With the rapid development of the sensor , optical fiber communications , computer technology , how the latest technology application to Catenary parameters detection in order to improve the overall performance of the detection system and the accuracy of the test results , current catenary parameter detection system development and a new hot spot of research , but also to adapt to the context of the current railway speed , the development of a new generation of high-speed catenary inspection vehicle needs . This thesis is based on the characteristics of the high-speed catenary parameter detection , given the catenary the principles and methods of detection of the relevant parameters , and design a detection system composed of hardware and software program . In this scenario , the use of a new type of photoelectric , fiber optic sensors to detect ; CAN bus and optical fiber as the transmission of serial data bus protocol module and transmission media , both to improve the data transfer rate , and simplify the transfer between the high and low pressure module channel isolation design ; detection parameters in the low-pressure environment through the expansion of the a / D card directly collected by the host , and mining of high-performance industrial computer processing power ; acquisition speed pulse signal directly from the host , to enable them to take the initiative to control and coordinate the entire the timing of the work to improve the reliability of the system , to simplify the system design and shorten the development cycle . Also, using a variety of measures to improve the anti-jamming capability , allowing the system to be able to run reliably in a strong magnetic field environment of a strong electric field catenary . After the scene run proved solutions used in the 200km / h speed Catenary relevant parameter detection system is reliable , the accuracy of the test results meet the site requirements for higher speed detection system research and design reference.
