Description

Technical Field

[0001] This application relates to the technical field of clothes drying racks, and more particularly to a method for calibrating the hanging weight parameters of a clothes drying rack. Background Technology

[0002] In the clothes drying rack industry, the motor is the core power component, and its performance consistency directly affects the clothes drying rack's rated load-bearing stop function.

[0003] In existing technologies, fixed rated current and shutdown current parameters are usually preset for the motors of clothes drying racks to ensure that they can operate normally without stopping under rated load; for example, clothes drying rack motors produced in the same batch are set with uniform current parameter standards when they leave the factory.

[0004] However, due to factors such as manufacturing processes, even motors from the same batch may have slight performance differences, and fixed current parameters cannot accommodate these individual variations. When a machine stops operating under its rated load, it usually requires disassembly and replacement of the motor. The entire replacement process is cumbersome and complex, especially for clothes drying racks with complex structures that are difficult to disassemble, which consumes a lot of labor costs. Moreover, the second motor cannot guarantee that it will not stop operating under its rated load, which means that the problem cannot be fundamentally solved, seriously affecting the user experience and the product's market competitiveness. Summary of the Invention

[0005] This application provides a method for calibrating the hanging load parameters of a clothes drying rack. By dynamically calibrating the hanging load parameters, it accurately adapts to the individual characteristics of the motor, avoids the problem of machine shutdown due to the rated hanging load caused by fixed parameters, eliminates the need to disassemble the machine and replace the motor, reduces labor costs and ensures the effect of use.

[0006] In a first aspect, this application provides a method for calibrating the hanging weight parameters of a clothes drying rack, comprising: determining the current hanging weight parameters based on an acquired initial hanging weight calibration parameter set of the clothes drying rack; acquiring the motor current of the clothes drying rack in the hanging weight calibration mode in real time, and determining whether the motor current is within the effective current range; and dynamically adjusting the current hanging weight parameters according to the determination result.

[0007] Furthermore, this method first determines the current load parameters based on initial parameters, then collects the motor current in calibration mode and judges its validity, and finally dynamically adjusts the parameters. This not only accurately adapts to the individual characteristics of the motor and solves the problem of accidental shutdown under rated load, but also ensures the accuracy of calibration and the stability of equipment operation.

[0008] In one possible implementation, determining the current load parameter based on the acquired initial load calibration parameter set of the clothes dryer specifically includes: acquiring the initial load calibration parameter set of the clothes dryer, wherein the initial load calibration parameter set includes a default current parameter and a default load calibration parameter; determining whether the default load calibration parameter is valid; if valid, determining the current load parameter based on the default load calibration parameter; if invalid, determining the current load parameter based on the default current parameter; wherein the default current parameter includes a default rated current and a default shutdown current, the default load calibration parameter includes a first shutdown current and a first load calibration multiple, and the current load parameter includes the current rated current, the current shutdown current, and the current load calibration multiple.

[0009] Furthermore, this setting prioritizes the use of historically valid calibration parameters to adapt to the individual characteristics of the motor, and switches to default parameters when invalid to ensure basic operation. This not only solves the problem of accidental shutdown due to rated load caused by fixed parameters, but also continues the results of historical calibration, simplifies the process, and balances the stability of equipment operation, calibration accuracy and ease of operation, while also reducing the technical implementation and maintenance costs.

[0010] Furthermore, by clearly defining the specific composition of the default current parameters, default load calibration parameters, and current load parameters, this setting provides a clear basis for judging the validity of parameters, accurately adapts to the individual characteristics of the motor, ensures normal operation under rated load, and gives clear objectives for subsequent current acquisition and dynamic parameter adjustment.

[0011] In one possible implementation, determining whether the default load calibration parameter is valid, and if valid, determining the current load parameter based on the default load calibration parameter; if invalid, determining the current load parameter based on the default current parameter, specifically includes: determining whether the first shutdown current is a preset shutdown current value; if the first shutdown current is not a preset shutdown current value, determining that the default load calibration parameter is valid; otherwise, determining that the default load calibration parameter is invalid; when the default load calibration parameter is invalid, using the default rated current as the current rated current and the default shutdown current as the current shutdown current; when the default load calibration parameter is valid, updating the current shutdown current to the first shutdown current, and determining whether the first load calibration multiple is a preset load calibration multiple value; if not, updating the current load calibration multiple to the first load calibration multiple; otherwise, updating the current load calibration multiple to a preset target load calibration multiple; and determining the current rated current based on the updated current shutdown current and the updated load calibration multiple.

[0012] Furthermore, this setting determines the validity of the default load calibration parameters by using the first shutdown current as the core. When valid, it adapts the personalized parameters; when invalid, it enables the default parameters. At the same time, it flexibly handles the load calibration multiple and derives the rated current. This not only accurately matches the individual characteristics of the motor and avoids accidental shutdown due to the rated load, but also ensures the stable operation of the equipment's basic structure, balancing calibration accuracy with process simplicity.

[0013] In one possible implementation, before acquiring the motor current of the clothes drying rack in the load calibration mode in real time, the method further includes: controlling the clothes drying rack to run to the lower limit position, and starting the load calibration mode after detecting the rated weight of the clothes drying rack and receiving a start command.

[0014] Furthermore, this setup first fixes the clothesline to the lower limit to unify the initial mechanical state, and then confirms the rated load to simulate a real working scenario. This provides a stable and standard calibration basis for subsequent current acquisition, effectively avoiding calibration deviations caused by position differences and improper loads, and improving the accuracy and reliability of load parameter calibration.

[0015] In one possible implementation, the real-time acquisition of the motor current of the clothes drying rack in the load calibration mode specifically includes: when the clothes drying rack performs an upward operation in the load calibration mode, determining whether the upward duration of the clothes drying rack exceeds a first preset duration; if so, acquiring the motor current of the clothes drying rack in real time at preset time intervals; determining whether the upward duration of the clothes drying rack exceeds a second preset duration; if so, stopping the acquisition of the motor current of the clothes drying rack.

[0016] Furthermore, this setting skips the current fluctuations during the motor startup phase by using a first preset duration and a second preset duration to control the upper limit of data acquisition. It collects the motor current during the stable phase at fixed intervals, which avoids interference from invalid data and ensures that a sufficient number of valid samples are collected, thus balancing calibration accuracy and process efficiency.

[0017] In one possible implementation, determining whether the motor current is within the effective current range specifically includes: calculating the average motor current corresponding to the motor current based on the obtained sum of motor currents and current count values; determining whether the average motor current is not less than the minimum effective current within the effective current range, and whether the average motor current is not greater than the maximum effective current within the effective current range; if so, determining that the motor current is within the effective current range; otherwise, determining that the motor current is not within the effective current range.

[0018] Furthermore, this setting eliminates instantaneous fluctuation interference by calculating the average motor current and then accurately determines the effective current range threshold. This not only ensures the stability of the current judgment but also accurately filters out valid data that meets the rated load, providing a reliable basis for subsequent parameter adjustments and improving calibration accuracy.

[0019] In one possible implementation, dynamically adjusting the current load parameters based on the judgment result specifically includes: when the motor current is within the effective current range, updating the default load calibration parameters based on the motor current; when the motor current is not within the effective current range, updating the default load calibration parameters based on the factory-preset backup shutdown current value; and dynamically adjusting the current load parameters based on the updated default load calibration parameters.

[0020] Furthermore, this setting updates the default load calibration parameters according to the effectiveness of the motor current in different scenarios. When the current is effective, the real-time current is used, and when it is ineffective, the backup shutdown current is used. The current load parameters are then dynamically adjusted to ensure that the parameters are adapted to the actual state of the motor and can cope with abnormal situations, thus balancing calibration accuracy and equipment operation stability.

[0021] In one possible implementation, updating the default load calibration parameters based on the motor current specifically includes: obtaining the current load calibration multiple in the current load parameters, calculating the product of the motor current and the current load calibration multiple, and updating the first shutdown current in the default load calibration parameters to the product.

[0022] Furthermore, this setting updates the first shutdown current by multiplying the current load calibration multiple by the motor current, ensuring that the default load calibration parameters accurately match the real-time operating status of the motor, and ensuring that the shutdown current matches the rated load requirement. This further improves the accuracy of load protection and avoids accidental shutdowns or protection failures.

[0023] In one possible implementation, dynamically adjusting the current load parameter based on the updated default load calibration parameter specifically includes: determining whether the updated default load calibration parameter is valid; if the updated default load calibration parameter is invalid, updating the current load parameter to the default current parameter; if the updated default load calibration parameter is valid, updating the current load parameter based on the updated default load calibration parameter.

[0024] Furthermore, this setting verifies the validity of the updated default load calibration parameters. If invalid, it reverts to the default current parameters; if valid, it updates in conjunction with the backup shutdown current value. This ensures the reliability of parameter adjustments while also handling abnormal situations, balancing equipment operational stability with load calibration accuracy. In one possible implementation, updating the current load-bearing parameters based on the updated default load-bearing calibration parameters specifically includes: updating the current shutdown current in the current load-bearing parameters based on the first shutdown current in the updated default load-bearing calibration parameters; determining whether the first load-bearing calibration multiple is a preset load-bearing calibration multiple threshold; if so, updating the current load-bearing calibration multiple in the current load-bearing parameters to a preset target load-bearing calibration multiple; if not, updating the current load-bearing calibration multiple to the first load-bearing calibration multiple; and updating the current rated current in the current load-bearing parameters based on the updated current load-bearing calibration multiple and the current shutdown current.

[0025] Furthermore, this setting updates the current shutdown current, flexibly adapts to the load calibration multiple, and derives the rated current. By combining the backup shutdown current value with the effective calibration parameters, it ensures that the current load parameters match the actual state of the equipment, avoids the impact of abnormal multiples, and balances calibration accuracy and operational stability.

[0026] This application provides a method for calibrating the hanging weight parameters of a clothes drying rack, which has the following advantages compared with the prior art: This method determines the current load parameters based on the initial load calibration parameter set of the clothes drying rack; it acquires the motor current of the clothes drying rack in real time under load calibration mode and determines whether the motor current is within the effective current range; based on the determination result, it dynamically adjusts the current load parameters. Compared with the prior art, the technical solution of this application, through the process of determining the current load parameters based on the initial parameter set, acquiring and judging the effectiveness of the motor current in real time, and dynamically adjusting the parameters, can accurately adapt to the individual performance differences of motors in the same batch. Compared with the drawbacks of the prior art that relies on fixed parameters, requires disassembly and replacement of the motor when problems occur, and still has no guarantee after replacement, this method does not require disassembly of the equipment. It can rematch the shutdown current value through calibration operation, which not only solves the problem of shutdown under rated load, but also saves the cumbersome disassembly and replacement of the motor, greatly reducing labor costs. At the same time, it ensures that the clothes drying rack operates stably under rated load after adjustment, fundamentally improving the reliability of the product and the user experience.

Example 1, see Figure 1 , Figure 1 This is a flowchart illustrating one embodiment of a method for calibrating the hanging weight parameters of a clothes drying rack provided in this application. Figure 1 As shown, the method includes steps 101-103, as detailed below: Step 101: Determine the current hanging weight parameters based on the acquired initial hanging weight calibration parameter set of the clothes drying rack.

[0037] In one embodiment, an initial load calibration parameter set for the clothes drying rack is obtained, wherein the initial load calibration parameter set includes default current parameters and default load calibration parameters.

[0038] Specifically, when the clothes drying rack is detected to be powered on, the parameters of the clothes drying rack are initialized, and the initial load calibration parameter set of the clothes drying rack is obtained from the storage module.

[0039] Specifically, the storage module includes, but is not limited to, a FLASH module.

[0040] Specifically, the default current parameters include the default rated current and the default shutdown current; the default rated current and the default shutdown current are the reference current values ​​pre-stored when the clothes dryer leaves the factory.

[0041] Specifically, the default hanging weight calibration parameters include a first shutdown current and a first hanging weight calibration multiple; wherein, the first shutdown current can be understood as the shutdown current generated and stored during the historical calibration process, and the first shutdown current is pre-stored as a preset invalid identifier value when the clothes dryer leaves the factory; the first hanging weight calibration multiple is a coefficient used to correlate the shutdown current and the rated current calculation.

[0042] In one embodiment, it is determined whether the default load calibration parameter is valid. If it is valid, the current load parameter is determined based on the default load calibration parameter. If it is invalid, the current load parameter is determined based on the default current parameter.

[0043] Specifically, the current load parameters include the current rated current, the current shutdown current, and the current load calibration multiple.

[0044] In one embodiment, when determining whether the default load calibration parameter is valid, the first shutdown current is determined to be a preset shutdown current value. If the first shutdown current is not a preset shutdown current value, the default load calibration parameter is determined to be valid; otherwise, the default load calibration parameter is determined to be invalid.

[0045] Specifically, the preset shutdown current value is the invalid current value preset at the factory; when the current is less than the preset shutdown current value, an invalid flag value of 0 is set accordingly; preferably, the invalid flag value of 0 is used to determine whether the first shutdown current comes from a previous valid calibration operation.

[0046] Specifically, the validity of the first shutdown current is determined by judging whether the first shutdown current is a preset shutdown current value.

[0047] Specifically, if the first shutdown current is not equal to the preset shutdown current value, it means that the parameter is valid data stored after historical calibration, and the corresponding default load calibration parameter is valid as a whole; if it is equal to the preset shutdown current value, it means that the first shutdown current has not been effectively calibrated or that the default load calibration parameter is invalid as a whole when starting for the first time; this design can avoid using invalid or uninitialized calibration data and ensure the accuracy of subsequent parameter determination.

[0048] In one embodiment, when the default load calibration parameter is invalid, the default rated current is used as the current rated current, and the default shutdown current is used as the current shutdown current.

[0049] Specifically, when the default load calibration parameters are invalid, the initially set default current parameters will be used directly as the current load parameters, i.e., the current rated current = the default rated current, and the current shutdown current = the default shutdown current. This ensures that the factory default current parameters are used first when there is no valid calibration data, which can guarantee the basic overload shutdown protection function of the clothes drying rack and provide the basic operating conditions for possible subsequent calibration operations, avoiding the equipment from failing to work properly due to missing parameters.

[0050] In one embodiment, when the default load calibration parameter is valid, the current shutdown current is updated to the first shutdown current, and it is determined whether the first load calibration multiple is a preset load calibration multiple value. If not, the current load calibration multiple is updated to the first load calibration multiple; otherwise, the current load calibration multiple is updated to a preset target load calibration multiple. Based on the updated current shutdown current and the updated load calibration multiple, the current rated current is determined.

[0051] Specifically, when the default load calibration parameter is valid, it means that the first shutdown current is valid calibration data. Therefore, the current shutdown current is directly updated to the first shutdown current to ensure that the verified shutdown protection reference value is used.

[0052] Specifically, it is determined whether the first load calibration multiple is the preset load calibration multiple value. If it is not the preset load calibration multiple value, it means that the first load calibration multiple is a valid calibration value and is directly used as the current load calibration multiple value. If it is the preset load calibration multiple value, the factory preset target load calibration multiple value is used to avoid subsequent calculation errors due to invalid multiple values.

[0053] Preferably, the preset load calibration multiple is 0; the target load calibration multiple is 1.2.

[0054] Specifically, the updated current shutdown current and the updated load calibration multiple are substituted into the preset rated current calculation formula to determine the current rated current; wherein, the rated current calculation formula is: rated current = shutdown current / load calibration multiple.

[0055] Step 102: Obtain the motor current of the clothes drying rack in real time under the load calibration mode, and determine whether the motor current is within the effective current range.

[0056] In one embodiment, the clothes drying rack is controlled to move to the lower limit position. After detecting the rated weight of the clothes drying rack and receiving a start command, the weight calibration mode is started.

[0057] Specifically, moving the clothes drying rack to its lower limit is to ensure a consistent initial mechanical state for calibration. Since the load on the clothes drying rack's motor is affected by the position of the clothes drying rack, there are differences in mechanical resistance at different heights during the ascent. By fixing the clothes drying rack to its lower limit, fluctuations in mechanical resistance caused by different positions can be eliminated, ensuring a consistent initial mechanical environment for each calibration and making subsequent load determination based on motor current more accurate.

[0058] Specifically, testing the rated load of the clothes drying rack is to simulate a real rated load scenario. Only when the rated load is loaded can calibration be initiated to obtain current data that is strongly correlated with the rated load. This provides an accurate benchmark for subsequent judgment on whether the load is overloaded, i.e., when the current exceeds the current threshold corresponding to the rated load, and the machine is stopped.

[0059] In one embodiment, the real-time acquisition of the motor current of the clothes drying rack in the load calibration mode specifically includes: when the clothes drying rack performs an upward operation in the load calibration mode, determining whether the upward time of the clothes drying rack exceeds a first preset time; if so, acquiring the motor current of the clothes drying rack in real time at preset time intervals; determining whether the upward time of the clothes drying rack exceeds a second preset time; if so, stopping the acquisition of the motor current of the clothes drying rack.

[0060] Specifically, the preset time interval is 2ms, the first preset duration is 2s, and the second preset duration is 3s.

[0061] Specifically, after the clothes drying rack enters the load calibration mode and performs the lifting operation, the timing module begins to accumulate the lifting time. When the lifting time exceeds the first preset time, the motor current of the clothes drying rack is triggered to collect data. According to the preset time interval, the motor current of the clothes drying rack is periodically read by the motor current sensor and stored in the buffer. This is to skip the current fluctuations during the motor start-up phase, such as the large current at the moment of start-up, to ensure that the current data collected is from the stable operation phase, thereby improving the accuracy of the calibration.

[0062] Specifically, while collecting current at time intervals, the timing module continuously accumulates the rising time. When the rising time exceeds the second preset time, a stop collection command is sent to the current sensor, and the timer is turned off. This is to control the upper limit of the collection cycle, avoid unlimited collection due to mechanical failure, ensure that enough effective current samples are obtained, and prevent excessive consumption of system resources.

[0063] Specifically, when collecting the motor current of the clothes drying machine at preset time intervals, the multiple sets of motor currents are accumulated to obtain the total motor current corresponding to the motor current; and the counting module is activated to record the number of times the motor current of the clothes drying machine is collected to obtain the current count value.

[0064] In one embodiment, when determining whether the motor current is within the effective current range, the average motor current corresponding to the motor current is calculated based on the obtained sum of motor currents and current count value; it is then determined whether the average motor current is not less than the minimum effective current within the effective current range and whether the average motor current is not greater than the maximum effective current within the effective current range; if so, the motor current is determined to be within the effective current range; otherwise, the motor current is determined not to be within the effective current range.

[0065] Specifically, the sum of the motor currents and the current count value are input into a preset formula for calculating the average motor current to obtain the average motor current. The formula for calculating the average motor current is: Average motor current = Sum of motor currents ÷ Current count value. By calculating the average of the collected motor currents, the interference of single current fluctuations can be eliminated, and the accuracy of the motor current can be avoided due to current peaks caused by instantaneous electromagnetic interference.

[0066] Specifically, the effective current range includes the minimum effective current and the maximum effective current. The effective current range is determined by a large number of rated load tests during the product development stage and is a threshold for distinguishing between normal load current and abnormal current.

[0067] Specifically, the calculated average motor current is compared with the effective current range. If the average motor current is not less than the minimum effective current within the effective current range, and the average motor current is not greater than the maximum effective current within the effective current range, it indicates that the current motor current is within the normal fluctuation range under the rated load, and is determined to be within the effective current range. If the average motor current is less than the minimum effective current or greater than the maximum effective current, it is determined to be outside the effective current range. This step, through the determination of a clearly defined numerical range, achieves accurate identification of the load status, providing a reliable basis for subsequent dynamic adjustment of the load parameters.

[0068] Step 103: Based on the judgment result, dynamically adjust the current load parameters.

[0069] In one embodiment, when the motor current is within the effective current range, the default load calibration parameters are updated based on the motor current.

[0070] In one embodiment, when updating the default load calibration parameters based on the motor current, the product of the motor current and the current load calibration multiple is calculated by obtaining the current load calibration multiple in the current load parameters, and the first shutdown current in the default load calibration parameters is updated to the product.

[0071] Specifically, after determining that the motor current is within the valid range, the system will retrieve the determined current load calibration multiple from the parameter cache of the current system operation. After retrieval, the current load calibration multiple will be temporarily stored in the arithmetic register to prepare for subsequent multiplication operations, ensuring that the obtained current load calibration multiple is a valid value for the current motor state in the system.

[0072] Specifically, the motor current refers to the previously collected and verified average motor current, which is stored in the data buffer. The internal calculation unit multiplies the average motor current with the temporarily stored current load calibration multiple to update the first shutdown current in the default load calibration parameters. By adapting the multiple to the individual characteristics of the motor, the calculation result becomes a precise shutdown current benchmark that fits the motor, solving the problem of mismatch between the fixed shutdown current and the motor difference in the prior art.

[0073] In one embodiment, when the motor current is not within the effective current range, the default load calibration parameters are updated based on the factory-preset backup shutdown current value.

[0074] Specifically, when updating the default load calibration parameters based on the factory-preset backup shutdown current value, the first shutdown current in the default load calibration parameters is updated to the backup shutdown current value.

[0075] In one embodiment, after updating the first shutdown current in the default load calibration parameters, the clothes dryer will also prompt the user via voice to indicate that the load calibration is complete.

[0076] Specifically, the voice prompt methods include, but are not limited to, buzzers and voice broadcasts.

[0077] In one embodiment, the current load parameters are dynamically adjusted based on the updated default load calibration parameters.

[0078] In one embodiment, when dynamically adjusting the current load parameter based on the updated default load calibration parameter, it is determined whether the updated default load calibration parameter is valid; if the updated default load calibration parameter is invalid, the current load parameter is updated to the default current parameter; if the updated default load calibration parameter is valid, the current load parameter is updated based on the updated default load calibration parameter.

[0079] Specifically, it is determined whether the first shutdown current in the updated default load calibration parameters is a preset shutdown current value. If so, the default load calibration parameters are determined to be invalid; otherwise, the default load calibration parameters are determined to be valid.

[0080] Specifically, when the updated default load calibration parameters are invalid, the current shutdown current is updated to the default shutdown current, and the current rated current is updated to the default rated current.

[0081] Specifically, when the updated default load calibration parameters are determined to be invalid, the parameter rollback logic is activated, and the current rated current and current shutdown current of the current load parameters are replaced with the corresponding default values, so that the clothes dryer can switch back to the normal operation mode based on the default parameters, avoiding the failure of the protection function due to invalid calibration parameters and ensuring that the equipment can still operate normally.

[0082] In one embodiment, when updating the current load parameter based on the updated default load calibration parameter, the current shutdown current in the current load parameter is updated based on the first shutdown current in the updated default load calibration parameter; it is determined whether the first load calibration multiple is a preset load calibration multiple value; if so, the current load calibration multiple in the current load parameter is updated to a preset target load calibration multiple; if not, the current load calibration multiple is updated to the first load calibration multiple; and the current rated current in the current load parameter is updated based on the updated current load calibration multiple and the current shutdown current.

[0083] Specifically, when updating the current shutdown current in the current load parameters based on the first shutdown current in the updated default load calibration parameters, the current shutdown current is directly updated to the first shutdown current in the updated default load calibration parameters.

[0084] Specifically, the updated current load calibration multiple and the current shutdown current are substituted into the preset rated current calculation formula to obtain the target rated current, and the current rated current in the current load parameters is updated to the target rated current.

[0085] Specifically, the updated current load parameters are synchronously written into the running cache to ensure that the adapted parameters are directly called when the clothes dryer runs, thus achieving precise matching between the motor and the load protection.

[0086] The following is an example illustrating the specific implementation steps of a method for determining the hanging weight parameter of a clothes drying rack according to an embodiment of this application: Assuming a certain model of clothes drying rack has a rated hanging weight (8kg), default rated current (1.5A), default shutdown current (1.8A), standby shutdown current (2.0A), first shutdown current (0.5A), first hanging weight calibration multiple (0.8), preset shutdown current value (0A), preset hanging weight calibration multiple value (0), first preset duration (1 second), second preset duration (3 seconds), effective current range (1A-3A), and preset target hanging weight calibration multiple (1.2), the specific implementation steps for calibrating its hanging weight parameters are as follows: When the clothes dryer is powered on, the main control board automatically reads the initial load calibration parameter set from the FLASH storage module, obtaining the default current parameters (default rated current (1.5A), default shutdown current (1.8A)) and default load calibration parameters (first shutdown current (0.5A) (valid data after historical calibration), first load calibration multiple (0.8)). It then checks if the first shutdown current (0.5A) is the preset shutdown current value (0A). Since the first shutdown current (0.5A) is not the preset shutdown current value (0A), the default load calibration parameters are deemed valid. At this point, the current shutdown current is... Update to the first shutdown current (0.5A); determine whether the first load calibration multiple (0.8) is the preset load calibration multiple (0). Since the first load calibration multiple (0.8) is not the preset load calibration multiple (0), directly set the current load calibration multiple to the first load calibration multiple (0.8); and calculate the current rated current according to the formula: rated current = shutdown current / load calibration multiple, i.e. 0.5A ÷ 0.8 = 0.625A. At this time, the current load parameters are determined as the current rated current (0.625A), the current shutdown current (0.5A), and the current load calibration multiple (0.8).

[0087] The main control board of the clothes drying rack sends a downward command to drive the clothesline downward. When the clothesline touches the lower limit microswitch, the main control board immediately cuts off the downward current to the motor, and the clothesline stops at the lower limit. After the user hangs an 8kg rated weight on the clothesline, the main control board switches to the load calibration mode and sends an upward command to drive the clothesline upward. At the same time, a timer is started to accumulate the upward time. When the timer shows that the upward time has reached the first preset time of 1 second, the main control board starts current acquisition: at an interval of 2 milliseconds, the current sensor collects the motor current in real time, and records the number of acquisitions as the current count, and simultaneously records the motor current of each acquisition. The current is collected until the timer displays the rising time reaches the second preset time of 3 seconds. At this time, the main control board immediately stops current acquisition and sends a stop command. The clothes drying rod stops rising and the data acquisition stage ends. At this time, the total motor current is 1200A and the current count value is 1000. The average motor current is calculated as follows: total motor current (1200A) ÷ current count value (1000) = 1.2A. The calculated average motor current is compared with the preset effective current range (1A-3A). Since the average motor current (1.2A) is within the preset effective current range (1A-3A), the motor current is determined to be valid.

[0088] Obtain the current load calibration multiple (0.8) from the current load parameters. Calculate the updated first stop current as 1.2A × 0.8 = 0.96A using the formula: First stop current = Average motor current × Current load calibration multiple. Write the updated first stop current to the FLASH storage area, overwriting the original first stop current (0.5A), thus completing the update of the default load calibration parameters. Then, determine whether the updated first stop current (0.96A) is the preset stop current value (0A). Since the updated first stop current (0.96A) is not the preset stop current value (0A), the updated default... The load calibration parameters are confirmed to be valid. At this time, the current shutdown current is updated to the updated first shutdown current (0.96A). Since the first load calibration multiple is (0.8), which is not the preset load calibration multiple (0), the current first load calibration multiple is updated to the first load calibration multiple of (0.8). Then, according to the formula: rated current = shutdown current / load calibration multiple, the current rated current is calculated to be 0.96A ÷ 0.8 = 1.2A. The adjusted current load parameters are: current rated current (1.2A), current shutdown current (0.96A), and current load calibration multiple (0.8).

[0089] The main control board writes the adjusted current load parameters into the operating cache, and the clothes dryer automatically switches to normal operating mode. In subsequent use, when the motor current exceeds the current shutdown current (0.96A), the equipment triggers overload shutdown protection. When the current is around the current rated current (1.2A), it is determined to be in normal operating condition under rated load, thus avoiding accidental shutdown.
