Description

Technical Field

[0001] This invention belongs to the field of maintenance technology for astronomical equipment, and specifically relates to a method, system, and device for quickly locating faults in actuator auxiliary equipment. Background Technology

[0002] FAST (Five-hundred-meter Aperture Spherical radio Telescope), as a single-aperture radio telescope, collects signals from celestial objects for astronomical observation. The FAST telescope comprises multiple nodes. During operation, any change in the position of any node will affect the observation accuracy. The main factors affecting node position include the unwinding of the pull-down cable connected to the node, the removal of the anchor block, or actuator malfunction. The unwinding of the pull-down cable refers to the backspinning of the connection between the pull-down cable and the actuator and node, resulting in an increased distance between the actuator connection point and the cable net node. The actuator is the main driving device, and its health can be determined based on its returned operational data. If a particular actuator malfunctions severely, it may need to be replaced. When replacing the actuator, its internal parameters also need to be updated. The zero-point value setting in these parameters also affects the node position. This zero-point value is fixed. Based on the established parameters, the anchor blocks and pull cables can be considered auxiliary equipment of the actuator. Problems with these components can only be detected through on-site inspections. Therefore, to ensure the accuracy of observations, the inspection and maintenance of the pull cables and anchor blocks are crucial. Currently, FAST conducts 5300 hours of scientific observations annually, which is a considerable challenge for the active reflector system itself. Due to the large number and wide distribution of actuators, the poor accessibility of some actuator locations, and the complex terrain and numerous actuators at the FAST site, a single inspection takes a long time—up to 45 days. This makes it difficult to detect problems such as pull-out pull cable anchor blocks or pull cable retraction in a timely manner. Furthermore, because inspections are conducted manually, some problems are at risk of being overlooked. Therefore, there is an urgent need for a method, system, and equipment that can quickly locate faults in the actuator auxiliary equipment. Summary of the Invention

[0036] To better understand the technical solution of this invention, the content of this invention includes, but is not limited to, the specific embodiments described below. Similar technologies and methods should be considered within the scope of protection of this invention. To make the technical problems to be solved, the technical solutions, and advantages of this invention clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0037] It should be understood that the embodiments described in this invention are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0038] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0039] like Figure 1 As shown, the present invention provides a method for quickly locating faults in actuator auxiliary equipment, wherein the actuators are connected to nodes of the active reflector surface of the FAST telescope, and each actuator is connected to one node. The method includes the following steps:

[0040] S1. Tension the FAST active reflector surface into a sphere. After tensioning to the desired position, download and save the actual stroke values ​​of all actuators in this spherical state and measure the positions of all nodes.

[0041] S2. Calculate the deviation between the current sphere and the set ideal sphere and the overall deviation RMS value, and obtain the deviation values ​​of all the nodes;

[0042] S3. Process the actual stroke values ​​of all actuators in S1 with the deviation values ​​of all the nodes to obtain new stroke values ​​for all actuators;

[0043] S4. Repeat steps S1-S3, use the stroke value obtained in S3 to tension the FAST active reflector until the FAST active reflector is in the set ideal sphere, and save the stroke value of all actuators at this time, and use the stroke value as the reference value required for maintenance.

[0044] S5. When performing spherical calibration during maintenance, repeat steps S1-S2 using the reference values ​​to obtain the deviation values ​​of all the nodes;

[0045] S6. If the deviation value of some nodes in S5 exceeds the set threshold, it indicates that the actuator auxiliary equipment connected to these nodes has malfunctioned.

[0046] S7. After S6 is completed, jump to S4, execute to obtain the new travel value as a reference value, and repeat S5-S7 during the next maintenance.

[0047] S8. Save the faulty actuator number and deviation value to form a maintenance document, and provide it to maintenance personnel as a basis for targeted troubleshooting and handling.

[0048] Preferably, S1-S3 are repeated in S4 until the overall deviation RMS value is less than 1mm, so that the FAST active reflector is in the set ideal spherical surface.

[0049] Preferably, the standard for tensioning in S1 is that the deviation between the actual stroke value and the theoretical stroke value of the actuator is less than 200 micrometers.

[0050] Preferably, the theoretical sphere is a sphere with the origin of the FAST coordinate system as its center and a radius greater than or equal to 300 meters.

[0051] Preferably, the set threshold is 5mm.

[0052] Preferably, the FAST active reflector surface comprises 2225 nodes.

[0053] Preferably, all the actuators are numbered, and there are multiple sets of actuator accessories. Each set of actuator accessories includes an actuator, a pull cable, and an anchor. Each node is connected to the actuator via the pull cable, and the actuator is fixed to the ground by the anchor.

[0054] The FAST active reflector surface includes a main cable net, reflector surface units, and multiple sets of actuator auxiliary equipment, such as... Figure 4 As shown, each actuator accessory consists of a pull cable 3, an actuator 1, and an anchor 2. The main cable net is installed on a lattice-shaped ring beam and woven into a 500-meter diameter spherical surface using a geodesic grid. This spherical surface is woven from the main cable net, which contains 4450 reflective surface units (or panels). Each reflective surface unit includes 4300 triangular units and 150 quadrilateral units. The main cable net has 2225 nodes (4), which serve as the connection points for the main cable net. Each node is connected to an actuator (1) via a pull-down cable (3). The actuator (1) is fixed to the ground by anchor blocks (2). During astronomical observations, the position of the node (4) is adjusted by controlling the extension and retraction of the actuator (1), forming a 300-meter diameter instantaneous parabolic surface at a designated location on the 500-meter spherical surface. This allows the signal from the target celestial object to be focused onto the parabolic focal point for astronomical observation. This enables FAST to observe and track target celestial objects within a 40-degree zenith angle.

[0055] Since the main cable net of the FAST active reflector has 2225 nodes 4, each node 4 corresponds to a set of actuator auxiliary equipment and also corresponds to 6 reflector units. Except for the 150 quadrilaterals set at the edge, the internal reflector units can be regarded as equilateral triangles with a side length of about 11 meters. Therefore, if the position of one node 4 is inaccurate, it will affect the accuracy of the receiving area of ​​about 314 square meters.

[0056] This method utilizes spherical calibration data from FAST's maintenance period, and calculates the deviation of data measured at different nodes on the same spherical surface based on spherical calibration data from adjacent months during the maintenance period. The deviation value is used to determine whether the actuator auxiliary equipment at that location may have experienced problems such as cable pullback (3) or anchor pullout (also known as ground anchor). Nodes (4) potentially experiencing these problems are identified. Based on a pre-defined correspondence between nodes and actuators, the corresponding actuator (1) number is obtained, and maintenance personnel are notified to conduct focused inspections at the relevant locations. This improves the efficiency of problem detection and resolution, maximizes FAST's ultra-high sensitivity, and ensures that FAST produces greater and better scientific results.

[0057] Specifically, the operation process of this invention is as follows:

[0058] like Figure 2 As shown, the method of the present invention includes the following steps:

[0059] 1) Obtain the reference value of the FAST active reflector reference spherical surface. The present invention sets up a FAST active reflector control system for control. The FAST active reflector control system issues commands. After receiving the commands, FAST stretches the FAST active reflector into a spherical surface. After stretching to the position, it downloads and saves the stroke values ​​of all actuators.

[0060] 2) Keeping the spherical surface in place after step 1), measure the positions of 2225 nodes on the FAST active reflector surface;

[0061] 3) Subtract the node positions obtained in step 2) from the node positions under the current spherical state to obtain the deviation value. Calculate the overall deviation RMS (Root mean square) value of the sphere using the obtained deviation value, and record the deviation values ​​of all 2225 nodes.

[0062] 4) Add the deviation values ​​of all actuators obtained in step 3) to the actual actuator stroke values ​​obtained in step 1) to generate new actuator stroke values. Use these stroke values ​​to tension the sphere again to form a new sphere.

[0063] 5) Repeat steps 2) to 4) until the total deviation RMS value between the node position of the sphere calculated in step 3) and the theoretical sphere is less than 1mm. At this point, it is considered that the FAST active reflector is basically in the optimal reference sphere under the current actuator stroke value.

[0064] 6) Save and store the actuator stroke value corresponding to the optimal reference sphere obtained in step 5);

[0065] 7) Perform spherical accuracy measurement during the next maintenance period. The maintenance period refers to the shutdown and maintenance of FAST, which is generally 2 days per month. During the spherical calibration, the FAST active reflector surface is tensioned to form a reference sphere according to the actuator stroke value obtained in step 6). Then, steps 2) and 3) are performed in sequence. Considering the impact of systematic influences (such as temperature) on the measurement system, the deviation value of each node from the ideal sphere is different between the two measurements, but the difference should be small. If the deviation value of some nodes is large, such as exceeding 5mm, the problem of cable retraction or ground anchor being pulled out may occur. Filter out the corresponding nodes with large deviation values, find the actuator number corresponding to these nodes, and output the actuator number and the deviation value of the node corresponding to the actuator as a specified format file, which is provided to the maintenance personnel for point-to-point troubleshooting.

[0066] 8) After processing, jump to step 4) to obtain the new optimal reference sphere. Repeat steps 5) to 8) during the next maintenance.

[0067] As a further technical solution, the actuator stroke value obtained in step 1) is in micrometers.

[0068] As a further technical solution, the tensioning in step 2) means that the deviation between the actual stroke value of the actuator and the theoretical stroke value under the ideal spherical surface is less than 200 micrometers.

[0069] As a further technical solution, the measurement system used in step 2) should be calibrated before each measurement to avoid inaccurate measurement data caused by the measurement system.

[0070] As a further technical solution, the theoretical sphere referred to in step 3) is a sphere with the origin of the FAST coordinate system as the center and a radius of 300 meters.

[0071] As a further technical solution, in step 5), the spherical deviation RMS value should be as small as possible, at least below 1 mm.

[0072] As a further technical solution, the criterion for judging whether the pull-down cable has come loose or the ground anchor has been pulled out in step 7) is 5mm, but it can also be set to other values.

[0073] As a further technical solution, the file format specified in step 7) is suitable for the use of maintenance personnel, and can be images, txt documents, doc documents, Excel documents, etc.

[0074] In summary, this invention provides a method for rapidly locating actuator auxiliary equipment faults. Based on data from spherical calibration during FAST maintenance, it calculates the deviation between different target point positions during two spherical calibrations. The deviation value is used to determine whether the actuator at that location may have experienced problems such as cable retraction or ground anchor pull-out. Nodes potentially prone to these issues are identified, their actuator numbers are assigned, and maintenance personnel are notified to conduct focused inspections at those locations. This improves the efficiency of problem detection and resolution, ensuring the observation accuracy of FAST. This method is of great value for the maintenance of the FAST active reflector.

[0075] like Figure 3 As shown, this embodiment involves recalibration after maintenance. Each spherical calibration, with a cycle of approximately one month, suffers from varying climatic conditions in different months. Therefore, the actuator elongation (i.e., stroke value) corresponding to the theoretically acceptable spherical surface varies each time calibration is performed. Thus, after addressing any discovered faults each month, the spherical surface is recalibrated to obtain the actuator elongation corresponding to the ideal spherical surface meeting the set conditions for that month. This elongation serves as the target value for actuator tensioning during the next maintenance. Ideally, without any abnormalities in actuator auxiliary equipment, the spherical surface tensioned again using the same set of data after a one-month interval should show a small deviation between the tensioned spherical surface and the theoretical spherical surface compared to the previous calibration. The deviation value corresponding to each actuator should also be small. If the deviation value for a particular actuator is large, it indicates an abnormality in the actuator's auxiliary equipment. Monthly updates to the reference spherical surface data are implemented to avoid the influence of environmental factors. The recalibration method includes the following steps:

[0076] 1) Using the reference spherical data calibrated during the last maintenance, the FAST active reflector surface is tensioned into a spherical surface. After tensioning to the correct position, the actual stroke of the actuator is downloaded and saved.

[0077] 2) After tensioning the sphere in step 1), measure the positions of 2225 nodes on the FAST active reflector surface using a measurement system;

[0078] 3) Based on the data from step 2), after subtracting the distance between the target column and the reflecting surface, calculate the deviation between the current spherical state and the ideal spherical state, calculate the overall deviation RMS value, and obtain the deviation values ​​of 2225 nodes.

[0079] 4) Filter out the nodes with deviation values ​​greater than the given threshold from the 2225 nodes, and generate a list of nodes that need to be checked in a specified file format, along with their corresponding deviation values, based on the actuator number under each node. Provide this list to maintenance personnel for targeted troubleshooting.

[0080] 5) After the maintenance personnel have completed the inspection and handling, they add the deviation value obtained in step 3) to the actual actuator stroke value obtained in step 1), and then tension the spherical surface based on the calculated actuator stroke value.

[0081] 6) Repeat steps 2) and 3) until the obtained spherical deviation RMS value is less than 1mm. At this point, it is considered that the FAST active reflector is basically in the ideal spherical state under the current actuator stroke value.

[0082] 7) Save the actuator stroke value corresponding to the optimal reference sphere obtained in step 6) and store it in the FAST actuator control system;

[0083] 8) When calibrating the spherical surface during the next maintenance period, tension the reference spherical surface according to the actuator stroke value obtained in step 7), and then proceed to step 2) to execute.
