Design And Implementation Of Application Ucos-ii Phase Ac Induction Motor Soft Starter

It is found that the hard reset way to start three-phase motor which does a lot of harm to motors is still widely used by widely research at present, while soft start which do little harm and energy-saving is not a very wide range of promotion. First there is still no uniform products to update the motor directly, second, the cost is not low enough. To promote the soft start way, two problems must be resolved:portability and low cost. From this perspective, a soft start way based on lightweight open-source-based real-time operate system uC/OS_â…¡and classic ARM chip is designed.The research content of this topic more, study a longer period, pre-delivery preparation difficult, very difficult to draw clear at the outset, the needs and design, this incremental model used to guide the research and development work. In the incremental model, the software is as a series of incremental building blocks to design, implementation, integration and testing, each component is formed by multiple interacting modules, each one has a component for the development of the analysis of components, design, coding and testing links, until the completion of each component. In appropriate software development model under the guidance of topics designed to achieve the desired purpose.
