Overhead wire icing on-line monitoring device based on machine vision

Abstract

The invention discloses an overhead wire icing on-line monitoring device based on machine vision, which is composed of hardware and software, wherein the hardware is divided into a lower computer and an upper computer; the lower computer hardware comprises a controlling and processing unit based on DSP, an image acquisition unit, a data acquisition unit, a data storage unit, a GPRS wireless communication unit and a solar energy photovoltaic light source unit; the upper computer hardware is composed of a monitoring center server unit and a GPRS wireless communication unit; and the upper computer hardware and the lower computer hardware realize wireless communication via a GPRS wireless network. The software is also divided into an upper computer and a lower computer, wherein, the lower computer software is in charge of driving the lower computer hardware to collect images and data, and the lower computer software calculates and judges icing thickness and type according to the collected image; then the GPRS wireless communication unit is driven to send compressed image and monitoring results to the upper computer; the upper computer software is in charge of driving upper computer hardware to finish GRPS wireless communication and realizes human-computer interaction interface and monitoring information management. The invention can monitor icing disasters on all sides.

Description

(1) Technical field: [0001] The invention provides an on-line icing monitoring device for overhead lines based on machine vision technology. The device can monitor the thickness and density of icing on overhead lines in real time, and judge the type of icing, so as to realize the monitoring and early warning of icing disasters on overhead lines. It involves machine vision, data acquisition, embedded image processing and wireless communication technology based on General Packet Radio Service (GPRS). GPRS wireless communication corresponds to GPRS wireless communication unit in the device hardware structure, and corresponds to GPRS wireless communication thread in the device software structure. . The device belongs to the category of image processing and monitoring devices. (two) background technology: [0002] With a vast territory and diverse terrain, my country is one of the countries with serious ice-covered disasters. At the beginning of 2008, severe icing disasters in...

Problems solved by technology

This method is simple and intuitive, but it only collects ice-covered images without further analysis of the images, and does not provide important parameters such as ice-covered thickness and density. The degree of ice-covered disasters also requires staff to make judgments through images, which lacks science. sex
