At this stage, in the field of seismic exploration, the most widely used equipment with the best application effect is the wired digital acquisition system, but with the improvement of technology, wireless seismic acquisition system and node seismic acquisition system have also started to gradually enter the seismic exploration market, and have completed the seismic data acquisition with high efficiency and high quality in many complex work areas, and have achieved good application effect. SmartSolo was taken as the research object, and the overall architecture, basic working principle and application occasions of nodal seismic data acquisition system from multiple levels and dimensions were introduced in detail.
