Description

Technical Field

[0001] The present invention relates to the technical field of equipment detection, and in particular to a wear detection method, device, equipment, medium, program product and household electrical appliance. Background Art

[0002] Household appliances like blenders have built-in cutting tools. Over time, these tools will gradually wear out due to the high frequency of cutting and grinding ingredients. This wear can not only lead to reduced performance, such as less fine grinding and reduced mixing efficiency, but can also affect the lifespan and safety of the appliance. Therefore, regularly monitoring tool wear and taking appropriate maintenance measures (such as timely tool replacement and selecting the appropriate hardness of ingredients) are crucial to maintaining the optimal operation of household appliances.

[0003] Currently, tool wear detection relies primarily on subjective judgment or periodic replacement strategies, lacking objective, real-time detection methods. Consequently, existing techniques attempt to estimate tool wear by recording tool usage time. However, these techniques fail to account for variations in the hardness of the material being processed and the characteristics of the tool material. This leads to significant errors in these results. This inability to clearly determine whether a tool needs replacement can lead to excessive wear or premature replacement. Summary of the Invention

[0004] In view of this, the present invention provides a wear detection method, device, equipment, medium, program product and household appliance to solve the problem of being unable to accurately detect the degree of tool wear.

[0005] In a first aspect, the present invention provides a wear detection method, which includes: controlling a light emitting module to emit a light source to a detection target, and obtaining a first light intensity measured by the light receiving module after the light receiving module receives the reflected light of the detection target; determining a light compensation parameter according to a current detection environment, and adjusting the first light intensity based on the light compensation parameter to obtain a second light intensity; determining a first degree of wear of the detection target according to the second light intensity and a reference light intensity determined in advance in an unworn state.

[0006] The wear detection method provided by the present invention emits a light source toward a detection target, obtains a first light intensity of light reflected from the detection target, adjusts the first light intensity based on a light compensation parameter determined in the current detection environment to obtain a second light intensity, and determines a first degree of wear of the detection target based on the second light intensity and a reference light intensity in an unworn state. By utilizing optical detection principles, the present invention can detect the wear of a tool based on physical structures such as the flatness, roughness, or defects on the tool surface. This reduces human misjudgment and allows detection based on the actual characteristics of the tool, improving detection accuracy, avoiding excessive tool wear or premature replacement, saving costs for users, and ultimately improving user satisfaction and experience.

[0007] In an optional embodiment, a light compensation parameter is determined according to the current detection environment, and the first light intensity is adjusted based on the light compensation parameter to obtain the second light intensity, including: in the current detection environment, when a light source is emitted to a reference target and reflected light from the reference target is received, a third light intensity of the reflected light is obtained; a ratio of the third light intensity to the reference light intensity is calculated to obtain the light compensation parameter; and a product of the first light intensity and the light compensation parameter is calculated to obtain the second light intensity.

[0008] The present invention can achieve dynamic calibration of wear detection by determining the light compensation parameters under the current detection environment, eliminate the interference of the environment on optical detection, and improve the accuracy of optical detection.

[0009] In an optional embodiment, a first degree of wear of the detection target is determined based on the second light intensity and a reference light intensity determined in advance in an unworn state, including: calculating the actual intensity difference between the reference light intensity and the second light intensity, and calculating the ratio of the actual intensity difference to the reference light intensity to obtain the actual intensity difference ratio; determining the actual wear rate based on the correspondence between the actual intensity difference ratio and a preset intensity difference ratio and the wear rate; comparing the actual wear rate with a first preset warning threshold to determine a first degree of wear, which is a first degree of wear, a second degree of wear, or a third degree of wear.

[0010] The present invention determines the degree of wear of the detection target based on the current light intensity and the reference light intensity. It can quantify the influence of the physical structure of the tool surface, such as flatness, roughness or defects, on the reflected light, and accurately and intuitively judge whether the tool surface is worn and the specific degree of wear. The user can determine whether to replace the tool based on the judged degree of wear, avoiding the problem of excessive wear of the tool or premature replacement.

[0011] In an optional embodiment, after determining the first wear degree of the detection target based on the second light intensity and the reference light intensity determined in advance in an unworn state, it also includes: obtaining the actual scattering rate of the reflected light, determining the second wear degree based on the actual scattering rate, and judging whether the first wear degree is consistent with the second wear degree. If they are consistent, the actual wear degree is determined, and the second wear degree is the first wear degree, the second wear degree or the third wear degree.

[0012] The present invention can assist in judging whether the wear degree is accurately determined based on light intensity according to the influence of the tool surface on the scattering of light source, avoid the influence of extreme external interference on light intensity and cause misjudgment, and improve the accuracy of wear degree detection.

[0013] In an optional embodiment, after determining the actual degree of wear, it also includes: if the actual degree of wear is level one or level two, generating a corresponding reminder message based on the actual wear rate; if the actual degree of wear is level three, generating a locking instruction, and controlling the detection target to be in a locked state based on the locking instruction.

[0014] By setting an adaptive detection strategy, the present invention can provide users with direct and intuitive reference information, allowing them to decide whether to replace the tool. At the same time, locking the tool when it is severely worn can force the user to replace the tool, avoiding accidents caused by severe tool wear and ensuring user safety.

[0015] In an optional embodiment, before controlling the light emitting module to emit a light source to the detection target, it also includes: obtaining a detection mode, and triggering wear detection according to the detection mode, the detection mode includes: a forced detection mode and an energy-saving detection mode; triggering wear detection according to the detection mode, including: if it is a forced detection mode, generating a detection instruction, and sending the detection instruction to the light emitting module, so that the light emitting module emits a light source to the detection target; if it is an energy-saving detection mode, obtaining the number of times the detection target is used, and comparing the number of times used with a preset number threshold, if the number of times used reaches the preset number threshold, generating a detection instruction, and sending the detection instruction to the light emitting module, so that the light emitting module emits a light source to the detection target.

[0016] The present invention provides different detection modes, which can be selected by users according to their usage needs, avoiding the inconvenience of wear detection every time use, and improving the user experience.

[0017] In a second aspect, the present invention provides a wear detection device, comprising:

[0018] a light detection module, configured to control the light emitting module to emit a light source toward a detection target, and obtain a first light intensity measured by the light receiving module after the light receiving module receives reflected light from the detection target;

[0020] The wear determination module is configured to determine a first wear degree of the detection target according to the second light intensity and a reference light intensity determined in advance in an unworn state.

[0021] In a third aspect, the present invention provides a computer device comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, computer instructions being stored in the memory, and the processor executing the wear detection method of the first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] The present invention is applicable to scenarios where the wear of household appliances such as knives is detected during use, such as a wall-breaking machine. The present invention provides a wear detection method that accurately determines the degree of tool wear by optically detecting wear.

[0034] According to an embodiment of the present invention, an embodiment of a wear detection method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0035] In this embodiment, a wear detection method is provided, which can be used in the control module of the above-mentioned household appliance. Figure 1 FIG. 1 is a flow chart of a wear detection method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0036] Step S101 : controlling the light emitting module to emit a light source toward a detection target, and obtaining a first light intensity measured by the light receiving module after the light receiving module receives reflected light from the detection target.

[0037] Specifically, in an embodiment of the present invention, taking a wall breaking machine as an example, a light emitting module and a light receiving module are pre-installed on the wall breaking machine to achieve optical detection. In order to ensure that the light source emitted by the light emitting module can be fixedly and evenly irradiated to the entire surface of the wall breaking machine tool and cover all detection areas, the light emitting module can be installed at a suitable position on the wall breaking machine, such as on the lid of the wall breaking machine, for example only, and not limited to this. When the light source is irradiated on the tool, due to the smooth surface of the tool, it can reflect the light source to form reflected light. In order to ensure that the reflected light can be accurately captured by the light receiving module, the light receiving module is set at a symmetrical position of the light emitting module, and the light receiving module can directly measure the light intensity of the reflected light, such as a photodiode, but not limited to this. In order to ensure the accuracy and safety of the detection, the embodiment of the present invention performs detection before or after the use of the wall breaking machine, that is, wear detection is performed when the tool is in a stationary state.

[0038] In some optional embodiments, when wear detection is required, the control module generates a control instruction and sends it to the light emitting module, causing it to emit a light source of a specific wavelength. The light source is then reflected from the tool surface, and the light receiving module receives the reflected light from the tool and directly measures a first light intensity I1 of the reflected light. The control module then obtains the first light intensity I1 measured by the light receiving module. In actual operation, to improve the accuracy of light intensity measurement, the light emitting module and the light receiving module can be controlled to perform multiple measurements, and the control module calculates the average of the light intensities obtained from these multiple measurements as the first light intensity I1.

[0039] Step S102 : determining a light compensation parameter according to the current detection environment, and adjusting the first light intensity based on the light compensation parameter to obtain a second light intensity.

[0040] Specifically, in an embodiment of the present invention, during the optical detection process, the detection environment has a decisive influence on the results of the optical detection. For example, changes in ambient temperature can cause the output power and wavelength of the light source (such as a semiconductor laser) to drift; stray ambient light such as natural light enters the light receiving module and is superimposed on the reflected light of the detection target; the humidity in the wall-breaking machine changes the refractive index of the air, causing a slight shift in the propagation path of the emitted light. This is only an example and is not limited to this. Therefore, the embodiment of the present invention determines the light compensation parameter K based on the current detection environment, and then adjusts the first light intensity I1 obtained by direct measurement, which can compensate for the influence of the detection environment on the propagation of light, thereby obtaining an accurate second light intensity I2.

[0041] Step S103 : determining a first wear degree of the detection target according to the second light intensity and a reference light intensity determined in advance in an unworn state.

[0042] Specifically, in an embodiment of the present invention, in order to detect the wear of the tool surface based on the second light intensity I2 of the light reflected from the tool, it is necessary to determine the reference light intensity I0 of the tool in an unworn state, and then determine the current first degree of wear by comparing the current second light intensity I2 with the reference light intensity I0 when unworn. In an embodiment of the present invention, a reference plate is pre-installed near the tool in the wall breaker, and the reference light intensity I0 of the tool in an unworn state is determined based on the reference plate of the wall breaker. The reference plate is a measuring element and can be a flat plate with stable reflection characteristics. It is necessary to ensure that the reference plate and the tool are in the same lighting environment to avoid the influence of ambient light differences on the measurement results. The material, surface treatment and installation angle of the reference plate should be as similar as possible to the unworn surface of the tool. The reference plate is embedded inside the wall breaker to enable the wall breaker to operate normally. When the light source is emitted to the tool, it is also sent to the reference plate. The light reflection conditions of the reference plate and the new tool are consistent. It is necessary to keep the distance equal and the relative position of the tool and the reference plate stable. In practice, however, to distinguish the light reflected from the tool and the reference plate, the emission time or wavelength of the light source can be used, or the angle of the reflected light can be distinguished based on the relative position of the tool and the reference plate. These are not specified here. After the tool is first installed and unworn, optical inspection of the reference plate is performed to obtain the baseline light intensity I0 of the tool in its unworn state.

[0043] In some optional embodiments, the present invention provides a multi-level wear warning system to provide intuitive user reminders. For example, the first wear level includes level 1, level 2, and level 3. After determining the different wear levels, the Bluetooth module of the wall breaker can send the judgment results to the user's mobile phone app, and the buzzer of the wall breaker can be activated to play a pre-recorded voice, or the LED indicator of the wall breaker can be illuminated according to different modes, etc., for example only and not limited to this.

[0044] The wear detection method provided by the present invention emits a light source toward a detection target, obtains a first light intensity of light reflected from the detection target, adjusts the first light intensity based on a light compensation parameter determined in the current detection environment to obtain a second light intensity, and determines a first degree of wear of the detection target based on the second light intensity and a reference light intensity in an unworn state. By utilizing optical detection principles, the present invention can detect the wear of a tool based on physical structures such as the flatness, roughness, or defects on the tool surface. This reduces human misjudgment and allows detection based on the actual characteristics of the tool, improving detection accuracy, avoiding excessive tool wear or premature replacement, saving costs for users, and ultimately improving user satisfaction and experience.

[0045] In this embodiment, a wear detection method is provided, which can be used in the control module of the above-mentioned household appliance. Figure 2FIG. 1 is a flow chart of a wear detection method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0046] Step S201: Control the light emitting module to emit light to the detection target, and after the light receiving module receives the reflected light of the detection target, obtain the first light intensity measured by the light receiving module. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0047] Step S202 : determining a light compensation parameter according to the current detection environment, and adjusting the first light intensity based on the light compensation parameter to obtain a second light intensity.

[0048] Specifically, the above step S202 includes:

[0049] Step S2021 , in the current detection environment, after emitting a light source toward a reference target and receiving reflected light from the reference target, a third light intensity of the reflected light is obtained.

[0050] Specifically, in an embodiment of the present invention, under the current detection environment, the reference plate installed in the wall-breaking machine is used as a reference target to determine the light compensation parameters, but the present invention is not limited to this. According to the above-mentioned method of emitting a light source to the detection target, the light emitting module is controlled to emit a light source of a specific wavelength to the reference plate. When the light source reaches the reference plate and forms reflected light, the light receiving module can receive the reflected light from the reference plate and directly measure the third light intensity I3 corresponding to the reflected light.

[0051] Step S2022: Calculate the ratio of the third light intensity to the reference light intensity to obtain a light compensation parameter.

[0052] Specifically, in an embodiment of the present invention, the reference light intensity I0 and the third light intensity I3 are both reflected light from the reference plate, and because the reference plate does not participate in the operation of the wall breaker, there is no wear. If the influence of the current detection environment is not taken into account, the values ​​of the reference light intensity I0 and the third light intensity I3 are basically equal, but in actual operation, there must be environmental influences. Therefore, the changes in the reference light intensity I0 and the third light intensity I3 can reflect the impact of the current detection environment on optical detection. Therefore, the ratio of the third light intensity to the reference light intensity is calculated as the light compensation parameter under the current detection environment. The calculation formula is as follows:

[0053]

[0054] Here, K is a light compensation parameter. For example, if the reference light intensity I0 is 100 and the third light intensity I3 under the current detection environment is 95, the light compensation parameter K is 95 / 100=0.95. This is for example only and is not limited thereto.

[0055] Step S2023: Calculate the product of the first light intensity and the light compensation parameter to obtain the second light intensity.

[0056] Specifically, in the embodiment of the present invention, after optical inspection of the tool under the current inspection environment, the first light intensity I1 obtained is affected by the environment, and the light compensation parameter K represents the impact of the current inspection environment on the optical inspection. Therefore, the ratio of the first light intensity I1 to the light compensation parameter K is calculated to obtain the second light intensity I2 after light compensation. The calculation formula is as follows:

[0057]

[0058] For example, the first light intensity I1 is 85, the light compensation parameter K in the current detection environment is 0.95, and the second light intensity I2 is 85 / 0.95≈89.47. This is only an example and is not limited to this.

[0059] Step S203 : determining a first wear degree of the detection target according to the second light intensity and a reference light intensity determined in advance in an unworn state.

[0060] Specifically, the above step S203 includes:

[0061] Step S2031 , calculating the actual intensity difference between the reference light intensity and the second light intensity, and calculating the ratio of the actual intensity difference to the reference light intensity to obtain an actual intensity difference ratio.

[0062] Specifically, in an embodiment of the present invention, the reference light intensity I0 obtained when the tool is in an unworn state is used as a reference. The reference light intensity I0 can represent the optical properties of the tool in an unworn state. Therefore, when detecting the wear condition during use, the actual intensity difference ΔI between the reference light intensity I0 and the second light intensity I2 is calculated, that is, ΔI = I0-I2, and the ratio of the actual intensity difference ΔI to the reference light intensity I0 is calculated to obtain the actual intensity difference ratio σ, that is, σ = ΔI / I0. The change in optical properties reflected by the actual intensity difference ratio σ is caused by tool wear.

[0063] Step S2032: determining the actual wear rate according to the actual strength difference ratio and a preset corresponding relationship between the strength difference ratio and the wear rate.

[0064] Specifically, in the embodiment of the present invention, in order to convert the change in optical properties into a degree of wear that is easily accepted by the user, the corresponding relationship between the intensity difference ratio and the wear rate is pre-set based on the reflected light attenuation rate. Taking an intensity difference ratio of 5% as an example, the corresponding relationship is as follows:

[0065] Intensity difference ratio Wear rate 1 Wear rate 2 Wear rate 3 Wear rate 4 5％ 0.8％ 1.0％ 1.2％ 1.4％

[0066] The correspondence provided in the table above is for example only and is not limited to this. Users can select different correspondences according to their personal needs. The corresponding wear degree reminder speed varies. The smaller the wear rate corresponding to the intensity difference ratio of 5%, the slower the wear degree reminder. The larger the wear rate corresponding to the intensity difference ratio of 5%, the faster the wear degree reminder. Taking the wear rate determined to be 1.0% when the intensity difference ratio is 5% as an example, the formula for calculating the actual wear rate δ is as follows:

[0067]

[0068] For example, the first light intensity I1 is 85, the light compensation parameter K under the current detection environment is 0.95, the second light intensity I2 is 85 / 0.95≈89.47, the actual intensity difference ΔI is 100-89.47=10.53, the actual intensity difference ratio σ is (10.53) / 100=10.53%, and the actual wear rate δ is 10.53% / 5%*1%≈2.1%.

[0069] Step S2033 : Compare the actual wear rate with the first preset warning threshold to determine a first wear degree, which can be a first wear degree, a second wear degree, or a third wear degree.

[0070] Specifically, in an embodiment of the present invention, multiple levels of wear warning are pre-set. For example, the first wear level includes: first wear level, second wear level, and third wear level, and thus a corresponding first preset warning threshold is set. The first preset warning thresholds set in the embodiment of the present invention include: a first wear rate threshold of 40% and a second wear rate threshold of 70%, which are examples only and are not limited to this. By comparing the calculated actual wear rate δ with the first wear rate threshold of 40% and the second wear rate threshold of 70%, if the actual wear rate δ is ≤40%, the first wear level is the first wear level; if 40% < actual wear rate δ ≤70%, the first wear level is the second wear level; if the actual wear rate δ is greater than 70%, the first wear level is the third wear level.

[0071] The wear detection method provided by the present invention emits a light source toward a detection target, obtains a first light intensity of light reflected from the detection target, adjusts the first light intensity based on a light compensation parameter determined in the current detection environment to obtain a second light intensity, and determines a first degree of wear of the detection target based on the second light intensity and a reference light intensity in an unworn state. By utilizing optical detection principles, the present invention can detect the wear of a tool based on physical structures such as the flatness, roughness, or defects on the tool surface. This reduces human misjudgment and allows detection based on the actual characteristics of the tool, improving detection accuracy, avoiding excessive tool wear or premature replacement, saving costs for users, and ultimately improving user satisfaction and experience.

[0072] In this embodiment, a wear detection method is provided, which can be used in the control module of the above-mentioned household appliance. Figure 3 FIG. 1 is a flow chart of a wear detection method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0073] Step S301 : acquiring a detection mode and triggering wear detection according to the detection mode. The detection modes include: a mandatory detection mode and an energy-saving detection mode.

[0074] Specifically, in an embodiment of the present invention, to meet the diverse individual needs of users, a mandatory detection mode and an energy-saving detection mode are pre-set for the wall breaker, allowing users to select either detection mode based on their needs. The mandatory detection mode performs a wear check before and after each use, while the energy-saving detection mode performs a wear check only after a certain number of uses. Selecting the energy-saving detection mode avoids the inconvenience of performing a wear check every time the wall breaker is used, thereby improving the user experience. When the wall breaker is first used, the mandatory detection mode is set by default. Users can choose whether to switch to the energy-saving detection mode based on their needs or the machine's usage. For example, in the early stages of the wall breaker's use, when blade wear is not noticeable, the user can switch to the energy-saving detection mode. Later in the machine's use, when blade wear is more noticeable, the user can switch back to the mandatory detection mode. Furthermore, users can also turn the detection mode off or on based on their needs. For example, in the early stages of the wall breaker's use, when the blade is not worn, the detection mode can be turned off, and wear checks can be omitted after each use. After a period of use, the detection mode can be turned on, allowing the user to select either the energy-saving detection mode or the mandatory detection mode.

[0075] In some optional implementations, the above step S301 includes:

[0076] Step S3011: If it is a forced detection mode, a detection instruction is generated and sent to the light emitting module, so that the light emitting module emits light to the detection target.

[0077] Specifically, in an embodiment of the present invention, if the user selects mandatory detection mode, before or after each use of the wall breaker, the control module of the wall breaker automatically generates a detection instruction and sends the detection instruction to the light emitting module, which transmits a light source to the cutter, thereby triggering wear detection. Under this setting, if the user uses the wall breaker frequently, the mandatory detection mode can be selected to conduct timely wear detection on the cutter, avoiding the reduction of the use effect caused by cutter wear.

[0078] In step S3012, if it is an energy-saving detection mode, the number of times the detection target is used is obtained, and the number of times used is compared with the preset number threshold. If the number of times used reaches the preset number threshold, a detection instruction is generated and sent to the light emitting module to enable the light emitting module to emit a light source to the detection target.

[0079] Specifically, in an embodiment of the present invention, if the user does not use the wall breaker frequently, the energy-saving detection mode can be selected. In the energy-saving detection mode, the user can set a preset number of thresholds, for example 10 times, that is, a wear detection is performed after each 10 uses of the wall breaker. Under this setting, a counter is provided in the wall breaker to accumulate the number of times the wall breaker is used. Before the wear detection, the control module obtains the accumulated number of uses and compares the number of uses with the preset number threshold. If the number of uses reaches the preset number threshold, a detection instruction is generated and sent to the light emitting module, which transmits a light source to the tool, thereby triggering the wear detection. If the number of uses does not reach the preset number threshold, the wear detection is not triggered.

[0080] Step S302: Control the light emitting module to emit light to the detection target, and after the light receiving module receives the reflected light of the detection target, obtain the first light intensity measured by the light receiving module. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0081] Step S303: Determine the light compensation parameter according to the current detection environment, and adjust the first light intensity based on the light compensation parameter to obtain the second light intensity. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0082] Step S304: Determine the first wear degree of the detection target based on the second light intensity and a reference light intensity previously determined in an unworn state. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0083] Step S305 , obtaining the actual scattering rate of the reflected light, determining the second wear degree according to the actual scattering rate, and judging whether the first wear degree is consistent with the second wear degree, and if they are consistent, determining the actual wear degree.

[0084] Specifically, in an embodiment of the present invention, in order to avoid errors in optical detection based on light intensity caused by extreme environments, which leads to inaccurate wear detection results, a light scattering measuring device is set in the wall breaking machine, and the scattering distribution characteristics of the reflected light are used for auxiliary judgment. When the light emitting module transmits the light source to the tool, and the light source passes through the tool to form reflected light, the light scattering measuring device directly measures the scattering rate of the reflected light, and the control module obtains the actual scattering rate of the reflected light, and compares the actual scattering rate with the second preset warning threshold to determine the second degree of wear. Among them, why the optical detection results based on light intensity remain consistent, the second preset warning threshold includes: a first scattering rate threshold and a second scattering rate threshold, and the corresponding second degree of wear includes: a first degree of wear, a second degree of wear and a third degree of wear. By comparing the actual scattering rate with the first scattering rate threshold and the second scattering rate threshold, the second degree of wear is determined to be a first degree of wear, a second degree of wear or a third degree of wear.

[0085] In some optional implementations, the present invention compares the wear detection results based on light intensity with the wear detection results based on light scattering to determine whether the resulting wear degrees are consistent. If they are consistent, the final actual wear degree is determined. If they are inconsistent, the wear detection is repeated. If the detection results are still inconsistent after multiple tests, a reminder message is generated for user confirmation.

[0086] Step S306: If the actual wear degree is level one or level two, a corresponding reminder message is generated according to the actual wear rate; if the actual wear degree is level three, a locking instruction is generated, and the detection target is controlled to be in a locked state based on the locking instruction.

[0087] Specifically, in an embodiment of the present invention, after determining that the actual wear degree is the first level wear degree or the second level wear degree, the tool can be used normally at this time, so the corresponding reminder information is generated according to the actual wear rate δ, including voice reminder information, light reminder information and text reminder information. For voice reminder information, the pre-recorded voice reminder information can also be directly called according to the actual wear rate δ, and then the obtained voice reminder information is sent to the buzzer, and the buzzer issues a voice reminder, such as "Current wear is 23%, the status is normal", "Current wear is 43%, please replace the tool in time", etc. For light reminder information, it is sent to the LED indicator light, and the LED indicator light issues a light reminder. For text reminder information, the text reminder information is sent to the user's mobile phone APP through the Bluetooth module of the wall breaker.

[0088] In some optional embodiments, if the actual wear degree is determined to be level three, the tool cannot meet the usage requirements. In order to ensure the use effect or safety, in addition to the voice prompt, the control module generates a locking instruction and cuts off the motor drive circuit through the relay based on the locking instruction, forcing the blender to enter a locked state until the tool is replaced.

[0089] The wear detection method provided by the present invention emits a light source toward a detection target, obtains a first light intensity of light reflected from the detection target, adjusts the first light intensity based on a light compensation parameter determined in the current detection environment to obtain a second light intensity, and determines a first degree of wear of the detection target based on the second light intensity and a reference light intensity in an unworn state. By utilizing optical detection principles, the present invention can detect the wear of a tool based on physical structures such as the flatness, roughness, or defects on the tool surface. This reduces human misjudgment and allows detection based on the actual characteristics of the tool, improving detection accuracy, avoiding excessive tool wear or premature replacement, saving costs for users, and ultimately improving user satisfaction and experience.
