Research on field efficient positioning and tracking technology of Bluetooth nodal seismometers
At present,the nodal seismometers have been widely used in seismic acquisition projects.This king of instrument improves acquisition efficiency greatly,but also brings about the problem of easy to loss and difficulty in finding in field.Especially when nodal seismometers encounter tilting,occlusion,theft and concealment,the signal is weak or cannot provide coordinate information at all,and the cost of manual search is high and the effi-ciency is low.In response to the above issues,this article proposes a technical solution for positioning and trac-king lost Bluetooth type nodal sseismometers in the field,which comprehensively utilizes technologies such as drones,radio,and ground air synchronization,to replace manual search mode,in order to achieve fast and effi-cient retrieval and reduce search costs.The paper explores in detail how to use the wireless physical characteris-tics of Bluetooth signals,as well as mathematical spatial analysis geometric tools,combined with a series of tech-nologies such as drones,to form a'triangulation directing and cross positioning'method to achieve efficient posi-tioning and tracking of lost Bluetooth type nodal sseismometers in the field.
