step three, when the temperature inside the greenhouse body (1) is high and the illumination intensity outside the greenhouse body (1) is high, the temperature and humidity sensor (12) and the illumination intensity sensor (13) simultaneously transmit information to the programmable PLC (11), the programmable PLC (11) simultaneously controls the first servo motor (16), the second servo motor (17) and the third servo motor (56) to work, the heat preservation curtain (5) is pulled open through the first servo motor (16), meanwhile, the output shaft of the third servo motor (56) drives the rotating shaft (55) to rotate through the self-locking reducer, the sunshade net (57) is released, under the action force of the counterweight pressing bar (58), the surface of one end of the sunshade net (57) is attached to the surface of the fixed cross beam (102), and the sunshade net (57) is released through the first servo motor (16) and the pulling open of the heat preservation curtain (5) and the third servo motor (56), heat dissipation and sunshade are carried out on the interior of the greenhouse body (1);
step four, when the heat insulation curtain (5) needs to be covered again after the heat dissipation of the internal temperature of the greenhouse body (1), the PLC (11) can be programmed to send out an electric signal, simultaneously controls the first servo motor (16), the second servo motor (17) and the third servo motor (56) to work, the third servo motor (56) drives the rotating shaft (55) to rotate, the sunshade net (57) is rolled, the first servo motor (16) rotates reversely to drive the first rolling roller (14) to rotate reversely to release the first steel wire rope (8), the output shaft of the second servo motor (17) drives the second rolling roller (15) to rotate through the self-locking speed reducer, the second rolling roller (15) rolls the second steel wire rope (9), the second steel wire rope (9) drives the pulling cross rod (6) to slide in the stroke groove (3) to drive the heat-preservation curtain (5) to be unfolded, and heat preservation is carried out on the greenhouse body (1).
