Method for communicating information between an on-board control unit and a public transport network

Abstract

The invention relates to a method for communicating at least one piece of information between a first control unit (CU1) on-board a first vehicle (V1) and a public transport network, characterised in that: the information is transmitted by the first control unit (CU1) in the form of an instruction (T2W, T2Q, T2T), said instruction being transferred to a first communication unit (I / O_1) on-board the first vehicle; the first communication unit (I / O_1) establishes a data link outside the vehicle with a second communication unit (I / O_2, I / O_3) connected to a module (EXE2, EXE3) for executing said instruction, the second communication unit and the execution module being either arranged on the ground or on-board a second vehicle (V2) comprising a second control unit (CU3); in the event of a transmission to the second communication unit (I / O_2) on the ground, the execution module (EXE2) on the ground is controlled under a slave mode governed, for said instruction, by a master mode of the first control unit (CU1); and in the event of a transmission to the second on-board communication unit (I / O_3), the execution module (EXE3) on-board the second vehicle is controlled under a slave mode governed in such a way as to let the instruction be executed under a master mode of the first control unit (CU1), thus placing, at least temporarily, a second control unit (CU2) on-board the second vehicle under a slave mode in order to execute said instruction.

Description

technical field [0001] The invention mainly relates to a method for transferring at least one piece of information between a first control unit on board a first vehicle and a public transport network as stated in the preamble of claim 1 . Background technique [0002] Currently, the communication between the on-board equipment of the first vehicle (public transport type: train or its carriages, subway, tram, trolley bus, bus, etc.) and the public transport physical network (ground or other vehicle on-board equipment) Methods have the important property of being able to generate prompt and safe commands in particular, such as CBTC (communication-based train control) technology, which is well suited for self-guiding / autoguiding vehicles (eg without a driver). For this purpose, the control unit is mostly located in the ground infrastructure in order to be able to send information in the form of commands to vehicles or other ground equipment, such as switches or ground signal li...

Problems solved by technology

Such sites are complex because of the multiple expensive engineering operations (road network installations for connecting cables, placement of radio points such as "junction points" distributed along roads and forming a ground network, etc.)
