2, revolving door running control software:
A, reference bearing adjustment program: for system provides reference bearing (being system's 0 degree).For avoiding because of instantaneous wind direction instability causes revolving door operation shake this program insertion time delay subroutine.
B, wind page or leaf deflection angle control program: (1) revolving door is being controlled in the driftage process automatically, according to the deflection angle of orientations of major sensor signal control wind page or leaf; (2) alert program: when the operation of wind page or leaf stopped deflection or logical miss fault, system alarm also started the shutdown BUF; (3) off-loading program; When wind speed during greater than the nominal operation wind speed, Industrial Control Computer starts the off-loading program, changes wind page or leaf driftage control angle, reduces the wind load of wind page or leaf, avoids the damage of high wind to equipment; (4) out of service if revolving door needs, for preventing inertia impact, should start the shutdown BUF earlier, manual shut-down is carried out in the back; (5) since air door by
quadrant to
quadrant or by
quadrant during to
quadrant transition; The angle of wind page or leaf normal and wind direction is answered corresponding rapid change, so establish wind page or leaf deflection accelerated procedure.
C, wind page or leaf zero clearing program: owing to adopt the driving execution element of the lower printed circuit motor of precision as the wind page or leaf, so establish the zero clearing program.Every tool air door rotates 2 π degree and promptly carries out wind page or leaf zero clearing program, and the wind page or leaf is driven playback, to eliminate the deflection accumulated error of wind page or leaf.
Control signal is taked the wireless radiofrequency transmission means.
3, the working principle of revolving door and technical parameter:
(1), the working principle of revolving door is shown in figure 12:
This equipment is a plurality of revolving door series combination.Each revolving door is made up of main shaft and the six tool air doors that are π/3 angles.Every tool air door carries six and possesses the also wind page or leaf of controlled synchronous deflection of dynamic driving.The motion state of revolving door is controlled by software program.
Setting revolving door and wind page or leaf rotation direction is the counterclockwise rotation direction of overlooking direction.Wind direction Φ d is 0 ° with geographic coordinate system D due east direction.System coordinate system (the reference bearing coordinate of software program) T is 0 ° with wind direction.Φ x is the angle of air door arm and wind direction, and Φ y is the angle of wind page or leaf normal and wind direction.When change of the wind, software program is set up system coordinate system T according to the wind direction transducing signal, for the reference bearing coordinate is set up in the systems soft ware operation.Adjust the initial operating angle of wind page or leaf simultaneously, form two arm wind page or leaf normal quadratures.In the revolving door rotary course, wind page or leaf deflection angle control program keeps wind page or leaf normal to follow the tracks of wind direction with orthogonal manner all the time according to the synchronous deflection wind of the rotation variable page or leaf of main shaft angle transducer.When air door one arm turns to system coordinates Φ x=0-а; When another arm of symmetry turns to Φ x=π-в; Wind page or leaf deflection accelerated procedure is accelerated the deflection speed of wind page or leaf, and in а and в angle, the wind page or leaf that the former normal of an arm is parallel with wind direction is transformed into vertical with wind direction; The wind page or leaf of another arm is transformed into and wind direction and wind direction parastate.Continue to keep wind page or leaf normal to follow the tracks of wind direction with orthogonal manner all the time.The transition angle that а and в change conversion for the wind page or leaf, its value is π/10.
(2), working principle and important technological parameters
For making the analytical calculation process simple and clear, do to simplify as follows:
A, do not consider the viscosity of air, ignore the Reynolds coefficient;
B, air door are regarded as the uniform thin plate of surface density;
C, wind page or leaf are when
quadrant, and blast density is even; When
quadrant, blast density is 0;
D, air resistance coefficient are 1;
E, disregard the friction negative work of motion.
Power:
1, the wind acting on the throttle? (Wind pages
quadrant)
According to bernoulli equation, blast density is:
Fm=1/2Cr ρ V
29.8=0.6125V
2(N) (formula 1-1)
Cr (air resistance coefficient)=1
ρ (air density)=0.125Kg/m
3
V (wind speed)=m/t
The blast of every tool air door
Fmax=FmS air door area S=H (air door height) R (air door radius) (formula 1-2);
2, throttle tangential force? (Throttle at
quadrant)
In the circular movement process; Air door is parallel with wind direction at the normal that
quadrant remains three tool air doors; The promotion that receives wind-force moves in a circle, and this Driving force is decomposed into tangential force and radial force on particle.The Driving force of tangential force circular movement wherein.
The function expression of every tool air door tangential force:
Fa=?Fmax·Sin(ωt＋Φa)Φa=0
Fb=?Fmax·Sin(ωt＋Φb)Φb=?π/3
Fb=FmaxSin (ω t+ Φ c) Φ c=2 π/3 (formula 1-3)
The functional picture of representation is shown in figure 13:
The fourier progression expanding method formula of tangential force function:
Fa=?2Fmax/π-4?Fmax/π[1/3·Cos(ωt+Φa)+?1/15·Cos(2ωt+Φa)
(3 ω t+ Φ are (4n a)+1/ for+1/35Cos
2-1) Cos (n ω t+ Φ is a)] (formula 1-4)
Fb=?2Fmax/π-4?Fmax/π[1/3·Cos(ωt+Φb)+?1/15·Cos(2ωt+Φb)
+ 1/35Cos (3 ω t+ Φ b)+1/ (4n
2-1) Cos (n ω t+ Φ b)] (formula 1-5)
Fc=?2Fmax/π-4?Fmax/π[1/3·Cos(ωt+Φc)+?1/15·Cos(2ωt+Φc)
+ 1/35Cos (3 ω t+ Φ c)+1/ (4n
2-1) Cos (n ω t+ Φ c)] (formula 1-6)
Can be known by above series expansion: tangential force can be decomposed into harmonic component and non-harmonic component.Because the effect of function perpendicularity in the harmonic component and collection wind assembly inertia, harmonic component is inoperative in air door moves in a circle process.The active force of circular movement is the non-harmonic component sum of three tool air door tangential forces.And the non-harmonic component of tangential force is a definite value under the constant situation of wind-force, wind direction, so the motion of air door is a uniform circular motion.
The active force of air door uniform circular motion:
Fd=6Fmax/ π (formula 1-7);
3, the speed of revolving door is changeed
Use above-mentioned analysis calculation method, can obtain:
The linear velocity at revolving door circular movement track edge;
Vx=2V/ π (formula 1-8)
Revolving door circular movement angular velocity
ω=Vx/R=2V/R π R (revolving door radius) (formula 1-9)
Tip-speed ratio λ=Vx/V=2/ π (formula 1-10)
Because the blast density profile is even, thus Fd point of action Ro is regarded as the R/2 place, so the air door turning radius does
Ro=Rs/2。Its linear velocity:
Vxo=Ro ω=V/ π (formula 1-11);
4, power
Wd=FdVxo=0.373V
3S10
-3(Kw) (formula 1-12)
Wd is the power of single tool revolving door, and complete machine power is:
W=nWd n (the polyphone quantity of unit air door) (formula 1-13);
(2) starting wind velocity
From the structure of this equipment, starting wind velocity depends primarily on the friction torque of complete machine and the starting torque of load.But transmission is rolling friction, and its moment can be ignored.The principal element that influence starts wind speed is the starting torque of load.So:
Gmax=Ro·n·Fd
Vmin=(Gmax π/1.84n H)
1/2/ R (m) (formula 1-14)
Vmin (starting wind velocity) Gmax (Nm of starting torque unit of load);
(3) maximum functional wind speed
The factor of the work wind speed that has the greatest impact is the mechanical strength of equipment.The design's maximum functional wind speed is:
Vmax=20 m/t (formula 1-15);
(4) power coefficient
The power coefficient of at present wind energy of this kind structure being equipped does not still have definition.Adopt the definition of the power coefficient of horizontal axis oar blade type to calculate the power coefficient of this kind structure, only with qualitative analysis at present.
C ≈ Wd (output power of single tool revolving door)/Wmax (acting on single tool revolving door wind energy power) ≈ 0.6.
