【摘要】:當(dāng)前節(jié)點(diǎn)定位基于節(jié)點(diǎn)通信鄰域內(nèi)鄰居節(jié)點(diǎn)的個數(shù)估算節(jié)點(diǎn)間距,對運(yùn)行環(huán)境有高,難以廣泛使用于礦震監(jiān)測,為此提出基于激光的分布式礦震監(jiān)測系統(tǒng)中的節(jié)點(diǎn)定位方法。首先對上位機(jī)和下位機(jī)與CAN總線間邏輯進(jìn)行論述,了解節(jié)點(diǎn)數(shù)據(jù)采集過程,然后根據(jù)上位機(jī)和下位機(jī)與CAN總線之間邏輯,完成對RSSI測距模型優(yōu)化,計(jì)算RSSI信號濾波,從而完成RSSI定位模型的構(gòu)建,實(shí)現(xiàn)基于激光的分布式礦震監(jiān)測系統(tǒng)中節(jié)點(diǎn)的定位。實(shí)驗(yàn)結(jié)果表明,該方法能夠有效提高分布式礦震監(jiān)測系統(tǒng)中節(jié)點(diǎn)定位的準(zhǔn)確性,提高分布式礦震監(jiān)測系統(tǒng)中節(jié)點(diǎn)定位速度,具有較好的使用價值。
[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.

【正文快照】: 分布式礦震監(jiān)測系統(tǒng)是保證煤炭開采安全的重要手段,越來越受到人們重視[1-3]。分布式礦震監(jiān)測系統(tǒng)中的節(jié)點(diǎn)定位能力直接影響系統(tǒng)性能。為了提高分布式礦震監(jiān)測系統(tǒng)中的節(jié)點(diǎn)定位準(zhǔn)確度,有學(xué)者提出了基于多跳導(dǎo)標(biāo)節(jié)點(diǎn)的分布式礦震監(jiān)測系統(tǒng)節(jié)點(diǎn)定位方法[4-6],并在此基礎(chǔ)上提出了
