Design of Automatic Feeding Control System in Tank Area Based on WinCC Configuration Software

摘要

With the advancement of science and technology and the rapid development of microelectronics technology, programmable logic controller (PLC) has been widely used in the automation field of the chemical industry. This paper design a system is based on Siemens PLC S7-1500 module, the main control unit is CPU1515-2. The tank area and 4 production workshops are networked to realize automatic transportation of 9 different materials. With the host computer configuration software Windows Control Center(WinCC), the process parameters such as data overview, flow chart, curve, alarm window and so on are displayed on the man-machine interface, real-time monitoring is realized, and the amount of material is automatically stored in the SQL Sever 2012 database. Simplify process analysis and production management. Compared with the traditional manual feeding method, this method can improve the accuracy and stability of the production process, keep employees away from the scene, reduce the possibility of accidents, and reduce time costs.
