摘要
给出了一种用于煤炭自燃定位的WSN设计,讨论了传感器节点的设计原则,重点研究了节点的硬件结构,并详述了网络协议。定位系统的核心部件由MSP430微处理器、CC2420射频芯片、DZW-T1温度传感器等组成,网络层采用多路径负载均衡技术的路由机制,数据链路层选择S-MAC协议。与传统的监测系统相比,设计的系统结构灵活、可扩展性强、测量准确,为煤炭自燃火源定位技术研究拓宽了方向。
WSN for fire source position of spontaneous combustion in coal mine is designed. The design principles of sensor node are discussed. The emphases are put on sensor nodes structure and communication protocol. The position system consists of MSP430 CPU, CC2420 RF chip and DZW- T1 temperature sensor. Multi -path load balancing protocol and S - MAC protocol are used in network layer and data link layer respectively. Compared with traditional monitoring system, WSN is more suitable for colliery security system because of flexibility, extensibility and exact data. The study developed technology of positioning fire source of coal spontaneous combustion.
