Through the steps, a deployment mirror field of the heliostat is divided into a plurality of deviation rectifying areas, the heliostat is a heliostat in a photo-thermal power station adopting a tower type fused salt photo-thermal power generation system, and the heliostat is used for reflecting sunlight to a heat absorber of the photo-thermal power station; randomly selecting heliostats to enter a deviation rectifying queue in a target deviation rectifying area of a plurality of deviation rectifying areas; according to a preset deviation rectifying scheme, the heliostats in the deviation rectifying queue are rectified in parallel, the preset deviation rectifying scheme is used for reducing mutual interference among the heliostats, the deviation rectification is used for rectifying deviation of the heliostats when the heliostats track the running track of the sun, and the technical problem of low deviation rectifying efficiency in the related technology can be solved.
The utility model provides a random screening heliostat constitutes rectifying array includes:
1) the rectifying regions are divided according to the viewing angle regions of the N rectifying cameras, for example, N is 8, and the rectifying cameras can be divided into 8 large sectors according to the number and the orientation, each large sector covers a 45 ° viewing angle, each large sector is divided into 8 small sectors, the whole mirror field is divided into 8 × 8 sectors or 64 sectors, and the 64 sectors include all 11935-surface heliostats in the mirror field.
2) Randomly selecting heliostats to enter a deviation rectifying queue:
setting different deviation rectifying heliostat numbers M for each region according to different seasons, for example, the deviation rectifying number of each small fan-shaped region is set as 20 heliostats in spring and autumn, less than 20 heliostats in winter and more than 20 heliostats in summer;

After the deviation rectifying queue is generated preliminarily, the deviation rectifying queue is checked, and if the heliostat is in a fault state, the heliostat in the fault state is deleted (the duplicate item and the faulty heliostat are deleted together for execution).
3) Selection of a rectification heliostat in intelligent rectification: because the correction is carried out in a multithreading mode, the mutual interference of a plurality of heliostats can occur during correction, so that the algorithm is optimized, and the probability of mutual interference is reduced; (the selected heliostats are divided into 8 cameras, each camera has 8 zones, then each zone randomly selects the heliostats, and the following 4 steps perform zone division and random on the basis of randomly selecting the heliostats).

When the heliostats with the initial angle parameters removed are taken and inserted into the temporary tables, if the number of the heliostats is less than the number of the heliostats, all the heliostats are placed into the temporary tables, and otherwise, only the front heliostats are selected and inserted into the temporary tables.
In step S205, the number of mirrors in the temporary table (temporary table is used to store the randomly-taken heliostat number) is taken and stored as effectievenum.

Step S218, update the heliostat state of the bcs _ result _ update (representing the current heliostat deskew result state table, if the heliostat participates in deskew today, the value of the heliostat is changed) table.
In step S219, in the process of executing the above steps, the duplicate entry may be deleted, and the failed heliostat may be deleted at the same time.
The distribution diagram of randomly selecting heliostats to enter a rectification queue mirror field is shown in fig. 3, the left side is the mirror field distribution of the heliostats, different gray scales represent different states (such as successful rectification within 30 days, successful rectification before 30 days, non-rectification, preparation for rectification, insufficient rectification data, manual reset of rectification states, insufficient rectification duration and unsuccessful rectification calculation), the left side center represents a heat absorption tower, and the right side represents a heliostat queue (fig. 3 is only used for schematic representation, characters are not clear and do not affect the schematic representation). If the actual production effect is considered, the deviation rectifying strategy can be replaced by a completely random strategy, but the deviation rectifying is not targeted, mutual interference is caused in the deviation rectifying process, the deviation rectifying efficiency is not high, and the like. The invention mainly comprises the following steps: generating a correctable queue based on the rule; the heliostats generated by the deviation rectifying queue have randomness, so that the large-area bundling and deviation rectifying conditions are avoided; after the deviation rectifying queue is generated, the deviation rectifying queue can be visually displayed; after the correction queue is generated, manual adjustment can be carried out; in the deviation rectifying process, the simultaneous deviation rectifying of adjacent heliostats can be avoided, and the correctness of the deviation rectifying effect is ensured.
