Ship traffic flow coordination method and system based on model predictive control

ActiveCN119626038Aavoid meetingImprove navigation safetyMarine craft traffic controlState predictionMarine engineering
The invention discloses a ship traffic flow coordination method and system based on model prediction control, and the method comprises the following steps: building a state prediction model, obtaining the real-time navigation states of a ship and an opposite ship, and predicting the navigation states of the ship and the opposite ship in a plurality of time steps in the future according to the real-time navigation states; the meeting point and the meeting moment of the ship and the opposite ship are calculated according to the predicted sailing state, and an optimization function is established with the ship sailing time and fuel consumption minimization of the ship as the target; the constraint condition of the optimization function is set, so that the meeting point is located outside the dangerous water area, the meeting moment is located outside a dangerous time window, and the dangerous time window is the time period when the opposite ship travels in the dangerous water area; solving the optimization function to obtain the optimal control parameter of the ship, and updating the sailing state of the ship in the next time step according to the optimal control parameter; and repeating the steps until the ship arrives at the destination.

A loading and unloading ladder for cigarette packets

ActiveCN224413537UEasy to installmaintain stabilityRight triangleMechanical engineering
The utility model relates to a loading and unloading ladder for carrying cigarette packets, which comprises a supporting plate, a first supporting column arranged at one side of the top end of the supporting plate, a second supporting column arranged at the other side of the top end of the supporting plate, the first supporting column and the second supporting column being arranged oppositely, a first ladder arranged at the top end of the supporting plate, the other end of the first ladder being connected with the top end of the first supporting column, a second ladder arranged between the first supporting column and the second supporting column, a second platform arranged at the top end of the second supporting column, and a lifting mechanism arranged at the top end of the second platform. The supporting column at the bottom end of the second platform supports the second platform synchronously, one end of the supporting column is connected with the bottom end of the second platform, the other end of the supporting column is connected with the second supporting column at an angle of 45 degrees, the supporting column, the second platform and the second supporting column form a right-angled triangle, the triangle has stability, and the second platform is more stable in installation.

A range hood and its control method

ActiveCN113074397BReduce space consumptionIncrease operating spaceDomestic stoves or rangesLighting and heating apparatusMechanical engineeringPhysics
This invention relates to the field of kitchen appliance technology, specifically to a range hood and its control method. The range hood includes: a rear shell for collecting smoke; a front shell for collecting smoke, horizontally disposed on the front side of the rear shell and movably connected to it; and a drive structure adapted to directly or indirectly drive the front shell to extend or retract relative to the rear shell. The range hood provided by this invention, by movably connecting the front shell to the rear shell and allowing the front shell to extend or retract relative to the rear shell, reduces the space occupied by the range hood during operation, providing more operating space for the user and preventing head bumps.
