Distributed Controlsystemdesign Of Circular Storagewith Stackerand Reclaimer

Circular Storage with Stacker and Reclaimer due to its very flexible mode ofoperation, there are material piling and taking work separated from each other,non-interference in each other’s characteristics, it will be in the process of bulkmaterial handling occupies very important position in the future. Round yard in thisessay, on the basis of current situation of the development of material piling andtaking machine, through mastering Circular Storage with Stacker and Reclaimerprocess requirement, put forward the Circular Storage with Stacker Reclaimer anddistributing control system design principle, designed and developed in accordancewith Circular Storage with Stacker and Reclaimer process control system.Based on the Circular Storage with Stacker and Reclaimer working process andtechnology, to carry out the Circular Storage with Stacker and Reclaimer electricaldesign, the design idea of distributed control system is established. Electrical designprocess including: the calculation of power load table, the schematic diagram of theelectrical design, Circular Storage with Stacker and Reclaimer is controlled with thechain protection, etc. According to the Circular Storage with Stacker and Reclaimerinput and output signals, in situ components quantity more big on characteristics suchas distributed control principle.In the Circular Storage with Stacker and Reclaimer control system hardwareselection and auxiliary system design aspect, this paper adopted by the control systemcontroller device using the AB company ControlLogix series PLC in the UnitedStates, its powerful computing function enough meet the Circular Storage withStacker and Reclaimer and distributing control system de sign requirements.Transmission device adopts ABB ACS800hoisting macro inverter, its unique hoistingmacro instruction and DTC control can satisfy the Circular Storage with Stacker andReclaimer motor torque requirements. The use of auxiliary system make thedistributed control system for the Circular Storage with Stacker and Reclaimer controlwill be improved.Circular Storage with Stacker and Reclaimer control system hardwareconfiguration and program design, main completed the three aspects of content: one is the control system hardware configuration, mainly includes: ControlNet networkconfiguration, DeviceNet network configuration and the configuration of theEtherNet network. Second, communication between PLC master-slave station and thecommunication between the drive and controller. Through ControlNet networkcommunication between the PLC master-slave station, transmission Device and thecontroller USES the Device of communication-net bus connection. The use of thesecommunication bus greatly improve the reliability of the system is running. Third, theprogram design and development. Programming software using AB companyRSLogix5000software package, the package can provide ladder diagram, functionstructure of the text, the functional block diagram and sequence diagram editor.According to the Circular Storage with Stacker and Reclaimer, using theControlLogix specific programming software design meet the round yard automationcontrol requirements of material piling and taking machine process, realize theautomatic, semi-automatic and manual control of large machine.Through on-site commissioning and specific algorithm to improve the collectingand distributing control system can be fully realized the Circular Storage with Stackerand Reclaimer process operation and automatic material piling and taking work, thispaper design the Circular Storage with Stacker and Reclaimer in JiangYin port wharffinish debugging, and successfully used. The Circular Storage with Stacker andReclaimer based on circular yard of distributed control system not only can be used inthe Circular Storage with Stacker and Reclaimer, also can be applied to the cardumper, dou turbine used for bulk materials handling equipment, such as systemdesign method of bulk material equipment control system provides reference for thefuture.
