In order to cope with the increasing demand for intelligent operation and maintenance of cable lines and lean management, carry out the research on the overall solution of the cable tunnel comprehensive status monitoring system, development of monitoring system based on microservices. By studying the microservice architecture and key component technologies, combined with business needs and expert experience to complete the construction of a system framework based on the Spring Cloud architecture.Based on the microservice architecture, the specific implementation process of the monitoring system was formulated, and the development of four microservices including comprehensive display, query statistics, operation management and system management was completed. Realize real-time monitoring of cable tunnels and cable lines. Through the pilot application of an engineering project, the advantages of the micro-service-based cable tunnel comprehensive status monitoring system were verified to meet the needs of intelligent operation and maintenance and lean management of cable lines.
