Title:
CONTROL ARRANGEMENT FOR A HYDRAULIC OR PNEUMATIC SYSTEM
Document Type and Number:
WIPO Patent Application WO2001033087
Kind Code:
A3
Abstract:
The invention relates to a control arrangement for a hydraulic or pneumatic system. At least one electrohydraulic or electropneumatic control valve (1) is provided. The at least one state variable of the control valve can be controlled and is evaluated in a control unit (8). Corresponding adjustment signals can be generated in said unit. A higher ranking control unit (11) is connected to the control valve via corresponding coupling elements and by means of a first bus system (10). An electronic circuit (8) is arranged on the control valve (1) respectively. Said circuit serves for controlling the control valve (1) and acts as a control unit for the state variables. A first standardised interface (9) for coupling the first bus system (10) is provided on the control unit and a second standardised interface (12) is provided for coupling a second internal bus system (12) having sensors (3, 4, 5; 25, 26, 27, 28) for the state variables of the control valve (1).
