LonWorks总线技术在瓦斯分布式过程监控中的应用

针对传统主从式瓦斯监控系统性能不佳的问题,提出利用LonWorks技术构建分布式结构瓦斯监控系统。该系统由监控分站、网络控制器和监控中心3层结构组成,监控分站通过网络控制器实现与监控中心的远程通信,完成煤矿瓦斯的现场监控,其由基于Neuron3150芯片的中央控制模块、开关量/模拟量信号通道模块以及LED显示模块构成,主要通过位I/O对象和Neurowire I/O对象实现沟通。整个系统的联动通过网络变量捆绑实现。试验表明,基于LonWorks总线的全分布式结构瓦斯监控系统性能良好。

Application of LonWorks Bus Technology in Distributed Gas Monitoring System

To counter the poor performance of the traditional master-slave gas monitoring system,the distributed gas monitoring system which is based on LonWorks technology was developed.The system is composed of the monitoring sub-stations,network controllers and monitoring center.The remote communication of the monitoring sub-stations with the monitoring center can be realized by the network controllers,thus achieving the field monitoring of coal mine gas.The monitoring sub-stations consists of the central control module which is based on Neuron 3150 chip,the switch / analog signal channel module and LED display module,and the communication was realized mainly by the bit I/O objects and Neurowire I/O objects.The linkage of the entire system was achieved by the bundling of the network variables.The experiments showed that the distributed gas monitoring system based on LonWorks technology has good performance.
