Automatic detection and Analysis system of Contact network

Abstract Since modern times, the development of the railway is particularly rapid, the popularity of the railway network and the degree of railway technology reflects the level of development of a region and the level of science and technology。 Railway to promote the development of the world, and promote the world civilization。 Compared with other countries, China's railway development is relatively late, but with the rapid development of China's economy and the level of science and technology, the rapid development of China's railway, railway technology is also becoming more advanced。 The current railway network has been basically all of the implementation of electrical, so as to ensure the normal operation of the railway line, the electric railway contact network detection and analysis of the task becomes particularly important。 This paper is mainly about the sensors and the wireless transmission technology based on, the realization of the catenary need preliminary supervisory control and data acquisition, data analysis of catenary "s parameters by single chip computer, with internal storage data real-time fault detection and timely the fault alarm。 The system with electrical chemical measurement of railway vehicle as the carrier, can realize the automatic acquisition of catenary "s parameters, real-time display, remote transmission and storage, query and complete the alarm task, has important practical significance for protection of electrified railway safe and smooth operation of the。
