摘要
针对目前煤矿巷道离层监测大多为有线监测的现状,设计了一种基于WSNs的煤矿巷道离层监测系统。介绍了系统的整体架构,详细阐述了以CC2430为核心的传感器节点、以CC2430和MCP2515为核心的Sink节点的软硬件设计和工作流程。通过矿井下实验,测得了2.4 GHz频率在井下的传输特性,并确定井下2只无线传感器节点的距离为15 m时,可实时、可靠地监测巷道的离层情况。
A roadway abscission monitoring system based on WSNs is designed, aimed at the state of lineate most coal mine roadway abscission layer monitoring at present. The stucture of the system is introduced and also the software and hardware designs and the work process which uses CC2430 as the sensor node and uses CC2430 and MCP＇2515 as the core of the sink node. Through the underwell experiments in coal mine, the transmission characteristics at 2.4 G is determined. The abcission layer status of the roadway under-well is determined real-time and reliable ,while the distance between two wireless sensor nodes is 15 meters.
