Isisombululo senkqubo yokulinganisa ubushushu befiber optic kwiitonela zendlela

The highway tunnel is a high-risk area for fires. Due to the tunnel being a closed and narrow space with high traffic volume and poor ventilation conditions, vehicle traffic accidents are prone to cause fires and spread quickly, posing a significant threat to the safety of vehicles, personnel, and equipment, resulting in huge casualties and property losses.

If the temperature inside the tunnel can be monitored in real time, an alarm can be given in a timely manner in case of a fire, and the highway management office can be notified to take effective measures to immediately implement traffic control, prevent vehicles from continuing to enter the tunnel, and evacuate vehicles that have entered or around the tunnel entrance in a timely manner. It can reduce the greater harm caused by fires and create space conditions and precious time for firefighters to extinguish them in a timely manner.

Ngoko ke, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&I-Tech Co., Ltd. monitors the internal temperature of the tunnel in real time and provides fire warning and alarm, which is crucial for tunnel fire monitoring.

 

Characteristics of fiber optic temperature control system for highways

1. Ukuchaneka komlinganiselo ophezulu wokushisa kunye nokuphendula ngokukhawuleza.

Isisombululo seqondo lokushisa lomkhosi wokulinganisa ubushushu 0.1 ℃, kunye nokuchaneka komlinganiselo wobushushu ngu ± 1 ℃. The temperature detection time for each channel is about 5 imizuzwana.

2. Ixesha lokwenene esweni online.

Monitor the temperature of the entire tunnel continuously for 7 × 24 iiyure, and regularly save temperature measurement data to provide auxiliary data for health monitoring of highway tunnels.

3. Distributed detection without monitoring blind spots.

Real time monitoring can be carried out at every point within the range of temperature measurement optical cables, eliminating blind spots in monitoring and theoretically avoiding the possibility of missed fire reports.

4. Flexible zoning alarm control.

Through the monitoring software of the upper computer, amacandelo ahlukeneyo omlinganiselo wobushushu anokwahlulwa kwaye alawulwe ngokweemfuno zabathengi. Ngokubanzi, every 100M optical cable is set as a partition. Cwangcisa iiparamitha zealam ezahlukeneyo kwisahlulelo ngasinye, njengesilumkiso sobushushu, isilumkiso sokunyuka kobushushu, alarm yobushushu, kunye ne-alam yokunyuka kobushushu, ukwahlula ngokuchanekileyo phakathi kwemililo yokwenyani kunye nobuxoki, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Kule nkqubo, ngelixa ubhaqa ubushushu bentambo yokulinganisa iqondo lobushushu ngalinye, Iyakwazi ukubona ubume bokusebenza kwentambo yokulinganisa iqondo lobushushu ngalinye ngexesha lokwenyani, njengelahleko eyongezelelweyo ebangelwa ngumonakalo wentambo okanye ukugoba, kwaye ubeke ngokuchanekileyo indawo yomonakalo okanye ukugoba. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.

Inzwa yobushushu bokukhanya kweFayibha, Inkqubo yokubeka iliso ekrelekrele, Kusasazwe umenzi ifayibha optic e China
