Abstract
The invention discloses a seabed observation network electrode switching and maintaining system which comprises a master control circuit, a sub-control circuit and an electrode set, wherein the electrode set is provided with one main electrode and two auxiliary electrodes. When the system works, at least one electrode is maintained to serve as the cathode of a seabed observation network to form a major loop with anodes of seawater and a shore base. When many attachments are generated on the surface of the electrode serving as the cathode of the seabed observation network, on one hand, on-and-off states of a normally closed single-pole single-throw relay on the master control circuit are controlled so that different electrodes can be controlled to be switched, and a new switched electrode serves as the cathode of the seabed observation network; on the other hand, on-and-off states of a normally open double pole single throw relay on the sub-control circuit are controlled so that the left two electrodes can serve as an anode and a cathode respectively to form another loop with the seawater to be used for eliminating the attachments on the surface of the electrode serving as the previous cathode. The seabed observation network electrode switching and maintaining system is simple in structure, convenient to operate and capable of improving reliability of a seabed observation network electricity supply system.
