Abstract
The invention relates to a wind speed/direction adapting system in an automatic-tracking fire extinguishing system, which is characterized in that a crosswind sensor installed on an automatic-tracking fire extinguishing device is utilized; the automatic-tracking fire extinguishing device acquires a real-time wind direction value, measured by the crosswind sensor, by a data line; a control system of a homing fire monitor device carries out real-time adjustment on a pitch angle and a horizontal intersection angle of a fire monitor by using a mathematical model in control software according to wind speed and direction values; and the homing fire monitor device controls jetting points of the fire monitor not to deviate.
Description
Technical field
The present invention relates to is a kind ofly having under the wind effect from the motion tracking fire extinguishing system, adjusts automatically from the motion tracking fire extinguishing system jet horizontal angle and the angle of pitch to adapt to the variation of wind speed and direction, thereby the spray site of system is not changed.
Background technology
At present, be a kind ofly can find to locate burning things which may cause a fire disaster automatically from the motion tracking fire extinguishing system, the automatic fire extinguisher with burning things which may cause a fire disaster puts out only is adapted at using under the calm environment from the motion tracking fire extinguishing system, and spray site can squint under the influence that wind environment is arranged.
Summary of the invention
The present invention can eliminate wind environment to the error from motion tracking fire extinguishing system spray site.
The technical solution adopted for the present invention to solve the technical problems is:
On device, crosswind sensor is installed;
In the motion tracking fire extinguishing system, gather the real-time wind direction and wind velocity value that crosswind sensor records through data wire;
According to the wind direction and wind velocity value, utilize the Mathematical Modeling in the control software that the angle of pitch and the level angle of fire monitor are adjusted in real time from the control system of motion tracking fire extinguishing system;
Do not squint from motion tracking fire extinguishing system control spray site;
The specific embodiment
Beneficial effect of the present invention can be eliminated wind environment to the error from motion tracking fire extinguishing system spray site; To be installed in the guard plot from the motion tracking fire extinguishing system; Gather the real-time wind direction and wind velocity value that crosswind sensor records from the motion tracking fire extinguishing system through data wire; Crosswind sensor is moving with jet, records two the wind speed component values parallel with vertical with jet, utilizes the Mathematical Modeling in the control software that the angle of pitch, the level angle of jet are adjusted in real time; The angle of pitch changes the influence of offsetting the wind speed component parallel with jet, and the influence of the wind speed component vertical with jet is offset in the change of level angle, and the spray site from the motion tracking fire extinguishing system is not squinted.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a sketch map of the present invention.
Fig. 2 is a Mathematical Modeling sketch map of the present invention.
Fig. 3 is a Mathematical Modeling sketch map of the present invention.
1. from the motion tracking fire extinguishing system among the figure, 2. crosswind sensor, 3. spray site.
Among Fig. 1; To install on the ground from motion tracking fire extinguishing system level, and on device, crosswind sensor will be installed, the jet length of system is relevant at the initial velocity of spout with the jet elevation angle and extinguishing chemical; Flow velocity can be relevant with caliber at ducted flow from extinguishing chemical, under perfect condition:
V＝(πr
2D)/Q
V: flow velocity r: caliber Q: flow D: proportion
When under calm ideal situation, suppose that the jet elevation angle is α, spout initial velocity is set at flow velocity V, and the movement locus of extinguishing chemical is a parabola,
V1＝Vsinα V2＝Vcosα
Hm＝V12/2g t＝2V1/g L＝V2t
L＝(Vcosα)(2Vsinα/g) (1)
V: extinguishing chemical initial velocity
α: the jet elevation angle
Hm: jet is penetrated height
L: fire monitor range
T: flight time
Decide the spray site horizontal sextant angle utilizing jet to horizontally rotate, thereby obtain the spray site position.
Under the ideal situation that wind is being arranged, spraying track can change, and mainly influences range and level angle, and as shown in Figure 1, the Y axle is an injection direction, and is overlapping with the Y axle component Vfy of wind speed Vf, makes jet speed become V2+Vfy; The X axle component Vfx of wind speed Vf has become the horizontal-jet track simultaneously, and the injection drop point is squinted;
Solution is for making the jet horizontal direction to Vfx deflection in the other direction, and finally being V2 offsets at * axle component V2x and Vfx, both V2x=Vfx; At this moment the jet jet velocity component of Y axle is V2y+Vfy, change jet angle of pitch α according to formula (1) jet length L remained unchanged, from but the injection drop point of system is constant.
