Research on large capacity data acquisition and storage system based on metro monitoring

Abstract

Real time monitoring of subway tunnel can prevent major structural safety accidents, and it is of great significance to take measures to maintain the structure and prolong the service life of the structure. First, we introduce the framework of the metro monitoring system based on mobile terminal. According to the real-time data display needs, real-time data acquisition module using the application programming interface was developed. Second, the structure of hierarchical storage table was proposed, which can better solve the problem of the efficiency of huge data retrieval and storage, and it provides the feasible scheme for subway tunnel monitoring system.
