Description

Technical Field

[0001] This invention relates to the field of pole and tower technology, specifically to a pole and tower tilt monitoring system based on a dual-antenna approach. Background Technology

[0002] A power transmission line pole is a pole-shaped or tower-shaped structure that supports the overhead transmission line conductors and overhead ground wires and maintains a certain distance between them and the ground. Power transmission line poles play an important role in the safe operation of the power system. However, there are many uncertainties and external interference factors in the pole structure. Over time, uneven foundation settlement, self-deformation, external tension, wind, other geological disasters, and even external damage can cause the pole's own structure or connection with the foundation to become unstable, leading to the pole tilting or even collapsing, which affects power transmission.

[0003] Currently, the tilt detection of towers is generally carried out manually on-site. This method increases the workload of staff and cannot provide multi-level tilt warnings when the tower is tilting. Furthermore, manual detection may result in inaccurate data due to human negligence. To address these issues, a tower tilt monitoring system based on a dual-antenna approach was designed.

[0004] Furthermore, existing antenna designs typically lack sufficient protection to prevent rainwater from directly washing over the antenna. Prolonged rain can cause corrosion or other forms of physical damage to the antenna surface. Because the antenna is directly exposed to rain and dust, it requires frequent cleaning and maintenance to maintain its performance. This not only increases operating costs but may also temporarily render the antenna unusable during maintenance. Simultaneously, the accumulation of rainwater and dust can affect the antenna's signal reception capabilities, leading to a decline in signal quality and impacting overall communication efficiency and accuracy; therefore, improvements are also necessary. Summary of the Invention

[0005] The purpose of this invention is to provide a pole tilt monitoring system based on a dual-antenna approach, in order to solve the problem that existing pole tilt detection is generally carried out manually, which not only increases the workload of staff, but also makes the data easily erroneous due to oversight, and makes it impossible to provide staff with multi-level tilt warnings when the pole tilts.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A tower tilt monitoring system based on a dual-antenna approach includes a set of two RTK antennas, a monitoring module, a monitoring center, a base station, a detection module, and a solar power supply system; the RTK antenna, i.e., a GNSS-RTK antenna, is used to receive satellite signals.

[0008] The monitoring module includes a computing unit, a wind / rain sensor, an environmental sensor, an equipment operating status acquisition unit, a data storage unit, and a 4G module. The computing unit calculates the data received by the RTK antenna, using the carrier phase difference and related equations from different satellites received by the dual antennas, combined with the angle between the baseline of the dual antennas and the "true north" direction, to obtain the tilt angle of the tower and obtain the tilt value. The wind / rain sensor and environmental sensor detect the tower environment and obtain external environmental data. The equipment operating status acquisition unit collects information on the operating status of each device and obtains external device operating status parameters. The data storage unit stores the data. The 4G module transmits the obtained tilt value, external environmental data, and external device operating status parameters to the monitoring center via 4G transmission.

[0009] The monitoring center includes display devices, input devices, a server host, a receiving unit, a storage device, and a command host. The display devices display the data parameters received by the server host and the calculated predicted trend line. The input devices control the server host. The server host has built-in monitoring platform software that summarizes and statistically analyzes received tilt values, high-precision positioning values, external environment data, and external device operating status parameters, and refers to historical data stored in the storage (i.e., data statistics under normal conditions) to calculate the predicted trend line. The receiving unit receives and transmits externally transmitted data to the server host and storage unit. The storage unit stores the received data, and the stored historical data can be accessed by the server host. The command host, based on the trend of the predicted trend line, can control remote devices to issue first-level warnings, second-level warnings, or remain inactive.

[0010] A reference station is a ground station used to provide precise coordinates or high-precision differential positioning services. It can receive satellite signals and process data to obtain high-precision positioning values.

[0011] The detection module is used to perform position change early warning detection on the base station;

[0012] A solar power supply system is used to power the monitoring module, detection module, and base station.

[0013] The above-mentioned tower tilt monitoring system based on dual antennas is equipped with an automatic protection device, including a main body and an RTK antenna installed on the top surface of the main body. A motor is fixedly installed on the surface of the main body, and a pulley A is installed at the output end of the motor. A rotating rod is rotatably connected to the top surface of the main body, and a pulley B is fixedly installed on the surface of the rotating rod. A baffle plate is fixedly installed at the top of the rotating rod, and a transmission belt is fitted on the surface of pulley A and pulley B.

[0014] In the above-mentioned tower tilt monitoring system based on dual antennas, the lower end face of the detection end is higher than the base of the reference station, a gap is left between the pressing rod and the base of the reference station, a gap is left between the transmission rod and the contact button, and the contact button is electrically connected to the signal transmitter.

[0015] The monitoring module is installed on the upper part of the tower, and the RTK antennas are all installed in the upper middle part of the tower. A large gap needs to be left between two RTK antennas in a set.

[0016] In the aforementioned tower tilt monitoring system based on a dual-antenna method, the shielding plate is made of PP plastic.

[0017] The aforementioned tower tilt monitoring system based on dual antennas has flow guide grooves on its surface, and these flow guide grooves are arranged at equal intervals on the surface of the main body.

[0018] The aforementioned tower tilt monitoring system based on dual antennas has chamfered edges on its main body, with the chamfers evenly distributed at the four corners of the main body's surface.

[0019] The aforementioned tower tilt monitoring system based on dual antennas has a support adjustment mechanism on the bottom surface of the main body. The support adjustment mechanism includes a mounting plate, which is fixedly installed on the bottom surface of the main body. An extension plate is slidably connected inside the mounting plate. A support rod is fixedly installed on the bottom surface of the extension plate. A bottom block is fixedly installed on the side of the extension plate. A top block is fixedly installed on the side of the mounting plate. A threaded rod is rotatably connected to the top surface of the bottom block.

[0020] In the aforementioned tower tilt monitoring system based on a dual-antenna method, the top block has internal threads that mesh with a threaded rod.

[0021] In the aforementioned tower tilt monitoring system based on a dual-antenna method, the top end of the threaded rod is connected to an adjustment motor mounted on the top block, and the adjustment motor is a stepper motor.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention comprises an RTK antenna, a monitoring module, a monitoring center, a base station, a detection module, and a solar power supply system. The solar power supply system provides power to the electrical equipment. Satellite signals received by the dual RTK antennas are processed by the monitoring module to obtain tilt values. Wind / rain sensors and environmental sensors in the monitoring module monitor the environment of the tower, obtaining environmental data. The equipment operating status acquisition unit collects information on the operating status of each device, obtaining equipment operating status parameters. The base station receives satellite signals and processes the data to obtain high-precision positioning values. Finally, the server host in the monitoring center uses monitoring platform software to summarize and statistically analyze the received tilt values, high-precision positioning values, external environmental data, and external equipment operating status parameters. Referring to historical data stored in the database (i.e., data statistics under normal conditions), a predicted trend line is obtained after calculation. Based on the trend of the predicted trend line, the command host can control the remote devices to issue first-level warnings, second-level warnings, or inaction. The detection module can detect position changes at the base station and issue a warning to the monitoring center when the base station shows significant tilt, ensuring the accuracy of the high-precision positioning values ​​used. The pole tilt monitoring system based on dual antennas of the present invention can automatically detect the tilt of poles and provide multi-level early warnings. It solves the problem that the existing pole tilt detection is generally carried out manually, which not only increases the workload of staff, but also makes the data easy to be erroneous due to oversight, and it is impossible to provide multi-level tilt warnings to staff when the pole is tilted.

[0024] Furthermore, this invention uses an automatic shield to cover the RTK antenna in rainy weather, preventing rainwater from directly contacting the antenna surface and avoiding corrosion and damage caused by direct rainwater erosion, thereby extending the antenna's lifespan. Also, because the RTK antenna is protected, damage caused by environmental factors such as rainwater and dust that may remain after rainwater evaporates is reduced, decreasing the need for regular antenna maintenance and cleaning, thus lowering maintenance costs.

[0034] Please see Figure 1-6 , the present invention provides a technical solution:

[0035] A tower tilt monitoring system based on dual RTK antennas includes a set of two RTK antennas, a monitoring module, a monitoring center, a base station 18, a detection module 19, and a solar power supply system; the RTK antenna, i.e., the GNSS-RTK antenna, is used to receive satellite signals;

[0036] The monitoring module includes a computing unit, wind / rain sensors, environmental sensors, an equipment operating status acquisition unit, a data storage unit, and a 4G module. The computing unit calculates the data received by the RTK antenna, using the carrier phase difference and related equations from different satellites received by the dual RTK antennas, combined with the angle between the baseline of the dual RTK antennas and the "true north" direction, to obtain the tower's tilt angle and thus the tilt value. The wind / rain sensors and environmental sensors detect the tower environment and obtain external environmental data. The equipment operating status acquisition unit collects information on the operating status of each device, obtaining external device operating status parameters. The data storage unit stores the data. The 4G module transmits the obtained tilt value, external environmental data, and external device operating status parameters to the monitoring center via 4G transmission.

[0037] The monitoring center includes display devices, input devices, a server host, receiving units, storage devices, and a command host. The display devices show the data parameters received by the server host and the resulting predicted trend line. The input devices control the server host. The server host has built-in monitoring platform software that summarizes and statistically analyzes received tilt values, high-precision positioning values, external environmental data, and external device operating status parameters. It also references historical data stored in the storage, i.e., data statistics under normal conditions, and calculates the predicted trend line. The receiving units receive and transmit externally transmitted data to the server host and storage units. The storage units store the received data, and the stored historical data can be accessed by the server host. The command host, based on the trend of the predicted trend line, can control remote devices to issue first-level warnings, second-level warnings, or remain inactive.

[0038] Reference station 18 is a ground station used to provide precise coordinates or high-precision differential positioning services. It can receive satellite signals and process data to obtain high-precision positioning values.

[0039] Detection module 19 is used to perform position change early warning detection on base station 18;

[0040] A solar power supply system is used to power the monitoring module, the detection module 19, and the base station 18.

[0041] The detection module 19 is installed on the outside of the pole of the reference station 18. The detection module 19 includes a support plate 19-1 fixed on the outside of the reference station 18. A set of multiple detection ends 19-3 arranged at equal angles are fixedly connected to the lower side of the support plate 19-1. The detection end 19-3 includes a sleeve 231. A pressing rod 232 is slidably connected in the lower hole of the sleeve 231. A transmission rod 233 is fixedly connected to the upper side of the pressing rod 232. A spring 234 sleeved on the outside of the transmission rod 233 is fixedly connected to the upper side of the pressing rod 232. The upper end of the spring 234 is fixedly connected to the top inner wall of the sleeve 231. A contact button 235 located inside the spring 234 is installed on the top inner wall of the sleeve 231. A signal transmitter 19-4 is installed on the upper side of the support plate 19-1. A protective shell 19-2 sleeved on the outside of the set of detection ends 19-3 is fixedly connected to the lower side of the support plate 19-1. This configuration enables the detection module 2 to perform early warning detection of position changes in the base station 18. When the base station 18 experiences a significant tilt, it can issue an early warning to the monitoring center to ensure the accuracy of the high-precision positioning values ​​used. When the base station 18 is significantly tilted due to an external impact, the detection end 19-3 on the other side of the impact point will contact the ground. This causes the pressure rod 232 to be squeezed by the ground, driving the transmission rod 233 upward and activating the contact button 235. The contact button 235 controls the signal transmitter 19-4 to send an alarm message to the display device in the monitoring center, indicating that the base station 18 has tilted and that the high-precision positioning value emitted by the base station 18 is unreliable. The lower end of the detection end 19-3 is higher than the base of the reference station 18. A gap is maintained between the pressure rod 232 and the base of the reference station 18. This design ensures that the pressure rod 232 is normally not in contact with the ground. A gap is also maintained between the transmission rod 233 and the contact button 235. This design ensures that the transmission rod 233 is normally not in contact with the contact button 235. All contact buttons 235 are electrically connected to the signal transmitter 19-4, allowing the contact button 235 to control the signal transmitter 19-4 to send signals. The monitoring module is installed at the top of the tower, and the RTK antennas are all installed in the upper-middle part of the tower. A large gap is required between two RTK antennas in a group, allowing the dual RTK antennas to receive signals from different locations.

[0042] Workflow: The operation steps of the pole tilt monitoring system based on dual RTK antennas are as follows: Note 1: The solar power supply system can power all electrical equipment; Note 2: The detection module 19 can perform early warning detection of position changes in the base station 18. When the base station 18 itself experiences a significant tilt, it can issue an early warning to the monitoring center to ensure the accuracy of the high-precision positioning values ​​used. When the base station 18 is significantly tilted due to external impact, the detection end 19-3 on the other side of the impact location will contact the ground, causing the pressure rod 232 to be squeezed by the ground, driving the transmission rod 233 to move upward and activate the contact button 235. Through the contact button 235, the signal transmitter 19-4 can be controlled to send an alarm message to the display device in the monitoring center, indicating that the base station 18 has tilted and the high-precision positioning value issued by the base station 18 is unreliable, requiring maintenance by personnel. First, the satellite signals received by the dual RTK antennas are processed by the computing unit of the monitoring module (using the carrier phase difference and related equations of different satellites received by the dual RTK antennas, combined with the angle between the baseline of the dual RTK antennas and the "true north" direction, to obtain the tilt angle of the tower), thus obtaining the tilt value. The wind / rain sensor and environmental sensor of the monitoring module can detect the tower environment and obtain external environmental data. The equipment working status acquisition unit can collect information on the working status of each device and obtain external equipment working status parameters. The base station 18 can provide precise coordinates or high-precision differential positioning services, receive satellite signals and process data to obtain high-precision positioning values. Finally, the server host of the monitoring center, through the monitoring platform software, can summarize and statistically analyze the received tilt value, high-precision positioning value, external environmental data, and external equipment working status parameters, and refer to the historical data stored in the storage, i.e., the data statistics under normal conditions, to obtain a predicted trend line after calculation. Based on the trend of the predicted trend line, the command host can control the remote devices to issue first-level warnings, second-level warnings, or no action. The first-level early warning refers to the control of the monitoring module's devices to switch from low power consumption to standard operating status to increase data acquisition density, while simultaneously activating the audible and visual alarms on the towers. The second-level early warning refers to the timely implementation of power transmission control and diversion measures, notifying emergency response departments to handle the emergency, enabling the tower tilt monitoring system based on dual RTK antennas to automatically detect tower tilt and provide multi-level early warnings.

[0043] See Figure 7 and Figure 8This invention provides an automatic protection device, including a body 1. An RTK antenna 2 is fixedly mounted on the top surface of the body 1, and the antenna can be fixed with bolts to enhance structural stability. A motor 3 is fixedly mounted on the surface of the body 1, and a pulley A4 is mounted on the output end of the motor 3. The pulley A4 can be keyed or press-fitted, which ensures accuracy and reliability during transmission. A rotating rod 5 is rotatably connected to the top surface of the body 1. The rotating rod 5 can be supported by bearings or sliding, which reduces friction and improves movement efficiency during rotation. A pulley B6 is fixedly mounted on the surface of the rotating rod 5, and a transmission belt 8 is fitted between the rotating rod 5 and the pulley A4. This transmission belt 8 can be a synchronous belt or a V-belt, providing good transmission efficiency and small transmission error.

[0044] In addition, a baffle plate 7 is fixedly installed at the top of the rotating rod 5. The baffle plate 7 is made of PP plastic, which is not only lightweight but also has good corrosion resistance, making it suitable for outdoor use. A transmission belt 8 is fitted onto the surfaces of pulleys A4 and B6. The selection of the transmission belt 8 can be customized according to the load size and transmission distance to ensure transmission stability and efficiency. A guide groove 9 is formed on the surface of the main body 1, and the guide grooves 9 are evenly spaced on the surface of the main body 1. This design can effectively reduce the wind resistance of the device and prevent damage to the machine body due to wind resistance when the wind force is high. Chamfers 10 are formed at the corners of the main body 1, and the chamfers 10 are evenly distributed at the four corners of the surface of the main body 1. This design is not only aesthetically pleasing but also prevents injury caused by sharp edges during operation.

[0045] In addition, a support adjustment mechanism is provided on the bottom surface of the main body 1. The support adjustment mechanism includes a mounting plate 11, which is fixedly installed on the bottom surface of the main body 1 by bolting or welding. These methods ensure the stability and durability of the structure. An extension plate 12 is slidably connected inside the mounting plate 11. This sliding connection can be achieved by a slide rail or ball screw, allowing the extension plate 12 to slide smoothly during adjustment and increasing the flexibility of the equipment. A support rod 13 is fixedly installed on the bottom surface of the extension plate 12 by bolting or welding to ensure the stability of the support rod 13 under load. A base block 14 is fixedly installed on the side of the extension plate 12, which can also be fixed by bolting or welding to ensure a strong connection. A top block 15 is fixedly installed on the side of the mounting plate 11. The top block 15 has internal threads that mesh with a threaded rod 16. The threaded connection provides an adjustable structure, making operation more precise and convenient. The top surface of the base block 14 is rotatably connected to the threaded rod 16. The rotatable connection can be achieved by bearings or sleeves, allowing the threaded rod 16 to rotate smoothly, thereby adjusting the height or position of the structure. The top end of the threaded rod 16 is connected to an adjusting motor 17 mounted on the top block 15. The adjusting motor 17 is a stepper motor. The adjusting motor works in conjunction with an electronic level 20 mounted on the main body 1 to adjust the posture of the main body 1, preventing inaccurate measurement due to the tilt of the main body 1.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
