热轧托盘运输二级控制系统概述

Level- two Control System Analysis on Hot Rolling Stock - transport

首钢京唐钢铁厂1580mm热轧成品钢卷运输采用双排式托盘运输方式，该托盘运输线由我公司自主设计承包。托盘运输自动化控制系统由我公司自动化专业设计研发。二级控制系统是自动化系统的核心部分，运输线二级系统作为热轧生产线自动化系统的一部分，通过同轧线二级自动化系统、托盘运输一级自动化系统、工厂三级自动化系统、喷号机等外设系统的通讯，接收和发送数据，完成对运输线上被跟踪目标（托盘、钢卷）的实时位置跟踪和数据跟踪（数据记录与备份），同托盘一级自动化系统相结合完成对双排式托盘运输系统自动化的控制。其中数据通讯的安全性和稳定性是整个控制系统正常工作的前提。目前该托盘运输系统运行正常，满足实际生产要求。

Side - by - side stock transport is used for Shougatag ~ingtang Steel Ltd. Roiling transport line. This line is Engineering and Procurement（E-P） project on my company. The control system is studied by automation major. The Level - Two system, the key of the control, is connected with the Rolling Level - Two, the transport line Level -One, the Level- Three, the Printing machine. All of Them finish the control of transport line by sending and accepting data each other. Precondition of control system is the security and reliability of data - communication. Now, the transport line run in security.
