Collector wire network for the communication of locally fixed systems having at least one variable-location system part

The invention relates to a collector wire network (100) for the communication of locally fixed system parts (101) having at least one variable-location system part. According to the invention, data transmission devices (51, 52, 53, 54) each are assigned a reception range (E1, E2, E3, E4), wherein the reception range (E1, E2, E3, E4) is mapped onto a section which results from a length (11, 12, 13, 14) of a collector wire segment (10, 20, 30, 40) plus a first overlap length (111) and a second overlap length (112), wherein the data transmission device (51, 52, 53, 54) connected to the respective collector wire segment (10, 20, 30, 40) is configured in such a way that a level of the data signal transmitted thereby is matched to the respective reception range (E1, E2, E3, E4) in such a way that, because of attenuation of the level, caused by line damping along the conductor (1, 2) and the coupling elements (11, 12, 13, 14), the level in a receiving device (56) of the variable-location system part (102) which is located outside the reception range (E1, E2, E3, E4) can no longer be evaluated as a valid signal.
