Obtain the expression formula of instantaneous intensity of illumination of each folding face on the indoor perspective plane of the temperature；
The intensity of illumination expression formula is subjected to Simpson's integral within a preset period of time, obtains each folding face described
Intensity of illumination on the indoor perspective plane of temperature.
Wherein, the plane given for one, its light transmittance is identical everywhere on given time, entire plane, and curved surface
It is quite different, since solar incident angle of the lighting surface on each point in greenhouse span direction is different, so the sun spoke on each point
It is also different to penetrate transmitance.Therefore, for ease of calculation, lighting surface is divided into many small folding faces.The number of small folding face number depends on
In the requirement to computational accuracy, theoretically, when folding face number tends to infinity, small folding face approaches curved surface, such as Fig. 2 completely

Wherein, (xi,yi) center location that indicates small round surface, on the perpendicular bisector of A, B two o'clock line, yi≤0。
The X axis coordinate of the every small curve of the model must satisfy the horizontal distance (L-L') in greenhouse daylighting face two-end-point
In range, Z axis coordinate is between the AB inclined-plane equation φ (x) formed and the high H of ridge, function monotone decreasing and to recessed feature,
I.e. shown in formula (7):
Step 3, the determination method of sunlight greenhouse curtain rolling aperture
Based on the mathematical model for the heliogreenhouse lighting surface established in step 2, following point is done to sunlight greenhouse curtain rolling aperture
Analysis, in Fig. 7:
