The Research And Implementation Of Embedded Autolevelling Device Control System

With the improve of spinning technology of our country, the quality of textile attracts peoples' attention day by day. However, autolevelling device works normally or not is closely related to the quality of textile. A control system with great performance and stability is the key and guarantee of autolevelling device working normally. Therefore this article put forward the research and implementation of embedded autolevelling device control system, which is for the purpose of designing a control system that can monitor and control autolevelling device to control autolevelling device efficiently and stably.The system adopts embedded technology, based on high-performance, industrial-grade ARM microprocessor——S3C2410X, uses embedded Linux as OS, use SPI interface to Read/Write I/O Port and control autolevelling device. Control system also connects touch screen. It can conveniently realize the monitor of autolevelling device through the friendly HMI.This article firstly narrates the background and meaning of the research, analyzes the present research status of the similar products in the domestic and foreign. Then it introduces the hardware structure of embedded autolevelling device control system, transplantation technology of embedded OS,selection of embedded GUI and establishing of development platform. After that the article realizes the R/W function of the control system's I/O port, introduces the autolevelling device that the article refers to, and analyzes the control principle and control strategy of autolevelling device. At last the article realizes the control to the autolevelling device and designs embedded HMI.Embedded autolevelling device control system which this article studies and designs conforms to autolevelling device control system automatic and informationalized request. The article has completed SPI interface driver and control program. It has established the solid foundation for finally thrusting this system to the market and widespread application.
