Multiplex circuit arrangement, particularly for the actuation of load stations in motor vehicles
First Claim
1. A multiplex circuit arrangement, particularly for the actuation of load stations in motor vehicles, with each station including a hardware processor for the rapid serial exchange of data and a driver circuit, the multiplex circuit arrangement comprising a bus system operating with an active voltage level and a passive voltage level and with the individual load stations being connected together by a network structure of line sections each including a data line and a load line, and wherein:
- each end of each said data line is provided with a respective bidirectional bus coupling network, including a bus coupling station network at a respective said end of a data line connected to a station and a distributor network at the other said end of a respective said data line;
each said coupling network comprises a first analog amplifier and a second analog amplifier which is oppositely connected with said first analog amplifier; and
at least a plurality of central ones of said bus coupling distributor networks are combined into a central bus distributor arrangement.

Abstract
In a multiplex circuit arrangement, particularly for actuating load stations in motor vehicles, with the circuit including a bus system, an arrangement secure against malfunctions is realized in that the end of each data line (LD) is provided with a bidirectional bus coupling network (station network SN and distributor network VN) including two oppositely connected analog amplifiers (OP1, OP2), with at least a plurality of central bus coupling networks (distributor networks VN) being combined into a star-shaped central bus distributor arrangement (ZVA).
