梅钢1420酸洗-冷轧联合机组是国内第一条依靠自己的力量进行自主集成的冷连轧生产线，其工艺和设备具有世界一流水平，尤其是其三电控制系统(EIC)的集成具有自己的特点，该系统采用了先进、成熟、可靠的三电系统配置和控制技术，该三电一体化控制系统由二级过程计算机控制系统（L2）、一级基础自动化控制系统（L1）、操作监控系统（HMI）、网络设备以及现场检测元件和电气执行设备(L0)组成。本文重点阐述三电控制系统构成特点，网络系统和L2及L1的控制功能。

This self-integration of Meishan 1420 pickle line coupled to tandem mill plant is the first project carried out on its own EIC control system integration. Its technology and equipment with a world-class standard, its EIC control system uses an advanced, mature and reliable EIC configuration and control technology. The ECI control system consists of processes integrated computer control system (referred to as L2), a basic automation control system (referred to as L1), operations monitoring system (HMI), network equipment and on-site inspection sensors and the implementation of electrical equipment (referred to as L0).Here focuses on the ECI control system configuration, introduction composition of network system, L2 and L1 control function.
