The method as described in claim 9, characterized in that, When the net cage is lifted to the preset position, the net pulling mechanism (4) is controlled to pull the net pieces in the net cage to the conveying mechanism (5), including: when the lifting position signal is received, the net pulling mechanism (4) is controlled to pull the net pieces in the net cage to the conveying mechanism (5), and after the net pieces have completed rotation, the net pieces are transported to the left and right net adjusting mechanism (7). When the mesh is above the lifting and rotating mechanism (6), the lifting and rotating mechanism (6) is controlled to lift the mesh a preset distance, so that the mesh is detached from the conveying mechanism (5), and then the mesh is rotated to a preset direction so that the mesh can cover one side of the roadway roof when it is raised. After the mesh has completed the rotation, the mesh is controlled to fall down the preset distance so that the mesh returns to the top of the conveying mechanism (5). This includes: when the mesh arrival signal is received, the lifting and rotating mechanism (6) is controlled to lift the mesh a preset distance, so that the mesh is detached from the conveying mechanism (5), and then the mesh is rotated to a preset direction so that the mesh can cover one side of the roadway roof when it is raised; when the rotation is in place signal is received, the lifting and rotating mechanism (6) is controlled to drive the mesh down the preset distance so that the mesh returns to the top of the conveying mechanism (5). When the mesh is transported to the left and right mesh adjustment mechanism (7), the left and right mesh adjustment mechanism (7) is controlled to adjust the mesh to the position directly opposite to the lower left side of the roadway roof and fix it, or to adjust the mesh to the position directly opposite to the lower right side of the roadway roof and fix it, including: when the transport arrival signal is received, the left and right mesh adjustment mechanism (7) is controlled to adjust the mesh to the position directly opposite to the lower left side of the roadway roof and fix it, or to adjust the mesh to the position directly opposite to the lower right side of the roadway roof and fix it.

12. A computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that, When the processor executes the computer program, it implements the method of any one of claims 9 to 11.

13. A computer-readable storage medium, characterized in that, The computer-readable storage medium stores a computer program that, when executed by a processor, implements the method of any one of claims 9 to 11.

14. A computer program product, characterized in that, The computer program product includes a computer program that, when executed by a processor, implements the method of any one of claims 9 to 11.
