The Research And Development Of Embedded Control Platform Based On Linux

HMI is a typical embedded system with highly autonomous functions.It lies between the field intelligent nodes and the master nodes of the control system;it is the bridge of information interchange.In this paper,HMI in wind power plant is taken as the research object.It is realized by the co-design method with ARM as the hardware platform and the embedded Linux operating system as the software platform,using H9200 and Qt to construct the HMI.The thesis works over system architecture,technology,costing,resource spending and transplant of many kinds of UGI(User Graphic interface).Using cross-complying method to realize the installation,coding,download,debugging Qt on both Linux host computer and ARM,and then summarize a suit of reasonable ways of developing steps.At last,the production is a condensed efficient HMI which also have a touch screen.It has characteristics of transplantable,easy operating and expandable.
