【摘要】 现场总线技术、嵌入式技术和电子技术的快速发展,为我国矿井生产自动化的跨越式发展提供了契机。基于现场总线的矿井自动化系统,不仅成本低、监控能力强,而且现场设备的智能化程度高,因此研究基于现场总线的矿井监控系统具有很现实的意义。矿井运输监控是煤矿安全监控系统中的重要组成部分,本课题致力于基于CAN现场总线的矿井智能轨道测控模块研究,用嵌入式技术改造两类重要的现场设备——计轴器和转辙机,组成独立的轨道测控系统,实现了对矿井轨道运输中相关设备的数据的采集及智能控制。论文研究了计轴器和转辙机的功能需求,针对它们的功能需求设计完成了一套计轴器信号采集处理和转辙机安全驱动软件。论文结合整个运输监控系统的特点和对模块的要求,设计确定了计轴器采集模块和转辙机控制模块的CAN总线的应用层协议。针对矿井的恶劣的使用环境,论文通过采用了一整套包括指令冗余技术、数字量多次读入法、看门狗技术等方法,有效的提高了系统的抗干扰能力,解决系统的安全性和可靠性问题。论文最后针对两个智能模块的实际使用要求,建立各种软硬件仿真测试平台,对系统的功能进行了全面的调试,经过调试和改进,在实验室的环境下,计轴器采集模块和转辙机控制模块都达到了设计的要求。更多还原

【Abstract】 The rapid development of Fieldbus technology、Embedded technology and electronic technology provide an opportunity for the leapfrog development of mine production automatization in China. Automantic control system based on Fieldbus system not only has low cost and strong monitoring capability, the field device of system also has high intelligent degree. So the research based on Fieldbus mine monitoring system has very realistic significance.Mine transport monitor is an important component of mine monitoring system. This case concentrated on the research of intelligent mine track monitor&controlmodules based on CANbus, improved two kind of important field equipment--axle counter and switcher through embedded technology, set up an independent track monitoring system and realized intelligent control and data acquisition of related devices in mine track transport.The thesis researched the function and demand of axle counter and switcher. To meet their function and demand, the thesis designed axle counter signal acquisition driver software and switcher safe driver software.According to characters of whole system and modules, the thesis set down the communication protocol to application layer of two intelligent modules.To meet rough environment of coal mine, the thesis designed a set of suitable software anti-jamming methods include watch dog and the redundancy instruction and repetitious read number to solve safety and reliability problems in the system.Finally, to meet the needs of practical use, the thesis established software and hardware simulation test platforms of two modules, test and debugged the system functions comprehensively. After debugging and improving, the axle counter acquisition module and the switcher control module achieved the design requirements in lab circumstance.更多还原
