[0035] The adjacent photovoltaic panels 3 are connected through the photovoltaic panel connecting ropes 2.

[0036] The control unit 25 is connected with the rotating motor 14, the front control stepping motor 12, the rear control stepping motor 13 and the angle auxiliary adjustment module 15, the number of the angle auxiliary adjustment module 15 is four, one first angle adjustment transmission rope 4 and one second angle adjustment transmission rope correspond to one angle auxiliary adjustment module 15 respectively.

[0037] The angle auxiliary adjustment module 15 is located on the topmost photovoltaic panel 3.

[0038] One end of the auxiliary fixing rod 22, one end of the first supporting rod and the first electromagnet unit 17 are connected with one side of the first fixed base, the first armature 16 is fixed on the other end of the first supporting rod, the first angle adjustment transmission rope 4 is located between the auxiliary fixing rod 22 and the first armature 16, one end of the transmission rod 18 is connected with the other side of the first fixed base, the other end of the transmission rod 18 is connected with the second armature 20 through the transmission connecting shaft 19, the second fixed base is connected with one end of the second supporting rod and the second electromagnet unit 21, the other end of the second supporting rod is connected with the second armature 20, and the control unit 25 is connected with the first electromagnet unit 17 and the second electromagnet unit 21.

[0039] The output end of each photovoltaic panel 3 is connected with the electric energy collection module, the output end of the electric energy collection module is provided with the voltage and current detection module 24 for detecting the voltage and current signals at the output end of the electric energy collection module.

[0040] The working process of the application is as follows:

[0041] When the system needs to retract the photovoltaic curtain, due to the limiting effect of the first limiting block 5 and the second limiting block, the first angle adjusting transmission rope 4 and the second angle adjusting transmission rope cannot function, and each photovoltaic panel 3 is fixed through the photovoltaic panel connecting rope 2. In this state, since the terminal photovoltaic panel 3 is connected with the curtain retracting and releasing transmission rope 1, the curtain retracting and releasing transmission rope 1 is connected with the rotating motor 14, therefore, the curtain retracting and releasing transmission rope 1 is retracted through the rotating motor 14, the bottom photovoltaic panel 3 is first pulled up, and then each photovoltaic panel 3 is gradually pulled up in sequence, until all the photovoltaic panels 3 are retracted, and then the rotating motor 14 stops working. When the photovoltaic curtain needs to be unfolded, the rotating motor 14 is reversely rotated, and each photovoltaic panel 3 is sequentially lowered.

[0042] 2) When the photovoltaic curtain panel angle needs to be adjusted, for the first angle adjusting transmission rope 4, the first electromagnet unit 17 is controlled to be electrified, after being electrified, the first electromagnet unit 17 attracts the first armature 16 to move through magnetic force, and the first armature 16 and the auxiliary fixing rod 22 clamp the first angle adjusting transmission rope 4; after clamping the first angle adjusting transmission rope 4, the second electromagnet unit 21 is electrified, and the magnetic force attracts the second armature 20 to move and adhere to the second electromagnet unit 21; after the second armature 20 moves, the transmission effect causes the first angle adjusting transmission rope 4 and the transmission rod 18 to move, and then the first angle adjusting transmission rope 4 is rotated, since the terminal of the first angle adjusting transmission rope 4 is provided with the rotating ball 10 and the rotating track 11, the first angle adjusting transmission rope 4 is easily rotated after being subjected to the pulling force; after the first angle adjusting transmission rope 4 is rotated, the first limiting block 5 on the first angle adjusting transmission rope 4 rotates with the first angle adjusting transmission rope 4, and then the first angle adjusting transmission rope 4 is pulled by the front control stepping motor 12, and the first limiting block 5 is finally buckled at the bottom end of the photovoltaic panel 3; after buckling is completed, the front end and the rear end of the photovoltaic panel 3 can be controlled through the first angle adjusting transmission rope 4, at this time, the inclination angle of the photovoltaic panel 3 can be adjusted according to the control instruction and the power generation demand.

[0043] 3) The control unit 25 receives the control instruction, and controls the angle auxiliary adjusting module 15, the front control stepping motor 12, the rear control stepping motor 13 and the rotating motor 14 according to the control instruction and the detected voltage and current signals, so as to realize the photovoltaic curtain retracting and releasing and angle adjusting.

[0044] The application has two working modes, namely a system maximum power generation mode and a system external instruction control mode.

[0045] In the maximum power generation mode of the system, the control unit 25 detects the voltage and current signals at the output end of the electric energy collection module through the voltage and current detection module 24, and controls the angle auxiliary adjustment module 15, the front control stepping motor 12, the rear control stepping motor 13 and the rotating motor 14 to adjust the angle of each photovoltaic panel 3, so that the output power of the electric energy collection module is maximum, and the maximum power generation of the photovoltaic system is realized. The specific control process is as shown in Figure 6 .

[0046] In the external instruction control mode of the system, the user sends a control instruction to the control unit 25, and the control unit 25 adjusts the angle of the photovoltaic panel 3 through the angle auxiliary adjustment module 15, the front control stepping motor 12, the rear control stepping motor 13 and the rotating motor 14 according to the control instruction to realize the external instruction control adjustment. Reference is made to Figure 7 .
