Intelligent Cathodic Protection System for Pipeline Anticorrosion with Remote Control & Data Visualization

The Intelligent Cathodic Protection System is an intelligent solution designed specifically for pipeline anticorrosion. As a core component of smart pipelines, it integrates functional modules such as data acquisition, comprehensive analysis, unified regulation, visualized digital twin, and terminal management to realize full-process intelligent control of cathodic protection. It is applicable to scenarios like long-distance oil and gas pipelines, regional compressor stations, and oil-gas transfer stations, solving the pain points of traditional anticorrosion that relies on manual work and has delayed response.

Features:
1. Based on multi-point OFF potential monitoring and neural network algorithms, it intelligently adjusts power supply output, achieving a protection rate of 100% and avoiding over-protection or insufficient protection.
2. It automatically and continuously collects CP parameters along the pipeline, with data accessed to the system in real time and driving algorithm optimization; data utilization rate is 80% higher than traditional manual collection.
3. Adopting 3D dynamic visualization technology, it intuitively displays multi-dimensional anticorrosion parameters without manual form sorting, improving operation and maintenance efficiency by 50%.
4. It supports remote control of test stations and cathodic protection power supply equipment, reducing on-site manual operations by 90% and lowering operation and maintenance costs.

1. Intelligent Power Supply Regulation Technology: Based on multi-point OFF potential monitoring and neural network algorithms, it realizes AI-driven control of cathodic protection power supply output. Compared with traditional single-point ON potential monitoring, the regulation accuracy is improved by 30%, which can adapt to pipeline anticorrosion needs in real time and avoid energy waste.

2. Full-Process Data Automation: It automatically and continuously collects CP parameters (such as potential, corrosion rate) along the pipeline, with data upload delay ≤10 seconds. The data is directly accessed to intelligent algorithms to optimize control strategies, without manual recording and entry, and the data error rate is reduced to less than 0.1%.

3. Adaptive Stray Current Management: It independently identifies and diagnoses stray current interference types (such as DC, AC interference), and dynamically adjusts power supply output according to interference intensity. It can still maintain stable anticorrosion effect in complex interference environments, and the response speed is 5 times faster than traditional manual detection.

4. Intelligent Monitoring of Drainage Facilities: It automatically collects data such as drainage flow, CP parameters before and after drainage, and drainage bed potential of drainage facilities, with a monitoring frequency of 1 time/hour, replacing traditional manual regular inspection (1 time/week). The fault early warning accuracy reaches 95%, reducing the risk of equipment damage.

5. Tamper-Proof Data Acquisition: Using a dedicated Data Logger, test data is uploaded in real time and cannot be tampered with. The original data directly supports the optimization of control strategies, with a data credibility of 100%, meeting industry compliance requirements.

  8. Core Hardware: Intelligent Potential Acquisition Device, Corrosion Rate Monitor, Intelligent Drainage Device, Intelligent Cathodic Protection Power Supply

1. Anticorrosion for Long-Distance Oil & Gas Pipelines: For cross-regional long-distance oil and gas transmission pipelines (such as West-East Gas Pipeline), it provides full-mileage intelligent cathodic protection control, monitors pipeline corrosion status in real time, dynamically adjusts power supply parameters, ensures 100% anticorrosion coverage of pipelines, and extends pipeline service life to more than 20 years.

2. Anticorrosion for Regional Compressor Stations: Adapted to oil and gas regional compressor stations (such as Sidaoban Compressor Station in Tarim), it integrates data of cathodic protection equipment in the station, realizes remote control and abnormal alarm of station equipment, reduces the number of on-site operation and maintenance personnel, and lowers operation and maintenance costs by 30%.

3. Pipeline Protection in Stray Current Interference Areas: For pipelines in areas with dense stray currents such as industrial areas and railway lines, it uses adaptive interference management technology to offset the impact of stray currents in real time, maintain stable cathodic protection potential, and avoid accelerated local corrosion of pipelines.

4. Full-Lifecycle Management of Anticorrosion Equipment: Through equipment ledger maintenance, fault statistics, and historical data comparison, it provides data support for the maintenance and replacement of anticorrosion equipment (such as intelligent drainage devices, power supplies), reduces unplanned equipment downtime, and improves equipment utilization to more than 95%.
