Railway signal in-use cable conductor application identification system based on signal source excitation

Abstract

The invention provides a railway signal in-use cable conductor application identification system based on signal source excitation. The system comprises signal excitation source generating equipment and signal identification terminal equipment, wherein the signal excitation source generating equipment is arranged at an indoor branching cabinet, multiple signal sending channels of the signal excitation source generating equipment are connected with multiple terminals related to to-be-identified conductors, the signal excitation source generating equipment is used for producing multiple signal excitation sources with specific carrier frequencies and signals are applied to various connected terminals through various signal sending channels, and specific carrier frequencies are in one-to-one correspondence to the conductor applications; the signal identification terminal equipment is arranged at an outdoor identification point, and multiple signal receiving channels thereof are added on multiple to-be-identified conductors, and the signal identification terminal equipment is used for identifying carrier frequency corresponding to each signal receiving channel and identifying the application of each conductor by combining a corresponding relation between the specific carrier frequencies and the applications of the conductor. Through the method provided by the invention, the application definition of the conductor at each outdoor position of the in-use railway signal cable can be quickly and precisely identified

Description

technical field [0001] The invention relates to the field of railway signals, in particular to a system for identifying the use of cable core wires in use for railway signals based on signal source excitation. Background technique [0002] At present, in the construction or operation and maintenance of railway signals in the industry, it is often encountered that it is necessary to identify the use of each core wire at the outdoor end of a multi-core signal cable in use. Generally, it is traditionally distinguished and identified by looking at the design drawings and the colors of the cable core wires. This method is extremely inconvenient and error-prone. Especially in the emergency repair of railway signals, once a mistake is made, it is very easy to cause the construction period to be lengthened, resulting in a delay or longer fault processing time, which affects the efficiency of train operation. Contents of the invention [0003] The purpose of the present invention ...
