Fig. 8 to 16 are flowcharts of the operation method of the sunshine adjusting device of the invention. In operating the sunshine adjusting device according to the present invention, as shown in fig. 8, the wireless connection port 123 coupled to the control circuit 121 is initially required to pair the remote controller 600, so that the remote controller 600 can input an initial position setting instruction, a lower rail lower limit position setting instruction, an intermediate rail upper limit position setting instruction, a lower rail upper limit position setting instruction, a short press instruction or a long press instruction to the control circuit 121 through the wireless connection port 123. In the standby state 1 (step S1), when it is confirmed that the pairing key is pressed (step S2), it is determined whether the pressing time exceeds 3 seconds (step S3), and if the pressing time exceeds 3 seconds, the wireless spectrum pairing data is cleared (step S4), that is, the pairing data related to the bound remote controller is released last time. Then, if it is determined that the pairing command is received (step S5), performing wireless spectrum pairing (step S7), i.e., immediately binding the current remote controller 600, and entering the standby state 2 (step S8); if the pairing command is not received and the waiting time exceeds 2 seconds (step S6), the system returns to the standby state 1 (step S1). In the operation method of the present invention, the control circuit 121 of the present invention can be coupled to a maximum of 12 remote controllers 600, and if another remote controller 600 needs to be added, the control circuit 121 can perform wireless spectrum pairing with another remote controller 600 within the specific time (for example, 2 seconds) according to the instruction (which may be the same as the pairing instruction) of the added remote controller. Further, when the control circuit 121 receives the pairing clearing command, the control circuit 121 clears all data of the wireless spectrum pairing.

As shown in fig. 9, when the control circuit 121 determines that the initial position setting command is received after entering the standby state 2 (step S8) (step S9), the first driving module 20 and the second driving module 30 enter the initial position setting state (step S10). During the initial position setting state, the first driving module 20 configures the middle rail 50 clamped between the first and second shade curtains 100 and 200 to a first initial position spaced apart from the ground by a first initial height according to the short press command or the long press command. The second driving module 30 is configured to be fixed to the lower rail 60 at the bottom of the second shade curtain 200 to a second initial position spaced apart from the ground by a second initial height according to the short press command or the long press command. Further, when it is confirmed that the short press command has been received (step S11), the middle rail 50 or the lower rail 60 is stopped by only inching (moving) one step (which may be up or down) (step S12), and then the initial position setting is performed (step S13); if it is confirmed that the short press command is not received, it is then determined whether the long press command is received (step S14). When it is confirmed that the long press command is received, the middle rail 50 or the lower rail 60 is operated continuously in one direction (up or down is possible) (step S15) until the stop command is received (step S16), and then the initial position setting is performed (step S13). If the long press command is not received, then judging whether a forward/reverse switching command is received (step S17), if so, returning to the initial setting state (step S10); if not, then determining whether to wait for more than 2 seconds (step S18), if so, returning to standby state 2 (step S8); if not, the process proceeds to initial position setting (step S13). Finally, if it is determined that the initial position confirmation command has been received (step S19), the initial position setting state is ended and the system enters the standby state 3 (step S20). In the operation method of the present invention, the first initial position may be a position of the middle rail 50 when the first screen 100 is completely folded, and the second initial position may be a position of the lower rail 60 when both the first screen 100 and the second screen 200 are completely folded. Further, when the control circuit 121 receives the command to restore the initial setting, the first driving module 20 controls the middle rail 50 to move to the first initial position, and the second driving module 30 controls the lower rail 60 to move to the second initial position.

As shown in fig. 10, when the control circuit 121 determines that the lower limit position setting command is received after the initial position setting state is ended and the standby state 3 is entered (step S20) (step S21), the second drive module 30 enters the lower limit position setting state (step S22). During the above setting state, the second driving module 30 configures the lower rail 60 to a lower limit position of the lower rail according to the short press command or the long press command, the lower limit position of the lower rail being spaced from the ground by a first minimum height. Further, when it is confirmed that the short press command has been received (step S23), the down rail 60 is stopped by only one step of down inching (step S24), and then down rail down limit setting is performed (step S25); if it is confirmed that the short press command is not received, it is then determined whether the long press command is received (step S26). When it is confirmed that the long press command is received, the lower rail 60 is operated continuously in one direction (for example, downward) (step S27) until the stop command is received (step S28), and then the lower rail limit setting is set (step S25). If the long press command is not received, then judging whether a forward/reverse switching command is received (step S29), if so, returning to the lower rail lower limit position setting state (step S22); if not, then determining whether to wait for more than 2 seconds (step S30), if so, returning to standby state 3 (step S20); if not, the process proceeds to the lower limit setting (step S25). Finally, if it is determined that the lower limit position confirmation command has been received (step S31), the lower limit position setting state is ended and the state enters the standby state 4 (step S32).

As shown in fig. 11, when the control circuit 121 determines that the middle rail lower limit position setting command is received after the lower rail lower limit position setting state is ended and the standby state 4 is entered (step S32) (step S33), the first drive module 20 enters the middle rail lower limit position setting state (step S34). During the middle rail lower limit position setting state, the first driving module 20 configures the middle rail 50 to the middle rail lower limit position according to the short press command or the long press command, and the middle rail lower limit position is spaced from the ground by a second minimum height. Further, when it is confirmed that the short press command has been received (step S35), the middle rail 50 is stopped by only one step of inching down (step S36), and then the middle rail down limit setting is performed (step S37); if it is confirmed that the short press command is not received, it is then determined whether the long press command is received (step S38). If it is confirmed that the long press command has been received, the middle rail 50 is operated continuously in one direction (for example, downward) (step S39) until the stop command is received (step S40), and then the middle rail lower limit setting is set (step S37). If the long press command is not received, then judging whether a forward/reverse switching command is received (step S41), if so, returning to the middle rail lower limit position setting state (step S34); if not, then determining whether to wait for more than 2 seconds (step S42), if so, returning to standby state 4 (step S32); if not, the process proceeds to the middle-rail lower limit setting (step S37). Finally, if it is determined that the command for confirming the middle rail lower limit position has been received (step S43), the middle rail lower limit position setting state is ended and the state enters the standby state 5 (step S44).

In the operation method of the present invention, after the completion of the lower rail lower limit position setting state and the middle rail lower limit position setting state is confirmed, the lower rail 60 and the middle rail 50 may sequentially move in the same direction or in the opposite direction, and the lower rail 60 and the middle rail 50 may simultaneously move in the same direction or in the opposite direction. Further, the upper rail 70 may be fixed to an upper side of a door window of a building or a vehicle through a locking member 500 (as shown in fig. 2); after confirming the end of the lower rail lower limit position setting state and the middle rail lower limit position setting state, the lower rail 60 and the middle rail 50 enter the first state, the second state, the third state, the fourth state, the fifth state, the sixth state, the seventh state, or the eighth state. The first state sequentially performs the middle rail 50 down and the lower rail 60 down, the second state sequentially performs the middle rail 50 up and the lower rail 60 up, the third state sequentially performs the middle rail 50 down and the lower rail 60 up, the fourth state sequentially performs the middle rail 50 up and the lower rail 60 down, the fifth state simultaneously performs the middle rail 50 down and the lower rail 60 down, the sixth state simultaneously performs the middle rail 50 up and the lower rail 60 up, the seventh state simultaneously performs the middle rail 50 down and the lower rail 60 up, and the eighth state simultaneously performs the middle rail 50 up and the lower rail 60 down.

As shown in fig. 12, when the control circuit 121 determines that the middle rail upper limit position setting command is received after the middle rail lower limit position setting state is ended and the standby state 5 is entered (step S44) (step S45), the first drive module 20 enters the middle rail upper limit position setting state (step S46). During the middle rail upper limit position setting state, the first driving module 20 configures the middle rail 50 to a middle rail upper limit position according to the short press command or the long press command, the middle rail upper limit position being spaced from the ground by a first maximum height. Further, when it is confirmed that the short press command has been received (step S47), the middle rail 50 is stopped by only one step of upward inching (step S48), and then the middle rail upper limit setting is performed (step S49); if it is confirmed that the short press command is not received, it is then determined whether the long press command is received (step S50). If it is confirmed that the long press command has been received, the middle rail 50 is operated continuously in one direction (for example, upward) (step S51) until the stop command is received (step S52), and then the middle rail upper limit setting is performed (step S49). If the long press command is not received, then judging whether a forward/reverse switching command is received (step S53), if so, returning to the middle rail upper limit position setting state (step S46); if not, then determining whether to wait for more than 2 seconds (step S54), if so, returning to standby state 5 (step S44); if not, the process proceeds to the middle rail upper limit setting (step S49). Finally, if it is determined that the middle track upper limit position confirmation command has been received (step S55), the middle track upper limit position setting state is ended and the standby state 6 is entered (step S56).

As shown in fig. 13, when the control circuit 121 determines that the lower rail upper limit position setting command is received after the middle rail upper limit position setting state is ended and the standby state 6 is entered (step S56) (step S57), the second drive module 30 enters the lower rail upper limit position setting state (step S58). During the upper limit position setting state of the lower rail, the second driving module 30 configures the lower rail 60 to the upper limit position of the lower rail according to the short-press command or the long-press command, and the upper limit position of the lower rail is spaced from the ground by a second maximum height. Further, when it is confirmed that the short press command has been received (step S59), the lower rail 60 is stopped by only one step of inching (inch shifting) (step S60), and then the lower rail upper limit setting is made (step S61); if it is confirmed that the short press command is not received, it is then determined whether the long press command is received (step S62). When it is confirmed that the long press command has been received, the lower rail 60 is operated continuously in one direction (for example, upward) (step S63) until the stop command is received (step S64), and then the lower rail upper limit setting is set (step S61). If the long press command is not received, then judging whether a forward/reverse switching command is received (step S65), if so, returning to the lower rail upper limit position setting state (step S58); if not, then determining whether to wait for more than 2 seconds (step S66), if so, returning to standby state 6 (step S56); if not, the process proceeds to the lower rail upper limit setting (step S61). Finally, if it is determined that the down run upper limit position confirmation command has been received (step S67), the down run upper limit position setting state is ended and the state enters the standby state 7 (step S68).

As shown in fig. 14, when the down tracking upper limit position setting state is ended and the standby state 7 is entered (step S68), the control circuit 121 sequentially determines the following: whether an initial setting restoration instruction is received (step S69), whether an upper limit position resetting instruction is received (step S70), whether a lower limit position resetting instruction is received (step S71), whether an upper limit position resetting instruction is received (step S72), whether a lower limit position resetting instruction is received (step S73), whether a pairing instruction is received (step S74), and whether a new remote controller adding instruction is received (step S75). If the reset initial setting command is confirmed to be received, the system returns to the standby state 2 (step S8), if the reset lower rail upper limit position command is confirmed to be received, the system returns to the standby state 6 (step S56), if the reset lower rail lower limit position command is confirmed to be received, the system returns to the standby state 3 (step S20), if the reset middle rail upper limit position command is confirmed to be received, the system returns to the standby state 5 (step S44), if the reset middle rail lower limit position command is confirmed to be received, the system returns to the standby state 4 (step S32), if the pairing command is confirmed to be received, the system returns to the standby state 1 (step S1), and if the new remote controller command is confirmed to be received, the system returns to the standby state 1 (step S1). Further, if it is confirmed that the command for adding the remote controller is not received (step S75) and the command for clearing the pairing is received (step S76), all the data of the radio spectrum pairing is cleared (step S77), and then the system returns to the standby state 7 (step S68); if it is confirmed that the pairing clear command is not received (step S76), the system returns to the standby state 7 (step S68).

As shown in fig. 15, in the standby state 7 (step S68), when the control circuit 121 receives a favorite position setting command for the middle rail 50 or the lower rail 60 to have a specific height (step S78), the first driving module 20 or the second driving module 30 enters a favorite position setting state (step S79). If the control circuit 121 determines that the specific height is not the same as the previous setting during the favorite position setting state (step S80), the configuration of the favorite position where the middle rail 50 or the lower rail 60 has the specific height is completed (step S81), and the standby state 7 is returned after the favorite position setting state is completed (step S68). If the control circuit 121 determines that the specific height is the same as the previous setting (step S80), the previous setting is cleared (step S82), and the control circuit returns to the standby state 7 after ending the favorite position setting state (step S68).

As shown in fig. 16, after the favorite position of the rail 50 or the lower rail 60 with a specific height in the above-mentioned completed configuration (step S81) and the favorite position setting state is ended and the standby state 7 is returned (step S68), the method may further include the following steps: if the middle rail 50 or the lower rail 60 approaches the favorite position, the control circuit 121 receives a favorite position execution command (step S83), and if the number of favorite positions is single (step S84) and the current position is not the favorite position (step S85), the control circuit 121 moves the middle rail 50 or the lower rail 60 to the favorite position (step S86); if the number of favorite positions is one (step S84) and the current position is the favorite position (step S85), the control circuit 121 stops the middle rail 50 and the lower rail 60 and returns to the standby state 7 (step S68). Further, if the number of favorite positions is plural (step S84), the control circuit 121 determines whether the current position is the first favorite position of the middle rail 50 or the lower rail 60 when receiving the favorite position execution command (step S87), and if not, returns to the standby state 7 after moving the current position of the middle rail 50 or the lower rail 60 to the first favorite position (step S88) (step S68); if yes, it is continuously determined whether the current position is the second preferred position of the middle rail 50 or the lower rail 60 (step S89). When it is determined that the current position is not the second favorite position of the middle rail 50 or the lower rail 60 (step S89), the current position of the middle rail 50 or the lower rail 60 is moved to the second favorite position (step S90) and then to the standby state 7 (step S68). When the current position is determined to be the second favorite position of the middle rail 50 or the lower rail 60 (step S89), the control circuit 121 moves the middle rail 50 and the lower rail 60 to the first favorite position and returns to the standby state 7 (step S68).

When the solar radiation adjusting apparatus of the present invention is used, since the first curtain 100 and the second curtain 200 are disposed in parallel to each other, there is no situation of overlapping to increase the thickness, and further, the first curtain 100 and the second curtain 200 respectively have the foldable first air chambers 101 and the foldable second air chambers 201, so that the shielding areas of the first curtain 100 and the second curtain 200 on the building or the vehicle can be changed by extending and retracting the foldable air chambers, the air chambers can save the material usage of the first curtain 100 and the second curtain 200 and reduce the weight of the whole apparatus, and the air chambers have good heat insulation effect (air is not a good heat conduction medium) when extended, thereby saving the cost of air conditioning cost in the room. In addition, when the solar radiation adjusting apparatus is operated, an initial position, an upper limit position, and a lower limit position may be preset for the middle rail 50 or the lower rail 60, so that the middle rail 50 and the lower rail 60 are electrically controlled by the first driving module 20 and the second driving module 30 within a safe range, and the first driving module 20 and the second driving module 30 may be precisely controlled under the control of the first optical encoder 300 and the second optical encoder 400, so that the middle rail 50 and the lower rail 60 reach precise positions. Further, since the speed of the first driving module 20 moving the middle rail 50 is the same as the speed of the second driving module 30 moving the lower rail 60, the middle rail 50 and the lower rail 60 are ensured not to collide with each other in the process of moving simultaneously or moving sequentially, thereby avoiding the problems of twisting or curtain deformation and distortion. Further, the control circuit 121 can determine the relative positions and distances of the middle rail 50 and the lower rail 60 according to the inner through holes a and the outer through holes B on the light shielding discs 301 and 401, for example, when the control circuit 121 can control the relative distance between the middle rail 50 and the lower rail 60 to be equal to or less than the circumferential distance corresponding to the three inner through holes a or the three outer through holes B (which is only exemplary and not limited herein), the control circuit 121 can further control the first driving module 20 or the second driving module 30 to decelerate or stop, so that the relative distance between the middle rail 50 and the lower rail 60 is precisely controlled by the control circuit 121, the first optical encoder 300 and the second optical encoder 400, and therefore, the middle rail and the lower rail can be prevented from being collided when moving in the same direction or in the opposite direction simultaneously or sequentially.

Therefore, the sunshine adjusting device solves the technical problem that accurate adjustment is difficult to carry out according to the relative position of the sun and the earth, and avoids the problems of collision of parts of multiple curtains, thread winding or curtain deformation and distortion and the like, so that the curtains can be accurately controlled, the service life and the durability are improved, and the purposes of easy operation and maintenance for users are achieved.
