Problems solved by technology
The improved Siemens method is currently the mainstream polysilicon production process. Due to the complexity of its production process, the R&D and improvement of core technical equipment and the optimization of key processes need to undergo repeated small tests and pilot tests. The research and development cycle is long and the investment in research and development is large; Massive relevant parameters accumulated over many years of operation have not played a fundamental and reference role in the improvement and optimization of subsequent processes

Description
technical field [0001] The invention relates to a production method of polysilicon, in particular to an intelligent production method and system of polysilicon. Background technique [0002] Since the 1990s, the trend of economic globalization has been obvious. Industrial R&D, production, and services have been continuously integrated in the direction of globalization. The development of network and information technology has led to the emergence of the world factory. The "Smart Photovoltaic Industry Development Action Plan (2018-2020)" clearly pointed out to promote the deep integration of the Internet, big data, artificial intelligence, etc. Intelligent integration and operation and maintenance. Therefore, intelligentization has become an inevitable trend of industrial development. [0003] Polysilicon is the "cornerstone" of the microelectronics industry and photovoltaic industry, and the most basic raw material for the information industry and new energy industry. The...
