In recent years,with the gradual scaling of high-precision exploration technologies,both the number of node devices invested in individual projects and the application ratio of projects which using node system have shown an increasing trend.Based on the introduction of the current status of node system,this paper analyzes the main influencing factors and component of the data acquisition circuit.Finally,this paper elaborates on the design ideas for low-power consumption data acquisition circuit of node instruments from the aspects of key com-ponent selection,hardware circuit design,and firmware low-power optimization,and provides specific verifica-tion examples,aiming to provide reference for the future development and manufacturing of node instruments with smaller size,lighter weight,and better overall technical performance.
