Node location in distributed mine earthquake monitoring system based on laser

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。

Current distributed mine earthquake monitoring system has a large demand for operating environment and is difficult to be widely used.In this paper,a method of node location in distributed mine earthquake monitoring system base on laser is proposed.First,the logic between the host and the lower computer and CAN bus is discussed.The process of node data acquisition is discussed.Then,complete the RSSI distance model optimization according to the logic of the host and the lower computer and CAN bus.Calculate the RSSI signal filtering to complete the construction of RSSI positioning model,finally achieve the nodes location through laser-based distributed mine earthquake monitoring system.The experiment shows that the proposed method can effectively improve the accuracy of node location and the positioning speed of nodes in distributed mine seismic monitoring system,and has good usage value.
