Problems solved by technology

[0003] During the operation of the heliostat, when the target position is reached, the heliostat is controlled to stop immediately, but due to the closing delay of the reversing valve and the inertia of the heliostat, the final position of the heliostat will exceed the target position, and the tracking accuracy Exceeding 1mrad, this error cannot be reduced in the prior art

Abstract

The invention provides a heliostat rotation control method and system. The control method comprises the steps that a first preset control angle, the motion parameter information of a heliostat and thedelay information of a reversing valve are acquired; the actual control time needed by the heliostat to rotate a first preset angle is calculated according to the first preset control angle, the motion parameter information of the heliostat and the delay information of the reversing valve; and the actual control time is sent to a user terminal and / or the motion execution terminal of the heliostat. By calculating and analyzing the actual parameters of the heliostat, the actual control time is calculated. The inertia factor of the heliostat and the delay factor of the reversing valve are takeninto account. The control accuracy of the heliostat is improved. The rotation angle error of the heliostat is reduced. The efficiency of solar absorption of the heliostat is improved. The power consumed by heliostat regulation and control is reduced. The reliability of the heliostat is improved.

Description

technical field [0001] The invention relates to the technical field of heliostat tracking, in particular to a method and system for controlling the rotation of a heliostat. Background technique [0002] The heliostat is driven by the hydraulic station to expand and contract the hydraulic cylinder to achieve the purpose of rotation. The angle control accuracy of the heliostat is required to be within ±1mrad. The reversing valve of the hydraulic station adopts an ordinary reversing valve, and the angle of the heliostat is fed back through the inclinometer. [0003] During the operation of the heliostat, when the target position is reached, the heliostat is controlled to stop immediately, but due to the closing delay of the reversing valve and the inertia of the heliostat, the final position of the heliostat will exceed the target position, and the tracking accuracy Beyond 1 mrad, this error cannot be reduced in the prior art. Contents of the invention [0004] The technica...
