With the rapid advancement of the guidance for port transformation and upgrading, in view of the lagging automation of bulk terminals, the low level of intelligent information, and the urgent needs for the transformation and upgrading of bulk terminals, this paper optimizes the central control system for bulk grain transportation, and implements the framework, technology, and functions of the central control system for bulk grain transportation. Based on the research of the basic functions of the existing central control system for bulk grain transportation, combined with actual needs, the functional characteristics of the central control system are optimized and researched. The warehouse preparation and transfer process is optimized, the web publishing function is added, the information management is optimized, and the alarm function is improved. The overall characteristics and intelligent level of the central control system for bulk grain transportation is improved, which has guiding significance for the intelligent construction of bulk grain transportation in ports.
