摘　　要：作为煤炭产品中一种重要的品种,块煤质量严重影响着企业的经济效益。为了尽可能降低块煤在入仓时的破碎率,同时提高生产效率,提出了基于PLC的块煤防破碎装车控制系统。结合选煤厂实际情况,设计了系统结构组成。论述了整个系统的工作原理,控制系统构成,可编程控制器接口定义及程序详细流程。系统自动化程度高,防止块煤破碎效果良好,增加了装车的可靠性及灵活性,提高了装车效率,便于生产管理。同时保证了选煤厂的正常生产,显著提高了产品的附加值。As an important species of coal products,economic efficiency of enterprises is seriously affected by the quality of lump coal.In order to reduce fracturing ratio of lump coal during storage process as much as possible,and raise productivity,an anti-fracturing loading system of lump coal based on PLC is proposed.Combining actual situation of coal preparation factory,the system structure is designed,in which the working principle of the whole system,the control system structure,programmable controller interface definition and detail program process are discussed.The system had a high degree of automation and a good effect on preventing lump coal from breaking,meanwhile the reliability and flexibility of loading are in-creased,and loading efficiency is improved as well,which shall facilitate the production management.Moreover normal production of coal preparation factory is ensured at the same time,and product added val-ue is also enhanced significantly.
