Description

Technical Field

[0001] This invention relates to the field of power equipment monitoring technology, specifically to an intelligent monitoring device and method for pole tilt. Background Technology

[0002] As a key supporting structure in power transmission systems, the vertical stability of utility poles directly affects the safety and reliability of power transmission. During long-term use, utility poles are prone to tilting and deformation due to factors such as geological subsidence, natural disasters, external impacts, and environmental erosion. If these issues are not detected and addressed in a timely manner, they may lead to serious safety accidents such as short circuits and pole collapses, causing significant economic losses and personal injury.

[0003] Existing methods for monitoring pole tilt largely rely on manual inspections, which are labor-intensive, inefficient, and lack precision. Furthermore, they are limited by environmental conditions and human experience, making real-time continuous monitoring difficult and resulting in blind spots and delays. Traditional external detection devices are susceptible to environmental damage and experience rapid accuracy degradation. They also have limited data transmission and coverage capabilities, high power supply and maintenance costs, are ill-suited for complex terrains and extreme environments, have poor real-time and continuous monitoring performance, and are weak at detecting minute deformations or early risks. Some existing monitoring equipment has complex structures and low levels of intelligence, making it unable to accurately detect minute pole tilt displacements. Moreover, it lacks a stable power supply and timely early warning mechanisms, failing to meet the power system's requirements for real-time monitoring of pole safety status. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent monitoring device and method for pole tilt. The device has a simple structure, accurate monitoring, and stable battery life. It can realize real-time monitoring and early warning of pole tilt, reduce labor costs, and ensure the safety of power transmission.

[0005] The technical solution to achieve the objective of this invention is:

[0006] An intelligent pole tilt monitoring device is disclosed, which coordinates the functions of a laser tester, GNSS, reflector, solar panel, battery, and alarm via a microcomputer to construct an intelligent pole tilt monitoring system integrating real-time monitoring, data processing, and automatic early warning. Through a dual monitoring mode of laser ranging and satellite positioning, it accurately acquires pole tilt data. After analysis and processing by the microcomputer, it automatically alarms for abnormal conditions, ensuring that the pole's safety status is controllable in real time.

[0007] A test method for an intelligent monitoring device for pole tilt includes the following steps:

[0008] 1) Select the pole to be monitored, fix the reflector at the preset height position in the middle of the pole, and ensure that the surface of the reflector is flat and perpendicular to the pole axis; fix the laser tester and GNSS on a stable base near the pole, adjust the height of the laser tester to be flush with the reflector, so that the laser beam emitted by the laser tester is accurately projected onto the center of the reflector to form a reflection centerline.

[0009] 2) Fix the integrated electrical box in a safe position, and connect the laser tester, GNSS, solar panel and integrated electrical box with cables respectively, ensuring that the line connection is firm and the insulation is good; turn on the main switch, start the equipment for initial debugging, and set the pole tilt warning threshold through the microcomputer. According to the provisions of "DL / T741-2019 Overhead Transmission Line Operation Regulations" and the material of the pole to be monitored, the default warning threshold is set to tilt less than 1.5%.

[0010] 3) The solar panels begin collecting solar energy and converting it into electrical energy. Part of this electricity can directly power the laser testing instrument, GNSS, microcomputer, and alarm, while the other part can charge the battery. The microcomputer monitors the battery level in real time to ensure a stable power supply to the equipment.

[0011] 4) The laser tester continuously emits a laser beam, monitors the deviation of the reflected line through the light reflected by the reflector, and calculates the pole tilt in real time; GNSS synchronously collects the pole position coordinate data, and the monitoring data of both are transmitted to the microcomputer through a cable.

[0012] 5) The microcomputer performs real-time analysis and processing of the received tilt angle data and position coordinate data. When the tilt angle of the pole is not detected to exceed the warning threshold, the equipment continues to monitor and record data normally. When the tilt angle of the pole is detected to exceed the warning threshold, the microcomputer immediately triggers the alarm to start and issues an audible and visual alarm signal.

[0013] 6) After receiving the alarm signal, staff can retrieve historical monitoring data through the microcomputer, analyze the trend of pole tilting, and take timely corrective measures; if it is necessary to adjust the warning threshold, the parameters can be modified through the microcomputer.

[0014] 7) During the test, the real-time tilt of the pole monitored by the laser tester, the position coordinates of the pole monitored by GNSS, and the real-time battery power were continuously recorded. The monitoring was carried out continuously for 24 hours a day to verify the stability of the equipment operation and the accuracy of the monitoring data, and to ensure that problems were dealt with in a timely manner.

[0015] 8) After completing the monitoring test, compile the monitoring data and generate a pole tilt status monitoring report. The pole tilt status monitoring report should be graded to reflect the pole tilt status.

[0016] The present invention provides an intelligent monitoring device and method for pole tilt, which has the following advantages:

[0017] 1. By adopting laser monitoring mode and GNSS positioning, the accuracy and reliability of pole tilt monitoring are effectively improved. It can accurately capture minute tilt displacements and accurately locate the position of each monitored pole.

[0020] 4. The equipment has a simple structure and is easy to install. The integrated electrical box has good protective performance and is suitable for pole monitoring in different climate conditions and terrain environments, making it highly versatile.

[0021] 5. It can store historical monitoring data, support data export and trend analysis, provide a scientific basis for pole maintenance, and extend the service life of poles. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this is not intended to limit the scope of the invention.

[0026] Example:

[0027] As shown in Figures 1 and 2, an intelligent pole tilt monitoring device consists of a pole 1, a laser tester 2, a reflector 3, a GNSS 6, a solar panel 7, an integrated electrical box 8, and a cable 9. The integrated electrical box 8 contains a battery 10, a main switch 11, a microcomputer 12, and an alarm 13, thus providing an intelligent monitoring device for pole tilt. The microcomputer 12 coordinates and controls the operating parameters of the laser tester 2 and the GNSS 6, collecting real-time tilt data of the pole 1. The solar panel 7 provides continuous power to the device. When the tilt of the pole 1 exceeds a preset threshold, the alarm 13 automatically sounds an alarm.

[0028] The aforementioned intelligent pole tilt monitoring device is characterized in that the laser beam emitted by the laser tester 2 is reflected by the reflector 3 to form a reflection centerline 4. When the pole 1 tilts, the reflection line deviates to form an offset reflection line 5. The laser tester 2 calculates the tilt degree based on the offset amount, and the GNSS 6 collects position coordinate data. Both data are transmitted to the microcomputer 12 for processing.

[0029] A test method for an intelligent monitoring device for pole tilt includes the following steps:

[0030] 1) Select a concrete pole in a 10kV transmission line as the monitoring object. Fix the reflector 3 to the pole 1 at a height of 0.5m above the ground with bolts, ensuring that the reflector 3 is perpendicular to the axis of the pole 1. Install a laser tester 2 on the top of the center of the pole 1, and adjust the laser tester 2 so that the laser beam is accurately projected onto the center of the reflector 3, forming a reflection centerline 4.

[0031] 2) Install the GNSS 6 on the top of pole 1 and label each monitoring pole according to the coordinates provided by the GNSS 6 positioning. Fix the integrated power box 8 on a bracket 2.0 m above the ground at the bottom of pole 1. Connect the laser tester 2, GNSS 6, solar panel 7 and integrated power box 8 in sequence through cable 9. After checking that the wiring is correct, turn on the main switch 11 and set the tilt warning threshold to 1° through the microcomputer 12 to complete the equipment initialization.

[0032] 3) The solar panel 7 starts generating electricity under sunlight to power the laser tester 2, GNSS 6, microcomputer 12, and alarm 13, while charging the battery 10. The microcomputer 12 displays the real-time power level of the battery 10 to ensure normal power supply.

[0033] 4) The laser tester 2 emits a laser beam once per minute, and monitors the offset by the light reflected by the reflector 3 to calculate the tilt of the pole 1; GNSS 6 synchronously collects the position coordinates of the pole 1, and the two sets of data are transmitted to the microcomputer 12 in real time.

[0034] 5) The microcomputer 12 analyzes and processes the received data. According to the "DL / T741-2019 Operation Regulations for Overhead Transmission Lines", the inclination of reinforced concrete poles for AC lines shall not exceed 1.5% (i.e., 15 / 100), and should be kept within a reasonable range under normal operating conditions. For old poles, if the inclination exceeds 1.5% (i.e., 15 / 100), climbing the pole is strictly prohibited, and anti-falling measures must be taken first. When the inclination of pole 1 is 1.5%, the equipment continuously monitors and records the data; when the pole is artificially simulated to tilt to 1.5%, the microcomputer 12 immediately triggers the alarm 13 to issue an audible and visual alarm signal.

[0035] 6) After receiving the alarm signal, the staff will retrieve the real-time monitoring report of the pole tilt status through the microcomputer 12, and confirm the pole tilt trend according to the pole tilt level classified in the monitoring report. They will then arrange for personnel to conduct on-site verification and take reinforcement measures.

[0036] 7) The equipment operated normally during the 24 / 7 monitoring period, including sunny days, nighttime darkness, and short-term rainfall. Battery 10 provided continuous power at night, and the monitoring data was continuous and complete without any abnormal interruptions.

[0037] 8) After the test, turn off the main switch 11, export and organize the monitoring data to generate a pole tilt status monitoring report. The pole tilt status monitoring report reflects the pole tilt status in different levels. The microcomputer 12 generates a pole tilt status analysis report to verify that the equipment's monitoring accuracy, endurance, and alarm function all meet the design requirements.
