Abstract:For the company dispatch automation room’s wirings hadn’t drawing management and the labels were not standard, a set of computer room network wiring management software was developed independently. Firstly, the functional requirements of visual wiring management software to deal with drawing network wiring and generating label information automatically were analyzed, and the software architecture based on MVC model theory was designed; Secondly, the implementation of the key functions based on QT graphics library platform were elaborated, including the construction of the graphic class, the generation of components library that can be configured, the graph serialization and anti-serialization operation, topology search, the attribute management of components and the automatic generation of label information; Finally, the actual usage and application effect of the software was illustrated through an example. The results of application show that drawing the entire room network connection diagram and input the device attribute information help to improve the efficiency of network fault diagnosis and reduce the risk of system operation and maintenance.
