Power supply heat exchange control device for seismic exploration

Abstract

The invention discloses a power heat exchange control device for seismic exploration, which comprises a main power circuit unit, a backup power circuit unit, a voltage acquisition circuit unit, a power supply circuit unit, and a management control circuit unit; the main power circuit unit can be used for loading The battery also outputs electric energy to the outside; the backup power supply circuit unit is used to output electric energy to the outside; the voltage acquisition circuit unit includes a first voltage acquisition circuit, and the first voltage acquisition circuit is used to acquire the voltage value of the main power supply circuit unit; the management control circuit unit, It is used to receive the voltage value of the voltage acquisition circuit and send a control signal; the power supply circuit unit is used to provide the electric energy output by the standby power supply circuit unit to the management control circuit unit. The invention can prevent the Hawk system collection station from restarting the built-in system of the collection station due to the replacement of the external lithium battery. At the same time, it can also turn off the power supply output of the backup power supply circuit unit by timing, so as to avoid the use of the backup power supply circuit unit when the collection station needs to be shut down.

Description

technical field [0001] The invention relates to the field of seismic exploration, in particular to a power supply heat exchange control device for seismic exploration. Background technique [0002] With the deep development of geophysical exploration to the number of roads and high-density acquisition, the exploration methods are becoming more and more diverse. In particular, the high-precision seismic exploration method of "two widths and one height" has been accepted by more and more oil companies. The emergence of technology and new methods has higher requirements for seismic exploration instruments. In order to break through the limitations of conventional wired transmission seismic exploration instruments, geophysical instrument manufacturers have launched new products one after another, and the node seismic instrument is one of them. [0003] The Hawk system is a nodal seismic data acquisition system launched by INOVA. Its main feature is that each data acquisition st...
