Registering new substation in hazard warning system radio system involves substation sending search message to all reachable substations, selecting intermediate station, sending registration request

摘要

The method involves the new substation (T0) sending a search message to all reachable substations (TX2,TX3;TY2-TY5) and selecting a first intermediate station (TY5) from one or more substations, sending a wish to register message to the intermediate station addressed to a central station (ZY1), the central station deciding to accept or deny the request when it is forwarded by the intermediate station and if accepted sending a response message via the intermediate station with a substation number and system identifier.
