Tunnel fire hazard endangers maximum Road Tunnel Safety accident, not only can cause the traffic jam in tunnel but also may produce heavy losses.How fast and accurately detection of fires is the key controlling rapidly the condition of a fire and implement to rescue and reduce loss to personnel.Because traditional fire detection technology (temperature-sensitive, sense cigarette, infrared and temperature sensing optical fiber etc.) is subject to the impact of tunnel complex environment, be difficult to realize fire detect in real time and also pre-warning time delayed, Detection Techniques current are in addition difficult to ensure to form comprehensive safety monitoring system.Along with the development of digital image processing techniques, for this difficult problem provides effective solution.Image-type fire detection technology arises at the historic moment, and it has larger advantage in system response time, antijamming capability, intelligent water equality.Herein by the particular surroundings of integrating tunnel, carry out the Study and appliance of the Tunnel Fire detection technique based on video.This technology accurately can detect fire in real time at Initial Stage of Fire, avoids the further expansion of fire, thus reduces casualties and property loss to greatest extent.Meanwhile, this technology can utilize the image capture device of tunnel video monitoring system, can simplify working procedure at the tunnel construction initial stage, and by video monitoring, event detection and fire alarm concentrate on same video platform; Can reduce the configuration of tunnel fire hazard checkout facility in the scrap build phase to a certain extent, save cost, avoid overlapping investment, there is certain economic benefit.
Utility model content
For the present situation of current Tunnel Fire warning system, the utility model provides a kind of tunnel image fire alarm system that can carry out image acquisition analysis in real time, can alarm cycle be reduced, can also monitor and event detection by integrating tunnel simultaneously, reduce working procedure.
For achieving the above object, the technical solution of the utility model is:
Tunnel video fire hazard warning system, it comprises: system is made up of parts such as real-time high-definition video collection, image fire alarm host machine, event detection main frame, remote interlocking monitoring host computer and system softwares.A configurable multiple video camera of alarm host machine, detects whole tunnel.Remote interlocking refers to by computer network, and accessible tunnel monitoring system, and alarm, to dispose fire in time.
As preferred version of the present utility model, described high definition video collecting equipment, adopt high-definition camera, can install in protective cover, there is dust-proof, moistureproof, corrosion proof function, to environmental factor adaptable (dust, humidity, temperature, general corrosion gas or explosion-proof place etc.), can be used for the places such as the tunnel of bad environments.
As preferred version of the present utility model, described image fire alarm host machine, employing can the alarm host machine of simultaneously detection of fires and smog, its response average velocity will faster than the current conventional detector used. and usually, detection system just can carry out probe response at the smog of ascension and the flame that just produced for what reach market height 3%.In most cases detector can make response to smog in 20sec, the fastest only needs a few second, to response time of flame within 10 seconds.
As preferred version of the present utility model, described event detection main frame, adopt industrial control computer processing host hardware configuration all to select technical grade computer equipment, have traffic incidents detection warning function, DETECTION OF TRAFFIC PARAMETERS warning function, system autodiagnosis warning function, recording function and system management function.
As preferred version of the present utility model, described remote interlocking monitoring host computer, adopt the monitoring management platform of the function such as fusion, remote monitoring, Remote is online, system manages, calamity emergency commander with data message and video, RS485 can be passed through, or network docks with tunnel monitoring system.
As preferred version of the present utility model, described system software, comprises the functional module such as system initialization (comprising the setting etc. of running parameter), surveyed area division, automatically detection, event detection, data management, automatic alarm, remote transmission.
A little of the present utility model:
The early stage warning alert of smog and fire, can real-time analysis image scene, makes a response fast for smog and flame.Very strong antijamming capability, has environment self-adaption function, carries out self study to the event confirming as false alarm, and the warning of righting the wrong.Sensing range is large, and maximum distance can reach hundreds of rice, and wide field angle, is applicable to the complex environments such as tunnel and uses.The position of fire can be provided accurately, for rescue work provides authentic communication.Also there is event detection function simultaneously, road traffic condition is detected, traffic incidents detection can be realized and report to the police.Can by fire alarm, event detection, video monitoring function integrates, and shortens working procedure in early stage, reduces later maintenance expense.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is system construction drawing of the present utility model.
1. high-definition cameras, 2. optical fiber transmission module, 3. video switch in figure, 4. image fire alarm host machine, 5. event detection main frame, 6. video monitoring main frame, 7. remote interlocking monitoring host computer, 8. tunnel monitoring platform, 9. database.
Embodiment
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.But this should be interpreted as that the scope of the above-mentioned theme of the utility model is only limitted to following embodiment, all technology realized based on summary of the invention of the present utility model all belong to scope of the present utility model.
As shown in Figure 1, system architecture of the present utility model is described, the utility model tunnel video fire hazard warning system primarily of high-definition camera 1, optical fiber transmission module 2, video switch 3, image fire alarm host machine 4, event detection main frame 5, video monitoring main frame 6, remote interlocking monitoring host computer 7, tunnel monitoring platform 8, database 9 forms.
Wherein high-definition camera 1 is installed with in tunnel, for the video acquisition of complex environment.Then video data is transferred to image fire alarm host machine 4 respectively by optical fiber transmission module 2 and video switch 3, event detection main frame 5 and video monitoring main frame 6.Warning message, by the identification to video, is transferred to tunnel monitoring platform 8 by remote interlocking monitoring host computer 7 by image alarm main frame 4.Event detection main frame 5, by the identification to video, is transferred to tunnel monitoring platform 8 by traffic event information by remote interlocking monitoring host computer 7.Transmission of video is used for monitoring to tunnel monitoring platform 8 by video monitoring main frame 6.Warning message, traffic event information and video image are supplied to monitor staff by tunnel monitoring platform 8, and send the prompting of chimes of doom light.Warning message, traffic event information and video image are kept in database 9 in order to consulting simultaneously.
Because tunnel environment is complicated, high-definition camera 1 can be positioned in protective cover, and according to tunnel feature position, and air line distance can 110 meters one, and turning is encrypted according to angle in good time.Image fire alarm host machine 4 can analyze the image of multiple stage high-definition camera 1, but to answer a main frame correspondence to be no more than 24 video cameras be good in order to the fire alarm corresponding time.Traffic incidents detection main frame 5 also may correspond to multiple stage high-definition camera 1, but in order to the accuracy of event analysis, it is good that a main frame correspondence is no more than 8 video cameras.Database 9 is ensure that the completing property of data should do redundancy.
