基于PLC的带式输送机智能保护系统设计

Design of Intelligent Protection System of Belt Conveyor Based on PLC

  • 摘要: 针对国内现有矿井带式输送机保护系统功能单一、可靠性低、系统集成性与扩展性差等问题,结合煤矿带式输送机的常见故障类型,提出了一种基于PLC的带式输送机智能保护系统,介绍了系统硬件结构和软件设计。该系统可独立操控,也可多级闭锁操控;具备良好的通信联网接口,可扩展性强;支持工业以太网传输,具有智能化集控功能。实际应用验证了该系统的可行性和有效性。

     

    Abstract: In view of problems of single function, low reliability and poor integration and expansibility of system in existing protection system of belt conveyor of coal mine, and comparing common fault types of belt conveyor, the paper proposed an intelligent protection system of belt conveyor based on PLC and introduced hardware structure and software design of the system. The system can be operated singly and locked with several levels, has perfect interfaces of communication networking with strong expansibility, supports transmission through industrial Ethernet and has intelligent integrated control function. The actual application verified validity and reliability of the system.
