Description

Technical Field

[0001] This application relates to the field of home furnishing equipment technology, and more specifically, to a home furnishing equipment, a wire rope testing method, a clothes drying device, a medium, and a program product. Background Technology

[0002] Currently, there are no dedicated testing devices for the lifespan of steel wire ropes in existing smart home devices. To estimate the lifespan of steel wire ropes, a relatively static testing method is generally used, such as estimating the lifespan based on the number of times and duration of use of the home device. However, this method cannot take into account specific usage conditions, such as whether the weight of the home device exceeds the limit, resulting in very low accuracy of the estimated results and a high risk of misjudgment. Summary of the Invention

[0003] This application addresses the shortcomings of existing methods by proposing a home appliance, a steel wire rope testing method, a clothes drying device, a medium, and a program product to solve the technical problem of low accuracy in steel wire rope testing results obtained using relatively static methods in related technologies.

[0004] In one aspect, embodiments of this application provide a home appliance, including a main unit and a moving component connected by a wire rope, and a detection device for detecting the wire rope;

[0005] The main unit has a built-in motor and at least one winding spool connected to the motor for receiving the wire rope; the winding spool is provided with threaded grooves, and the wire rope is wound from the first end of the threaded groove to the second end of the threaded groove when it is wound into the winding spool.

[0006] The detection device includes a first detection switch, a second detection switch arranged near the first end of the threaded groove, and a detection unit arranged based on the drive shaft of the motor for acquiring rotation data of the drive shaft.

[0007] The first detection switch includes at least one of a first sub-detection switch located on the side of the host and triggered by the moving component, and a second sub-detection switch located near the second end of the threaded groove.

[0008] Secondly, embodiments of this application provide a method for detecting steel wire ropes, applied to the household equipment provided in the first aspect; the method includes:

[0009] In response to an instruction to control the movement of the moving component, the detection unit is invoked to obtain the rotation data of the drive shaft during the time period between the triggering of the first detection switch and the second detection switch;

[0010] The current deformation result of the wire rope is determined based on the preset first stroke information and the second stroke information determined by the rotation data.

[0011] In one possible embodiment, the step of invoking the detection unit to obtain the rotation data of the drive shaft during the time period when the first detection switch and the second detection switch are triggered includes at least one of the following:

[0012] In response to a triggering operation of the first detection switch when the moving component begins to descend, the detection unit is activated to begin acquiring rotational data of the drive shaft; in response to a triggering operation of the second detection switch when the moving component descends to the end of its travel, the detection unit is stopped, and rotational data of the drive shaft corresponding to the time period between the triggering of the first detection switch and the second detection switch is acquired.

[0013] In response to a triggering operation of the second detection switch when the moving component begins to rise, the detection unit is activated to begin acquiring rotational data of the drive shaft; in response to a triggering operation of the first detection switch when the moving component rises to the end of its travel, the detection unit is stopped, and rotational data of the drive shaft corresponding to the time period between the triggering of the first detection switch and the second detection switch is acquired.

[0014] In another possible embodiment, the first sub-detection switch and the second sub-detection switch include normally open switches; the triggering operation of the first detection switch includes at least one of the following:

[0015] When the moving component begins to descend, the moving component releases its resistance to the first sub-detection switch, and / or the wire rope releases its resistance to the second sub-detection switch at the start of release;

[0016] When the moving component rises to the end of its travel, the moving component abuts against the first sub-detection switch, and / or the wire rope abuts against the second sub-detection switch at the end of retrieval;

[0017] The second detection switch includes a normally open switch; the triggering operation of the second detection switch includes: when the moving component descends to the end of its travel, the wire rope abuts against the second detection switch at the end of its release, or when the moving component begins to rise, the wire rope releases its abutment against the second detection switch at the start of its retraction.

[0018] In yet another possible embodiment, the preset first travel information is obtained by performing at least one of the following operations:

[0020] If the moving component rises and the first detection switch is triggered, or if the moving component descends and the second detection switch is triggered, then the first travel information is obtained through the server.

[0021] The initial state includes at least one of the following: no load-bearing state and factory-shipped state.

[0022] In another possible embodiment, determining the current deformation result of the wire rope based on preset first stroke information and second stroke information determined through the rotation data includes:

[0023] Determine the travel difference between the current travel indicated by the second travel information and the initial travel indicated by the first travel information, the travel difference indicating the tension deformation of the wire rope during the full travel of the moving component's descent;

[0024] If the travel difference is not less than a preset threshold, then it is determined that the wire rope has deformed.

[0025] In one possible embodiment, after determining that the wire rope has deformed, the method further includes:

[0026] When responding to an instruction to control the movement of the moving component, the duration between the steel wire rope contacting the second detection switch and releasing the second detection switch is obtained;

[0027] The remaining life of the wire rope is determined based on the metal fatigue performance information related to the material of the wire rope, the stroke difference, and the duration.

[0028] Thirdly, embodiments of this application provide a clothes drying device, including a main unit and a movable drying rod assembly connected by a steel wire rope. The main unit is equipped with a control device, which includes a memory, a processor, and a computer program stored in the memory.

[0029] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, which, when executed by an electronic device, implements the steps of the wire rope detection method provided in the second aspect and any of its embodiments.

[0030] Fifthly, embodiments of this application provide a computer program product, including a computer program, characterized in that, when the computer program is executed by a processor, it implements the steps of the wire rope detection method provided in the second aspect and any embodiment thereof.

[0031] The beneficial technical effects of the technical solutions provided in this application include:

[0032] In a first aspect, embodiments of this application provide a home appliance comprising a main unit and a moving component connected by a wire rope, and a detection device for detecting the wire rope. Specifically, the main unit has a built-in motor and at least one winding spool connected to the motor; the winding spool is provided with a threaded groove for receiving the wire rope, and the wire rope winds from the first end of the threaded groove to the second end of the threaded groove when wound into the winding spool; the detection device includes a first detection switch, a second detection switch, and a detection unit based on the drive shaft of the motor. The design of the arrangement of the first and second detection switches is related to the travel distance of the moving component, which moves by winding and unwinding the wire rope. Based on this, the first detection switch may include at least one of a first sub-detection switch located on the side of the main unit and triggered by the moving component, and a second sub-detection switch located near the second end of the threaded groove; the second detection switch may include a detection switch located near the first end of the threaded groove.

Specifically, when responding to an instruction to control the movement of a moving component, the method can invoke a detection unit to acquire rotation data of the transmission shaft during the time interval between the triggering of a first detection switch and a second detection switch. Then, based on preset first stroke information and second stroke information determined from the rotation data, the current deformation result of the steel wire rope is determined. Compared to the prior art, the implementation of this application can dynamically detect the deformation of the steel wire rope during the movement of the moving component, and can be tailored to the specific usage of the home appliances, improving the effectiveness and accuracy of steel wire rope life detection.

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0051] Currently, there are no dedicated testing devices for the lifespan of steel wire ropes in smart home devices. To estimate the lifespan of steel wire ropes, a relatively static method is typically used, such as estimating the lifespan based on the number of times and duration of use. However, this method cannot consider specific usage scenarios, such as whether the weight of the device exceeds its limit, resulting in very low accuracy and a high risk of misjudgment. For example, with the development of electric clothes drying racks, to improve their lifespan, metal steel wire ropes are used to control the lifting and lowering of moving components. The focus on the lifespan of these wire ropes has shifted from initially defining it based on the factory-specified lifespan of the material to testing the lifespan of the steel wire ropes electrically. However, since clothes drying racks do not have dedicated components for testing steel wire ropes, the current method relies on a relatively static approach (based on the number of times and duration of use) to assess their lifespan. This method cannot consider actual usage scenarios, resulting in very low accuracy and a high risk of misjudgment.

[0052] In view of at least one of the above-mentioned technical problems or areas for improvement in the related technologies, this application proposes a home appliance, a steel wire rope testing method, a clothes drying device, a medium, and a program product. This solution improves the accuracy and effectiveness of steel wire rope life testing by configuring a simple and easy-to-install testing device on the home appliance and realizing dynamic testing of the steel wire rope during the lifting and lowering of the moving component.

[0053] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0054] The following is combined Figures 1-5 The home appliances provided in the embodiments of this application will be described.

[0055] Specifically, the home appliance may include a main unit 1, a moving component 2, and a detection device for detecting steel wire ropes. Optionally, the home appliance may be a smart clothes dryer or a smart curtain. Figure 4 As shown, the main unit 1 and the moving component 2 are connected by a steel wire rope 13. The movement of the moving component 2 (such as raising or lowering) can be controlled by controlling the extension and retraction of the steel wire rope 13. When the home appliance is a smart clothes drying rack (clothes drying equipment), the moving component 2 can be a movable drying rod assembly. When the home appliance is a smart curtain, the moving component 2 can be a component fixed to the end of the curtain fabric (moving up and down or left and right) to drive the curtain fabric to move.

[0056] The main unit 1 has a built-in motor 11 and at least one winding spool 12 connected to the motor 11 for storing the wire rope 13. Figures 1-3 The diagram shows a structure including two spools 12 and two wire ropes 13; it is understood that the number and layout of the spools 12 connected to the motor 11 can be adjusted according to actual needs, and this embodiment does not limit this. Optionally, the motor 11 and the spools 12 can be connected via a drive shaft (not shown).

[0057] Among them, such as Figures 1-3 As shown, each spool 12 is provided with a threaded groove for receiving the wire rope 13. When the wire rope 13 is wound into the spool 12, it winds from the first end of the threaded groove to the second end of the threaded groove.

[0058] The detection device includes a first detection switch, a second detection switch 32, and a detection unit.

[0059] In one feasible embodiment, the first detection switch includes a first sub-detection switch 311 disposed on the side of the host 1, such as Figure 5 As shown, the first sub-detection switch 311 can be an upper limit switch (such as a normally open switch) triggered by the moving component 2. During the lifting and lowering process of the moving component 2, if the moving component 2 is lifted to the position, the moving component 2 will abut against the first sub-detection switch 311; if the moving component 2 starts to descend, the moving component 2 will release the abutment against the first sub-detection switch 311.

[0060] In one feasible embodiment, the first detection switch includes a second sub-detection switch 312 disposed near the second end of the threaded groove, such as Figure 2 As shown, the second sub-detection switch 312 can be an upper limit switch (such as a normally open switch) triggered by the wire rope 13. During the lifting and lowering process of the moving component 2, if the moving component 2 is raised to the correct position, the retractable portion of the wire rope 13 will be completely wound into the winding shaft 12. At this time, the portion of the wire rope 13 exposed on the winding shaft 12 will abut against the second sub-detection switch 312. If the moving component 2 starts to descend, the retractable portion of the wire rope 13 will begin to be released from the winding shaft 12. At this time, the wire rope 13 will release its abutment against the second sub-detection switch 312.

[0061] Optionally, in order to improve the accuracy of wire rope detection and reduce the cost of configuring the detection device on home appliances (such as without disassembling parts), the detection device provided in this application embodiment may simultaneously include a first sub-detection switch 311 and a second sub-detection switch 312.

[0062] In one feasible embodiment, the second detection switch 32 can be positioned close to the first end of the threaded groove, such as... Figures 1-3 As shown, the second detection switch 32 can be a lower limit switch (such as a normally open switch) triggered by the wire rope 13. During the lifting and lowering process of the moving component 2, if the moving component 2 descends to the end of its travel, the retractable portion of the wire rope 13 will be completely released from the winding shaft 12, at which point the wire rope 13 will abut against the second detection switch 32; if the moving component 2 starts to rise, the retractable portion of the wire rope 13 will begin to wind into the winding shaft 12, at which point the wire rope 13 will release its abutment against the second detection switch 32.

[0063] In one feasible embodiment, the detection unit (not shown) is used to detect the length of the stroke using the Hall effect principle. It may include a magnet mounted on the drive shaft of the motor 11 and a magnetic induction sensor mounted on the magnet. When the drive shaft rotates, the magnet rotates accordingly. The magnetic induction sensor can accurately measure rotational data, including the number of rotations and speed, and then the stroke can be calculated based on the rotational data. The method for acquiring rotational data and calculating the stroke using the Hall effect principle can be found in related technologies and will not be elaborated upon here. Optionally, the detection unit may also include a photoelectric encoder, such as a sensor that converts the mechanical geometric displacement on the drive shaft into pulses or digital quantities through photoelectric conversion.

[0064] This application provides a detection device for detecting wire rope 13 based on the movement of the moving component 2. The detection device has a simple structure, is easy to install, and is beneficial for dynamic detection of wire rope 13 during the movement of the moving component 2.

[0065] Based on the same inventive concept, this application provides a method for detecting steel wire ropes, the flowchart of which is shown below. Figure 6 As shown. This method can be applied to the home appliances provided in the above embodiments, specifically including steps S101-S102:

[0066] S101: In response to the instruction to control the movement of the moving component, the detection unit is invoked to obtain the rotation data of the drive shaft during the time period between the triggering of the first detection switch and the second detection switch;

[0067] S102: Determine the current deformation result of the wire rope based on the preset first stroke information and the second stroke information determined by the rotation data.

[0068] Optionally, the moving component can be a movable component in a home appliance. In this application, the dynamic process of moving the moving component via a steel wire rope can be addressed. The movement can be in different directions depending on the type of home appliance; for example, in a clothes drying system, the moving component can be a drying rod assembly, and its movement can refer to lifting or lowering; in a smart curtain system, the moving component can be a component that moves the curtain fabric, and its movement can be lifting or lowering, or moving left or right.

[0069] Optionally, to improve resource utilization, the detection unit can be activated to collect and process data when dynamic detection of the wire rope is required.

[0070] Optionally, the start and end times of the time period determined by the triggering times of the first and second detection switches can be either the triggering time of the first detection switch or the triggering time of the second detection switch, depending on the direction of movement of the moving component. For example, assuming the home appliance is a clothes drying device and the moving component is a drying rod assembly, the time period for acquiring rotation data when the drying rod assembly is descending is determined by the start time of the triggering of the first detection switch and the end time of the triggering of the second detection switch; conversely, the time period for acquiring rotation data when the drying rod assembly is ascending is determined by the start time of the triggering of the second detection switch and the end time of the triggering of the first detection switch.

[0071] Optionally, the rotation data may include data used to calculate the travel distance, such as the number of rotations, the rotation speed, and the rotation time.

[0072] The first stroke information can be information pre-detected and stored locally, or information obtained from servers, manufacturers, third-party platforms, etc. Optionally, the first stroke information can be used to indicate the standard stroke of the moving component, that is, the actual stroke of the wire rope under normal use conditions (tension deformation is almost 0).

[0073] The deformation result can be measured by the tensile deformation to determine whether the deformation of the wire rope is within an acceptable range, so as to further predict the life of the wire rope based on the deformation result.

[0074] In a feasible embodiment, step S101 involves calling a detection unit to obtain rotation data of the drive shaft during the time period when the first and second detection switches are triggered, including one of steps A1-A2:

[0075] Step A1: In response to the triggering operation of the first detection switch when the moving component begins to descend, the detection unit is started to begin acquiring rotation data of the drive shaft; in response to the triggering operation of the second detection switch when the moving component descends to the end of its stroke, the detection unit is stopped, and the rotation data of the drive shaft corresponding to the time period between the triggering of the first and second detection switches is acquired.

[0076] Step A2: In response to the triggering operation of the second detection switch when the moving component begins to rise, the detection unit is started to begin acquiring rotation data of the drive shaft; in response to the triggering operation of the first detection switch when the moving component rises to the end of its stroke, the detection unit is stopped, and the rotation data of the drive shaft corresponding to the time period between the triggering of the first and second detection switches is acquired.

[0077] Optionally, step A1 above illustrates a scheme for collecting rotational data via a detection unit during the descent of the moving component, and step A2 above illustrates a scheme for collecting rotational data via a detection unit during the ascent of the moving component. The difference between the two schemes lies in the fact that the objects that trigger the start of data collection and the objects that trigger the stop of data collection are reversed.

[0078] Optionally, in terms of structural configuration, the moving component has a maximum movable stroke. For example, in clothes drying equipment, the drying rod assembly has a minimum lowerable height. However, in practical applications, the moving component may not always move to its maximum stroke. To improve the effectiveness of wire rope detection, reduce data processing complexity, and decrease the resources consumed by collecting rotation data through the detection unit, this application can perform detection on the entire wire rope, such as performing data analysis and processing on the process of the moving component moving to its maximum stroke. In one example, it can be determined whether the moving component will move to its maximum stroke by controlling the moving component's movement command; it can also be determined by the time consumed during the moving component's movement. For example, if the standard time required for the moving component to move to its maximum stroke is known in advance, and if after the moving component starts moving and triggers a detection switch, another detection switch is not triggered after a certain period of time exceeding the standard time, it indicates that the moving component may not need to move to its maximum stroke.

[0079] In one feasible embodiment, the first sub-detection switch and the second sub-detection switch include normally open switches; the triggering operation of the first detection switch includes at least one of the following triggering operations:

[0080] Trigger Operation 1: When the moving component begins to descend, the moving component releases its resistance to the first sub-detection switch.

[0081] Trigger Operation 2: When the moving component begins to descend, the wire rope releases its resistance to the second sub-detection switch at the start of the release.

[0082] Triggering operation 3: When the moving component rises to the end of its travel, the moving component abuts against the first sub-detection switch.

[0083] Triggering Operation 4: When the moving component rises to the end of its travel, the wire rope abuts against the second sub-detection switch at the end of the retraction.

[0084] Optionally, such as Figure 5 As shown, after the moving component is raised to its position, it can abut against the first sub-detection switch, and while the moving component remains in the top position, it continuously applies pressure to the first sub-detection switch. When the moving component begins to descend, it releases the pressure on the first sub-detection switch, causing the first sub-detection switch to return to its original state.

[0085] Optionally, such as Figure 2 As shown, when the entire retractable portion of the wire rope is wound into the reel, the portion protruding from the reel will abut against the second sub-detection switch. When the moving component begins to descend, the wire rope is released outwards, simultaneously releasing its abutment against the second sub-detection switch, causing the second sub-detection switch to return to its original state.

[0086] In one feasible embodiment, the second detection switch includes a normally open switch; triggering the second detection switch includes: the wire rope abutting the second detection switch at the end of release when the moving component descends to the end of its travel, or the wire rope releasing the abutment against the second detection switch at the start of retraction when the moving component begins to rise.

[0087] Optionally, such as Figures 1-3 As shown, when the moving component descends to the end of its travel, the wire rope is simultaneously released (the retractable portion has been completely unwound from the reel). At this point, the wire rope's exit position is low and will abut against the second detection switch. While the moving component remains in this position, the wire rope will continuously apply pressure to the second detection switch. When the moving component begins to rise, the wire rope simultaneously begins to wind into the reel. At this point, the wire rope's exit position will rise and release its abutment against the second detection switch.

[0088] In one feasible embodiment, the preset first travel information is obtained by performing at least one of the following operations 1-2:

[0089] Operation 1: When the home appliance is in the initial state, control the moving component to descend and call the detection unit to obtain the rotation data of the drive shaft during the time period between the triggering of the first detection switch and the second detection switch, and determine the first stroke information based on the rotation data; wherein, the initial state includes at least one of the unloaded state and the factory state.

[0090] Optionally, considering that wire rope wear may be due to excessive load, the first stroke information can be determined by collecting reference rotation data of the drive shaft in an unloaded state or in its factory condition. In one example scenario, during online operation, the current wire rope stroke data can be detected periodically or periodically in an unloaded state, and then compared with the stroke data detected in a loaded state to determine the deformation of the wire rope under the current usage condition of the home appliance.

[0091] Operation 2: If the moving component rises and the first detection switch is triggered, or the moving component descends and the second detection switch is triggered, then the first travel information is obtained through the server.

[0092] Optionally, considering that the first travel information and the second travel information can be compared using standard methods, and that the first travel information of home appliances of the same model and design structure is the same, the first travel information can also be obtained through the server. This first travel information can be obtained by performing the above operation 1 and then uploaded to the server, or it can be uploaded to the server by other home appliances, or it can be information that the manufacturer has set up in advance and stored in the server.

[0093] Optionally, to reduce the memory occupied by the home appliance's stored information and improve the effectiveness and accuracy of the wire rope detection results, the first stroke information can be obtained and processed after determining the maximum travel distance of the moving component. This first stroke information can also be dynamically updated, such as the first stroke information obtained by the home appliance itself at different times, or the first stroke information obtained by maintenance personnel adjusting for error data during background data analysis.

[0094] In a feasible embodiment, step S102 determines the current deformation result of the wire rope based on preset first stroke information and second stroke information determined by rotation data, including steps B1-B2:

[0095] Step B1: Determine the travel difference between the current travel indicated by the second travel information and the initial travel indicated by the first travel information. This travel difference indicates the tension deformation of the wire rope during the full travel of the moving component as it descends.

[0096] Step B2: If the stroke difference is not less than the preset threshold, it is determined that the wire rope has deformation.

[0097] Optionally, the current stroke (L) indicated by the second stroke information is determined by the rotation data. 上<―>下 When ), the initial trip (L) indicated by the first trip information can be obtained. 初 ), and calculate the difference between the two ΔL=(L 上<―>下 -L 初 This allows us to obtain the tensile deformation of the wire rope between the triggering of the first and second detection switches. Then, based on the specific parameters of different wire rope materials, we can obtain the corresponding maximum tensile deformation (preset threshold T). max When the travel difference is compared with the travel difference, it indicates that the tension of the wire rope is relatively serious. (Specifically, the travel difference can be compared with the value of the preset threshold.)

[0098] In a feasible embodiment, after determining that the wire rope has deformed, the wire rope detection method provided in this application further includes S103-S104:

[0099] S103: When responding to an instruction to control the movement of the moving component, acquire the duration between the wire rope contacting the second detection switch and the release of the second detection switch;

[0100] S104: Determine the remaining life of the wire rope based on the metal fatigue performance information, stroke difference, and duration related to the material of the wire rope.

[0101] Optionally, corresponding to the time period before the first and second detection switches are triggered in step S101, the duration obtained in step S103 considers the duration of the wire rope maintaining a certain tension. For example, for a clothes drying device, if step S101 obtains rotational data adapting to the descent of the drying rod assembly, then step S103 obtains the duration between the first moment when the drying rod assembly descends to the end of its stroke and the second moment when the drying rod assembly begins to rise.

[0102] Among them, the metal fatigue performance information related to the material of the wire rope can be obtained by referring to relevant technologies (metal fatigue refers to the process in which materials and components gradually develop local permanent cumulative damage at one or several places under cyclic stress or cyclic strain, and cracks or sudden complete fracture occur after a certain number of cycles). This application can estimate the remaining life of the wire rope based on the obtained performance information, stroke difference and duration, so as to remind the operator to replace the wire rope when the remaining life is short, and avoid affecting the normal use of home equipment due to wire rope breakage or severe wear.

[0103] Optionally, considering the simultaneous presence of the first and second sub-detection switches, since the objects triggering the first and second sub-detection switches are different, the triggering times may deviate. If the difference between the triggering times of the two switches is greater than a set threshold, it indicates that the tension deformation of the wire rope may be large. To reduce resource consumption caused by dynamic detection and to promptly detect problems related to the tension deformation of the wire rope, the system can be triggered to perform dynamic detection of the wire rope based on this judgment result. In one example, when the detection unit is called to collect rotation data in step S101, data can also be collected for the time periods corresponding to the triggering of the first and second sub-detection switches respectively. That is, when the first and second sub-detection switches are simultaneously deployed in the structure, two sets of rotation data corresponding to different or the same time periods can be collected. In subsequent processing stages, the triggering accuracy and data collection accuracy corresponding to the first and second sub-detection switches can be further analyzed based on the determined deformation results to adjust the reference data used for subsequent dynamic detection. If it is determined that the accuracy of the deformation result is higher when the rotation data collected during the time period between the triggering of the first sub-detection switch and the second detection switch is higher, then subsequent collection of rotation data can be based on the triggering of the first sub-detection switch.

[0104] Based on the same inventive concept, this application provides a wire rope detection device, the structural framework of which is shown in the schematic diagram below. Figure 7 As shown, it includes: a data acquisition module 101 and a result prediction module 102.

[0105] The data acquisition module 101 is used to respond to the instruction to control the movement of the moving component by calling the detection unit to acquire the rotation data of the transmission shaft during the time period between the triggering of the first detection switch and the second detection switch; the result prediction module 102 is used to determine the current deformation result of the wire rope based on the preset first stroke information and the second stroke information determined by the rotation data.

[0106] In one feasible embodiment, when the data acquisition module 101 is used to execute the call to the detection unit to acquire the rotation data of the drive shaft during the time period when the first detection switch and the second detection switch are triggered, it is specifically used for one of the following:

[0107] In response to a triggering operation of the first detection switch when the moving component begins to descend, the detection unit is activated to begin acquiring rotational data of the drive shaft; in response to a triggering operation of the second detection switch when the moving component descends to the end of its travel, the detection unit is stopped, and rotational data of the drive shaft corresponding to the time period between the triggering of the first detection switch and the second detection switch is acquired.

[0108] In response to a triggering operation of the second detection switch when the moving component begins to rise, the detection unit is activated to begin acquiring rotational data of the drive shaft; in response to a triggering operation of the first detection switch when the moving component rises to the end of its travel, the detection unit is stopped, and rotational data of the drive shaft corresponding to the time period between the triggering of the first detection switch and the second detection switch is acquired.

[0109] In one feasible embodiment, the first sub-detection switch and the second sub-detection switch include normally open switches; when the data acquisition module 101 is used to perform a triggering operation on the first detection switch, it is specifically used for at least one of the following:

[0110] When the moving component begins to descend, the moving component releases its resistance to the first sub-detection switch, or the wire rope releases its resistance to the second sub-detection switch when the release begins;

[0111] When the moving component rises to the end of its travel, the moving component abuts against the first sub-detection switch, or the wire rope abuts against the second sub-detection switch at the end of its retrieval.

[0112] In one feasible embodiment, the second detection switch includes a normally open switch. When performing a triggering operation on the second detection switch, the data acquisition module 101 is further configured to: abut the second detection switch at the end of release when the moving component descends to the end of its travel, or release the abutment against the second detection switch at the start of retraction when the moving component begins to rise.

[0113] In one feasible embodiment, the preset first travel information is obtained by performing at least one of the following operations:

[0114] When the home appliance is in its initial state, the moving component is controlled to rise or fall and the detection unit is invoked to obtain the rotation data of the drive shaft during the time period between the triggering of the first detection switch and the second detection switch, and the first stroke information is determined based on the rotation data.

[0115] If the moving component rises and the first detection switch is triggered, or if the moving component descends and the second detection switch is triggered, then the first travel information is obtained through the server.

[0116] The initial state includes at least one of the following: no load-bearing state and factory-shipped state.

[0117] In a feasible embodiment, when the result prediction module 102 determines the current deformation result of the wire rope based on preset first stroke information and second stroke information determined by the rotation data, it is specifically used for:

[0118] Determine the travel difference between the current travel indicated by the second travel information and the initial travel indicated by the first travel information, the travel difference indicating the tension deformation of the wire rope during the full travel of the moving component's descent;

[0119] If the travel difference is not less than a preset threshold, then it is determined that the wire rope has deformed.

[0120] In one feasible embodiment, after determining that the wire rope has deformed, the result prediction module 102 is further configured to:

[0121] When responding to an instruction to control the movement of the moving component, the duration between the steel wire rope contacting the second detection switch and releasing the second detection switch is obtained;

[0122] The remaining life of the wire rope is determined based on the metal fatigue performance information related to the material of the wire rope, the stroke difference, and the duration.
