| At present,the mine company had still using ordinary refueling machine to supply oil for the electric wheel truck . Because the viscosity of the oil is higher,so the burden of oil pump is heavy and the measuring device of the refueling mechine is easy to damage in winter, it seriously influences the maintenance efficiency of the electric wheel truck. Jiangxi copper company is a largest copper enterprises in Asia,the paper researchs and develops a Intelligent refueling system of the electric wheel truck based on PC bus to improve the refueling efficiency of the electric wheel truck of Dexing copper plant of Jiangxi copper company and management efficiency so that to meet the refueling of the electric wheel truck.This refueling system controls by computer of the PC bus and combines with the PCI-1713 card for collecting the outer data and the PCI-1724 card for controlling open and close of the valve and the system of the variable frequency speed-regulating for controlling the stability of the oil pressure in pipeline .Proceeding with hardware and software, realizes intelligent refueling of the electric wheel truck and oil's computer manager.First, this paper analyses the refueling situations of the original electric wheel truck and brings forth a brand-new intelligent refueling project; Then,the paper introduces in detail the work principle and the design of the components of the refueling system;Finally, the paper summarizes the whole electric wheel truck refueling system,and puts forward the follow-up improved problems and research propect.The development of the whole system,based on the design theory of machinery and automatical control theory . Eventually, the intelligent refueling control system has successfully been developed through the repeated test , debug, improvement and optimization in the laboratory and on the scene . |
