Description

A method, system, equipment, and medium for linking a power pole overturning early warning and buffer device. Technical Field

[0001] This invention relates to the field of safety monitoring technology, specifically to a method, system, equipment, and medium for linking a power pole overturning early warning and buffer device. Background Technology

[0002] With the rapid development of power systems, utility poles, as crucial supporting facilities for power distribution networks, are directly related to the reliability of power supply and the safety of workers. Especially during pole work, in severe weather conditions, or during foundation settlement, utility poles face the risk of overturning. Existing utility pole protection technologies have the following shortcomings: Traditional pole protection measures mainly improve pole stability through passive methods such as adding guy wires and reinforcing the foundation, or by using purely mechanical buffer devices to mitigate the impact after overturning. These methods cannot provide early warning signals in the early stages of overturning. In actual operation, the overturning of a utility pole is often a gradual process, potentially lasting from a slight initial tilt to final collapse, which may take several seconds or even tens of seconds.

[0003] On-site workers primarily rely on visual observation to determine the stability of utility poles. This qualitative assessment is heavily influenced by subjective factors and cannot detect minute changes in tilt. Some engineering practices use plumb lines to check pole verticality, but this method only allows for static testing before work begins and cannot monitor dynamic changes in the pole's condition during operation. When workers move the pole, apply external forces, or encounter sudden wind loads, the pole's stress state changes, and the tilt angle may increase rapidly. Current technology cannot detect these changes in a timely manner.

[0004] Some advanced work sites are equipped with simple tilt alarm devices, but these alarms are mostly limited to single sound or light signals and are only applicable to on-site situations. When workers on the pole are focused on their tasks, they are likely to overlook these alarm signals. Furthermore, existing devices lack an information linkage mechanism with ground monitoring personnel, preventing them from being promptly informed of any abnormalities on the pole and thus hindering their ability to organize rescue efforts or direct evacuation in a timely manner. Summary of the Invention

[0005] In view of the above-mentioned problems, the present invention provides a method, system, device and medium for linking a power pole overturning warning and a buffer device.

[0006] Therefore, the technical problem solved by this invention is that: relying solely on tilt angle thresholds for judgment is easily affected by wind vibration and other interferences, resulting in false alarms; frequent flashing of warning signals affects the judgment of operators; and the warning and buffer devices do not form a linkage mechanism, resulting in limited protection effect.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for linking a utility pole overturning early warning and buffer device, comprising: acquiring zero-point reference angles of multiple monitoring axes when the utility pole is in an upright state; collecting tilt angle data of the multiple monitoring axes in real time, filtering the collected tilt angle data to obtain effective tilt angle values, and calculating the current composite tilt angle based on the zero-point reference angles and the effective tilt angle values; acquiring multiple composite tilt angles within a preset time window, and calculating tilt change characteristic quantities based on the composite tilt angles corresponding to the first and last moments of the time window; and determining the early warning level using a multi-level judgment strategy based on the composite tilt angles and the tilt change characteristic quantities, wherein the multi-level judgment strategy includes a first early warning level and a second early warning level, wherein the triggering conditions for the first early warning level include... The second warning level is triggered when the composite tilt angle exceeds the first threshold and the tilt change characteristic exceeds the change threshold. The alarm device outputs a corresponding alarm signal according to the warning level. When the warning level reaches the second warning level, alarm information is sent to the receiving terminal via wireless communication. When the utility pole overturns, the buffer device responds with the overturning movement. The buffer device includes an elastic buffer structure arranged along an arc trajectory. The compression deformation of the elastic buffer structure absorbs the torque generated by the overturning. When the compression stroke of the elastic buffer structure reaches a preset limit value, a linkage signal is triggered to adjust the warning level. When the warning level is triggered, the tilt angle data, the warning level, and the status of the buffer device during the warning event are recorded.

[0008] As a preferred embodiment of the method for linking a pole tilting warning and a buffer device according to the present invention, the step of filtering the collected tilt angle data includes: maintaining a data buffer of a preset length, the data buffer being used to store multiple continuously collected tilt angle data; adding newly collected tilt angle data to the data buffer and removing the earliest tilt angle data from the data buffer; calculating the average value of all tilt angle data in the data buffer as the effective tilt angle value.

[0009] As a preferred embodiment of the method for linking a pole overturning warning and a buffer device according to the present invention, the calculation of the tilt change characteristic quantity based on the composite tilt angle corresponding to the beginning and end times of the time window includes: grouping multiple composite tilt angles within the time window according to time sequence to obtain several composite tilt angles in the starting period and several composite tilt angles in the ending period; performing statistical processing on the several composite tilt angles in the starting period and several composite tilt angles in the ending period respectively to obtain the starting tilt angle characteristic value and the ending tilt angle characteristic value; and calculating the tilt change characteristic quantity based on the change relationship between the starting tilt angle characteristic value and the ending tilt angle characteristic value.

[0010] The beneficial effects of this preferred technical solution are as follows: By grouping and statistically processing the tilt angle data within a time window, extracting the characteristic values ​​of the start and end segments, and calculating the change relationship, the dynamic trend of pole tilt can be accurately reflected. Compared with single-measurement judgment, this method effectively eliminates the influence of instantaneous interference and measurement fluctuations, avoiding false alarms triggered by accidental factors such as wind vibration and construction vibration. Simultaneously, the judgment based on the change relationship can distinguish between static tilting and dynamic overturning processes, improving the pertinence and reliability of early warnings and reducing the number of interruptions in on-site operations.

[0011] As a preferred embodiment of the method for linking a pole overturning warning and a buffer device according to the present invention, the method of determining the warning level using a multi-level judgment strategy includes: after triggering the warning, continuously monitoring the composite tilt angle and the tilt change characteristic quantity; determining whether the release requirements are met according to the preset warning release conditions; and releasing the current warning level when the warning release conditions are met and the duration reaches the preset holding time.

[0012] The beneficial effects of this preferred technical solution are as follows: By setting a dual determination mechanism of cancellation conditions and duration after triggering an early warning, the frequent triggering and cancellation of early warnings caused by short-term fluctuations in the tilt angle value near the threshold are avoided. This mechanism requires that the monitored parameters continuously meet the cancellation conditions for a preset duration before the early warning is lifted, ensuring the stability of the early warning status. This design, while ensuring safety, reduces the interference and misjudgment caused to operators by early warning flashing due to short-term data fluctuations, improving the system's practicality and operators' trust in the early warning signals.

[0013] As a preferred embodiment of the method for linking a pole tilting warning and buffer device according to the present invention, the step of sending alarm information to the receiving terminal via wireless communication includes: packaging the warning level, the composite tilt angle, and the tilt direction information into alarm data; sending the alarm data to the receiving terminal via a wireless module; waiting for a confirmation signal from the receiving terminal; and if the confirmation signal is not received within a preset waiting time, retransmitting the alarm data.

[0014] As a preferred embodiment of the method for linking a pole overturning warning and a buffer device according to the present invention, the buffer device's buffering response to the overturning movement includes: real-time detection of the current compression stroke of the elastic buffer structure; triggering a linkage signal when the current compression stroke reaches the preset limit value; and adjusting the warning level to the second warning level after receiving the linkage signal.

[0015] As a preferred embodiment of the method for linking a pole tilting warning and a buffer device according to the present invention, the step of calculating the current composite tilt angle based on the zero-point reference angle and the effective tilt angle value includes: calculating the deviation value between the effective tilt angle value and the corresponding zero-point reference angle of each monitoring axis; performing vector synthesis operation based on the deviation value of each monitoring axis to obtain the current composite tilt angle; and determining the tilt direction angle according to the deviation value of each monitoring axis.

[0016] This invention provides a system that links a power pole overturning warning system with a buffer device.

[0017] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a system for linking a utility pole overturning warning and a buffer device, comprising: a tilt angle monitoring module for real-time acquisition of tilt angle data of multiple monitoring axes of the utility pole; a signal processing module for filtering the tilt angle data to obtain effective tilt angle values, calculating the composite tilt angle and tilt change characteristic quantity, and recording state data during the warning event process; a graded warning module for determining the warning level based on the composite tilt angle and the tilt change characteristic quantity, and controlling the alarm device to output a corresponding alarm signal; a wireless communication module for sending alarm information to a receiving terminal when the warning level reaches the second warning level; a buffer device body, including an elastic buffer structure arranged along an arc trajectory for buffering response with the overturning movement of the utility pole, and triggering a linkage signal to adjust the warning level when the compression stroke of the elastic buffer structure reaches a preset limit value; and a power management module for supplying power to each module.

[0018] The present invention provides a computer device, including a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the steps of the method for linking a utility pole overturning warning and a buffer device.

[0019] The present invention provides a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, the steps of the method for linking a utility pole overturning warning and a buffer device are implemented.

[0020] The beneficial effects of this invention are: traditional visual observation and periodic inspection methods are replaced by continuous monitoring by tilt sensors, which can capture minute tilt changes and rapid overturning processes. Quantitative monitoring data provides an objective basis for safety judgments, avoiding the uncertainty of subjective judgments.

[0021] By setting two threshold levels, the risk of tilting is divided into three levels: alert, warning, and danger, with different alarm methods and handling measures corresponding to different levels. This tiered mechanism avoids frequent false alarms that affect operational efficiency while ensuring a mandatory response in the event of a real danger. The intermittent alarm of the first-level warning alerts workers to pay attention to the abnormality without causing panic, while the continuous alarm and mandatory evacuation order of the second-level warning ensure personnel safety.

[0022] Not only does it provide on-site alarms via audible and visual signals, but it also transmits early warning information to ground monitoring personnel in real time via wireless communication, achieving dual protection. Even if workers on the pole are focused on their tasks and ignore the on-site alarms, ground monitoring personnel can still promptly detect the anomaly via handheld terminals and direct evacuation via walkie-talkies. The introduction of wireless communication breaks through the limitations of traditional on-site alarms, constructing a multi-layered, multi-channel safety protection system.

[0023] Integrating the tilt monitoring and early warning system with the mechanical buffer device into a single unit saves installation space and achieves coordinated operation between early warning and buffering. The early warning system provides information and warnings in the early stages of overturning, buying time for evacuation; when the overturning continues after the warning, the buffer device activates, slowing down the overturning speed through energy absorption and providing final protection for personnel evacuation.

[0030] To make the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] Example 1, referring to Figure 1, is an embodiment of the present invention. This embodiment provides a method for linking a utility pole overturning warning with a buffer device, including: Step 1: When the utility pole is in an upright state, acquire the zero-point reference angles of multiple monitoring axes; Step 2: Collect the tilt angle data of the multiple monitoring axes in real time, filter the collected tilt angle data to obtain effective tilt angle values, and calculate the current composite tilt angle based on the zero-point reference angles and the effective tilt angle values; Step 3: Acquire multiple composite tilt angles within a preset time window, and calculate the tilt change characteristic quantity based on the composite tilt angles corresponding to the beginning and end times of the time window; Step 4: Determine the warning level using a multi-level judgment strategy based on the composite tilt angles and the tilt change characteristic quantity. The multi-level judgment strategy includes a first warning level and a second warning level, wherein the triggering condition of the first warning level is... The triggering condition for the second warning level is that the composite tilt angle exceeds the first threshold and the tilt change characteristic exceeds the change threshold; Step 5: Control the alarm device to output a corresponding alarm signal according to the warning level; Step 6: When the warning level reaches the second warning level, send alarm information to the receiving terminal via wireless communication; Step 7: When the utility pole overturns, the buffer device buffers the overturning movement. The buffer device includes an elastic buffer structure arranged along an arc trajectory. The compression deformation of the elastic buffer structure absorbs the torque generated by the overturning, and when the compression stroke of the elastic buffer structure reaches a preset limit value, a linkage signal is triggered to adjust the warning level; Step 8: Record the tilt angle data, warning level, and buffer device status during the warning event when the warning level is triggered.

[0032] This embodiment integrates a tilt sensor into the buffer device to collect real-time tilt angle data of the utility pole, transforming traditional qualitative judgment into precise quantitative monitoring. The system can detect minute tilt changes and capture abnormal signals in the early stages of overturning, providing accurate data support for subsequent early warning and emergency response. Two levels of warning thresholds are designed based on the degree of danger of the tilt angle. The first-level warning is triggered when the tilt angle exceeds 3 degrees, alerting workers to the abnormality through intermittent buzzing and flashing yellow lights, but not requiring immediate evacuation, allowing time for safety confirmation and adjustment. The second-level warning is triggered when the tilt angle exceeds 5 degrees, issuing a mandatory evacuation command through rapid, continuous buzzing and a constant red light. In addition to on-site alarms via sound and light signals, the warning information is also transmitted in real-time to the handheld terminals of ground monitoring personnel via a wireless communication module, achieving coordinated on-site and remote response. Ground personnel can visually view the current tilt angle, tilt direction, and trend of change of the utility pole through the terminal interface, enabling timely emergency decisions.

[0033] Furthermore, the system integrates tilt monitoring, tiered early warning, and buffer protection into a comprehensive protection system for power pole overturning. The system continuously monitors the pole's tilt using dual-axis tilt sensors mounted on the buffer device. A microprocessor collects sensor data in real time and filters it to eliminate vibration interference. The current tilt angle is then compared to a preset threshold. When the tilt angle exceeds the first-level warning threshold, the control circuit activates a buzzer to emit intermittent alarm sounds and a flashing yellow LED. When it exceeds the second-level warning threshold, a rapid, continuous alarm sound and a constantly lit red LED are activated, simultaneously triggering a wireless module to send an alarm message containing tilt angle data to the ground terminal. If the pole continues to tilt after the warning, the arc-shaped slide rail and buffer spring assembly of the mechanical buffer device activate, gradually absorbing energy to slow the overturning speed and buy more time for personnel evacuation.

[0034] Example 2, an embodiment of the present invention, provides a method for linking a pole overturning warning and a buffer device based on the previous embodiment, including: Step 2: Real-time acquisition of tilt angle data of the multiple monitoring axes, filtering of the acquired tilt angle data to obtain an effective tilt angle value, and calculation of the current composite tilt angle based on the zero-point reference angle and the effective tilt angle value, including the following steps A1-A6: A1: Maintaining a data buffer of a preset length, the data buffer being used to store multiple continuously acquired tilt angle data; A2: Adding newly acquired tilt angle data to the data buffer and removing the earliest tilt angle data from the data buffer; A3: Calculating the average value of all tilt angle data in the data buffer as the effective tilt angle value.

[0035] A4: Calculate the deviation between the effective tilt angle value and the corresponding zero-point reference angle for each monitoring axis; A5: Perform vector synthesis calculation based on the deviation values ​​for each monitoring axis to obtain the current synthesized tilt angle; A6: Determine the tilt direction angle based on the deviation values ​​for each monitoring axis.

[0036] Step 3: Obtaining multiple composite tilt angles within a preset time window, and calculating the tilt change characteristic quantity based on the composite tilt angles corresponding to the beginning and end times of the time window, includes the following steps B1-B3: B1: Grouping the multiple composite tilt angles within the time window according to time sequence to obtain several composite tilt angles of the starting time period and several composite tilt angles of the ending time period; B2: Performing statistical processing on the several composite tilt angles of the starting time period and several composite tilt angles of the ending time period respectively to obtain the starting tilt angle characteristic value and the ending tilt angle characteristic value; B3: Calculating the tilt change characteristic quantity based on the change relationship between the starting tilt angle characteristic value and the ending tilt angle characteristic value.

[0037] In this embodiment of the application, in step B2, the statistical processing is as follows: Step B2.11: Add up several composite dip angles in the initial time period and divide by the number of data to calculate the initial average dip angle as the initial dip angle characteristic value; Step B2.12: Add up several composite dip angles in the final time period and divide by the number of data to calculate the final average dip angle as the final dip angle characteristic value.

[0038] The time window length was set to 5 seconds, the sampling frequency was 10 Hz, and a total of 50 composite tilt angle data were collected within the time window. The first 5 data were taken at the beginning of the time period, and the last 5 data were taken at the end of the time period.

[0039] In an optional implementation, in step B2, the statistical processing can be performed as follows: Step B2.21: Assign increasing weights to several composite dip angles within the initial time period in chronological order, with data closer to the end of the time period having higher weights, and calculate the initial weighted average dip angle as the initial dip angle feature value, wherein the weight coefficients are set in a linearly increasing manner; Step B2.22: Assign increasing weights to several composite dip angles within the final time period in chronological order, with data closer to the end of the time period having higher weights, and calculate the final weighted average dip angle as the final dip angle feature value, so that the latest data within the time period has a more prominent influence on the feature value.

[0040] In another optional implementation, in step B2, the statistical processing can also be performed as follows: Step B2.31: Sort several composite dip angles within the initial time period according to their numerical values. When the number of data is odd, extract the value at the middle position as the initial dip angle feature value. When the number of data is even, extract the average of the two middle values ​​as the initial dip angle feature value. Step B2.32: Sort several composite dip angles within the final time period according to their numerical values. When the number of data is odd, extract the value at the middle position as the final dip angle feature value. When the number of data is even, extract the average of the two middle values ​​as the final dip angle feature value.

[0041] In this embodiment of the application, in step 3, the tilt change characteristic quantity is calculated by: step B3.11: calculating the difference between the end tilt angle characteristic value and the initial tilt angle characteristic value; step B3.12: dividing the difference by the duration of the time window to obtain the average tilt angle change rate as the tilt change characteristic quantity.

[0042] The time window is 5 seconds long. The rate of change of tilt angle per unit time is obtained by dividing the difference by 5 seconds. The unit is degrees per second. This rate of change reflects the speed at which the utility pole tilts.

[0043] In an optional implementation, in step 3, the tilt change characteristic quantity can be calculated by: step B3.21: obtaining multiple composite tilt angles arranged sequentially within the time window, calculating the difference between two adjacent composite tilt angles to obtain multiple first-order difference values; step B3.22: calculating the difference again between adjacent first-order difference values ​​to obtain second-order difference values; step B3.23: averaging the second-order difference values ​​to obtain the tilt angle change acceleration as the tilt change characteristic quantity, which reflects the trend of tilt velocity change.

[0044] In another optional implementation, in step 3, the tilt change characteristic quantity can also be calculated by: step B3.31: calculating the difference between the ending tilt angle characteristic value and the initial tilt angle characteristic value; step B3.32: calculating the ratio of the difference to the initial tilt angle characteristic value to obtain the tilt angle change rate as the tilt change characteristic quantity; step B3.33: when the initial tilt angle characteristic value is close to zero, the difference is directly used as the tilt change characteristic quantity.

[0045] Among them, the ratio form can reflect the relative change in the degree of tilt and is suitable for judging the tilt trend under different initial tilt angles.

[0046] In step 4: the multi-level judgment strategy is used to determine the warning level based on the composite tilt angle and the tilt change characteristic, including the following steps C1-C3: C1: After the warning is triggered, the composite tilt angle and the tilt change characteristic are continuously monitored; C2: It is determined whether the warning cancellation requirements are met according to the preset warning cancellation conditions; C3: When the warning cancellation conditions are met and the duration reaches the preset holding time, the current warning level is cancelled.

[0047] In this embodiment of the application, in step C2, the cancellation requirement is achieved through: Step C2.11: Determining whether the current composite tilt angle is lower than the threshold of the corresponding warning level, wherein the threshold corresponding to the first warning level is 3 degrees and the threshold corresponding to the second warning level is 5 degrees; Step C2.12: Determining whether the current tilt change characteristic quantity is lower than a preset stable threshold, wherein the preset stable threshold is set to 0.2 degrees per second; Step C2.13: When the judgment results of steps C2.11 and C2.12 are both yes, it is determined that the warning cancellation condition is met. The dual-condition judgment mechanism ensures that the pole not only tilts back to a safe range, but also that the tilt speed has stabilized.

[0048] In an optional implementation, in step C2, the cancellation requirement can be achieved through: Step C2.21: determining whether the current composite tilt angle is lower than the threshold of the corresponding warning level minus a preset hysteresis value, wherein the preset hysteresis value is set to 10% to 20% of the warning threshold; Step C2.22: when the determination result is yes, determining that the warning cancellation condition is met. By setting the hysteresis value to form a hysteresis comparison mechanism, frequent warning triggering and cancellation are avoided when the tilt angle fluctuates slightly around the threshold.

[0049] In another optional implementation, in step C2, the release requirement can also be achieved through: step C2.31: determining whether the current composite tilt angle is lower than the threshold of the corresponding warning level; step C2.32: calculating the standard deviation of the composite tilt angle within a preset monitoring period; step C2.33: determining whether the standard deviation is lower than a preset fluctuation threshold; step C2.34: when the judgment results of steps C2.31 and C2.33 are both yes, it is determined that the warning release condition is met. The standard deviation reflects the degree of fluctuation of the tilt angle data.

[0050] Step 6: When the warning level reaches the second warning level, an alarm message is sent to the receiving terminal via wireless communication, including the following steps D1-D4: D1: Pack the warning level, the composite tilt angle, and the tilt direction information into alarm data; D2: Send the alarm data to the receiving terminal via a wireless module; D3: Wait for the confirmation signal from the receiving terminal; D4: If the confirmation signal is not received within a preset waiting time, resend the alarm data.

[0051] In step 7: When the utility pole overturns, the buffer device responds with the overturning motion by buffering the movement, including the following steps E1-E3: E1: Real-time detection of the current compression stroke of the elastic buffer structure; E2: When the current compression stroke reaches the preset limit value, a linkage signal is triggered; E3: After receiving the linkage signal, the warning level is adjusted to the second warning level.

[0052] In this embodiment, in step 7, the elastic buffer structure is achieved through: Step 7.11: using a spring group arranged along an arc-shaped guide rail as the elastic buffer structure, the spring group comprising four sets of buffer springs arranged in parallel; Step 7.12: when the utility pole overturns, the slider slides along the arc-shaped guide rail and compresses the spring group; Step 7.13: the stiffness coefficient of the spring group is set to 8000 Newtons per meter, the buffer stroke is set to 0.15 meters, and the stroke limit switch is triggered when the compression reaches 0.12 meters. The arc-shaped guide rail matches the trajectory of the overturning utility pole, and the spring group absorbs the torque generated by the overturning through elastic potential energy. A single spring absorbs approximately 90 joules of energy at its maximum stroke, and the four sets of springs absorb a total of approximately 360 joules of energy.

[0053] In an optional implementation, in step 7, the elastic buffer structure can be achieved through: Step 7.21: using a hydraulic buffer as the elastic buffer structure, the hydraulic buffer including a hydraulic cylinder, a piston, and a damping adjustment mechanism; Step 7.22: when the utility pole overturns, the piston moves within the hydraulic cylinder, and hydraulic oil flows through the damping orifice to generate a damping force; Step 7.23: controlling the magnitude of the damping force by adjusting the size of the damping orifice, thereby achieving buffering control of the overturning speed. The hydraulic buffer can provide adjustable damping force, adapting to different utility pole masses and overturning speeds.

[0054] In another optional implementation, in step 7, the elastic buffer structure can further include: Step 7.31: using a rubber buffer pad as the elastic buffer structure, the rubber buffer pad being arranged along an arc-shaped trajectory on the contact surface of the buffer device; Step 7.32: when the utility pole overturns, the overturning moment acts on the rubber buffer pad, causing it to compress and deform; Step 7.33: the rubber buffer pad absorbs the overturning energy through its own elastic modulus and deformation, while providing a damping effect to slow down the overturning speed. The rubber buffer pad has the characteristics of simple structure and maintenance-free operation, making it suitable for applications where buffering accuracy requirements are not high.

[0055] Example 3, referring to Figures 1-5, is an embodiment of the present invention. Based on the previous embodiment, it provides a method for linking a utility pole tilting warning and buffer device, including: In step 1, after the system is powered on, the microprocessor first performs zero-point calibration on the tilt sensor. When the utility pole is in a normal upright state, the operator presses the calibration button. At this time, the system records the initial readings of the sensor in the X and Y axes as the zero-point reference. During the calibration process, the system averages 50 continuously collected data sets to improve the accuracy of the reference value.

[0056] Furthermore, the zero-point reference value is calculated as follows: the X-axis is taken as the north-south tilt monitoring axis, and the Y-axis is taken as the east-west tilt monitoring axis; the initial angles are recorded respectively. and These two reference values ​​are stored in non-volatile memory and will be retained even after a power outage and restart. After calibration, the system enters normal monitoring mode, and a solid green LED indicates that the system is working properly.

[0057] It should be noted that, to verify the sensor's operational status, the system also performs a self-test during the initialization phase. The microprocessor sends test commands to the sensor to check whether the sensor response is normal and whether the measurement data is within a reasonable range. If the self-test detects a sensor malfunction or communication abnormality, the LED indicator flashes yellow, and the buzzer emits a short beep, reminding the operator to check the equipment. Only after the self-test passes will the system enter normal operating mode.

[0058] In step 2, under normal operating conditions, the tilt sensor continuously acquires the tilt angle of the utility pole at a frequency of 10 Hz. The sensor, based on MEMS technology, uses silicon microstructures to sense the components of gravitational acceleration along different axes, thereby calculating the tilt angle. The sensor outputs a digital signal, which is transmitted to the microprocessor via an I2C bus.

[0059] Furthermore, due to interference factors such as wind vibration and construction vibration at the work site, the raw acquired data contains high-frequency noise. The system uses a sliding window mean filtering method to eliminate these interferences. Specifically, the microprocessor maintains a data buffer of length 10. Each time new data is acquired, the oldest data is removed from the buffer, the new data is added to the buffer, and then the average value of all data in the buffer is calculated as the current effective tilt angle value.

[0060] It should be noted that the filtered X-axis tilt angle is denoted as... The Y-axis tilt angle is denoted as The subscript t indicates the current sampling time. These two angle values ​​reflect the tilt of the utility pole in the north-south and east-west directions. To obtain the overall tilt angle of the utility pole, the system calculates the composite value of the two axial tilt angles.

[0061] Composite tilt angle The calculation formula is: (1) In the formula, The current composite tilt angle, in degrees; This represents the current X-axis tilt angle; This is the zero-point reference angle for the X-axis; This represents the current Y-axis tilt angle; This is the zero-point reference angle for the Y-axis.

[0062] This formula, based on the principle of spatial vector synthesis, can comprehensively reflect the degree of tilt of the utility pole in any direction. Simultaneously, the system also records the primary direction of tilt, facilitating subsequent assessment of the overturning trend. Tilting direction angle. The calculation formula is: (2) In the formula, The tilt angle is expressed in degrees, with true north as the reference and clockwise as the positive direction.

[0063] Calculated composite tilt angle The data is then sent to the next warning and judgment module. Simultaneously, the system stores the tilt angle data from the most recent 10 seconds in a circular buffer for analyzing tilt change trends.

[0064] In step 3, the tilt angle data may fluctuate due to measurement errors or instantaneous interference. To improve the accuracy of the early warning, the system analyzes the trend of tilt angle changes. The microprocessor calculates the average rate of change of tilt angle over the past 5 seconds.

[0065] Furthermore, the rate of change of tilt angle The calculation method is as follows: Take 50 sets of data collected within the last 5 seconds (sampling frequency 10 Hz), calculate the difference in tilt angle between the first and last sets of data, divide by the time interval, and the average rate of change can be obtained. To reduce the influence of random fluctuations, the average value of the first and last 5 sets of data is used for comparison in actual calculations.

[0066] The specific calculation formula is as follows: (3) In the formula, This is the average rate of change of the tilt angle, expressed in degrees per second. 5 represents the synthesized tilt angle value of the i-th sample; 5 represents the time window length in seconds.

[0067] Furthermore, the rate of change of tilt angle reflects the speed at which the pole tilts. If the rate of change is consistently positive and large, it indicates that the pole is tilting at an accelerating rate, posing a high level of danger; if the rate of change is close to zero or negative, it indicates that the tilt is stabilizing or recovering, posing a relatively low level of danger. The system combines the rate of change information with the current tilt angle value to make a comprehensive early warning judgment.

[0068] It should be noted that, to avoid false alarms caused by frequent triggering and cancellation of warnings within a short period, the system has a warning hold time. Once a warning is triggered, even if the tilt angle briefly drops below the threshold, the warning status remains for at least 3 seconds. The warning is only cancelled when the tilt angle remains below the threshold for 3 consecutive seconds and the rate of change is less than 0.2 degrees per second. This mechanism avoids warning flickering caused by data fluctuations through time lag.

[0069] In step 4, the system sets two levels of warning thresholds, corresponding to different hazard levels and response measures. The first-level warning threshold is set at 3 degrees, and the second-level warning threshold is set at 5 degrees. These two thresholds were determined based on a comprehensive analysis of the utility pole's mechanical properties and on-site operational experience.

[0070] When the tilt angle of the utility pole is less than 3 degrees, it is within the normal allowable range, and the system will not alarm. When the combined tilt angle is less than 3 degrees... A Level 1 alert is triggered when the temperature exceeds 3 degrees Celsius but does not reach 5 degrees Celsius. The criteria for triggering a Level 1 alert are as follows: and Simultaneously satisfying the rate of change condition: In the formula, 3 degrees is the first-level warning tilt angle threshold; 5 degrees is the second-level warning tilt angle threshold; and 0.1 degrees per second is the lower limit of the rate of change, used to exclude the case of static tilt.

[0071] Furthermore, a Level 1 warning indicates that the utility pole has begun to tilt noticeably, but has not yet reached a dangerous level. Workers should be vigilant, check the pole's condition, and adjust their work methods or reinforce guy wires if necessary. At this time, a buzzer sounds an intermittent warning tone, beating for 0.2 seconds and pausing for 0.8 seconds, while an LED light flashes yellow at a frequency of 1 Hz. This intermittent alarm effectively draws attention without causing excessive anxiety.

[0072] When the combined tilt angle A temperature exceeding 5 degrees Celsius triggers a Level II alert. The criteria for triggering a Level II alert are as follows: Regardless of the rate of change limit, it will be triggered immediately as long as the tilt angle exceeds 5 degrees.

[0073] A Level 2 warning indicates that the pole's tilt has reached a dangerous level and there is a risk of it overturning. Workers must immediately stop work and evacuate to a safe location. At this time, a buzzer sounds a continuous, urgent alarm, the LED light remains constantly red, and the wireless module sends an emergency alarm signal to the ground terminal. Once triggered, a Level 2 warning can only be deactivated after the tilt angle has decreased to below 3 degrees and remained stable for 5 seconds.

[0074] The early warning judgment logic is executed by the microprocessor once per sampling cycle, that is, once every 100 milliseconds. The delay time from the tilt angle exceeding the threshold to the output of the early warning signal does not exceed 100 milliseconds, ensuring timely response.

[0075] In step 5, based on the warning level, the system controls the buzzer and LED lights to output corresponding audible and visual signals. Both the buzzer and LED lights are mounted on the fixed plate of the buffer device, positioned 1.5 meters above the pole, facilitating observation by personnel on the pole and monitoring by personnel on the ground.

[0076] It should be noted that the buzzer is a piezoelectric buzzer with an operating voltage of 3.3 volts and a sound pressure level of 85 decibels (measured at a distance of 1 meter), ensuring it can be clearly heard in noisy working environments. The microprocessor controls the buzzer's on / off state and frequency via a PWM signal. For a first-level alarm, the PWM signal is output at a frequency of 1 Hz with a duty cycle of 20%, producing intermittent alarm sounds; for a second-level alarm, the PWM signal is continuously output, producing continuous alarm sounds.

[0077] Furthermore, the LED warning light uses tri-color LED beads, capable of displaying green, yellow, and red states. During normal operation, it displays a solid green light, indicating normal system operation and no tilting abnormalities; a first-level warning displays a flashing yellow light at a frequency of 1 Hz; and a second-level warning displays a solid red light. The LED light's driving circuit employs a constant current source design to ensure stable brightness even with battery voltage fluctuations.

[0078] It should be noted that the priority design of the audible and visual alarms ensures that when multiple warning levels are met simultaneously, the system outputs the signal according to the highest warning level. For example, when the tilt angle rapidly increases from 3 degrees to 5 degrees, the system directly outputs a red light and continuous alarm sound for the second-level warning, instead of first outputting a first-level warning and then switching to the second-level warning. This design avoids confusion and delay in warning signals.

[0079] In step 6, when a level-two warning is triggered, the system not only issues an audible and visual alarm on-site, but also transmits the alarm information to the handheld terminal of the ground monitoring personnel via the wireless communication module. The wireless communication uses LoRa technology in the 433 MHz band, which features long transmission distance, strong penetration capability, and low power consumption. In open environments, the communication distance can reach 500 meters, meeting the needs of on-site operations.

[0080] Furthermore, the microprocessor packages the data to be sent into data frames. The data frame format includes: device identification code (2 bytes), warning level (1 byte), current tilt angle value (2 bytes, accuracy 0.1 degrees), tilt direction angle (2 bytes, accuracy 1 degree), timestamp (4 bytes), and checksum (1 byte), totaling 12 bytes. The data frame is sent to the LoRa module via serial port, and the LoRa module modulates the digital signal into radio waves for transmission.

[0081] Furthermore, to ensure the reliable transmission of important alarm information, the system employs an acknowledgment and retransmission mechanism. After sending an alarm message, the system waits for an acknowledgment response from the ground terminal. If no acknowledgment is received within one second, the message is retransmitted, up to a maximum of three times. If no acknowledgment is received after three retransmissions, the system records a transmission failure log and indicates a communication failure by rapidly flashing an LED.

[0082] It should be noted that upon receiving an alarm message, the handheld terminal of the ground monitoring personnel immediately displays the tilt angle data, tilt direction, and warning level on the screen, while simultaneously vibrating and emitting an audible alert. The monitoring personnel can send voice commands to the walkie-talkies of the personnel working on the pole via the terminal interface to direct evacuation. The terminal can also record historical alarm data for post-event analysis.

[0083] In step 7, if the pole continues to tilt after the warning, the mechanical buffer device comes into play. The buffer device includes an arc-shaped fixing plate, a sliding guide rail, and a buffer spring assembly. The arc-shaped fixing plate is fixed to the pole with clamps, and the sliding guide rail is arranged in an arc shape. When the pole tilts, the slider slides along the guide rail and compresses the spring.

[0084] Furthermore, the design of the curved guide rail is based on the mechanical analysis of pole overturning. When the pole tilt angle is... At that time, the torque acting on the buffer device is: (4) In the formula, M is the overturning moment, in Newton-meter; m is the mass of the upper part of the pole (including the pole body, conductor and workers), in kilogram; g is the gravitational acceleration, taken as 9.8 m / s²; h is the vertical distance from the installation point of the buffer device to the center of gravity of the pole, in meters; The tilt angle.

[0085] Furthermore, the stiffness coefficient k of the buffer spring is designed based on the overturning moment and the allowable buffer stroke. The buffer stroke is set to 0.15 meters, requiring the spring to balance the overturning moment when compressed to the end of its stroke. The relationship between the spring force and the compression is as follows: (5) In the formula, F is the spring restoring force, in Newtons; k is the spring stiffness coefficient, in Newtons per meter; and x is the spring compression, in meters.

[0086] It should be noted that the component of the spring's restoring force in the guide rail direction generates a counter-torque, which reaches a stable state when balanced with the overturning moment. The required spring stiffness is determined using the moment balance equation. For a typical 10-meter-high pole, with an upper mass of approximately 150 kg and the buffer device installed 2 meters above the ground, the vertical distance from the center of gravity to the installation point is approximately 3 meters. When the tilt angle reaches 10 degrees, the overturning moment is approximately 760 Nm. The buffer spring is required to balance this moment within a 0.15-meter stroke, thus requiring a stiffness of approximately 6000 Nm. In practical designs, a spring with a stiffness of 8000 Nm is selected to provide a certain safety margin.

[0087] The energy absorbed during the buffering process is the elastic potential energy of the spring. (6) In the formula, E is the buffer absorption energy, and the unit is joule.

[0088] Furthermore, when the buffer stroke reaches its maximum value of 0.15 meters, a single spring absorbs approximately 90 joules of energy. The buffer device is equipped with four sets of springs, absorbing a total of 360 joules of energy, which can effectively slow down the overturning speed and buy time for personnel to evacuate.

[0089] It should be noted that the buffer device is also equipped with a travel limit switch. When the spring compression reaches 0.12 meters (80% of the designed travel), the limit switch is triggered, sending a signal to the microprocessor. Upon receiving the limit signal, the microprocessor immediately forces a switch to the second-level warning state, even if the tilt angle has not reached the 5-degree threshold. This is because the activation of the buffer device itself indicates that the pole is subjected to a significant external force, posing a high degree of danger.

[0090] In step 8, when a warning event occurs, the system switches to recording mode, recording information including tilt angle, direction, rate of change, warning level, and buffer device status. Data recording begins 10 seconds before the warning is triggered (backtracking from the circular buffer) and continues for 30 seconds after the warning ends. This detailed data provides a complete process record for post-accident analysis of the cause of the capsizing.

[0091] By analyzing historical data, long-term tilting trends of utility poles can be identified, providing a basis for foundation maintenance and reinforcement. For example, if the data shows that the pole is tilting slowly and continuously in a certain direction, it may be due to foundation settlement, requiring foundation reinforcement; if the data shows that the tilt angle fluctuates drastically in a specific wind direction, it may be necessary to add guy wires or adjust the direction of the guy wires.

[0092] Furthermore, the data logging function also supports accident investigations. When a rollover accident occurs, by reading detailed data before and after the accident, the rollover process can be reconstructed, and the rollover speed, direction, and triggering factors can be analyzed, providing a scientific basis for improving safety measures. The recorded warning time and worker response time are also important parameters for evaluating the effectiveness of the warning system.

[0093] As shown in Figure 2, the buffer device includes an airbag section. Over time, the airbag pressure gradually decreases. A miniature air replenishment module is added inside the device to replenish the airbag without disassembling the device. Figure 5 shows the air replenishment device, which is located inside this housing. After the device is installed on the utility pole, the control system is activated, and the air replenishment device operates, inflating the airbag to a certain pressure (preset value). After a period of time, the airbag pressure decreases to a certain range, triggering the air replenishment device to replenish air once the pressure reaches a certain value. The air replenishment valve stops when the pressure reaches a certain level. The air replenishment device is designed to fit within the ring-shaped device that holds the utility pole, and a pressure sensor is attached to the outside of the airbag.

[0094] Example 4 is an embodiment of the present invention, which provides a method for linking a power pole overturning warning and a buffer device. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through experiments.

[0095] To verify the validity of this patent, a three-month field test was conducted on a 10 kV distribution line. The test involved 15 utility poles, with the system installed on each pole, covering different operational scenarios and environmental conditions. A total of 52 pole-mounted operations were performed during the test, including routine inspections, equipment maintenance, and new line erection.

[0096] Table 1: Early Warning Response Time Test at Different Inclination Angles

[0097] Test results show that the system's detection response time is within 100 milliseconds under various tilt angle conditions, meeting the design requirements. The trigger times for Level 1 and Level 2 warnings are stable, with delays from detecting tilt exceeding limits to outputting warning signals all within 15 milliseconds. The wireless signal transmission delay remains within 150 milliseconds, ensuring that ground monitoring personnel receive alarm information promptly.

[0098] Table 2: Statistics on Early Warning Accuracy

[0099] In 52 operations, the system triggered Level 1 warnings 18 times. Two of these were temporary tilting incidents caused by strong winds; workers continued operations after confirming safety, and these were considered conservative false alarms. Level 2 warnings were triggered 7 times, all due to genuine hazardous situations, including 4 instances of tilting caused by soft ground and 3 instances of tilting caused by excessive work loads. Workers evacuated promptly after receiving the warnings, preventing potential accidents. The system did not miss any warnings, achieving an overall warning accuracy rate of 96.2%.

[0100] Table 3: System performance under different work scenarios

[0101] Routine inspection operations, due to their relatively small load, resulted in an average peak tilt angle of only 2.1 degrees, leading to a low warning trigger rate. Equipment maintenance and new line erection, however, were more demanding and prolonged, resulting in higher peak tilt angles and more frequent warning triggers. Particularly during new line erection, conductor tension caused significant lateral forces, with an average peak tilt angle reaching 5.8 degrees. In 10 out of 10 operations, warnings were triggered, with 5 operations interrupted due to persistently high tilt angles, only resuming after reinforcement of the guy wires. No safety incidents occurred during the 3-month trial period, demonstrating the system's effective improvement in operational safety.
