Can Be Customized Domain-oriented Embedded Middleware Technology Research

It is a surging tide that the technology of networked embedded computing is applied to all fields, companied with which the traditional sewing equipment industry has been suffering great changes. And after a long mechanical and electric sewing period, the new-type intelligent sewing equipment, which is developed with the embedded system technique, has become the favorite son of international market.China is the primary consumer of sewing equipment, so it is of great value to overcome the key technology of intelligent sewing in order to convert "Made in China" into "Created in China". Therefore, with the National Development and Reform Commission (NDRC) project named by "Embedded Software System for Seriate Intelligent Sewing Equipment" in the background, the thesis does research on the embedded middleware for intelligent sewing equipment, which benefits from the xi'an industrialization project named by "Embedded Software System of Intelligent Electro-pattern Sewing Machine". The contributions are as follows.1. A hierarchical middleware is proposed for intelligent sewing equipment, and the general-function middleware for intelligent sewing is designed and implemented. Accordingly new application can be customized on the basis of this middleware, by which the quality of software can be improved while cost reduced undoubtedly.2. A pattern format is designed independently, which contains more exhaustive control information than the mainstream data formats to improve the sewing performance by shortening the preprocessing delay.3. The specific-function middleware for electro-pattern sewing machine is developed, which enriches the embedded software set of seriate intelligent sewing equipment.
