The Application Of Computer Simulation And Emulation And Communication Technologies In Multi-Gas Station-Management-System

So far, Simulation has become a necessary step in the whole design of a product, which not only can reduce the study periods, but also can save the costs.This paper is put forward to test the Multi-Gas Station-Management-System software. The Multi-Gas Station-Management-System is a kind of management software including pump-watching, tank-watching, clients management, finance management and reports printing etc, which is to approve the gas station's work efficiency. During the programming of the management system software, it's necessary to test all of its function modules to be sure of its stability. To achieve this aim, an environment that is similar to that of the real gas station is needed. Because the gas station's equipments are very big and expensive, it's impossible to construct a same test platform in the laboratory. The computer simulation technology is considered to simulate the real equipments. There are many manufacturers who produce these equipments, which differ from each other. So in this paper we mainly discuss their communication interface and protocols and their realization by software of those equipments, which are widely used in most gas stations. The author also discusses the hardware and software design of the real Huber.Because this management system is based on multi-gas station, there are data transmissions between the gas stations and the management center. In this paper the author introduces two methods, Modem and RAS, to accomplish file transfer.
