Description

Technical Field

[0001] This invention relates to the field of verification device technology, and in particular to an automatic verification device and method for power distribution network topology. Background Technology

[0002] Power distribution network topology refers to the physical layout of various devices such as computers interconnected by transmission media. It refers to the geometric shape formed during the interconnection process. It can represent the network configuration of network servers and workstations and their interconnections. It is often used for the management of power distribution lines. It does not consider the actual location of electronic devices, but simply represents the relationship between electronic devices and network devices in the network. Before using power distribution network topology, the connections between electronic devices and network devices need to be verified.

[0003] Traditional verification methods have the following drawbacks:

[0004] (1) The traditional verification method is to manually use power inspection equipment to check the power of each connection of the power distribution network topology. This verification method consumes a lot of manpower and resources and has very low verification efficiency.

[0005] (2) Traditional verification methods rely solely on the experience of the verification personnel to verify typical working conditions, which can easily lead to verification errors. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic power distribution network topology verification device and method. By formulating a verification route based on the power distribution network topology information and automatically performing network topology verification according to the verification route, this invention solves the problems of low verification efficiency and easy errors in the existing method of manually checking the power connections of the power distribution network topology one by one using power inspection equipment. This invention improves the verification efficiency and accuracy of power distribution network topology.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] An automatic topology verification device for power distribution lines, controlled by a monitoring backend, includes a control module, a traveling frame, a position adjustment mechanism, a verification mechanism, and a communication module. The traveling frame, position adjustment mechanism, verification mechanism, and communication module are all connected to the control module. The control module communicates with the monitoring backend via the communication module. The control module determines the verification route and all locations to be verified based on the power distribution network topology information from the monitoring backend. Based on the verification route and all locations to be verified, it determines the movement trajectory of the traveling frame and the verification information corresponding to each location. The traveling frame moves according to the verification route determined by the control module and stops upon reaching each location to be verified. The position adjustment mechanism adjusts the position of the verification mechanism according to the verification information corresponding to each location to be verified determined by the control module. The verification mechanism verifies line loss, line position, transformer position, and automatic distribution switch at the locations to be verified. The control module also determines the line operating status at the locations to be verified based on the verification results of the verification mechanism and feeds back the line operating status determination results to the monitoring backend via the communication module.

[0009] Furthermore, the position adjustment mechanism includes a calibration shell, a calibration platform, a turntable, and a lifting mechanism. The calibration shell is fixedly connected to the top of the walking frame, the calibration platform is fixedly installed on the top of the calibration shell, the top of the calibration platform is rotatably connected to the turntable, and the top of the turntable is fixedly installed with the lifting mechanism. The lifting mechanism includes a lifting platform and a mounting plate. The calibration mechanism is fixedly connected to the side of the mounting plate. The turntable is used to adjust the calibration direction of the calibration mechanism, and the lifting mechanism is used to adjust the calibration height of the calibration mechanism.

[0010] Furthermore, the verification mechanism includes a translation frame, an angle plate, a line loss camera, a line transformer camera, a locator, and a distribution switch connector. The line loss camera, line transformer camera, and locator are all connected to the angle plate, which is also connected to the translation frame. The angle plate and the translation frame cooperate to control the verification angle of the line loss camera, line transformer camera, and locator. The distribution switch connector is installed on the verification shell and is connected to an external distribution switch to obtain the topological relationship between the distribution switch and the distribution transformer. The line loss camera is used to acquire the line operation image of the high-loss and negative-loss lines corresponding to the location to be verified. The line transformer camera is used to acquire the outage status of all distribution transformers on the corresponding distribution line at the location to be verified. The locator is used to acquire the position of all distribution transformers on the corresponding distribution line at the location to be verified.

[0011] An automatic topology verification method for power distribution network, applied to the aforementioned automatic topology verification device for power distribution network, includes:

[0012] The system acquires the power distribution line network topology information and determines the verification route based on the information. It then identifies all locations to be verified along the verification route. The automatic power distribution line network topology verification device moves along the verification route using a walking frame, and when it detects that it has reached one of the locations to be verified, it determines the network topology information of that location based on the verification route.

[0013] Based on the network topology information of the location to be verified, the corresponding verification information is determined. The location of the verification mechanism is adjusted based on the determined verification information. After the location adjustment of the verification mechanism is completed, the line loss, line, transformer location and distribution switch are verified by the verification mechanism. All verification results are bound to the location to be verified and sent to the monitoring backend.

[0014] After completing the verification of the reached location, the walking frame continues to move along the verification route until all locations have been verified.

[0015] Furthermore, the verification information includes the power distribution line corresponding to the location to be verified, the transformer information on the power distribution line, and the line-transformer relationship of the power distribution line.

[0016] Furthermore, after the position adjustment of the verification mechanism is completed, when the line loss, line, transformer position and automatic switch are verified by the verification mechanism, the verification angle of the line loss, line and transformer position is also adjusted by the translation frame and angle plate.

[0017] Furthermore, when adjusting the verification angles of line loss, line, and transformer position using the translation frame and angle plate, the position to be verified is first determined. Historical verification data and line operation data of the position to be verified are retrieved from the monitoring backend. Based on the historical verification data and line operation data, the risk levels of line loss verification, line verification, and transformer position verification are classified. The order of adjustment of the verification angles for line loss verification, line verification, and transformer position verification is determined according to the risk level classification results. The corresponding verification angles for line loss verification, line verification, and transformer position verification are determined according to the historical verification data. The translation frame and angle plate are then used to adjust the verification angles of line loss verification, line verification, and transformer position verification in the order of the verification angle adjustment.

[0018] The beneficial effects of this invention are:

[0019] It can determine the corresponding verification route based on the power distribution line network topology information, and automatically verify each location to be verified by moving along the verification route. This achieves the verification of the power distribution line network topology without the need for manual verification, saving significant manpower and resources and improving the efficiency of network topology verification. Furthermore, it can perform verification from multiple directions, including line loss, lines, transformer locations, and automatic switchgear, avoiding verification errors and omissions.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Example:

[0028] An automatic topology verification device for power distribution lines, controlled by a monitoring backend 6, such as... Figure 1As shown, the system includes a control module 1, a walking frame 2, a position adjustment mechanism 3, a verification mechanism 4, and a communication module 5. The walking frame, position adjustment mechanism, verification mechanism, and communication module are all connected to the control module. The control module communicates with the monitoring backend via the communication module. The control module determines the verification route and all locations to be verified based on the power distribution network topology information from the monitoring backend. Based on the verification route and all locations to be verified, it determines the movement trajectory of the walking frame and the verification information corresponding to each location. The walking frame moves according to the verification route determined by the control module and stops upon reaching each location to be verified. The position adjustment mechanism adjusts the position of the verification mechanism according to the verification information corresponding to each location to be verified determined by the control module. The verification mechanism performs line loss, line, transformer position, and automatic distribution switch verification at the locations to be verified. The control module also determines the line operating status of the locations to be verified based on the verification results of the verification mechanism and feeds back the line operating status determination results to the monitoring backend via the communication module.

[0029] The control module can be a data analysis and processing chip such as a microprocessor.

[0030] The position adjustment mechanism includes a calibration shell 31, a calibration platform 32, a turntable 33, and a lifting mechanism 34. The calibration shell is fixedly connected to the top of the walking frame. The calibration platform is fixedly installed on the top of the calibration shell. The top of the calibration platform is rotatably connected to the turntable. The top of the turntable is fixedly installed with the lifting mechanism. The lifting mechanism includes a lifting platform 341 and a mounting plate 342. The calibration mechanism is fixedly connected to the side of the mounting plate. The turntable is used to adjust the calibration direction of the calibration mechanism, and the lifting mechanism is used to adjust the calibration height of the calibration mechanism.

[0031] The verification shell also has a partition fixedly installed inside, and a servo motor is fixedly installed at the bottom of the partition. An active umbrella-shaped helical tooth is fixedly installed at the output end of the servo motor. The control module controls the movement of the walking frame by controlling the servo motor.

[0032] A rotary motor is also fixedly installed at the top of the partition. The output end of the rotary motor passes through the verification shell and is fixedly connected to the middle of the bottom of the turntable. After the rotary motor is started under the control of the control module, the rotary motor drives the turntable to rotate, thereby adjusting the verification direction of the verification mechanism.

[0033] Specifically, the structural diagram of the walking frame is as follows: Figure 2As shown, a first rotating shaft 22 and a second rotating shaft 25 are rotatably connected to both sides of the inner wall of the walking frame. Moving wheels 21 are fixedly installed at both ends of the first and second rotating shafts, passing through the walking frame. A driven umbrella-shaped helical tooth 23 is fixedly installed in the middle of the first rotating shaft. Pulleys 24 are fixedly installed on the surfaces of both the first and second rotating shafts, and a belt connects the two pulleys. The outer side of the active umbrella-shaped helical tooth meshes with the outer side of the driven umbrella-shaped helical tooth. When the servo motor is powered on, it starts, driving the active umbrella-shaped helical tooth to rotate. The active umbrella-shaped helical tooth contacts the driven umbrella-shaped helical tooth, causing the driven umbrella-shaped helical tooth to rotate due to friction. The driven umbrella-shaped helical tooth drives the first rotating shaft to rotate. The first rotating shaft transmits the rotational power to the second rotating shaft through the pulleys and belt. The moving wheels on the second and first rotating shafts rotate, facilitating the movement of the verification shell along the power distribution network topology.

[0034] The structural diagram of the lifting mechanism is shown below. Figure 3 As shown, upright plates 348 are fixedly installed on both sides of the top of the lifting platform. Lifting grooves 344 are opened on the opposite side of the two upright plates. Lifting blocks 345 are slidably connected inside the two lifting grooves. One side of the two lifting blocks is fixedly connected to the two sides of the mounting plate. A first motor 346 is fixedly installed in the middle of the top of the lifting platform. A threaded column 347 is fixedly installed at the output end of the first motor. A limit plate is fixedly installed at the top of the threaded column. The middle of the threaded column is threadedly connected to the inside of the mounting plate. The bottom of the lifting platform is fixedly connected to the turntable. When the first motor is powered on, it starts and drives the threaded column to rotate. The threads on the surface of the threaded column match the threads on the inner wall of the mounting plate. The mounting plate is limited by the lifting blocks on both sides. The lifting blocks slide along the lifting grooves. At this time, the mounting plate slides along the threaded column, thereby adjusting the verification height of the verification mechanism.

[0035] The verification mechanism includes a translation frame 41, an angle plate 42, a line loss camera 43, a line transformer camera 44, a locator 45, and a distribution switch connector. The line loss camera, line transformer camera, and locator are all connected to the angle plate, which is also connected to the translation frame. The angle plate and the translation frame cooperate to control the verification angle of the line loss camera, line transformer camera, and locator. The distribution switch connector is installed on the verification shell and is connected to an external distribution switch to obtain the topological relationship between the distribution switch and the distribution transformer. The line loss camera is used to acquire the line operation image of the high-loss and negative-loss lines corresponding to the location to be verified. The line transformer camera is used to acquire the outage status of all distribution transformers on the corresponding distribution line at the location to be verified. The locator is used to acquire the position of all distribution transformers on the corresponding distribution line at the location to be verified.

[0036] Specifically, a translation groove 411 is provided on one side of the bottom end of the translation frame. A lead screw 48 is rotatably connected inside the translation groove. A translation block 47, which is slidably connected to the translation groove, is threadedly connected to the middle of the lead screw. A push rod 410 is rotatably connected to the bottom end of the translation block. A connecting rod 49 is rotatably connected to one side of the translation frame. The end of the connecting rod away from the translation frame is fixedly connected to one end of the angle plate. The end of the push rod away from the translation block is precisely connected to the middle of the angle plate. One side of the line loss camera, one side of the line conversion camera, and one side of the locator are all fixedly connected to the other side of the angle plate. The thread on the surface of the lead screw matches the thread on the inner wall of the translation block. The translation block is limited by the translation groove, which matches its shape and size. Therefore, the translation block slides along the lead screw. During the sliding process, the push rod is pulled from one side. The length of the push rod remains unchanged, which changes the vertical height of the push rod. At this time, the angle plate changes angle along the translation frame with the connecting rod, adjusting the angle of the angle plate and indirectly adjusting the calibration angle.

[0037] Furthermore, the side of the translation frame away from the angle plate is fixedly connected to the mounting plate. A second motor is fixedly installed on the surface of the mounting plate. The output end of the second motor passes through the mounting plate and the end of the translation frame that is directly opposite the lead screw. When the second motor is powered on, it starts and drives the lead screw to rotate.

[0038] Specifically, the structural diagram of the verification mechanism is as follows: Figure 4 As shown.

[0039] An automatic topology verification method for power distribution network is applied to the aforementioned automatic topology verification device for power distribution network, such as... Figure 5 As shown, it includes:

[0040] Obtain the power distribution line network topology information and determine the verification route based on the power distribution line network topology information;

[0041] The automatic power distribution network topology verification device moves along the verification route using a walking frame to determine all locations to be verified on the verification route. When it detects that it has reached one of the locations to be verified, it determines the network topology information of the location to be verified based on the verification route.

[0042] Based on the network topology information of the location to be verified, the corresponding verification information is determined. The location of the verification mechanism is adjusted based on the determined verification information. After the location adjustment of the verification mechanism is completed, the line loss, line, transformer location and distribution switch are verified by the verification mechanism. All verification results are bound to the location to be verified and sent to the monitoring backend.

[0043] After completing the verification of the reached location, the walking frame continues to move along the verification route until all locations have been verified.

[0044] The verification information includes the power distribution line corresponding to the location to be verified, the transformer information on the power distribution line, and the line-transformer relationship of the power distribution line.

[0045] After the position adjustment of the verification mechanism is completed, when the line loss, line, transformer position and automatic switch are verified by the verification mechanism, the verification angle of the line loss, line and transformer position is also adjusted by the translation frame and angle plate.

[0046] When adjusting the verification angles for line loss, line, and transformer position using a translation frame and angle plate, first determine the position to be verified. Retrieve historical verification data and line operation data for the position to be verified from the monitoring backend. Based on the historical verification data and line operation data, classify the risk levels for line loss verification, line verification, and transformer position verification. Determine the order of angle adjustment for line loss verification, line verification, and transformer position verification based on the risk level classification results. Determine the corresponding verification angles for line loss verification, line verification, and transformer position verification based on the historical verification data. Then, adjust the verification angles for line loss verification, line verification, and transformer position verification sequentially using the translation frame and angle plate according to the order of angle adjustment.

[0047] Since different verification types require different verification information, the verification angle needs to be adjusted according to the verification type to ensure that the verification results of each verification type are accurate.

[0048] During the verification process of different verification types, the types of faults and anomalies that may be identified may differ, and the risk levels caused by different types of faults and anomalies are also different. Therefore, based on historical verification data, it is possible to determine the verification type that is prone to anomalies at each location to be verified. At the same time, by obtaining the line operation data, the current fault risks that may exist in the line can be obtained. Thus, the probability of faults that may be found in each verification type can be divided. The verification type that is more likely to cause a fault has a higher risk level. The verification of the verification type with a higher risk level should be prioritized to detect faults and anomalies in the power distribution line as early as possible and reduce the impact of faults.

[0049] After acquiring the high-loss and low-loss line operation images at the location to be verified by the line loss camera, the control module compares the line change relationship calculation results in the verification information with the acquired high-loss and low-loss line operation images, and sends the corresponding data governance work order to the monitoring backend based on the comparison results to complete the line loss verification.

[0050] The control module also uses a full-line power outage as a basis, combined with the outage status of distribution transformers under the jurisdiction of the distribution line obtained by the line transformer cameras, to determine abnormal line-transformer relationships for transformers that should have been shut down but were not. Simultaneously, the control module also sets relative thresholds for line transformer positions, calculates outlier transformers based on the locator's verification results, and determines that the line transformer verification results for outlier transformers exceeding the threshold are abnormal. The abnormal line-transformer relationship information for transformers that should have been shut down but were not, along with the information on transformers with identified abnormal line-transformer relationships, is sent to the monitoring backend to complete line verification and line transformer position verification.

[0051] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
