Description

Technical Field

[0001] This application belongs to the field of generator technology, and more specifically, relates to a gap measurement method, device and electronic equipment. Background Technology

[0002] Currently, during the replacement or installation of the inner stator in a generator, the vibration damping structure between the inner and outer stators contains numerous spring plates. If there are any deviations in the installation of the inner stator, such as tilting or offset, it will affect the normal operation of the generator. Therefore, on-site measurement and installation are often adopted, with professional personnel using measuring blocks to measure the gap between the spring plates and the inner stator.

[0003] However, this method is extremely time-consuming and involves a complicated and cumbersome process, as well as heavy workload, increasing the labor intensity of the staff. Moreover, during the measurement process, the inner stator needs to rely on jacks for temporary support for a long time, which makes it extremely easy for serious accidents such as tilting or falling of the inner stator due to sudden situations such as jack failure or displacement of the support point, posing a great safety risk.

[0054] It is understandable that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here.

[0055] This application provides a gap measurement method for measuring the gap between multiple spring plates installed on the outer stator of a generator and the inner stator. The method includes: acquiring the spatial coordinates of each corner vertex of each spring plate installed on the outer stator; obtaining gap measurement data between the target spring plate and the inner stator in each orientation of the outer stator, wherein the outer stator is divided into multiple orientations based on spatial position characteristics; fitting a contact plane between the target spring plate and the inner stator based on the spatial coordinates of each corner vertex of the target spring plate and the gap measurement data between the target spring plate and the inner stator; and feeding back gap measurement data between the corner vertices of other spring plates and the inner stator based on the distance from each corner vertex of other spring plates in each orientation to the contact plane, wherein the other spring plates are spring plates other than the target spring plate.

[0056] This application's method, by selecting key target spring plates (e.g., the first and last spring plates in each orientation) and measuring the gap between them and the inner stator, combines this data with the spatial coordinates of each corner vertex of all spring plates. A mathematical fitting method is then used to fit the contact plane between the target spring plate and the inner stator. Based on the distances from each corner vertex of the other spring plates in each orientation to the contact plane, the method displays and provides feedback on the gap measurements between other spring plates and the inner stator. Since it eliminates the need to directly measure the gaps between all spring plates and the inner stator, the number of gaps that actually need to be measured is reduced, thus simplifying the measurement process, saving significant measurement time, and avoiding the tedious and time-consuming nature of extensive manual measurements.

[0057] Furthermore, in traditional measurement methods, due to the long measurement time, the inner stator needs to rely on jacks for temporary support for an extended period, posing a risk of serious accidents such as tilting or falling of the inner stator due to jack failure or displacement of the support point. This application's example reduces the time the inner stator relies on jacks for temporary support by shortening the gap measurement time, thereby effectively reducing the risk of accidents such as tilting or falling of the inner stator and improving safety during the installation or replacement of the inner stator.

[0072] Currently, during the replacement or installation of the inner stator in a generator, the vibration damping structure between the inner and outer stators contains numerous spring plates. If there are any deviations in the installation of the inner stator, such as tilting or offset, it will affect the normal operation of the generator. Therefore, on-site measurement and installation are often adopted, with professional personnel using measuring blocks to measure the gap between the spring plates and the inner stator.

[0073] However, this method is extremely time-consuming and involves a complicated and cumbersome process, as well as heavy workload, increasing the labor intensity of the staff. Moreover, during the measurement process, the inner stator needs to rely on jacks for temporary support for a long time, which makes it extremely easy for serious accidents such as tilting or falling of the inner stator due to sudden situations such as jack failure or displacement of the support point, posing a great safety risk.

[0074] To address the aforementioned technical problems, this application provides an example of a gap measurement method, please refer to... Figure 1 As shown, Figure 1 A schematic flowchart of a gap measurement method provided in this application is shown. This is an example, not a limitation. The method can be applied to or operated in electronic devices such as detection terminals for measuring the gap between multiple spring plates mounted on the outer stator of a generator and the inner stator. The method includes:

[0075] S101, collect the spatial position coordinates of each corner vertex of each spring plate installed on the outer stator.

[0076] S102, acquire the gap measurement data between the target spring plate and the inner stator in each position of the outer stator, wherein the outer stator is divided into multiple positions according to its spatial position characteristics.

[0077] S103. Based on the spatial coordinates of each corner vertex of the target spring plate and the gap measurement data between the target spring plate and the inner stator, fit the contact plane between the target spring plate and the inner stator.

[0078] S104, based on the distance from each corner vertex of the other spring plates in each orientation to the contact plane, feed back the gap measurement data between each corner vertex of the other spring plates and the inner stator, wherein the other spring plates are spring plates other than the target spring plate.

[0079] Optionally, the generator in this application example is an inner and outer stator structure generator. The inner stator is located in the center of the generator, and the outer stator surrounds the inner stator. There is a certain space between the inner stator and the outer stator. In this space, vibration damping structures such as spring plates can be arranged to reduce the vibration and noise generated during the operation of the generator and improve the stability and reliability of the generator.

[0080] The following is an explanation of the implementation method of this gap measurement method, as well as an explanation of the corresponding technical effects:

[0081] In some alternative examples, a high-precision laser device, such as a laser tracker, can be placed inside the outer stator of the generator. The laser tracker can emit a laser beam and measure information such as distance and angle by receiving the reflected laser beam.

[0082] For each spring plate, a specially designed target (e.g., a target ball with high reflectivity) is installed at each corner vertex of each spring plate. Then, a laser tracker illuminates these targets with an emitted laser beam and calculates the spatial coordinates of the target based on principles such as the time difference between the emitted and received laser beams. This allows the laser tracker to obtain the spatial coordinates of each corner vertex of each spring plate (e.g., coordinate values ​​in the x, y, and z directions).

[0083] In one alternative example, the corner vertices of all spring plates can be measured and recorded sequentially according to a predetermined acquisition order to ensure that the spatial coordinates of the corner vertices of all spring plates can be obtained.

[0084] Optionally, in some examples, the outer stator can be pre-divided into multiple orientations based on its spatial position characteristics, such as up, down, left, and right. Then, the target spring plate in each orientation is determined; for example, the first and last spring plates in each orientation can be selected as the target spring plates.

[0085] Specifically, the gap measurement data between the target spring plate and the inner stator in each orientation is obtained manually using a suitable measuring tool, such as a feeler gauge. For example, the feeler gauge is inserted into the gap between the target spring plate and the inner stator, the size of the gap is determined according to the thickness of the feeler gauge, and the gap measurement data between each target spring plate and the inner stator is recorded in detail to a database or storage space. Thus, in this application example, the gap measurement data between the target spring plate and the inner stator in each orientation can be obtained from the database or storage space.

[0086] Then, the spatial coordinates of each corner vertex of the target spring plate and the corresponding gap measurement data obtained earlier can be used with mathematical fitting algorithms, such as the least squares method, to find an optimal plane equation, such as Ax+By+Cz+D=0, by calculating the sum of the squares of the distances from each corner vertex of the target spring plate to the fitting plane (contact plane). This ensures that the contact plane can represent the contact between the target spring plate and the inner stator as accurately as possible. By calculating and adjusting the parameters A, B, C, and D of the plane equation, the fitted contact plane can be obtained.

[0087] It should be understood that the basic idea of ​​the least squares method is to find an optimal plane equation by minimizing the objective function (i.e., the sum of the squares of the distances from each corner vertex of the target spring plate to the fitting plane (contact plane)).

[0088] For each orientation of the spring plates other than the target spring plate, the spatial coordinates of the vertices of the other spring plates are known. Let the spatial coordinates of point A be x0, y0, z0, and the plane equation be A. x +B y +C z If +D=0, then the formula for the distance from a point to a plane is:

[0089] Substitute the spatial coordinates of each corner vertex of the other spring plates into the above formula for the distance from a point to a plane to calculate the distance from each corner vertex of the other spring plates to the fitted contact plane. This distance is then displayed on the screen as the gap measurement data between each corner vertex of the other spring plates and the inner stator. In other words, it is the gap measurement data between the other spring plates and the inner stator. Furthermore, if shims are set on the spring plates, it can be understood as the gap measurement data between the shims of the other spring plates and the inner stator (e.g., in mm).

[0090] This application's method, by selecting key target spring plates (e.g., the first and last spring plates in each orientation) and measuring the gap between them and the inner stator, combines this data with the spatial coordinates of each corner vertex of all spring plates. A mathematical fitting method is then used to fit the contact plane between the target spring plate and the inner stator. Based on the distances from each corner vertex of the other spring plates in each orientation to the contact plane, the method displays and provides feedback on the gap measurements between other spring plates and the inner stator. Since it eliminates the need to directly measure the gaps between all spring plates and the inner stator, the number of gaps that actually need to be measured is reduced, thus simplifying the measurement process, saving significant measurement time, and avoiding the tedious and time-consuming nature of extensive manual measurements.

[0091] Furthermore, in traditional measurement methods, due to the long measurement time, the inner stator needs to rely on jacks for temporary support for an extended period, posing a risk of serious accidents such as tilting or falling of the inner stator due to jack failure or displacement of the support point. This application's example reduces the time the inner stator relies on jacks for temporary support by shortening the gap measurement time, thereby effectively reducing the risk of accidents such as tilting or falling of the inner stator and improving safety during the installation or replacement of the inner stator.

[0092] The following analysis examines the optional implementation methods of several steps in the above gap measurement method, and the technical effects they produce in solving existing problems:

[0093] In one possible implementation, please refer to Figure 2 As shown, Figure 2 A schematic flowchart of an optional gap measurement method provided in this application is shown. S101, acquiring the spatial position coordinates of each corner vertex of each spring plate mounted on the outer stator, including:

[0094] S201 employs a laser tracker installed inside the outer stator to emit laser beams to targets at each corner vertex of each spring plate; wherein, at least one target mount is fixedly installed at each corner vertex, and a target is mounted on the target mount.

[0095] S202 uses a laser tracker to receive the reflected beams from the target at each corner vertex.

[0096] S203, determine the time interval between the laser tracker emitting the laser beam and receiving the reflected beam.

[0097] S204, determine the spatial coordinates of each corner vertex relative to the laser tracker based on the time interval.

[0098] Optionally, in one example, a laser tracker can be pre-installed inside the generator's external stator. The laser tracker emits and receives reflected laser beams and performs precise measurements based on the propagation characteristics of the laser.

[0099] In some examples, at least one target can be fixedly set at each corner vertex of each spring plate in advance, and a target (e.g., a target ball) can be installed on the target. The target is reflective and provides a target point for the measurement of the laser tracker. The position of the target directly corresponds to the position of each corner vertex of the spring plate. By reflecting the laser beam emitted by the laser tracker, the position information of the spring plate can be accurately reflected, ensuring the accuracy and stability of the measurement.

[0100] In one example, based on the principle of laser reflection, the laser tracker emits a laser beam to a target at each corner vertex of each spring plate. The target reflects the laser beam back to the laser tracker, which then receives the reflected beam. By emitting the laser beam and receiving the reflected beam, the laser tracker establishes a signal transmission path for measurement. The laser tracker records the time interval between emitting the laser beam and receiving the reflected beam, and can calculate the distance from the laser tracker to the target using the formula that distance equals velocity multiplied by time.

[0101] Since the speed of laser propagation in a vacuum is a known constant (approximately 299,792,458 meters per second, usually represented by the symbol c), the distance from the laser tracker to the target at each corner vertex can be calculated based on the measured time interval and the laser propagation speed. This determines the spatial coordinates of each corner vertex relative to the laser tracker (including coordinates in the x, y, and z directions).

[0102] Compared to traditional methods that involve complex and time-consuming measurements of spring plates, the above-described method, using a laser tracker and target measurement, can quickly obtain the spatial coordinates of each corner vertex of the spring plate. This reduces the time required to measure the spatial coordinates of each corner vertex, thus speeding up the entire measurement process and helping to shorten the time required for replacing or installing the inner stator. Furthermore, this measurement method is relatively automated; workers only need to perform simple operations such as installing the laser tracker and fixing the target holder, eliminating the need for extensive and tedious manual measurement and data recording. The laser tracker can automatically record and calculate measurement data, reducing the workload and complexity for workers and lowering their labor intensity.

[0103] Furthermore, by quickly obtaining the spatial coordinates of each corner vertex of the spring plate, the entire measurement process is shortened. During the replacement or installation of the inner stator, the reduced measurement time means less time the inner stator relies on jacks for temporary support, thereby lowering the risk of serious accidents such as tilting or falling of the inner stator due to sudden situations like jack failure or support point displacement, and improving operational safety.

[0104] In one possible implementation, the target spring plate includes: a first spring plate and a last spring plate. Please refer to [reference needed]. Figure 3 As shown, Figure 3 A schematic flowchart of an optional gap measurement method provided in this application is shown. S102, acquiring gap measurement data between the target spring plate and the inner stator in each orientation of the outer stator, includes:

[0105] S301, obtain the first measuring gap between the first spring plate and the inner stator in each position of the outer stator, and the second measuring gap between the last spring plate and the inner stator in each position of the outer stator.

[0106] S302, based on the first measurement gap and the second measurement gap, determine the gap measurement data between the target spring plate and the inner stator in each orientation of the outer stator.

[0107] By selecting the spring plates at both ends (first and last) of each orientation as the target spring plates, the relative positional relationship between the spring plates and the inner stator in that orientation can be better reflected when calculating the gap between other spring plates and the inner stator using fitting or other methods. In some examples, the first and last spring plates in each orientation of the outer stator can be used as the target spring plates.

[0108] In some examples, the first and last spring plates in each orientation can be pre-marked by the workers involved in installing or replacing the inner stator. Therefore, all that is needed is for the workers to accurately identify and mark the specific locations of the first and last spring plates in each orientation (e.g., setting targets at each corner vertex of the first and last spring plates in each orientation, etc.).

[0109] Specifically, the measuring equipment can use appropriate measuring tools, such as feeler gauges or dial indicators, to measure the gap between the first spring plate and the inner stator in each position. The measuring tool is accurately aligned with the gap between the first spring plate and the inner stator, and the gap value displayed on the measuring tool is read to obtain the first measured gap. Alternatively, workers can use measuring tools, such as feeler gauges or dial indicators, to measure the gap between the first spring plate and the inner stator in each position.

[0110] It should be understood that during the measurement process, it is necessary to ensure the correct use of measuring tools to guarantee the accuracy of the measurement data. For example, when using feeler gauges, a feeler gauge piece of appropriate thickness should be selected to ensure that the feeler gauge piece can be inserted tightly into the gap without causing excessive deformation.

[0111] Similarly, using the same or similar measuring tools described above, the gap between the last spring plate and the inner stator in each orientation is measured. Following the same operating procedure as for measuring the first gap, the measuring tool is placed between the last spring plate and the inner stator, and the gap value displayed by the measuring tool is read to obtain the second gap measurement.

[0112] Subsequently, based on the obtained first and second measurement gaps, simple records and organization were performed, and these two measurements were used as the gap measurement data between the target spring plate and the inner stator at that azimuth. It should be understood that the first and second measurement gaps reflect the actual gap between the two spring plates and the inner stator at that azimuth, and can more accurately estimate the gaps between other spring plates and the inner stator, ensuring the validity of the measurement data and the reliability of the measurement results.

[0113] Compared to traditional methods that measure the gap of each spring plate individually, this application's example measures the gap between the first and last spring plates in each orientation and the inner stator, instead of measuring the gap of all spring plates. This significantly reduces the time required to measure the gap data, thus accelerating the measurement process and consequently shortening the time required to install or replace the stator. Furthermore, workers no longer need to perform tedious gap measurements on each spring plate, reducing their workload and increasing efficiency. In addition, the reduced time for measuring gap data means less time the inner stator is temporarily supported by jacks. This shorter temporary support time reduces the likelihood of serious accidents such as the inner stator tilting or falling due to jack failure, support point displacement, or other factors.

[0114] In one possible implementation, please refer to Figure 4 As shown, Figure 4 A schematic flowchart of an optional gap measurement method provided in this application is shown. S103, based on the spatial coordinates of each corner vertex of the target spring plate and the gap measurement data between the target spring plate and the inner stator, a contact plane between the target spring plate and the inner stator is fitted, including:

[0115] S401, based on the principle of least squares, iteratively calculates the spatial coordinates of each corner vertex of the target spring plate and the gap measurement data between the target spring plate and the inner stator until the best fitting plane parameter value that minimizes the sum of the squares of the distances between each corner vertex of the target spring plate and the spatial plane is obtained.

[0116] S402, Based on the best-fit plane parameter values ​​and the general equation of the space plane, determine the contact plane equation between the target spring plate and the inner stator, where the contact plane equation is used to characterize the contact plane between the target spring plate and the inner stator.

[0117] It should be understood that the least squares method is a mathematical optimization method that finds the optimal function match for data by minimizing the sum of squared errors. In the gap measurement scenario provided in this application example, the spatial position coordinates (including x, y, and z coordinates) of each corner vertex of the target spring plate (i.e., the first and last spring plates in each orientation) and the gap measurement data between the target spring plate and the inner stator are iteratively calculated, and the spatial plane equation (generally A) is continuously adjusted based on the least squares method. x +B y +C z The parameters A, B, C, and D in (+D=0).

[0118] Then, for each corner vertex of each set of target spring plates, the spatial coordinates x i ,y i ,z i Calculate the distance from the vertex of the corner to the current plane (A). x +B y +C z Distance +D=0) Then calculate the sum of the squares of the distances from all corner vertices to the plane. (n is the total number of corner vertices for each target spring plate). By continuously adjusting parameters A, B, C, and D, S is gradually reduced, and this calculation continues until a certain convergence condition is met. For example, the change in the sum of squared distances S is less than a preset minimum value, or the preset maximum number of iterations is reached. The parameter values ​​obtained at this point are the best-fit plane parameter values ​​that minimize the sum of squared distances between each corner vertex of the target spring plate and the spatial plane.

[0119] After obtaining the parameter values ​​of the best-fit plane, substitute these parameter values ​​into the general equation A of the spatial plane. x +B y +C z In +D=0, the contact plane equation between the target spring plate and the inner stator is determined. This contact plane equation describes the position and orientation of the contact plane between the target spring plate (specifically the gasket of the target spring plate) and the inner stator in space, providing a reference plane for subsequent calculation of the gap between other spring plates and the inner stator.

[0120] By using the least squares method for plane fitting, and fully utilizing the spatial coordinates of the target spring plate's vertices and gap measurement data, a plane that best represents the actual contact situation can be found. Compared to some simple estimation or assumption methods, data-based fitting can more accurately reflect the contact relationship between the target spring plate and the inner stator, thereby improving the accuracy of gap measurements between other spring plates and the inner stator. Subsequently, the gaps from each corner vertex of other spring plates to the inner stator are calculated based on the fitted contact plane. Therefore, a more accurate fitted plane means more accurate gap measurement results, which helps to more accurately match operations such as the pads used in processing spring plates.

[0121] Compared to traditional methods that require complex measurements and analyses of each spring plate to determine its relationship with the inner stator, this method, by fitting a target spring plate (representative) to the contact plane between the inner stator and the inner stator, can quickly calculate the gaps between other spring plates and the inner stator, significantly reducing the workload of measurement and analysis. Furthermore, shortening the measurement time reduces the temporary support time for the inner stator, lowering the risk of serious accidents such as tilting or falling due to sudden situations like jack failure or support point displacement, thus improving safety during inner stator replacement or installation.

[0122] Since it is not necessary to perform complex measurements and analyses on each spring plate, staff only need to complete basic tasks such as measuring the gap of the target spring plate and collecting the vertex coordinates of all spring plates. Subsequent plane fitting and other gap measurements between the spring plates and the inner stator can be completed automatically using mathematical methods and calculation tools.

[0123] In one possible implementation, please refer to Figure 5 As shown, Figure 5 A schematic flowchart of an optional gap measurement method provided in this application is shown. S104, based on the distance from each corner vertex of the other spring plates in each orientation to the contact plane, feedback is provided on the gap measurement data between the corresponding corner vertices of the other spring plates and the inner stator, including:

[0124] S501 uses the mathematical formula for the distance from a point to a plane to calculate the distance from each corner vertex of the other spring plates in each direction to the contact plane.

[0125] S502 displays the distance from each corner vertex of the other spring plates to the contact plane as the corresponding gap measurement data between each corner vertex of the other spring plates and the inner stator on the display interface.

[0126] In some examples, in a spatial rectangular coordinate system, if the spatial coordinates of a point are x0, y0, z0, and the equation of the plane is A... x +B y +C zIf +D=0, then the formula for the distance from a point to a plane is:

[0127] In this measurement method, the contact plane equation between the target spring plate and the inner stator has been fitted through the previous steps, thus determining the parameter values ​​of parameters A, B, C, and D in the plane equation. For each orientation of the other spring plates besides the target spring plate (the first spring plate and the last spring plate), the spatial coordinates of each corner vertex of the other spring plates are known. The spatial coordinates (x0, y0, z0) of each corner vertex of the spring plate are substituted into the point-to-plane distance formula, and the distance d from each corner vertex to the contact plane is calculated in turn. The calculated distances d from each corner vertex of the other spring plates to the contact plane are directly used as the gap measurement data between these corner vertices and the inner stator.

[0128] It should be noted that the above example is based on the premise that the fitted contact plane can characterize the contact state between the target spring plate and the inner stator. It is assumed that the distance from each corner vertex of the other spring plates to the contact plane is approximately equal to the gap between each corner vertex and the inner stator. Thus, the gap measurement data between the other spring plates and the inner stator can be quickly determined, and the gap measurement process can be completed.

[0129] The gap between each corner vertex of other spring plates and the inner stator is calculated using the point-to-plane distance formula, avoiding the tedious process of directly measuring the gap of each spring plate. Only the coordinates of each corner vertex of the existing spring plates and the fitted contact plane equation are needed to quickly determine the gap measurement data between other spring plates and the inner stator. This reduces the time and workload of measurement operations, improves measurement efficiency, and consequently reduces the time the inner stator relies on temporary jack support.

[0130] Since the contact plane is obtained by fitting the corner vertex coordinates of the target spring plate and the gap measurement data using the least squares method, it can reflect the actual contact between the target spring plate and the inner stator relatively well. Based on this fitted plane, the gap from each corner vertex of other spring plates to the inner stator can be calculated, resulting in more accurate gap measurement data that meets the accuracy requirements of actual operations.

[0131] In one possible implementation, the spatial position coordinates of each corner vertex of each spring plate mounted on the outer stator can be acquired using the following steps:

[0132] Obtain a predetermined acquisition sequence, wherein the predetermined acquisition sequence is at least one of the acquisition sequence arrangements that take any position of the outer stator as the starting point and switch positions according to different horizontal and vertical directions.

[0133] According to the predetermined acquisition sequence, the spatial position coordinates of each corner vertex of each spring plate in each direction are collected sequentially.

[0134] In some examples, the outer stator has been pre-divided into multiple orientations (such as up, down, left, and right) based on spatial characteristics. First, one orientation can be chosen as the starting point, for example, the up orientation. Then, various permutations and combinations of orientation switching in different horizontal and vertical directions are considered.

[0135] It should be understood that horizontal switching can be from left to right or from right to left, and vertical switching can be from top to bottom or from bottom to top. Various acquisition sequences can be obtained by combining these directional switching methods. One achievable acquisition sequence is: top (starting point) → left (horizontal switching) → bottom (vertical switching) → right (horizontal switching).

[0136] It should be understood that in this application example, staff may determine one or more collection sequences as the predetermined collection sequence based on actual circumstances (such as the convenience of measurement, equipment layout, etc.), and this application example is not limited to one or more predetermined collection sequences.

[0137] Once the predetermined acquisition sequence is determined, the spatial coordinates of each corner vertex of each spring plate are acquired. In one example, assuming the predetermined acquisition sequence is to first acquire the spatial coordinates of each corner vertex of the upper spring plate, for each upper spring plate, the spatial coordinates of each corner vertex of each spring plate are acquired sequentially using the method mentioned earlier (e.g., using a laser tracker installed inside the outer stator to measure the coordinates of the targets mounted on the target mounts at each corner vertex of the spring plate by emitting and receiving laser beams). After acquiring the spatial coordinates of each corner vertex of one spring plate, the laser tracker automatically moves to the next upper spring plate according to the travel path and continues acquisition until the spatial coordinates of each corner vertex of all upper spring plates have been acquired.

[0138] After completing the acquisition of the upper position, switch to the next position (e.g., left position) according to the predetermined acquisition order, and repeat the above operation to acquire the corner coordinates of all spring plates in that position. In this way, complete the acquisition of the spatial position coordinates of each corner vertex of the spring plates in each position until the spatial position coordinates of each corner vertex of the spring plates in all positions have been acquired.

[0139] By allowing users to select any location on the outer stator as the starting point and switch between different horizontal and vertical orientations in various combinations of acquisition sequences, the most suitable acquisition sequence can be selected based on factors such as the actual measurement environment and equipment layout, thereby improving measurement efficiency. For example, if the laser tracker is installed closer to a certain location on the outer stator, that location can be selected as the starting point to reduce the movement and adjustment of the laser tracker and improve measurement convenience.

[0140] Furthermore, by providing operational guidance for the measurement work through a predetermined acquisition sequence, problems such as confusion and repeated measurements that may occur during the acquisition process are avoided, thus optimizing the measurement process and reducing unnecessary time waste. For example, by sequentially acquiring the spatial position coordinates of each corner vertex of the spring plate in each direction according to the predetermined sequence, it can be ensured that each spring plate is accurately measured without omission or repeated measurement, thereby improving measurement accuracy and efficiency.

[0141] Furthermore, the optimized measurement process and improved measurement efficiency directly lead to a reduction in measurement time. Because the spatial coordinates of each corner vertex of the spring plate can be acquired more quickly and accurately, the time required for the entire measurement process is reduced, thereby reducing the time the inner stator relies on jacks for temporary support.

[0142] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
