Description

Technical Field

[0001] This invention relates to the field of power transmission and transformation equipment monitoring and control technology, specifically to a substation monitoring and control device and method based on micro-meteorology. Background Technology

[0002] In the daily operation and maintenance of power systems, the operation and inspection of transmission and transformation equipment have long relied on two modes: one is regular inspections performed according to established procedures, and the other is passive response based on alarm signals. When encountering abnormal weather such as strong winds and heavy rain, transmission and transformation lines are prone to sudden situations such as wind-induced vibration and equipment failure. Under the traditional inspection mode, remote monitoring personnel cannot grasp the dynamic situation on site in real time, which often leads to the escalation of accidents and seriously affects the reliability of power supply.

[0003] Existing power transmission and transformation video surveillance systems have four major shortcomings: Firstly, camera adjustment relies on manual remote operation, making it impossible to make precise and automated adjustments based on micro-meteorological data such as wind speed and direction on site, and making it difficult to quickly capture first-person perspective footage after an accident. Secondly, upgrading the equipment requires replacing the entire camera, resulting in a serious waste of hardware resources and a significant increase in upgrade costs and construction time. Third, the power supply methods for monitoring devices are scattered, the wiring of various devices is cumbersome, the installation and deployment process is complicated, which affects the efficiency of operation and maintenance; Fourth, the camera's tilt adjustment structure is poorly designed, making it difficult to achieve fast and precise two-way angle control, and unable to meet the real-time adjustment requirements of micro-meteorological data linkage. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a substation monitoring and control method based on micrometeorology. This method overcomes the passive monitoring dilemma of existing monitoring systems that rely on manual adjustment and cannot respond to micrometeorological data. It enables automatic and precise adjustment of cameras based on wind speed and direction data, improves the proactiveness of monitoring under abnormal weather conditions, achieves rapid and accurate angle control, strengthens the targeting of monitoring under abnormal weather conditions, and accurately tracks risks and hidden dangers such as line wind deflection and galloping.

[0005] This invention is achieved through the following technical solution: In a first aspect, the present invention provides a substation monitoring and linkage device based on micro-meteorology, including a micro-meteorology acquisition device, a monitoring camera, a control box, and an integrated fixed bracket; the micro-meteorology acquisition device, the monitoring camera, and the control box are all mounted on the integrated fixed bracket; The control box has a built-in power module, switch, and main control module; the power module provides centralized power to the micro-meteorological acquisition device, monitoring camera, and main control module via PoE; the micro-meteorological acquisition device and monitoring camera are connected to the main control module via wired communication. The main control module is configured to receive real-time wind speed and direction data from the micro-meteorological acquisition device and generate angle control commands to adjust the orientation of the monitoring camera based on the data. The monitoring camera is mounted on a bidirectional adjustment mechanism, which is electrically connected to the main control module and is used to respond to the angle control commands to drive the monitoring camera to rotate in both horizontal and vertical directions.

[0006] Furthermore, the bidirectional adjustment mechanism includes a horizontal rotation component and a pitch adjustment component; The horizontal rotation assembly includes a first servo motor and a meshing drive gear and a driven gear; the center of the drive gear is mounted on the output shaft of the first servo motor, and the center of the driven gear has a through hole and is fixedly mounted on a hollow rotating shaft. The lower end of the hollow rotating shaft is rotatably mounted on a fixed base through a first bearing. The driven gear and its hollow rotating shaft can rotate around an axis perpendicular to the horizontal plane; it also includes a U-shaped support arm, which is fixed to the driven gear or the hollow rotating shaft and rotates horizontally with it. The pitch adjustment assembly includes a second servo, a push-pull rod, and a camera mounting bracket; The output shaft of the second servo motor is connected to the rotating arm; The camera mounting bracket is hinged to both ends of the support arm via a horizontally set hinge axis; the surveillance camera is fixed on the camera mounting bracket. The push-pull rod passes through the inner cavity of the hollow rotating shaft; the lower end of the push-pull rod is hinged to one end of the rotating arm, and the upper end of the push-pull rod is hinged to the camera mounting bracket. The second servo motor drives the push-pull rod to extend and retract along its axis, thereby adjusting the pitch angle of the camera mounting bracket and the monitoring camera around the hinge axis.

[0007] By combining the horizontal rotation axis and the pitch adjustment transmission rod into one, the overlapping utilization of the motion channel is achieved. This minimizes the axial dimension and radial space occupied by the entire bidirectional adjustment mechanism, resulting in a very compact structure. The advantages include a lighter device, easier installation on existing substation towers with strict space constraints, and mechanical decoupling of the two degrees of freedom of motion. During horizontal rotation, the push-pull rod can freely rotate within the axis; during pitch adjustment, the push-pull rod moves linearly within the axis without affecting the horizontal angle. This design avoids motion interference, eliminates the risk of jamming, and enables a fast and precise response to control commands, achieving "fast and precise angle control." Furthermore, the gear transmission and servo motor themselves possess a certain degree of self-locking; when the camera rotates to the target angle, the mechanism can maintain its position stability through mechanical self-locking, preventing displacement due to wind or vibration. This ensures that, even in abnormal weather conditions, the monitoring image remains consistently and stably focused on the risk point, providing maintenance personnel with reliable on-site footage.

[0008] Furthermore, a second bearing is fixedly installed in the through hole at the center of the driven gear or in the inner cavity of the hollow rotating shaft, and the push-pull rod passes through the second bearing; the second bearing is a linear bearing or a sliding bearing, used to constrain the radial displacement of the push-pull rod and guide it to perform axial extension and retraction.

[0009] The hollow rotating shaft serves as the main load-bearing and transmission component. Its interior is equipped with linear bearings to guide the push-pull rod. As an integral component, the hollow shaft has a strength and rigidity far superior to the split assembly structure, and can reliably withstand the camera load and wind load. The linear bearing is specially designed for linear motion, which greatly reduces friction and radial wobble during the movement of the push-pull rod, avoids direct wear between the push-pull rod and the inner wall of the shaft, and improves the smoothness of movement and the life of the mechanism.

[0010] Furthermore, the integrated fixed bracket includes a mounting base and a vertical pole connected to the mounting base. The micro-weather acquisition device is installed at the top of the pole, the control box is installed on the pole, and a bracket is vertically connected to the pole below the micro-weather acquisition device. The monitoring camera is installed on the bracket through a two-way adjustment mechanism.

[0011] As a preferred option, the control box also includes a universal adapter module, which enables the main control module to communicate with different models of surveillance cameras.

[0012] By setting up an adaptation module, the problem of wasted resources that requires replacing the entire camera during equipment upgrades can be solved, and a low-cost upgrade solution for existing cameras can be built to reduce the investment in modification.

[0013] Secondly, the present invention provides a control method for a substation monitoring and linkage device based on micro-meteorology, comprising the following steps: Step S1: Obtain real-time wind speed and direction data for the monitored area using a micro-meteorological data acquisition device; Step S2: The main control module of the control box receives wind speed and wind direction data and parses out the wind direction coordinates; In this invention, the fundamental mathematical principles for calculating wind direction vectors are mature existing technologies. Vector decomposition and coordinate transformation serve as the basic algorithms, which are the most direct and completely public algorithms. The steps are described in any meteorology or engineering mathematics textbook. 1. Data Acquisition: Micro-weather sensors typically provide two parameters: Wind direction angle (θ): refers to the direction from which the wind blows, usually with due north as 0° and increasing clockwise.

[0014] Wind speed (v): The speed of the wind.

[0015] 2. Vector Conversion: Converts wind direction and speed into two-dimensional planar vectors.

[0016] North component: V_north = v cos(θ) Eastward component: V_east = v sin(θ) This vector (V_east, V_north) represents the vector indicating the direction of the wind.

[0017] 3. Coordinate transformation (optional but common): Transform the geographic coordinate system (based on true north) to the local coordinate system where the camera is located. The initial installation azimuth angle (α) of the camera needs to be considered. Therefore, the horizontal angle the camera needs to rotate (relative to its initial position) might be θ – α.

[0018] The present invention essentially converts data collected by micro-meteorological sensors (usually wind speed and wind direction angle) into a target angle that is available in the camera coordinate system.

[0019] Step S3: The main control module generates the corresponding camera angle adjustment command based on the coordinates of the incoming wind direction; Step S4: Send the angle adjustment command to the bidirectional adjustment mechanism to drive the monitoring camera to rotate so that the monitoring camera faces the direction of the wind.

[0020] Furthermore, when the substation monitoring and linkage device is deployed in multiple areas, the method also includes a multi-area linkage monitoring step: Step A: Obtain micro-meteorological monitoring data of power transmission and transformation equipment in each area, and set corresponding characteristic thresholds for different area types; Step B: When the meteorological data of a certain area exceeds its corresponding characteristic threshold, the area is determined to be an alarm area; Step C: Based on spatial correlation analysis, calculate the spatial weight of the alarm area and other areas, and select at least one other area with the highest spatial weight value as the linkage area; Step D: Adjust the camera angle of the monitoring linkage device corresponding to the linkage area so that it faces the alarm area for monitoring.

[0021] Furthermore, in step C, the spatial weights are calculated using the spatial weight matrix, and the calculation formula is as follows: ; In the formula, and For different power transmission and transformation equipment, for and For different spacing of power transmission and transformation equipment, This is the spatial weight matrix for power transmission and transformation equipment. This is the distance attenuation coefficient.

[0022] Furthermore, in step A, the micrometeorological monitoring data for different regional types are normalized using the following formula: ; In the formula: These are the original meteorological monitoring parameter values. These are the standardized meteorological parameter values, ranging from [0, 1]. This is the original meteorological monitoring parameter sequence.

[0023] Furthermore, the regional types include high mountain watersheds, canyon wind corridors, icing areas, and flood-prone areas; the characteristic thresholds include one or more combinations of wind speed, sudden temperature changes, instantaneous wind speed, sudden changes in wind direction, icing thickness, and precipitation.

[0024] The beneficial effects of this invention are: This invention integrates a micro-meteorological data acquisition device, monitoring camera, control box, switch, power supply, and other auxiliary materials into a unified installation. The bracket is compatible with existing monitoring poles and other installation scenarios, allowing direct connection to existing cameras without requiring a complete hardware replacement, thus lowering the upgrade threshold. Employing PoE (Power over Ethernet) technology, it integrates the power module and switch functions to achieve centralized power supply for all devices, simplifying wiring layout and completely resolving the cumbersome wiring issues caused by distributed power supply for multiple devices. The camera receives real-time wind speed and direction data from the micro-meteorological data acquisition device, analyzes the wind direction coordinates, and automatically generates angle adjustment commands, providing logical support for precise camera turning. A stable communication link is established between the micro-meteorological data acquisition device, camera, and control box via an RJ45 interface, ensuring real-time transmission of meteorological data and rapid issuance of adjustment commands. The control box has a built-in universal adapter module, compatible with mainstream monitoring camera models on the market, allowing for upgrades without modifying the core camera components.

[0025] A mechanical structure with dual servo motors working in tandem enables precise bidirectional adjustment of the camera, meeting the dynamic tracking needs of risks and hazards under abnormal weather conditions. The first servo motor drives a driven gear via gear transmission, thereby rotating the camera left and right. The second servo motor, through its rotating arm, links a push-pull rod to move up and down, using the extension and retraction of the rod to adjust the camera's vertical angle. This dual-structure synergistic response to adjustment commands ensures the camera quickly and accurately turns towards the wind direction, significantly improving emergency response speed under abnormal weather conditions and facilitating rapid handling of emergencies.

[0026] This invention overcomes the limitations of existing monitoring systems that rely on manual adjustments and are unable to respond to micro-meteorological data, enabling automatic and precise camera adjustment based on wind speed and direction data, thus enhancing proactive monitoring during abnormal weather conditions. It also addresses the resource waste associated with replacing all cameras during equipment upgrades by providing a low-cost upgrade solution for existing cameras, reducing retrofit investment. Furthermore, it optimizes the power supply and installation methods, resolving issues of dispersed power supply, cumbersome wiring, and complex installation, improving deployment and ease of use. The innovative bidirectional camera adjustment hardware structure, along with improved hardware support and algorithmic logic for wind direction adjustment, enables rapid and precise angle control, enhancing the targeting of monitoring during abnormal weather conditions and accurately tracking risks such as line drift and swaying.

[0033] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0034] Example 1: A substation monitoring and linkage device based on micro-meteorology includes a micro-meteorology acquisition device 2, a monitoring camera 3, a control box 4, and an integrated fixed bracket. The micro-meteorology acquisition device 2, the monitoring camera 3, and the control box 4 are all mounted on the integrated fixed bracket. The integrated fixed bracket includes a mounting base and a vertical pole 1 connected to the mounting base. The micro-meteorology acquisition device 2 is mounted on the top of the pole 1, the control box 4 is mounted on the pole 1, and a bracket 6 is vertically connected to the pole 1 below the micro-meteorology acquisition device 2. The monitoring camera 3 is mounted on the bracket 6 through a bidirectional adjustment mechanism 5.

[0035] The control box 4 houses a power module, a switch, and a main control module. It also includes a universal adapter module that enables the main control module to communicate with different types of monitoring cameras. The power module provides centralized power to the micro-meteorological data acquisition device 2, the monitoring camera 3, and the main control module via PoE. The micro-meteorological data acquisition device 2 and the monitoring camera 3 are connected to the main control module via wired communication. The main control module is configured to receive wind speed and direction data collected in real time by the micro-meteorological acquisition device 2, and generate angle control commands for adjusting the orientation of the monitoring camera 3 based on the data. The monitoring camera 3 is mounted on a bidirectional adjustment mechanism 5, which is electrically connected to the main control module and is used to respond to the angle control commands to drive the monitoring camera 3 to rotate in both horizontal and vertical directions.

[0036] The bidirectional adjustment mechanism 5 includes a horizontal rotation component and a pitch adjustment component; the horizontal rotation component includes a first servo motor 55 and a meshing drive gear 56 and a driven gear 54; the drive gear 56 is centrally mounted on the output shaft of the first servo motor 22, the driven gear 54 has a through hole in its center and is fixedly mounted on a hollow rotating shaft 53, the lower end of the hollow rotating shaft 53 is rotatably mounted on a fixed base 51 through a first bearing 52, and the driven gear 54 and its hollow rotating shaft 53 can rotate around an axis perpendicular to the horizontal plane; it also includes a U-shaped support arm 57, the support arm 57 is fixed on the driven gear 54 or the hollow rotating shaft 53 and rotates horizontally with it.

[0037] The pitch adjustment assembly includes a second servo motor 511, a push-pull rod 510, and a camera mounting bracket 58; the output shaft of the second servo motor 511 is connected to a rotating arm 512; the camera mounting bracket 58 is hinged to both ends of a support arm 57 via a horizontally arranged hinge shaft 59; the monitoring camera 3 is fixed on the camera mounting bracket 58; the push-pull rod 510 passes through the inner cavity of the hollow rotating shaft 53; the lower end of the push-pull rod 510 is hinged to one end of the rotating arm 512, and the upper end of the push-pull rod 510 is hinged to the camera mounting bracket 58 via a fixed shaft 513; The second servo motor 511 drives the push-pull rod 510 to extend and retract along its axis, thereby causing the camera mounting bracket 58 and the monitoring camera 3 to adjust their pitch angle around the hinge axis 59.

[0038] A second bearing 514 is also fixedly installed inside the hollow rotating shaft 53, and the push-pull rod 510 passes through the second bearing 514; the second bearing 514 is a linear bearing or a sliding bearing, used to constrain the radial displacement of the push-pull rod 510 and guide it to perform axial extension and retraction.

[0039] like Figure 1 and Figure 2 As shown, a micro-meteorological acquisition device 2 (this is existing technology; generally, a wind speed and direction sensor can be used to measure wind speed and direction), a monitoring camera 3, and a control box 4 are installed at the top of the pole 1. The control box 4 integrates a PoE power module, a switch, and a main control module (such as an embedded industrial computer). All devices are connected to the control box 4 via a single network cable for power supply and communication.

[0040] The bidirectional adjustment mechanism 5 is the core component. Its fixed base 51 is bolted to the bracket 6. A first bearing 52 is installed inside the fixed base 51. The hollow rotating shaft 53 is supported in the bearing 52 and can rotate about the vertical axis. The driven gear 54 is fixed to the hollow rotating shaft 53 by a key connection. The driving gear 56 driven by the first servo motor 55 meshes with the driven gear 54. The lower end of the support arm 57 is fixed to the upper end of the hollow rotating shaft 53 by a flange.

[0041] The camera mounting bracket 58 is hinged to the upper end of the support arm 57 via a horizontal hinge shaft 59. The push-pull rod 510 passes through the inner cavity of the hollow rotating shaft 53, with its lower end hinged to the rotating arm on the output shaft of the second servo motor 511 and its upper end hinged to the camera mounting bracket 58. A second bearing 514 is press-fitted into the inner cavity of the hollow rotating shaft 53, through which the push-pull rod 510 passes, ensuring that it can only move axially.

[0042] The main control module of control box 4 receives micro-meteorological data through the RJ45 interface and controls the first servo motor 55 and the second servo motor 511 to operate.

[0043] Example 2: A control method for a substation monitoring and linkage device based on micro-meteorology includes the following steps: Step S1: Obtain wind speed and direction data of the monitoring area in real time through a micro-meteorological acquisition device; the area types include high mountain watersheds, canyon wind corridors, icing areas, and flood-prone areas; the characteristic thresholds include one or more combinations of wind speed, sudden temperature change, instantaneous wind speed, sudden wind direction change, icing thickness, and precipitation.

[0044] Step S2: The main control module of the control box receives wind speed and wind direction data and parses out the wind direction coordinates; Step S3: The main control module generates the corresponding camera angle adjustment command based on the coordinates of the incoming wind direction; Step S4: Send the angle adjustment command to the bidirectional adjustment mechanism to drive the monitoring camera to rotate so that the monitoring camera faces the direction of the wind.

[0045] When the substation monitoring and linkage device is deployed in multiple areas, the method also includes a multi-area linkage monitoring step: Step A: Obtain micro-meteorological monitoring data of power transmission and transformation equipment in each area, and set corresponding characteristic thresholds for different area types; Step B: When the meteorological data of a certain area exceeds its corresponding characteristic threshold, the area is determined to be an alarm area; Step C: Based on spatial correlation analysis, calculate the spatial weight of the alarm area and other areas, and select at least one other area with the highest spatial weight value as the linkage area; Step D: Adjust the camera angle of the monitoring linkage device corresponding to the linkage area so that it faces the alarm area for monitoring.

[0046] In step C, the spatial weights are calculated using the spatial weight matrix, and the calculation formula is as follows: ; In the formula, and For different power transmission and transformation equipment, for and For different spacing of power transmission and transformation equipment, This is the spatial weight matrix for power transmission and transformation equipment. This is the distance attenuation coefficient.

[0047] In step A, the micrometeorological monitoring data for different regional types are normalized using the following formula: ; In the formula: These are the original meteorological monitoring parameter values. These are the standardized meteorological parameter values, ranging from [0, 1]. This is the original meteorological monitoring parameter sequence.

[0048] like Figure 3 As shown, the normal single-point monitoring process is as follows: the micro-meteorological acquisition device 2 continuously collects wind speed and direction data and sends it to the main control module. The main control module calculates the horizontal angle α and pitch angle β that make the monitoring camera face the direction of the incoming wind. Subsequently, the main control module sends commands to the first servo motor 55 and the second servo motor 511 to drive the gear mechanism to rotate by angle α, while simultaneously driving the push-pull rod 510 to extend or retract to the corresponding position of angle β, completing the adjustment. Figure 4As shown, when the system includes multiple monitoring points, multi-area linkage is initiated. Assuming the instantaneous wind speed at site A (canyon wind tunnel) exceeds the threshold of 20 m / s, the system determines A as an alarm area. Subsequently, the system calculates the spatial weights of other sites (B, C, D...) relative to A. The calculation shows that site B has the highest weight, so the system automatically adjusts the camera at site B to face the direction of site A, assisting maintenance personnel in observing the on-site situation at site A and achieving joint monitoring.
