Description

technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to a system for real-time monitoring of a potentiostat in a cathodic protection system. Background technique [0002] With the development of the economy and the construction of the city, the number of buried, underwater and concrete metal pipes and metal facilities is increasing, and these metal pipes and metal facilities are prone to corrosion. In order to prevent corrosion of buried pipelines and improve their service life , cathodic protection is one of the main methods of anti-corrosion at present, and the cathodic protection device is the key equipment of the cathodic protection system. Regional cathodic protection is required for buried metal pipelines and metal equipment with high distribution density in the area [0003] At present, in order to solve the corrosion problems of buried metal pipelines and tank groups, forced current cathodic protection is often...

Problems solved by technology

However, the ordinary potentiostat currently used has only the most basic control functions. During normal work, it is placed indoors, and the relevant technical parameter electrical signals are transmitted to the underground pipelines and test piles by the indoor personnel through wired control; especially When the management personnel manage the various technical parameters in the potentiostat, they need to go to the location where the potentio
