With the continuous development of the national pipeline network, the scales of system business and disaster data have increased significantly. A pipeline geological disaster monitoring and early warning system based on the microservice architecture is developed to prevent the occurrence of accidents that are vulnerable to geological disasters during long-distance pipeline transportation. The system adopts the mode of separated front-end and back-end development and has the characteristics of high concurrency, low coupling, high availability, and easy expansion. It integrates observation, reporting, research, risk assessment, and forecasting and early warning functions. At present, the system has been operating stably in national pipeline network branches for a long time, effectively settling disaster early warning, disaster handling, disaster information management, and other issues. The proposed system provides effective solutions for the long-distance transportation pipeline industry.
