Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 to 2 show an example structure figure of the present utility model, including: base and vertical bracing frame 2；?
Support 2 can stretch along short transverse；Support frame as described above 2 includes left and right support bar and horizontal rotating shaft 5, and left and right supporting bar top sets
Have position relatively, the most equal screw, horizontal rotating shaft 5 two ends are provided with the screw thread matched with screw, horizontal rotating shaft 5 with left,
Right support bar is spun by screw helicitic texture respectively；Horizontal rotating shaft 5 is provided with object stage, and object stage is fixed with photographic head 1,
This design can make object stage rotate around horizontal rotating shaft 5 place straight line, thus adjusts the lens direction of photographic head 1；Photographic head 1
Outer sheathed protective cover 3, protective cover 3 is transparency glass plate 4 towards the one side of photographic head 1 camera lens；Transparency glass plate 4 is swash plate, its
Height near photographic head one end is high further away from the height of photographic head one end.
Photographic head 1 is infrared camera, it is possible at shooting at night flue dust, can be placed in roof during shooting, Organization Chart such as Fig. 3
Shown in, sunlight impact shooting is avoided in placement of being exposed to the north.Bracing frame 2 material is rustless steel, Extensible, and flintiness is high, be difficult to by
Corrosion, firmly installs.Protective cover 3 is stainless steel material, it is possible to protection photographic head, it is to avoid photographic head is by sunlight, flue dust and rain
The infringement of the foreign objects such as water, extends photographic head service life.Left surface is designed to transparency glass plate 4, and transparency glass plate 4 is set
Being calculated as inclined-plane, the shooting angle making photographic head 1 is bigger.The outfan of photographic head 1 is connected with computer 7, the image that will collect

Use the above-mentioned flue dust image collecting device that tests the speed when estimating, by infrared camera in a certain time interval
It is continuously shot collection image information.Being illustrated in figure 5 this utility model measuring principle schematic diagram, its principle is: utilizes and asks random
The method of process cross-correlation function extreme value carrys out measuring speed, if stationary random process observing time being T, then and its cross-correlation function
Rxy(τ) as shown in formula (1):
When flue dust rises with speed V, the flue dust risen from throat is being separated by intervals t0Carry out twice
Shooting, chooses flue dust volume and concentration change image A and B of certain part, stochastic signal x (t) corresponding A image, stochastic signal y
(t) corresponding B image, i.e. y (t)=x (t-t0)；Flue dust B is at certain time t0The distance that A rises relatively is L.
The flue dust climb of shooting and concentration change image are transported to computer and carry out related operation, when processing image
Systemic concentration data base contrast with setting up, finally draws flue dust flow rate measurements, flue dust flow rate measurements V:
V=L/t0 (2)
The impact that correction wind speed brings, is illustrated in figure 6 shown in this utility model wind speed correction schematic diagram, according to orthogonal point
Solution, initial flue dust flow rate measurements is sum velocity V, then can get flue dust actual flow velocity V1=Vcos θ.
Flue dust discharge capacity obtains according to below equation: discharge capacity=flue dust actual flow velocity * throat sectional area * drain time, cigarette
Chimney mouth sectional area is learnt according to factory chimney practical situation.Finally flue dust actual flow velocity and discharge capacity are transported to display show.
If discharge capacity exceeds standard, alarm unit is reported to the police and notifies that relevant department's rectification processes.
