[0002] With the development of wind power generation technology, users have put forward higher requirements for corrosion monitoring on blades (blades on discharge fans).

[0003] Traditional corrosion monitoring methods on blades mostly rely on users to manually judge the images of blades to determine whether there is corrosion information. This corrosion monitoring method has great defects, and there will be a phenomenon that manual workers cannot accurately judge the corrosion state on the blades. That is, this corrosion monitoring method will result in low accuracy of corrosion monitoring because manual workers cannot accurately judge the corrosion state on the blades.

[0050] The realization of the purpose of this application, functional features and advantages will be further described in combination with embodiments with reference to the accompanying drawings. Specific embodiments

[0051] It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0052] In order to better understand the technical solution of this application, the following will be described in detail in combination with the drawings of the specification and specific embodiments.

[0053] Common methods for corrosion monitoring on blades are that users manually judge the images 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 onto the fan to collect and judge, or collect the images on the blades and then manually observe the images to determine the corrosion condition. On the one hand, in order to judge the blades, the user needs to climb onto the fan, which makes the corrosion judgment difficult. At the same time, the user will have eye fatigue and misjudgment, and some internal inconspicuous corrosion cannot be judged by the human eye (because generally anti-corrosion substances are used to isolate the air, such as paint, which will cause the problem that the internal corrosion cannot be accurately judged), thus resulting in low accuracy of corrosion monitoring.

[0054] Therefore, based on the deficiencies of the above corrosion monitoring scheme, the corrosion monitoring method of this application is proposed. The solution of the embodiment of this application is: after determining the corrosion judgment mode based on the blade rotation information, in different modes, determine the corrosion monitoring result based on the blade pressure information, preset blade state information and the movement information of the leaf surface moving unit, and determine the corrosion monitoring result based on the blade pressure information and the movement information of the leaf surface moving unit. Because the corrosion condition is judged based on the blade rotation information and the blade pressure information, the problem that the corrosion state on the blade cannot be accurately judged manually is avoided, and thus the accuracy of corrosion monitoring can be improved.

[0055] 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 that can realize 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.

[0056] Based on this, the embodiment of this application provides a corrosion monitoring method, referring to Figure 1 , Figure 1 It is a schematic flowchart of the first embodiment of the corrosion monitoring method of this application.

[0057] Referring to Figure 1 , this application provides a corrosion monitoring method, which is applied to a corrosion monitoring device. The corrosion monitoring device includes a corrosion sensing unit and a leaf surface moving unit. Each corrosion monitoring device is arranged on a blade. In the first embodiment of the corrosion monitoring method, the corrosion monitoring method includes:

[0058] Step S10, obtaining the corrosion monitoring basis information collected by the corrosion sensing unit, where the corrosion monitoring basis information includes blade rotation information and blade pressure information;

[0059] Step S20, determining a corrosion judgment mode according to the blade rotation information. 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;

[0060] 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 fan. That is, when a fan 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 simultaneously, and the corrosion monitoring method of this application can be executed simultaneously, so as to accurately determine which position on which blade. The corrosion monitoring device includes a corrosion sensing unit and a leaf 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 realized by using corresponding rotation speed sensors and pressure sensors, or other instruments for collecting rotation speed and pressure can also be used, which is not limited here. The leaf surface moving unit can be two mutually attracting moving devices, such as sensors that can move and monitor the distance in real time, so as to determine whether the distance on the leaf surface has changed to determine whether it is corroded. It can also directly be two sensors that do not attract each other but ensure that they can move along the blade surface, such as sensors that can move and monitor the distance in real time, which can ensure that they are attached to the blade surface, and the attachment force of the sensor will not cause damage to the corroded position, that is, ensure that it is attached close to the blade surface. For example, the sensor bottom itself will detect the blade image, and then apply a corresponding force (such as increasing the attraction appropriately if the distance is far, and vice versa reducing the attraction. At this time, one sensor is on the blade surface, and the other attracting sensor can be arranged 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 attach to the leaf surface. At this time, when monitoring corrosion, it can be determined whether there are corroded protrusions and depressions, so as to ensure the accuracy and intelligence of corrosion monitoring. Because at this time, based on the corrosion sensing unit and the leaf surface moving unit in the corrosion monitoring device, information on the blade is collected, and then the monitoring of the blade is realized, so as to improve the accuracy of blade corrosion monitoring.

[0061] In this embodiment, when corrosion monitoring is required (the corrosion monitoring method of this embodiment is executed regularly or at intervals), the corrosion monitoring basis information collected by the corrosion sensing unit is obtained, and then the corrosion monitoring of the blade is carried out based on the corrosion monitoring basis information. Among them, the corrosion monitoring basis information includes blade rotation information and blade pressure information. The blade rotation information refers to information such as the rotation speed of the blade, and the blade pressure information refers to the pressure information on the blade surface. That is, a sensor for measuring the rotation speed can be set at the blade connection, so that the rotation speeds of multiple blades can be measured based on one rotation speed sensor. However, the pressure sensor for measuring pressure needs to be set on the inner side close to the blade surface. At this time, pressure sensors can be set at different positions on the blade based on the pressure acquisition range of the pressure sensor. For example, for the entire blade and the pressure acquisition range of the pressure sensor, only two pressure sensors need to be set. Then, by setting the pressure sensors on the blade, the pressure value on the blade surface can be collected. Of course, four pressure sensors can be set for both sides of the blade to achieve pressure acquisition on both sides. After obtaining the blade rotation information, the corrosion judgment mode is directly determined based on the blade rotation information, mainly to determine whether there is a phenomenon of mass increase or mass decrease on the blade based on the blade rotation information, so as to determine the first corrosion judgment mode of blade mass increase and the second corrosion judgment mode of blade mass decrease, and initially determine the blades that may be corroded through the blade mass, providing the blades that need to be monitored key points for subsequent corrosion monitoring. At the same time, the entire process can avoid the defects of manual monitoring, thereby improving the accuracy of corrosion monitoring.

[0062] Step S30, when the corrosion judgment mode is the first corrosion judgment mode, determine the corrosion monitoring result according to the blade pressure information, the preset blade state information, and the movement information of the blade surface movement unit;

[0063] Step S40, when the corrosion judgment mode is the second corrosion judgment mode, determine the corrosion monitoring result according to the blade pressure information and the movement information of the blade surface movement unit.

[0064] In this embodiment, after determining the corrosion judgment mode, it will be controlled in two modes. When the corrosion judgment mode is the first corrosion judgment mode, that is, when 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 movement unit. The blade state information refers to the mass change under different rotational 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. Furthermore, based on the above information, the corrosion monitoring result in the first corrosion judgment mode can be determined. Since the first corrosion judgment mode may be an increase in mass caused by attachments or an increase in mass caused by corrosion, the corrosion or attachments can be accurately identified based on the blade state information and the movement information to ensure the accuracy of corrosion determination. When the corrosion judgment mode is the second corrosion judgment mode, that is, when 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 movement unit. That is, when the mass reduction at this time is caused by corrosion, the specific corrosion location can be determined based on the blade pressure information and the movement information as the corrosion monitoring result. That is, the corrosion monitoring result in this embodiment refers to the specific corrosion location on the blade to accurately determine the corrosion location on the blade to ensure the accuracy of corrosion monitoring.

[0065] In one embodiment, referring to Figure 2 , Figure 2 is a schematic diagram of an implementation process of the corrosion monitoring method of this application. By obtaining the blade rotation-related information, that is, the blade rotation information, the judgment mode can be determined based on the blade rotation-related information, that is, to determine the first corrosion judgment mode in which the blade mass increases or the second corrosion judgment mode in which the blade mass decreases. When the mode is the weight loss judgment mode, it will be judged based on the pressure information and the movement information in the relevant information. That is, at this time, the process of determining the corrosion monitoring result according to the blade pressure information and the movement information of the blade surface movement unit is executed; when the mode is the weight gain judgment mode, it will be judged based on the pressure information, rules, and movement information in the relevant information. That is, at this time, the process 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 movement unit is executed. At this time, considering the influence of different mass situations on the judgment and avoiding the problem that manual operation cannot accurately judge the corrosion state on the blade, the accuracy of corrosion monitoring can be improved.

[0066] In this embodiment, a corrosion monitoring method is provided, which is applied to a corrosion monitoring device. The corrosion monitoring device includes a corrosion sensing unit and a leaf surface moving unit. Each corrosion monitoring device is arranged on a leaf. The corrosion monitoring method includes: obtaining corrosion monitoring basis information collected by the corrosion sensing unit, where the corrosion monitoring basis information includes leaf rotation information and leaf pressure information; determining a corrosion judgment mode according to the leaf rotation information, and the corrosion judgment mode includes a first corrosion judgment mode in which the leaf mass increases and a second corrosion judgment mode in which the leaf mass decreases; when the corrosion judgment mode is the first corrosion judgment mode, determining a corrosion monitoring result according to the leaf pressure information, preset leaf state information, and the movement information of the leaf surface moving unit; when the corrosion judgment mode is the second corrosion judgment mode, determining a corrosion monitoring result according to the leaf pressure information and the movement information of the leaf surface moving unit. This corrosion monitoring method determines the corrosion judgment mode based on the leaf rotation information, and then, in different modes, determines the corrosion monitoring result based on the leaf pressure information, preset leaf state information, and the movement information of the leaf surface moving unit, as well as determines the corrosion monitoring result based on the leaf pressure information and the movement information of the leaf surface moving unit. Because it judges the corrosion situation based on the leaf rotation information and leaf pressure information, it avoids the problem that manual operation cannot accurately judge the corrosion state on the leaf, and thus can improve the accuracy of corrosion monitoring.

[0067] Further, based on the first embodiment of the present application above, a second embodiment of the corrosion monitoring method of the present application is proposed. In this embodiment, in step S20 above, the leaf rotation information includes a first rotation speed value and a limit rotation speed value of each leaf. The step of determining the corrosion judgment mode according to the leaf rotation information includes:

[0068] Step S21, determining a quasi-corroded leaf based on the limit rotation speed value in the first rotation speed value, and determining a first leaf mass corresponding to the quasi-corroded leaf in a preset rotation speed-mass correspondence table, where the quasi-corroded leaf includes a leaf whose first rotation speed value does not match the limit rotation speed value;

[0069] Step S22, when the first leaf mass is greater than a preset maximum leaf mass, determining the first corrosion judgment mode as the corrosion judgment mode;

[0070] Step S23, when the first leaf mass is less than a preset minimum leaf mass, determining the second corrosion judgment mode as the corrosion judgment mode.

[0071] In this embodiment, it is determined that the corrosion judgment mode is based on the blade quality. By determining the blades in the first rotational speed value that do not match the limit rotational speed value as the blades to be corroded, since the first rotational speed value collects the rotational speed values of each blade, the rotational speed value corresponding to the blade to be corroded can be determined in the first rotational speed value. Then, based on the rotational speed value corresponding to the blade to be corroded, the first blade quality is determined in the preset rotational speed-quality correspondence table. Further, based on the first blade quality corresponding to each blade to be corroded, the corrosion judgment mode is determined. The rotational speed-quality correspondence table refers to a table corresponding to different rotational speeds. For example, when the output rotational speed is A and the actual rotational speed is B, the blade quality is (A - B) * M, where M is a fixed value. That is, considering the relationship between the actual rotational speed, the output rotational speed, and the quality, a rotational speed-quality correspondence table can be set in advance to directly determine. At this time, the output rotational speed A is a fixed value. That is, the corrosion monitoring method of this embodiment is executed at the output rotational speed A to directly determine the blade quality based on the actual rotational speed. The limit rotational speed value refers to the rotational speed range that should be output at the output rotational speed A. For example, if the actual rotational speed is greater than the limit rotational speed value, it is determined that the rotational speed of the blade has changed due to the quality. The first blade quality refers to the quality of the blade to be corroded. At this time, the first blade quality will be judged. When the first blade quality is greater than the preset maximum blade quality, the first corrosion judgment mode is determined as the corrosion judgment mode. On the contrary, when the first blade quality is less than the preset minimum blade quality, the second corrosion judgment mode is determined as the corrosion judgment mode. The preset maximum blade quality refers to the maximum blade quality defined by the user in advance, and the preset minimum blade quality refers to the minimum blade quality defined by the user in advance, to determine the corrosion judgment mode, so as to facilitate the subsequent targeted judgment of the corrosion situation. It should be noted that it can also be directly compared with the limit rotational speed value (including the maximum limit rotational speed value and the minimum limit rotational speed value). When the blade to be corroded is greater than the maximum limit rotational speed value, the first corrosion judgment mode is determined as the corrosion judgment mode, and vice versa, the second corrosion judgment mode is determined as the corrosion judgment mode, that is, the blade quality is directly judged by the driving effect of the output rotational speed. There is also a way to directly determine the magnitude relationship of the blade quality, that is, directly collect the speed of the blade when it is rotating downward as the first rotational speed value, and then determine which first rotational speed value when the blade is descending does not match the theoretical value according to the force between the blades themselves (the force relationship can be considered to determine). Then, when it is determined that this non-conforming situation is caused by the excessive or too small quality of the blade when descending, the corrosion judgment mode is directly determined. Other methods for judging the blade quality can also be used to determine the corrosion judgment mode.

[0072] Furthermore, based on the first embodiment and / or the second embodiment of the present application described above, a third embodiment of the corrosion monitoring method of the present application is proposed. In this embodiment, in step S30, the blade state information includes the mass change value of the blade and the current environmental state of the blade under a preset rotational speed control. 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:

[0073] Step S31, determining the first quasi-corroded blade corresponding to the first corrosion judgment mode, and determining the first mass change value of the first quasi-corroded blade, where the first mass change value includes the mass change value of the first quasi-corroded blade;

[0074] 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 gain environment, determining the corrosion monitoring result according to the blade pressure information;

[0075] Step S33, when the mass change value matches the preset change threshold information or the current environmental state matches the preset weight gain environment, determining the corrosion monitoring result according to the movement information of the blade surface moving unit.

[0076] In this embodiment, when the first corrosion judgment mode determined to be an increase in the blade mass is adopted, the first pseudo-corroded blade corresponding to the first corrosion judgment mode, that is, the blade with an increased mass, is determined, and the first mass change value of the first pseudo-corroded blade is determined. The first mass change value includes the mass change value of the first pseudo-corroded blade. The mass change value refers to the mass change of the blade under a preset rotational speed control (such as the maximum rotational speed control defined by the user, at which time the attached matter can be separated from the blade), such as the mass change of the blade at the maximum rotational speed of the blade. At this time, it can be determined whether the increased mass is caused by the attached matter. It should be noted that since the blades need to be cleaned regularly, the blades will not continuously cause an increase in mass. The current environmental state refers to the current environment of the fan, such as snowing, sandstorm state, etc. When the mass change value does not match the preset change threshold information (that is, there is no attached matter), and the current environmental state does not match the preset weight-increasing environment (that is, there is no environment with attached matter), the corrosion monitoring result is determined based on the blade pressure information. The change threshold information refers to the minimum mass for detaching the attached matter. For example, under the rotational speed control, the blade can change by S mass, that is, S mass of attached matter detaches from the blade. The weight-increasing environment refers to the defined environment that will cause an increase in the blade, such as snowing and temperature drop. That is, at this time, it is determined that the increase in the blade mass is not caused by the attached matter, but there is a corroded position (chemical reaction causes mass increase), and thus the corrosion monitoring result can be directly determined based on the blade pressure information. On the contrary, when one of the two pieces of 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 an attached matter), or the current environmental state matches the preset weight-increasing environment (that is, there is an environment with attached matter), it is determined that the increased mass may be caused by corrosion or may be caused by the attached matter. Furthermore, it is necessary to consider the movement information of the leaf surface moving unit to determine the corrosion monitoring result. By detecting the environment and the attached matter, the possible state of the blade can be determined, and the corrosion state of the blade can be monitored specifically based on the possible state to ensure the accuracy of the corrosion monitoring.

[0077] Further, the step of determining the corrosion monitoring result according to the blade pressure information includes:

[0078] Step S321, determining the first blade pressure value of the first pseudo-corroded blade in the blade pressure information, where the first blade pressure value includes the blade pressure value of each blade area on the first pseudo-corroded blade in the blade pressure information;

[0079] Step S322, for each blade area, detecting whether the first blade pressure value matches the preset theoretical pressure value;

[0080] Step S323, when the first blade pressure value matches the preset theoretical pressure value, determining that the blade corresponding to the blade area is in a normal state;

[0081] Step S324: When the first blade pressure value does not match the preset theoretical pressure value, it is determined that the blade corresponding to the blade area is in a corroded state.

[0082] Step S325: Take the blade area in the first blade to be corroded that is in the corroded state as the corrosion monitoring result.

[0083] In this embodiment, when it is determined that there is a corroded area on the blade, the corroded area is determined as the 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, where the first blade pressure value includes the blade pressure values of each blade area on the first blade to be corroded in the blade pressure information, that is, by detecting whether the pressure value on the blade is normal to detect whether it is corroded. Because there are wind force factors on both sides of the blade resulting in pressure, if a certain area is corroded, the area becomes thinner or thicker, thereby causing a change in the pressure value acting on this area by the wind force. 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. The pressure correspondence table refers to the correspondence table between the wind force value and the theoretical pressure of each blade area. Then, based on the comparison between the actual pressure value and the theoretical pressure value, it can be determined whether the blade area is corroded. When the first blade pressure value matches the preset theoretical pressure value (within the range of the theoretical pressure value), it is determined that the blade corresponding to the blade area is in a normal state (which means the blade area is not corroded). On the contrary, when the first blade pressure value does not match the preset theoretical pressure value (not within the range of the theoretical pressure value), it is determined that the blade corresponding to the blade area is in a corroded state (which means the blade area is corroded). Then, take the blade area in the first blade to be corroded that is in the corroded state as the corrosion monitoring result, that is, determine the position where the pressure value does not match as the corroded position, so that the corrosion condition of the blade can be intelligently determined based on the pressure value, ensuring the intelligence of corrosion monitoring.

[0084] Furthermore, based on the first embodiment, the second embodiment, and / or the third embodiment of the present application described above, a fourth embodiment of the corrosion monitoring method of the present application is proposed. In this embodiment, in step S30 above, the leaf surface moving unit includes controllable magnetic moving objects arranged on both sides of the leaf. The movement information includes the first actual movement distance and the second actual movement distance of the controllable magnetic moving objects at the target movement position of the leaf (that is, the first actual movement distance of the first controllable magnetic moving object on one side of the target movement position of the leaf and the second actual movement distance of the second controllable magnetic moving object on the other side of the target movement position of the leaf). The step of determining the corrosion monitoring result according to the movement information of the leaf surface moving unit includes:

[0085] Step S331: Determine the first theoretical movement distance and the second theoretical movement distance of the target movement position in the preset distance definition table;

[0086] Step S332: When the first theoretical movement distance matches the first actual movement distance and the second theoretical movement distance matches the second actual movement distance, then use the preset sticky state as the corrosion monitoring result;

[0087] Step S333: When the first theoretical movement distance does not match the first actual movement distance or the second theoretical movement distance does not match the second actual movement distance, then determine the corrosion monitoring result according to the first actual movement distance and the second actual movement distance.

[0088] In this embodiment, when determining the possible corrosion areas on the blade, the corrosion areas are determined based on the movement information as the corrosion monitoring result. Among them, the blade surface movement unit includes controllable magnetic moving objects (such as the sensors that can move and monitor the distance in real time as described in the above embodiment) arranged on both sides of the blade. The movement information includes the first actual movement distance and the second actual movement distance of the controllable magnetic moving object at the target movement position on the blade. The target movement position can be a position predefined on the blade in advance, or there can be multiple positions, and the above steps are respectively executed based on each target movement position. The first actual movement distance and the second actual movement distance refer to the movement distances on both sides of the blade, that is, the controllable magnetic moving objects on both sides of the blade respectively determine an actual movement distance. At this time, the first theoretical movement distance and the second theoretical movement distance of the target movement position can be determined in the preset distance definition table. The distance definition table refers to the movement distance from the start to the end of each position on the blade defined in advance. At this time, the first theoretical movement distance corresponds to the first actual movement distance, and the second theoretical movement distance corresponds to the second actual movement distance. Furthermore, when the first theoretical movement distance matches the first actual movement distance, and the second theoretical movement distance matches the second actual movement distance, that is, the movement distances on both sides of the blade match the theoretical values (that is, within the range of the theoretical values), the preset adhesion state is determined as the corrosion monitoring result. Because the movement condition of the controllable magnetic moving object is to fit the blade surface, and because the controllable magnetic moving object moves frequently, the attachments at the track are relatively soft and do not affect the normal movement of fitting the blade surface. Furthermore, the effects of movement and corrosion monitoring can be greatly ensured. When the first theoretical movement distance does not match the first actual movement distance, or the second theoretical movement distance does not match the second actual movement distance, the corrosion monitoring result is determined based on the first actual movement distance and the second actual movement distance. That is, at this time, corrosion will exist on one side of the blade, resulting in the mismatch between the actual movement distance and the theoretical movement distance (that is, the increase in distance caused by protrusion or depression. A certain accuracy value can be set, and within this accuracy value, it can be considered as an error, while above this accuracy value, it is the result of the actual and theoretical distances). At this time, the position of the corrosion is further determined based on the two actual distances, and this position is used as the corrosion monitoring result to ensure the accuracy of corrosion monitoring.

[0089] Further, the step of determining the corrosion monitoring result according to the first actual movement distance and the second actual movement distance includes:

[0090] 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, determine a first change value of the first actual moving distance and a second change value of the second actual moving distance, and use the blade area where the first change value does not match the second change value as the corrosion monitoring result;

[0091] 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 a first change value of the first actual moving distance and a second change value of the second actual moving distance, and use the first blade area where the first change value does not match a preset first change threshold value and the second blade area where the second change value does not match a preset second change threshold value as the corrosion monitoring result.

[0092] In this embodiment, when corrosion is determined to exist, it will be classified into a combined recognition method. That is, when there is a mismatch between two theoretical distances and the actual distance, the first change value of the first actual moving distance and the second change value of the second actual moving distance will be determined respectively. The first change value refers to the change value of the first actual moving distance during the movement, and the second change value refers to the change value of the second actual moving distance during the movement. Since the two controllable magnetic moving objects move synchronously, if at a certain moment the first change value is greater than the second change value, then at this moment the moving distance of the first controllable magnetic moving object is greater than that of the second controllable magnetic moving object. Then at this time, the first controllable magnetic moving object may move to a convex or concave position (at this time, it is considered that the distances on both sides of the blade are the same and there is no convex or concave position. If there is, it can be defined and distinguished in advance). Conversely, if at a certain moment the first change value is less than the second change value, it is determined that the second controllable magnetic moving object may move to a convex or concave position. That is, the above situation is a mismatch between the first change value and the second change value. Furthermore, the blade area where the first change value and the second change value do not match is used as the corrosion monitoring result, that is, it is determined that the blade area is corroded. When both the two theoretical distances and the actual distance do not match, the first and second change values will also be determined respectively, and then corrosion will be monitored based on the first and second change values. Mainly based on the above method, 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 are used as the corrosion monitoring result. That is, the changes corresponding to the two actual distances are judged respectively, and then compared with the theoretical changes. For example, the theoretical value of the distance change at a certain moment for each target moving position can be set in advance (that is, the second change threshold, which is the theoretical value of the moving change corresponding to the second actual moving distance, and the first change threshold, which is the theoretical value of the moving change corresponding to the first actual moving distance). This moment can select an appropriate time length, such as 1S. Then, the corrosion position can be determined based on the theoretical change value. For example, if it is determined that the second blade area at the 5S position is where the second change value does not match the preset second change threshold, then it can be known that the 5S position is the corrosion area. It should be noted that after determining that the 5S position is the corrosion area, the 6S position will continue to be judged. However, at this time, regardless of how long the 5S position lasts, the 6S position starts timing from 6S. For example, if the 5S position has passed for 1.5S (it should be 6.5S at the original 6S position), but at the 6S position, it is still defined as 6S. Or the second change threshold can be directly shifted backward 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 the corrosion position and the subsequent positions being directly judged as the corrosion positions due to the 0.5S delay, so as to ensure the accuracy of the corrosion monitoring result.

[0093] Furthermore, based on the first embodiment, the second embodiment, the third embodiment, and / or the fourth embodiment of the present application described above, a fifth embodiment of the corrosion monitoring method of the present application is proposed. In this embodiment, with reference to Figure 3 , Figure 3 which is a schematic flowchart of the second embodiment of the corrosion monitoring method of the present application, the step of determining the corrosion monitoring result according to the blade pressure information and the movement information of the blade surface movement unit includes:

[0094] Step a, determine the second pseudo-corroded blade corresponding to the second corrosion judgment mode, and determine the second blade pressure value of the second pseudo-corroded blade in the blade pressure information, where the second blade pressure value includes the blade pressure value of each blade area on the second pseudo-corroded blade in the blade pressure information;

[0095] Step b, determine the third blade area in the second blade pressure value, where the third blade area includes the blade area where the second blade pressure value is less than the preset pressure threshold;

[0096] Step c, determine the third actual movement distance of the movement information in the third blade area, and when the third actual movement distance does not match the preset movement threshold, take the surface corrosion of the third blade area as the corrosion monitoring result;

[0097] Step d, when the third actual movement distance matches the preset movement threshold, take the internal corrosion of the third blade area as the corrosion monitoring result.

[0098] In this embodiment, when the second corrosion judgment mode determined to be a decrease in blade mass is selected, the second pseudo-corroded blade corresponding to the second corrosion judgment mode, that is, the blade with a mass decrease, is determined. Then, the second blade pressure value of the second pseudo-corroded blade is determined from the blade pressure information. Here, the second blade pressure value includes the blade pressure values of each blade area on the second pseudo-corroded blade in the blade pressure information. Subsequently, the third blade area is directly determined. 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 where the value is greater than the preset pressure threshold (in this case, due to mass reduction, this generally does not occur). The preset pressure threshold is the pressure value range defined by the user for each blade area of the blade. Thus, the third blade area can be determined as the corroded area. However, at this time, it is necessary to determine whether it is an internal or external corrosion mode. By determining the third actual movement distance of the movement information in the third blade area, that is, the actual movement distance in the third blade area. Then, when the third actual movement distance does not match the preset movement threshold, the surface corrosion of the third blade area is taken as the corrosion monitoring result. Conversely, when the third actual movement distance matches the preset movement threshold, the internal corrosion of the third blade area is taken as the corrosion monitoring result. That is, based on the comparison between the actual movement distance and the preset movement threshold, internal or surface corrosion is determined. The preset movement threshold refers to the theoretical movement distance that should occur in this 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. Conversely, it is determined that the blade surface is corroded. Thus, the corrosion location and state of the blade can be determined to improve the intelligence and functionality of corrosion monitoring.
