Car dumper hopper feeding control system and method

Abstract

The invention relates to the technical field of automatic control, and discloses a car dumper hopper feeding control system and a car dumper hopper feeding control method which solve the problem that the working capacity of an operation driver is too high. The car dumper hopper feeding control system comprises a high material level signal switch, a low material level signal switch and a controller; the controller comprises a feeding control unit, a discharge coefficient determination unit and a feeding quantity percentage determination unit; the feeding control unit is used for starting a plurality of hopper activation feeding machines at a predetermined time interval sequentially and controlling the feeding of the hopper activation feeding machines according to the predetermined feeding quantity percentage; the discharge coefficient determination unit is used for determining a discharge coefficient of each hopper activation feeding machine according to the starting sequence of the hopper activation feeding machines, readings of a belt weigher and the predetermined feeding quantity percentage; and the feeding quantity percentage determination unit is used for determining the actual feeding quantity percentage of each hopper activation feeding machine according to the readings of the belt weigher, a high material level signal, a low material level signal, a predetermined adjustment factor and the discharge coefficient. The car dumper hopper feeding control system and a car dumper hopper feeding control method are applicable to a feeding process of a car dumper.

Description

Technical field [0001] The invention relates to the technical field of automatic control, and in particular to a hopper feeding control system and method for a car dumper. Background technique [0002] The process of dumping the C80 model by the dumper of the third and fourth phases of Huanghua Port is that the dumper dumps the heavy trucks on the four-section dumper platform into nine evenly distributed hoppers, and then sends the coal to the Belt. The operator can control the feeding amount of each feeder within 0-1350T / h by adjusting the feeding percentage coefficient on the operation interface. [0003] During the operation, the operator must closely monitor the material level of each hopper through a surveillance camera or ask the unhooking personnel, and make appropriate changes to the feed coefficient of each hopper to ensure that appropriate feed is left in each hopper This leads to a linear increase in the workload of the operating driver. If the operator is negligent, ...
