Monitoring of Electromechanical Equipment in Expressway Tunnel Based on Optical Fiber Temperature Sensing
The optical fiber temperature sensing technology is applied to the temperature monitoring of electromechanical equipment in highway tunnel,resulting in the technical advantage of safety and real-time.In order to solve the problem that the heat dissipation of the mechanical and electrical equipment in the tunnel may trigger the false alarm of the system and optimize the operating effect of the temper-ature monitoring system,the characteristics of the temperature field in the highway tunnel are ana-lyzed,and the signal analysis and abnormal event identification and judgment methods are designed pertinently.The results of several field simulated abnormal temperature rise tests and long-term oper-ation verification show that the optical fiber temperature sensing system can timely and effectively mo-nitor and locate the abnormal temperature rise and sudden fire of electromechanical equipment in the highway tunnel.
