[0018] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The commonly used methods for monitoring corrosion on blades are that users manually judge the image of the blades to determine whether there is corrosion information. After the fan is installed, if it is necessary to judge the corrosion condition of the blades, the user needs to climb up the fan and collect the data for judgment, or collect the image on the blade and then manually observe the image to determine the corrosion condition. On the one hand, in order to judge the blades, the user needs to climb up the fan, which makes it difficult to judge the corrosion. At the same time, the user will suffer from eye fatigue and wrong judgment, and some internal corrosion that is not obvious cannot be judged by the human eye (because anti-corrosion materials are generally used to isolate the air, such as paint, which will make it impossible to accurately judge the internal corrosion), resulting in low accuracy of corrosion monitoring.

[0022] Therefore, based on the shortcomings of the above corrosion monitoring scheme, the corrosion monitoring method of the present application is proposed. The solution of the embodiment of the present application is: after determining the corrosion judgment mode based on the blade rotation information, in different modes, the corrosion monitoring result is determined based on the blade pressure information, the preset blade state information and the movement information of the blade surface moving unit, and the corrosion monitoring result is determined based on the blade pressure information and the movement information of the blade surface moving unit. Because the corrosion situation is judged based on the blade rotation information and the blade pressure information, the problem of manual inability to accurately judge the corrosion state on the blade is avoided, thereby improving the accuracy of corrosion monitoring.

[0023] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a device capable of realizing the above functions, a corrosion monitoring device, etc. The following takes the corrosion monitoring device as an example to illustrate this embodiment and the following embodiments.

[0024] Based on this, the present application embodiment provides a corrosion monitoring method, referring to Figure 1 , Figure 1 This is a schematic flow chart of the first embodiment of the corrosion monitoring method of the present application.

[0025] Reference Figure 1 The present application provides a corrosion monitoring method, which is applied to a corrosion monitoring device, wherein the corrosion monitoring device includes a corrosion sensing unit and a blade moving unit, each of which is arranged on a blade. In a first embodiment of the corrosion monitoring method, the corrosion monitoring method includes: Step S10, obtaining corrosion monitoring basis information collected by the corrosion sensing unit, wherein the corrosion monitoring basis information includes blade rotation information and blade pressure information; Step S20, determining a corrosion judgment mode according to the blade rotation information, the corrosion judgment mode comprising a first corrosion judgment mode in which the blade mass increases and a second corrosion judgment mode in which the blade mass decreases; Exemplarily, the entire corrosion monitoring method is applied to a corrosion monitoring device, and a corrosion monitoring device is arranged on a blade of a wind turbine, that is, when a wind turbine has three blades, a corrosion monitoring device is arranged on each blade. At this time, the information collected or processed by the corrosion monitoring devices on the three blades can be obtained at the same time, and the corrosion monitoring method of the present application can be executed at the same time, so as to accurately determine which position on which blade. The corrosion monitoring device includes a corrosion sensing unit and a blade surface moving unit. The corrosion sensing unit is mainly used to collect the rotation speed of the blade and the pressure value on the blade surface, that is, it can be achieved by using corresponding speed sensors and pressure sensors, or other speed and pressure collection instruments can be used, which is not limited here. The blade surface moving unit can be two mutually attracted moving devices, such as a movable sensor that monitors the distance in real time, so as to determine whether the distance on the blade surface has changed to determine whether it is corroded. It can also be directly two sensors that do not attract each other but can ensure that they can fit the movement of the blade surface, such as a movable sensor that monitors the distance in real time. It can ensure that the sensor fits the surface of the blade and the fitting force of the sensor will not cause damage to the corrosion position, that is, it only needs to ensure that it fits close to the surface of the blade. For example, the bottom of the sensor itself will detect the image of the blade, and then apply the corresponding force (if the distance is far, the attraction will be appropriately increased, otherwise the attraction will be reduced. At this time, one sensor is on the surface of the blade, and the other attracted sensor can be set inside the blade. Then the movement path of the other sensor can be controlled to change the detection path of one sensor) to make the sensor fit on the surface of the blade. At this time, during corrosion monitoring, it can be determined whether there are corroded protrusions and depressions to ensure the accuracy and intelligence of corrosion monitoring. Because at this time, the information on the blade is collected based on the corrosion sensing unit and the blade movement unit in the corrosion monitoring device, and then the blade mode monitoring is realized to improve the accuracy of blade corrosion monitoring.

[0026] In this embodiment, when corrosion monitoring is required (the corrosion monitoring method of this embodiment is executed at a fixed time or interval), the corrosion monitoring basis information collected by the corrosion sensing unit will be obtained, and then the corrosion monitoring of the blade will be performed based on the corrosion monitoring basis information, wherein the corrosion monitoring basis information includes blade rotation information and blade pressure information, the blade rotation information refers to the information such as the rotation speed of the blade, and the blade pressure information refers to the pressure information on the surface of the blade, that is, the sensor for measuring the rotation speed can be set at the connection of the blade, that is, the rotation speed measurement of multiple blades can be achieved based on one rotation speed sensor, but the pressure sensor for measuring the pressure needs to be set on the inner side close to the blade surface. At this time, the pressure sensor can be set at different positions on the blade based on the pressure collection range of the pressure sensor. For example, only two pressure sensors are needed for the entire blade and the pressure collection range of the pressure sensor. Then, the pressure sensor is set on the blade to collect the pressure value on the blade surface. Of course, four pressure sensors can be set on both sides of the blade to realize double-sided pressure collection. After obtaining the blade rotation information, the corrosion judgment mode will be determined directly based on the blade rotation information. It is mainly based on the blade rotation information to determine whether there is a mass increase or mass decrease on the blade, and then to determine the first corrosion judgment mode of increased blade mass and the second corrosion judgment mode of reduced blade mass. The blades that may be corroded are preliminarily determined through the blade quality, which provides the key blades that need to be monitored for subsequent corrosion monitoring. At the same time, the entire process can avoid the defects of manual monitoring to improve the accuracy of corrosion monitoring.

[0027] Step S30, when the corrosion judgment mode is the first corrosion judgment mode, determining a corrosion monitoring result according to the blade pressure information, the preset blade state information and the movement information of the blade surface movement unit; Step S40, when the corrosion judgment mode is the second corrosion judgment mode, determining a corrosion monitoring result according to the blade pressure information and the movement information of the blade surface movement unit.

[0028] In this embodiment, after the corrosion judgment mode is determined, it will be divided into two modes for control. When the corrosion judgment mode is the first corrosion judgment mode, that is, the mass on the blade increases at this time, the corrosion monitoring result will be determined based on the blade pressure information, the preset blade state information and the movement information of the blade surface moving unit. The blade state information refers to the mass change under different speed states and the environment where the blade is located at this time. The movement information refers to the real-time movement distance on the blade surface. Then, based on the above information, the corrosion monitoring result in the first corrosion judgment mode can be determined, because the first corrosion judgment mode may be the mass increase caused by attachments, or the mass increase caused by corrosion. Then, based on the blade state information and movement information, the corrosion or attachment can be accurately identified to ensure the accuracy of corrosion determination. When the corrosion judgment mode is the second corrosion judgment mode, that is, the mass on the blade decreases at this time, the corrosion monitoring result will be determined based on the blade pressure information and the movement information of the blade surface moving unit. That is, at this time, the mass decreases due to corrosion, and the specific corrosion position can be determined as the corrosion monitoring result based on the blade pressure information and movement information. That is, the corrosion monitoring result in this embodiment refers to the specific corrosion position on the blade, so as to accurately determine the corrosion position on the blade to ensure the accuracy of corrosion monitoring.

[0029] In one embodiment, referring to Figure 2 , Figure 2 This is a schematic diagram of an implementation process of the corrosion monitoring method of the present application. By obtaining information related to blade rotation, that is, blade rotation information, a judgment mode can be determined based on the relevant information of blade rotation, that is, a first corrosion judgment mode of blade mass increase or a second corrosion judgment mode of blade mass reduction. When the mode is a weight loss judgment mode, a judgment will be made based on the pressure information and movement information in the relevant information, that is, at this time, a process of determining the corrosion monitoring result according to the blade pressure information and the movement information of the blade surface moving unit is executed; when the mode is a weight gain judgment mode, a judgment will be made based on the pressure information, rules and movement information in the relevant information, that is, at this time, a process of determining the corrosion monitoring result according to the blade pressure information, preset blade state information and the movement information of the blade surface moving unit is executed. At this time, the influence of different quality conditions on the judgment is taken into account, and at the same time, the problem of manual inability to accurately judge the corrosion state on the blade is avoided, thereby improving the accuracy of corrosion monitoring.

[0030] In this embodiment, a corrosion monitoring method is provided, which is applied to a corrosion monitoring device, wherein the corrosion monitoring device includes a corrosion sensing unit and a blade movement unit, and each of the corrosion monitoring devices is arranged on a blade. The corrosion monitoring method includes: obtaining corrosion monitoring basis information collected by the corrosion sensing unit, wherein the corrosion monitoring basis information includes blade rotation information and blade pressure information; determining a corrosion judgment mode according to the blade rotation information, wherein the corrosion judgment mode includes a first corrosion judgment mode in which the blade mass increases and a second corrosion judgment mode in which the blade mass decreases; when the corrosion judgment mode is the first corrosion judgment mode, determining a corrosion judgment mode according to the blade pressure information, the preset blade state information and the blade rotation information; determining a corrosion judgment mode according to the blade rotation information; and determining a corrosion judgment mode according to the blade pressure information, the preset blade state information and the blade rotation information. The movement information of the blade surface moving unit determines the corrosion monitoring result; when the corrosion judgment mode is the second corrosion judgment mode, the corrosion monitoring result is determined according to the blade pressure information and the movement information of the blade surface moving unit. After the corrosion judgment mode is determined based on the blade rotation information, this corrosion monitoring method determines the corrosion monitoring result based on the blade pressure information, preset blade state information and the movement information of the blade surface moving unit in different modes, and determines the corrosion monitoring result based on the blade pressure information and the movement information of the blade surface moving unit. Because the corrosion situation is judged based on the blade rotation information and the blade pressure information, the problem of being unable to accurately judge the corrosion situation on the blade by humans is avoided, thereby improving the accuracy of corrosion monitoring.

[0031] Further, based on the first embodiment of the present application, a second embodiment of the corrosion monitoring method of the present application is proposed. In this embodiment, in the above step S20, the blade rotation information includes a first speed value and a limit speed value of each blade, and the step of determining the corrosion judgment mode according to the blade rotation information includes: Step S21, determining a proposed erosion blade in the first speed value based on the speed limit value, and determining a first blade mass corresponding to the proposed erosion blade in a preset speed mass correspondence table, wherein the proposed erosion blade includes a blade whose first speed value does not match the speed limit value; Step S22, when the first blade mass is greater than a preset maximum blade mass, determining the first corrosion judgment mode as the corrosion judgment mode; Step S23: when the first blade mass is less than a preset minimum blade mass, determining the second corrosion judgment mode as the corrosion judgment mode.

[0032] In the present embodiment, the corrosion judgment mode is determined based on the blade quality. The blades that do not match the limit speed value in the first speed value are determined as the blades to be corroded. Because the first speed value collects the speed value of each blade, the speed value corresponding to the blade to be corroded can be determined in the first speed value, and then the first blade quality is determined in the preset speed quality correspondence table based on the speed value corresponding to the blade to be corroded, and then the corrosion judgment mode is determined based on the first blade quality corresponding to each blade to be corroded. The speed quality correspondence table refers to a table corresponding to different speeds. For example, when the output speed is A and the actual speed is B, the blade quality is (AB)*M, where M is a fixed value, that is, considering the relationship between the actual speed and the output speed and the quality, a speed quality correspondence table can be set in advance to directly determine it. At this time, the output speed A is a fixed value, that is, the corrosion monitoring method of the present embodiment is executed at the output speed A to directly determine the blade quality based on the actual speed. The limit speed value refers to the speed range that should be output at the output speed A. If the actual speed is greater than the limit speed value, it is determined that the blade speed changes due to the quality. The first blade quality refers to the quality of the blade to be corroded. At this time, the quality of the first blade will be judged, so that when the quality of the first blade is greater than the preset maximum blade quality, the first corrosion judgment mode is determined as the corrosion judgment mode. Conversely, when the quality of the first blade is less than the preset minimum blade quality, the second corrosion judgment mode is determined as the corrosion judgment mode, wherein the preset maximum blade quality refers to the maximum blade quality defined in advance by the user, and the preset minimum blade quality refers to the minimum blade quality defined in advance by the user, so as to determine the corrosion judgment mode, so as to facilitate the subsequent targeted judgment of the corrosion situation. It is worth noting that it can also be directly compared with the limiting speed value (including the maximum limiting speed value and the minimum limiting speed value), so that when the blade to be corroded is greater than the maximum limiting speed value, the first corrosion judgment mode is determined as the corrosion judgment mode, otherwise the second corrosion judgment mode is determined as the corrosion judgment mode, so as to directly judge the quality of the blade itself through the driving effect of the output speed. There is another way to directly determine the size relationship of the blade mass, that is, directly collect the speed of the blade when it is in a descending rotation as the first speed value, and then determine which blade's first speed value when descending is inconsistent with the theoretical value based on the force between the blades themselves (it can be determined by considering the force relationship), and then determine whether the inconsistency is caused by the mass of the blade being too large or too small when descending, so as to directly determine the corrosion judgment mode, and the corrosion judgment mode can also be determined for other ways to judge the blade mass.

[0033] Further, based on the first embodiment and / or the second embodiment of the present application, a third embodiment of the corrosion monitoring method of the present application is proposed. In this embodiment, in the above step S30, the blade state information includes the mass change value of the blade and the current environmental state of the blade under the preset speed control, and the step of determining the corrosion monitoring result according to the blade pressure information, the preset blade state information and the movement information of the blade surface moving unit includes: Step S31, determining a first blade to be corroded corresponding to the first corrosion judgment mode, and determining a first mass change value of the first blade to be corroded, wherein the first mass change value includes a mass change value of the first blade to be corroded; Step S32, when the mass change value does not match the preset change threshold information, and the current environmental state does not match the preset weight increase environment, determining the corrosion monitoring result according to the blade pressure information; Step S33, when the mass change value matches the preset change threshold information, or the current environmental state matches the preset weight increase environment, the corrosion monitoring result is determined according to the movement information of the blade surface moving unit.

[0034] In this embodiment, when the first corrosion judgment mode of increased blade mass is determined, the first proposed corrosion blade corresponding to the first corrosion judgment mode, that is, the blade with increased mass, will be determined, and the first mass change value of the first proposed corrosion blade will be determined, wherein the first mass change value includes the mass change value of the first proposed corrosion blade, and the mass change value refers to the mass change of the blade under a preset speed control (such as the maximum speed control defined by the user, at this time, the attachment can be detached from the blade), such as the mass change of the blade at the maximum speed of the blade. At this time, it can be determined whether the mass increase is caused by the attachment. It is worth noting that because the blades need to be cleaned regularly, the blades will not continue to cause mass increase. The current environmental state refers to the current environment of the wind turbine, such as snow, wind and sand, etc. When the mass change value does not match the preset change threshold information (i.e., there is no attachment), and the current environmental state does not match the preset weight increase environment (i.e., there is no environment with attachments attached), the corrosion monitoring result is determined based on the blade pressure information. The change threshold information refers to the minimum mass that can be separated from the attachment. For example, under speed control, the blade can be changed by S mass, that is, attachments with S mass are separated from the blade. The weight increase environment refers to an environment that is defined to cause the blade to increase, such as snowing, cooling, etc., that is, at this time, it is determined that the increase in blade mass is not caused by attachments, but by the presence of corrosion (chemical reactions causing mass increase), and the corrosion monitoring result can be directly determined based on the blade pressure information. On the contrary, when one of the two information does not match the preset value, that is, the mass change value does not match the preset change threshold information (that is, there is attachment), or the current environmental state matches the preset weight increase environment (that is, there is an environment with attachments), it will be determined that the mass increase at this time may be caused by corrosion or attachments, and then it is necessary to consider the movement information of the blade moving unit to determine the corrosion monitoring result, so that the possible state of the blade can be determined through the detection of the environment and attachments, so as to conduct targeted monitoring of the corrosion state of the blade based on the possible state to ensure the accuracy of corrosion monitoring.

[0035] Furthermore, the step of determining the corrosion monitoring result according to the blade pressure information includes: Step S321, determining a first blade pressure value of the first blade to be eroded in the blade pressure information, wherein the first blade pressure value includes a blade pressure value of each blade area on the first blade to be eroded in the blade pressure information; Step S322, for each of the blade regions, detecting whether the first blade pressure value matches a preset theoretical pressure value; Step S323, when the first blade pressure value matches a preset theoretical pressure value, it is determined that the blade corresponding to the blade area is in a normal state; Step S324, when the first blade pressure value does not match the preset theoretical pressure value, determining that the blade corresponding to the blade area is in a corroded state; Step S325: taking the blade region in the corroded state on the first blade to be corroded as a corrosion monitoring result.

[0036] In this embodiment, when it is determined that there is a corrosion area on the blade, the corrosion area will be determined as a corrosion monitoring result based on the blade pressure information, by determining the first blade pressure value of the first blade to be corroded in the blade pressure information, wherein the first blade pressure value includes the blade pressure value of each blade area on the first blade to be corroded in the blade pressure information, that is, detecting whether the pressure value on the blade is normal to detect whether it is corroded, because there will be wind factors and pressure on both sides of the blade, if a certain area is corroded, the area will become thinner or thicker, thereby causing the pressure value of the wind acting on the area to change, and the blade area refers to the area collected by each pressure sensor. Then, for each blade area, it is detected whether the first blade pressure value matches the preset theoretical pressure value, at this time, the wind force value can be determined, and the theoretical pressure value of each blade area corresponding to the wind force value is determined in the pressure correspondence table, and the pressure correspondence table refers to the correspondence table of the wind force value and the theoretical pressure of each blade area, and then the actual pressure value can be compared with the theoretical pressure value to determine whether the blade area is corroded. When the first blade pressure value matches the preset theoretical pressure value (within the range of theoretical pressure values), it is determined that the blade corresponding to the blade area is in a normal state (meaning that the blade area is not corroded); conversely, when the first blade pressure value does not match the preset theoretical pressure value (not within the range of theoretical pressure values), it is determined that the blade corresponding to the blade area is in a corroded state (meaning that the blade area is corroded), and then the blade area in the corroded state on the first simulated corrosion blade is used as the corrosion monitoring result, that is, the position where the pressure value does not match is determined as the corroded position, so that the corrosion condition of the blade can be intelligently determined based on the pressure value, thereby ensuring the intelligence of corrosion monitoring.

[0037] Further, based on the first embodiment, the second embodiment and / or the third embodiment of the present application, a fourth embodiment of the corrosion monitoring method of the present application is proposed. In this embodiment, in the above step S30, the blade surface moving unit includes controllable magnetic moving objects arranged on both sides of the blade, and the movement information includes a first actual moving distance and a second actual moving distance of the controllable magnetic moving object at the target moving position of the blade (i.e., the first actual moving distance of the first controllable magnetic moving object on one side of the target moving position of the blade and the second actual moving distance of the second controllable magnetic moving object on the other side of the target moving position of the blade), and the step of determining the corrosion monitoring result according to the movement information of the blade surface moving unit includes: Step S331, determining a first theoretical moving distance and a second theoretical moving distance of the target moving position in a preset distance definition table; Step S332, when the first theoretical moving distance matches the first actual moving distance, and the second theoretical moving distance matches the second actual moving distance, taking the preset sticky state as the corrosion monitoring result; Step S333: when the first theoretical moving distance does not match the first actual moving distance, or the second theoretical moving distance does not match the second actual moving distance, a corrosion monitoring result is determined according to the first actual moving distance and the second actual moving distance.

[0038] In this embodiment, when it is determined that there may be a corrosion area on the blade, the corrosion area will be determined as a corrosion monitoring result based on the movement information, wherein the blade surface movement unit includes a controllable magnetic moving object arranged on both sides of the blade (such as the movable and real-time distance monitoring sensor described in the above embodiment), and the movement information includes a first actual moving distance and a second actual moving distance of the controllable magnetic moving object at the target moving position of the blade. The target moving position can be a position pre-defined on the blade, or there can be multiple positions, so that the above steps are performed separately based on each target moving position. The first actual moving distance and the second actual moving distance refer to the moving distances on both sides of the blade, that is, the controllable magnetic moving objects on both sides of the blade respectively determine an actual moving distance. At this time, the first theoretical moving distance and the second theoretical moving distance of the target moving position can be determined in the preset distance definition table. The distance definition table refers to the moving distance from the beginning to the end of each position on the blade defined in advance. At this time, the first theoretical moving distance corresponds to the first actual moving distance, and the second theoretical moving distance corresponds to the second actual moving distance. Then, when the first theoretical moving distance matches the first actual moving distance, and the second theoretical moving distance matches the second actual moving distance, that is, the moving distance on both sides of the blade matches the theoretical value (that is, within the range of the theoretical value), the preset sticking state is determined as the corrosion monitoring result, because the moving condition of the controllable magnetic moving object is to fit the blade surface, and because the controllable magnetic moving object moves frequently, the attachment at the track is relatively soft and does not affect the normal movement of fitting the blade surface, thereby greatly ensuring the effect of movement and corrosion monitoring. When the first theoretical moving distance does not match the first actual moving distance, or the second theoretical moving distance does not match the second actual moving distance, the corrosion monitoring result will be determined based on the first actual moving distance and the second actual moving distance. That is, corrosion will exist on one side of the blade, causing the actual moving distance to not match the theoretical moving distance (that is, the increase in distance caused by protrusions or depressions can be set to a certain accuracy value, which can be considered as an error under this accuracy value, and the result caused by the actual and theoretical distances at this accuracy value). At this time, the location of the corrosion will be further determined based on the two actual distances, and this location will be used as the corrosion monitoring result to ensure the accuracy of corrosion monitoring.

[0039] Furthermore, the step of determining the corrosion monitoring result according to the first actual moving distance and the second actual moving distance includes: Step S3331, when the first theoretical moving distance does not match the first actual moving distance, and the second theoretical moving distance matches the second actual moving distance, determining a first change value of the first actual moving distance, and determining a second change value of the second actual moving distance, and taking a blade region where the first change value does not match the second change value as a corrosion monitoring result; Step S3331, when the first theoretical moving distance does not match the first actual moving distance, and the second theoretical moving distance does not match the second actual moving distance, determine the first change value of the first actual moving distance, and determine the second change value of the second actual moving distance, and take the first blade area where the first change value does not match the preset first change threshold, and the second blade area where the second change value does not match the preset second change threshold as corrosion monitoring results.

[0040] In this embodiment, when it is determined that corrosion exists, it is divided into a combined identification method, that is, when there is a mismatch between the two theoretical distances and the actual distances, the first change value of the first actual moving distance and the second change value of the second actual moving distance are determined respectively. The first change value refers to the change value of the first actual moving distance during the moving process, and the second change value refers to the change value of the second actual moving distance during the moving process. Because the two controllable magnetic moving objects move synchronously, if the first change value is greater than the second change value at a certain moment, then the moving distance of the first controllable magnetic moving object at this moment is greater than the moving distance of the second controllable magnetic moving object, then the first controllable magnetic moving object may move to a convex or concave position (at this time, considering that the distances on both sides of the blade are the same, there is no convex or concave position, if there is, it can be defined and distinguished in advance), on the contrary, at a certain moment, the first change value is less than the second change value, then it is determined that the second controllable magnetic moving object may move to a convex or concave position, that is, the above situation is that the first change value does not match the second change value, and then the blade area where the first change value does not match the second change value is taken as the corrosion monitoring result, that is, it is determined that the blade area is corroded. When both theoretical distances do not match the actual distances, the first and second change values ​​will be determined respectively, and then the corrosion will be monitored based on the first and second change values. This is mainly based on the above method, taking the first blade area where the first change value does not match the preset first change threshold, and the second blade area where the second change value does not match the preset second change threshold as the corrosion monitoring result, that is, judging the changes corresponding to the two actual distances respectively, and then comparing them with the theoretical changes. For example, the theoretical value of the distance change of each target moving position at a certain moment can be set in advance (that is, the second change threshold, which is the theoretical value of the movement change corresponding to the second actual moving distance, and the first change threshold, which is the theoretical value of the movement change corresponding to the first actual moving distance). The moment can choose an appropriate duration, such as 1S, and then it can be based on The location of corrosion is determined based on the theoretical change value. For example, if the 5S position is determined to be the second blade area where the second change value does not match the preset second change threshold, then it can be known that the 5S position is a corrosion area. It is worth noting that after the 5S position is determined to be a corrosion area, the 6S position will continue to be judged, but at this time, no matter how long the 5S position lasts, the 6S position starts timing with 6S. For example, the 5S position has gone for 1.5S (originally it should be 6.5S at the 6S position), but it is arbitrarily defined as 6S at the 6S position. The second change threshold can also be directly moved back by 0.5S as a whole to ensure that each second change threshold corresponds to the original position, so as to avoid the 5S position being judged as a corrosion position, and the latter position being directly judged as a corrosion position due to the 0.5S delay, so as to ensure the accuracy of the corrosion monitoring results.

[0041] Further, based on the first embodiment, the second embodiment, the third embodiment and / or the fourth embodiment of the present application, a fifth embodiment of the corrosion monitoring method of the present application is proposed. In this embodiment, referring to Figure 3 , Figure 3 This is a flow chart of a second embodiment of the corrosion monitoring method of the present application, wherein the step of determining the corrosion monitoring result according to the blade pressure information and the movement information of the blade surface movement unit comprises: Step a, determining a second blade to be corroded corresponding to the second corrosion judgment mode, and determining a second blade pressure value of the second blade to be corroded in the blade pressure information, wherein the second blade pressure value includes a blade pressure value of each blade area on the second blade to be corroded in the blade pressure information; Step b, determining a third blade area in the second blade pressure value, wherein the third blade area includes a blade area where the second blade pressure value is less than a preset pressure threshold; Step c, determining a third actual moving distance of the movement information in the third blade area, and when the third actual moving distance does not match a preset movement threshold, taking the surface corrosion of the third blade area as a corrosion monitoring result; Step d: when the third actual movement distance matches a preset movement threshold, taking the internal corrosion of the third blade region as a corrosion monitoring result.

[0042] In this embodiment, when the second corrosion judgment mode of blade mass reduction is determined, the second simulated corrosion blade corresponding to the second corrosion judgment mode will be determined, that is, the blade with reduced mass, and then the second blade pressure value of the second simulated corrosion blade will be determined in the blade pressure information, wherein the second blade pressure value includes the blade pressure value of each blade area on the second simulated corrosion blade in the blade pressure information, and then the third blade area is directly determined, and the third blade area is the blade area where the second blade pressure value is less than the preset pressure threshold. Of course, it can also be the blade area greater than the preset pressure threshold (at this time, due to the reduction in mass, this situation generally does not exist), and the preset pressure threshold is the pressure value range of each blade area of ​​the blade defined by the user. The third blade area can be determined as a corrosion area, but at this time it needs to be determined as an internal or external method, by determining the third actual moving distance of the movement information in the third blade area, that is, the actual moving distance in the third blade area, and then when the third actual moving distance does not match the preset moving threshold, the surface corrosion of the third blade area is taken as the corrosion monitoring result, conversely, when the third actual moving distance matches the preset moving threshold, the internal corrosion of the third blade area is taken as the corrosion monitoring result, that is, based on the comparison of the actual moving distance and the preset moving threshold, it is determined to be internal or surface corrosion, and the preset moving threshold refers to the theoretical moving distance that should be in the third blade area. If the theoretical and actual distances match, that is, within the theoretical range, it can be determined that the blade surface is not corroded, but the inside is corroded, otherwise it is determined that the blade surface is corroded, and then the corrosion position and state of the blade can be determined to improve the intelligence and functionality of corrosion monitoring.
