Description

technical field [0001] The invention belongs to the field of seismic wave acquisition, in particular to the seismic wave acquisition of a wireless ad hoc network, in particular to a high-precision wireless ad hoc network seismic collector. Background technique [0002] Seismic survey method is an important method frequently used in surveying subterranean structures in related fields such as oil, natural gas or mineral deposits, and seismic survey is generally realized by seismic instruments. In recent years, with the expansion of the scale of seismic survey, the number of seismic instrument field construction has increased, the construction surface conditions have become more and more complex, and the requirements for construction efficiency have become higher and higher. However, the acquisition channels of traditional seismic instruments are connected by cables. Therefore, a large number of workers are required to perform on-site wiring before construction, and the lines n...

AI Technical Summary

Problems solved by technology

However, the acquisition channels of traditional seismic instruments are connected by cables. Therefore, a large number of workers are required to perform on-site wiring before construction, and the lines need to be taken up after the measurement is completed. The work efficiency is low; when encountering highways, railways and water systems , the wiring of wired seismic instruments becomes a difficult problem

Therefore, when conducting seismic surveys in complex terrain, a seismic collector for wireless data transmission is needed to collect and transmit data. However, there are relatively few wireless seismic collectors in the prior art, and the accuracy is relatively low. The processing cannot meet the needs of the analysis
