【摘要】：当前节点定位基于节点通信邻域内邻居节点的个数估算节点间距,对运行环境有高,难以广泛使用于矿震监测,为此提出基于激光的分布式矿震监测系统中的节点定位方法。首先对上位机和下位机与CAN总线间逻辑进行论述,了解节点数据采集过程,然后根据上位机和下位机与CAN总线之间逻辑,完成对RSSI测距模型优化,计算RSSI信号滤波,从而完成RSSI定位模型的构建,实现基于激光的分布式矿震监测系统中节点的定位。实验结果表明,该方法能够有效提高分布式矿震监测系统中节点定位的准确性,提高分布式矿震监测系统中节点定位速度,具有较好的使用价值。
[Abstract]:The current node localization is based on the number of neighbor nodes in the neighborhood communication nodes to estimate the distance between nodes. It has high operation environment and is difficult to be widely used in mine seismic monitoring. Therefore, a node localization method based on laser distributed mine monitoring system is put forward. First carries on the elaboration to the upper and lower machine and CAN bus logic, understand the process node data acquisition, and then according to the logic between the upper and lower machine and the CAN bus, the completion of the RSSI ranging model optimization, calculation of RSSI signal filtering, so as to complete the construction of RSSI positioning model, realize the distributed node location of mine earthquake monitoring system of laser based on the. The experimental results show that this method can effectively improve the accuracy of node location in distributed mine monitoring system, and improve node location speed in distributed mine monitoring system, which has good value in application.
