在分析传统煤矿井下安全监测和人员定位的基础上,提出了基于ZigBee的煤矿安全监测及人员定位于一体的系统设计方案。设计了系统体系结构,并详细设计了节点的软硬件。系统通过安装在节点上的传感器采集井下环境数据,采用基于固定节点间距离的校正模型进行人员定位,并将采集的信息通过以太网传输到井上监控主机,实现对井下环境和人员位置的实时监控,对煤矿安全监测和事故抢救具有重大意义。
Based on the analysis of the safety monitoring and personnel positioning in the traditional coal mine, a systematic design scheme of coal mine safety monitoring and personnel positioning based on ZigBee is proposed. The system architecture is designed and the hardware and software of nodes are designed in detail. The system collects the underground environment data through the sensor installed on the node, uses the calibration model based on the fixed node distance to locate personnel, and transmits the collected information to the uphole monitoring host via Ethernet to realize the real-time monitoring of underground environment and personnel position It is of great significance to mine safety monitoring and accident rescue.
