[0027] Working principle: In the one-key expansion process of the device, the remote control 39 sends a one-key expansion command to the industrial computer 35 through the wireless transmission station. After receiving the one-key expansion command, the industrial computer 35 first reads the current value of the rotary electric cylinder 16 through the electric cylinder controller 31. If the current position of the electric cylinder is not in the middle position, the electric cylinder is first controlled to return to the middle position, that is, the horizontal angle of the target frame is adjusted to the middle position, and the target frame angle sensor 34 value is read. If the target frame angle sensor 34 value is less than the target frame base 18 sensor value plus 30°, the industrial computer 35 sends a hydraulic cylinder 11 push command to the relay 37, controls the hydraulic system 20, and closes the hydraulic cylinder 11 push solenoid valve, thereby pushing the oil. The cylinder makes the vertical angle target frame value. When the target frame angle sensor 34 value is greater than or equal to the target frame base 18 sensor value plus 30 degrees, the industrial computer 35 sends a hydraulic cylinder 11 stop pushing command to the relay 37 to control the hydraulic system 20 hydraulic cylinder 11 to push the solenoid valve off, thereby stopping the hydraulic cylinder 11 from pushing out. The industrial computer 35 sends a control command to the electric cylinder controller 31 to control the upper middle electric cylinder 6 and the lower middle electric cylinder 21 to retract. The upper middle electric cylinder 6 and the lower middle electric cylinder 21 pull the upper middle target frame surface 2 to unfold. When the electric cylinder reaches the specified position, the upper middle electric cylinder 6 and the lower middle electric cylinder 21 stop moving. Then the industrial computer 35 sends a control command to the electric cylinder controller 31 to control the upper left electric cylinder 23 and the lower left electric cylinder. 24 retract command, the upper left electric cylinder 23 pulls the upper left target frame surface 5 to unfold, and the lower left electric cylinder 24 pulls the lower left target frame surface 3 to unfold. When the electric cylinders reach the specified position, the upper left electric cylinder 23 and the lower left electric cylinder 24 stop moving. Then the industrial computer 35 sends a cylinder retraction command to the electric cylinder controller 31 to control the upper right electric cylinder 27 and the lower right electric cylinder 28. The upper right electric cylinder 27 pulls the upper right target frame surface 4 to unfold, and the lower right electric cylinder 28 pulls the lower right target frame surface 7 to unfold. When the electric cylinders reach the specified position, the upper right electric cylinder 27 and the lower right cylinder 28 stop moving. This completes the one-key unfolding of the target frame surface. After the one-key unfolding is completed, the upper left target frame surface 5 and the lower left target frame surface 3 can be adjusted through the remote control 39. , the upper right target surface 4, the lower right target surface 7, and the vertical and horizontal rotation angles of the target. When folding is required, the remote control 39 sends a one-touch folding command to the industrial computer 35 via a wireless transmission station. After receiving the one-touch folding command, the industrial computer 35 first reads the current value of the rotary electric cylinder 16 through the electric cylinder control. If the electric cylinder's current position is not in the middle position, it first controls the electric cylinder to return to the middle position, i.e., adjusts the horizontal angle of the target to the middle position. The industrial computer 35 sends an extension command to the electric cylinder controller 31 to control the upper right electric cylinder 27 and the lower right electric cylinder 28. The upper right electric cylinder 27 pushes the upper right target surface 4 to fold, and the lower right electric cylinder 28 pushes the lower right target surface 7 to fold. When the electric cylinders reach the designated positions, the upper right electric cylinder 27 and the lower right electric cylinder 28 stop moving. The industrial computer 35 sends an extension command to the electric cylinder controller 31 to control the upper left electric cylinder 23 and the lower left electric cylinder 24. The upper left electric cylinder 23 pushes the upper left target surface 5 to fold, and the lower left electric cylinder 24 pushes the lower left target surface 3 to fold. When the electric cylinders reach the designated position, the upper left electric cylinder 23 and the lower left electric cylinder 24 stop moving.The industrial computer 35 then sends a push command to the electric cylinder controller 31 to control the middle upper electric cylinder 6 and the middle lower electric cylinder 21. The middle upper electric cylinder 6 and the middle lower electric cylinder 21 push the middle upper target frame surface 2 to fold. When the electric cylinder reaches the designated position, the middle upper electric cylinder 6 and the middle lower electric cylinder 21 stop moving. The industrial computer 35 then sends a retraction command to the hydraulic cylinder 11 to the relay 37 to control the hydraulic system 20 to close the retraction solenoid valve of the hydraulic cylinder 11, thereby pulling back the cylinder and lowering the vertical angle of the target frame. When the value of the target frame angle sensor 34 is less than or equal to the value of the base angle sensor 36, the industrial computer 35 sends a stop retraction command to the relay 37 to control the hydraulic system 20 to open the retraction solenoid valve of the hydraulic cylinder 11, thus completing the one-touch folding of the target frame surface.
