[0002] In order to study seawater intrusion more deeply, more and more high-density resistivity probes are deployed in the offshore for long-term observations. Currently, among a series of high-density resistivity probes that have been deployed, manual switching of probes is often required. , monitor the resistivity of the seawater between the probes, or monitor the resistivity of the seawater between the probes in turn according to the deployment situation, which cannot realize the intelligent monitoring of the resistivity of the seawater between the probes according to the needs of professionals; on the other hand, the current Most high-density resistivity probes use a single-way switch control circuit, so the entire control system requires more control circuits and consumes more power, which is not conducive to long-term seawater intrusion observation

The invention provides a multi-path change-over switch control circuit for a high-density resistivity probe. The multi-path change-over switch control circuit is composed of a power supply circuit, a change-over switch control circuit, a serial port communication circuit and a main control circuit. Four channels of one same high-density resistivity probe are controlled by using a multi-path switching control chip, thereby realizing random switching of four channels. Moreover, the scheme can be applied to multiple high-density resistivity probes widely, so that the sea water resistivity between probes can be detected according to demands of professionals and thus the sea water intrusion phenomenon can be found out timely. Compared with the background technology, the invention provides an effective method for realizing offshore long-time observation of a sea water intrusion phenomenon, so that professionals can obtain sea water intrusion information timely.
Description
technical field [0001] The invention belongs to the category of integrated switch control circuits in the technical field of ocean observation, and in particular relates to a multi-channel switch control circuit for high-density resistivity probes. Background technique [0002] In order to study seawater intrusion more deeply, more and more high-density resistivity probes are deployed in the offshore for long-term observations. Currently, among a series of high-density resistivity probes that have been deployed, manual switching of probes is often required. , monitor the resistivity of the seawater between the probes, or monitor the resistivity of the seawater between the probes sequentially according to the deployment situation, which cannot realize the intelligent monitoring of the resistivity of the seawater between the probes according to the needs of professionals; on the other hand, the current Most high-density resistivity probes use single-way switch control circuits...
