Description

Technical Field

[0001] This invention relates to the field of pole tilt measurement technology, and in particular to the development of a pole tilt identification device for power distribution networks. Background Technology

[0002] As the core terminal link of the power system, the distribution network undertakes the critical task of directly supplying power to a large number of residential, industrial and commercial users. As the infrastructure supporting the distribution network lines, the structural stability of the power poles directly determines the reliability and security of the power grid. Distribution network operation and maintenance units need to conduct regular inspections and maintenance of facilities such as power poles, and monitor the tilt of the power poles in real time to prevent dangerous accidents such as pole collapse and line breakage caused by pole tilting, so as to ensure the stable operation of the power grid and the safety of people's lives and property.

[0003] However, current pole tilt monitoring in power distribution networks mainly relies on traditional manual inspection methods or existing monitoring devices. In practical applications, manual inspections depend entirely on the visual judgment and experience of inspectors, and are greatly affected by on-site lighting conditions, terrain, and subjective factors. The accuracy rate for identifying minor tilt hazards is only about 28%, easily overlooking slight tilts or misjudging the degree of tilt. Furthermore, manual inspections are difficult to conduct effectively at night, in strong winds, or during heavy rain, leading to undetected hazards. Statistics show that many pole collapse accidents in recent years have been caused by manual inspections failing to detect minor tilt hazards. Existing traditional pole tilt monitoring devices typically require... Drilling holes in cement or wooden poles using heavy tools such as electric drills and expansion bolts not only damages the pole's structure and reduces its mechanical strength, but also involves a cumbersome installation process, with an average installation time exceeding 30 minutes per unit. The high-altitude pole climbing operation poses significant safety risks, severely hindering the large-scale deployment and promotion of the equipment. Existing monitoring devices mostly use 4G or NB-IoT communication modules. In remote farmland, riverbanks, forest areas, and other areas with weak signal coverage, network congestion and signal attenuation lead to extremely high data transmission packet loss rates, resulting in warning information push delays generally exceeding 30 seconds, and even missed alarms. This fails to meet the technical requirements for real-time and reliable alarms for pole tilt exceeding limits. Therefore, we have developed a pole tilt identification device for power distribution networks. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: including an installation mechanism and an identification mechanism;

[0006] The installation mechanism is used to fix the identification mechanism to the outer wall of the power distribution pole.

The two insertion frames are symmetrically installed on both sides of the installation shell. A fixed channel is formed between the installation shell and the two insertion frames for the installation bandage to be inserted around and pass through.

[0007] The identification mechanism is detachably installed inside the mounting housing.

[0010] In a preferred embodiment, the MEMS tilt sensor is a dual-axis temperature-compensated MEMS tilt sensor. The MEMS tilt sensor is fixedly mounted at the center of the inner wall of the recognition frame via elastic shock-absorbing pads. The detection axis of the MEMS tilt sensor is parallel to the vertical central axis of the recognition frame. The recognition frame is composed of an upper shell and a lower shell, with an annular sealing groove at the joint between the upper and lower shells. A waterproof sealing ring is embedded in the annular sealing groove to achieve an IP67 protection rating for the recognition frame. The display screen is a dual-axis digital display screen, and the control buttons include a power switch button, a data switching button, and a reset button.

[0011] In a preferred embodiment, the circuit management board integrates a power management circuit and a 5G communication module. The power management circuit is electrically connected to the energy storage battery, the microcontroller (MCU), the MEMS tilt sensor, the display screen, and the audible and visual alarm module, respectively, to provide a stable operating voltage for each power-consuming module. The 5G communication module is bidirectionally connected to the microcontroller (MCU), and its external antenna extends to the outside through the top of the identification frame. A temperature sensor is also provided inside the identification frame, and the temperature sensor is connected to the microcontroller (MCU) to monitor the internal operating temperature of the identification mechanism and perform temperature drift compensation.

[0012] As a preferred implementation, it also includes a 5G communication module, a cloud server, and an operation and maintenance mobile terminal;

[0013] The microcontroller (MCU) inside the power distribution pole tilt identification device communicates with the cloud server through the 5G communication module, and the cloud server communicates with the operation and maintenance mobile terminal.

[0014] The system adopts a layered architecture design, consisting of a perception layer, a control layer, a transmission layer, a platform layer, and an application layer from bottom to top.

[0015] The sensing layer includes the MEMS tilt sensor, the audible and visual alarm module, and the display screen, which are used to collect raw data on the tilt angle of the power distribution network poles in real time and to provide local audible and visual warnings and numerical displays.

[0016] The control layer includes the microcontroller MCU and the power management module. The microcontroller MCU is used to receive the raw data collected by the sensing layer, execute the tilt threshold comparison algorithm, and generate control commands.

[0017] The transmission layer includes the 5G communication module, which is used to upload the early warning messages packaged by the microcontroller MCU to the platform layer through the 5G power dedicated slice network;

When the microcontroller (MCU) determines that the tilt angle collected by the MEMS tilt sensor exceeds a preset safety threshold, it controls the 5G communication module to immediately send multiple independent early warning messages continuously through the 5G channel. If the cloud server does not return a confirmation instruction within a preset time, the 5G communication module will automatically trigger a cyclic retransmission mechanism, retransmitting for a maximum of a preset number of rounds. The 5G communication module supports the MQTT lightweight protocol to reduce data transmission bandwidth usage in weak network environments.

[0022] In a preferred embodiment, the cloud server in the platform layer has a built-in message deduplication verification module and a data storage module. The message deduplication verification module is used to receive redundant early warning messages uploaded by the 5G communication module, perform hash comparison based on the message timestamp and device ID, filter duplicate alarm information, and generate a unique early warning event record. The data storage module is used to store the unique early warning event record and the regular tilt angle data periodically reported by the power distribution network pole tilt identification device, and generate a pole tilt change trend curve.

The operation and maintenance personnel send control commands to the cloud server through the mobile terminal. The cloud server sends the control commands sequentially through the transmission layer and the control layer to the power distribution network pole tilt identification device, so as to realize remote parameter configuration and reset operation to form a closed-loop management system.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0025] 1. This invention achieves quick, punch-free fastening by cleverly combining the installation mechanism and the identification mechanism, using interlocking frames and installation straps. Combined with an IP67-level waterproof sealing design and an internal shock-absorbing and heat dissipation layout, it achieves the beneficial effect of allowing a single person to complete a secure installation within 5 minutes without damaging the pole itself, and is able to withstand extreme outdoor weather conditions and ensure the long-term stable operation of internal components.

[0026] 2. This invention provides stable power to each module through the power management circuit on the circuit management board, and uses a dual-axis temperature-compensated MEMS tilt sensor to collect data in real time and process it with a microcontroller MCU. This achieves the beneficial effects of high-precision tilt quantization sensing, instant triggering of sound and light alarms and screen value refresh in local operation, and completely eliminates the omissions and misjudgments caused by manual visual inspection.

[0027] 3. This invention utilizes the multi-level early warning retransmission and weak network fault tolerance mechanism of the 5G communication module, combined with the message deduplication verification of the cloud server, to ultimately push accurate alarms to the operation and maintenance mobile terminal. This achieves the beneficial effect of zero missed alarms and zero delays in remote weak network environments, and realizes the full-link digital closed-loop management of "perception-transmission-analysis-handling".

[0042] The development of a pole tilt identification device for power distribution networks provided by this invention will now be described.

[0043] Example 1

[0044] like Figure 1 As shown in Figure 3, the present invention provides a technical solution: the development of a pole tilt identification device for power distribution networks, comprising an installation mechanism 1 and an identification mechanism 2;

[0045] The installation mechanism 1 is used to fix the identification mechanism 2 to the outer wall of the power distribution pole. The installation mechanism 1 includes an installation housing 11, two through frames 12 and an installation bandage 13. The two through frames 12 are symmetrically installed on both sides of the installation housing 11. A fixed channel is formed between the installation housing 11 and the two through frames 12 for the installation bandage 13 to be inserted around. The installation bandage 13 is inserted around the power distribution pole and into the fixed channel to achieve the hole-free clamp fixation of the installation mechanism 1.

[0046] The identification mechanism 2 is detachably installed inside the mounting housing 11. The identification mechanism 2 includes an identification frame 21, a display screen 22, a control button 23, a MEMS tilt sensor 24, a microcontroller MCU 25, an energy storage battery 26, a circuit management board 27, and a mounting isolation frame 28. The identification frame 21 is fixedly installed in the inner cavity of the mounting housing 11, the mounting isolation frame 28 is fixedly installed inside the identification frame 21, the circuit management board 27 is installed between the energy storage battery 26 and the mounting isolation frame 28, the microcontroller MCU 25 is mated to one end of the energy storage battery 26, one end of the MEMS tilt sensor 24 is mated to the inner wall of the identification frame 21, the display screen 22 is embedded in the front panel of the identification frame 21, and the control button 23 is installed on the identification frame 21 and located at the bottom of the display screen 22. The MEMS tilt sensor 24, the display screen 22, and the control button 23 are all electrically connected to the microcontroller MCU 25.

[0047] The mounting housing 11 has mating grooves on both sides that are adapted to the insertion frame 12. The insertion frame 12 is slidably connected to the mounting housing 11 through the mating grooves. The outer side wall of the insertion frame 12 is provided with a buckle locking device for locking the mounting bandage 13. The mounting bandage 13 is made of corrosion-resistant polyester material. The inner surface of the mounting bandage 13 is evenly covered with anti-slip rubber cushioning pads. The surface of the anti-slip rubber cushioning pads is provided with anti-slip textures to increase friction. The bottom of the inner cavity of the mounting housing 11 is provided with a shock-absorbing pad layer for supporting the identification mechanism 2. The top of the mounting housing 11 is provided with a transparent protective cover for protecting the display screen 22.

[0048] The mounting bracket 28 includes a base and multiple spaced support columns. The top of the support columns has threaded holes for fixing the circuit management board 27. The circuit management board 27 is mounted on the support columns with fasteners, and a heat dissipation gap is reserved between the circuit management board 27 and the energy storage battery 26. The energy storage battery 26 is a high-capacity lithium battery. The energy storage battery 26 is wrapped with an insulating and heat-insulating sleeve. The microcontroller MCU 25 is connected to one end of the energy storage battery 26 through a ribbon cable socket. The bottom of the microcontroller MCU 25 has conductive contacts that are electrically connected to the circuit management board 27.

[0049] MEMS tilt sensor 24 is a dual-axis temperature-compensated MEMS tilt sensor. MEMS tilt sensor 24 is fixedly installed at the center of the inner side wall of recognition frame 21 by elastic shock-absorbing rubber pads. The detection axis of MEMS tilt sensor 24 is parallel to the vertical central axis of recognition frame 21. Recognition frame 21 is spliced ​​from upper shell and lower shell. The joint between upper shell and lower shell is provided with an annular sealing groove. A waterproof sealing ring is embedded in the annular sealing groove to make recognition frame 21 achieve IP67 protection level. Display screen 22 is a dual-axis digital display screen. Control buttons 23 include power switch button, data switching button and reset button.

[0050] In this embodiment, through the clever cooperation between the installation mechanism 1 and the identification mechanism 2, the insertion frame 12 and the installation bandage 13 are used to achieve quick fixation without drilling. Combined with the IP67-level sealing and waterproof design and the internal shock absorption and heat dissipation layout, it achieves the beneficial effect that a single person can complete the firm installation within 5 minutes without damaging the pole body, and can withstand extreme outdoor weather and ensure the long-term stable operation of internal components.

[0051] Example 2

[0052] like Figure 1 As shown in Figure 5, the circuit management board 27 integrates a power management circuit and a 5G communication module. The power management circuit is electrically connected to the energy storage battery 26, the microcontroller MCU 25, the MEMS tilt sensor 24, the display screen 22, and the audible and visual alarm module, respectively, to provide a stable operating voltage for each power-consuming module. The 5G communication module is bidirectionally connected to the microcontroller MCU 25, and the external antenna of the 5G communication module extends to the outside through the top of the identification frame 21. The identification frame 21 is also equipped with a temperature sensor, which is connected to the microcontroller MCU 25, to monitor the internal operating temperature of the identification mechanism 2 and perform temperature drift compensation.

[0053] The microcontroller MCU25 in the control layer is electrically connected to each module in the sensing layer. Specifically, the data input terminal of the microcontroller MCU25 is connected to the data output terminal of the MEMS tilt sensor 24 to obtain dual-axis tilt data; the first data output terminal of the microcontroller MCU25 is connected to the display screen 22 to send display commands to refresh the tilt angle value in real time; the second data output terminal of the microcontroller MCU25 is connected to the audible and visual alarm module to send alarm commands to trigger a local audible and visual alarm when the tilt angle exceeds the safety threshold; and the power management module is electrically connected to the microcontroller MCU25, the MEMS tilt sensor 24, the display screen 22, and the audible and visual alarm module to provide stable power supply.

[0054] In this embodiment, the power management circuit on the line management board 27 provides stable power to each module, and the dual-axis temperature-compensated MEMS tilt sensor 24 collects data in real time and sends it to the microcontroller MCU 25 for processing. This achieves the beneficial effects of high-precision tilt quantization perception, instant triggering of sound and light alarms and screen value refresh in local operation, and completely eliminates the omissions and misjudgments caused by manual visual inspection.

[0055] Example 3

[0056] like Figure 1 As shown in Figure 5, it also includes a 5G communication module, a cloud server, and a mobile terminal for operation and maintenance.

[0057] The microcontroller MCU25 inside the power distribution network pole tilt identification device communicates with the cloud server via a 5G communication module, and the cloud server communicates with the operation and maintenance mobile terminal.

[0058] The system adopts a layered architecture design, consisting of the perception layer, control layer, transmission layer, platform layer, and application layer from bottom to top.

[0059] The sensing layer includes a MEMS tilt sensor 24, an audible and visual alarm module, and a display screen 22, which are used to collect raw data on the tilt angle of the power distribution network poles in real time and to provide local audible and visual warnings and numerical displays.

[0060] The control layer includes a microcontroller MCU25 and a power management module. The microcontroller MCU25 is used to receive the raw data collected by the sensing layer, execute the tilt threshold comparison algorithm, and generate control commands.

[0061] The transport layer includes a 5G communication module, which is used to upload the warning messages packaged by the microcontroller MCU25 to the platform layer through the 5G power dedicated slice network;

[0062] The platform layer includes cloud servers, which are used to receive early warning messages, perform message deduplication verification, and perform data analysis and storage.

[0063] The application layer includes operation and maintenance mobile terminals, which are used to receive and display the final warning information pushed by the cloud server;

[0064] The 5G communication module in the transport layer has a built-in multi-level early warning retransmission and weak network fault tolerance mechanism. When the microcontroller MCU25 determines that the tilt angle collected by the MEMS tilt sensor 24 exceeds the preset safety threshold, it controls the 5G communication module to immediately send multiple independent early warning messages continuously through the 5G channel. If the cloud server does not return a receipt confirmation instruction within a preset time, the 5G communication module will automatically trigger the cyclic retransmission mechanism, which can retransmit in a maximum of a preset number of rounds. The 5G communication module supports the MQTT lightweight protocol, which can reduce the data transmission bandwidth consumption in weak network environments.

[0065] The cloud server in the platform layer has a built-in message deduplication verification module and a data storage module. The message deduplication verification module is used to receive redundant early warning messages uploaded by the 5G communication module, perform hash comparison based on the message timestamp and device ID, filter duplicate alarm information, and generate a unique early warning event record. The data storage module is used to store the unique early warning event record and the regular tilt angle data periodically reported by the power distribution network pole tilt identification device, and generate a pole tilt change trend curve.

[0066] The operation and maintenance mobile terminal in the application layer is a smartphone or tablet, which is equipped with an operation and maintenance management APP. The cloud server records and sends the unique early warning event to the operation and maintenance mobile terminal through alarm push. The operation and maintenance management APP displays the geographical location, tilt angle, tilt trend curve and power status of the alarm pole in real time. The operation and maintenance personnel send control commands to the cloud server through the operation and maintenance mobile terminal. The cloud server sends the control commands to the distribution network pole tilt identification device through the transmission layer and control layer in sequence, so as to realize remote parameter configuration and reset operation to form a closed-loop management system.

[0067] In this embodiment, through the multi-level early warning re-issuance and weak network fault tolerance mechanism of the 5G communication module, combined with the message deduplication verification of the cloud server, the accurate alarm is finally pushed to the operation and maintenance mobile terminal, achieving the beneficial effect of zero missed alarms and zero delays in remote weak network environments, and realizing the full-link digital closed-loop management of "perception-transmission-analysis-handling".

[0068] Working principle:

[0069] like Figure 1 As shown in Figure 5, in actual use, the installation and physical sensing stage is carried out first. The operator fixes the installation mechanism 1 to the outer wall of the power distribution pole. Specifically, the installation bandage 13 is wrapped around the pole and inserted between the insertion frames 12 on both sides of the installation sleeve 11. The buckle is tightened to complete the non-drilling and non-destructive fixing. After the device is fixed, the MEMS tilt sensor 24 inside the recognition frame 21 is tightly attached to the pole body through the elastic shock-absorbing rubber pad, which senses the original data of the pole's dual-axis tilt angle in real time and transmits the data to the microcontroller MCU 25. At the same time, the installation of the isolation frame 28 and the line management board 27 ensures the heat dissipation and physical isolation of the internal energy storage battery 26 and each circuit board, ensuring the structural stability of the equipment under complex outdoor working conditions.

[0070] Subsequently, the local processing and weak network transmission phase begins. After receiving data from the MEMS tilt sensor 24, the microcontroller MCU25 immediately executes the tilt threshold comparison algorithm. If the tilt angle exceeds the safety threshold, it sends a display command to the display screen 22 to refresh the value and sends an alarm command to the audible and visual alarm module to trigger a local alarm. On the other hand, the microcontroller MCU25 transmits the packaged early warning message to the 5G communication module on the line management board 27. In weak network environments such as remote forest areas, if the 5G communication module does not receive a confirmation command from the cloud, it will automatically trigger a three-level cyclic retransmission fault tolerance mechanism to continuously send multiple independent early warning messages, preventing missed reports and delays caused by data packet loss.

[0071] Finally, in the cloud-based deduplication and closed-loop processing stage, after the redundant early warning messages uploaded by the 5G communication module reach the cloud server, the built-in message deduplication verification module performs hash comparison based on the timestamp and device ID, automatically filters duplicate alarms, generates a unique early warning event record and stores it. The cloud server pushes the final early warning information to the operation and maintenance mobile terminal through alarm push. The operation and maintenance personnel can view the tilt trend and power status in real time through the terminal APP, and can remotely issue reset or parameter configuration commands. The commands are sent down to the microcontroller MCU25 through the transmission layer and control layer, thus forming a complete closed-loop management system from accurate front-end perception and stable transmission to intelligent back-end analysis and remote processing.
