Description
Technical field
The present invention relates to a kind of fire alarm safety-protection system based on ultraviolet and image detecting technique and method.
Background technology
Along with City Building develops towards the direction of high stratification, densification, the generation of fire is more frequent, loss
The most increasing, the importance of preventing and treating fire is the most obvious.
Fire detector, as the core component of fire alarm system, about experienced by from heat detector → smoke detection
The development course of device → gas-sensitive detector → sensitive detector → video detector.
Traditional sense cigarette, temperature-sensitive, gas-sensitive detector, the smog produced by detection burning respectively, the change of ambient temperature
And harmful gas judges whether breaking out of fire.Have that the space suitability is limited, sensitivity is low, detection fire speed is slower
Shortcoming.
And sensitive detector, such as ultraviolet detector, the ultraviolet produced by detection flame combustion is radiated, and has sensitivity
The features such as high, detection flame speed is fast.But the most affected by environment, strong illumination or electro-welding arc all can be the most dry to its generation
Disturb, thus rate of false alarm is higher.
Video detector is a kind of fire detector based on image processing techniques, utilizes and images first-class video dress
Put, catch video information, and then call image recognition algorithm, to determine whether that fire occurs.Its capacity of resisting disturbance is relatively strong, empty
Between the suitability strong.
Generally in public place, have several video detectors, the real-time image information of these detectors shooting, can be first
It is transferred on a monitoring computer, is then carried out flame identification by computer operation image recognizer.During detection,
Computer to process the data message of multiple Video Detection point simultaneously, needs huge operand, so calculating captain can be caused
Time high loaded process, computational burden is overweight.And do not have fire most of the time, so its operand Many times is all
Useless, waste substantial amounts of computer resource.
Summary of the invention
The present invention is to solve the problems referred to above, it is proposed that a kind of fire alarm security protection based on ultraviolet Yu image detecting technique
System and method, the present invention can overcome easily be disturbed present in existing fire detection technology, rate of false alarm is high, Computing
The problems such as overload.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of fire alarm safety-protection system based on ultraviolet Yu image detecting technique, including ultraviolet data analysis module, combines
Close and analyze module, display module, alarm module and monitoring camera, wherein:
Described ultraviolet data analysis module, receives the ultraviolet radiation data of the monitoring area of detection, to monitoring area
Safe condition carry out anticipation, it is determined whether have the ultraviolet band data that flame is held；
Described comprehensive analysis module, the view data and the ultraviolet data that receive the monitoring area of monitoring camera collection are divided
The analysis result of analysis module, when ultraviolet data analysis module is determined with the ultraviolet band data that flame is held, to view data
It is identified, is confirmed whether breaking out of fire, if it is confirmed that breaking out of fire, will determine that result is sent to display module and shows,
Alarm module is reported to the police simultaneously.
Described ultraviolet data analysis module is including power circuit, central processing element and ultraviolet detector testing circuit, purple
External detector testing circuit is connected with the ultraviolet detector being arranged on monitoring area, the ultraviolet band conversion first held by flame
Become the signal of telecommunication, then the signal of telecommunication is carried out operation amplifier, then carried out computational analysis by central processing element, thus realize the condition of a fire
One-level judges.
Described comprehensive analysis module connects display module, in order to the video pictures showing monitoring area directly perceived.
Described comprehensive analysis module connects alarm module, receives the alarm signal that described comprehensive analysis module sends, and
Convert the signal into sound and light alarm signal or telecommunication network alarm signal.
Described comprehensive analysis module, and is arranged on the monitoring camera communication of monitoring area, receives its image gathered
Data.
Method of work based on said system, comprises the following steps:
(1) monitoring area is carried out video monitoring and ultraviolet radiation detection；
(2) UV signal gathered is analyzed, identifies the first probability that the condition of a fire occurs, root according to the frequency of pulse
Whether there is fire alarm according to the first probability judgment monitoring region, if it is determined that there is fire alarm, then enter step (3), otherwise return step
Suddenly (1)；
(3) video image is analyzed, again judges the second of the whether breaking out of fire of described region according to image information
Probability, if the second probability is more than predetermined threshold value, then judged result is output as very, starts and reports to the police, otherwise returns step (1).
The invention have the benefit that
(1) together with ultraviolet detector is compound to by the fire alarm safety-protection system of the present invention with monitoring camera, normally
In the case of, monitoring camera only carries out common security monitoring work, when ultraviolet detector detects fire signal, starts figure
As recognizer, carry out fire two grades judgement.The system schema that the present invention provides, can undertake the security monitoring work of public place
Make, the detection early warning work of fire can be undertaken again, and high-definition on-site video can be provided when fire alarm occurs, it is achieved that fire alarm
System and the combination of video monitoring system；
(2) on method for recognizing fire disaster, first detect ultraviolet, when ultraviolet detection to flame, restart image recognition algorithm.
This two-stage fire detection mechanism, on the one hand, reduce the rate of false alarm of fire alarm, on the other hand, it is to avoid computer is always
The heavy-duty service that operation image recognizer causes, improves the problems such as power consumption is big, temperature is too high, service life is short, fall
The amount of calculation that low computer is useless, it is to avoid the waste of resource.
Accompanying drawing explanation
Fig. 1 is the system construction drawing of the present invention；
Fig. 2 is the workflow diagram of the present invention.
Detailed description of the invention:
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
