Wind Detection Of Catenary Systems Design And Implementation

Nanjiang Line and Xinlan Line often be driven to stop the rail transportation along the line by strong sandstorm weather, it will restrict the development of the rail transportation. Therefore, which build the wall of wind resist along the railway line, in addition, the construction of the wind wall has protected the train, however, which change the airflow field, it will effect Catenary systems shift dramatically and issue safety problem of rail transportation.To measure wind offset of catenary system under big storm environment which has important significance for improving railway operational safety, improving the railway transport capacity. At present, there is no method on the wind offset measurement both at domestic and abroad. This article proposed the use of digital image technology-based measurement system to measure wind offset. it design measurement system base on this method, furthermore, which use this method would be highly accuracy to detect the retortion, displacement and elevation data in the key parts of catenary system that measure the curve of wind offset of catenary system and the measurement of Precision to meet the project requirements; In addition, it can be measured without contact with the target to obtain wind offset results, which can test stable for a long time that do not interfere with traffic. Test results including numerical data and image data; which can in progress real-time display and history inquiry for the test result, so the test results display in time-curve or data image.This method designs testing identification which has fixed shape, it obviously different from background that convenient to deal with software testing system in real time. Before the time of testing that should binding the testing identification and testing object. In addition, we catch image information of Catenary system by CCD that ensures system could synchronized testing several test point inscribed on space distribution. The computer processing image of catenary system from video camera, according to image position and length of testing identification that processing retortion, displacement and elevation data, finally data will send to the communication server. Due to massive of recorded data, communication server will be packed the data and then send to buffer area that writing to the database after a while. Client-side should finish data inquiry and curve drawing. In this article, part of codes of processing program are implementing on the OpenCV base.Now, the testing system has applied in railway trail section of China.
