井下轨道运输监控系统

井下轨道运输监控系统(中文5000字,英文3000字)
1 摘要
目前，全国各大煤矿企业所采用的井下轨道运输监控系统都有所缺陷，基于此，提出了井下轨道运输监控系统。
文章首先介绍了矿井轨道运输监控系统的历史发展过程，然后对矿井轨道运输的基本理论和外部设备作了说明。最后，给出了系统的整体设计。
该系统是一个由上位机、PLC和以太网交换机以及转辙机、信号机和各种传感器等通过RS-232/RS-485构成的网络系统。
文章重点介绍了PLC的硬件设计和软件设计以及组态的设计。
本系统兼有PLC在轨道运输系统方面的优点和以太网在远距离传输方面的显著特点，具有性能稳定、传输数据可靠、设备成本低、系统扩展灵活等特点。可以应用于各种大、中、小型煤矿的轨道运输监控。

MINE TRACK TRANSPORT MONITORING SYSTEM
1 abstract
At present, the underground rail transport monitoring systems adopted by the major coal mining enterprises have defects, based on this ,the underground rail transport monitoring system  is put forward .
    The article first gives an explanation of the basic theory of mine rail transportation and external devices, and then describes the process of historical development, composition and function of the monitoring system of mine rail transportation.The system is a network system made of PC,PLC ,Ethernet switches switch machines, signals and a variety of sensors via RS-232 / RS-485 .The article highlights the PLC hardware and software design and configuration  design.
    This system both has the advantages of the PLC in the rail transportation system and outstanding features of Ethernet in long-distance transmission , it has stable features, reliable data transmission, low-cost equipment, flexible system expansion, and can be applied to a variety of large, medium and small coal mines rail transport monitoring.
