Abstract: This paper briefly describes the background, objective and content of the research on the upgrading of TW-2 Hump Automatic Control System. The system structure, the database design and the software module design of the upgraded system are described in detail. An integration server is added to the system structure to enhance the data service and the interface service ability. Microsoft SQL Server is used as the database and the relational data structure is redefined. The software programs are redesigned for the user operation layer, the integration management layer, the upper control layer and the lower control layer. The humping route module serves as an example to describe the control flow of the system in detail. The upgraded system has passed the test and verification, the software functions are perfect, the human-computer interaction is friendly and the maintenance function is improved.
