Based On The PLC QBZ-200N Vacuum Magnetic Starter Design And Impiementation

In recent years, China's coal production has made brilliant achievements, coal mining equipment basically get rid of the silly and crude conditions, high yield and efficiency of mechanized equipment in coal production is more and more, switching equipment and a higher requirement, QBZ-200 N Vacuum Magnetic Starter is designed to meet this demand developed.Projects coal mine face drainage automatic control system for the carrier, the vacuum magnetic starter system power control master switch to achieve the load on-off control. This project has designed a true Control Magnetic Starter, PLC control procedures and the touch screen configuration control software, to achieve automatic control of down hole face drainage system to ensure that the underground face drainage is safe and reliable, advanced technology. This issue through a needs analysis of the project, discusses the man-machine interface of the PLC and touch screen control system advanced to determine the system modules: data acquisition module, function module of the PLC, the PLC module, touch screen control module,protection module, and automatic diagnostic module. System process: sensor data acquisition, PLC function module(A / D module), analog to digital conversion, into the PLC, touch screen control PLC for data calculation and processing, complete control and protection equipment output. The entire system with touch screen interface to control underground drainage system, determination of main equipment selection: Mitsubishi FX2NC-32 MT PLC controller and touch screen to select the Beijing Kunlun state Software Development Co., Ltd. developed embedded mechatronics touch screen mcgsTpc The model TPC7062 K equipment control system with the contemporary level of advanced technology.The design system is reliable,easy to operate, high degree of automation, human-machine interface is intuitive,practical application of high value.This topic using the Mitsubishi programming software development and design of control procedures, including: analog data processing, data conversion program,PID control procedures, operational control procedures, fault protection procedures.Beijing Kunlun-state embedded mechatronics touchscreen mcgsTpc, face the water supply system was developed to control the interface, Include: start and stop control interface, the water level monitoring interface, the pressure detection interface, speed power interface flow control interface, fault protection interface, The system is running a full range of monitoring, to ensure that the project has a high level of automation.
