Description

Technical Field

[0001] This application relates to the field of clothes drying control technology, specifically to methods, systems, and storage media for controlling the operation of clothes drying machines. Background Technology

[0002] Smart clothes drying racks are gaining popularity due to their ability to automatically raise and lower, and the integration of functions such as lighting, drying, and sterilization. They have become an indispensable part of smart home products.

[0003] To precisely control the position of the clothes drying rack's rod and ensure its safe and reliable operation, limit switches, including upper and lower limit switches, are typically installed at the end of the main unit. When the clothes drying rod reaches the preset maximum safe position, the limit switch is triggered, cutting off the motor power and stopping the machine from rising. Without an upper limit switch, the motor might continue running even when the rod reaches its highest position, attempting to pull the already-reached rod upwards. This could lead to severe motor overload and burnout, or damage to the steel cable, the rod hitting the top, damage to the pulleys, or even deformation and damage to the entire machine structure. Limit switches are essentially the first line of defense against mechanical damage.

[0004] Currently, limit switches for clothes drying racks are generally installed on the main unit's casing, and most of these features need to be exposed on the main unit. Specifically, the limit switch and trigger arm need to be exposed on the side wall of the main unit. This requires openings in the casing, which compromises the integrity of the casing, especially the concealed design required for recessed clothes drying racks. Furthermore, current clothes drying racks generally rely solely on the on / off state of the limit switch to determine whether the drying rod has reached its limit, which cannot guarantee reliability. Summary of the Invention

[0005] The primary objective of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a method for controlling the operation of a clothes drying rack. This method can improve the reliability of the limit switch triggering of the clothes drying rack while ensuring the integrity of the main unit housing of the clothes drying rack.

[0006] The second objective of this invention is to provide a clothes drying rack operation control system.

[0007] A third objective of this invention is to provide a computer-readable storage medium.

[0008] The fourth objective of this invention is to provide a computer program product.

[0009] The first objective of this invention is achieved through the following technical solution: a clothes drying rack operation control method, comprising:

[0010] Receive the control command for the clothes drying rack rod;

[0011] Obtain the real-time position information of the drying rack;

[0012] The trigger signal is received from the trigger element, which is installed on the main body of the clothes drying rack and is triggered when the clothes drying rack steering pulley assembly is displaced to the corresponding position;

[0013] The stopping position is determined based on the real-time position information of the drying rod and the trigger signal emitted by the triggering device;

[0014] According to the control command for the drying rack, the drying rack is controlled to stop when it reaches the designated stopping position.

[0015] Preferably, the stopping position includes a first preset position and an upper limit position;

[0016] The upper limit position is the highest position where the drying rod stops;

[0017] The first preset position is below the upper limit position, and the two are separated by a first distance.

[0018] Furthermore, when the received control command for the drying rod is a command to raise the drying rod, the stopping position is determined based on the real-time position information of the drying rod and the trigger signal emitted by the trigger element. According to the control command, the drying rod is controlled to stop when it reaches the stopping position, including:

[0019] The current position of the drying rod is determined based on the real-time position information of the drying rod; when it is determined that the current position of the drying rod is in the first position, it is determined whether a trigger signal is received from the triggering element;

[0020] If so, then determine the stopping position of the drying rack as the first preset position, control the drying rack to rise to the first preset position and then stop running;

[0021] If not, control the drying rack to continue rising;

[0022] The first position is located below the first preset position.

[0023] Furthermore, when the control command for the drying rack is a command to raise the drying rack, the stopping position is determined based on the real-time position information of the drying rack and the trigger signal. According to the control command, the drying rack is controlled to stop when it reaches the stopping position. This also includes:

[0024] When the real-time position information of the drying rod is obtained and it is determined that the current position of the drying rod is in the second position, it is determined whether a trigger signal is received from the triggering device.

[0025] If so, then determine the drying rack's stopping position as the first preset position, control the drying rack to descend back to the first preset position, and then stop the operation;

[0026] Wherein, the second position is located between the first preset position and the second preset position, the second preset position is below the upper limit position, and the two are separated by a second distance; the second distance is less than the first distance;

[0027] If not, control the drying rack to continue rising.

[0028] Furthermore, when the control command for the drying rack is a command to raise the drying rack, the stopping position of the drying rack is determined based on the real-time position information of the drying rack and the trigger signal. According to the control command, the drying rack is controlled to stop when it reaches the stopping position. This also includes:

[0029] When the real-time position information of the drying rod is obtained and it is determined that the current position of the drying rod is in the third position, it is determined whether a trigger signal is received from the triggering device.

[0030] If so, determine that the drying rack is at its upper limit position and control the drying rack to stop running;

[0031] The third position is located between the second preset position and the upper limit position.

[0032] Furthermore, when the real-time position information of the drying rod indicates that the current position of the drying rod is in the third position, the output current information of the clothes drying machine's power system is obtained. If no trigger signal is received from the triggering element and the output current of the power system exceeds the preset current threshold, the drying rod is controlled to stop running.

[0033] Furthermore, after the drying rack reaches the third position and stops running, the current position of the drying rack is refreshed to the upper limit position.

[0034] The second objective of this invention is achieved through the following technical solution: a clothes drying rack operation control system, comprising a control unit, a position detection unit, and a trigger;

[0035] The position detection unit is connected to the control unit and is used to detect the real-time position information of the drying rack and feed back the detected real-time position information of the drying rack to the control unit.

[0036] The trigger is installed on the main body of the clothes drying rack and is triggered when the clothes drying rack steering pulley assembly is displaced to the corresponding position;

[0037] The trigger is connected to the control unit and is used to send a trigger signal to the control unit when triggered;

[0038] The control unit is connected to the power system of the clothes dryer and is used to execute the clothes dryer operation control method described in the first objective of this invention.

[0039] The third objective of the present invention is achieved by the following technical solution: a computer-readable storage medium having a computer program stored thereon, characterized in that, when the computer program is executed by a processor, it implements the clothes drying machine operation control method described in the first objective of the present invention.

[0040] The fourth objective of this invention is achieved through the following technical solution: a computer program product, comprising a computer program, which, when executed by a processor, implements the clothes drying rack operation control method described in the first objective of this invention.

[0041] The present invention has the following advantages and effects compared with the prior art:

[0042] (1) The clothes drying rack operation control method of the present invention, after receiving the clothes drying rack operation control command, determines the real-time position of the clothes drying rack and obtains the trigger signal sent by the triggering element. Based on the current position information of the clothes drying rack and the triggering signal of the triggering element, the stopping position of the clothes drying rack is determined. In this invention, the triggering element is set on the main body of the clothes drying rack and can be triggered when the pulley assembly moves to the corresponding position, that is, when the pulley assembly deforms due to weight load. Based on this, the method of the present invention combines the real-time position information of the clothes drying rack and the triggering signal of the triggering element to limit the stopping position of the clothes drying rack. It considers the position of the clothes drying rack and the changes in the clothes drying rack due to load, which effectively improves the reliability of the clothes drying rack limit triggering. The dual-factor collaborative judgment method can effectively avoid accidents such as the clothes drying rack hitting the top due to the failure of a single signal. In addition, in the method of the present invention, the triggering element can be set in the main body and can be triggered by the clothes drying rack steering pulley assembly. Therefore, it does not need to be exposed outside the main body of the clothes drying rack, ensuring the integrity of the main body of the clothes drying rack.

[0043] (2) In the clothes drying rack operation control method of the present invention, the drying rod stays at a first preset position and an upper limit position; wherein the first preset position can be the drying rack position of the clothes drying rack; based on this, the method of the present invention can combine the real-time position of the drying rod and the signal triggered by the state of the drying rod to control the drying rod to stay at the drying rack position or the upper limit position, and the control is more flexible.

[0044] (3) In the clothes drying rack operation control method of the present invention, when the drying rod is currently below the first preset position (such as below the drying gear position), it is determined whether the trigger is triggered. If it is triggered, it means that the load on the drying rod exceeds a certain value and there are clothes drying on the drying rod. Therefore, the drying rod is directly controlled to only rise to the first preset position, which improves the operating efficiency of the drying rod to a certain extent. After the drying rod passes the first preset position, that is, the drying gear position, the trigger can further determine whether there are clothes hangers or other objects that may be higher than the upper surface of the drying rod. If so, after the drying rod reaches the corresponding position, the pulley assembly will be subjected to a large load and deform due to the obstruction of the clothes hangers. Based on this, the method of the present invention controls the drying rod to fall back to the drying gear position, overcoming the situation in the prior art where the light weight of the clothes cannot cause a change in the state of the drying rod and thus cannot determine whether there are clothes drying. Furthermore, when other accidents occur and cause obstruction, the drying rod falling back can further ensure the safety of the drying rod operation.

[0045] (4) In the clothes drying rack operation control method of the present invention, after the drying rod reaches the third position which is close to the upper limit position, the drying rod is recognized as having reached the upper limit position when a trigger signal is received from the triggering element, and the drying rod is controlled to stop running. It can be seen that the method of the present invention can achieve precise control of multiple positions such as the drying rack position and the upper limit position of the drying rod at the same time through a single triggering element. It overcomes the need for openings in the housing and also makes the hardware structure simpler to implement.

[0046] (5) In the clothes drying rack operation control method of the present invention, after the drying rod reaches the third position which is close to the upper limit position, the output current information of the power system (such as motor current information) is also acquired simultaneously; when no trigger signal is received from the triggering element, the drying rod is controlled to stop running when the output current information of the power system exceeds the preset current threshold; therefore, the method of the present invention provides a higher level of protection for the safe operation of the drying rod through the output current of the power system, and can avoid the situation where the drying rod hits the top due to the inability to determine that the drying rod has reached the upper limit position caused by the failure of the triggering element.

[0047] (6) In the clothes drying rack operation control method of the present invention, after the drying rod reaches the third position and the drying rod is controlled to stop running, that is, after it is determined that the drying rod has reached the upper limit position, the current position of the drying rod is refreshed to the upper limit position, so as to avoid the error caused by position detection from being accumulated in the next control, and further improves the accuracy of the clothes drying rack operation control.

[0052] The embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions of the embodiments of this application.

[0053] Example 1

[0054] Currently, limit switches on clothes drying racks are generally installed on the main unit's casing, and most of these features need to be exposed on the main unit. Specifically, the limit switch and trigger arm need to be exposed on the side wall of the main unit. This requires openings in the casing, which compromises the integrity of the casing, especially the concealed design required for recessed clothes drying racks. Furthermore, current clothes drying racks generally rely solely on the on / off state of the limit switch to determine whether the drying rod has reached its limit, meaning they depend on a single signal, which cannot guarantee reliability.

[0055] Based on the problems existing in the prior art, this embodiment provides a clothes drying rack operation control method, which can be implemented by the clothes drying rack main control module.

[0056] The clothes drying rack referred to in this embodiment generally includes a main unit and drying rods. The main unit is generally installed on the ceiling. The aforementioned drying rods generally refer to drying rod assemblies, which are set below the main unit by steel wire ropes or other lifting components. The drying rod assembly generally includes one or more clothes drying rods for drying clothes, one or more quilt drying rods for drying bedding, and one or more horizontal rods for drying small items (underwear, socks, towels, etc.). Clothes of general size are usually hung on the clothes drying rods, quilt drying rods, or small drying rods using clothing hangers (such as clothes hangers). The main unit contains a main control module, a power system, and other components. The power system of the clothes drying rack can include a motor, a reel, a pulley assembly, and cables (such as steel wire rope). The main control module is connected to the motor via a motor driver to control the motor's rotation. The reel is driven by the motor's output shaft. One end of the steel wire rope is mounted on the reel, and the other end passes through a pulley in the pulley assembly to change direction (from horizontal to vertical) and is fixedly connected to the drying rod assembly below the main unit. The reel rotates under the motor's drive, which winds up and unwinds the steel wire rope, thereby causing the drying rod assembly on the steel wire rope to rise or fall. Additionally, the clothes drying rack may be equipped with lighting, drying, and disinfection modules, which can be controlled by commands issued from the main control module on the main unit.

[0057] In the clothes drying rack used in this embodiment, such as Figure 2 As shown, the pulley assembly includes a pulley component and an elastic component; wherein the pulley component is used to guide the steel wire rope (or other type of cable component) that connects to the clothes drying rack on the clothes drying rack, the pulley component is slidably mounted on the main body of the clothes drying rack, at least one pulley component can be set at each end of the main body of the clothes drying rack, and for each pulley component, two sliding grooves can be set at the corresponding position of the main body, and the two ends of the axle passing through the pulley on the pulley component are respectively set on the two sliding grooves. One end of the elastic element is connected to the main unit, and the other end is connected to the pulley assembly, specifically to the axle on the pulley assembly. For each pulley assembly, two elastic elements can be configured, one end of each elastic element and the other end of each elastic element are connected to the two ends of the pulley assembly's axle, respectively, and the other ends of both elastic elements are fixedly connected to the main unit. The elastic element can be a tension spring. When the force on the pulley assembly does not exceed a preset threshold, the tension spring is in a reset state, and the pulley assembly is at position a (such as the highest position) under the tension of the tension spring. When the force on the pulley assembly is greater than or equal to the preset threshold, that is, when the load on the drying rod exceeds a certain value, the pulley assembly will be displaced, thereby driving the tension spring to stretch in the direction of its displacement. If the load on the drying rod disappears or decreases so that the force on the pulley assembly does not exceed the preset threshold, the pulley assembly will return to position a under the tension of the tension spring.

[0058] like Figure 1 As shown in the figure, the steps of the clothes drying rack operation control method in this embodiment include:

[0059] S1. Receive the control command for the clothes drying rack rod.

[0060] In this embodiment, the drying rack control commands include a drying rack raising control command, a drying rack lowering control command, and a drying rack stopping control command.

[0061] S2. Obtain the real-time position information of the drying rod and the trigger signal emitted by the triggering component;

[0062] In this embodiment, a Hall sensor can be used to detect the real-time position of the clothes drying rod. Specifically, the power system of the clothes drying rack includes a motor that drives the winding reel. The rotation of the motor's output shaft drives the winding reel to rotate, thereby controlling the raising and lowering of the steel wire rope. In this embodiment, a Hall sensor is placed on the motor's output shaft. The number of pulses output by the Hall sensor can detect the motor's rotation. Based on this, the position of the drying rod can be determined after appropriate calculations. This is a relatively mature technology in the prior art, and will not be elaborated upon in this embodiment. Of course, other devices can also be used to detect the position of the drying rod, such as ultrasonic sensors, infrared distance sensors, and laser sensors. These types of sensors can achieve real-time detection of the drying rod's position by being placed at the corresponding positions on the clothes drying rack.

[0063] In this embodiment, the trigger is installed on the main body of the clothes drying rack and can be triggered when the clothes drying rack's steering pulley assembly moves to the corresponding position. Furthermore, the trigger can be directly positioned on the displacement path of the clothes drying rack's steering pulley assembly, specifically in the middle of the pulley assembly's displacement path or on both sides of the path, so that it can be contacted and triggered when the pulley assembly moves to the corresponding position due to force. In this embodiment, when the pulley assembly is subjected to a force greater than or equal to a threshold, it will generate displacement. When the pulley assembly moves to a position that can trigger the trigger, the trigger will be activated, thus issuing a trigger signal. The control unit connected to the trigger (e.g., the clothes drying rack's main control module) will receive the trigger signal.

[0064] In this embodiment, the trigger can be a contact sensor or a non-contact sensor or other detection switch. When using a contact sensor, it can be a microswitch; when using a non-contact sensor, it can be a photoelectric sensor, such as an infrared sensor, laser sensor, or ultrasonic sensor. The threshold value can be 10 kg. The force on the pulley includes the weight of the clothesline itself and the weight of the clothes or other items hanging on it. When the clothesline is unloaded, i.e., no other items are hanging on it, the force on the pulley will not exceed the threshold before the clothesline reaches its upper limit, therefore the trigger will not be activated. When clothes or other items are hung on the clothesline, causing the force on the pulley assembly to be greater than or equal to the threshold, the trigger will be activated. When the clothesline reaches its upper limit or encounters an obstacle above it during its ascent, the clothesline will be obstructed, and the force on the pulley assembly will be greater than or equal to the threshold, at which point the trigger will be activated.

[0065] S3. Determine the stopping position based on the real-time position information of the drying rod and the trigger signal emitted by the trigger.

[0066] In this embodiment, the aforementioned stopping position includes a first preset position and an upper limit position; wherein: the upper limit position is the highest position where the drying rod stops, the first preset position is below the upper limit position, and the two are separated by a first distance. In this embodiment, the first preset position can be the drying setting position of the clothes drying machine, and the first distance can be 8-15cm, specifically 10cm.

[0067] S4. According to the control command of the drying rack, control the drying rack to stop when it reaches the stop position.

[0068] In this embodiment, when the received control command for the drying rod is a command to raise the drying rod, the stopping position is determined based on the real-time position information of the drying rod and the trigger signal emitted by the trigger, including:

[0069] The current position of the drying rod is determined based on the real-time position information of the drying rod; when it is determined that the current position of the drying rod is in the first position, it is determined whether a trigger signal is received from the triggering element;

[0070] If so, then determine the stopping position of the drying rack as the first preset position, control the drying rack to rise to the first preset position and then stop running;

[0071] If not, the control rod continues to rise; during the rising process, the control rod can periodically, according to a preset time or when a preset condition is met, re-determine whether a trigger signal from the triggering element has been received; until the control rod reaches the first preset position.

[0072] In this embodiment, the first position is located below the first preset position. When the clothes drying rack is rising and in the first position, the trigger signal sent by the triggering element can be periodically checked at a preset cycle, or it can be checked only a preset number of times (one or more times). If the latter, the time for each check can be preset in advance. Alternatively, a check can be performed when preset conditions are met. This embodiment does not limit this; the specific settings can be based on actual usage requirements. The aforementioned preset conditions can be when the clothes drying rack receives a preset signal sent by an external terminal, or other situations.

[0073] In this embodiment, when it is determined that the current position of the drying rod is in the second position based on the obtained real-time position information of the drying rod, it is determined whether a trigger signal issued by the triggering element has been received;

[0074] If so, then determine the drying rack's stopping position as the first preset position, control the drying rack to descend back to the first preset position, and then stop the operation;

[0075] If not, the drying rack continues to rise. During the rising process, the drying rack can periodically, according to a preset time or when a preset condition is met, re-determine whether a trigger signal from the triggering element has been received; until the drying rack reaches the second preset position.

[0076] The second position is located between the first preset position and the second preset position. This can include situations where, when the first preset position is reached, the second preset position is below the upper limit position, and the two are separated by a second distance; the second distance is less than the first distance. In this embodiment, the second distance can be 1-2 cm, specifically 1 cm, meaning the second preset position is 1 cm below the upper limit position. In this embodiment, when the drying rack is rising and in the second position, the trigger signal sent by the trigger element can be periodically judged at a preset cycle, or only judged a preset number of times (one or more times). If the latter, the time for each judgment can be preset in advance. Additionally, a judgment can be performed when preset conditions are met. The specific method is not limited in this embodiment and can be set according to actual usage requirements.

[0077] Based on the above content of this embodiment, when the drying rod is currently below the first preset position (such as below the drying level position), it is determined whether the trigger is activated. If activated, it indicates that the load on the drying rod exceeds a certain value, and there are clothes drying on the drying rod. Therefore, the drying rod is directly controlled to only rise to the drying level position, which improves the operating efficiency of the drying rod to a certain extent. After the drying rod passes the first preset position, i.e., the drying level position, the trigger can further determine whether there are clothes hangers or other objects that may be higher than the upper surface of the drying rod. If so, after the drying rod reaches the corresponding position, the clothes hangers on the drying rod may touch the main unit or the ceiling, which will hinder the continued operation of the drying rod. At this time, the pulley assembly will be subjected to a large load and deform. Based on this, the above method of this embodiment controls the drying rod to descend back to the drying level position, overcoming the situation in the prior art where the light weight of the clothes drying cannot cause a change in the state of the drying rod, and thus the inability to determine whether there are clothes drying.

[0078] In this embodiment, when the current position of the drying rod is determined to be in the third position based on the real-time position information of the drying rod, the output current information of the clothes drying machine power system is obtained, such as the motor current information in the power system, and it is determined whether a trigger signal is received from the triggering device.

[0079] If so, if the position of the drying rack is determined to be the upper limit position, control the drying rack to stop running, and at the same time refresh the current position of the drying rack to the upper limit position;

[0080] If not, obtain the output current of the clothes drying rack's power system and determine whether the output current of the clothes drying rack's power system exceeds the preset current threshold. If so, control the drying rod to stop running and refresh the current position of the drying rod to the upper limit position.

[0081] In this embodiment, if the output current is the motor current in the power system, the preset current threshold can be set to 1.2I_nom, where I_nom is the average motor current when the clothes drying rod rises normally without any load or obstruction. When the drying rod rises to the upper limit position without stopping, the motor torque in the power system will increase significantly, and therefore the motor output current will also increase significantly. As mentioned above, when the output current of the power system does not exceed the preset current threshold, the drying rod is controlled to continue rising. At the same time, during the rising process, the drying rod can periodically, according to a preset time or when a preset condition is met, re-determine whether a trigger signal from the trigger element has been received; until the drying rod reaches the upper limit position. Under normal circumstances, if the triggering element is not faulty, when the drying rack moves from the second preset position to the upper limit position, the obstruction of the main unit or the ceiling will definitely exert a force exceeding the threshold on the pulley assembly, thus triggering the triggering element. Considering the possibility of triggering element failure, in the absence of a trigger signal, this embodiment can further consider the output current value of the power system and determine whether the drying rack has reached the top based on this output current. When the output current information of the power system exceeds the preset current threshold, the drying rack is immediately stopped. It can be seen that this embodiment provides a higher level of protection for the safe operation of the drying rack through the output current of the power system, and can avoid the situation where the drying rack hits the top due to the inability to determine that the drying rack has reached the upper limit position because of triggering element failure.

[0082] Therefore, the method in this embodiment can effectively prevent the drying rack from hitting the top.

[0083] The third position is located between the second preset position and the upper limit position, and may include the position when it is in the second preset position. When the drying rack is rising and in the third position, the trigger signal sent by the trigger can be periodically judged at a preset period, or it can be judged only a preset number of times (1 or more). If it is the latter, the time for each judgment can be preset in advance. In addition, the judgment can also be performed when a preset condition is met. This embodiment does not limit the judgment, and it can be set according to the actual use requirements.

[0084] In this embodiment, stroke calibration is performed before executing the above method to determine the upper and lower limit positions. The specific stroke calibration process can be as follows:

[0085] Sa, control the clothes drying rack rods to rise under no-load through the clothes drying rack power system;

[0086] Sb. Detect whether the trigger is triggered. When the main control module of the clothes drying machine receives the trigger signal sent by the trigger, it can be determined that the trigger has been triggered.

[0087] If so, proceed to step Sc;

[0088] If not, return to step Sa;

[0089] Sc. Control the drying rod of the drying machine to stop running through the power system of the drying machine; and detect the current position information of the drying rod through the position detection unit, and record the current position of the drying rod as the upper limit position P_max;

[0090] Sd. Control the drying rod of the drying machine to descend through the power system of the drying machine, calculate the descending stroke of the drying rod based on the position information detected by the position detection unit, and when the descending stroke reaches the preset stroke L, control the drying rod of the drying machine to stop running through the power system of the drying machine, and record the current position where the drying rod stops as the lower limit position P_min.

[0091] This embodiment realizes the calibration of the stroke based on the above steps Sa to Sd to ensure the accuracy of the subsequent operation control of the drying machine.

[0092] In this embodiment, the upper limit position is set as P_max, the lower limit position is set as P_min, the first preset position is P_max - x, and the second preset position is P_max - y, where x is the first distance and y is the second distance, and x is greater than y. For example, x is 10 cm and y is 1 cm. As Figure 3 shown, when controlling the drying rod to rise and run, the specific control process can be as follows:

[0093] T1. When receiving the control instruction for the drying rod to rise and run, control the drying rod to move upward through the power system of the drying machine, and at the same time obtain the real-time position information of the drying rod;

[0094] T2. Determine the current position P_curr of the drying rod according to the real-time position information of the drying rod. When the current position P_curr of the drying rod satisfies P_curr < P_max - x, that is, when it is in the first position process, enter step T3;

[0095] T3. Determine whether a trigger signal is received;

[0096] If yes, determine the stop position of the drying rod as the first preset position P_max - x, and control the drying rod to rise and run to the first preset position P_max - x and then stop running;

[0097] If not, enter step T4;

[0098] T4. Control the drying rod to continue to rise, and return to step T3 after one cycle, after a preset time, or when a preset condition is met, until the drying rod runs to the first preset position P_max - x, that is, when P_max - x ≤ P_curr < P_max - y (when the drying rod is in the second position), then enter step T5;

[0099] T5. Determine whether a trigger signal is received;

[0100] If so, then determine the drying rack's stopping position as the first preset position, control the drying rack to descend back to the first preset position, and then stop the operation;

[0101] If not, proceed to step T6;

[0102] T6. Control the drying rod to continue rising, and return to step T5 after one cycle, after a preset time, or when the preset conditions are met, until the drying rod runs to the second preset position P_max-y, that is, when P_curr satisfies P_curr≥P_max-y (the drying rod is in the third position), then proceed to step T7.

[0103] T7. Determine if a trigger signal has been received;

[0104] If so, the position where the drying rod stops is determined to be the upper limit position, the drying rod is controlled to stop at the upper limit position, and the current position P_curr of the drying rod is refreshed to P_max; in this case, the drying rod usually touches the host or ceiling after reaching the upper limit position, causing the trigger to be triggered. Therefore, after receiving the trigger signal, the drying rod is controlled to stop running.

[0105] If not, determine whether the current of the clothes drying rack motor exceeds the preset current threshold. If the motor current exceeds the preset current threshold, control the drying rack to stop running and refresh the current position P_curr of the drying rack to P_max. If the motor current does not exceed the preset current threshold, execute step T8.

[0106] T8. Control the drying rack to continue rising, and return to step T7 after one cycle, after a preset time, or if the preset conditions are met.

[0107] In summary, the clothes drying rack operation control method described in this embodiment determines the real-time position of the drying rack after receiving the drying rack operation control command, and acquires the trigger signal sent by the triggering element. Based on the current position information of the drying rack and the trigger signal, the method determines the position where the drying rack will stop. In this embodiment, the triggering element is located on the displacement path of the clothes drying rack's steering pulley assembly and can be triggered when the pulley assembly moves to the corresponding position, that is, when the pulley assembly deforms due to weight load. Based on this, the method in this embodiment combines the real-time position information of the drying rack and the trigger signal of the triggering element to limit the position of the drying rack. It considers both the position of the drying rack and changes in the drying rack due to load, effectively improving the reliability of the clothes drying rack's limit triggering. The dual-factor collaborative judgment method can effectively avoid accidents such as the drying rack hitting the top due to a single signal failure.

[0108] The steps described above in this embodiment are merely one implementation process. Those skilled in the art will understand that all or part of the steps in this embodiment can be implemented by a program instructing related hardware, and the corresponding program can be stored in a computer-readable storage medium. It should be noted that although the method operations of this embodiment are described in a specific order in the accompanying drawings, this does not require or imply that these operations must be performed in that specific order, or that all the shown operations must be performed to achieve the desired result. On the contrary, the described steps may be executed in a different order, some steps may be executed simultaneously, additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.

[0109] Example 2

[0110] This embodiment discloses a clothes drying rack operation control system, applied to a clothes drying rack. The basic structure of the clothes drying rack can be as shown in Embodiment 1; as follows: Figure 4 As shown in the figure, the clothes drying rack operation control system of this embodiment includes a control unit, a position detection unit, and a trigger.

[0111] In this embodiment, the position detection unit is connected to the control unit and is used to detect the real-time position information of the clothes drying rod and feed back the detected real-time position information to the control unit. In this embodiment, the position detection unit can be a Hall sensor, ultrasonic sensor, infrared distance sensor, laser sensor, etc. If a Hall sensor is used, it can be placed on the motor output shaft. The number of pulses output by the Hall sensor can detect the motor rotation, and based on this, the position of the clothes drying rod can be determined after appropriate calculation. If other types of sensors such as ultrasonic sensors, infrared distance sensors, and laser sensors are used, each type of sensor can achieve real-time detection of the clothes drying rod's position by being placed at the corresponding position on the clothes drying rack. These sensors can be placed on the clothes drying rod or the main unit to detect the distance between the clothes drying rod and the main unit, and the position of the clothes drying rod can be determined by the distance between the clothes drying rod and the main unit. This embodiment does not limit the type of position detection unit used, as long as it can achieve the function of detecting the position of the clothes drying rod.

[0112] The trigger is located on the main body of the clothes drying rack, for example, on the displacement path of the steering pulley assembly, and is triggered when the pulley assembly moves to the corresponding position; since the steering pulley assembly is installed on both sides inside the main body, the trigger located on the displacement path of the pulley assembly is also inside the main body of the clothes drying rack. Figure 2 As shown, the pulley assembly includes a pulley component 1 and an elastic component 2; wherein:

[0113] The pulley assembly provides steering for the cable, such as the steel wire rope 3, connecting the clothes drying rack to the drying rod. The pulley is slidably mounted on the main body of the clothes drying rack. Specifically, for each pulley, two grooves can be provided at the corresponding position on the main body. The axle 4 passing through the pulley is positioned on both ends of the two grooves. Based on this, the pulley can slide relative to the main body, i.e., generate displacement. The sliding of the pulley can be vertical, downward tilting, or horizontal, etc. In this embodiment, it is only necessary to ensure that the pulley can be displaced to the corresponding position of the trigger 5 on its displacement path after the force exceeds a threshold. Considering the current structure of the clothes drying rack, at least one pulley assembly can be provided at each end of the main body of the clothes drying rack. In this embodiment of the clothes drying rack, one end of the cable, such as the steel wire rope, is wound around a winding reel, and the other end extends downward after passing over the pulley and connects to the drying rod. Therefore, the pulley bears the weight of the drying rod.

[0114] The elastic element in the pulley assembly is connected to the main unit at one end and to the pulley assembly at the other end, specifically to the axle on the pulley assembly. For each pulley assembly, two elastic elements can be configured, one end of which is connected to both ends of the pulley assembly's axle, and the other ends of both elastic elements are fixedly connected to the main unit. The elastic element can be a tension spring. When the force on the pulley assembly does not exceed a preset threshold, the tension spring is in a reset state, and the pulley assembly is at position a (such as the highest position) under the tension of the tension spring. When the force on the pulley assembly is greater than or equal to the preset threshold, that is, when the load on the drying rod exceeds a certain value, the pulley assembly will be displaced, thereby driving the tension spring to stretch in the direction of its displacement. If the load on the drying rod disappears or decreases so that the force on the pulley assembly does not exceed the preset threshold, the pulley assembly will return to position a under the tension of the tension spring.

[0115] In this embodiment, the trigger can be a contact sensor or a non-contact sensor. The trigger being positioned on the pulley assembly's displacement path includes being positioned within the pulley assembly's displacement path and on both sides of the displacement path. When the trigger is a contact sensor, a microswitch can be used. When the trigger is a non-contact sensor, a photoelectric sensor, such as an infrared sensor, laser sensor, or ultrasonic sensor, can be used. When the trigger is a contact sensor, such as a microswitch, the pulley assembly needs to contact the microswitch to trigger it. The pulley assembly can contact the microswitch at one end of the axle, and the microswitch is located on the axle's displacement path. When the pulley assembly slides to the corresponding position, the axle end can contact the trigger plate of the microswitch. When the trigger is a photoelectric sensor, the photoelectric sensor includes a light emitting module and a light receiving module. The light emitting module and the light receiving module can be positioned on both sides of the pulley assembly's displacement path. When the pulley assembly slides to the corresponding position due to a force exceeding a threshold, it will block the light emitting module, preventing the light receiving module from receiving the corresponding light signal.

[0116] In this embodiment, the trigger is connected to the control unit and is used to send a trigger signal to the control unit when it is triggered. In this embodiment, the trigger is connected to the control unit and will generate a trigger signal, such as a high-level signal, a low-level signal, or a corresponding pulse signal, to the control unit when it is triggered by the pulley assembly. After receiving the trigger signal, the control unit can determine that the trigger is triggered by the pulley assembly.

[0117] In this embodiment, the control unit is connected to the power system of the clothes drying rack and is used to execute the clothes drying rack operation control method described in Embodiment 1, including:

[0118] Receive the control command for the clothes drying rack rod;

[0119] Obtain the real-time position information of the drying rack;

[0120] The trigger signal emitted by the triggering element is obtained. The triggering element is set on the main body of the clothes drying machine and is triggered when the pulley assembly is moved to the corresponding position.

[0121] The stopping position is determined based on the real-time position information of the drying rod and the trigger signal emitted by the triggering device;

[0122] According to the control command for the drying rack, the drying rack is controlled to stop when it reaches the designated stopping position.

[0123] The specific implementation process of each of the above steps can be shown in Example 1, and will not be repeated here.

[0124] In this embodiment, the control unit can be the controller originally installed on the main control module of the clothes drying machine host, or it can be a separately installed controller. If it is the latter, the controller needs to be connected to the main control module on the host so that the main control module controls the operating status of the clothes drying machine based on the trigger signal or clothes drying machine control signal sent by the control unit.

[0125] The system in this embodiment may also include a current detection unit, which is connected to the control unit and is used to detect the output current of the clothes drying rack's power system, such as the motor, and send the detected current information to the control unit. When the drying rod reaches the third position, the control unit obtains the current information detected by the current detection unit in real time. If no trigger signal is received from the triggering element, the control unit determines whether the output current of the motor exceeds a preset current threshold based on the current information. If it exceeds the threshold, the control unit stops the drying rod from running, ensuring that the drying rod can be stopped in time when the triggering element fails and cannot be triggered, causing the drying rod to hit the top.
