The Design And Study Of Centralized Control System For Mine Central Water Pump House

Drainage system is one of the necessary primary production systems of mine,the function of it is to drain mine water to the ground timely,safely,trusty,economical and reasonable so as to secure workers'life under the mine and the manufacture.To the LongGu Mine's actual situation and the verbose operation,hard labour intensity,time-consuming water pump start-up,inefficient systems operation exists in the mine central water pump house, a centralized control system is designed .By the use of AB ControlLogix PLC and transducer,the system can collect all kinds of running parameter, by testing corresponding parameter,the system controls each actuator such as sluice valve and so on to carry out some related operations. At the same time,by using HMI reflects the system's work state and the parameters though the mode of pictures,datas,characters and exchanges datas between communication module and comprehensive monitoring mainframe, by using modern communication technology, and adopting ethernet network, machine set running state and parameter messages of the central water pump house are transferred to control room on the ground to achieve the syetem's remote operation. Finally,the system can achieve functions of unattended and power valley-value period instead of peak-value period.At present,the centralized control system of the mine central water pump house has been consummated basically and installed for running at the work field, practice indicates the system running reliably and advances the roboticized level of management of the mine central water pump house.Because of communication interface that obligated,the syetem can connect the mine nformationalized system directly, accordingly ,it secures water pumps'attempering rationally,and advances the system's running efficiency and economic benefit.
