[0032] An adjustable assembled greenhouse, as Figure 1 and 2 shown, includes two groups of side frames 1 and a ceiling 2 fixedly connected to the top surfaces of the two groups of side frames 1. A plurality of windows are provided on the side frames 1, and a windproof glass 3 is fixedly connected inside the windows. A light-shielding plate 4 located outside the windproof glass 3 is rotatably connected inside the windows. A first driving motor 11 and a second driving motor 13 are respectively fixedly connected to the two side frames 1. Wire rollers are fixedly connected to the output shafts of the first driving motor 11 and the second driving motor 13. A connecting rope 5 is wound around the wire rollers. One end of the connecting rope 5 away from the wire roller passes through the windproof glass 3 and is fixedly connected to one end of the light-shielding plate 4 away from its rotation connection.

[0033] As Figure 3 shown, it also includes a light control circuit. The light control circuit is coupled to the first driving motor 11 and the second driving motor 13. The light control circuit controls the opening degree of the light-shielding plate 4 according to the ambient light intensity inside the greenhouse. The light control circuit includes a light intensity sensor 6, a voltage comparison circuit 7, a controller 8, a first motor driving circuit 10, a second motor driving circuit 12, and a clock circuit 9. The voltage comparison circuit 7 includes a voltage comparator. The controller 8 includes an STM32F103RCT6 embedded microcontroller. The first motor driving circuit 10 and the second motor driving circuit 12 include TB67S109AFTG motor driving chips.

[0034] The light intensity sensor 6 is arranged on the bottom surface of the ceiling 2. The light intensity sensor 6 collects the ambient light intensity in the greenhouse and feeds back a light intensity signal. The input end of the voltage comparison circuit 7 is coupled to the output end of the light intensity sensor 6. The voltage comparison circuit 7 outputs a comparison signal in response to the light intensity signal being less than the light intensity reference signal. The input end of the controller 8 is coupled to the output end of the voltage comparison circuit 7. The controller 8 outputs a first control signal in response to the comparison signal. The input end of the first motor drive circuit 10 is coupled to the output end of the controller 8. The output end of the first motor drive circuit 10 is coupled to the input end of the first drive motor 11. The first motor drive circuit 10 controls the forward and reverse rotation, start and stop of the first drive motor 11 in response to the first control signal. The input end of the second motor drive circuit 12 is coupled to the output end of the controller 8.

The first motor drive circuit 10 and the second motor drive circuit 12 control the forward and reverse rotation, start and stop of the first drive motor 11 in response to the second control signal.

[0035] When the utility model is actually working, the light intensity sensor 6 detects the ambient light intensity in the greenhouse and feeds back a light intensity signal to the voltage comparison circuit 7. The voltage comparison circuit 7 outputs a comparison signal in response to the light intensity signal being less than the light intensity reference signal. After the comparison signal is given to the controller 8, the controller 8 outputs a first control signal to the first motor drive circuit 10 and the second motor drive circuit 12. The first motor drive circuit 10 and the second motor drive circuit 12 can control the first drive motor 11 and the second drive motor 13 to work, so that the wire roller rotates accordingly. When the wire roller rotates, it can unwind or wind up the connecting rope 5, so that the available length of the connecting rope 5 changes. With the cooperation of the self-weight of the light-shielding plate 4, the light-shielding plate 4 can be deflected to adjust its opening degree, so that the external light can enter the greenhouse through the wind-proof glass 3. The setting of the clock circuit 9 can input a clock signal to the controller 8 and make the controller 8 output a second control signal under normal circumstances. The first motor drive circuit 10 and the second motor drive circuit 12 control the forward and reverse rotation, start and stop of the first drive motor 11 in response to the second control signal, so that the light-shielding plate 4 can be adjusted for opening and closing at a fixed time throughout the day.

For those skilled in the art, various modifications and variations can be made to the present utility model.
