The design of the ice-out warehouse system base on the S7-300 PLC
Abstract
Winter in the north of china, There is a knot jelly problem when train delivering raw material to factory. Which caused unload a car difficulty, and putting off trains, and serious influence winter raw material supply. Additionally, the large industrial corporations have rich remaining blast furnace coal gas which can make use of. According to ensure the winter raw material smoothly supplies in factory, and to solve rich remaining blast furnace coal gas to put in to air, decreasing pollution of the environment, we must build ice-out warehouse to defrost raw material. In the paper we main introduced the ice-out warehouse system base on the S7-300 PLC. This system mainly involves the knowledge of the PLC system, configuration software, and meter, electric...etc. In the paper, we elaborated the process of the blast furnace gas burning in the burning-furnace, hot-wind forming, and making raw material ice-out in the warehouse. We adopt a traditional PID control a method to control this system. We adopt the configuration soft of WinCC to make control menu on computer as Host, and adopt the autoimmunization flat roof of S7-300 PLC as guest which combined the technique of the electric examination to control temperature of ice-out warehouse. The WinCC connects based on the windows operation system standard, provide software PLC and slot PLC，and it is the production of Siemens company and Microsoft company closely cooperate ,and it is continuously developing. S7-300 PLCs are a traditional PLC of Siemens Company, it aim at medium and low capability control requisition, and it have a high cost performance.
