Description

Penetration and extraction control circuit of submarine sediment probe rod

Technical Field

The invention belongs to the technical field of marine geophysical research engineering, and particularly relates to a penetration and extraction control circuit of a submarine sediment probe.

Background

With the continuous development of economy and society and the increasingly outstanding contradiction of environmental protection, the development of ocean resources and the inability to destroy the ecological environment have become an urgent issue. In recent years, the importance of the country on the development and utilization of ocean resources has grown year by year, from ocean biological resources to ocean mineral resources, from ocean energy sources to ocean space resources, and none of the country and people are precious properties. However, the desire for resources by humans is blind. In the nearly crazy resource exploitation process, humans hardly recognize how the behavior of themselves can cause harm to the ecological environment. Pollution caused by harmful substances entering the marine environment can damage biological resources and in turn human health. Reasonable exploitation of marine resources is an extremely important criterion for both humans themselves and for the marine ecology environment. Currently, the monitoring time of the submarine environment monitoring device for the submarine environment is often limited, and for the monitoring for a long time, the power consumption of the power supply device is either depleted, the system is unstable in operation, or a series of other factors, so that the long-time detection cannot be supported. While short-time monitoring devices can obtain relatively complete subsea environmental data through short-time multiple detections, such devices require multiple deployment and retrieval and obtain only partial data.
