] By adopting the above technical solution, the side of the towel that has been unfolded can be placed near the end of the heating rod, making it convenient for the user to manually unfold the other side of the towel later.
[0062] Secondly, this application provides an intelligent towel rack control system, which adopts the following technical solution:
[0063] A smart towel rack control system includes:
[0064] The acquisition module is used to acquire the pressure borne by the towel at the heating rod.
[0065] The processing module, connected to the acquisition and judgment modules, is used for information storage and processing;
[0066] The judgment module, connected to the acquisition and processing modules, is used for judging information.
[0067] The processing module establishes a unit interval on the preset time axis with the current time point as the endpoint and the width as the preset unit time length, and calculates the difference in the towel bearing pressure obtained from the front and rear endpoints of the unit interval to determine the difference bearing pressure.
[0068] The processing module outputs a usage signal when the differential bearing pressure is greater than the preset base pressure, and outputs a feasible operation signal when the usage signal is output and the differential bearing pressure remains less than the base pressure for a preset fixed duration.
[0069] After the feasible operation signal is output, the acquisition module acquires the edge contact position between the towel and the heating rod, and causes the processing module to control the preset clamping component to move to the edge contact position to clamp and fix the towel. After the towel is clamped and fixed, the heating rod is controlled to move downward and perform heating operation with the preset heating power.
[0070] The module acquires the detected humidity value and the contact status of the preset contact points on both sides of the heating rod as the heating rod moves downward;
[0071] The judgment module determines whether the detected humidity value is less than a preset benchmark value;
[0072] If the judgment module determines that the detected humidity value is less than the baseline processing value, the processing module controls the heating rod to move downward by a preset fixed distance to re-judge the detected humidity value until the contact state of the two contact points is consistent with the preset empty state, and then controls the heating rod to rise to the preset initial position.
[0073] If the judgment module determines that the detected humidity value is not less than the baseline processing value, the processing module controls the heating rod to maintain its original state until the detected humidity value is less than the baseline processing value.
[0074] By adopting the above technical solution, after the user uses the towel, this situation can be determined. At this time, the heating rod can be controlled to move to heat and dry each area of the towel, so as to reduce the occurrence of the situation where the towel is used but the heating rod does not trigger the heating command, and further improve the overall intelligent effect of the smart towel rack.
[0075] In summary, this application includes at least one of the following beneficial technical effects:
[0076] 1. It can accurately determine the user's towel usage, enabling the towel rack to operate when the towel is in use, thus improving the overall intelligence of the smart towel rack;
[0077] 2. During the operation of the heating rod, different power levels can be adjusted according to the overall dampness of the towel to achieve the best overall heating effect.
[0078] 3. Before heating and drying the towels, unfold any folded towels to facilitate the subsequent drying process. Attached Figure Description

[0088] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-9 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.
[0089] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.
[0090] This application discloses an intelligent towel rack control method, which determines whether a towel is being used based on changes in the pressure value on the heating rod. When a towel is being used, the overall condition of the towel can be analyzed, and the towel can be effectively dried and heated by combining the clamping component and the heating rod, thereby improving the overall intelligent effect of the intelligent towel rack.
[0091] Reference Figure 1 The method flow for controlling an intelligent towel rack includes the following steps:
[0092] Step S100: Obtain the pressure of the towel at the heating rod.
[0093] The towel bearing pressure is the pressure value received on the heating rod on the towel rack, which is obtained by a pressure sensor installed on the upper surface of the heating rod; the overall width of the heating rod is sufficient to place a single towel, but not two towels.
[0094] Step S101: Establish a unit interval on the preset time axis with the current time point as the end point and the width as the preset unit time length, and calculate the difference in the towel bearing pressure obtained from the front and rear ends of the unit interval to determine the difference bearing pressure.
[0095] The time axis is a coordinate axis formed by combining various time points. The unit duration is a fixed duration set by the staff, usually 1 second. Establishing a unit interval makes it easier to judge the changes in data within the unit duration. The differential bearing pressure is the change in pressure on the heating rod within the unit duration, which is determined by subtracting the towel bearing pressure at the front end of the unit interval from the towel bearing pressure at the rear end of the unit interval.
[0096] Step S102: When the differential bearing pressure is greater than the preset base pressure, output a usage signal, and when the usage signal is output and the differential bearing pressure remains less than the base pressure for a preset fixed duration, output a feasible operation signal.
[0097] The base pressure is the minimum pressure that the user applies to the heating rod when dragging the towel, as set by the operator. When the differential bearing pressure is greater than the base pressure, it indicates that the user is using the towel placed on the heating rod, and a usage signal is output to mark and record this situation. The fixed duration is the minimum duration set by the operator when the pressure on the heating rod remains unchanged for an extended period. When the usage signal is output and the differential bearing pressure remains fixed for a duration less than the base pressure, it indicates that the user has finished using the towel, and the towel can be heated and dried. A feasible operation signal is output to mark and record this situation.
[0098] Step S103: After the feasible operation signal is output, obtain the edge contact position of the towel and the heating rod, and control the preset clamping component to move to the edge contact position to clamp and fix the towel. After the towel is clamped and fixed, control the heating rod to move downward and perform heating operation with the preset heating power.
[0099] The edge contact position is the endpoint of the contact point between the towel and the heating rod along the length direction. This can be determined by setting a light sensor on the heating rod. When the towel covers the light sensor, it indicates that the towel is present at the corresponding position. In this case, only the light sensors at the two ends covered by the towel need to be identified. The clamping component is a movable clamping component installed on the towel rack, similar to a mechanical gripper. The clamping component can clamp the end of the towel that is in contact with the heating rod to separate the towel from the surface of the heating rod. When the heating rod moves downward, the position of the towel is fixed and will not move downward synchronously with the heating rod. This allows the heating rod to heat the damp area below the towel, so that the damp area can be directly heated without the need for indirect heating through the already dry part of the towel. This not only improves the overall heating effect but also reduces heat consumption. The heating power is the power of the heating rod when it is heating. This power can be a set value set by the operator or determined according to the specific dampness of the towel. The specific method can be selected by the operator according to the actual situation. The specific determination method in this embodiment will be described below and will not be repeated here.
[0100] Step S104: When the heating rod moves downward, obtain the detected humidity value and the contact status of the preset contact points on both sides of the heating rod.
[0101] The contact points are the points on both sides of the heating rod that come into contact with the towel. These contact points are spaced apart along the length of the heating rod, as shown in the reference diagram. Figure 2 The contact state, i.e. whether the contact point is in direct contact with the towel, can be determined by setting a distance sensor at the contact point; the detected humidity value is the humidity value obtained by the humidity sensor installed on the heating rod. Similarly, the humidity sensor is set at intervals along the length of the heating rod, and the determined detected humidity value is the maximum humidity value detected by all humidity sensors.
[0102] Step S105: Determine whether the detected humidity value is less than the preset baseline processing value.
[0103] The baseline processing value is the minimum humidity value detected when the towel is considered to be damp, as set by the staff. The purpose of this judgment is to determine whether a damp area on the towel has been detected, so as to determine whether the heating rod needs to be left to dry.
[0104] Step S1051: If the detected humidity value is less than the baseline processing value, control the heating rod to move downward by a preset fixed distance to re-judge the detected humidity value until the contact state of the two contact points is consistent with the preset empty state, then control the heating rod to rise to the preset initial position.
[0105] When the detected humidity value is lower than the baseline processing value, it means that the towel position currently in contact with the heating rod does not require heating and drying. At this time, the heating rod is controlled to move a fixed distance to detect different positions of the towel. The fixed distance is the range that the heating rod can cover in a single heating operation. The "released state" is the contact state set by the operator when the towel is not in contact. When the contact states of both contact points are consistent with the "released state", it means that the drying process of all areas of the towel has been completed. At this time, the heating rod is controlled to rise to the initial position. The initial position is the position where the heating rod does not move down and can support the towel. After the heating rod moves to the initial position, the clamping component can cancel the clamping function and return to the set position to wait for the next operation.
[0106] Step S1052: If the detected humidity value is not less than the baseline processing value, control the heating rod to maintain its original state until the detected humidity value is less than the baseline processing value.
[0107] When the detected humidity value is not less than the baseline processing value, it indicates that the towel currently in contact with the heating rod needs to be heated and dried. At this time, the heating rod is controlled to maintain its original state to achieve the heating and drying process of the towel.
[0108] Reference Figure 3 It also includes a step for determining the heating power, which includes:
[0109] Step S200: After the feasible operation signal is output, control the distance measuring component preset at the bottom of the heating rod to rotate along the preset rotation path to obtain the line of sight offset angle and obstacle interval distance.
[0110] The ranging component is a distance sensor mounted at the bottom of the heating rod's cross-section and capable of rotating along the cross-section. The detection probe of the ranging component faces away from the center of the heating rod's cross-section. Figure 2 Similarly, the ranging components are spaced apart along the length of the heating rod; the rotation path is such that the detection range of the ranging component is 120°; the line of sight offset angle is the angle formed by the detection direction of the ranging component and the vertical direction; and the obstacle interval distance is the distance value detected by the ranging component.
[0111] Step S201: When the obstacle interval distance is less than the preset reasonable upper limit distance, calculate the height deviation distance based on the line of sight offset angle and the obstacle interval distance.
[0112] The reasonable upper limit distance is the maximum obstacle interval distance set by the staff when the obstacle detected by the ranging component is a towel. When the obstacle interval distance is less than the reasonable upper limit distance, it means that the currently detected obstacle is a towel. The height deviation distance is the distance between the detected obstacle towel area and the bottom of the heating rod in the height direction, which can be obtained by calculating the obstacle interval distance and the line of sight offset angle using trigonometric functions.
[0113] Step S202: Determine the distance with the largest height deviation according to the preset sorting rules, and define the height deviation distance as the permissible movement distance.
[0114] The sorting rules are methods set by staff to sort numerical values, such as the bubble sort method. By using the sorting rules, the distance of the largest height deviation can be determined, that is, the obstacle detected at this time is the bottom of the towel. At this time, the permissible movement distance is defined to distinguish between different height deviation distances, which is convenient for subsequent analysis.
[0115] Step S203: Define the towel bearing pressure at the front end of the unit interval corresponding to the signal output as the dry towel pressure, and define the towel bearing pressure at the rear end of the unit interval corresponding to the feasible operation signal as the wet towel pressure.
[0116] The pressure of a dry towel and the pressure of a wet towel are defined to obtain the weight of the towel at different time points, which will facilitate subsequent analysis.
[0117] Step S204: Calculate the difference between the pressure of the wet towel and the pressure of the dry towel to determine the water addition pressure.
[0118] The moisture addition pressure is the weight value of the water absorbed by the towel after the user uses it, determined by subtracting the pressure of the dry towel from the pressure of the wet towel.
[0119] Step S205: Determine the moisture distribution width corresponding to the moisture addition pressure according to the preset width matching relationship, and calculate and determine the heating preparation distance according to the moisture distribution width and the permissible movement distance.
[0120] The moisture distribution width is the range of moisture distribution in the vertical direction when water pressure is applied during normal use of the towel. The greater the water pressure, the wider the corresponding moisture distribution width. Since towels may be used on one or both sides, the width matching relationship is established based on single-sided use to cover double-sided use. The width matching relationship between the two is determined by staff through multiple tests in advance. The heating preparation distance is the theoretical distance value when the heating rod moves to the first position requiring drying, determined with the bottom of the towel as the endpoint. It is determined by subtracting the moisture distribution width from the permissible movement distance.
[0121] Step S206: Determine the heating power corresponding to the pressure of the wet towel and the heating preparation distance according to the preset power matching relationship.
[0122] Different pressures on the damp towels indicate different required heating and drying temperatures. Similarly, different heating preparation distances result in different preparation times for the heating rod, thus requiring different heating powers. The power matching relationship between these three factors is pre-determined by the staff and will not be elaborated further.
[0123] Reference Figure 4 After the water addition pressure is determined, the intelligent towel rack control method also includes:
[0124] Step S300: After using the signal output, obtain the preset lowering point coverage state, wherein the lowering point is located between two contact points on the lower arc surface of the heating rod.
[0125] The lowering point is the location between two contact points on the cross-section of the heating rod. This lowering point is closer to the contact point located at the rear; that is, during the installation of the towel rack, the lowering point is relatively close to the contact point on the side facing the wall. (Refer to...) Figure 2 The placement point and the contact point are set one-to-one, and the sensor set at the placement point is the same as that at the contact point. The placement coverage state is the state of whether the placement point is in contact with the towel.
[0126] Step S301: Record the duration for which the coverage state and the preset bonding state are consistent before the feasible operation signal is output to determine the duration of deployment.
[0127] The "fitting state" refers to the state of the towel when it is in contact with the lowering point. If the lowering coverage state is consistent with the "fitting state" before the "feasible operation signal" is output, it means that the user has dragged and used the towel behind, indicating that the user is currently using a double-sided towel. The lowering usage time is the duration for which the user uses the towel behind.
[0128] Step S302: Timing is performed after the use signal is output and before the feasible operation signal is output to determine the overall judgment duration, and the overall usage duration is calculated based on the overall judgment duration and the fixed duration.
[0129] The overall judgment duration is the time period between the output of the use signal and the output of the feasible operation signal. The overall usage duration is the time the user uses the towel, which is determined by subtracting the fixed duration from the overall judgment duration.
[0130] Step S303: Calculate the usage ratio before and after based on the usage time of the decentralized service and the overall usage time.
[0131] The ratio of pre- and post-use time is the ratio of the time a user spends using the towel before and after using it, and is determined by the ratio of the time spent using the towel before and after using it to the overall usage time.
[0132] Step S304: Determine the pressure compensation value corresponding to the usage ratio before and after based on the preset compensation matching relationship, and adjust and update the moisture addition pressure according to the pressure compensation value.
[0133] The pressure compensation value is a correction value for the water addition pressure. Different usage ratios before and after indicate that the water absorption of the towel is different before and after. Since the determined width matching relationship is based on the situation when using a single towel, it is necessary to adjust the water addition pressure according to the usage ratio before and after, so that the determined water distribution width is more accurate. The method for updating the water addition pressure is to subtract the pressure compensation value from the original water addition pressure, and the compensation matching relationship between the two is determined by the staff in advance based on multiple tests.
[0134] Reference Figure 5 The intelligent towel rack control method also includes the following when the heating rod moves downward:
[0135] Step S400: Obtain the downward movement distance in real time.
[0136] The downward movement distance is the total movement distance of the heating rod when it moves downward, which can be determined by installing a displacement sensor on the moving slide rail of the heating rod.
[0137] Step S401: When the detected humidity value is not less than the baseline processing value, the downward movement distance is defined as the starting working distance.
[0138] When the detected humidity value is not less than the baseline processing value, it means that the heating rod has detected a damp area on the towel for the first time. At this time, the starting working distance is defined to distinguish different downward movement distances, which is convenient for subsequent analysis.
[0139] Step S402: Calculate the difference between the starting working distance and the heating preparation distance to determine the deviation handling distance.
[0140] The deviation handling distance is the theoretical distance between the top wet point of the towel and the actual top wet point of the towel, which is determined by subtracting the heating preparation distance from the starting operation distance.
[0141] Step S403: Determine the required processing power corresponding to the deviation processing distance and the moisture addition pressure according to the preset demand matching relationship, and control the heating rod to operate at the required processing power.
[0142] Different deviation processing distances indicate different drying requirements under the same moisture addition pressure. There may be areas with higher humidity. The required processing power is the heating rod power value that can effectively heat the damp areas on the towel. The matching relationship between the three requirements is determined by the staff in advance through multiple tests.
[0143] Reference Figure 6 After the clamping component clamps the towel, the intelligent towel rack control method also includes:
[0144] Step S500: Determine the distance between the edges based on the contact positions of the two edges.
[0145] The edge spacing is the distance between the two determined edge contact positions.
[0146] Step S501: Determine whether the distance between the edges is less than the preset towel width.
[0147] The towel width is the overall width of the towel entered by the user when using the towel rack. It can also be determined by the number of contact points covered when the towel is placed upright. The purpose of this determination is to know whether the towel is currently folded.
[0148] Step S5011: If the distance between the edges is not less than the width of the towel, then control the heating rod to move downwards.
[0149] When the distance between the edges is not less than the width of the towel, it indicates that the possibility of the towel being folded is low, and the heating rod can be operated normally at this time.
[0150] Step S5012: If the distance between the edges is less than the width of the towel, control the two clamping components to move in opposite directions along the length of the heating rod and obtain a restricted pulling force.
[0151] When the distance between the edges is less than the width of the towel, it indicates that the towel is folded. If the heating rod is used directly to heat the towel, it will consume more energy to dry the towel, and further analysis and processing are required. The restricted tension is the tension value from another clamping component during the movement of the clamping component, which can be determined by setting a tension sensor on the clamping component.
[0152] Step S502: When the restricted tension is greater than the preset damage tension, control the clamping component to stop moving, and after both clamping components stop moving, obtain the component spacing distance between the two clamping components.
[0153] The damage tension is the minimum tension set by the staff when the towel cannot be fully unfolded. When the restricted tension is greater than the damage tension, it means that the clamping components cannot continue to unfold the towel. When both clamping components stop moving, it means that the towel has been fully unfolded. At this time, there may still be cases where the towel is not fully unfolded, which requires further analysis. The component spacing is the distance between the two clamping components, which is also the width of the towel currently hanging on the heating rod.
[0154] Step S503: Calculate the towel overlap ratio based on the component spacing and towel width.
[0155] The towel overlap ratio is the percentage of the towel that is folded after the clamping component moves. It is determined by subtracting the distance between the components from the towel width and then dividing by the towel width. When the towel overlap ratio is less than zero, it indicates that the towel is placed at an angle.
[0156] Step S504: Determine the adjustment power corresponding to the towel overlap ratio according to the preset adjustment matching relationship, and correct the heating power according to the adjustment power, and control the heating rod to move downward after the heating power is corrected.
[0157] When the overlap ratio of towels is different, it indicates that the size of the overlapping area is different, and the power required for the operation is also different. Adjusting the power means adjusting the heating power value. By combining the adjusted power with the heating power, the heating power can be corrected. The matching relationship between the two is determined in advance by the staff. By correcting the heating power, the towel drying effect is better. Similarly, the required processing power can be corrected by adjusting the power to further improve the towel drying effect.
[0158] Reference Figure 7 The steps of controlling the two clamping assemblies to move in opposite directions along the length of the heating rod include:
[0159] Step S600: Obtain the movable distance between the clamping component and the corresponding endpoint of the heating rod.
[0160] The corresponding end point of the heating rod is the end point of the heating rod closest to the clamping component, and the movable distance is the distance between the clamping component and this end point.
[0161] Step S601: Determine whether the movable distance is less than the preset reasonable distance.
[0162] The reasonable distance is the minimum distance set by the staff that allows the clamping component to move towards the end point. The purpose of the judgment is to determine whether there is a suitable space between the clamping component and the end point of the heating rod for the clamping component to move.
[0163] Step S6011: If the movable distance is not less than a reasonable distance, control the clamping component to move normally in the opposite direction.
[0164] When the movable distance is not less than a reasonable distance, it means that there is suitable space for the clamping component to move. At this time, the movement of the clamping component can be controlled normally.
[0165] Step S6012: If the movable distance is less than the reasonable distance, the clamping component is defined as a limiting component, and the other clamping component is defined as an open component. The adjustment direction is determined based on the limiting component and the open component.
[0166] When the movable distance is less than the reasonable distance, it means that there is no suitable space for the clamping component to move. In this case, further analysis is needed. Defining limited components and open components can distinguish different clamping components, which is convenient for subsequent control processing. Adjust the direction so that the limited component points to the direction of the open component.
[0167] Step S602: Control the two clamping components to move synchronously along the adjustment direction until the movable distance of both clamping components is greater than the preset unit distance of the reasonable distance, then continue to control the clamping components to move in opposite directions.
[0168] Controlling the two clamping components to move synchronously along the adjustment direction can increase the movable space of the limited components. When the movable distance is greater than the reasonable unit distance, it means that there is a suitable space for the clamping components to move. At this time, normal control of the clamping components to move is sufficient. The unit distance is the fixed distance set by the operator.
[0169] Reference Figure 8 After determining the towel overlap ratio, the intelligent towel rack control method also includes:
[0170] Step S700: Determine whether the overlap ratio of the towels is greater than the preset flat ratio.
[0171] The flatness ratio is the percentage of overlap of the towel when it is fully unfolded, as defined by the staff. Under normal circumstances, this flatness ratio is 0. The purpose of this determination is to determine whether the towel has been fully unfolded.
[0172] Step S7001: If the overlap ratio of the towels is not greater than the flat ratio, control the clamping component to maintain its original state and control the heating rod to move downward.
[0173] When the overlap of the towels is no greater than the flat area, it means that the towels are fully unfolded and you can proceed with the work normally.
[0174] Step S7002: If the overlap ratio of the towels is greater than the flat ratio, then obtain the clamping thickness value of the clamping component.
[0175] When the overlap ratio of the towel is greater than the flat ratio, it indicates that there are still some parts of the towel that are not unfolded, that is, there are situations where the clamping components are holding the towel at the folded position, which requires further analysis; the clamping thickness value is the thickness of the towel held by the clamping components when they clamp the towel, which can be obtained by checking the closure of the clamping components.
[0176] Step S701: Define the clamping component with the larger clamping thickness value among the two clamping components as an expandable component, and define the other clamping component as a fixed component.
[0177] A larger clamping thickness value indicates that the corresponding clamping component is clamping the folded position of the towel. At this point, define the expandable component and the fixing component for subsequent analysis and control.
[0178] Step S702: Determine the offset direction based on the deployable component and the fixed component, and control the two clamping components to move synchronously along the offset direction until the movable distance of the fixed component is a reasonable distance, then stop moving to control the heating rod to move downward.
[0179] The offset direction is towards the fixed component from the expandable component. The two clamping components are controlled to move synchronously along the offset direction and stop moving when the movable distance of the fixed component is a reasonable distance. After the heating rod completes its work and rises to the initial position, there is still a large space on the heating rod for the unexpanded end of the towel to be unfolded. This allows the user to manually unfold the towel without having to move the towel, making it convenient for the user to use the towel.
[0180] Reference Figure 9 Based on the same inventive concept, embodiments of the present invention provide an intelligent towel rack control system, comprising:
[0181] The acquisition module is used to acquire the pressure borne by the towel at the heating rod.
[0182] The processing module, connected to the acquisition and judgment modules, is used for information storage and processing;
[0183] The judgment module, connected to the acquisition and processing modules, is used for judging information.
[0184] The processing module establishes a unit interval on the preset time axis with the current time point as the endpoint and the width as the preset unit time length, and calculates the difference in the towel bearing pressure obtained from the front and rear endpoints of the unit interval to determine the difference bearing pressure.
[0185] The processing module outputs a usage signal when the differential bearing pressure is greater than the preset base pressure, and outputs a feasible operation signal when the usage signal is output and the differential bearing pressure remains less than the base pressure for a preset fixed duration.
[0186] After the feasible operation signal is output, the acquisition module acquires the edge contact position between the towel and the heating rod, and causes the processing module to control the preset clamping component to move to the edge contact position to clamp and fix the towel. After the towel is clamped and fixed, the heating rod is controlled to move downward and perform heating operation with the preset heating power.
[0187] The module acquires the detected humidity value and the contact status of the preset contact points on both sides of the heating rod as the heating rod moves downward;
[0188] The judgment module determines whether the detected humidity value is less than a preset benchmark value;
[0189] If the judgment module determines that the detected humidity value is less than the baseline processing value, the processing module controls the heating rod to move downward by a preset fixed distance to re-judge the detected humidity value until the contact state of the two contact points is consistent with the preset empty state, and then controls the heating rod to rise to the preset initial position.
[0190] If the judgment module determines that the detected humidity value is not less than the benchmark processing value, the processing module controls the heating rod to maintain its original state until the detected humidity value is less than the benchmark processing value.
[0191] The heating power determination module determines a reasonable heating power based on the amount of moisture added to the towel.
[0192] The moisture addition pressure correction module adjusts the moisture addition pressure based on the specific usage conditions of both sides of the towel.
[0193] The processing power determination module determines the appropriate processing power based on the actual humidity levels at various points on the towel.
[0194] The overlapping unfolding control module unfolds the unfoldable towels when they are overlapping.
[0195] The clamping movement control module is used to control the movement of the clamping components;
[0196] The towel position adjustment module is used to adjust the overall position of the towels, making it easier for users to unfold towels that cannot be unfolded later.

In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above. The specific working process of the system, device, and unit described above can be referred to the corresponding process in the foregoing method embodiments, and will not be repeated here.
