摘要
针对我国采矿业不断发展,矿震事件不断发生,设计出了一种煤矿监测与定位系统,该系统以STM32F407为主控芯片,通过控制各个模块实现微震源的监测与定位,其中对到达时间差算法(TDOA)进行改进,提出了基于到达时间差的改进布谷鸟搜索算法(TDOA-ICS)的微震定位算法。经过实验验证,TDOA-ICS算法相较于传统TDOA算法定位精度更高,稳定性更强,对于煤矿安全设备研究具有重要的现实意义。
The coal mine monitoring and positioning system has been designed in response to the continuous development of the mining industry and the occurrence of mining-induced seismic events in China.The system is based on the STM32F407 microcontroller,which controls various modules to achieve monitoring and localization of microseismic sources.In this system,an improved time-difference-of-arrival(TDOA)algorithm,namely TDOA-ICS(Improved Cuckoo Search),is proposed.Experimental validation shows that the TDOA-ICS algorithm outperforms traditional TDOA algorithms in terms of higher localization accuracy and stronger stability.This algorithm has significant practical implications for the research of safety equipment in coal mines.
