Fiber Optic Fire Monitoring System

分散型光ファイバー温度検知システム has accurate measurement, 安定したパフォーマンス, 強力な抗干渉能力, and can realize long-distance temperature detection. The video-type fire detector can know more intuitively and quickly the location of the fire, the scale of the fire, the speed of the fire and smoke spreading direction, the situation of the trapped people and other information, so that the monitoring personnel can react quickly to control the development of the fire in the best possible time, and to prevent false alarms caused by the external environment. The firefighting linkage system is to make emergency response to the fire quickly and implement the rescue of personnel, ventilation system and evacuation of traffic. If the video surveillance system is used to supplement the distributed fiber-optic temperature sensing system, and the firefighting linkage system is used for emergency response to tunnel fires, then this system can fully integrate the advantages of all three into a complete tunnel fire monitoring and early warning firefighting system.

According to the fire characteristics of a tunnel of a long highway, in order to realize the efficient control of fire in a long highway tunnel, the company independently researched and developed a set of tunnel 火災監視 and early warning fire fighting system.
The distributed fiber-optic temperature sensing system continuously measures the temperature along the distribution line, which can accurately determine the location of the fire point and the temperature of each store in the tunnel, avoiding the interference of electromagnetic waves; the video monitoring system, 光ファイバーセンサーからの警報信号受信時, モニターを通じて火災現場の具体的な状況を素早く把握できる, 火災への迅速な対応が容易になります, 火災の発生を効果的に制御します, 消火と火災の救助を容易にします. 消火・救助システムも備えているので消火や救助にも便利です. 消防連携システムによりトンネル火災にも緊急対応可能.

試験用高速道路トンネルは 3 つのサブシステムで構成されています; 光ファイバー温度感知検出システム, 制御室間の情報共有, 現場の機器からのデータと情報の収集, 最終的には監視センターのコンピュータに送信されます, ビデオ監視システムと火災緊急対応システムの作動.

光ファイバー温度感知検知システムにより火災を検知した場合, 監視ビデオシステムは警報信号を素早く受信できます。, 火災の位置を画面に表示する, 確認後、ただちに消火連携システムを作動させ、消火と換気、トンネル内外への人の避難を実現します。
このトンネル火災監視・早期警戒消火システムの実現可能性を証明するために, そして同時に, 火災の進展パターンと火災の初期段階での煙の流れの速度を分析するための基盤を改善する, 点火テストをシミュレートしました. According to the “Fiber Optic Grating Temperature Sensing Fire Alarm System Design, Construction and Acceptance Specification”, the test tunnel was divided into four fire zones.

The test tunnel is divided into 4 fire zones, そして 1 fiber optic sensor is set up, 合計で 10 fiber optic sensors in each fire zone, forming 40 モニタリングポイント. One manual alarm button is installed at 50m intervals, and the alarm signal is transmitted by twisted pair cable. The fire source for the ignition test is a 0.68X0.68 m2 fire bowl, and the manual alarm signal and the temperature signal detected by the fiber optic are transmitted to the fire alarm control mainframe, and the OPC server implements the system. The ignition test shows that the system’s alarm position and temperature are accurate, the data are reliable, and the sensitivity is high. In the simulated ignition test of the long highway tunnel, the fastest alarm time of the system for a 0.5 m2 fire was 10 s. This test proved the feasibility of this tunnel fire monitoring and warning fire protection system.
