82 Mobile Electronics 6 Interfaces for Mobile Electronics U Pumps, motors and valves with proportional or switched electrohydraulic control can be controlled directly from the outputs of the mobile electronic units U Integrated electronic units in hydraulic components are preferably controlled via the CAN bus or analog voltages U Such input devices as joysticks and foot pedals deliver setpoints in the form of input signals which are processed by control units, amplifiers or integrated electronic units. Hydraulics Electronics Here too, major advantages are obtained by using the CAN bus instead of analog voltages, such as the reduced wiring effort and extended diagnostic capabilities U Other input signals for control units or amplifiers are delivered by a whole variety of sensors. Signal transmission with analog voltages or currents frequently yields the advantage of unlimited speed for real-time control functions, although the CAN bus can also be used occasionally Man – machine interface Mechatronics Control panels: display keypad Pumps Motors Valves Integrated electronics Integrated sensors Setpoint input devices: joystick foot pedal Amplifiers Control units ECU System interface CAN bus Sensors: speed pressure force position angle External electronics: diesel engine PLC Software Standard software and specific application programs Application software BODAS programming system Parameterization with the PC software BODEM Software development Commissioning/service U Control panels with display and push-buttons are separate digital computers communicating with the control units via CAN bus U In addition, the CAN bus permits communication between several control units responsible for different tasks in the overall system (drive control, working functions, diesel fuel injection, PLC functions and others) Technical data of the CAN bus ISO/DIN 11898 (high speed) CAN specification 2.0 B active Data rate 50 kbit/s – 1 Mbit/s SAE J1939 protocol Customized protocols
Accumulators Hydraulic accumulators are used above all to minimize the pump drive power, to equalize volumes, to smooth pressure peaks, to store energy and to dampen pulsation. Characteristics U Bladder-type accumulators from 1 to 50 L U Diaphragm accumulators from 0.075 to 2.80 L U Safety and shutoff block U Charging and testing devices U Mounting elements U Safety elements U Accumulator charging valve 83 7
