文档介绍：摘要
自动布料控制系统主要包括矿仓料位检测与控制;布料小车位置检测与控制;以及对相关设备实施逻辑连锁与保护控制,确保整个系统安全、稳定、高效的运行。在焦化配料过程中,配煤仓出现混煤对产品质量有着直接的影响。目前大多数焦化厂配煤布料系统中布料方式都是布料工人实现布料,极易造成混煤和堵料斗等质量事故。针对传统的布料形式的弊端,设计出高效稳定的自动布料控制系统显得尤为的重要。
本自动布料控制系统以炼焦厂煤的自动布料为主体工艺,采用PLC为核心处理器,结合电气控制技术、检测技术将现场所有控制设备构建为分布式系统,通过软件编程和软硬件组态技术实现自动布料的现代化监控与管理。开发出性能优良的、适用于各型焦炉的PLC控制系统;控制系统包括布料小车位置检测系统、料仓料位检测系统、信号的处理及传输和布料小车连锁控制系统。

ABSTRACT
Automatic distributing control system mainly includes the material level in ore bins detection and control; Cloth car position detection and control; And the related equipment implementation logic chain control and protection, to ensure the system safe, stable and efficient operation. Appeared in the process of coking ingredients, with coal blended coal has a direct affect the quality of product. Currently most coking plant blending cloth fabric information in the system are workers achieve cloth, cloth is easily mixed coal and quality accidents such as wall hopper. Aimed at the disadvantages of traditional forms of material, design of efficient and stable automatic distributing control system is particularly important.
This automatic control system to coking plant coal automatic fabric cloth as the main body craft, USES the PLC as the core processor, combined with electric control technology, detection technology will build field all control equipment for the distributed system, through the software programming and hardware and software configuration technology to realize the modernization of the automatic cloth monitoring and management. Develop excellent performance, suitable for various types of coke oven of PLC control system; Control system including cloth car position detection system, bin material level detection system, signal processing and transmission and cloth car chain control system.
Keywords Material position detection, reversible belt, PLC, electric control
