METHOD FOR CONTROL OF LORRIES IN OPEN PITS DURING SELECTIVE ORE EXTRACTION AND SYSTEM FOR AUTOMATIC CONTROL OF ORE DELIVERY BY MEANS OF EXCAVATOR-LORRY COMPLEX Russian patent published in 1997 - IPC

FIELD: automatic control. SUBSTANCE: method involves detection of coordinates of excavator scoop and detection of rate of useful content in scoop using interpolation of tests. Central check point has unit for input of serial number of tip lorry, route transmission unit, first indication unit, control unit, scoop coordinates receiver, unit which stores test results, receiver of number of scoops, unit for selection of tip lorry address, unit which sets rate of useful content in ore, information storage unit. Computing unit calculates useful content in ore loaded in body of lorry. Excavator has control unit, which has excavator condition unit, scoop coordinate detector, counter of number of scoops, unit which receives load capacity of lorry, indicator. Tip lorry has lorry serial number transmission unit, route receiver, indicator. Control is provided by control unit through communication channels. EFFECT: increased quality of ore when direct test of ore during excavation is impossible. 2 cl, 2 dwg
