Description
Technical Field
The invention belongs to the technical field of power transmission tower state monitoring in the power industry, and particularly relates to a power transmission tower state monitoring device.
Background
In recent years, with the improvement of quality of life, the degree of dependence on power supply in daily life has also increased significantly. In order to adapt to the current situation of the high-speed economic development of China and meet the power demand of people in life and production, the scale of a power grid is continuously enlarged, and the requirement on the safe operation of a power transmission line is higher and higher. Meanwhile, resources in China are not distributed uniformly, and the potential of hydroelectric generation in western regions is huge but the development degree is extremely low. In order to effectively utilize hydraulic resources in western regions and drive economic development of power generation regions, China implements a 'west-east power transmission' plan, and the large-scale power transmission project also needs safe operation of a power transmission line as a guarantee. And traditional manual work is patrolled the line and is wasted manpower and materials, and when the shaft tower takes place slight deformation, the staff is difficult to in time discover with the naked eye, and if obvious deformation has appeared, then the shaft tower is in very dangerous state.
Therefore, the online monitoring of the power transmission tower is very important. The sensors commonly used for on-line monitoring of the power transmission tower are an acceleration sensor and an inclination angle sensor, the inclination rate of the tower can be obtained by using the inclination angle sensor, and the forward gradient, the transverse gradient and the comprehensive gradient of the tower are calculated by using a tower inclination model, so that the safety condition of the tower is evaluated. FBG stress sensors have also been designed by fiber grating sensing technology, and strain is calculated by measuring the reflected wavelength change. However, the sensor is susceptible to temperature, and the measurement accuracy and the system measurement range are limited by the demodulation technology.
In addition to sensors, monitoring may be performed using a satellite navigation system or other positioning techniques. The GPS attitude measurement system receives information such as carrier phase measured by a GPS satellite and inputs the information into the attitude measurement module, the attitude information is reflected by a baseline attitude angle, and the monitoring of the iron tower can be completed by solving the angle change of the baseline. Somebody utilizes big dipper satellite positioning system to monitor, and three big dipper antenna is settled respectively on three corner point at power transmission tower top, utilizes gesture measurement principle and satellite relative positioning, calculates the contained angle that obtains three points and constitute, and then obtains the angle of inclination of two directions. And on the basis, an MEMS sensor is used for acquiring the displacement and deformation information of the tower, and a barometer is used for acquiring air pressure information to correct the displacement and deformation data of the tower. However, most devices adopting the mode are quite complex, heavy in size and high in manufacturing cost, and are difficult to widely adopt in practice.
In addition, a high-resolution Synthetic Aperture Radar (SAR) satellite is used for monitoring, after the SAR image is obtained by the SAR, speckle filtering is carried out on the input SAR image, a peak value detection algorithm is selected for carrying out iron tower target detection by utilizing the characteristic that the iron tower target brightness is far higher than a background clutter, and finally deformation data of the tower is obtained. However, under severe weather conditions, the difficulty of image analysis is increased, and large errors are likely to occur in such monitoring modes.
In general, the characteristics of the related art of the existing transmission tower state monitoring device are embodied in the following three aspects:
(1) from the appearance of the device, most of the existing devices have complex structures or large sizes, and bring great difficulty to installation, debugging and operation in actual engineering
(2) In the aspect of power consumption, most of the existing devices have high power consumption, and the devices are very difficult to disassemble and charge, so that the existing devices are difficult to ensure long-term and stable operation in actual engineering; in addition, higher power consumption is also a waste of energy, and the requirements of energy conservation and environmental protection are difficult to achieve.
(3) The cost of the device. Most of the existing measuring devices which are relatively accurate utilize a plurality of high-cost components, the devices are quite expensive, and if the devices are put into engineering practice on a large scale, the cost of monitoring the state of the power transmission tower can be greatly improved. Therefore, the high cost also becomes a significant reason that many devices are difficult to put into practical use at present.
Taking a state monitoring device of a power transmission line tower wire system researched by Zhang Changhua et al as an example, the device uses a plurality of temperature, optical fiber strain, optical fiber acceleration sensors and optical cables, the device is complex, parts are dispersed and are not easy to install, and the existence of the optical cables also increases difficulty for installation and disassembly; and the use of a plurality of sensors leads to an increase in power consumption and cost of the device.
