综合自动化企业的建立是我国加快实现现代化和工业化的必经之路,以信息化带动工业化,以工业化促进信息化,这是本世纪我们经济建设和改革的主要任务之一,也是一个长期的战略。随着煤炭工业的发展和体制改革的深入,传统的选煤生产管理模式已不能满足现阶段煤炭企业生产管理的需要,迫切需要引进一种现代化和数字化的生产管理理论和方法。这就在客观上要求建立一种综合自动化的平台,以便保证选煤的安全生产,快捷方便地进行煤质管理和高效地指挥调度,进而提升煤矿企业效益,加快企业发展步伐,增强市场竞争力。本设计正是为完成此目的。
综合自动化建设是指企业利用现代的信息技术,通过对信息资源的深度开发和广泛利用,不断提高生产、经营、管理、决策的效率和水平,从而提高企业经济效益和企业竞争力的过程。一个完善的综合性信息化管理体系,依托于高精度、智能化的现场数据处理系统,准确无误的通讯手段传输信息和高效快捷的计算机处理信息。S7-300系列PLC是选煤厂的综合自动化设计的核心信息处理单元,现场采集信息需经过PLC处理后返回现场执行机构 ,PLC和分布式I/O(DIO)站采用Profibus网络连接,PLC之间通过冗余以太网进行相关设备的数据交换。本设计实现功能包括:低压配电系统自动化、生产工艺自动化、底层设备智能化巡检、数据网络系统的建设以及基于WEB的综合信息化管理系统。这几部分从底层生产设备控制到上层软件信息管理,整体性地构建起了一个综合信息化的选煤厂。
选煤厂的综合自动化设计建设完成了生产过程中自下而上的信号采集、传输和自上而下的控制、管理,实现选煤生产的安全、高效、便捷。

The establishment of the comprehensive automation of enterprise is a necessary choice to speed up the realization of industrialization and modernization in our country, insisting on informatization to drive industrialization, industrialization promotes informatization, this is our main tasks of economic construction and reform of this century, and also a long-term strategy. With the development of coal industry and the deepening of the reform, the traditional coal production management pattern already cannot satisfy the need of present coal enterprise production and management, it is an urgent need to introduce a modern, digital production, management theory and methods. It is objectively required to establish an integrated automation platform, in order to ensure the safety of coal production and quality management, as well as efficient scheduling command and raising efficiency of coal mining enterprises. Then they can speed up the pace of enterprise’s development and enhance market competitiveness. This article is to achieve it.
Comprehensive automation means the enterprise continuously improve the efficiency of the production, management, decision and level by using modern information technology, and depth development and widely use of information resources, so as to improve the process of enterprise economic efficiency and competitiveness. A perfect comprehensive automation management system depends on the data processing system of high precision, intelligent, accurate and efficient means of communication transmission information and fast computers to process information. S7-300 series of PLC is the core of the information processing unit of the design. PLC connects with distributed I/O(DIO)using Profibus, and exchanges data coming from the related equipments with each other using redundant Ethernet. 《Comprehensive automation design of coal preparation plant》including: Automatic control of low voltage power distribution system, automatic control of production process ,intelligent inspection, data network system, Integrated information management system based on WEB. The several parts compose a coal preparation plant with comprehensive information, from the equipment of the bottom to the upper information management system.
The design of comprehensive automation of coal preparation plant realizes the production process of bottom-up signal collection, transmission and top-down control and management, making it safe, efficient and convenient.
