Device for bidirectional transmission of data words

摘要

In known devices of this kind, data words are transmitted bidirectionally between a control unit and a number of interfaces, each of which is assigned to a sensor or actuator which supplies information to the interface or receives information from it, via a line system in the form of bus lines, via which the data words are transmitted in the form of electrical signals. In the device (1) according to the invention, the line system (2) has at least one transmission section (8) for contactless, bidirectional transmission of data words. At each end of the transmission section (8), a transmitting unit (13) and a receiving unit (14) are arranged. In this way, part of the interface (4) can be arranged on a system (10) which is mobile relative to the control unit (3). With the transmission section (8), transmission of data words can continue even with a mobile system (10) which is moving relative to the control unit (3). <IMAGE>
