Design And Implementation Of Embedded System Software In Industrial Control

With the rapid development of computer and micro-electronics technology, embedded system which is one of important applications, has been applied in many fields. In recent years, the practice of embedded system in the industrial control becomes more and more extensive. This thesis discussed the design and implementation of embedded system software in industrial control, aim at establishing uniform software platform of an entire embedded control system, which consists of embedded real-time OS, embedded configuration software, softPLC and etc. The thesis began with an overview of the concept, development, hardware and software of embedded system. It analyzed embedded control system and related software, including embedded real-time OS, softPLC and embedded SCADA. Then it briefly introduced the embedded control system software platform and its prospect future.After that, the thesis proposes software framework of the platform and analyzed the key part of the software based on the author's research in embedded control system. According to the result of analysis, the thesis discussed the implementation of the main models of the platform in detail, including embedded real-time OS, real-time database management and communication, human interface software and etc. Then the thesis provided a demo to test the performance of the platform. The test is based on the PC104 embedded mainboard and embedded RTAI real-time OS. The test results manifest the platform has hard real-time capabilities, easy configuration and etc.In the end, the thesis analyzed the related models which needed to be improved and developed in the platform. Then, the future application of embedded system in industry control was prospected.This thesis provided us with a full description on the design and implementation of the embedded system software in industrial control,especially on Linux. It will be the guidance for research and development in embedded control system.
