Abstract
The present invention relates to a quantitative detection method for the development trend of a fire and a fire behavior, which is mainly used for the fire-fighting field to carry out the quantitative detection on the fire behavior and can forecast the development trend of the fire. The present invention is characterized in that a detector installed on site carries out the infrared scan on a monitored space, digital processing is carried out on a detected infrared thermal source signal, and the processed data information is transmitted to a fire-fighting host. The host calculates and stores the obtainer data information in order to quantitatively detect the fire behavior. The present invention can carry out the equivalent analysis on the total power of a thermal source to obtain the change trend of the thermal source and can continue to monitor the thermal source to obtain the development trend of the fire after the fire occurs.
Description
Technical field
The present invention relates to a kind of development trend and intensity of a fire quantitative detecting method of fire, it is mainly used in the fire-fighting domain intensity of a fire to fire and carries out detection by quantitative, and the development trend of measurable fire.
Background technology
In the existing fire-fighting domain, the detection of fire has been only limited to or do not had, no matter be smoke detection or heat detection promptly, its result of detection all is whether fire takes place, can not carry out quantitative test, also just can't grasp the development trend of fire, and be that fire its effect of back takes place has just disappeared after alarm, can only play a generation of in time understanding fire, shorten the people the reaction time of fire, the effect of minimizing fire damage.At present, the manufacturer that segment detector is arranged is in order to solve this defective has added smokescope or temperature respectively separately in smoke detection or heat detection timing calculating, conveyer, make it the prediction of fire is played a role, yet, this mode still just only limits to smog, the temperature regime of detector loca, can not effectively grasp the actual conditions of whole space exploration, situation to hot source point can't be understood especially at all, and is just inoperative substantially after fire takes place equally.
Summary of the invention
Technical matters to be solved by this invention is to adopt a kind of development trend and intensity of a fire quantitative detecting method of fire, can work as component analysis to the general power of thermal source, know the variation tendency of thermal source, and after taking place, continues fire thermal source is monitored, know the development trend of the intensity of a fire, the defective that can not carry out quantitative test to fire to overcome prior art, can't understand the hot source point situation and after fire takes place, can't continue to provide useful data.
The present invention addresses the above problem the technical scheme that is adopted: by being installed in on-the-spot detector infrared scan is carried out in the space of being monitored, detected infrared heat source signal is carried out digitized processing, data message after will handling again is sent on the fire-fighting main frame, by main frame the data message that obtains is calculated and stores, with the intensity of a fire size of detection by quantitative fire.
The data message that main frame of the present invention obtained is meant the burning diameter and the temperature of thermal source, and main frame calculates above data, draws the added value of the burning area in real-time general power and unit interval.
The present invention works as component analysis according to the stored data of main frame with the real-time general power that calculates and the added value of the burning area in the unit interval, to judge the development trend of fire.
The present invention compared with prior art has the following advantages and effect: can work as component analysis to the general power of thermal source, know the variation tendency of thermal source, and continue thermal source is monitored the development trend of knowing fire after fire takes place.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the embodiments of the invention synoptic diagram.
Embodiment
Referring to Fig. 1-Fig. 2, the scanister 2 of main detector 3 of the present invention ceaselessly active carries out infrared scan in the space towards periphery, then with detected infrared heat source signal through digital processing element 4DSP chip, after carrying out preliminary digitized processing, result is sent on the fire-fighting main frame 6, carry out realtime power computational analysis and storage by main frame 6, main frame 6 forms the trend analysis of infrared heat source according to the data that store, and and the real-time general power calculated cooperate and judge whether to cause disaster.Wherein in real time general power is caused disaster for judgement and is had the index effect, because could constitute fire truly when having only general power when thermal source to reach certain equivalent, otherwise some are just being used fire always and will cause wrong report.And when fire took place, its trend analysis to thermal source had just become the analysis to fire development trend, and this analysis result has directive function to the route of how correctly to work out next step.
As shown in Figure 1,1 is thermal source, and 3 is main detector, and 2 is the scanister in the main detector, and 4 is the digital processing element dsp chip in the main detector.Scanister 2 sends thermal source 1 raw information that scans to digital processing element 4, after digital processing element 4 carries out digitized processing with these information, send result to fire-fighting main frame 6 by communication line 5, fire-fighting main frame 6 carries out the realtime power computational analysis according to these data and stores then, and fire-fighting main frame 6 forms the development trend of infrared heat source according to the data that store, analyze and and the real-time general power calculated cooperate and judge whether to cause disaster.
As shown in Figure 2, in the present embodiment, the big square frame 8 expression spaces of detecting, the left side, 3 expression main detectors, 7 expression burning things which may cause a fire disaster.Main detector 3 ceaselessly carries out infrared scan, and after its inner digital processing element dsp chip of burning things which may cause a fire disaster 7 information vias that scans carried out digitized processing, be sent on the fire-fighting main frame 6 via communication line 5, fire-fighting main frame 6 carries out the realtime power computational analysis according to these data and stores then, and form the trend analysis of infrared heat source according to the data that store, and and the real-time general power calculated cooperate and judge whether to cause disaster.
