Research On The Automaiton Recording Information Management System And Application Of The Computer Serial Port

With more and more important social role, people pay more and more attention to the research on the technologies, management and application of information system field. Actually, the database work as access and management for the information resources, whose development is the development and application of the database-based management system. The database management system has become the indispensable and important component in the daily company management work.With the flourish development of the industrial automation and communication technologies in various enterprises, especially in the IT R&D enterprise, the application of the computer serial port has reached an essential level. Therefore, the research on the computer serial port has its very important social value. Combined with the application of the computer serial port, the development of the automation recording information management system integrates the technologies, such as computer serial port communication techniques, Access database techniques, ADO.NET database access techniques, the design of the Windows Forms application on the.NET platform and so on.Firstly, based on systematic research in this direction, the theoretical basis for designing the computer serial port is introduced, including the application of the port techniques and the protocol standard of the RS232 serial port. At the same time, the theoretical of the hardware model design is described:the relationship between the test result from the AS7002 and the pin voltage of the AS7002's motherboard chipset. And from the perspective of information system development, the theoretical foundation of the information system development is introduced, including analysis and design methods of the Object-Oriented system, C#.NET overview, Access database techniques and the overview of the Windows Forms application design on the.NET platform.Secondly, according to the basic theory, the key technologies and its achievement of the system hardware model is researched. Abandoning the traditional manual record and taking the automatic record mode, so, the key technologies in the section of introducing the analysis and design for the system hardware module are as follows. First, the work background of the AS7002 and the computer serial port MSComm controls are introduced briefly. Second, the design process of communication achievement, not the traditional means of communication with RXD and TXD but the innovative application presented in this paper, between the AS7002 and the computer serial port is given. Therefore, the key technologies and implementation methods of the system hardware modules is introduced in detail.The information management system has become the indispensable and important component management system in various enterprises. In the application of the information system, according to the different requirement and the realistic environment, doing the development for the information management system is the development trend of the information system. Therefore, at the last of this paper, the key technologies and its implementation of the system software environment are introduced as follows:C#.NET to access Access database technology through ADO.NET, the whole system analysis and design for the software environment, technical solution for some modules of the software environment and the key technology of dealing with Access database data in C#.NET. At last, the final automation recording information management system has been achieved according to the application environment, requirement and the realistic environment. The powerful function and User-friendly interface is provided by final system. Because of this, the work efficiency and the data management efficiency are improved significantly.
