Implementation And Application Of Portable Catenary Inspection System For High-speed Railway

Rail transport industry after years of development, our country undertakes the important task of transportation, occupies an important position in the national economy. In China, railway transport has now entered the era of high-speed rail, the continuous development of electrified railway catenary guarantee the safe operation of the power system put forward higher requirements. Currently, usually catenary rail cars or laser measuring instrument to achieve the full parameters such as monitoring equipment to achieve the status of OCS These traditional methods of detection monitoring Catenary has certain limitations, the need for specialized skylight time, and high efficiency.According to the current actual situation catenary detection, the paper proposes a suitable high-speed railway catenary portable video inspection equipment. Catenary inspection device as a portable device that can be quickly installed in the locomotive cab, dynamic video tour OCS does not require specialized skylight operating time. Issues in the design of the system, the hardware part is divided into two parts:an internal inspection video capture terminal consists of two industrial cameras and related regulatory agencies, a panoramic camera to achieve the state patrol along the railway line, another local camera used for gateway key components in contact imaging; inspection system for two hosts to manipulate the camera to get a video camera inspections and data display, storage and management.System software development part of the selection Qt software platform, C++ programming language. System uses Qt software platform to complete the host of related software design and development, to achieve the control Catenary camera inspection process, inspection data acquisition, display, storage and analysis.Equipment used in the development of the system will improve the efficiency of many visits extent, improve the utilization of skylights time, but also has great significance for the protection catenary power supply equipment for safe operation.
