[0002] For example, many existing food processing equipment, such as microwave ovens and ovens, can set operating parameters such as processing power (e.g., heating power) and processing time (e.g., heating time) based on the weight of the object being processed during defrosting or baking. In these situations, high weight detection accuracy is required. However, the weight detection devices installed in existing processing equipment mostly rely on mechanical weight sensors or resistance strain gauges. These existing weight detection devices suffer from low detection accuracy, inability to quickly respond to weight changes, complex installation structures, and high maintenance costs.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0059] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0060] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0061] See also Figure 1-2 The first part of the embodiment of the present application provides a weight detection device 100, which includes a load-bearing portion 110, a mounting portion 130, an elastic member 120, a magnetic element 140, and a linear Hall element 150. The load-bearing portion 110 is used to carry an object 400a whose weight needs to be detected, and the mounting portion 130 is used to install the weight detection device 100 at a location where it is needed. For example, the weight detection device 100 can be installed on the processing equipment 1 described below through the mounting portion 130. The mounting portion 130 is spaced apart from the load-bearing portion 110; the elastic member 120 is disposed between the load-bearing portion 110 and the mounting portion 130, and the opposite ends of the elastic member 120 are respectively in contact with the load-bearing portion 110 and the mounting portion 130, so that when the load-bearing portion 110 carries the object 400a, the elastic member 120 can be elastically compressed and deformed by the weight of the object 400a, thereby changing the position of the load-bearing portion 110 relative to the mounting portion 130. A plurality of magnetic elements 140 are provided, and the plurality of magnetic elements 140 are disposed on the carrier portion 110 and spaced apart from each other. A plurality of linear Hall elements 150 are also provided, and the plurality of linear Hall elements 150 are disposed on the mounting portion 130 and spaced apart from each other. Each linear Hall element 150 is individually located within the magnetic field of a magnetic element 140 to detect a corresponding Hall signal.

[0062] It should be noted that the embodiments of the present application do not limit the specific shapes of the carrying portion 110 and the mounting portion 130, as long as they can satisfy the above relative position relationship. Figure 2 As shown, the bearing portion 110 can be set to a disc shape so that the bearing portion 110 can carry an object 400a that needs to be detected in weight and make it convenient to arrange multiple magnetic elements 140. The mounting portion 130 can also be set to a disc shape so that the mounting portion can facilitate the arrangement of multiple linear Hall elements 150. The elastic member 120 of the embodiment of the present application refers to an object that can undergo elastic compression deformation when subjected to a compressive force, such as various springs, rubber parts and thermoplastic elastomers (TPE / TPU). The magnetic element 140 refers to a magnetic material that can generate a magnetic field and can detect the corresponding Hall signal by a linear Hall element, such as various types of magnetic beads, magnetic blocks, magnetic sheets or electromagnets. The linear Hall element 150 refers to a semiconductor component that can detect a Hall signal (such as a Hall voltage) through the Hall effect, and the Hall signal it detects is in direct proportional linear relationship with the magnetic induction intensity of its own position in the magnetic field of the magnetic element 140. For example, the linear Hall element 150 can be a commonly used linear Hall chip of various specifications.

[0063] It can be understood that when the carrying portion 110 does not carry the object 400a, the linear Hall element 150 provided on the mounting portion 130 is in a first position relative to the magnetic element 140 provided on the carrying portion 110. At this time, in the magnetic field of the magnetic element 140, the magnetic induction intensity at the position where the linear Hall element 150 is located is B1; when the carrying portion 110 carries an object 400a whose weight needs to be detected, the elastic member 120 will be compressed and deformed due to the influence of the gravity of the object 400a, thereby causing the carrying portion 110 to approach the mounting portion 130, so that the linear Hall element 150 provided on the mounting portion 130 is in a second position relative to the magnetic element 140 provided on the carrying portion 110. At this time, in the magnetic field of the magnetic element 140, the magnetic induction intensity at the position where the linear Hall element 150 is located is B2. Because the Hall signal detected by the linear Hall element 150 is in direct proportional linear relationship with the magnetic induction intensity at its position, the Hall signal detected by the linear Hall element 150 when the load-bearing portion 110 carries an object (as well as the Hall signal detected when the load-bearing portion does not carry an object) can be used to calculate the change in magnetic induction intensity, and then the position change of the linear Hall element 150 relative to the magnetic element 140 can be calculated based on the change in magnetic induction intensity. This position change is also the elastic compression deformation of the elastic member 120, and the pressure on the elastic member 120 can be solved based on this elastic compression deformation. The pressure on the elastic member 120 is determined by the weight of the object 400a, so the weight of the object 400a carried on the load-bearing portion 110 can be finally calculated, so that the weight detection device 100 of the embodiment of the present application can achieve the purpose of accurately detecting the weight of the object.

[0064] In some other embodiments, multiple magnetic elements 140 can be set on the mounting portion 130, and multiple linear Hall elements 150 can be set on the supporting portion 110, and each linear Hall element 150 can also be located separately in the magnetic field of a magnetic element 140 so that each linear Hall element 150 can cooperate with a magnetic element 140 separately to detect the corresponding Hall signal.

[0065] The weight detection device 100 of the embodiment of the present application, on the one hand, is configured by spacing the mounting portion 130 and the carrying portion 110, and configuring the two opposite ends of the elastic member 120 to abut against the carrying portion 110 and the mounting portion 130, so that the magnetic element 140 and the linear Hall element 150 are respectively arranged on one of the carrying portion 110 and the mounting portion 130 and the other thereof. When the carrying portion 110 carries an object 400a whose weight needs to be detected, the elastic element 120 is elastically deformed due to the influence of the weight of the object 400a, thereby changing the position of the linear Hall element 150 relative to the magnetic element 140, so as to calculate the weight of the object through the Hall signal detected by the linear Hall element 150; because the detection accuracy of the Hall signal itself is low, the weight detection device 100 can be realized by adjusting the relative position of the linear Hall element 150. The accuracy is higher than that of other mechanical weight sensors or resistance strain gauges, and the elastic element 120 is provided to amplify the position change of the linear Hall element 150 relative to the magnetic element 140 caused by the weight of the object 400a, so the weight detection device 100 has high accuracy in detecting the weight of the object; on the other hand, when the weight detection device 100 needs to be installed on any type of processing equipment, it is only necessary to install the mounting portion 150 on the processing equipment and enable the bearing portion 110 to carry the object whose weight needs to be detected along the direction of gravity. The process of installing and disassembling the weight detection device 100 on the processing equipment is simple, which facilitates the application of this high-precision weight detection device 100 to different types of processing equipment. It can be seen that by using the weight detection device 100 of the embodiment of the present application, the technical problem that the existing processing equipment is not convenient for disassembling and assembling high-precision weight detection devices can be solved.

[0066] In addition, the weight detection device 100 of the embodiment of the present application, by providing a plurality of linear Hall elements 150 and magnetic elements 140 that cooperate with each other, can also enable the plurality of linear Hall elements 150 to detect corresponding Hall signals so as to obtain a plurality of Hall signals; because the plurality of Hall signals are directly related to the pressure applied to the carrying portion 110 by the object 400a carried on the carrying portion 110 due to its own gravity, the plurality of Hall signals obtained can be used to determine whether the direction of the pressure applied to the carrying portion 110 by the object 400a carried on the carrying portion 110 meets the preset requirements, thereby determining whether the placement position of the object 400a carried on the carrying portion 110 is correct, thereby realizing position detection of the object 400a carried on the carrying portion 110.

[0067] See also Figure 1 In one embodiment, the central axis of the carrying portion 110 coincides with the central axis of the mounting portion 130, that is, the central axis of the carrying portion 110 and the central axis of the mounting portion 130 are substantially aligned. The plurality of magnetic elements 140 are evenly spaced about the central axis of the carrying portion 110, and the plurality of linear Hall elements 150 are evenly spaced about the central axis of the mounting portion 130. It should be noted that the central axis herein refers to a straight line perpendicular to the upper surface of the carrying portion 110 (or mounting portion 130) and passing through the geometric center of the upper surface of the carrying portion 110 (or mounting portion 130).

[0068] It can be understood that in this embodiment, since the multiple magnetic elements 140 are evenly spaced around the central axis of the load-bearing portion 110, and the multiple linear Hall elements 150 are evenly spaced around the central axis of the mounting portion 130, if the weight of the object carried on the load-bearing portion 110 is also evenly distributed around the central axis of the load-bearing portion 110, the magnitudes of the multiple Hall signals detected by the multiple linear Hall elements 150 should be equal. This characteristic can be used to more simply and effectively determine whether the placement position of the object carried on the load-bearing portion 110 is correct based on the multiple Hall signals obtained, thereby greatly simplifying the calculation steps in the judgment process, thereby facilitating calculations and saving computing resources. In addition, by evenly spacing the magnetic elements 140 and the linear Hall elements 150 around the central axis, the blind spots of object weight detection can be reduced, thereby facilitating more accurate detection of the weight of the object carried on the load-bearing portion 110 and improving the accuracy of object position detection.

[0069] See also Figure 3-4 The second part of the embodiment of the present application provides a processing equipment 1, which includes a cabinet 200 and the weight detection device 100 of the above embodiment. The cabinet 200 is provided with an installation position, and the installation part 130 of the weight detection device 100 is installed at the installation position. The processing equipment 1 is used to process the object to be processed 400b, and the supporting part 110 is used to support the object to be processed 400b.

[0070] It should be noted that the processing equipment 1 of the embodiment of the present application can be various food processing equipment that are currently available or will be developed in the future, such as microwave ovens, ovens, steam ovens, smokers, quick freezers, electric fryers, fermentation boxes and food dryers, or processing equipment in other industries, such as industrial dehumidification drying cabinets, battery aging test cabinets and constant temperature and humidity test chambers, etc., as long as it has a cabinet body 200 and can process the object 400b to be processed with a certain weight placed on the load-bearing part 110 in the cabinet body 200.

[0071] It can be understood that the processing equipment 1 of this embodiment can install the weight detection device 100 through the installation position set on the cabinet 200, and the bearing portion 110 of the weight detection device 100 can carry the object to be processed 400b, so that the processing equipment 1 can process the object to be processed 400b while performing high-precision weight detection of the object to be processed 400b through the weight detection device 100. And because the processing equipment 1 is installed with the weight detection device 100 provided by the embodiment of the present application, during installation, it is only necessary to install the mounting portion 130 of the weight detection device 100 on the mounting position on the cabinet 200, and enable the bearing portion 110 to carry the object whose weight needs to be detected along the direction of gravity. When disassembling the weight detection device 100, it is only necessary to separate the mounting portion 130 from the mounting position. This makes the process of installing and disassembling the weight detection device 100 on the processing equipment simple and easy to operate, solving the technical problem that the existing processing equipment is not convenient for disassembling high-precision weight detection devices.

[0072] In one embodiment, the mounting portion 130 of the weight detection device 100 is installed at the mounting position by a detachable connection method such as a threaded connection, a snap connection, or a magnetic connection, thereby simplifying the process of installing and disassembling the weight detection device 100.

[0073] See also Figure 4 In one embodiment, the mounting position 200b is provided on the inner wall of the cabinet 200. By providing the mounting position 200b on the inner wall of the cabinet 200, it is possible to facilitate the mounting portion 130 of the weight detection device 100 to be directly mounted on the inner wall of the cabinet 200 by being mounted on the mounting position 200b. Moreover, since the mounting position 200b is located on the inner side of the cabinet 200, it is possible to minimize the impact of the external environment on the mounting connection structure between the mounting portion 130 and the mounting position 200b, as well as the impact of the external environment on the object to be processed 400b, thereby ensuring the weight detection accuracy of the object to be processed 400b. For example, the mounting portion 130 can be mounted on the mounting position 200b on the inner wall of the cabinet 200 by a fixed connection method such as welding, bonding, snap connection, and bolt connection.

[0074] See also Figure 3 In one embodiment, the processing equipment 1 is a microwave oven, and the mounting position is a mounting groove 200a set at the bottom of the cabinet 200. The processing equipment 1 also includes a storage member 300, which includes a storage tray 310 and a support shaft 320 fixed to the bottom of the storage tray 310. The support shaft 320 passes through the notch of the mounting groove 200a and is fixed on the supporting portion 110 to be supported by the supporting portion 110. The storage tray 310 is used to place the object 400b to be processed.

[0075] It can be understood that in this embodiment, by setting the installation position as the installation groove 200a at the bottom of the cabinet 200, the installation part 130 can be easily and stably installed at the installation position. By setting the storage part 300 including the storage tray 310 and the support shaft 320, the object to be processed 400b can be more securely placed on the storage tray 310 and supported by the support part 110; by allowing the support shaft 320 to pass through the notch of the installation groove 200a and be fixed on the support part 110, the weight detection device 100 can be more stably connected to the storage part 300, so as to achieve the purpose of carrying the object to be processed 400b and performing high-precision weight detection on it.

[0076] See also Figure 5 Based on the processing equipment 1 provided in the above embodiment of the present application, the third part of the embodiment of the present application further provides a control method for the processing equipment, the control method comprising:

[0077] S100, acquiring a plurality of Hall signals detected by a plurality of the linear Hall elements;

[0078] S200: Generate a work instruction based on the plurality of Hall signals, so as to instruct a processing device to perform work through the work instruction.

[0079] Among them, the "generating a work instruction based on the multiple Hall signals" in step S200 refers to calculating the weight of the object to be processed 400b carried by the carrying portion 110 of the weight detection device 100 or related information directly related to the weight of the object to be processed 400b (such as the gravity of the object to be processed 400b) based on the multiple Hall signals, and then generating a work instruction based on the weight of the object to be processed 400b or related information directly related thereto. The work instruction here refers to instruction information that can control the processing equipment 1 to perform various operations (such as adjusting the processing power, sending prompt information, etc.), including the first work instruction, the second work instruction, and the third work instruction described below.

[0080] It can be understood that in this embodiment, by executing steps S100 and S200, the weight of the object to be processed 400b or related information directly related to it in the processing equipment 1 can be accurately detected, and a work instruction can be generated according to the weight of the object to be processed 400b or related information, so that the work instruction matches the weight of the object to be processed 400b, so that the specific way in which the processing equipment 1 processes the object to be processed 400b according to the instructions of the work instruction matches the weight of the object to be processed 400b, so that the processing equipment 1 can better complete the processing of the object to be processed 400b.

[0081] It should be noted that the control method of the processing equipment of the embodiment of the present application can be implemented based on a controller, and the controller is in communication with the linear Hall element 150 of the weight detection device 100 so as to obtain the Hall signal. The controller can be directly installed on the cabinet 200 of the processing equipment 1, or it can be installed on the weight detection device 100, or it can be set separately relative to the processing equipment 1. For example, the controller of the embodiment of the present application can be, but is not limited to: a computer terminal (Personal Computer, PC); an industrial control computer terminal (Industrial Personal Computer, IPC); a mobile terminal; a server; a system including a terminal and a server, and implemented through the interaction between the terminal and the server; a programmable logic controller (Programmable Logic Controller, PLC); a field programmable gate array (Field-Programmable Gate Array, FPGA); a digital signal processor (Digital Signal Processor, DSP) or a microcontroller unit (Microcontroller unit, controller), etc.

[0082] See also Figure 6 In one embodiment, step S200 specifically includes the following steps:

[0083] S210, determining whether the position of the object to be processed relative to the supporting portion is correct based on the multiple Hall signals;

[0084] S220. Generate a first work instruction according to the judgment result, so as to instruct the processing equipment to work through the first work instruction.

[0085] Step S210 involves determining, based on multiple Hall signals, whether the direction of pressure applied by the object 400b to be processed on the carrying portion 110 meets preset requirements, thereby determining whether the object 400b to be processed on the carrying portion 110 is correctly positioned relative to the carrying portion 110. Step S210 may yield two possible determination results: correct position or incorrect position. Step S220 involves generating a matching first operating instruction based on the determination result obtained in step S210, thereby instructing the processing device 1 to perform an operation via the first operating instruction. Taking the processing equipment as a microwave oven as an example, when executing step S210 to obtain a judgment result that the position is correct, step S220 generates a first working instruction to start a preset thawing program based on the judgment result, so that the processing equipment can thaw the object to be processed (i.e., food that needs to be thawed) that is placed in the correct position according to the instruction of the first working instruction; and when executing step S210 to obtain a judgment result that the position is incorrect, step S220 generates a prompt message (such as displaying text information on the display screen or playing voice information through the speaker) based on the judgment result to prompt the user that the placement position of the object to be processed is incorrect, so that the user can adjust the placement position of the object to be processed to ensure that the processing equipment only processes the object to be processed that is placed in the correct position.

[0086] It can be understood that in this embodiment, by executing steps S210 and S220, the processing equipment 1 can determine whether the placement position of the object to be processed 400b is correct through the multiple Hall signals obtained by the weight detection device 100 and then generate a corresponding first work instruction, thereby ensuring that when the processing equipment 1 processes the object to be processed 400b, the position of the object to be processed 400b relative to the supporting part 110 is correct and appropriate, so that the processing equipment 1 only processes the object to be processed 400b that is placed in the correct position, so as to ensure the processing effect of the processing equipment 1 on the object to be processed 400b.

[0087] See also Figure 7 In one embodiment, step S210 specifically includes the following steps:

[0088] S211, extracting a maximum value and a minimum value of the Hall signal from the plurality of Hall signals;

[0089] S212, calculating a measured signal difference according to the maximum value and the minimum value of the Hall signal;

[0090] S213 , comparing the measured signal difference with the preset signal difference, and judging whether the position of the object to be processed relative to the supporting part is correct based on the comparison result.

[0091] As can be understood, in this embodiment, by extracting the maximum and minimum Hall signal values ​​in step S211, a measured signal difference can be calculated in step S212. Then, by comparing the measured signal difference with a preset signal difference in step S213, it can be determined whether the measured signal difference exceeds the preset signal difference. When the measured signal difference does not exceed the preset signal difference, it indicates that the magnitude distribution of the multiple Hall signals is relatively uniform, indicating that the object 400b to be processed is likely not offset relative to the support portion 110, and thus the position of the object 400b to be processed relative to the support portion 110 can be determined to be correct. When the measured signal difference exceeds the preset signal difference, it indicates that the magnitude distribution of the multiple Hall signals is uneven, indicating that the object 400b to be processed is likely offset relative to the support portion 110, and thus the position of the object 400b to be processed relative to the support portion 110 can be determined to be incorrect. Using this method to determine whether the position of the object 400b to be processed relative to the support portion 110 is correct simplifies the calculation process, greatly improves calculation efficiency, and significantly saves computing resources.

[0092] See also Figure 8 In another embodiment, step S210 specifically includes the following steps:

[0093] S211, calculating the measured pressure applied by the object to be processed on the carrying part based on the multiple Hall signals;

[0094] S212: Compare the measured pressure with the preset pressure, and determine whether the position of the object to be processed relative to the supporting portion is correct based on the comparison result.

[0095] The preset pressure refers to the pressure applied to the support portion 110 when the object 400b to be processed is correctly positioned relative to the support portion 110. Step S212 can either directly compare the directions of the measured pressure and the preset pressure, thereby determining that the position of the object 400b to be processed relative to the support portion 110 is correct if the directions are the same or approximately the same, or that the position of the object 400b to be processed relative to the support portion 110 is incorrect if the directions are not approximately the same. Alternatively, the measured pressure and the preset pressure can be compared in magnitude. Because the calculated measured pressure values ​​will vary depending on the position of the object 400b to be processed relative to the support portion 110, the comparison of the measured pressure values ​​with the preset pressure values ​​can roughly determine whether the position of the object 400b to be processed relative to the support portion 110 is correct. For example, if the deviation between the measured pressure value and the preset pressure value is less than or equal to the preset deviation value, the position of the object 400b to be processed relative to the support portion 110 is determined to be correct. If the deviation is greater than the preset deviation value, the position of the object 400b to be processed relative to the support portion 110 is determined to be incorrect.

[0096] It will be appreciated that in this embodiment, by executing step S211, the measured pressure can be directly calculated based on the multiple Hall signals, and then by executing step S212, the measured pressure can be compared with the preset pressure, and the comparison result can be used to determine whether the position of the object to be processed 400b relative to the carrier 110 is correct. Because the measured pressure is directly calculated, and the preset pressure refers to the pressure applied to the carrier 110 when the object to be processed 400b is correctly placed, it is possible to relatively accurately determine whether the position of the object to be processed 400b relative to the carrier 110 is correct based on the comparison result of the measured pressure and the preset pressure.

[0097] See also Figure 9 In one embodiment, step S200 specifically includes the following steps:

[0098] S210, calculating and obtaining the current detected weight of the object to be processed according to the plurality of Hall signals;

[0099] S220: Generate a second work instruction according to the current detected weight, and instruct the processing equipment to work through the second work instruction.

[0100] It can be understood that in this embodiment, by executing step S210, the current detection weight of the object to be processed 400b can be accurately calculated directly based on multiple Hall signals, and by executing step S220, a second working instruction can be generated based on the current detection weight. Since the second working instruction is directly generated based on the current detection weight of the object to be processed 400b, when the processing equipment 1 is instructed to work by the second working instruction, the specific processing method of the processing equipment 1 can accurately match the weight of the object to be processed 400b, so as to facilitate the processing equipment 1 to better complete the processing of the object to be processed 400b.

[0101] For better understanding, the following two exemplary embodiments are used for illustration.

[0102] For example, in one embodiment, the processing equipment is a microwave oven, and the object to be processed is an item to be thawed. By executing step S210 to calculate the current detected weight W, a preset algorithm can be used to calculate the heating time T and heating power P based on the current detected weight W when executing step S220. Then, a second working instruction is generated based on the heating time T and heating power P, so that the microwave oven can heat the item to be thawed according to the heating time T and heating power P. This ensures that the heating process of the microwave oven accurately matches the weight of the item to be thawed, and the problem of insufficient thawing or excessive thawing will not occur. The preset algorithm used here can be specifically represented by the calculation formulas T = a·W+b, P = c·W+d, where a, b, c, and d are constants measured in multiple experiments.

[0103] For example, in another embodiment, the processing equipment is a microwave oven, and the object to be processed is the object actually carried by the carrying portion of the weight detection device at the current moment, for example, it can be an item to be thawed or food crumbs left over from the previous thawing process. The current detection weight W is calculated by executing step S210, and when executing step S220, the current detection weight W is compared with the preset minimum weight Wmin. If W≧W min , then a second working instruction for starting the thawing program is generated according to the comparison result; if W﹤Wmin, then a second working instruction for sending a prompt message is generated according to the comparison result, and the prompt message here includes information such as "No valid food is detected, please re-place" to remind the user to place the items to be thawed.

[0104] See also Figure 10 In one embodiment, step S100 specifically includes the following steps:

[0105] S110, setting multiple detection times;

[0106] S120, acquiring a plurality of Hall signals detected by the plurality of linear Hall elements at a plurality of detection moments respectively;

[0107] Step S200 specifically includes the following steps:

[0108] S210, calculating the weight change information of the object to be processed based on the multiple Hall signals obtained at multiple detection moments;

[0109] S220: Generate a third work instruction according to the weight change information, and instruct the processing equipment to perform work through the third work instruction.

[0110] Among them, the weight change information in the above steps refers to the weight change value or weight change rate, and "multiple detection moments" refers to two or more detection moments, so that the weight change information can be calculated after executing steps S110, S120 and S210.

[0111] It can be understood that in this embodiment, weight change information is obtained by calculating the Hall signals detected at multiple detection moments, and then a third working instruction is generated based on the weight change information, so as to instruct the processing equipment 1 to work through the third working instruction. The specific process of processing the object 400b to be processed by the processing equipment 1 can be dynamically adjusted to accurately match the weight change process of the object 400b to be processed, so as to facilitate the processing equipment 1 to better complete the processing of the object 400b to be processed.

[0112] For better understanding, the following two exemplary embodiments are used for illustration.

[0113] For example, in one embodiment, the processing equipment is a microwave oven, and the object to be processed is an item to be thawed. By executing step S110, at least three detection moments are set, for example, t1, t2, and t3 are set; by executing step S120, a plurality of Hall signals detected by a plurality of linear Hall elements are acquired at the three detection moments t1, t2, and t3 respectively; by executing step S210, a weight value W1 is calculated based on the plurality of Hall signals detected at the detection moment t1, a weight value W2 is calculated based on the plurality of Hall signals detected at the detection moment t2, and a weight value W3 is calculated based on the plurality of Hall signals detected at the detection moment t3, and then a first weight change rate W′ in the time period from t1 to t2 is calculated based on W1 and W2, and a weight change rate W′ is calculated based on W2 and W3. A second weight change rate W″ in the time period from t2 to t3 is obtained, and the first weight change rate W′ and the second weight change rate W″ are weight change information; by executing step S220, a third working instruction for adjusting the heating power of the microwave oven is generated according to the first weight change rate W′ and the second weight change rate W″, so as to instruct the microwave oven to adjust the heating power through the third working instruction, so that the microwave oven can better complete the thawing task. Specifically, if the first weight change rate W′ and the second weight change rate W″ are both greater than the preset weight change rate, a third working instruction for lowering the heating power of the microwave oven is generated accordingly; if the first weight change rate W′ and the second weight change rate W″ are both less than the preset weight change rate, a third working instruction for increasing the heating power of the microwave oven is generated accordingly.

[0114] For example, in another embodiment, the processing equipment is a microwave oven, and the object to be processed is a thawed item that has actually been thawed by the microwave oven. By executing step S110, two detection times t1 and t2 are set, wherein t1 is the first moment when thawing is just completed, and t2 is the second moment after a preset waiting time after thawing is completed; by executing step S120, a plurality of Hall signals detected by a plurality of linear Hall elements are obtained at the two detection times t1 and t2; by executing step S210, a weight value W1 is calculated based on the plurality of Hall signals detected at the detection time t1 and a weight value W1 is calculated based on the plurality of Hall signals detected at the detection time t2. The weight value W2 is calculated based on the multiple Hall signals detected at the moment, and the weight change value ΔW (ΔW is the weight change information, ΔW=W1-W2) is calculated based on W1 and W2. If the value of ΔW is equal to zero within the preset error range, a third working instruction is generated to instruct the microwave oven to turn off, so that the microwave oven is turned off by the third working instruction after thawing is completed; if the value of ΔW is not equal to zero within the preset error range, a third working instruction is generated to instruct the microwave oven to send a prompt message, where the prompt message includes information to remind the user to take away the thawed food, so that the microwave oven can spontaneously remind the user to take away the thawed food.
