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 present invention provides a method and system for controlling the rotation of a heliostat. The control method includes: acquiring a first preset control angle, motion parameter information of the heliostat, and delay information of a reversing valve; Set the control angle, the motion parameter information of the heliostat and the delay information of the reversing valve to calculate the actual control time required for the heliostat to rotate the first preset angle; send the actual control time to the user's terminal and / or motion execution terminal sent to heliostats. By calculating and analyzing the actual parameters of the heliostat itself, calculating the actual control time, taking the inertia factor of the heliostat itself and the delay factor of the reversing valve into consideration, the precision of the heliostat control is improved and the heliostat control is reduced. The error of the rotation angle of the mirror can improve the efficiency of absorbing solar energy of the heliostat, reduce the power consumption of the regulation of the heliostat, and improve the reliability of the heliostat.

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...
