Design And Application On Mine Hoist Control System Human-machine Interface Based MPI

Mine hoist is a transport vehicle in coal mines, Which is the main contact mode betweenthe internal and upper mine, Can be used in the mine shaft, slope, and can promote materialssuch as coal and ore, And lift personnel, tools, materials, equipments, etc., And it is the throatof the whole mine system. It is a very important part in the process of mine production, For itis in relation to the mine production efficiency and the mine safety, And even it may affect thesafety of the workers up and down the well.The man-machine interface is used to exchange information between the control systemand user, which is an important part of the whole mine hoist system. Man-machine interfacecan transmit information, display functions and set operation and other functions, And it alsocan greatly improve the human-machine interaction speed, reduce the probability of operatingpersonnel judgment error. The traditional human-machine interface in mine hoist uses LEDdigital tube or ordinary liquid crystal screen (12864), Which has simple function andcomplicated programming. While the man-machine interface designed with special hoist LCDdisplay has the characteristics of friendly interface and fast response, But for the highrequirements for development and maintenance. As well as system compatibility difference.Design of a general lifting system human-machine interface. Based on the touch screenconfiguration software, With the advantages of beautiful interface, high developmentefficiency, easy maintenance, simple operation, and wide application prospect.Based on the actual operation situation of Xiangtan manganese mine hoist, and the updaterequirement of the electric control system of mine hoist. The component of mine hoistelectrical control system is summarized, the characters of the mine hoist unsymmetrical fivespeed S curve are analyzed,model is builded, simulation verification using MATLAB isexecuted, The speed adjustment of mine hoist is analyzed, The design method of adaptivefuzzy PID speed controller is adopted, the experiment results show that the design is correctand feasible.According to the demand of Xiangtan manganese mine hoist and the operation of theConvention and the relevant national standards, A design of man-machine interface based ontouch screen control system is puted forward, Which obtains information through thecommunication between two sets of Siemens PLC using MPI bus protocol and the controlsystem, And it can communicate with PC through Ethernet. The touch screen has beautifulinterface, Simple operation and convenient, Powerful functions, And the human-machine interface has functions like system setup, Parameter display and monitoring, Alarm query logprocessing, Simulation animation display, Also the automatic management system, Earlywarning and other innovations.The man-machine interface has been successfully used in Xiangtan manganese mine hoist.Practice resource shows that the man-machine interface has fast response speed, beautifulinterface, Simple operation, and rich functions.
