Problems solved by technology

At present, distributed power supply schemes are adopted in small-scale seismic exploration instruments, that is, each station is powered by an external battery, which not only increases the workload of field construction, but also reduces the reliability and stability of the system. Therefore, for large-scale seismic exploration The power supply and data transmission of the system must find another solution

Abstract

The invention discloses an active data transmission system for a seismic exploration system. The seismic exploration system is provided with multiple collection nodes connected to a transmission line;the active data transmission system is used for supplying power for various collection nodes of the seismic exploration system, and transmitting data among various nodes; the active transmission system comprises a power supply end and a power receiving end; the power supply end is configured on the former collection node, and the power receiving end is configured on the next collection node, andthe power supply end and the power receiving end have the power module. The active data transmission system for the seismic exploration system performs multiplexing transmission by adopting a way of coupling the power supply and the data, the weight of the data transmission line and the cable core number are reduced; the cable of the seismic exploration system can be saved after the system is saved, the manpower and the material resource are saved, and the system brings great convenience for the field construction.

Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to an active data transmission system for a seismic exploration system. Background technique [0002] Seismic exploration is an effective means to obtain the distribution of underground oil, natural gas and other resources. It is an important means to survey oil and natural gas resources before drilling. It has also been widely used in coal field and engineering geological exploration, regional geological research and crustal research. , in order to detect oil, natural gas and mineral resources in the deep part of the earth, an advanced seismic exploration system with 10,000 or even millions of channels is required. At present, distributed power supply schemes are adopted in small-scale seismic exploration instruments, that is, each station is powered by an external battery, which not only increases the workload of field construction, but also reduces the reliability and...
