摘要： 为减少或避免选煤厂瓦斯爆炸事故的发生,解决选煤厂安全监控系统智能化程度低和不能精准地确定瓦斯质量浓度这一问题,引入无线传感器网络(WSN)进行监控,设计安全监控系统框架和各功能单元,分析验证其应用性能;分析选煤厂安全智能监控领域WSN的应用价值。系统运行中可以基于大量的传感器节点进行信息采集,将相关信息通过通信网发送到控制中心。结果表明:WSN可以实现选煤厂瓦斯质量浓度的实时检测,达到预警值现场报警,确保在出现警情后高效的应对,从而为瓦斯质量浓度的监控提供支持,避免引发严重事故。采用的低功耗分群分层路由协议,可延长网络的有效生命周期,使各节点能量损耗均衡。

Abstract: In order to reduce or avoid gas explosion accidents in coal preparation plants and solve the problems of low intelligence of its safety monitoring system and inability to accurately determine mass volume concentration of gas, WSN was introduced, framework of the monitoring system and its functional units were designed, and its application performance was analyzed and verified. Then, application value of WSN in intelligent safety monitoring of such plants was analyzed. During the systems operation, information could be collected based on a large number of sensor nodes and sent to control center through communication network. The results show that WSN can realize real-time monitoring of gas concentration in coal preparation plants and provide early warning on site when it reaches certain value, which could ensure efficient response after alarm, so as to provide support for gas monitoring and avoid serious accidents. The low-power clustering and hierarchical routing protocol can prolong effective life cycle of the network and balance energy loss of each node.

Key words: coal preparation plant, safety monitoring, gas mass concentration, wireless sensor network (WSN), catalytic combustion
