Description
Technical field
The fire locating method based on infrared thermal imaging and laser guidance technique that the present invention relates to a kind of belongs to fire-fighting neck
Domain.
Background technique
Infrared thermal imaging uses the infrared ray specific band signal of photoelectric technology detection object heat radiation, which is converted
At the image and figure differentiated for human vision, and temperature value can be further calculated out.Infrared thermal imaging technique makes the mankind
Dysopia is surmounted, thus one can see that the temperature distribution state of body surface.
Infrared thermal imaging technique wide range of applications, and have in terms of detecting forest fire very high using valence
Value.Such as in the forest of large area, fire is often to be caused by unconspicuous hidden fire.This is the root of destructive forest fire,
With existing commonsense method, it is difficult to find this recessive fire symptom of a trend.However gone on patrol with aircraft, using infrared thermal imager, then
It can fast and effeciently find these hidden fire, fire is eliminated initial.Forestry in Canada institute begun to early in 1975 into
Row forest fire protection test, checks the not yet potential fire source in ignition ground from aircraft, and Canadian Forest research center utilizes helicopter
Using AGA750 Portable thermal imager, 15 hidden fire are found in a fire season.Spontaneous combustion often occurs for cereal silo
Phenomenon, often the time is long, the oncoming force is violent for this dieseling, loss is big.General using its silo of thermometer measure temperature at present
Variation is taken precautions against.Place and the range that these fire can be accurately determined using thermal imaging system are accomplished early to know early prevention, early be flutterred
It goes out.Convenient and simple using thermal imaging system, speed is fast, puts out in time.
But application of the infrared thermal imaging technique in fire water monitor fire locating has not been reported.
It is combined currently, fire water monitor fire locating generallys use red single-point type, ultraviolet probe or the outer combined probe of purple
Narrow slit technology is positioned, and cost is relatively low for this technology infrared probe, but long, the low efficiency that is scanned the time to environment space,
Position error is big, for example, one kind disclosed in Chinese patent 201210094849 automatically tracks positioning jet stream extinguishing device, China is specially
A kind of infrared guidance fire water monitor disclosed in benefit 201310734137.5.Jin Wei invent a kind of fire monitor of CN101745193A and its
The quickly method of positioning fire source.White vase invention CN201210094849 automatically tracks positioning jet stream extinguishing device.
What Chinese patent 201010243423 was said is to carry out scanning between determining entirely using a single-point type pyroelectric sensor surveying
Temperature, the temperature for comparing the total space compare data and return to maximum temperature point, realize positioning.Its sensor used is released for single-point type heat
Electric transducer, it is different from the infrared thermal imaging sensor that the present invention uses, dynamic tracing can not achieve to maximum temperature point.
Summary of the invention
It is a kind of based on infrared thermal imaging and laser guidance the invention aims to provide for the problems of the prior art
The fire locating method of technology.
In order to achieve the above object, the technical scheme is that a kind of be based on infrared thermal imaging and laser guidance technique
Fire locating method, which comprises the following steps:
1) pre-warning signal is received；
2) starting motor carries out infrared thermal imaging scanning, if going to step 3) without fire signal, if there is fire signal to turn
To step 4)；
3) it resets, waits next pre-warning signal；
4) driving motor compensates, so that infrared thermal imaging maximum temperature point is placed in the middle, then starts laser beam to highest
Temperature spot and its surrounding carry out positioning scanning, and after laser beam is radiated on fire source point, the laser beam being connected to according to receiver is anti-
Feedback signal carries out realization precise positioning.
Further, scanning process in step 2 are as follows:
A) start motor vertical small change point, stop；
B) start and lift 1 ° ~ 50 ° on motor vertical, stop；
C) starting horizontal motor is rotated to limit, is stopped；
D) start and lift 50 ° ~ 90 ° on motor vertical, stop；
E) starting horizontal motor is reversely rotated to limit, is stopped；
Scanning is completed after above step 2 ~ 4 weeks rotate horizontally.
Further, when infrared thermal imaging all standing scans, if maximum temperature point meets Fire Conditions, to there is fire letter
Number, it is otherwise no fire signal.
Further, the pre-warning signal comes from itself ultraviolet early warning or fire automatic alarm system, image-type fire
The outer links signals such as smoke detector, line style light beam smoke detector and artificial Fire Alarm Button.
Compared with prior art, the present invention carries out fire locating to fire water monitor using infrared thermal imaging technique, due to red
Outer thermal imaging is scanned in a manner of the battle array of face, and location efficiency is high, and speed is fast, can be with by laser guidance technique
So that improving positioning accuracy to the precise positioning of fire source point.
Detailed description of the invention
Fig. 1 is logic diagram of the invention.
Specific embodiment
The present invention will be further described below in conjunction with the embodiments.
