Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line monitoring, and in particular to a transmission line tower inclination monitoring and control method and system. Background Art

[0002] With the rapid development of the power system, the safety and stability of high-voltage transmission lines have become the focus of the power supply industry. The structural health of transmission line towers directly affects the reliable operation of the power grid. The tilt of towers is often caused by factors such as wind and geological activities. If not discovered and handled in time, it may lead to serious safety hazards such as displacement and grounding of transmission lines. At present, most tower tilt monitoring solutions rely on ground inspections or regular manual inspections. However, such methods are time-consuming and labor-intensive, and it is difficult to achieve real-time monitoring, and cannot effectively deal with sudden or cumulative tilt problems. With the rapid development of the Internet of Things (IoT) and wireless transmission technology, the use of sensors and intelligent terminal devices to automatically monitor tower tilt has gradually become a research hotspot. Real-time data collection and transmission through wireless transmission protocols are expected to achieve continuous monitoring of tower status and intelligent early warning, thereby improving line maintenance efficiency and safety.

[0003] The existing tower tilt monitoring technology has the following main shortcomings. First, the traditional method relies on manual inspection or regular ground inspection, which makes it difficult to achieve real-time and high-frequency data collection, making it impossible to quickly learn about the tower tilt problem in a short period of time, which can easily cause safety hazards. Secondly, the existing automated monitoring schemes mostly rely on fixed sensors for tilt data collection, but the sensor fault monitoring mechanism is imperfect. If the sensor misreports or fails to alarm in time, it is difficult to ensure the accuracy of the data, affecting the effectiveness of the monitoring system. In addition, the existing tilt monitoring methods mostly do not consider the application of drone-assisted inspections, and fail to achieve regular inspections of the all-round status of the tower, increasing the maintenance cost and personnel safety risks of the equipment in the long-term operation. In contrast, the transmission line tower tilt monitoring system proposed in the present invention has been technically optimized in many aspects: the alarm threshold of the monitoring module is initialized and set through the intelligent terminal and Bluetooth connection, so that the alarm parameters of each module are personalized, and the real-time detection and judgment of the tower tilt state are realized by combining drone inspections with module self-inspection, which significantly improves the accuracy and efficiency of monitoring and achieves a safety protection effect that is difficult to achieve with traditional technologies. Summary of the invention

[0004] In view of the above-mentioned problems, the present invention is proposed.

[0005] Therefore, the technical problem solved by the present invention is that the existing tower tilt monitoring method has the problems of insufficient real-time performance, low alarm accuracy, lack of efficient inspection support, and how to achieve reliable and accurate tilt monitoring and early warning.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: a transmission line tower tilt monitoring and control method, comprising initializing and functional testing a first module; installing and calibrating the first module; and making a first alarm determination based on a status check.

[0009] As a preferred solution of the transmission line tower inclination monitoring and control method described in the present invention, wherein: the installation location is the tower to be monitored.

[0010] As a preferred solution of the transmission line tower inclination monitoring and control method described in the present invention, the calibration includes calibrating with the current photovoltaic panel plane as the reference horizontal plane.

[0011] As a preferred solution of the transmission line tower inclination monitoring and control method described in the present invention, the first alarm determination based on status check includes regular inspection and recording of the status of the first module.

[0012] As a preferred solution of the transmission line tower inclination monitoring and control method described in the present invention, the first alarm determination based on the status check includes performing an on-site reset as required.

[0013] Another object of the present invention is to provide a transmission line tower tilt monitoring and control system, which can perform a first alarm judgment based on a status check, thereby solving the problem of low alarm accuracy in current tower tilt monitoring methods.

[0014] As a preferred solution of the transmission line tower inclination monitoring and control system described in the present invention, it includes: an initialization module, a monitoring and testing module, and a status check alarm module; the initialization module is used for parameter setting; the monitoring and testing module is used for installing and calibrating the first module; the status check alarm module is used for judging according to the number of alarms and performing on-site reset as needed.

[0015] A computer device comprises a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement a method for monitoring and controlling the inclination of a transmission line tower.

[0016] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of a transmission line tower inclination monitoring and control method.

[0017] Beneficial effects of the present invention: The transmission line tower tilt monitoring and control method provided by the present invention realizes real-time monitoring and early warning of the tower tilt state through six stages: initialization, testing, installation, inspection, judgment and reset. First, in the initialization stage, the intelligent terminal is connected to the monitoring module and the tilt alarm threshold is set, so that each module meets the standardization requirements, avoids false alarms or missed alarms, and ensures the accuracy of monitoring. Then in the test stage, the reliability of the module alarm function is verified one by one, the faulty module is eliminated, and the normal operation of subsequent monitoring is guaranteed. Through the decentralized installation of qualified modules, each tower is equipped with multiple monitoring modules, which improves the coverage and detection sensitivity of monitoring and ensures the accurate perception of the tower tilt state. In the inspection stage, the drone regularly patrols the line to take images and keep them in archives, which improves the inspection efficiency and data integrity, reduces the risk of manual inspection, and provides accurate records for subsequent analysis. On this basis, the system makes intelligent judgments based on the proportion of the number of alarm modules reaching two-thirds, simplifies the frequency of manual inspections, and makes the judgment of the tilt state more automated. Finally, through manual exploration and reset of the alarm module, the continuity and stability of the system after the tilt problem is handled are ensured, so that the monitoring module can quickly resume working state, and long-term monitoring is achieved. The present invention provides accurate and reliable monitoring and early warning of transmission line tower inclination through a complete monitoring and alarm mechanism, greatly improving the operational safety and maintenance efficiency of the transmission system.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0024] Example 1, reference Figure 1-Figure 3 , is an embodiment of the present invention, and provides a transmission line tower tilt monitoring and control method, comprising:

[0025] S1: Initialize and perform functional testing on the first module.

[0026] Furthermore, the transmission line tower tilt monitoring system includes a plurality of identical monitoring modules, each of which includes a strong magnet 1, a main control board 2, a photovoltaic panel 3, an electromagnet 4 and an outer casing 5;

[0027] The strong magnet 1 is mechanically connected and fixed to the main control board 2;

[0028] The main control panel 2 is electrically connected to the photovoltaic panel 3;

[0029] The photovoltaic panel 3 is embedded in the upper part of the outer shell box 5;

[0030] The electromagnet 4 is mechanically fixed to the side of the main control board 2;

[0031] The outer shell 5 can rotate 180° around the main control board 2;

[0032] The housing 5 can be mechanically fixed by the electromagnet 4 and cannot rotate around the main control board 2;

[0033] The main control board 2 includes a tilt sensor, a single-chip microcomputer, and a capacitive energy storage element;

[0034] The outer surface of the bottom of the outer shell box 5 is bright red.

[0035] It should be noted that the first module can be of multiple types, such as a monitoring module, a tilt sensor and Internet of Things (IoT) communication module, and a GNSS positioning monitoring based on satellite communication. In this embodiment, a monitoring module is used, the power of the monitoring module whose parameters are to be set is turned on, and the monitoring module enters the setting mode. A wireless connection is established with the monitoring module through a smart terminal device such as a computer or a mobile phone using a wireless transmission protocol such as Bluetooth, the configuration software is run, the tilt alarm action threshold of the monitoring module is set, and the power of the monitoring module is turned off.

[0036] Furthermore, in another feasible embodiment, the first module adopts a tilt sensor and an Internet of Things (IoT) communication module and GNSS positioning monitoring based on satellite communication, including a combination of a tilt sensor and an Internet of Things (IoT) communication module. A high-precision tilt sensor is combined with an Internet of Things (IoT) communication module to achieve real-time monitoring of the tilt state of the tower. The tilt sensor detects the angle change of the tower, and the IoT module transmits the data to the central server in real time through a cellular network (such as 4G / 5G). This solution utilizes the existing cellular communication network to achieve real-time, remote monitoring, which is suitable for more remote or complex environments, and remote monitoring and data analysis can be achieved through IoT platform management. Cellular networks rely on signal coverage, and when the signal is poor or the signal is interrupted, there will be problems with unstable data transmission. At the same time, the cost of this solution is relatively high, especially when large-scale deployment is required.

[0037] GNSS positioning monitoring based on satellite communication uses GNSS (Global Navigation Satellite System) positioning equipment to monitor the spatial displacement of the tower. By detecting the displacement changes of the tower in three-dimensional space, it is determined whether the tower has tilt or structural changes. The GNSS module sends data to the monitoring center via satellite communication. This solution does not rely on the ground network and is suitable for remote areas with complex terrain or far away from signal base stations. In addition, satellite monitoring can accurately grasp the overall displacement changes of the tower and achieve high-precision monitoring. The cost of satellite communication modules is high, and the accuracy of GNSS may be affected by factors such as weather and environmental occlusion, requiring complex algorithms to identify small tilt changes.

[0038] It should be noted that, hold the strong magnet part of the monitoring module to be tested, so that the photovoltaic panel faces upwards and keep it as horizontal as possible, then turn on the power of the monitoring module to put the monitoring module into working mode, and then tilt the monitoring module in any direction until the monitoring module alarms and the outer shell box is turned over, with the photovoltaic panel facing the ground and the red bottom of the outer shell facing upwards. This determines that the tested monitoring module is functioning normally. If the monitoring module still fails to alarm, it is determined to be a faulty module and needs to be repaired. All monitoring modules to be installed should be tested once.

[0039] S2: Install and calibrate the first module.

[0040] Furthermore, during this stage, the operator carries all the qualified monitoring modules to the work site, climbs the pole tower to be monitored, and tries to install the monitoring modules near the highest point of the pole tower. At least three monitoring modules are installed on each pole tower to be monitored, and the positions should be dispersed to ensure good lighting for the photovoltaic panels. During installation, the strong magnet of the monitoring module is reliably adsorbed on the iron structure of the pole tower, the power of the monitoring module is turned on, the monitoring module enters the working mode, and the reset button is pressed to make the monitoring module use the current photovoltaic panel plane as the reference horizontal plane to correct the inclination sensor measurement value.

[0041] It should be noted that when drones conduct regular line inspections, they must also observe the status of the monitoring modules on the pole towers, and record videos and take photos for archiving.

[0042] S3: Perform a first alarm determination based on the status check.

[0043] Furthermore, the first alarm judgment can be of multiple types, such as motion alarm judgment, tilt judgment based on optical image processing, and abnormal vibration analysis based on acceleration sensor. In this embodiment, the operator uses drone video recording and archived photos to check whether there is a monitoring module that has already triggered an alarm, that is, the outer shell of the monitoring module is flipped over so that the photovoltaic panel faces the ground and the red bottom plate faces the sky. If the number of monitoring modules that have triggered an alarm on a certain tower is not less than two-thirds of the total number of monitoring modules on the tower, the tower is determined to be suspected of tilting and enters the next stage. Otherwise, it returns to the drone line patrol observation monitoring module stage.

[0044] It should be noted that in another feasible embodiment, the first alarm judgment adopts tilt judgment based on optical image processing and abnormal vibration analysis based on acceleration sensor, including tilt judgment based on optical image processing, using a high-definition camera installed on the tower or inspection drone to regularly shoot and collect images of the tilt state of the tower. The morphological changes of the tower are analyzed by image processing algorithms (such as edge detection or deformation analysis) to determine whether there is tilt or abnormality. Optical image processing can provide intuitive tower tilt information and can complete the judgment without flipping the physical module. Image processing technology can also simultaneously check other external damage conditions of the tower to expand the monitoring function. This solution is greatly affected by environmental factors such as lighting, weather, and viewing angle, and it may be difficult to obtain clear images at night or in bad weather. In addition, the image processing system requires high computing power and the real-time performance may be slightly poor.

[0045] Based on the abnormal vibration analysis of the accelerometer, a high-precision accelerometer is integrated in the monitoring module, and the tilt state is judged by monitoring the acceleration changes of the tower in different directions. The change in gravity caused by the tilt will cause the output data of the accelerometer to be abnormal, so the tilt condition can be judged by the set acceleration threshold. The accelerometer is sensitive to tiny changes in physical tilt, can monitor state changes quickly and continuously, and does not rely on visual conditions, and is suitable for all-weather monitoring. This solution can achieve real-time alarm judgment. The accelerometer is sensitive to environmental vibrations. If there are external vibration sources such as wind or vehicles near the tower, it may cause false alarms. In addition, accurate measurement of the tilt angle requires precise calibration and algorithm support.

[0046] Furthermore, the operator uses professional tools to inspect the suspected tilted tower on site. After solving the suspected tilt problem of the tower, he climbs the tower and resets all monitoring modules that have triggered alarms, thus ending the entire process.

[0047] Embodiment 2, an embodiment of the present invention, provides a transmission line tower tilt monitoring and control method. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0048] First, this experiment uses an innovative transmission line tower tilt monitoring system to set up and test various monitoring modules and install them on the transmission tower to detect the tilt state of the tower and verify the reliability and response speed of the system. First, parameter initialization and functional testing are performed in a laboratory environment, and then qualified modules are installed in an outdoor experimental site to simulate the alarm monitoring process under the condition of tower tilt.

[0049] During the initialization phase of the monitoring module (S1 phase), first turn on the module power supply to put it into the setup mode. Use a laptop to connect to the monitoring module via Bluetooth and set the tilt alarm threshold through the configuration software. In the experiment, the threshold was set to 15 degrees to ensure that the module can effectively alarm when the tower tilt angle exceeds 15 degrees. After the configuration is completed, turn off the module power supply to put it into the waiting state.

[0050] Then the functional test (S2 stage) is carried out. The operator holds each module with the photovoltaic panel facing upward and keeping it horizontal. Turn on the module power and gradually tilt the module to the set alarm threshold to observe whether the module triggers the alarm and confirm that the box is turned over with the photovoltaic panel facing down and the red bottom facing up. After all modules have met the alarm requirements after the functional test, the unqualified modules are recorded as faulty modules and sent for repair, and the remaining qualified modules enter the installation stage.

[0051] During the installation phase (S3 phase), the operator brings qualified modules to the experimental site and selects three modules to be installed near the highest point of the tower, ensuring that the location of each module is dispersed and the lighting is good. During installation, strong magnets ensure that the modules are firmly attached to the iron components of the tower. After the power is turned on, the reset button is pressed to make the modules use the current plane of the photovoltaic panel as the reference horizontal plane to ensure the accuracy of the tilt sensor measurement.

[0052] Next comes the drone inspection phase (S4 phase), where the drone regularly inspects the lines and uses the camera function to observe the module status, record and photograph the flipping of each module. The drone operator archives the recorded content to provide reference data for subsequent analysis.

[0053] When the number of detection alarms reaches the threshold of two-thirds (stage S5), the system determines that the tower is suspected of tilting and arranges manual on-site exploration (stage S6). The operator climbs the tower to explore the suspected tilted area, confirms the tilt problem and handles it, and then resets all alarm modules to complete the entire experimental process.

[0054] Table 1 Experimental data table

[0055]

[0056] It can be seen from the data table that the monitoring module of the present invention can accurately respond to the inclination angle exceeding the threshold value under the setting of the 15-degree inclination alarm threshold value. For example, modules 1, 2, 4, 5 and 6 all exceeded the 15-degree threshold value under experimental conditions and triggered an alarm, while module 3 that did not reach the threshold value did not trigger an alarm, indicating that the alarm function of the monitoring system has good sensitivity and accuracy and can accurately identify the inclination exceeding the limit. In addition, all modules operate stably under the conditions of an installation height of 10 meters and a regular observation frequency of 7 days, ensuring the long-term monitoring capability and anti-interference capability of the system.

[0057] Compared with the traditional manual inspection method on the ground, the present invention can realize the automatic observation of regular inspection by drones and archive, which not only reduces the frequency of manual operation, but also reduces the detection missed rate. In particular, by reasonably setting the alarm threshold and regular observation cycle in the field exploration, it ensures timely response when the tower tilts. This efficient early warning mechanism greatly improves the safety of the transmission line. Traditional technology lags behind in real-time alarm and automatic detection, and there are safety hazards caused by the inability to monitor at high frequency. The present invention effectively reduces the false alarm rate and improves reliability through modular design and multi-point distributed monitoring.

[0058] Example 3, reference Figure 4 , which is an embodiment of the present invention, provides a transmission line tower tilt monitoring and control system, including an initialization module, a monitoring and testing module, and a status check alarm module.

[0059] The initialization module is used for parameter setting, the monitoring and testing module is used for installing and calibrating the first module, and the status check alarm module is used for making judgments based on the number of alarms and performing on-site reset as needed.
