Problems solved by technology
[0004] (1) The traditional detection method adopts the line inspection method, and the professional team detects along the line at intervals, so the data is not continuous and not timely;
[0005] (2) There is no corresponding computer data processing and analysis software for cathodic protection data, and the utilization rate and sharing rate of data are not high, which is not effective in guiding daily pipeline cathodic protection management, which limits the improvement of pipeline management level
[0006] (3) Due to the manual data collection method, the accuracy and reliability of the data are relatively poor, and there are traces of human error

The invention relates to a remote monitoring device for cathodic protection of natural gas pipelines based on a SCADA system, comprising: a data acquisition layer for acquiring real-time working condition data and constant potential real-time working condition data of pipeline monitoring points; a network communication layer for sending data The real-time working condition data of the monitoring points and the constant potential real-time working condition data obtained by the acquisition layer; the remote monitoring layer is used to perform cathodic protection on the pipeline according to the received real-time working condition data Stored in the SCADA system database. Compared with the prior art, the present invention has the advantages of high operability, low maintenance cost and the like.
Description
technical field [0001] The invention relates to a monitoring device for a natural gas pipeline, in particular to a remote monitoring device for cathodic protection of a natural gas pipeline based on a SCADA system. Background technique [0002] The anticorrosion and protection of natural gas underground gas transmission steel pipes is a major issue related to the operation status of pipeline gas transmission, ensuring the safety of natural gas transmission and prolonging the service life of pipelines. It is an important work content of pipeline daily management. [0003] Traditional pipeline cathodic protection detection has the following problems: [0004] (1) The traditional detection method adopts the method of patrolling, and the professional team detects along the line at intervals, so the data is not continuous and not timely; [0005] (2) There is no corresponding computer data processing and analysis software for cathodic protection data, and the utilization rate an...
