| Embedded systems are widely used in daily life, the military, industrial production .When constructing the development of embedded system; we need define the application model of system. The model in building the entire system can increase the efficiency of development, and play an important role in the maintenance and user convenience. The main purpose of the thesis is to study the model of embedded systems development and the construction, at the same time, based on which to develop the actual project.The main research contents of this thesis are as follows:1. After comparing and analyzing architectures of B/S and C/S, a new method of software application model is putted forward. The method makes the platform of embedded systems more efficiency in practical application.2. Studying the system architecture of YL44B0X hardware platform, configuring and transplanting the uClinux operating system, Berkeley DB and BOA Web Server.3. Developing the Embedded Web Server and the CGI Common Gateway Interface. Realizing the configuration and the management of the embedded platform through browser and improving the system's remote-distance embedded interactive capabilities.4. The embedded data transmition server and the upper management system are developed. By using VC program language to design ActiveX middleware so as to realize the unified interfaces between different development languages and software reuse under Windows environment is provided. The upper management systems are developed, which make the communication between embedded servers and remote client more efficiency.5. Under the embedded system platform, embedded platform parameters of the system is configured as well as the dates acquired from the field are managed by Berkeley DB .In this thesis, the application project was used that based on the model of C/S,B/S architectures and embedded databases application, so a new method and model was provided for the embedded platform and application . |
