Abstract
Description
Technical Field
[0001] The invention discloses a power pole tower adjacent construction and external force intrusion monitoring device and a monitoring method thereof, belonging to the field of electrical equipment and electrical engineering in the field of electronic information engineering, and is a vibration monitoring device and a monitoring method. Background Art
[0002] Since power towers are erected in areas with very different natural environments, they are often damaged by external forces. The main causes of external force damage include:
[0003] (1) Vehicles, plants, machinery and other foreign objects directly touch or impact the tower;
[0004] (2) Acts such as cutting tower materials, climbing illegally, and removing bolts with the purpose of stealing power facilities.
[0005] The current measures to deal with external force damage mainly adopt video surveillance. However, due to insufficient clarity or obstructed vision, video surveillance generally cannot observe the details of the tower. In addition, due to power and data bandwidth limitations, video surveillance cannot monitor in real time, so there is a disadvantage of untimely response to some external force damage. For example, when a vehicle collides with a tower or steals tower materials at night, or a vehicle collides with a tower or soil is piled near the tower in the blind spot of video surveillance during the day, the conventional disposal method is to wait for the daytime video surveillance personnel to discover or the line patrol personnel to discover and feedback, which has the problem of untimely feedback or omission. Construction near the tower has the characteristics of short periodicity and strong suddenness. Considering the economy and the reusability of the device, a monitoring device and method that is easy to load and unload, portable, and can monitor and feedback the damage in a timely manner is needed. Summary of the invention
[0006] The purpose of the present invention is to provide a monitoring device and method for the construction and external force intrusion of power towers in view of the above-mentioned shortcomings, which can sense vibration signals, combine intelligent analysis, and detect the external force intrusion of towers in real time by monitoring the vibration of towers in real time. Even when excavators, bulldozers, heavy vehicles and other machinery and vehicles are approaching but have not yet touched the towers, the vibration transmitted from the ground to the towers can achieve the purpose of early detection of external force intrusion. This is a monitoring method for the construction and external force intrusion of power towers that is simple to implement, easy to implement, and has accurate diagnosis.
[0007] The present invention is achieved by adopting the following technical solutions:
[0008] A method for monitoring power tower proximity construction and external force intrusion, comprising the following steps:
[0009] (1) Install a vibration sensor at a vertical distance of m meters from the ground and at the position of the pole tower body, and continuously and real-time collect vibration signals, where m is a rational number. When it is negative, it means the sensor is arranged on the pole tower below the ground; the noise of the vibration sensor itself, the maximum value of the absolute value of its time-domain data is Smax, which is a positive rational number;
[0010] (2) Within a predetermined sampling time period, collect the pole tower vibration acceleration signal at a preset sampling time interval T1 to obtain a vibration data sequence V1(i);
[0011] where i = 1, 2, 3,..., G1, G1 is an integer, representing the number of collected vibration data; take the maximum value in V1(i) as V1max, and V1max is a positive rational number;
[0012] (3) Compare the maximum value V1max in the vibration signal with the sensor noise;
[0013] When V1max < B × Smax, it means there is no abnormal vibration signal at this time, and then return to step (2) for resampling;
[0014] When V1max ≥ B × Smax, it means there is an abnormal vibration signal, and then enter step (4);
[0015] where B is a positive rational number greater than 1;
[0016] (4) Perform Fourier transform on the vibration data sequence V1(i) to obtain frequency and amplitude pairs (p1(j), f1(j));
[0017] where: p1(j) is the frequency, j = 1, 2, 3,..., D1, D1 is a positive integer;
[0018] f1(j) is the amplitude, which is the amplitude corresponding to the sine component with p1(j) as the frequency, j = 1, 2, 3,..., D1; V1(i) contains j sine components with p1(j) as the frequency and f1(j) as the amplitude in the frequency domain; make a spectrogram of the frequency and amplitude pairs (p1(j), f1(j));
[0019] (5) When constructing within a range of c meters from the adjacent power pole or iron tower, or when there is an external force invading the power pole or iron tower, there will be vibration signal components from a Hz to b Hz in the vibration signal, where a and b are both positive rational numbers and a < b; at the same time, in order to avoid the influence of the sensor itself noise, so take out D2 peak values that satisfy the conditions a < p1(j) < b and f1(j) ≥ B × Smax in the spectrogram; where, k = 1, 2, 3,..., D2, D2 is a positive integer;
[0020] Calculate the energy sum H in the following way:
[0021]
[0022] (6) If H ≥ Y, it is determined that there is a power pole near construction or external force intrusion; otherwise, it is determined that there is no power pole near construction or external force intrusion; where Y is the threshold value, which is a positive rational number.
[0023] In step (1), the value of m is 2.5.
[0024] The vibration signal in step (1) is an acceleration signal.
[0025] When the vibration sensor is a JF-2020 piezoelectric sensor, the Smax value in step (1) is 0.0002 m / s 2 The vibration sensor can be adsorbed on the iron tower by a magnet, or the vibration sensor can be tightly fixed on the iron tower or other tower bodies by adding components, bolts, etc. The components can be made of materials such as clamps and iron sheets.
[0026] In step (3), the value of B is 5000.
[0027] In step (5), the value of c is 2; in step (5), the values of a and b are 80 and 1000 respectively.
[0028] In step (6), the threshold Y=20.
[0029] We found that the vibration and dancing of the wires on the tower will be transmitted to the tower, and the tower will also vibrate under wind load excitation. The frequency of wire vibration, dancing and tower vibration under wind load is within 20Hz, which is outside the frequency range of 80-1000Hz investigated by the present invention, and therefore does not affect the present method. The characteristic frequency of 80-1000Hz for tower construction and external force intrusion is obtained by experiment.
[0030] The device for monitoring the construction near a power tower and external force intrusion comprises a vibration sensor and a control box; the vibration sensor is provided with at least one and relatively fixedly mounted on the power tower; the control box is also relatively fixedly mounted on the power tower, a control circuit board and a power module are arranged in the control box, a signal acquisition module, an A / D digital-to-analog converter, a central processing unit, a storage module, a human-computer interaction module, a signal sending module and an acoustic-optical alarm module are mounted on the control circuit board; a human-computer interaction interface is arranged on the control box, and the human-computer interaction interface is internally connected to the human-computer interaction module through a data line; the signal acquisition module is connected to the A / D digital-to-analog converter; the central processing unit is respectively connected to the A / D analog-to-digital converter, the storage module, the human-computer interaction module, the signal sending module and the acoustic-optical alarm module; the human-computer interaction module communicates with the central processing unit in a two-way manner; the power module provides working power for the components on the control circuit board.
[0031] The central processing unit adopts C8051F340 chip.
[0032] The device communicates with the outside world through a human-computer interaction interface, which meets the USB serial port data bus standard and can be used as both an input interface and an output interface. Supported input devices (i.e., human-computer interaction devices) include buttons, touch screens, and can perform operations such as device reset. By connecting a laptop computer to this interface, communication with the central processing unit can be achieved, data can be read, or programs can be written to the central processing unit.
[0033] The signal acquisition module uses a low-noise cable to connect to the vibration sensor, collect the tower vibration signal and ensure the stability of the cable position. The signal is then sent to the A / D converter for analog-to-digital conversion and transmitted to the central processor.
[0034] The storage module uses a data storage device to store monitoring data for easy reference later. The data storage device can use a Risym SD memory card module, which is directly driven by a central processing unit and communicates with the central processing unit in an SPI manner.
[0035] The signal sending module is used to send the alarm signal to the mobile monitoring terminal to promptly notify the relevant responsible personnel. The mobile monitoring terminal includes a mobile phone and other terminals supporting GSM or GPRS technology.
[0036] The sound and light alarm module is used to send warnings to the surrounding areas of the power poles and towers through LED flashes and sound information, so that people around can notice the existence of the power poles and towers.
[0037] The power module is powered by a 12V200AH lithium battery, has a size of 30cm×24cm×6cm, weighs 6kg, and can provide stable power for at least 1 year. The central processing unit can collect battery power signals. When the power is lower than 10%, the central processing unit notifies the responsible personnel to replace the battery through the signal sending module. The device based on the method of the present invention consumes less power, and the battery module can provide continuous power for at least one year, meeting the general monitoring cycle requirements for nearby construction. After the construction near the tower is completed or the hidden danger of external force intrusion is eliminated, the device based on the method of the present invention can be disassembled for the next use. The control box of the device has a size of 32cm×25cm×10cm and a weight of 9kg, which is easy to carry, install, and disassemble.
[0038] The monitoring device for construction near power poles and external force intrusion of the present invention has a simple structure, reasonable design, and is easy to install and use. The monitoring method for construction near power poles and external force intrusion of the present invention is expressed in C language and written into the central processing unit. The central processing unit collects and analyzes data according to the method of the present invention. When it is found that there is construction near the power pole or external force intrudes on the pole body, the surrounding personnel, machinery, and vehicles of the pole are reminded by the sound and light warning module not to accidentally touch the pole. At the same time, the signal sending module notifies the power supply workers to come and check through the short message platform.
[0039] The beneficial effects brought by the present invention adopting the above technical solutions are as follows:
[0040] 1) Effectiveness
[0041] Under wind load, the vibration and dancing of the conductor and the vibration frequency of the power pole are within 20Hz, outside the frequency band of 80 - 1000Hz investigated by the present invention, so it does not affect this method. The characteristic frequency of construction near the power pole and external force intrusion, 80 - 1000Hz, is obtained through experiments. And the abnormal vibration signal is much larger in amplitude than the noise signal自带 by the sensor, and the noise frequency band of the sensor is below 50Hz, which will not affect the 80 - 1000Hz characteristic signal.
[0042] 2) Low power consumption, easy to load and unload, and convenient to carry
[0043] Based on the fact that the present invention uses a vibration sensor and a microprocessor, it has low power consumption and can continuously monitor in real time. During monitoring, if the time-domain vibration signal V1max < B×Smax, only the sensor signal needs to be monitored without performing Fourier transform. Only when V1max ≥ B×Smax will Fourier transform and further data processing be carried out. This can reduce the working complexity of the microprocessor and reduce the power consumption of the device.
[0044] The device based on the method of the present invention has low power consumption, and the battery module can continuously supply power for one year, meeting the monitoring cycle requirements for general construction near the power pole. After the construction near the power pole ends or the hidden danger of external force intrusion is eliminated, the device based on the method of the present invention can be disassembled for the next use. The control box of the device has dimensions of 32cm × 25cm × 10cm and weighs 9kg, and is easy to carry, install, and disassemble.
[0045] 3) The contents that can be monitored by the present invention include mechanical construction such as excavators, bulldozers, and heavy vehicles near the power pole that can generate ground vibration and conduct it to the power pole, and vehicle passing phenomena; phenomena such as foreign objects such as vehicles, plants, and machinery directly touching and impacting the power pole; behaviors such as cutting tower members, climbing illegally, and disassembling bolts; and other phenomena that can generate vibration on the power pole or transfer vibration to the power pole through media such as the ground.

[0054] The following is combined with Figures 1 to 6 The present invention is described in detail with reference to the accompanying drawings and specific embodiments.
[0055] See attached Figures 1-2 , a monitoring device for construction near a power tower and external force intrusion, comprising a vibration sensor 2 and a control box 3; at least one vibration sensor 2 is provided, which is relatively fixedly installed on the power tower 1; the control box 3 is also relatively fixedly installed on the power tower 1, a control circuit board and a power module are arranged in the control box 3, a signal acquisition module, an A / D digital-to-analog converter, a central processing unit, a storage module, a human-computer interaction module, a signal sending module and an acoustic and optical alarm module are installed on the control circuit board; a human-computer interaction interface is provided on the control box, and the human-computer interaction interface is connected to the human-computer interaction module through a data line; the signal acquisition module is connected to the A / D digital-to-analog converter; the central processing unit is respectively connected to the A / D analog-to-digital converter, the storage module, the human-computer interaction module, the signal sending module and the acoustic and optical alarm module; the human-computer interaction module communicates with the central processing unit in a two-way manner; the power module provides working power for the components on the control circuit board.
[0056] The signal acquisition module uses a low-noise cable to connect to the vibration sensor 2 to collect the tower vibration signal and ensure the stability of the cable position. The signal is then sent to the A / D converter for analog-to-digital conversion and transmitted to the central processor.
[0057] In this embodiment, the signal sending module adopts the SIM800C module, which is used to send the alarm signal to the mobile monitoring terminal to notify the relevant responsible personnel in a timely manner. The mobile monitoring terminal includes mobile phones and other terminals supporting GSM or GPRS technologies.
[0058] The acoustic-optic alarm module adopts a commercially available small acoustic-optic alarm, which is used to send out warnings around the power pole tower through LED flashes and sound information, so that the surrounding people can notice the existence of the power pole tower.
[0059] The power supply module is powered by a 12V 200AH lithium battery, which can provide stable electric energy for a long time. The central processor can collect the battery power signal. When the power is lower than 10%, the central processor notifies the responsible personnel to replace the battery through the signal sending module.
[0060] In practical applications, power pole towers include concrete poles, steel pipe towers, steel pipe poles, angle steel towers, etc. Considering that an external force damage test needs to be carried out, in this embodiment, a retired 110kV steel pipe pole to be demolished is tested.
[0061] The parameters of the steel pipe pole are shown in Table 1.
[0062] Table 1 Parameters of the steel pipe pole
[0063] Voltage level / kV wire Steel pipe material Exhalation height / m Single base weight / kg 110 Double loop, single split Q420 steel 12 5104.04
[0064] The JF2020 type sensor is fixed on the steel pipe pole at a height of 2.5 meters from the ground by means of magnetic adsorption, which is used to monitor the vibration acceleration signal.
[0065] The steps of this embodiment are as follows:
[0066] 1) Collect the vibration acceleration signal of the pole tower at a preset sampling time interval of 0.0001 seconds within a preset sampling time period of 1 second. At this time, there is no abnormal vibration, and the obtained signal is the noise signal of the sensor itself. The maximum absolute value of its time-domain signal corresponds to Figure 3 the midpoint (0.0765, -0.0002278), indicating that at 0.0765 seconds, the absolute value of the time-domain signal is the largest, Smax = 0.0002278. To illustrate the present invention, the Fourier transform is performed on the time-domain signal to obtain the spectrum of the pole tower without abnormal vibration, as Figure 4 shown. It can be seen that when there is no abnormal vibration, the vibration signal is mainly the sensor noise and its main vibration component frequency is below 50Hz. In the actual application of the present invention, the Fourier transform will not be performed when V1max < B × Smax.
[0067] 2) Use a hammer to strike the steel pipe tower to simulate the phenomena of plants and machinery, vehicles touching, impacting the tower, as well as cutting the tower and disassembling bolts. Collect the vibration acceleration signal of the tower at a preset sampling time interval of 0.0001 seconds within a preset sampling time period of 1 second. Obtain the vibration data sequence V1(i), where i = 1, 2, 3, …, G1, and G1 = 10000, representing the number of vibration data collected.
[0068] 3) The maximum absolute value of the time-domain signal corresponding to the data collected in step 2) Figure 5 corresponds to the midpoint (0.5358, 6.68), indicating that at 0.5358 seconds, the absolute value of the time-domain signal is the largest, that is, V1max = 6.68. And B = 5000, by comparison, V1max > B × Smax, indicating that there is an abnormal vibration signal, and then enter step 4).
[0069] 4) Perform Fourier transform on V1(i) to obtain the frequency and amplitude pairs (p1(j), f1(j)), where: p1(j) is the frequency, j = 1, 2, 3, …, D1, and D1 is a positive number; f1(j) is the amplitude, which is the amplitude corresponding to the sine component with p1(j) as the frequency, j = 1, 2, 3, …, D1. V1(i) contains j sine components with p1(j) as the frequency and f1(j) as the amplitude in the frequency domain. Make a spectrogram of the frequency and amplitude pairs (p1(j), f1(j)), as Figure 6 shown.
[0070] 5) In the spectrogram (i.e., Figure 6 ) extract D2 peak values that satisfy the conditions a < p1(j) < b and f1(j) ≥ B × Smax. Among them, k = 1, 2, 3, …, D2, and D2 is a positive integer. For this signal, D2 = 4, see the 4 marked points in Figure 6 . Calculate the energy sum H in the following way:
[0071]
[0072] The energy sum H of this signal = 1.545 2 +1.707 2 +1.553 2 +6.36 2 = 48.16.
[0073] 6) And Y = 20. Obviously, H > Y, then it is determined that there is construction near the power tower or external force intrusion.
[0074] The content that the present invention can monitor includes:
[0075] 1) Mechanical construction phenomena such as excavators, bulldozers, and heavy vehicles near the tower that can generate ground vibrations and conduct them to the tower, and the phenomenon of heavy vehicles passing by;
[0076] 2) Vehicles, plants, machinery and other foreign objects directly touch or impact the tower;
[0077] 3) Cutting tower materials, illegal climbing, dismantling bolts, etc.;
[0078] 4) Other phenomena that can generate vibrations on the tower or transmit vibrations to the tower via the ground or other media.
[0079] The monitoring method of the present invention is not limited to the specific schemes of the above-mentioned embodiments, and all technical schemes formed by equivalent replacement are within the protection scope required by the present invention.
