Abstract

The invention relates to a railway section communication system based on an overhead contact line and an application thereof. The railway section communication system comprises a transmitting end and a receiving end which are mutually connected through the overhead contact line, wherein both of the transmitting end and the receiving end comprise an induction antenna, a communication base station and a covering antenna which are orderly connected with each other; the transmitting end compresses and modulates an acquired original signal, and then transmits the original signal to the overhead contact line through the induction antenna; and the receiving end receives a signal, despreads and modulates the signal through the base station and then restores the signal into the original signal. Compared with the prior art, the railway section communication system based on the overhead contact line provided by the invention increases the anti-jamming capability of the system through spread spectrum modulation and other technologies, and combines a speech coding transfer function, so that the problem of long distance communication of the railway section can be solved.

Description

technical field [0001] The invention relates to a railway interval communication system, in particular to a catenary-based railway interval communication system and its application. Background technique [0002] In recent years, power line broadband network access has attracted more and more attention due to its complete infrastructure, wide distribution, and low cost, especially in remote rural areas or sparsely populated areas, where it has strong practical value. Catenary carrier communication utilizes the existing electrified railway catenary and relatively mature power line carrier technology. It can realize two-way data communication between trains and the ground, and between trains without increasing infrastructure investment. The spectrum resources are loose and affected by the outside world. relatively little interference. [0003] At present, inter-area wireless communication mainly relies on technologies such as GSM-R, high-power radio stations, and differential ...
