Short summary
The nonuniqueness of geophysical inversions, which is based on a single geophysical method, is a long–standing problem in geophysical exploration. This paper developed a distributed, multi–channel, high–precision data acquisition system. It can achieve high–precision hybrid acquisition of seismic–electrical data and monitor the real–time quality of data acquisition processes using NB–IoT technology. The equivalent input noise is 0.5 μV and the synchronization accuracy is within 200 ns.
