Embodiment Construction

[0024] figure 1 A schematic cross-sectional view of a slot waveguide 1 is shown, showing how it is used in the prior art in a communication system for communication between a vehicle 4 traveling along a predetermined movement trajectory and a stationary Communication takes place between the base stations 5 and / or among a plurality of such vehicles. The antenna 3 of the vehicle extends into the slot waveguide 1 through the slot 2 to transmit and receive electromagnetic waves propagating along the slot waveguide 1 . When the vehicle moves along its predetermined movement track, the antenna 3 moves in the longitudinal direction of the slot waveguide 1 together with the vehicle. In particular, the vehicle 4 can be guided along a given route by rails.

[0025] Such as figure 2 As shown, the antenna 6 of the stationary base station 5 likewise protrudes into the slot waveguide 1 . The antenna is connected via a coupler 7 and optional attenuation elements 8 and 9 to two transceiv...

Abstract

In a communications system for communication between a vehicle guided along a predetermined movement path and a stationary station using a slotted waveguide which extends parallel to the movement path of the vehicle and into which at least one antenna connected to a transmitting and receiving unit of the stationary station and at least one antenna of the vehicle project, wherein the antenna of the vehicle is moved in the longitudinal direction of the slotted waveguide with a movement of the vehicle, on the stationary station and on the vehicle, either at least two separate transmitting and receiving units are provided for each respective transmission channel and are provided with a respective antenna connection, or at least one transmitting and receiving unit is provided for at least two transmission channels and is provided with two respective antenna connections, and the antenna connections of the transmitting and receiving units are connected to at least one common antenna via at least one coupler, wherein the signals of all transmission channels are emitted and received via said common antenna.

Description

technical field [0001] The invention relates to a communication system according to the preamble of claim 1 . Background technique [0002] Such a communication system is known, for example, from DE 10 2013 002 227 B4. It realizes communication with high bandwidth and high anti-interference between a vehicle traveling along a predetermined motion trajectory and a fixed base station. Correspondingly, the antenna is arranged on the vehicle such that the antenna protrudes through the slot into the cavity of the slot waveguide and can receive and / or emit electromagnetic waves propagating along the waveguide while the vehicle is running. The corresponding antennas of the fixed base stations are arranged at one end of the slot waveguide. [0003] In this type of communication system, a high data rate is required, especially since it should be used to control the movement of one or more vehicles relative to a base station at a fixed location, and this control is in some cases cri...
