FIELD: transport.SUBSTANCE: system contains electronic control unit to control attachments, transmission, engine and machine steering mechanisms, facility for measuring parameters of its motion (actual and ideal speed, slippage, etc.), control instruments and display. Machine motion parameter measurement is performed using micromechanical gyroscopes and accelerometers. In the system, prediction of running forward machine board slippage amount is performed with subsequent optimisation of machine turning radius. Following is implemented in the system: automatic adjustment of machine motion speed depending on motion route irregularities identified during previous machine run, as well as attachment control from condition that irregularities of ground surface formed by its cutting edge does not result in necessity to decrease rollback speed. Machine control is optimised for works on slopes and sidehills, on loosened rocky materials, in confined areas, when electric cables and metal objects are present in processed ground. Various types of machine motion programmed control are implemented including control over curved routes and over previous machine trace. Automated control of brakes and machine engine fuel feed is implemented.EFFECT: higher productivity of excavatory-transport machine and improvement of operator working conditions.12 cl, 1 dwg |
