DEVICE FOR MONITORING AND CONTROL OVER OPERATION PARAMETERS OF ROAD BUILDING TRUCKS WITH HYDRAULIC SYSTEMS Russian patent published in 1995 - IPC

FIELD: road building machines. SUBSTANCE: device has information- control panel 1, manual control unit 10, hydraulic equipment 9 of machine 8, sensors 7 to monitor operating parameters, unit 11 to produce sound signal. The panel is additionally provided with electronic programmable computerized unit 2, unit 4 to select operation mode, unit 3 to generate computer codes, parametric storage unit 5, unit 6 of data (signals) converters from aboard sensors. Information-control panel 1 is provided also with digital indicator 12 and light indicators 14, 15, unit 13 to control keyboard with light indicators. Outputs of keyboard 13 of information-control panel 1 are electrically coupled to the first input of parametric unit 5, and inputs programmable computerized unit 2, unit 4 to select operation mode, unit 3 to generate computer codes. The first output of unit 3 to generate computer codes, outputs of unit 4 to select operation mode and parametric storage unit 5, are connected to inputs of programmable computerized unit 2. The second output of unit 3 to generate computer codes is connected to the second input of parametric unit 5. Outputs of aboard sensors 7 are connected to inputs of unit 6 of data converters. Output of the unit is electrically coupled to input of programmable computerized unit 2. The outputs of the latter are coupled to hydraulic equipment 9 of machine 8 and connected to inputs of dynamic loudspeaker 11 to transmit sound signal, digital indicator 12, and light indicators 14, 15 at information-control panel 1, as well as light indicators of the keyboard 13. EFFECT: widened function possibilities to control and display operating parameters, provision of automatic selection and setting rational operating modes, as well as control over in-machine processes. 2 dwg, 2 tbl
