| This article in view of our country electric railway contact network engineering design and the construction present situation, elaborate development of engineering calculation system the necessity. In detail introduce the contact network engineering calculation system design thought and the principle, the overall demand, the functional design, and the technical characteristic as well as its realization process. This system development and success application not only have solved the crucial technical difficult problem for the enterprise, moreover brings the considerable economy and the social efficiency for the enterprise, has become the enterprise to construct the essential modernized tool.The computation software of Contacted-network construction, It develop and include backstage supporter foundation and maintain and front development two of application program of data base mainly. Demand and set up data consistency and better integrality as to the former, Storehouse of the data with good security. Require application program to be function complete the latter, apt characteristic of using etc..By surveying and analyzing lots of datum, select Visual Basic presented because of its objective tools in Win32. VB offered a series of ActiveX operating a data-base. It can give you a short-cut to build up a prototype of system application. The prototype could be modified and developed till users are satisfied with it.Contacts net construction computation software to research and develop successfully, and the investment job location carries on the data computation many times, its computation accuracy obtains the actual confirmation. Because system itself has the contact surface in a friendly way, may revise, is easy operate, the accuracy higher characteristic, have been widely used. |
