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.
Dá bhrí sin, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Tech Co., Teo. 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. Cruinneas tomhais teocht ard agus freagra tapa.
Is é réiteach teocht an óstaigh tomhais teochta 0.1 ℃, agus is é an cruinneas tomhais teochta ± 1 ℃. The temperature detection time for each channel is about 5 soicind.
2. Monatóireacht ar líne fíor-ama.
Monitor the temperature of the entire tunnel continuously for 7 × 24 uair an chloig, 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, is féidir rannóga tomhais teochta éagsúla a dheighilt agus a bhainistiú de réir riachtanais an chustaiméara. Go ginearálta, every 100M optical cable is set as a partition. Socraigh paraiméadair aláraim éagsúla do gach deighilt, mar rabhadh teochta, rabhadh ardú teochta, aláram teochta, agus aláraim ardú teochta, chun idirdhealú cruinn a dhéanamh idir tinte fíor agus bréagacha, and eliminate false alarms and omissions.
5. Complete self diagnostic function.
Sa chóras seo, agus teocht gach teocht a thomhas cábla optúil á bhrath, is féidir leis freisin stádas oibre gach cábla optúil a thomhas teocht a bhrath i bhfíor-am, amhail caillteanais bhreise de bharr damáiste cábla nó lúbthachta, agus suíomh an damáiste nó an lúbthachta a aimsiú go cruinn. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
