Chain Of Gas Stations Computer Network Management System Development

Nowadays , there exist some limitations in The gas-stations of our country, such as the refueling devices are behind the times and the management is disordered. This not only brings much inconvenience to user, but also make against management of the gas-stations. For this problem, this paper introduces the basic theory of establishing a computer management network system firstly, and then a feasible scheme of constructing a computer management network system is brought forward after all-things considering the idiographic circumstances of the gas-stations construction. In the scheme the paper mostly solve the question about the transmission of teledata through PSTN (Public switch telephone network). I design a modem transmission protocol by myself in order to satisfy the request of coherence, reliability, security of data.Finally, using an example of computer management network system construction and put it in practice in a chain gas-station. This paper describes in detail how to use the computer management network system and its development in future.
