Test Method and Test System Development for Key Seismic Indicators of eSeis Neo Node Instrument
Wireless node instrument has been the mainstream core equipment for seismic survey.The key seismic indicators of node equip-ment reflect the level and quality of node equipment,and are directly related to the quality of seismic data acquired and the final imaging effect.Due to the"blind acquisition mode"of node instrument,performance indicators test and quality control of wireless node equipment are the important measure to guarantee the performance of node equipment and the quality of seismic data.In this paper,eSeis Neo test sys-tem with independent signal sources for high-precision seismic indicators test is well designed,which can test thousands of nodes test in par-allel.The test principle,test content and test process for key indicators of eSeis Neo nodes are explained in detail.The characteristics,de-sign scheme,software and hardware structures and implementation methods of the node test system are described.Furthermore,an in-depth discussion about the optimization design for multi-node high-precision seismic indicators test with independent signal sources is presented.Currently the eSeis Neo nodes and the test system have achieved mass production and large-scale applications.The performance of the tested nodes is stable and reliable,the seismic data sampled is of good quality,and favorable comments are received from Party A.The indicators of the test system have been certified by the third-party institution.
