基于现场总线的局扇监测控制系统研究
摘要
矿用局部通风机(局扇)是煤矿井下局部通风不可缺少的重要设备,使用量大、应用范围广,承担着为采掘工作面提供新鲜风流、排出有毒有害气体和粉尘、改善作业场所环境条件等重要任务,其工作可靠性直接影响着煤矿的安全生产和经济效益。局扇一旦停止供风或出现故障而没有得到及时处理,将会对煤矿安全生产和矿工人身安全造成严重影响。因此建立针对局扇的监测监控系统,对局扇进行实时监测和远程监控,以便随时了解局扇的运行状态并及时排除故障,具有重要的现实意义。
现场总线是一种数字式、串行、多点通信的开放数据总线,它的出现实现了现场设备的彻底分散控制。LonWorks现场总线具有网络结构灵活、传输介质开放、可以主从方式工作、实时性强、节点多、传输速率高、可利用同一电缆向现场设备供电和传输信号、具有本质安全型防爆产品等优点,是一种很有发展前景的现场总线。将LonWorks现场总线应用于局扇监测监控系统,以充分发挥LonWorks现场总线的优点对局扇进行更好的监控,正是本文的任务所在。
论文结合目前煤矿局扇监测监控系统的发展现状,综合运用LonWorks先进技术及组态软件的优越性,开发设计了基于LonWorks现场总线的局扇监测监控系统。论文介绍了现场总线的发展概况及LonWorks现场总线的核心技术,探讨了LonWorks应用于煤矿监控的可行性和优越性,在此基础上构建了以LonWorks现场总线为通信网络的局扇监测监控系统,并对该系统的结构、方案、功能和主要技术指标进行了论述。智能节点承担着现场数据采集、处理和传输的重要任务,是下位机设计的重点,本文着重介绍了智能网络适配器的设计。上位机的设计采用组态软件,具有控制功能丰富、组态灵活、扩展方便的优点。以DDE的方式实现了上位机和下位机智能节点之间的通信,并完成了上位机与下位智能节点间的通信程序编写工作。本文采用LonWorks现场总线作为通信网络,克服了传统煤矿DCS监控系统传输模拟信号、协议封闭等弊端,具有很好的应用前景。
Mine local fan, which is an indispensable equipment for tunneling ventilation underground mine, is largely consumed and widely applied, and undertakes important tasks of providing fresh airflow for extracting coal face, exhausting toxic harmful gas and dust and improvimg operating environment. Its working reliability directly influences prduction safety and economic benefit. Just in case, local fan stop it's wind or go wrong without treatment timely, which will badly threaten coal safe production and coal workers' person safety. Therefore, it has important realistic meanings that mine local fan is real-time monitored and remote controlled to know its operating state in any time and clear fault in time.
FieldBus realizes thoroughly distracting control of local equipments, which work as a sort of digital, serial, multi-node and open databus. LonWorks has many virtues,such as flexible network,open transmit medium,principal and subordinate work,strong realtime,more nodes,high speed,having essence safety productions,etc.It is a kind of fieldbus having good foreground. It is the article's main task to apply LonWorks to local fan monitoring and controlling system in order to sufficiently distribute LonWorks' advantage.
The local fan monitoring and control system based on LonWorks is developped, with development status of local fan monitoring and control system considered and advanced LonWorks technology and configuration software applied .The development state of field bus and the core technology of LonWorks field bus are introduced, and the feasibility and advantage of LonWorks being applied for mine monitoring are indicated, and based on it, local fan monitoring and control system of LonWorks field bus as communication network. At the same time, its structure, proposal, function and main technical index are discussed. Intelligent node takes it's hand to gather、deal with and transmit data etc, which is the emphasis of the lower computer design. The design of intelligent network adapter is especially introduced. Configuration software is adopted in host computer design, which has the advantages such as abundant controlling ability, flexible configuration and convenient enlargement. Last, network communication management software is designed by DDE way achieving lower configuration software.The design of host computer's monitoring part and the design of system communication management is main in the paper. The system adoptes LonWorks field bus as communication network that is a open bidirectional serial mutipoint communicative digital network. It overcomes the faults of traditional mine DCS monitoring system transmiting analog signals, protocol enclosing, etc. and has good application prospect.
