Design And Imlementation Of Embedded Control System Based On Wince And ARM9 For Biologic Fermentation

Biologic fermentation industry has been a key component of contemporary biologic industry and turn out to be a prevalent usage in the production of food and medicine, which demonstrate a bright future and prosperous development in market. However, as biologic fermentation is a complex biochemical process combined with a huge amount of control variables and a high cohesion itself, it's very hard to perform a effective control on it.Thus, according to the profile of biologic fermentation process and the current market requirement, a detailed description is performed on the design, implementation and improvement of embedded control system for biologic fermentation. With the process of biologic fermentation as main stream, a control scheme, a real time system supervisory software and a measure to improvement the integration are discussed as follows,(1) A brief introduction on the concept and characteristics of biologic fermentation is conducted at the beginning stage; followed by the current status and production procedure of biologic fermentation industry; followed by an introduction of the fermentation cylinder and the control system developed by our lab, demonstrating the foundation of my tasks.; followed by an introduction of the concept and characteristics of integrative industrial computer.(2) Give out an analysis on customer requirements and a description of function modules of real time supervisory software. Then the hardware and software development environment is introduced, followed by the design and implementation of each modules in software and the difficulties encountered and corresponsive solution.(3) A comparison between the current and target product is conducted, followed by a discussion of the improvement aspects of current product. Then an attempt to improve the system density of integrity is carry out: Implementation of IIC communication between ARM CPU and bottom layer data collection module. As the module is developed on Wince.NET platform, the procedure of Windows CE driver developing is introduced and pieces of key code are in analysis.(4) Finally give out the summary and outlook of the thesis.
