    • The invention relates to a bus system for transmitting data between data processing units (20) in a network, by means of a bus (14) that consists of two signal lines. The signals at said bus (14) are analog signals which lie within a plurality of non-overlapping frequency bands assigned to the individual data processing units (20), and these data processing units (20) use a digital communication protocol to communicate with a signal processor unit (24) that comprises a polyphase filter bank, a D/A Converter (26) and a bus-coupling unit (30) being connected downstream of said bank in order to couple the data signal into the bus (14) in a galvanically-isolated manner. The proposed bus system has a simple design with regard to cabling, allows the use of a Standard communication protocol such as Ethernet for the data processing units (20), and additionally allows data to be transmitted between all network subscribers simultaneously and without restriction.
    • 本发明涉及一种用于通过由两条信号线组成的总线(14)在网络中的数据处理单元(20)之间传输数据的总线系统。 所述总线(14)上的信号是分配给各个数据处理单元(20)的多个非重叠频带内的模拟信号,并且这些数据处理单元(20)使用数字通信协议来与 信号处理器单元(24),其包括多相滤波器组,D / A转换器(26)和总线耦合单元(30),其连接在所述存储体的下游,以便将数据信号耦合到总线(14)中 一种电流隔离的方式。 所提出的总线系统对于布线具有简单的设计,允许对数据处理单元(20)使用诸如以太网的标准通信协议,并且还允许在所有网络订户之间同时且没有限制地传输数据。
