摘　　要：为解决现有煤矿安全监控系统对基于CAN总线、RS485等不同总线协议的矿用分站节点的调度问题,提出将信息物理系统(CPS)技术引入煤矿井下,建立能够兼容工业以太网、各种现场总线分站和设备仪器的分布式混合系统模型,构建有效消除安全隐患的风电瓦斯闭锁系统。阐述了基于CPS的风电瓦斯闭锁系统的总体结构和功能设计,分析了基于时间并发性建模的方法,并使用PtolemyⅡ混合系统并发模型设计工具实现系统建模。最后,针对瓦斯喷出和瓦斯突出2种情况,使用MATLAB工具对系统性能进行仿真分析。结果表明,该模型能够应对瓦斯涌出突发事件,通过触发通风机控制系统,将矿井瓦斯浓度快速有效地调节在安全范畴。In order to solve the dispatching problems of the mine substation nodes in the mine available safety monitoring and control sys- tem based on the CAN bus, RS485 bus and other different bus protocols, the information physics system technology was introduced to the underground mine. A distribution mode mixing system model compatible with the industrial Ethernet, different site bus substation and the equipment instruments was established. A ventilation, electric power and gas interlock system effectively to eliminate safety dangers was established. The paper introduced the general structure and function design of the ventilation, electric power and gas interlock system based on CPS and analyzed the modeling method based on the time simultaneity. The simultaneity model design tools of the Ptolemy Ⅱ mixing system were applied to realize the system modeling. Finally, according to the gas blowing and the gas outburst conditions, the MATLAB tools was applied to the simulation analysis on the system performances. The results showed that the system could be capable to deal with the gas emission and outburst accident and could be rapidly and effectively to control and adjust the mine gas content within a safety scope.
