The method comprises the following steps:1), three video monitoring devices are arranged on the ground at the cross spanning part of the electric transmission lines; 2), collected local temperature and moisture signals, corresponding video signals and ID information of the video monitoring devices are sent by the video monitoring devices to a monitoring center through wireless communication; 3), in the supervision center, according to the ID information, parameter data at the cross spanning part is indexed from the database; three photo images shot in different positions are analyzed through an OPENGL tool, and the cross spanning distance of the electric transmission lines is analyzed and calculated; 4), sag value at the cross spanning part in three-dimensional space, the maximum stress of an overhead line and other date are calculated; 5), the date is compared with the international standard, and the situation that whether the data meets the standard or not is judged.
Description
Technical field
The present invention relates to the monitoring of transmission line of electricity scissors crossing, be specially transmission line of electricity scissors crossing wireless monitoring method and device.
Background technology
When laying overhead transmission line, inevitably there is scissors crossing with house, trees and line of electric force etc. in engineering circuit.When environment temperature raises or line of electric force load increases, scissors crossing place there will be the phenomenons such as sag becomes large, wire elongation, if process not in time, will likely cause the great electric power accidents such as transmission line of electricity single-phase earthing or phase fault.At present, solving the method for this problem, is the touring prospecting of line attendant mostly, in-site measurement, rare wireless monitoring device.Even if there is a small amount of wireless monitor scheme, majority hangs on line of electric force by distance measuring equipment, video monitoring apparatus and communication module is fixed on shaft tower.This method not only increases short circuit and the open circuit hidden danger of circuit, and the high intensity electromagnetic field of power circuit also affects the work of supervising device itself, thus affects monitoring accuracy.
Summary of the invention
The present invention solves existing transmission line of electricity scissors crossing wireless monitoring method to be existed potential safety hazard, monitors the problems such as inaccurate, provides a kind of transmission line of electricity scissors crossing wireless monitoring method and device.
The present invention adopts following technical scheme to realize: transmission line of electricity scissors crossing wireless monitoring method, realize as follows: 1) on the ground of transmission line of electricity scissors crossing place, be in scissors crossing and be groundly projected as center, 120 degree, interval layout, three energy collecting temperatures, moisture signal, carry scissors crossing place id information and there is the video monitoring device of radio communication function; Ground is provided with the size scale of regular triangular prism shape immediately below scissors crossing place, each video monitoring device gathers the vision signal of crossed crossing distance and size scale from respective visual angle; 2) the local epidemic disaster signal gathered, corresponding vision signal and the id information of self are sent to Surveillance center by radio communication by video monitoring device; 3) in Surveillance center, according to id information, from database, index out each supplemental characteristic of scissors crossing, these data comprise: shaft tower data, wire data, topography and geomorphology data and weather data.Wherein, shaft tower data comprise: shaft tower type, shaft tower material and shaft tower numbering etc.; Wire data comprise: wire gauge, wire diameter, final elasticity coefficient and linear expansion coefficient etc.; Topography and geomorphology data comprise: circuit number, longitude, latitude and height above sea level etc.; Weather data comprises: several sections of highest temperatures, Annual lowest climate temperature over the years, temperature on average over the years and maximum wind velocities over the years etc. over the years, above data all before the monitoring device of erecting stage, input database after investigation; With three photograph images taken under OPENGL tool analysis different azimuth, the crossed crossing distance of analytical calculation line of electric force; 4) legacy data in comprehensive on-the-spot epidemic disaster information, crossed crossing distance and database, on-the-spot three-dimensional coordinate is crossed over, the sag of scissors crossing place, the maximum stress of overhead transmission line and other data under calculating three dimensions by image processing techniques analog crossover; 5) above each data and GB are contrasted, judge whether to meet standard.
The method of the invention safely, efficient, real-time is good.Because video monitoring device is installed on the ground away from line of electric force, monitoring device is very little by the interference of electromagnetic field, therefore can ensure the reliable and stable of observation process.Image is obtained by three different orientation, and coordinates distance-measuring, eliminates the sighting distance error of single photo image processing process, and also compensate for common distance measuring equipment can not intersect the defect of electric wire distance by Measurement accuracy two.
Realize the video monitoring device of the method for the invention, comprise MCU process chip, the input end of MCU process chip is connected with temperature and relative humidity, camera, and the output terminal of MCU process chip is connected with 3G module and radio-frequency module.During work, described MCU process chip receives the epidemic disaster signal at the scissors crossing scene of temperature and relative humidity taken at regular intervals, receive the image information (comprising size scale) of scissors crossing place of camera shooting simultaneously, then by 3G module, image information, humiture information and the ID in it are passed to Surveillance center.Radio-frequency module is used for the communication of each video monitoring device inside, and its effect is the shooting time of synchronous images.
This video monitoring device reasonable in design, uniqueness, working stability is reliable.
