Design And Realization Of The Auto-Selection System For Gas Regulator

Gas equipment industry is a rapidly growing industry in virtue of vigorously promoted use trends of state's clean energy and international- ization energy. And the implementation of several large-scale projects such as Western China Gas and Electric Power Transported to the East, the Sino-Russian Gas and Eastern China Sea Oil accelerates the development of the industry. These make natural gas related to industry increases rapidly.Regulator hold the balance in Gas equipment industry, but traditional Selection of Gas Regulator just refer to papery file to get the information about inlet and outlt pressure, capacity, and caliber of valve, which bring in inconvenience. So in this circumstance, use Database technology to realize auto-selection of gas regulator.Current baic database access technique primarily contain ODBC, DAO, RDO, JDBC, OLE DB/ADO, they appear separately on different period and use broadly, some techniques are still very popular now. This paper has compared and researched these basic database access techniques, and the system is realized with Viusal C++ Language by adoption ADO database access technique, which is much popular. Then the most important introduction is ADO database access technique, which is used to access the database of ACCESS. At the same time, the system utilize DLL to realize the process of lookup information in EXCEL. And it has been proved that this system is much more faster than traditional selection of gas regulator, and also in efficiency.
