Description

Technical Field

[0001] This application relates to the field of permanent magnet coupler technology, specifically to a permanent magnet coupler lifecycle management system, a permanent magnet coupler lifecycle management method, and a master controller. Background Technology

[0002] Damage to existing permanent magnet couplers generally falls into two categories: first, the movement of the host equipment causes the air gap (the gap between the conductor disk and the magnet disk) of the coupler to disappear, resulting in rubbing between the conductor disk and the magnet disk; second, after the equipment is overloaded, the slip between the conductor disk and the magnet disk increases, causing the conductor disk to be damaged due to a rapid increase in temperature caused by eddy currents. Currently, there are no good early warning methods for either of these damage causes, nor are there any relevant handling measures after detecting a specific cause (such as whether the damage is caused by the disappearance of the air gap or the increase in slip). As a result, users do not know how to deal with the problem when it occurs, and may only know to shut down the equipment at most. Summary of the Invention

[0003] The purpose of this invention is to provide a permanent magnet coupler lifecycle management system to at least solve one of the above-mentioned technical problems.

[0004] One aspect of the present invention provides a permanent magnet coupler lifecycle management system, the permanent magnet coupler lifecycle management system comprising: A wireless temperature sensor is mounted on a conductor disk and / or a magnetic disk to detect the temperature of the conductor disk and / or the magnetic disk. A distance sensor is installed on the conductor disk and / or the magnet disk to detect changes in the relative distance between the conductor disk and the magnet disk; Rotational speed sensors are installed on the conductor disk and the magnet disk respectively, and are used to obtain the rotational speed of the conductor disk and the rotational speed of the magnet disk. The main controller is connected to the wireless temperature sensor, distance sensor, and speed sensor respectively. It is used to acquire the information transmitted by the wireless temperature sensor, distance sensor, and speed sensor and to obtain the current state of the permanent magnet coupler based on the information transmitted by the wireless temperature sensor, distance sensor, and speed sensor.

[0005] This application also provides a method for managing the lifecycle of a permanent magnet coupler, which includes: The temperature change curve within a first preset time period is obtained using a wireless temperature sensor. The relative distance between the conductor disk and the magnet disk within a first preset time period is obtained using a distance sensor; The rotational speed of the conductor disk and the rotational speed of the magnet disk are obtained by a speed sensor, and the speed slip is obtained by the rotational speed of the conductor disk and the rotational speed of the magnet disk, thereby obtaining the speed slip change curve within a first preset time period. Obtain a preset database, which includes at least one preset triplet and a permanent magnet coupler working status analysis description for each preset triplet. Each preset triplet includes a preset temperature change curve, a preset relative distance change curve, and a preset speed slip change curve. Based on the temperature change curve, the relative distance change curve between the conductor disk and the magnet disk, and the speed slip change curve within the first preset time period, the permanent magnet coupler working status analysis description corresponding to one of the preset triplets in the preset database is obtained as the final permanent magnet coupler working status analysis description. The current state of the permanent magnet coupler is obtained based on the final permanent magnet coupler operating state analysis description.

[0006] Optionally, based on the temperature change curve, the relative distance change curve between the conductor disk and the magnet disk, and the speed slip change curve within the first preset time period, the permanent magnet coupler operating status analysis description corresponding to one of the preset triplet groups in the preset database is obtained, including: The similarity between the temperature change curve within the first preset time period and each preset temperature change curve is obtained, and this similarity is called temperature similarity. The similarity between the curve of relative distance change within the first preset time period and the preset curve of relative distance change is obtained. This similarity is called distance similarity. The similarity between the speed slip change curve within the first preset time period and each preset speed slip change curve is obtained, and this similarity is called speed slip similarity. Based on the similarity of various temperatures, distances, and speed slip, the working state analysis description of the permanent magnet coupler corresponding to one of the three pairs in the preset database is obtained.

[0007] Optionally, the permanent magnet coupler operating status analysis description corresponding to one of the preset triplets in the preset database is obtained based on various temperature similarities, various distance similarities, and various rotational speed slip similarities. This includes: The number of temperature similarities exceeding a first temperature similarity threshold, the number of distance similarities exceeding a first distance similarity threshold, and the number of speed slip similarities exceeding a first speed slip similarity threshold are obtained. When there is one and only one temperature similarity exceeding the first temperature similarity threshold, one and only one distance similarity exceeding the first distance similarity threshold, and one and only one speed slip similarity exceeding the first speed slip similarity threshold, it is determined whether the preset temperature change curve corresponding to the temperature similarity exceeding the first temperature similarity threshold, the preset change curve of relative distance change corresponding to the distance similarity exceeding the first distance similarity threshold, and the preset speed slip change curve corresponding to the speed slip similarity exceeding the first speed slip similarity threshold are in the same triplet. If so, then... Obtain the operating status analysis description of the permanent magnet coupler corresponding to this triplet.

[0008] Optionally, the analysis and description of the permanent magnet coupler's operating state corresponding to one of the preset triplets in the preset database, obtained based on various temperature similarities, various distance similarities, and various rotational speed slip similarities, further includes: When there is one and only one temperature similarity exceeding the first temperature similarity threshold, one and only one distance similarity exceeding the first distance similarity threshold, and one and only one speed slip similarity exceeding the first speed slip similarity threshold, it is determined whether the preset temperature change curve corresponding to the temperature similarity exceeding the first temperature similarity threshold, the preset change curve of relative distance change corresponding to the distance similarity exceeding the first distance similarity threshold, and the preset speed slip change curve corresponding to the speed slip similarity exceeding the first speed slip similarity threshold are in the same triplet. If not, then... The triplet containing the preset temperature change curve corresponding to the temperature similarity exceeding the first temperature similarity threshold is obtained, and this triplet is called the first triplet. The triplet containing the preset change curve of the relative distance change corresponding to the distance similarity exceeding the first distance similarity threshold is called the second triplet. The triplet containing the preset speed slip change curve corresponding to the speed slip similarity exceeding the first speed slip similarity threshold is called the third triplet. The working status analysis descriptions of the permanent magnet couplers in the first ternary group, the second ternary group, and the third ternary group are obtained respectively. Choose one permanent magnet coupler operating status analysis description from the first three groups, the second three groups, and the third three groups as the final permanent magnet coupler operating status analysis description.

[0009] Optionally, one permanent magnet coupler operating status analysis description may be selected from the operating status analysis descriptions of the first ternary group, the second ternary group, and the third ternary group as the final permanent magnet coupler operating status analysis description, including: Obtain the grade label database, which includes at least two different grades of grade labels. Each permanent magnet coupler operating status analysis description is set with one grade label. Select the permanent magnet coupler operating status analysis description with the highest grade label from the permanent magnet coupler operating status analysis descriptions of the first ternary group, the second ternary group, and the third ternary group as the final permanent magnet coupler operating status analysis description.

[0010] Optionally, when the permanent magnet coupler operation status analysis descriptions of the first ternary group, the second ternary group, and the third ternary group have the same level label, selecting one permanent magnet coupler operation status analysis description from the three groups as the final permanent magnet coupler operation status analysis description further includes: The semantic information of the permanent magnet coupler working state analysis description of the first triplet is obtained by semantic recognition. This semantic information is called the first semantic information. The semantic information of the permanent magnet coupler operating state analysis description of the second triplet is obtained by semantic recognition. This semantic information is called the second semantic information. The semantic information of the permanent magnet coupler operating state analysis and description of the third triplet is obtained by semantic recognition. This semantic information is called the third semantic information. If only one of the first, second, and third semantic information contains action information, then the permanent magnet coupler working state analysis description corresponding to the semantic information containing action information is obtained as the final permanent magnet coupler working state analysis description.

[0011] Optionally, when the permanent magnet coupler operation status analysis descriptions of the first ternary group, the second ternary group, and the third ternary group have the same level label, selecting one permanent magnet coupler operation status analysis description from the three groups as the final permanent magnet coupler operation status analysis description further includes: If at least two of the first, second, and third semantic information contain action information, then Obtain the action database, which includes at least one action information and its sequence number; The semantic information corresponding to the action information with the smaller sequence number is obtained as the permanent magnet coupler working state analysis description, which is then used as the final permanent magnet coupler working state analysis description.

[0012] This application also provides a central controller, which includes: Temperature change curve acquisition module, which is used to acquire the temperature change curve within a first preset time period through a wireless temperature sensor. The relative distance change curve acquisition module is used to acquire the relative distance change curve between the conductor disk and the magnet disk within a first preset time period through a distance sensor. The speed slip change curve acquisition module is used to acquire the speed of the conductor disk and the speed of the magnet disk through the speed sensor, and to acquire the speed slip through the speed of the conductor disk and the speed of the magnet disk, thereby acquiring the speed slip change curve within a first preset time period. The preset database acquisition module is used to acquire a preset database. The preset database includes at least one preset triplet and a permanent magnet coupler working status analysis description corresponding to each preset triplet. Each preset triplet includes a preset temperature change curve, a preset change curve of relative distance change, and a preset speed slip change curve. The final permanent magnet coupler working status analysis and description acquisition module is used to obtain the permanent magnet coupler working status analysis and description corresponding to one of the three groups in the preset database based on the temperature change curve, the relative distance change curve between the conductor disk and the magnet disk and the speed slip change curve within the first preset time period. The permanent magnet coupler current status acquisition module is used to obtain the current status of the permanent magnet coupler based on the final permanent magnet coupler working status analysis description.

[0013] Beneficial effects:

[0014] The permanent magnet coupler lifecycle management system of this application detects the temperature of the permanent magnet coupler, the relative distance between the conductor disk and the magnet disk, and the rotational speed of the conductor disk and the magnet disk by setting up wireless temperature sensors, distance sensors, and speed sensors, and transmits them to the main controller. This allows the main controller to obtain the current status of the permanent magnet coupler based on the information transmitted by the wireless temperature sensors, distance sensors, and speed sensors, thereby understanding the current status of the permanent magnet coupler. Attached Figure Description

[0015] Figure 1 This is a flowchart illustrating a permanent magnet coupler lifecycle management system according to an embodiment of this application.

[0016] Figure 2 It is used to implement Figure 1 A schematic diagram of an electronic device illustrating the lifecycle management method for permanent magnet couplers. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0018] Figure 1 This is a flowchart illustrating a permanent magnet coupler lifecycle management system according to an embodiment of this application.

[0019] like Figure 1 The permanent magnet coupler lifecycle management system shown includes a wireless temperature sensor, a distance sensor, a speed sensor, and a main controller. A wireless temperature sensor is installed on the conductor disk and / or magnet disk to detect the temperature of the conductor disk and / or magnet disk; Distance sensors are installed on the conductor disk and / or magnet disk to detect changes in the relative distance between the conductor disk and the magnet disk; Rotational speed sensors are respectively installed on the conductor disk and the magnet disk to obtain the rotational speed of the conductor disk and the rotational speed of the magnet disk; The main controller is connected to the wireless temperature sensor, distance sensor, and speed sensor respectively, and is used to acquire the information transmitted by the wireless temperature sensor, distance sensor, and speed sensor, and to obtain the current state of the permanent magnet coupler based on the information transmitted by the wireless temperature sensor, distance sensor, and speed sensor.

[0020] The permanent magnet coupler lifecycle management system of this application detects the temperature of the permanent magnet coupler, the relative distance between the conductor disk and the magnet disk, and the rotational speed of the conductor disk and the magnet disk by setting up wireless temperature sensors, distance sensors, and speed sensors, and transmits them to the main controller. This allows the main controller to obtain the current status of the permanent magnet coupler based on the information transmitted by the wireless temperature sensors, distance sensors, and speed sensors, thereby understanding the current status of the permanent magnet coupler.

[0021] This application also provides a method for managing the lifecycle of a permanent magnet coupler, which includes: The temperature change curve within a first preset time period is obtained using a wireless temperature sensor. The relative distance between the conductor disk and the magnet disk within a first preset time period is obtained using a distance sensor; The rotational speed of the conductor disk and the rotational speed of the magnet disk are obtained by a speed sensor, and the speed slip is obtained by the rotational speed of the conductor disk and the rotational speed of the magnet disk, thereby obtaining the speed slip change curve within a first preset time period. Obtain a preset database, which includes at least one preset triplet and a working state analysis description of the permanent magnet coupler corresponding to each preset triplet. Each preset triplet includes a preset temperature change curve, a preset change curve of relative distance change, and a preset speed slip change curve. Based on the temperature change curve, the relative distance change curve between the conductor disk and the magnet disk, and the speed slip change curve within the first preset time period, the permanent magnet coupler working status analysis description corresponding to one of the preset triplets in the preset database is obtained as the final permanent magnet coupler working status analysis description. The current state of the permanent magnet coupler is obtained based on the final permanent magnet coupler operating state analysis description.

[0022] In this embodiment, the first preset time period can be within 3 minutes, within 1 minute, or other preset time periods.

[0023] In this embodiment, the permanent magnet coupler lifecycle management method of this application can be performed periodically, that is, the various curves mentioned above can be obtained within a first preset time period at regular intervals.

[0024] For example, in the operation of a permanent magnet coupler, the first preset time period is 0 to 1 minute after startup, so as to obtain the various curves mentioned above. Then, after 20 seconds, i.e., 1 minute 20 seconds to 2 minutes 20 seconds, it can be used as the second preset time period.

[0025] It is understandable that there can be no interval between the first and second preset time periods; that is, the second preset time period can be started immediately after the first preset time period is completed.

[0026] In this embodiment, the preset database can be the changes of the above-mentioned curves under various conditions obtained through testing. For example, a set of preset temperature change curves, preset distance change curves, and preset speed slip change curves are formed when the permanent magnet coupler is working normally within 1 minute of starting up, within the range of 0 to 10 degrees.

[0027] Alternatively, a set of preset temperature change curves, preset relative distance change curves, and preset speed slip change curves can be formed during normal operation of the permanent magnet coupler within 2 to 3 minutes of startup.

[0028] Alternatively, within 2 to 3 minutes of startup, a set of preset temperature change curves, preset relative distance change curves, and preset speed slip change curves can be formed, which are used to describe the situation where the conductor disk is damaged due to a rapid increase in the slip between the conductor disk and the magnet disk and the conductor disk is damaged by the rapid increase in temperature caused by the eddy current.

[0029] Understandably, here, we can try to use an exhaustive approach to form various triples, thereby encompassing all the possibilities of the permanent magnet coupler.

[0030] In this embodiment, each curve in each triplet is the same as the first preset time period on the time axis. That is, if the first preset time period is one minute, then each curve in the triplet is also a curve within one minute.

[0031] In this embodiment, the final permanent magnet coupler working status analysis description is set by experts and is used to describe the current permanent magnet coupler status or the actions that need to be performed. For example, within the range of 0 to 10 degrees, the preset temperature change curve, the preset relative distance change curve, and the preset speed slip change curve form a triplet during normal permanent magnet coupler operation from the start to 1 minute. The corresponding current permanent magnet coupler status can be described as: the permanent magnet coupler is working normally, and the working time is from the start, and the working time is approximately within 1 to 10 minutes.

[0032] In practical applications, the final permanent magnet coupler's operating status analysis can be displayed on a monitor, allowing users to see it.

[0033] For example, a set of preset temperature change curves, preset relative distance change curves, and preset speed slip change curves, which are used to describe the current permanent magnet coupler status under the condition that the conductor disk and magnet disk are damaged due to the rapid temperature rise caused by eddy currents within 2 to 3 minutes of startup, can be used to describe the permanent magnet coupler as follows: the permanent magnet coupler is not working properly, the temperature is too high, the temperature is A degrees, the speed slip is B, and the suggestion is to check if there is a problem with the load.

[0034] In practical applications, the final permanent magnet coupler's operating status analysis can be displayed on a monitor, allowing users to see it.

[0035] This method uses three curves—temperature change curve, relative distance change curve between conductor disk and magnet disk, and rotational speed slip curve—to make a judgment. It can not only determine whether the permanent magnet coupler has a fault or other problems, but also identify the problem points and handling methods by comparing different curves. This solves the problem that existing technologies cannot detect and warn of permanent magnet couplers.

[0036] In this embodiment, the permanent magnet coupler operating status analysis and description obtained from one of the preset triplets in the preset database based on the temperature change curve, the relative distance change curve between the conductor disk and the magnet disk, and the rotational speed slip change curve within the first preset time period includes: The similarity between the temperature change curve within the first preset time period and each preset temperature change curve is obtained, and this similarity is called temperature similarity. The similarity between the curve of relative distance change within the first preset time period and the preset curve of relative distance change is obtained. This similarity is called distance similarity. The similarity between the speed slip change curve within the first preset time period and each preset speed slip change curve is obtained, and this similarity is called speed slip similarity. Based on the similarity of various temperatures, distances, and speed slip, the working state analysis description of the permanent magnet coupler corresponding to one of the three pairs in the preset database is obtained.

[0037] In this embodiment, curves are paired by comparing their similarity to determine which specific triplet is applicable.

[0038] In this embodiment, the analysis and description of the permanent magnet coupler's operating state corresponding to one of the preset triplets in the preset database, obtained based on various temperature similarities, various distance similarities, and various rotational speed slip similarities, includes: The number of temperature similarities exceeding a first temperature similarity threshold, the number of distance similarities exceeding a first distance similarity threshold, and the number of speed slip similarities exceeding a first speed slip similarity threshold are obtained. When there is one and only one temperature similarity exceeding the first temperature similarity threshold, one and only one distance similarity exceeding the first distance similarity threshold, and one and only one speed slip similarity exceeding the first speed slip similarity threshold, it is determined whether the preset temperature change curve corresponding to the temperature similarity exceeding the first temperature similarity threshold, the preset change curve of relative distance change corresponding to the distance similarity exceeding the first distance similarity threshold, and the preset speed slip change curve corresponding to the speed slip similarity exceeding the first speed slip similarity threshold are in the same triplet. If so, then... Obtain the operating status analysis description of the permanent magnet coupler corresponding to this triplet.

[0039] When all the curves calculated by similarity are located in the same triplet, it means that the characteristics they embody are completely consistent with the triplet. In this case, the permanent magnet coupler working state analysis description corresponding to the triplet can be directly used as the final permanent magnet coupler working state analysis description.

[0040] In some embodiments, the following situations may also occur: When there is one and only one temperature similarity exceeding the first temperature similarity threshold, one and only one distance similarity exceeding the first distance similarity threshold, and one and only one speed slip similarity exceeding the first speed slip similarity threshold, it is determined whether the preset temperature change curve corresponding to the temperature similarity exceeding the first temperature similarity threshold, the preset change curve of relative distance change corresponding to the distance similarity exceeding the first distance similarity threshold, and the preset speed slip change curve corresponding to the speed slip similarity exceeding the first speed slip similarity threshold are in the same triplet. If not, then... The triplet containing the preset temperature change curve corresponding to the temperature similarity exceeding the first temperature similarity threshold is obtained, and this triplet is called the first triplet. The triplet containing the preset change curve of the relative distance change corresponding to the distance similarity exceeding the first distance similarity threshold is called the second triplet. The triplet containing the preset speed slip change curve corresponding to the speed slip similarity exceeding the first speed slip similarity threshold is called the third triplet. The working status analysis descriptions of the permanent magnet couplers in the first ternary group, the second ternary group, and the third ternary group are obtained respectively. Choose one permanent magnet coupler operating status analysis description from the first three groups, the second three groups, and the third three groups as the final permanent magnet coupler operating status analysis description.

[0041] For example, if a complex operating condition occurs (e.g., the air gap of the coupler disappears, the conductor disk and the magnet disk rub against each other, and the slip between the conductor disk and the magnet disk increases).

[0042] If we set up a triplet to account for the possibility of both of the above situations occurring simultaneously, then the curves corresponding to the composite operating condition will also appear in the same triplet.

[0043] However, if our triplet does not take this operating condition into account, and we only consider the following two operating conditions: Operating condition 1: The air gap of the coupler disappears, causing the conductor disk and the magnet disk to rub against each other; Condition 2: The conductor disk and the magnet disk rub against each other, and the slip between the conductor disk and the magnet disk increases.

[0044] In this case, it is possible that the preset curve of the relative distance change corresponding to the curve of the relative distance change between the conductor disk and the magnet disk is not in the same triplet as the preset curve of the speed slip change corresponding to the curve of the speed slip change.

[0045] For example, suppose there are three triplets in the preset database: triplet 1 (A1 (preset temperature change curve), B1 (preset change curve of relative distance change), C1 (preset speed slip change curve); triplet 2 (A2 (preset temperature change curve), B2 (preset change curve of relative distance change), C2 (preset speed slip change curve); and triplet 3 (A3 (preset temperature change curve), B3 (preset change curve of relative distance change), C3 (preset speed slip change curve)).

[0046] Assume that the temperature change curve within the first preset time period is A11, the relative distance change curve between the conductor disk and the magnet disk is B11, and the speed slip change curve is C11.

[0047] In this situation, the following scenarios may occur: Scenario 1: If the similarity between A11 and A1 exceeds the first temperature similarity threshold; the similarity between B11 and B1 exceeds the first distance similarity threshold; and the similarity between C11 and C1 exceeds the first speed slip similarity threshold, then the temperature change curve A11, the relative distance change curve between the conductor disk and the magnet disk, and the speed slip change curve C11 within the first preset time period are all in the same triplet.

[0048] Scenario 2: If the similarity between A11 and A1 exceeds the first temperature similarity threshold; the similarity between B11 and B2 exceeds the first distance similarity threshold; and the similarity between C11 and C3 exceeds the first speed slip similarity threshold, then the temperature change curve A11, the relative distance change curve between the conductor disk and the magnet disk B11, and the speed slip change curve C11 within the first preset time period will each be in different triplets. (It is understood that other situations may occur, such as two curves being in the same triplet and another curve being in a different triplet; these will not be exhaustively listed here.)

[0049] At this point, triplet 1 is the first triplet, triplet 2 is the second triplet, and triplet 3 is the third triplet.

[0050] Choose one permanent magnet coupler operating status analysis description from the first three groups, the second three groups, and the third three groups as the final permanent magnet coupler operating status analysis description.

[0051] In this embodiment, the permanent magnet coupler operating state analysis description selected from the permanent magnet coupler operating state analysis descriptions of the first ternary group, the second ternary group, and the third ternary group as the final permanent magnet coupler operating state analysis description includes: Obtain the grade label database, which includes at least two different grades of grade labels. Each permanent magnet coupler operating status analysis description is set with one grade label. Select the permanent magnet coupler operating status analysis description with the highest grade label from the permanent magnet coupler operating status analysis descriptions of the first ternary group, the second ternary group, and the third ternary group as the final permanent magnet coupler operating status analysis description.

[0052] In this way, a level label is assigned to each triple to distinguish the severity of the problems between the triples. For example, if a triple represents stable operation, its level label is Level 1; if a triple represents potential problems, its level label is Level 2; and if another triple represents a critical problem, its level label is Level 3.

[0053] In this embodiment, a higher level label refers to a higher label level; for example, level three is higher than level two, and level two is higher than level one.

[0054] In this embodiment, when the permanent magnet coupler operation status analysis descriptions of the first ternary group, the second ternary group, and the third ternary group have the same level label, selecting one permanent magnet coupler operation status analysis description from the first, second, and third ternary groups as the final permanent magnet coupler operation status analysis description further includes: The semantic information of the permanent magnet coupler working state analysis description of the first triplet is obtained by semantic recognition. This semantic information is called the first semantic information. The semantic information of the permanent magnet coupler operating state analysis description of the second triplet is obtained by semantic recognition. This semantic information is called the second semantic information. The semantic information of the permanent magnet coupler operating state analysis and description of the third triplet is obtained by semantic recognition. This semantic information is called the third semantic information. If only one of the first, second, and third semantic information contains action information, then the permanent magnet coupler working state analysis description corresponding to the semantic information containing action information is obtained as the final permanent magnet coupler working state analysis description.

[0055] In some embodiments, there may be two or more triples at the same level. In this case, semantic recognition can be used to identify whether they contain action information. For example, it is suggested to shut down or to check if the device is overloaded. The word "check" is a verb, which means that the user needs to perform a certain operation. This semantic recognition method can identify its semantics and thus consider it as action information.

[0056] If two triples need to be selected at the same level, and one triple has action information while the other does not, then the permanent magnet coupler operating state analysis description corresponding to the semantic information including action information is selected as the final permanent magnet coupler operating state analysis description.

[0057] In one embodiment, when the permanent magnet coupler operation status analysis descriptions of the first ternary group, the second ternary group, and the third ternary group have the same level label, selecting one permanent magnet coupler operation status analysis description from the first, second, and third ternary groups as the final permanent magnet coupler operation status analysis description further includes: If at least two of the first, second, and third semantic information contain action information, then Obtain the action database, which includes at least one action information and its sequence number; The semantic information corresponding to the action information with the smaller sequence number is obtained as the permanent magnet coupler working state analysis description, which is then used as the final permanent magnet coupler working state analysis description.

[0058] For example, in one embodiment, the action database includes three action information items, such as: first action information: check load; second action information: reduce a certain speed; third action information: power off. In this case, the sequence numbers of the three are: 1. Third action information; 2. Second action information; 3. Third action information.

[0059] Among them, the one with the smaller sequence number is the third action information. At this point, the semantic information corresponding to the action information with the smaller sequence number is obtained as the permanent magnet coupler working state analysis description, which is used as the final permanent magnet coupler working state analysis description. That is, the semantic information corresponding to the third action information is obtained as the permanent magnet coupler working state analysis description, which is used as the final permanent magnet coupler working state analysis description.

[0060] This application also provides a main controller, which includes a temperature change curve acquisition module, a relative distance change curve acquisition module, a speed slip change curve acquisition module, a preset database acquisition module, a final permanent magnet coupler operating state analysis and description acquisition module, and a permanent magnet coupler current state acquisition module. The temperature change curve acquisition module is used to acquire the temperature change curve within a first preset time period via a wireless temperature sensor. The relative distance change curve acquisition module is used to acquire the relative distance change curve between the conductor disk and the magnet disk within a first preset time period through a distance sensor; The speed slip change curve acquisition module is used to acquire the speed of the conductor disk and the speed of the magnet disk through the speed sensor, and to acquire the speed slip through the speed of the conductor disk and the speed of the magnet disk, thereby acquiring the speed slip change curve within a first preset time period. The preset database acquisition module is used to acquire a preset database. The preset database includes at least one preset triplet and a permanent magnet coupler working status analysis description corresponding to each preset triplet. Each preset triplet includes a preset temperature change curve, a preset change curve of relative distance change, and a preset speed slip change curve. The final permanent magnet coupler working status analysis and description acquisition module is used to obtain the permanent magnet coupler working status analysis and description corresponding to one of the three groups in the preset database based on the temperature change curve, the relative distance change curve between the conductor disk and the magnet disk and the speed slip change curve within the first preset time period, as the final permanent magnet coupler working status analysis and description. The permanent magnet coupler current status acquisition module is used to obtain the current status of the permanent magnet coupler based on the final permanent magnet coupler working status analysis description.

[0061] It should be noted that the foregoing explanation of the method embodiments also applies to the apparatus of this embodiment, and will not be repeated here.

[0062] This application also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein the processor implements the above-described permanent magnet coupler lifecycle management method when executing the computer program.

[0063] This application also provides a computer-readable storage medium storing a computer program that, when executed by a processor, enables the implementation of the above-described permanent magnet coupler lifecycle management method.

[0064] Figure 2 This is an exemplary structural diagram of an electronic device capable of implementing the permanent magnet coupler lifecycle management method provided in one embodiment of this application.

[0065] like Figure 2As shown, the electronic device includes an input device 501, an input interface 502, a central processing unit 503, a memory 504, an output interface 505, and an output device 506. The input interface 502, central processing unit 503, memory 504, and output interface 505 are interconnected via a bus 507. The input device 501 and output device 506 are connected to the bus 507 via the input interface 502 and output interface 505, respectively, and thus connected to other components of the electronic device. Specifically, the input device 504 receives input information from the outside and transmits it to the central processing unit 503 via the input interface 502. The central processing unit 503 processes the input information based on computer-executable instructions stored in the memory 504 to generate output information, temporarily or permanently storing the output information in the memory 504, and then transmitting the output information to the output device 506 via the output interface 505. The output device 506 outputs the output information to the outside of the electronic device for user use.
