Tunnel is an important infrastructure in railway transportation,and tunnel protective door is an important safety protection equipment in tunnel.Currently,the daily inspection of tunnel protective doors is still carried out by inspection personnel,and the work efficiency is low.In this paper,according to the characteristics of railway tunnel protective doors,a monitoring system based on cloud,edge end and collection end was studied and constructed,which is used to provide the functions of state monitoring and fault alarm about tunnel protective doors.The system analyzes and processes data through SLS,Prometheus,Grafana and other technologies,and detects and alarms related faults.The implementation of this system verifies the practicability and feasibility of the architecture integrating cloud,edge port and collection port in the monitoring of tunnel protective doors.
