Description

Technical Field

[0001] The present invention relates to a power transmission tower status monitoring device based on an electrochemical induction vibration sensor, belonging to the technical field of power transmission tower status monitoring devices. Background Art

[0002] As an important power transmission facility, the occurrence of faults in power transmission towers will cause serious losses to the power system and people's production and life. Natural disasters such as lightning, storms, snow, landslides, and floods can cause the foundation of power transmission towers to deform, leading to serious accidents such as tower inclination, tower collapse, and wire breakage. At the same time, various phenomena such as theft of power facilities, climbing of power transmission towers, and illegal operations by staff also occur from time to time.

[0003] Currently, the inspection of power transmission towers mainly adopts the methods of manual line inspection and helicopter line inspection. Manual line inspection is inexpensive, but the inspection cycle is long, the labor intensity is high, and many towers are difficult to inspect due to terrain limitations, resulting in inspection blind spots. Helicopter line inspection currently mainly adopts two methods: manned and unmanned. The biggest defect of the former is the safety problem. The aircraft is easily affected by the weather when traveling, and the cost is very high, so it is less used. The unmanned aerial vehicle inspection method is mostly in the initial stage of research, with complex systems, and there are certain problems in operation stability and monitoring range.

[0004] Some people have studied and want to use the Beidou satellite precise positioning technology to achieve the inclination monitoring and early warning of transmission line towers. However, during the actual operation process, due to the influence of various factors, it will inevitably generate operation errors. To meet the millimeter-level accuracy requirements of tower inclination monitoring, it is necessary to synchronously observe the signals of no less than four satellites.

[0005] Some people have proposed to use a resistance strain sensor to measure the stress change of the tower pole and transmit the monitoring information through a wireless communication method. However, the resistance strain sensor has a large non-linearity for large strains, the output signal is weak, and the sensitivity is relatively low. Summary of the Invention

Specific embodiments

[0028] The following further elaborates on the specific embodiments of the present invention with reference to the accompanying drawings:

[0029] Specific embodiment 1: Refer to Figures 1-3 This embodiment is described. The power pole state monitoring device based on the electrochemical induction vibration sensor in this embodiment includes an electrochemical induction vibration sensor 4 and a control device. The electrochemical induction vibration sensor 4 is installed above the power pole, and the two-way tilt angle and vibration condition of the power pole are monitored through the electrochemical induction vibration sensor 4, and the control device processes and analyzes the data.

[0030] The control device includes a wireless communication module 6, a single-chip microcomputer 7, and a radio frequency module 8. The single-chip microcomputer 7 processes and analyzes the data. The wireless communication module 6 transmits the data within the area to the monitoring center, and the radio frequency module 8 transmits the data of each node to the main unit of the pole monitoring.

[0031] The electrochemical induction vibration sensor 4 includes a molecular-electronic eddy current conversion cavity 9, an electromagnetic feedback compensation system 10, a temperature compensation system 11, a signal acquisition / processing circuit 12, a power supply 13, and a housing package 14. The molecular-electronic eddy current conversion cavity 9, the electromagnetic feedback compensation system 10, the temperature compensation system 11, the signal acquisition / processing circuit 12, and the power supply 13 are connected in sequence.

[0032] The molecular-electronic eddy current conversion cavity 9 includes an electrolyte sealing cavity 15, an electrolyte 16, a plurality of electrodes 18, an insulation layer 17, and a wire 19. An insulation layer 17 is provided between two electrodes 18, and a plurality of electrodes 18 and the insulation layer 17 are integrally packaged in the same chip.

[0033] When the wire tower pole tilts, rotates or has other conditions, the attitude of the molecular-electron eddy current conversion cavity 9 in the electrochemical induction vibration sensor 4 changes, and the electrolyte 16 flows accordingly, changing the concentration of charged ions between the electrodes 18, and then generating a changing current in the external circuit. And this current changes with the change of the flow of the electrolyte 16, converting the current signal into a voltage signal that can be collected by the single-chip microcomputer 7. By observing the change of the voltage signal, the monitoring of the power tower pole is realized.

[0034] When the device detects that the tilt angle or vibration state of the tower pole exceeds the preset threshold, through the wireless communication module 6, the warning information of the tower pole tilt data is sent to the monitoring center to remind the management personnel to pay attention to the operation status of the tower pole and take corresponding maintenance measures.

[0035] The power tower pole status monitoring device based on the electrochemical induction vibration sensor further includes a wind speed sensor 1, and a wind speed sensor 1 is also installed above the power tower pole. There is also a solar power supply system 2 that supplies power to the entire monitoring device, and a temperature and humidity sensor 3 and a wind direction sensor 5 are also installed. The detection signals of the wind speed sensor 1, the temperature and humidity sensor 3 and the wind direction sensor 5 are fed back to the control system.

[0036] The electrochemical induction vibration sensor 4 is composed of a molecular-electron eddy current conversion cavity (M.E.T. cavity) 9, an electromagnetic feedback compensation system 10, a temperature compensation system 11, a signal acquisition / processing circuit 12, a power supply 13 and a housing package 14, etc. Among them, the M.E.T. cavity 9 includes an electrolyte sealing cavity 15, an electrolyte 16, electrodes 18, an insulating layer 17 and a wire 19. The electrodes 18 and the insulating layer 17 are usually integrally packaged in the same chip and are called the "electrochemical mechanism inertia sensitive element" (Sensing Element, abbreviated as "sensitive element"). The electrolyte sealing cavity 15 contains the electrolyte 16, the electrolyte 16 wraps the chip integrating the electrodes 18 and the insulating layer 17, and several wires are arranged on the side wall of the electrolyte sealing cavity 15.

[0037] The present invention mainly monitors the bidirectional tilt angle and vibration condition of the pole tower / iron tower through the electrochemical induction vibration sensor 4. When the wire pole tower is tilted, rotated, etc., the attitude of the M.E.T. cavity in the electrochemical induction vibration sensor 4 will change, and the electrolyte 16 will flow accordingly (the change amount of the electrolyte flow is very small in actual situations), changing the concentration of charged ions between the electrodes, and then generating a changing current in the external circuit. And this current changes with the change of the electrolyte flow. The current signal is converted into a voltage signal that can be collected by the single-chip microcomputer 7. By observing the change of the voltage signal, the monitoring of the power pole tower is realized. Combining meteorological data (temperature, humidity, wind speed, rainfall), after analyzing the monitored data, relevant parameters are displayed in the form of digital lists, curves and charts; a trend analysis graph is made through trend analysis software to accurately infer the tilt condition and development trend of the pole tower.

[0038] When the device monitors that the tilt angle or vibration state of the pole tower exceeds the preset threshold, the system can send the alarm information of the pole tower tilt data to the monitoring center through the 3G / 4G wireless network, reminding the management personnel to pay attention to the operation condition of the pole tower and take corresponding maintenance measures.

The prior art has not applied the electrochemical induction vibration sensor to monitor the bidirectional tilt angle and vibration condition of the power pole tower, which is a breakthrough of the present invention.

[0040] The specific embodiments described above further elaborate on the purpose, technical solution and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. It can also be a reasonable combination of the features described in the above various embodiments.
