Description

Technical Field

[0001] The present invention relates to the field of photovoltaic workshop automation, and in particular to a photovoltaic split silo high-integration controller based on an embedded platform. Background Art

The production of photovoltaic cells has off-seasons and peak seasons. In the off-season, not many people may be needed, but in the peak season, people need to be recruited to achieve full production. It is difficult to recruit people in a short period of time, and they also need to be trained before they can take up their posts, which may cause the best time to be missed, affecting photovoltaic production and reducing the productivity of photovoltaic cells. Therefore, the automation of photovoltaic workshops is a trend. The automation of workshops is achieved through AGVs and robots. The line can be stopped during the off-season. The existing AGV scheduling system usually performs AGV scheduling according to the pre-set scheduling logic. However, this method often cannot adapt to complex and changeable production environments, and has defects such as being unable to control, track, operate, and display information, resulting in poor scheduling flexibility, which in turn affects the efficiency and real-time requirements of AGV scheduling, resulting in low material handling efficiency and prone to errors.
