Abstract

The invention discloses a system, device and method for mobile communication based on a rail transit electric power contact system. The system comprises vehicle-mounted communication machines, first couplers, ground communication machines, and a contact net conducting wire, wherein the vehicle-mounted communication machines are connected with the contact net conducting wire through the first couplers; the ground communication machines are connected with the contact net conducting wire through the second couplers; the contact net conducting wire is used for signal transmission. Through the adoption of the technical scheme, reliable transmission of digital signals can be achieved, and reliability and stability of the communication system are improved.

Description

technical field [0001] The invention relates to the technical field of railway wireless communication, in particular to a mobile communication system, device and method based on rail transit power catenary. Background technique [0002] At present, in the electrified railway section, two types of methods are generally used to realize dedicated mobile communication between trains and between trains and certain objects on the ground: one is to use wireless communication technology, such as frequency modulation (or other methods) wireless train dispatching, GSM -R, digital trunking system, etc.; the second is to use inductive communication, such as 400KHz inductive communication system. Since the former is a relatively well-known technology in the industry (some are transplanted from public communication technology), we will not introduce it in detail, but briefly introduce the latter as follows: [0003] The inductive train wireless dispatching telephone system provides a ded...
