摘要
为了对公路隧道沿线进行实时温度监测,及时预警火灾发生,保证隧道的安全运营,利用光纤光栅测温技术进行隧道环境监测,同时为了提升测温系统自身的准确性和稳定性,提出利用时间序列预测技术,对各个监测位置长时间的温度变化规律进行统计分析,从而实现系统的自查和调整。实践证明,运用光纤光栅测温系统能够更加恰当地描述隧道空间的温度变化规律,从而提升公路隧道安全运营管理水平。
In order to monitor the real-time temperature along the highway tunnel,timely alarm the fire and ensure the safe operation of the tunnel,the fiber grating temperature measurement technology was used to monitor the environment of the tunnel.In order to improve the accuracy and stability of the temperature measurement system itself,the time series prediction technology was proposed to analyze the long-term temperature variation of each monitoring position.Thus the self-investigation and adjustment of the system can be realized.It has been proved that the use of fiber grating temperature measurement system can describe the temperature variation of tunnel space more accurately,thereby improving the operation safety and management of highway tunnels.
