Research On Intelligent Mill Control System Based On Internet+

In the operation process of mineral processing enterprises,grinding operations are the key link that directly affects final production.At present,most domestic concentrators apply advanced automated instrumentation equipment into the production line,but there is unstable load phenomenon in the grinding stage of system.Under the restrictions of site conditions,the plan of enterprise information reform is still in its infancy,it’s necessary to design intelligent mill control system based on internet+ technology,make a discovery on the road of merging automation and information of mineral processing.Contrary to the characteristics of non-linearity,hysteresis and time-varying of mill load during operation,it’s necessary to take expert control algorithm to achieve stable control of the grinding process,and design automatic ball-adding equipment by machine vision based on special mill controller,to achieve automated operation of perception layer device in grinding system.The gateway Raspberry Pi with flexible extension interface is selected to connect to grinding site equipment by real-time programming,and the information system could analyze working data by collecting mill load and current.Information management system is set up by network interconnection technology on the basis of gateway equipment,the grinding site data is stored in the My SQL database by LAMP platform which has the fittest performance.The Apache server applications are designed to connect with Android client through a virtual link established by Socket,and transmit real-time work data to the application side.The data could be rendered in the mobile terminal by friendly monitoring interface,which provides a convenient way of regulation for the managers,they could be allowed to issue control instructions under the premise of ensuring construction safety.Aiming at the problem of unstable work caused by increasing of mill load during debugging,the system makes a load characteristic linearization,which achieves a desired effect.The control system platform has a fine extended performance and broad application prospects.
