Abstract: Monitoring measurement serves as an important technical means to ensure the safety construction of urban rail transit projects and the timeliness of the monitoring data appears to be particularly important. Based on the bluetooth wireless communication, mobile communication, database and other information means, according to the specific features of urban rail transit monitoring, a set of information management system suitable for urban rail transit monitoring was developed. This system implemented the full coverage of the monitoring operation processes and formed the closed loop of "acquisition-operation-processing-analyzing-warning-alarm-eliminating", ensured the truthfulness and timeliness of the monitoring data, actively promoted the traceability management and paperless monitoring of projects. Through the promotion and application of this information management system in the Kunming Rail Transit Line 4, it showed that the application of this system improved the monitoring level, reduced the monitoring cost, and also regulated the operation behaviors of monitoring units, which ensured that the monitoring data can more effectively guide the construction.
