| Transmission line condition monitoring system has been widely used in the field of power grid, at present in system mainly uses sensor based measuring method and need in wire or the tower installation for measuring different parameters requires the use of different measuring principle of the sensor. In recent years, it is concluded that the condition monitoring system has the defects of high operation cost and high failure rate. In recent years, many scientific and technical literature and manufacturers developed monitoring system based on image recognition technology by on the tower mounted camera time-lapse image wire, real-time coordinate change in the position of the wire is obtained by the image recognition technology, through the geometric and physical algorithm traverse state parameters, but this based on image recognition technology of the line status monitoring system as the lead in complex background and dim misty light, wire image recognition rate is not high, thereby it is difficult to achieve the quantitative monitoring of practical effect.This technology is the technical basis of the existing literature of science and technology and application results, is based on the experience of line state monitoring system sensor and image recognition technology, in order to improve the image recognition rate and improve the reliability of wire to reduce the failure rate of the target, especially the invention has significant visual features of target recognition as its goal, the basic principle is to "target" hanging on the line, when installing the calibration between the camera and the target on the tower wire superscript in the image coordinates of the relative position, operation, image sequence on time-lapse camera tower target moving with wire around, through the real-time processing of scene image recognition sequence the image processing system, the target coordinates and obtain image coordinates calibration data comparison, draw the curve of dynamic displacement of the conductor, and then through a few Any physical algorithm traverse state parameters, in order to achieve the conductor sag of conductor galloping amplitude and frequency, conductor aeolian vibration frequency and amplitude of the line parameters real-time quantitative measurement and wire icing thickness, line channel security zone state parameters of qualitative monitoring.This paper mainly focuses on the design and implementation of embedded software for image recognition based on the target object, and the software design and implementation of the line state parameter measurement. This paper relates to the image recognition algorithm and line status parameter measurement algorithm, from the existing literature of science and technology and application of technological achievements, especially for the target object image, after repeated revisions and optimization of its own algorithm and software system.Technology, this article "based on standard target image recognition technology of transmission line state monitoring system" has obtained the national utility model patent "and" patent ", the trial manufacture technology products through the CNAS verification mechanism of the product type test, and are hanging network testing and practical stage. |
