Referring to fig. 1, an application scenario is schematically shown in the embodiment of the present invention. The electric knife switch in the figure comprises a transmission device 1 and a conductive folding frame, the conductive folding frame is driven to rotate by the transmission device 1, and different circuits can be mutually conducted by the conductive folding frame. The hinge joint of the conductive folding frame is provided with a rotating structure which is a second rotating structure 22, a third rotating structure 23 and a fourth rotating structure 24 respectively, and the transmission device 1 is connected with the conductive folding frame through the first rotating structure 21 and the fifth rotating structure 25. When the electric knife switch operates, the transmission device 1 can drive the conductive folding frame to rotate upwards, and at the moment, the angles of the supporting rods of the conductive folding frame and the rotating structures can change correspondingly, wherein each rotating structure is respectively provided with a corresponding vibration sensor. Each branch of electrically conductive book frame can be according to the difference of circuit in actual use, adjusts electrically conductive position appearance of book frame for electrically conductive book frame can be connected with two different circuits, and at the change of an angle of in-process revolution mechanic and electrically conductive support of book frame, and then make the transformer substation can carry out the switching of circuit. The vibration sensor can detect the vibration of the corresponding rotating structure, and when the vibration of the rotating structure is large, the corresponding rotating structure is proved to be possibly damaged. Based on the characteristics, the risk early warning of the power transformation main equipment is realized.

Referring to fig. 2, a schematic diagram of a risk early warning method for a power transformation main device based on hidden danger factors according to an embodiment of the present application is shown, where an execution subject of the method shown in fig. 2 may be a software and/or hardware device. The execution body of the present application may include, but is not limited to, at least one of: user equipment, network equipment, etc. The user devices may include, but are not limited to, computers, smart phones, personal digital assistants (Persona L D I G I TA L ASS I STANT, abbreviated as PDA), and the above-mentioned electronic devices, etc. The network device may include, but is not limited to, a single network server, a server group of multiple network servers, or a cloud of a large number of computers or network servers based on cloud computing, where cloud computing is one of distributed computing, and a super virtual computer consisting of a group of loosely coupled computers. This embodiment is not limited thereto. The method comprises the steps S1 to S6, and specifically comprises the following steps:

S1, vibration information of all vibration sensors is acquired, and the vibration sensor with the vibration information larger than preset information is determined to be a first abnormal sensor.

In practical application, after the rotating structure takes place problems such as corrosion, jam, often can lead to its vibration condition to change, based on this, this scheme adopts the change of obtaining rotating structure vibration information to monitor whether rotating structure takes place to damage.

The first abnormal sensor refers to a sensor with vibration information in an abnormal state, and preset information can be preset according to actual conditions.

Since the damage to the rotating structure may occur and the damage is too serious to affect the other undamaged rotating structures, and the vibration information of the other undamaged rotating structures is abnormal, the first abnormal sensor may include a sensor whose vibration information itself is abnormal and a sensor whose vibration information is abnormal due to the influence of other sensors.

The sensor with abnormal vibration information can be obtained by acquiring the first abnormal sensor through the method, so that the subsequent continuous acquisition of the position of the sensor with abnormal vibration information is facilitated, and the maintenance of the rotating structure is facilitated.

After passing S1 (the vibration sensors whose vibration information is greater than the preset information are determined as the first abnormal sensors) the method further includes steps S11 to S12, specifically as follows:

s11, acquiring the abnormal number of the first abnormal sensor, if the abnormal number is less than or equal to 3, determining a target detection position point according to the first abnormal sensor, generating early warning information according to the target detection position point, and sending the early warning information to a control terminal for display.

The abnormal number refers to the number of the first abnormal sensors, and the target detection position point refers to the position point where the rotating structure to be detected is damaged.

In practical application, when the abnormal number is less than or equal to 3, it is indicated that at least one of the rotating structures corresponding to the first abnormal sensor is damaged, and the damage degree is still in a controllable state. At the moment, the position point of the damaged rotating structure can be determined through the first abnormal sensor, and early warning information is generated after the target detection position point is obtained and is sent to the control terminal, so that the rotating structure can be overhauled conveniently.

And S12, if the number of the anomalies is greater than 3, generating damage information according to the first anomaly sensor and sending the damage information to a control terminal for display.

In practical application, when the abnormal number is greater than 3, it shows that the rotating structure of the rotating device and the conductive folding frame is damaged seriously, and the rotating structure needs to be overhauled immediately, so that the phenomena of refusing closing, refusing separating, breakage of the transmission mechanism and the like of the isolating switch caused by further damage of the rotating device and the conductive folding frame are prevented. Therefore, when the abnormal number is greater than 3, the scheme can directly generate damage information to the control terminal so as to overhaul the rotating structure in time.

The method generates the early warning information and the damage information, and determines the target detection position point under the early warning condition, so that the damage condition of the rotating structure can be well reflected, the specific position of the rotating structure to be detected can be determined, and the subsequent overhaul of the rotating structure is facilitated.

S11 (the abnormal number of the first abnormal sensors is obtained, if the abnormal number is less than or equal to 3, a target detection position point is determined according to the first abnormal sensors, early warning information is generated according to the target detection position point and is sent to a control terminal for display), the target detection position point can be determined through the following steps:

And S2, if judging that other adjacent vibration sensors of the first abnormal sensors are normal, counting all the first abnormal sensors to generate a first abnormal set, and taking the position points corresponding to all the first abnormal sensors in the first abnormal set as target detection position points.

In practical application, the electric knife switch enables the lines which are not connected with each other to be conducted with each other through the conductive folding frame, vibration of each rotating structure is possibly transmitted through the supporting rods of the conductive folding frame, and vibration amplitude is gradually attenuated when the vibration is transmitted through the supporting rods, in general, vibration attenuation is only carried out under the adjacent supporting rods and cannot be continuously attenuated under the plurality of supporting rods, therefore, when the rotating structure is damaged, the rotating structure connected with the adjacent supporting rods is generally influenced, and the rotating structure connected with the non-adjacent supporting rods is not influenced.

Specifically, based on the above conditions, after the first abnormal sensor is obtained, the vibration information of other sensors adjacent to the first abnormal sensor can be obtained, if the vibration information of the other vibration sensors adjacent to the first abnormal sensor is normal, it is indicated that the vibration information of the first abnormal sensor is not affected by the other vibration information, and is abnormal, then the rotating structure corresponding to the first abnormal sensor is the damaged rotating structure, and then the position point where the rotating structure is located can be determined to be the target detection position point.

Wherein the first abnormal set refers to a set of first abnormal sensors in which vibration information itself is abnormal.

And S3, if the plurality of first abnormal sensors are judged to be adjacent, counting the adjacent first abnormal sensors as second abnormal sensors, generating a second abnormal set, and taking the second abnormal sensor with the largest vibration information in the second abnormal set as a third abnormal sensor.

The second abnormal set is a set formed by adjacent first abnormal sensors, the first abnormal sensors in the second abnormal set are taken as the second abnormal sensors for distinguishing the first abnormal set from the first abnormal set, and the third abnormal sensor is the second abnormal sensor with the largest vibration information.

In practical application, since the vibration information of the rotating structure may affect the rotating structure connected to the adjacent strut under the condition of damage, the vibration information of the rotating structure connected to the adjacent strut may also be abnormally increased, so that the vibration information of the rotating structure connected to the adjacent strut also becomes abnormal, when a plurality of adjacent second abnormal sensors are abnormal, it cannot be determined which second abnormal sensor is actually abnormal, and which second abnormal sensor is affected to become abnormal, so that after the plurality of adjacent second abnormal sensors are acquired, the second abnormal sensors are further distinguished.

Since the vibration information of the third abnormality sensor is the largest, it is likely to be the vibration information of another rotating structure affected by the damage of the rotating structure corresponding to the third abnormality sensor, and therefore the present embodiment uses the second abnormality sensor having the largest vibration information as the third abnormality sensor for the subsequent processing.

S4, obtaining connection paths of the second abnormal sensor and the third abnormal sensor in the second abnormal set, obtaining vibration attenuation coefficients of the corresponding connection paths according to entity attributes of the connection paths, and carrying out attenuation processing on vibration information of the third abnormal sensor to obtain vibration attenuation values.

The physical attribute of the connection path refers to various information of the supporting rod of the conductive folding frame, such as length, diameter, material, and the like. The vibration attenuation coefficient refers to the ratio of the value of the attenuation of the vibration information in the support rod of the conductive folding frame from the vibration source point to the target point to the vibration information, and the vibration attenuation value refers to the value of the corresponding rotating structure after the vibration information is attenuated in the support rod of the conductive folding frame.

In practical application, in order to distinguish whether the vibration information of the second abnormal sensor is the vibration information of the abnormal sensor or the vibration information affected to be the abnormal vibration information, whether the vibration information of the third abnormal sensor affects the vibration information of other sensors after being attenuated in the supporting rod of the conductive folding frame can be determined through attenuation of the vibration information.

Specifically, the vibration damping coefficient may be obtained through steps S41 to S43 described below, and the vibration damping value may be obtained through steps S44 to S45 described below.

S41, acquiring first position information of all vibration sensors, determining preset connection paths corresponding to two adjacent vibration sensors, and generating a preset path corresponding table according to the two first position information of the two adjacent vibration sensors and the preset connection paths.

The first position information refers to position points corresponding to all the sensors when all the sensors are normal in an initial state; the preset connection path refers to the connection path of two adjacent vibration sensors in the initial state; the preset path correspondence table is composed of the corresponding position points of each sensor and the corresponding preset connection paths in the initial state, for example, if the position points of each sensor are 001, 002, 003, 004 and 005 respectively, the connection paths of the 001 position point and the 002 position point are the corresponding preset connection paths.

In practical application, the corresponding position points of each vibration sensor in the initial state and the connection paths of each adjacent vibration sensor can be acquired first, and the corresponding preset path corresponding table is generated according to the position points and the connection paths of each vibration sensor, so that the preset connection paths corresponding to the position points can be obtained according to the preset corresponding table.

S42, acquiring second position information and third position information of the second abnormal sensor and the third abnormal sensor, traversing all preset connection paths in a preset path corresponding table, and determining abnormal connection paths corresponding to the second position information and the third position information.

The second position information refers to a position point corresponding to the second abnormal sensor, the third position information refers to a position point corresponding to the third abnormal sensor, and the abnormal connection path refers to a connection path between the second position information and the third position information.

For example, if it is determined that the position points corresponding to the adjacent first abnormal sensors are 002 and 003, in the above-described step, the present embodiment has set the adjacent first abnormal sensor as the second abnormal sensor and the second abnormal sensor having the largest vibration information as the third abnormal sensor, and if 002 is the position point corresponding to the second abnormal sensor and 003 is the position point corresponding to the third abnormal sensor, the abnormal connection path is the connection path between 002 and 003 positions.

S43, obtaining entity attributes of the abnormal connection paths, and obtaining vibration attenuation coefficients of the corresponding abnormal connection paths according to the entity attributes.

In practical application, the vibration information is attenuated by the struts of the conductive folding frame, and the physical properties such as the length, the diameter and the material of each strut of the conductive folding frame may be different, so the vibration attenuation coefficient of each strut may also be different, and therefore, the vibration attenuation coefficient of each strut needs to be calculated according to the physical properties corresponding to different connection paths.

In some embodiments, the vibration damping coefficient may be obtained through steps S431 to S434, specifically as follows:

s431, acquiring the current length information, the current diameter information and the current material information in the entity attribute.

The current length information refers to the current length of the support rod of the conductive folding frame, the current diameter information refers to the current diameter of the support of the conductive folding frame, and the current material information refers to the material information of the support of the conductive folding frame.

S432, acquiring a reference attenuation coefficient, reference length information and reference diameter information corresponding to the current material information.

Different material information can have different densities, so that different basic transmission efficiency can be realized in the vibration transmission process. When the reference attenuation coefficient is tested, the invention selects the entity of the corresponding material information corresponding to the specification of the reference length information and the reference diameter information to obtain the tested entity.

The method and the device can carry out attenuation test of vibration information on the tested entity, and further obtain a reference attenuation coefficient corresponding to the reference length information and the reference diameter information of each material information.

The reference damping coefficient may be calculated, for example, by setting the vibration information of the starting point of the vibration generated by the tested entity to 10, the vibration information of the end point of the vibration received by the tested entity to 9, the total damping of the starting point to the target point being 1, the ratio of 1 to 10 being 0.1, and the reference damping coefficient being 0.1; the reference length information may refer to the length of a previously set strut (tested entity) related to the reference attenuation coefficient, and the reference diameter information refers to the diameter of a previously set strut (tested entity) related to the reference attenuation coefficient.

S433, comparing the current length information with the reference length information to obtain a length deviation coefficient, and comparing the current diameter information with the reference diameter information to obtain a diameter deviation coefficient.

In practical application, the length and diameter of the strut may come in and go out with the reference length information and the reference diameter information, so that the length offset coefficient is obtained by comparing the current length information with the reference length information, and the diameter offset coefficient is obtained by comparing the current diameter information with the reference diameter information.

S434, calculating based on the length deviation coefficient, the diameter deviation coefficient and the reference attenuation coefficient to generate a vibration attenuation coefficient;

the vibration damping coefficient is calculated by the following equation,

As can be seen from the above formula, the current length information l ₁ is proportional to the vibration damping coefficient C, and the larger the current length information l ₁ is, the larger the vibration damping coefficient C is. In the sense that when the current length information l ₁ is equal to or greater than the predetermined value, the more energy is consumed for vibration, the more serious the vibration is damped, and the greater the corresponding vibration damping coefficient C is.

The current diameter information r ₁ is inversely related to the vibration damping coefficient C, and the larger the current diameter information r ₁ is, the smaller the vibration damping coefficient C is. Meaning that the greater the current diameter information r ₁, the less resistance to vibration information, the weaker the degree of vibration damping, and the smaller the corresponding vibration damping coefficient C. The reference attenuation coefficient J and the reference length information l ₂ in this embodiment are set corresponding to the reference diameter information r ₂. By the method, the vibration attenuation coefficients corresponding to different connecting paths can be obtained, and the vibration attenuation coefficients of the vibration information in different connecting paths can be better obtained.

S44, vibration information of the third abnormal sensor is obtained, and a vibration change value is obtained according to the product of the vibration information and the vibration attenuation coefficient.

The vibration change value refers to a value of vibration information which is changed after being attenuated in the support rod of the conductive folding frame, and the vibration change value can be obtained according to the product of the vibration information and the vibration attenuation coefficient.

S45, carrying out difference value calculation on the vibration information of the third abnormal sensor and the vibration change value to obtain a vibration attenuation value;

the vibration attenuation value is calculated by the following equation,

As can be seen from the above equation, the vibration attenuation coefficient C and the vibration attenuation value D ₁ are inversely related, and a larger vibration attenuation coefficient C indicates a larger vibration information attenuation, and a smaller vibration attenuation value D ₁ to which the corresponding vibration information is attenuated.

After the vibration attenuation value of the vibration information attenuated in the supporting rod can be obtained through the method, the target detection position point can be obtained through the step S5 and the step S6, and the method specifically comprises the following steps:

And S5, if the vibration attenuation value is larger than the vibration information of the second abnormal sensor, correcting the second abnormal sensor to be a normal sensor.

It will be appreciated that if the vibration attenuation value is greater than the vibration information of the second anomaly sensor, it is indicated that the vibration information anomaly of the second anomaly sensor is not caused by its corresponding abnormal rotational structure, but is caused by the influence of the vibration information of the third anomaly sensor, and the second anomaly sensor may be corrected to be a normal sensor. By correcting the second abnormal sensor into the normal sensor through the method, the damaged rotating structure and the undamaged rotating structure can be effectively distinguished, subsequent maintenance work is facilitated, the workload of staff is reduced, and time cost and labor cost are saved.

And S6, if the vibration attenuation value is smaller than or equal to the vibration information of the second abnormal sensor, taking the position point corresponding to the second abnormal sensor as a target detection position point.

It will be understood that if the vibration attenuation value is smaller than the vibration information of the second anomaly sensor, it is indicated that the vibration information of the second anomaly sensor is not affected by the third anomaly sensor and is in an anomaly state, and the rotating structure corresponding to the second anomaly sensor is likely to be damaged, and at this time, the position point corresponding to the second anomaly sensor may be regarded as the target detection position point.

In some special cases, the situation that the vibration information of the second abnormal sensor is larger than the vibration attenuation value due to superposition of the vibration information may occur, but the rotating structure corresponding to the second abnormal sensor is not damaged, and the situation is low in occurrence probability, so that the scheme defaults to be absent.

In S11 (the number of anomalies of the first anomaly sensor is obtained, if the number of anomalies is less than or equal to 3, a target detection position point is determined according to the first anomaly sensor, and early warning information is generated according to the target detection position point and sent to a control terminal for display), since multiple situations occur when the number of anomalies is 3, the present solution discusses multiple situations through the following steps S61 to S62, respectively.

And S61, if the number of the anomalies is equal to 3, taking the second anomaly sensor with the smallest vibration information in the second anomaly set as a fourth anomaly sensor.

In the present embodiment, in order to distinguish between multiple cases when the number of anomalies is 3, the vibration sensors in the second anomaly set are respectively named as a third anomaly sensor, a second anomaly sensor, and a fourth anomaly sensor from large to small according to the vibration information.

S62, generating a position relation according to the second position information of the second abnormal sensor, the third position information of the third abnormal sensor and the fourth position information of the fourth abnormal sensor, and determining a target detection position point according to the position relation, the second abnormal sensor, the third abnormal sensor and the fourth abnormal sensor.

The fourth position information refers to a position point corresponding to the fourth abnormal sensor, and the position relation refers to a relation among the second position information, the third position information and the fourth position information.

In some embodiments, the above target detection position point may be acquired by the following steps S621 to S629:

S621, if the positional relationship is that the third positional information is located between the second positional information and the fourth positional information, determining a first abnormal connection path corresponding to the second positional information and the third positional information, and a second abnormal connection path corresponding to the third positional information and the fourth positional information.

The first abnormal connection path is a connection path of the second position information and the third position information, and the second abnormal connection path is a connection path of the third position information and the fourth position information.

It will be appreciated that if the third position information is located between the second position information and the third position information, it is explained that the sensor with the largest vibration information is located between the other two sensors, and since damage to the rotating structure may affect the vibration information of the rotating structure adjacent thereto, it is likely that abnormality occurs in the second abnormal sensor and the fourth abnormal sensor due to damage to the rotating structure corresponding to the third abnormal sensor in this case.

Based on this, the connection path adjacent to the third abnormal sensor can be confirmed by the first abnormal connection path and the second abnormal connection path, respectively, and then the subsequent operation can be performed.

S622, obtaining a first vibration attenuation coefficient of the corresponding first abnormal connection path according to the entity attribute of the first abnormal connection path, and performing attenuation processing on the vibration information of the third abnormal sensor to obtain a first vibration attenuation value.

The first vibration attenuation coefficient refers to a ratio of a value of vibration information of the third abnormal sensor attenuated in the strut corresponding to the first abnormal connection path to vibration information of the third abnormal sensor, and the first vibration attenuation value refers to a value of vibration information of the third abnormal sensor attenuated and then at the second position information.

S623, obtaining a second vibration attenuation coefficient of the corresponding second abnormal connection path according to the entity attribute of the second abnormal connection path, and performing attenuation processing on the vibration information of the third abnormal sensor to obtain a second vibration attenuation value.

The second vibration attenuation coefficient refers to a ratio of a value of vibration information of the third abnormal sensor attenuated in the strut corresponding to the second abnormal connection path to vibration information of the third abnormal sensor, and the second vibration attenuation value refers to a value of the vibration information of the third abnormal sensor attenuated and then subjected to fourth position information.

After the vibration attenuation values of the vibration information of the third abnormal sensor at the adjacent different position points can be obtained through the method, the target detection position point can be determined through the vibration attenuation values.

S624, if the first vibration attenuation value is less than or equal to the vibration information of the second anomaly sensor or the second vibration attenuation value is less than or equal to the vibration information of the fourth anomaly sensor, the position point corresponding to the second anomaly sensor or the fourth anomaly sensor is taken as the target detection position point.

In practical application, if the damage of the rotating structure corresponding to the third abnormal sensor affects the abnormal vibration information of the other two sensors, the vibration information of the second abnormal sensor is smaller than the first vibration attenuation value, and the vibration information of the fourth abnormal sensor is smaller than the second vibration attenuation value.

The fact that the vibration information of the second abnormal sensor is greater than the first vibration attenuation value or the vibration information of the fourth abnormal sensor is greater than the second vibration attenuation value indicates that the vibration information of the second abnormal sensor or the vibration information of the fourth abnormal sensor is abnormal not due to damage to the rotating structure corresponding to the third abnormal sensor but due to damage to the rotating structure corresponding to the third abnormal sensor, and at this time, a position point corresponding to the second normal sensor or the fourth abnormal sensor can be used as a target detection position point.

In some extreme cases, a phenomenon may occur in which the vibration information of the second abnormal sensor is smaller than that of the third abnormal sensor, or the vibration information of the fourth abnormal sensor is smaller than that of the third abnormal sensor, but the rotating structure corresponding to the second abnormal sensor or the fourth abnormal sensor is damaged at this time, and the possibility of occurrence of such a situation is small, so that the scheme defaults to the absence thereof.

And S625, if the position relation is that the second position information is located between the third position information and the fourth position information, taking the position point corresponding to the second abnormal sensor as a target detection position point.

It will be appreciated that if the second position information is located between the third position information and the fourth position information, it is explained that the second sensor of the vibration information is located between the other two sensors, and because the damage of the rotating structure hardly affects the vibration information of the rotating structure not adjacent thereto, the vibration information of the fourth abnormal sensor is likely to be affected by the vibration information of the second abnormal sensor adjacent thereto, but not by the vibration information of the third abnormal sensor.

In the present embodiment, the vibration information abnormality of the third abnormality sensor and the second abnormality sensor in the above case is due to the damage of the rotating structure by default without taking the extreme case into consideration, and therefore, the position point corresponding to the second abnormality sensor may be set as the target detection position point.

S626, a third abnormal connection path corresponding to the second position information and the fourth position information is obtained and determined, a third vibration attenuation coefficient of the corresponding third abnormal connection path is obtained according to the entity attribute of the third abnormal connection path, and the vibration information of the second abnormal sensor is subjected to attenuation processing to obtain a third vibration attenuation value.

The third abnormal connection path refers to a connection path of the second position information and the fourth position information, the third vibration attenuation coefficient refers to a ratio of a value of vibration information of the second abnormal sensor attenuated in the strut corresponding to the third abnormal connection path to the vibration information of the second abnormal sensor, and the third vibration attenuation value refers to a value of the vibration information of the second abnormal sensor attenuated and then subjected to the fourth position information.

It is known from the above method that the rotation structure corresponding to the third abnormal sensor and the second abnormal sensor is in a damaged state, but it cannot be confirmed whether the rotation structure corresponding to the fourth abnormal sensor is in a damaged state, so it is necessary to obtain a third vibration attenuation value by attenuating vibration information of the second abnormal sensor, and then compare the third vibration attenuation value with vibration information of the fourth abnormal sensor to know whether the vibration information of the fourth abnormal sensor is abnormal due to the damage of the rotation structure.

And S627, if the third vibration attenuation value is smaller than or equal to the vibration information of the fourth abnormal sensor, taking the position point corresponding to the fourth abnormal sensor as a target detection position point.

In practical application, if the third vibration attenuation value is smaller than the vibration information of the fourth anomaly sensor, it is indicated that the vibration information of the fourth anomaly sensor is not abnormal due to the influence of the vibration information of the second anomaly sensor, but is caused by the damage of the rotating structure, and at this time, the position point corresponding to the fourth anomaly sensor may be regarded as the target detection position point.

S628, if the position relation is that the fourth position information is located between the third position information and the second position, the position point corresponding to the fourth abnormal sensor is taken as the position point to be detected.

S629, determining the position points corresponding to the second and third anomaly sensors as target detection position points.

It will be appreciated that if the fourth position information is located between the third position information and the second position information, it is explained that the sensor with the smallest vibration information is located between the other two sensors, and since the vibration information of the fourth abnormal sensor is the smallest, it has little influence on the vibration information of the third abnormal sensor and the second abnormal sensor, and therefore it is likely that the vibration information of the third abnormal sensor and the vibration information of the fourth abnormal sensor affect the vibration information of the fourth abnormal sensor.

In this case, the rotation structure corresponding to the third abnormality sensor and the second abnormality sensor in the above case is defaulted to be in a damaged state without considering an extreme case, and therefore, the position point corresponding to the second abnormality sensor and the third abnormality sensor can be set as the target detection position point.

Since the vibration information of the fourth anomaly sensor cannot determine whether the rotation structure is abnormal due to damage or is affected by the vibration information of the third anomaly sensor and the second anomaly sensor, the position point corresponding to the fourth anomaly sensor is used as the position point to be detected, and the position point to be detected is the position point where the damage information is not determined.

It should be noted that, the target detection location point in the present solution is a damaged location point that can be referred to by a worker, and in some cases, other location points may be damaged.

The method further comprises the steps of:

and controlling a display device to display the label corresponding to the position point to be detected.

The display device may be a computer or other display devices. The position of the position point to be detected is the position of the rotating structure, so that the marks of the position point to be detected can be set as 001, 002, 003, 004 and 005 correspondingly. The target detection position point is obtained through the method, the specific position of the damage of the rotating structure can be better determined, the subsequent maintenance work is convenient, the whole process does not need to waste too much time, and the efficiency is greatly improved.
