Abstract

The invention discloses a data collecting apparatus for cathodic protection, which comprises a CPU (central processing unit) used for sampling a voltage and / or current, a data memory used for storing the voltage and / or current acquired by multiple sampling of the CPU, and a wireless communication unit used for sending the voltage and / or current acquired by sampling to a data central server with an appointed IP (internet protocol) address. The invention also discloses a monitoring management system and a monitoring method for cathodic protection. The invention can realize the centralized monitoring and managing of running parameters and protection effect of an electric method protection system for a pipeline, guarantee reliability and authenticity of cathodic protection effect testing data, effectively improve running management level of cathodic protection, and lower managing and running cost of the cathodic protection system. The data collecting apparatus provided by the invention has the advantages of simple circuit design, reliable performance and low cost. The invention also sufficiently considers field use conditions, is suitable for field requirement and is convenient to install and manage.

Description

technical field [0001] The present invention relates to the technical field of cathodic protection in electrochemical protection, and the application of data acquisition, GPRS wireless data transmission and data processing technology in the technical field of cathodic protection, in particular to a cathodic protection data acquisition device, a monitoring management system and its monitoring method. Background technique [0002] The anticorrosion of buried pipelines (structures) mostly adopts the relatively mature technology of cathodic protection at present. However, in the actual operation process, the quality of the protection effect comes from the timely and correct monitoring of the cathode potential. Traditional cathodic potential monitoring methods use periodic manual measurements. Due to the wide distribution area of ​​the pipeline and the complex and changeable geographical environment along the line, it not only wastes a lot of manpower, material resources and fi...
