The application discloses a setting method, a control method and equipment of a mower. When a visual obstacle-avoiding area is set for the mower, a terminal device receives an operation instruction, generates a control instruction and sends the control instruction to the mower to drive the mower to move. The mower determines a moving track in real time based on its own position information, and sends a creation confirmation request to the terminal device. After the terminal device confirms, the mower triggers the establishment of the visual obstacle-avoiding area which is accurately corresponding to a physical path. The visual obstacle-avoiding area established by the application can more accurately correspond to the real contour of the actual passable area such as a stone road and a manhole cover in a site. The work map generated based on this can reliably guide the mower to pass through the visual obstacle-avoiding area efficiently and safely in subsequent work, and is beneficial to improving work efficiency. The technical scheme of the application can be widely applied to the technical field of the mower.

The invention discloses a method and a device for predicting a non-deposition condition of sand-carrying migration of a tubular column. The method comprises the following steps: within preset calculation physical time, performing numerical simulation on a flow field in a tubular column under a single independent variable working condition by utilizing a pre-established sand migration simulation model, and monitoring sand mass flow at an inlet and an outlet of the tubular column to obtain simulation and monitoring results; based on the mass flow of the sand at the inlet and outlet of the tubular column in the simulation and monitoring results, obtaining the sand mass at the inlet and outlet of the tubular column; determining the discharge rate of the sand grains according to the mass of the sand grains at the inlet and the outlet of the tubular column, and determining the minimum sand carrying flow under the single independent variable working condition by combining a preset flow rule; and fitting the minimum sand carrying flow and the single independent variable to obtain a fitting relationship, and predicting a sand migration non-deposition condition under a given independent variable condition by utilizing the fitting relationship. The migration condition of sand grains in a pipe column can be accurately simulated, so that the migration non-deposition condition of the sand grains can be more scientifically and accurately determined, and smooth discharge of the sand grains is ensured.
