The Development And Development Method Research Of Embedded Internet Remote Monitor And Control System

With the evolution of the manufacturing industry, the embedded system becomes the key technology in this industry. The embedded system has been used in so many fields, such as industry control system, information appliance, communication equipment and medical instrument. Currently, the research and development based on embedded system has become the one of the most important areas in the computer software and hardware technology.The embedded Internet remote monitor and control technology is the hot point of industry control research field, and also a challenging topic. Many IT research institutes and developers are engaging in this area, and some theories and application results come out. But the development of the embedded system based on RTOS is different from the traditional microchip system development. There is no one mature formalized method for the system requirement, analysis, design, programming and testing. And these limit the development of the embedded system based on RTOS. This thesis focuses on the research of the embedded Internet remote monitor and control technology, integrating UML and development method of embedded system. The thesis provided an approach for the development of the embedded system. And the thesis implements an prototype of an embedded Internet remote temperature monitor and control system.By raising questions, researching theory and methods and implementing a practical application, the thesis does deep research works as following:1. By using UML and doing software/hardware cooperation design for embedded system, the thesis develops a visualized development method of the embedded system. The embedded system modeling based on UML will not only formalize the system development procedure, but also make the project members capable of finishing system requirement, analyzing, designing, programming and testing procedures in unified way.2. Applying the visualized development method of the embedded system based on UML into the development of embedded Internet remote temperature monitor and control system, and verifying the feasibility and effectivity of the method.3. Under deep research of the technical characteristics and HCI interface of the blue-tooth, the thesis implements the short range blue-tooth wireless communication between embedded Web server and the digital temperature measurement instrument. It is valueful for the blue-tooth application into the field of wireless monitor and control.4. Based on the μC/OS-Ⅱ core, the embedded Web server realizes the local monitoring task, blue-tooth communication task and single procedure loop Web service task. By inter-task communication technology in μC/OS-Ⅱ, different tasks are integrated together. Because μC/OS-Ⅱ hides the hardware and provides multi-task support for upper level software with real-time and great stability, programming implementation of the system is simplified and the code quality is promoted.5. Porting is the key step in the embedded system development, which makes quick development possible. This thesis studies the micro TCP/IP stack (uIP). Implement the porting of it on ARM and u C/OS-II platform, through modification of the configuration file and network driver.The prototype of the remote temperature monitor and control system has been implemented and verifed in local LAN lab environment. The research work of this thesis, including the application research in embedded Internet remote monitor and control technology which is based on u C/OS-II, and method research of embedded system development, provides a helpful guidance to the embedded system development in other application fields.
