The Design Of Gas Station Automation System And The Research Of WDM Device Driver Development

In light of the current state of the gas station system, based on analyzing the requirement of the daily work of the gas station and considering its requirement in the future, the paper introduces the development and implementing of the gas Station automation system with management and monitoring functions. The general theories of software engineering and systemic engineering and MIS are used. Furthermore, the paper makes some studies of the device driver development of Windows Driver Model.In the first chapter, the paper mainly introduces some basic concepts of Integrated Automation System and some methods of software engineering and its engineering-oriented background. In the second chapter, it brings forward the general methods of system analysis and the general principles of system design, elaborates the requirements of the gas station automation system, plots out the general functional structures. After then, the database system is developed with the theories and the methods of the database application system. In the third chapter, with a view of the real-time and reliability and the saving of system resource, the system of asynchronous serial communication is designed successfully based on the multi-thread technology and message mechanism with Delphi developing tool, the communication is very well between the greasers and the PC. In the succeeding two chapters, in the firstly, the paper analyzes the requirements of the two systems of monitoring in real time and IC managing in detail and layouts the two systems functions, then develops and implements the two systems with the methods of developing software with VB developing tool. The developed systems have good security, portability and good human-machine interface. In the sixth chapter, on the base of the development of the card reader driver and link to the fashion technology of the device driver development named WDM, the paper makes some studies in the methods and the realizations and some settlements for the pivotal technology of WDM driver development. At last, the paper gives some summarizations and some prospects.During the development of the system, the idea of software engineers is always emphasized; the project is processed strictly from requirement analysis, design, development, and test to implementing. And the ideal of systemic engineering and software engineering impenetrate to the project. The system has applied in WUXI and LIANYUNGANG oil station.
