[Objective] To meet the development needs of railway electricity work monitoring services and address issues such as high coupling degree, lengthy deployment time, and high construction and operational costs in conventional signal monitoring system architectures, an architecture design scheme for a SCMS (signal centralized monitoring system) based on cloud computing technology is proposed. [Method] The architecture and network framework of conventional SCMS are introduced. The current application status and existing issues of the SCMS are analyzed. Three service forms and deployment methods provided by cloud computing technology are introduced. Combining the requirements of railway safety production and the nature of SCMS, the proposed SCMS is deployed and tested, and its evaluation indicators are analyzed. [Result & Conclusion] The proposed SCMS architecture is deployed using a private cloud, ensuring the security and controllability of data and assets. The system is designed using distributed architecture and cluster mode, enabling the use of automated scripts to read configuration information, distribute files, and operate processes, thus achieving the automated deployment of SCMS. Test results demonstrate that the architecture design scheme of SCMS based on cloud computing technology can optimize resource allocation and flexibly deploy the SCMS, exhibiting stable and reliable performance.
