Equal-diameter SOP setting method, system and device based on big data and storage medium

Abstract

According to the equal-diameter SOP setting method, system and equipment based on big data and the storage medium, basic source data of equal-diameter nodes in the single crystal drawing equal-diameter process are processed and screened and converted into a plurality of data sets easy to recognize and mark in the equal-diameter nodes, a model is established, analysis calculation and fitting optimization are carried out, and the equal-diameter SOP setting efficiency is improved. Obtaining an optimal growth rate model in an equal-diameter process; obtaining basic source data of the relative liquid opening distance of the equal-diameter nodes; the process parameters are screened and converted into process parameters easy to identify and mark; and obtaining the growth rate of the current node, comparing the growth rate with the optimal growth rate model, and adjusting the growth rate or the power of the main heater according to a comparison result. According to the technical scheme, equal-diameter SOP method setting can be effectively carried out in big data and deep learning, big data analysis is utilized, an optimization scheme is executed, big data and deep learning are organically combined, self-optimization of the equal-diameter SOP model is achieved, the making and revision efficiency of the equal-diameter SOP model is improved, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic single crystal pulling and production, and in particular relates to an equal diameter SOP setting method, system, equipment and storage medium based on big data. Background technique [0002] The growth process of Czochralski single crystal mainly includes working steps such as temperature stabilization, seeding, shoulder placement, equal diameter, and finishing. In the process of equal diameter of Czochralski single crystal, the setting of equal diameter SOP currently requires technical personnel to be specially responsible for formulation and revision. However, the manual formulation and revision of SOP can only be revised one by one in different furnace types, different systems, and different residual material weights, etc., and cannot be refined to specific furnaces, while single crystal furnaces are individual, and a set of SOPs cannot satisfy all furnaces. characteristic. [0003] The...
