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
In the time laying overhead transmission line, inevitably can there is scissors crossing with house, trees and power line etc. in engineering circuit. In the time of environment temperature rising or power line load increase, scissors crossing place there will be the phenomenons such as sag becomes greatly, 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, the method addressing 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 is that range unit is hung on power line, and video monitoring apparatus and communication module are fixed on shaft tower. This method has not only increased the short circuit of circuit and the hidden danger that opens circuit, and the high intensity electromagnetic field of power circuit also affects the work of supervising device itself, thereby affects monitoring accuracy.
Summary of the invention
The present invention solves existing transmission line of electricity scissors crossing wireless monitoring method and has potential safety hazard, monitors the problems such as inaccurate, and a kind of transmission line of electricity scissors crossing wireless monitoring method and device are provided.
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 the ground center that is projected as with scissors crossing, interval 120 degree arranges three energy collecting temperatures, moisture signals, carry scissors crossing place id information and have the video monitoring device of radio communication function; Under scissors crossing place, on ground, be provided with the size scale of regular triangular prism shape, each video monitoring device gathers the vision signal of scissors crossing distance and size scale from visual angle separately; 2) video monitoring device sends to Surveillance center by work as ground temperature, moisture signal, corresponding vision signal and the id information of self that gather by radio communication; 3) in Surveillance center, according to id information, from database, index out the each supplemental characteristic of scissors crossing, these data comprise: shaft tower data, wire data, topography and geomorphology data and meteorological 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 coefficient of elasticity and linear expansion coefficient etc.; Topography and geomorphology data comprise: circuit number, longitude, latitude and height above sea level etc.; Meteorological data comprises: several sections of highest temperatures over the years, the extreme lowest temperature over the years, temperature on average over the years and maximum wind velocities over the years etc., above data all before the monitoring device of erecting bed, input database after investigation; By three photograph images taking under OPENGL tool analysis different azimuth, the scissors crossing distance of analytical calculation power line; 4) legacy data in comprehensive on-the-spot temperature, humidity information, scissors crossing distance and database, cross over on-the-spot three-dimensional coordinate by image processing techniques analog crossover, calculate the sag of scissors crossing place under three dimensions, maximum stress and other data of overhead transmission line; 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 power line, monitoring device is subject to the interference of electromagnetic field very little, therefore can ensure the reliable and stable of observation process. Image is obtained by three different orientation, and coordinates distance-measuring, has eliminated the sighting distance error of single photo image processing process, has also made up common range unit and can not Measurement accuracy two have intersected the defect of electric wire distance.
Realize the video monitoring device of the method for the invention, comprise MCU process chip, the input of MCU process chip is connected with temperature, humidity sensor, camera, and the output of MCU process chip is connected with 3G module and radio-frequency module. When work, described MCU process chip receives regularly temperature, the moisture signal at the scissors crossing scene of collection of temperature, humidity sensor, receive the image information (comprising size scale) of scissors crossing place that camera is taken simultaneously, then by 3G module by image information, humiture information with and interior ID pass to Surveillance center. Radio-frequency module is 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.
